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 cellular networks and more particularly to a method and system for location based call routing in the cellular networks.
BACKGROUND OF THE INVENTION
[0002] A cellular network or mobile network is a telecommunications network where the link is wireless and the network is distributed over land areas called cells, each served by at least one fixed-location transceiver. These base stations provide the cell with the network coverage which can be used for transmission of voice, data, and other types of content.
[0003] When joined together, these cells provide radio coverage over a wide geographic area. This enables numerous portable transceivers (e.g., mobile phones, tablets and laptops equipped with mobile broadband modems, pagers, etc.) to communicate with each other and with fixed transceivers and telephones anywhere in the network, via base stations.
[0004] A cell site, cell phone tower, or cellular base station is a cellular-enabled mobile device site where antennas and electronic communications equipment are placed (typically on a radio mast, tower, or other raised structure) to create a cell, or adjacent cells, in a cellular network. The structure typically supports antenna and one or more sets of transmitter/receivers , digital signal processors, control electronics, a GPS receiver for timing, primary and backup electrical power sources, and sheltering.
[0005] The cellular network has a network of handheld mobile phones (cell phones) in which each phone communicates with the telephone network through a local antenna at a cellular base station (cell site). The coverage area in which service is provided is divided into a mosaic of small geographical areas called "cells", each served by a separate low power multichannel transceiver and antenna at a base station. The cellular devices such as the cell phones within a cell communicate with the system through that cell's antenna.
[0006] When a mobile user moves from one cell to another, their phone is automatically "handed off" to the new cell's antenna, and assigned a new set of frequencies, and subsequently communicates with this antenna. This background handoff process is imperceptible to the user and can occur in the middle of a phone call without any service interruption. Each cell phone has an automated full duplex digital transceiver and communicates with the cell antenna over two digital radio channels in the UHF or microwave band, one for each direction of the bidirectional conversation, plus a control channel which handles registering the phone with the network, dialling, and the handoff process.
[0007] A cellular network mobile phone system gets its name from dividing the service area into many small cells. Typically, a cell tower is located at the edge of one or more cells and covers multiple cells using directional antennas. A common geometry is to locate the cell site at the intersection of three adjacent cells, with three antennas at 120° angles each covering one cell. In another example, the cell tower may be covering and serving eight cells, i.e., eight geographically divided regions.
[0008] With the increasing penetration of cell phone usage, the use of location base services is also increasing. Due to use of higher frequency range, the range of a particular eNodeB/gNodeB has reduced and hence the total number of eNodeB/gNodeB has increased significantly. As a result, it becomes difficult and cumbersome to manage routing data for individual cell. Besides, with the increasing number of service numbers, cells and the, there is undesirable latency and delay in serving such requests as the database to be searched is huge and keeps on increasing as new cell or service numbers are added to the network on an ongoing basis.
[0009] Further, maintenance of such a huge database with ever increasing service request numbers or cell is also cumbersome and prone to errors and bugs.
[00010] There is a need for a system and method to manage such huge database of cellular service number and reduce latency and delay in serving such requests from the cellular devices.

The system 108 is adapted to be embedded within the remote 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 remote server 104, without deviating from the scope of the present disclosure.
[00040] Operational and construction features of the system 108 will be explained in detail with respect to the following figures.
[00041] Referring to FIG. 2, FIG. 2 illustrates a block diagram of the system 108 for location based call routing in the cellular network 106, according to one or more embodiments of the present invention. As per the illustrated embodiment, the system 108 includes one or more processors 202, a memory 204, and an input/output interface unit 206. 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. As per the illustrated embodiment, the system 108 includes one processor 202. 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.
[00042] The memory 204 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 or share data packets over a network service. 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. In an embodiment, the input/output (I/O) interface unit 206 includes a variety of interfaces, for example, interfaces for data input and output devices, referred to as Input/Output (I/O) devices, storage devices, and the like. The I/O interface unit 206 facilitates communication of the system 108. In one embodiment, the I/O interface unit 206 provides a communication pathway for one or more components of the system 108.
[00043] Further, the processor 202, in an embodiment, may be implemented as a combination of hardware and programming (for example, programmable instructions) to implement one or more functionalities of the processor 202. In the examples described herein, such combinations of hardware and programming may be implemented in several different ways. For example, the programming for the processor 202 may be processor-executable instructions stored on a non-transitory machine-readable storage medium and the hardware for processor 202 may comprise a processing resource (for example, one or more processors), to execute such instructions. In the present examples, the memory 204 may store instructions that, when executed by the processing resource, implement the processor 202. In such examples, the system 108 may comprise the memory 204 storing the instructions and the processing resource to execute the instructions, or the memory 204 may be separate but accessible to the system 108 and the processing resource. In other examples, the processor 202 may be implemented by electronic circuitry.
[00044] In order for the system 108 to manage the call routing request, the processor 202 includes a retrieving module 208, a group generation module 210, a mapping module 212 and a routing module 214 communicably coupled to each other.
[00045] The retrieving module 208 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 cellular network 106. Accordingly, the retrieving module 208 is configured to identify each of the at least first UE 102a, the second UE 102b, and the third UE 102c served by at least each of the first base station 110a, the second base station 110b, and the third base station 110c and retrieve a Base Station Identifier (BSID) based on a cell identifier (cell ID) of each of the plurality of identified cells. The Base Station Identifier (BSID) is a unique identifier assigned to a wireless base station or a cell tower that is used to identify and differentiate between the each of the first base station 110a, the second base station 110b, and the third base station 110c in the cellular network 106. In one embodiment, the cell ID refers to the unique identifier assigned to a specific cell in the plurality of identified cells within the cellular network 106.
[00046] As per above embodiment, each of the first base station 110a, the second base station 110b, and the third base station 110c is responsible for providing wireless communication coverage to a specific geographical area known as the plurality of cells. Each cell in the plurality of cells is typically served by each of the first base station 110a, the second base station 110b, and the third base station 110c, and the BSID is used to uniquely identify each of the first base station 110a, the second base station 110b, and the third base station 110c within the cellular network 106. The BSID enables the each of the at least first UE 102a, the second UE 102b, and the third UE 102c to connect and communicate with the appropriate base station 110 as they move throughout the coverage area.
[00047] The BSIDs are used to identify individual base stations, optimize network performance, and enable location based services. The specific format and function of the BSID may vary depending on a wireless communication protocol used in the cellular network. For example, In GSM networks, the BSID is known as the Cell Identity (CID) and is a 16-bit number that is unique within the Location Area Code (LAC). In Universal Mobile Telecommunications System (UMTS) networks, the BSID is known as the NodeB Identity (NID) and is a 28-bit number that is unique within the Radio Network Controller (RNC). In Long term-evolution (LTE) networks, the BSID is known as the Physical Cell Identity (PCI) and is a 16-bit number that is unique within the cell. The BSID is stored in the UE’s memory (as shown in FIG. 3). When each of the at least first UE 