THE FOLLOWING SPECIFICATION PARTICULARLY DESCRIBES THE NATURE OF THIS INVENTION AND THE MANNER IN WHICH IT IS TO BE PERFORMED.

FIELD OF THE INVENTION
[0001] The present invention relates to the field of wireless communication system, and more particularly relates to a method and a system for message manipulation in a communication network.
BACKGROUND OF THE INVENTION
[0002] In a communication network, back-to-back releases are needed for adding or removing something from a message, which is received from a user equipment (UE) or from a previous IP Messaging Service (IMS) node. For example, in a scenario when a new device enters the communication network (system), the new device or previous IMS node may send some malfunctioning header or header with value which is not supported in network or header without exact value which is required to provide required service by network, to a System Information Block (SIB) which is not handled by the communication network. Such malfunctioning header or header with inappropriate value may not be compatible with the IMS nodes present in the communication network. As a result, this can lead to breakdown in the entire communication network, thereby causing downtime for applying new releases to handle such messages. Call failures may also increase due to such behavior of such device or node.
[0003] In the above scenarios, it is therefore required to provide a patch so that a call through the new device is successfully delivered. However, this makes the entire process complicated and introduces downtime.
[0004] Therefore, there is a need for solutions for configuring the headers of the new devices in the network in real-time in an effective and simple manner.

The system 108 is adapted to be embedded within the server 104 or is embedded as the individual entity. However, for the purpose of description, the system 108 is described as an integral part of the server 104, without deviating from the scope of the present disclosure. The system 108 is configured to manipulate message in the communication network 106.
[0036] Operational and constructional features of the system 108 will be explained in detail with respect to the following figures.
[0037] Referring to FIG. 2a, FIG. 2a illustrates an exemplary block diagram of the system 108 according to one or more embodiments of the present invention. In this regard, the system 108 includes one or more processors 202, a memory 204, a transceiver 206, a determination unit 210, a selection unit 212, a manipulation unit 214. The one or more processors 202, hereinafter referred to as the processor 202, may be implemented as one or more microprocessors, microcomputers, microcontrollers, digital signal processors, central processing units, state machines, logic circuitries, single board computers, and/or any devices that manipulate signals based on operational instructions. However, it is to be noted that the system 108 may include multiple processors as per the requirement and without deviating from the scope of the present disclosure. Among other capabilities, the processor 202 is configured to fetch and execute computer-readable instructions stored in the memory 204.
[0038] The memory 204 is communicably connected to the processor 202 which is configured to store one or more computer-readable instructions or routines in a non-transitory computer-readable storage medium, which may be fetched and executed to create or share data packets over the communication network 106. The memory 204 may include any non-transitory storage device including, for example, volatile memory such as RAM, or non-volatile memory such as EPROM, flash memory, and the like.
[0039] The transceiver 206 of the processor 202 is communicably connected to each of the at least first UE 102a, the second UE 102b, and the third UE 102c via the communication network 106. Accordingly, the transceiver 206 is configured to receive a message request from the UE 102. In one embodiment, the received message includes plurality of headers. In another embodiment, the transceiver 206 is configured to receive a message request from any Internet Protocol Multimedia Subsystem (IMS) node.
[0040] The determination unit 210 of the processor 202 is configured to determine at least one header among the plurality of headers that requires manipulation. In other words, the determination unit 210 determines a corrupted header or an inappropriate header among the plurality of headers in the message that is received at the transceiver 206. The determination unit 210 checks the plurality of headers to detect that at least one header of the message is malfunctioning. For example, the UE 102 transmits message which includes the plurality of headers. The determination unit 210 checks each of the plurality of headers and determines whether each of the plurality of headers are compatible with a communication device 314 (as shown in FIG. 3). Hereinafter, for the purpose of description, the communication device 314 is referred to as the called device 314, without deviating from the scope of the present disclosure. When at least one header among the plurality of headers is not compatible with the called device 314, the determination device 210 identifies malfunctioning of that one header among the plurality of headers which is not compatible with the called device 314.
[0041] The selection unit 212 of the processor 202 is configured to select at least one of a plurality of manipulation techniques. These plurality of manipulation techniques, for example, can be implemented as logics which can be applied to the at least one header. The selection unit 212 selects the at least one of the plurality of manipulation techniques based on one or more pre-defined parameters including at least one of, priority, trigger point and action and a combination thereof.
[0042] In one embodiment, the plurality of manipulation techniques include removing, modifying or updating a header with predefined values. In another embodiment, the plurality of manipulation techniques of the header involves forcefully removing, adding, appending, replacing or modifying domain parameters in a Session Description Protocol (SDP) header as well as body and adding media attributes to media streams to improve efficiency.
[0043] The manipulation unit 214 of the processor 202 is configured to manipulate in run time, the at least one header that requires manipulation by applying the at least one selected manipulation technique to the at least one header.
[0044] Referring to FIG. 2b, FIG. 2b illustrates an exemplary block diagram of an architecture for the system 102 associated with a System Information Block (SIB) for message manipulation in a communication network 106, according to one or more embodiments of the present invention.
[0045] In accordance with some embodiments as shown in FIG. 2b, SIB is a product comprising the functionalities of three Internet Protocol (IP) Multimedia Subsystem (IMS) core network nodes namely Serving Call Session Control Function (S-CSCF), Interrogating Call Session Control Function (I-CSCF) and Breakout Gateway Control Function (BGCF). SIB provides stack-less Session Initiation Protocol (SIP) communication among I-CSCF, S-CSCF and BGCF on a same Instance of SIB. SIB also serves all the standard functionalities of the nodes (I-CSCF, S-CSCF and BGCF) in the communication network 106.
[0046] In one embodiment, I-CSCF is responsible for onward routing of SIP messages to an appropriate S-CSCF for a given subscriber. This routing capability is utilized in specific scenarios only, such as during registration in order to assign or ascertain the S-CSCF which should be used. Routing SIP message arriving from another SIP network is also a responsibility of the I-CSCF. The I-CSCF queries a Home Subscriber Server (HSS) in order to obtain the address of the relevant S-CSCF for a particular subscriber or user to process SIP message requests. Mw interfaces between the I-CSCF and the S-CSCF within the same network are considered to be internal IMS interfaces.
[0047] In one embodiment, S-CSCF is a primary node in the IMS responsible for session control. Subscribers will be allocated a S-CSCF for the duration of their IMS registration in order to facilitate routing of SIP message as part of service establishment procedures. The S-CSCF functions as a registrar and enables the network location information of the UE 102 to be available at the HSS. The S-CSCF provides determination to allow or deny services for the UE 102.
[0048] In one embodiment, BGCF is an IMS element that chooses the network where a Public Switched Telephone Network (PSTN) breakout happens. If the breakout occurs in the same communication network as the BGCF, then the BGCF selects a Media Gateway Control Function (MGCF) which will be responsible for the interworking with the PSTN. The MGCF facilitates call control, routing, and interfacing Packet Switch (PS) domain to Circuit Switch (CS) domain when interworking between the IMS and PSTN is required. A Mj interface is SIP based interface between the BGCF and the MGCF. The Mj interface is used to convey SIP messages between the BGCF and the MGCF for interworking with PSTN or circuit switched networks. The Mj interface carries exchange of sessions with the MGCF that the BGCF has selected to provide session breakout to the PSTN or Circuit Switched Networks. A Mi interface is the SIP based interface and used to exchange messages between the S-CSCF and the BGCF for inter-working with the PSTN. The Mi interface allows the S-CSCF to forward the SIP messages to the BGCF for the purpose of MGCF selection.
[0049] In one embodiment, a Proxy Call Session Control Function (P-CSCF) is an edge access function which is the entry point for a UE 102 to request services from the communication network 106 such as an Internet protocol (IP) Messaging Service (IMS) network. The role of this P-CSCF is to function as a proxy by accepting incoming requests and forwarding incoming requests to the at least one of, I-CSCF, S-CSCF and BGCF of the SIB. The Mw interface is used for communication between the P-CSCF, the CSCF and the S-CSCF. The Gm Interface is key to all user based communication . The Gm Interface is used between the UE 102 and the P-CSCF for multiple purposes such as registration, de-registration, incoming calls, outgoing calls, SIP signaling and any type of communication between UE 102 and IMS network.
[0050] In one embodiment, a Telephony Application Server (TAS) contains a logic that facilitates services related to call such as digit analysis, routing, call setup, call waiting, call forwarding, conferencing. In another embodiment, TAS is used within the IMS network in order to facilitate establishment procedures related to a call, as well as supporting services such as Calling Party ID, Call Transfer and Call Barring. An IMS Service Control (ISC) interface is another SIP based connectivity which enables connectivity between the S-CSCF and the TAS. This ISC interface interacts with the MMTel supplementary services implemented on the TAS where the ISC interface is used for requesting services from the TAS. The ISC interface also supports TAS initiated requests to the IMS.
[0051] In one embodiment, a Diameter Routing Agent (DRA) provides a routing capability in real time which ensures that the messages are routed to an appropriate destination. The DRA acts as a mediator between the S-CSCF, I-CSCF and the HSS. The HSS is the main subscriber database used within the IMS which provides details of the subscribers to other entities within the network. A Cx interface is used between the S-CSCF, the I-CSCF and the HSS for downloading subscriber data to the S-CSCF from the HSS. The Cx interface uses a diameter protocol and enable IMS registration and passing of subscriber data to the S-CSCF. The diameter protocol provides Authentication, Authorization, and Accounting (AAA) messaging services for network access and data mobility applications in 3G, IP Multimedia Systems (IMS), and LTE/4G networks.
[0052] In one embodiment, a Multimedia Resource Function (MRF) supports multimedia services and is responsible for carrying out a variety of processing tasks on media streams associated with the multimedia services. The MRF is communicably connected to the S-CSCF. A Mr interface between the MRF and the S-CSCF provides MRF connectivity to the SCSCF. The Mr interface allows interaction with the media resource for specific supplementary services (e.g. conference call) on Control Plane (CP).
[0053] In one embodiment, a Lawful Interception Management System (LIMS) is a proven solution for network operators and service providers to automate the administrative and operative tasks related to lawful interception. A X1/X2 is an interface between the LIMS and the S-CSCF. The X1 is the interface that allows the LIMS to provision tasks on a Network Function (NF). A task represents an intercept on a target. As long as the task is provisioned, the NF is instructed to intercept communication. The intercepted communication is delivered using the X2 interface.
[0054] In one embodiment, the three functional nodes (S-CSCF, I-CSCF, BGCF) are merged in order to create a SIB, that facilitates in achieving better network utilization and a capacity improvement is achieved by stack-less communication.
[0055] The SIB, performs a message manipulation at runtime. One of the key advantages of the techniques of the present disclosure is the Session Description Protocol (SDP) part. The SDP part is basically the body of the SIB message. Usually, SIB message header can be manipulated. Further, the present techniques provide for a flexibility of manipulating the SDP body as well, which is for the media or the media component, so, that also can be validated.
[0056] FIG. 3 illustrates an exemplary block diagram of an architecture for the system 108 of FIG. 2, according to one or more embodiments of the present invention. More specifically, FIG. 3 illustrates the system 108 configured for message manipulation in a communication network. It is to be noted that the embodiment with respect to FIG. 3 will be explained with respect to the UE 102 for the purpose of description and illustration and should nowhere be construed as limited to the scope of the present disclosure. The FIG. 3 includes a UE 102 (also referred to as calling device), a plurality of nodes for example a first node 310, a second node 312, and a called device 314. The UE 102, the first node 310, the second node 108 and the called device 314 are communicably connected with the system 108 which is SIB.
[0057] For the purpose of description of the exemplary embodiment as illustrated in FIG. 3, the User Equipment (UE) 102 uses network protocol connection to communicate with the system 108. Accordingly, the UE 102 is configured to transmit a message to the system 108 including plurality of headers.
[0058] In an embodiment, the network protocol connection is the establishment and management of communication between the UE 102 and the system 108 over the communication network 106 using a specific protocol or set of protocols. The network protocol connection includes, but not limited to, SIB protocol, Session Description Protocol (SDP), Transmission Control Protocol (TCP), User Datagram Protocol (UDP), File Transfer Protocol (FTP), Hypertext Transfer Protocol (HTTP), Simple Network Management Protocol (SNMP), Internet Control Message Protocol (ICMP), Hypertext Transfer Protocol Secure (HTTPS) and Terminal Network (TELNET).
[0059] In an embodiment, UE 102 includes a primary processor 302, and a memory 304. In alternate embodiments, the UE 102 may include more than one primary processors 302 as per the requirement of the communication network 106. The primary processors 302, may be implemented as one or more microprocessors, microcomputers, microcontrollers, digital signal processors, central processing units, state machines, logic circuitries, single board computers, and/or any devices that manipulate signals based on operational instructions.
[0060] In an embodiment, the primary processor 302 is configured to fetch and execute computer-readable instructions stored in the memory 304. The memory 304 may be configured to store one or more computer-readable instructions or routines in a non-transitory computer-readable storage medium, which may be fetched and executed to create and transmit a message to the system 108. The memory 304 may include any non-transitory storage device including, for example, volatile memory such as RAM, or non-volatile memory such as disk memory, EPROMs, FLASH memory, unalterable memory, and the like.
[0061] For example, when a new device such as the UE 102 is introduced in the communication network 106, the UE 102 transmits a message to the system 108 in order for establishing a call from the UE 102 to the called device 314. The message transmitted to the system 108 includes plurality of headers. As will be understood by those skilled in the art, the header refers to supplemental data placed at the beginning of a block of data being stored or transmitted. In data transmission, the data following the header is sometimes called the payload or body. The transceiver 206 receives the message transmitted from the UE 102 which includes the plurality of headers. These plurality of headers includes at least one malfunctioning header determined by the determination unit 210 which is non-compatible with the at least one of a first node 310, a second node 312 and the called device 314, this non-compatibility of the header is due to the header being corrupted or includes inappropriate values. The malfunctioning header is not handled by the nodes i.e. the first node 310, the second node 312 and the called device 314, thereby leading to the problems including breakdown of the entire communication network 106. Further, a call from the UE 102 will not get matured in the communication network 106, and hence the UE 102 will not be able to make any calls to the called device 314. In another example, another problem includes, if the UE’s 102 name has a specific naming format of 20 digits or 50 characters, the UE 102 transmits a 1000 characters long name. So, if this message reaches a called device 314, the called device 314 suffers. The called device 314 is not able to handle these many characters. As a result network services will be seriously impacted.
[0062] In order to solve the problems, some manipulation techniques are required to be implemented with respect to the malfunctioning or corrupted headers. The determination unit 210 determines the at least one header that requires manipulation based on the non-compatibility with the at least one of a first node 310, a second node 312 and the called device 314. For example, when the UE 102 transmits the message to the processors 202 including the plurality of headers, the determination unit 210 of the processors 202 checks whether the plurality of headers are compatible with the at least one of the first node 310, the second node 312 and the called device 314. In response to checking the plurality of headers, the determination unit 210 identifies that at least one header is malfunctioning when the at least one header is not compatible with the at least one of the first node 310, the second node 312 and the called device 314. Further, the determination unit 210 infers that the malfunctioned header requires manipulation. The selection unit 212 selects at least one of the plurality of manipulation techniques based on one or more pre-defined parameters.
[0063] In one or more embodiments, the plurality of manipulation techniques are based on one or more predefined parameters with respect to the malfunctioning headers. The manipulation techniques include at least one of removing a malfunctioning header, modifying a malfunctioning header, or updating a malfunctioning header with different header values. The one or more predefined parameters include (a) priority, (b) trigger points, and (c) action implemented based on the different header values. Various combinations of these one or more predefined parameters are implemented based on the different header values of the malfunctioning headers. When there are plurality of headers causing a problem, certain malfunctioning headers are prioritized over other malfunctioning headers, from which the problems are required to be solved. In other words, firstly, the malfunctioning headers and the level of the problem associated with the malfunctioning headers are identified and these malfunctioning headers are arranged in a hierarchy based on the levels of the problems to be resolved with respect to the UE 102 and the called device 314.
[0064] For example, the priorities are given only when there are plurality of headers present or multiple manipulations are required. As such, which manipulation is to be given a higher priority is decided by the one or more predefined parameters such as priority. In other words, if there are 10 types of manipulations that are required for a device such as UE 102, first these manipulations are checked, to determine which manipulations should be taken up on priority. For example, the plurality of headers are associated with (i) ‘bandwidth issue’, or (ii) ‘device not registered’. As such, the ‘device not registered’ is given a first priority or higher priority. Therefore, the problem associated with the ‘device not registered’ is solved first. Once this problem (i.e., ‘device not registered’) is resolved, the next priority of ‘bandwidth issue’ is considered and resolved.
[0065] The one or more predefined parameters further includes a trigger point, let's consider a user header with a device name X, and let us consider that the issue is with respect to particular version of the device X. So, this version is implemented as a trigger point, such that the only invite originating from the device X with that particular version will get triggered for the manipulation. There can be multiple trigger points, for example, with respect to a caller party etc. Accordingly, there can be multiple combinations. These combinations can be defined dynamically in real time.
[0066] The one or more predefined parameters further include actions to manipulate headers included in the message. These actions include removing, modifying, or updating the values of the malfunctioning or corrupted headers.
[0067] Subsequent to selecting at least one of the plurality of manipulation techniques based on one or more pre-defined parameters, the manipulation unit 214 manipulates the at least one malfunctioned header that requires manipulation in run time by applying the at least one selected manipulation technique to the at least one malfunctioned header. The manipulation unit 214 also manipulates a body of the message by one of, removing, adding, appending, replacing and modifying domain parameters of the body and adding media attributes to media streams of the body. Thereby the problems caused by the malfunctioning headers are resolved by the system 108 which leads to the successful establishment of a call between the UE 102 and the called device 314.
[0068] Referring to FIG. 4, FIG. 4 is a flow chart illustrating a method 400 of message manipulation in a communication network. For the purpose of description, the method 400 is described with the embodiments as illustrated in FIG. 2 and should nowhere be construed as limiting the scope of the present disclosure.
[0069] At step 402, the method 400 includes the step of receiving, a message from a User Equipment (UE) 102 via a transceiver 206. In one embodiment, the message received by the transceiver 206 includes a plurality of headers and the plurality of headers consists of multiple values. In one embodiment, the message pertains to the UE 102 establishing a call with a communication device such as a called device 314.
[0070] At step 404, the method 400 includes the step of determining, at least one of the plurality of headers that requires manipulation. In one embodiment, while transmitting the message from the UE 102 to the system 108, the UE 102 transmits some malfunctioning header or header with inappropriate value to the system 108. The determination unit 210 of the processor 202 determines at least one header among the plurality of headers that requires manipulation by checking the plurality of headers to detect the at least one header of the message is malfunctioning. For example, when a transceiver 206 receives a header from a new UE 102, the called device 314 is not able to handle that header or the header is non compatible with the called device 314. This non-compatibility of the header is due to the header being corrupted.
[0071] At step 406, in order to overcome the above problems, the method 400 includes the step of, selecting at least one of a plurality of manipulation techniques. The selection unit 212 selects at least one of the plurality of manipulation techniques based on one or more pre-defined parameters. The one or more pre-defined parameters with respect to the headers includes, priority, trigger points, and actions. Various combinations of these one or more pre-defined parameters are implemented based on the different header values.
[0072] The priority with respect to the plurality of headers indicates that the certain malfunctioning headers have higher priority as compared to other malfunctioning headers. The priority includes hierarchy of issues to be resolved with respect to the UE and the called device 314. Further, the trigger point associated with the plurality of headers are different. The trigger point includes at least one of, specific version of the UE and the called device 314. Action refers to whether to remove the malfunctioning header, or to update the malfunctioning header, or simply replace the malfunctioning header with another value. In other words, actions relate to adding, removing, or modifying the malfunctioning headers. As such, there can be actions based on the parameters of priority and trigger point.
[0073] At step 408, the method 400 includes the step of, manipulating in run time, the at least one header that requires manipulation by applying the at least one selected manipulation technique to the at least one header. In an embodiment, in order to manipulate the malfunctioned header included in the message, the malfunctioned header is removed, updated or replaced with another value. An example of how the at least one header is manipulated is provided herein. Let us assume there are some predefined requirements in order to successfully establish call from the UE 102 to the called device 314. The predefined requirements pertain to at least one of, but not limited to, a range of pre-defined values included in the plurality of headers which are compatible to establish the call from the UE 102 to the called device 314. Based on the comparison between the value included in at least one of the header with the range of the pre-defined values, the processor 202 identifies that the value included in at least one header is not within the range of pre-defined values. Based on this, the processor 202 identifies the difference between the value included in at least one of the header and the range of the pre-defined values. Thereafter, based on the difference, the processor 202 selects at least one manipulation technique and manipulates the identified value included in the at least one header in run time by changing or updating the identified value as per the range of the pre-defined values. In particular, the processor 202 changes or modifies the identified value such that the manipulated value is within the range of the pre-defined values which are compatible to successfully establish the call from the UE 102 to the called device 314. As such, the proposed techniques require no new development, and the problem is solved during run-time thereby preventing any downtime in the communication network 106. Moreover, there is no need to apply reapply the patch, there is no need to wait for the patch to arrive. Instead, the proposed techniques provide for simply configuring SIP nodes such as I-CSCF, S-CSCF and BGCF so that the value is changed or configured. The value therefore gets modified in the SIP node, and the call with respect to the UE 102 works like a normal call. As such the solution is achieved during runtime, and there is no downtime in the environment 100.
[0074] The present invention further discloses a non-transitory computer-readable medium having stored thereon computer-readable instructions. The computer-readable instructions are executed by a processor 202. The processor 202 is configured to receive a message from a User Equipment (UE), the message including a plurality of headers. The processor 202 is further configured to determine, at least one of the plurality of headers that requires manipulation. In response to determining that the at least one header requires manipulation the processor 202 is further configured to select at least one of a plurality of manipulation techniques. The processor 202 is further configured to manipulate in run time the at least one header that requires manipulation by applying the at least one selected manipulation technique to the at least one header, and thereby manipulating message in a communication network 106.
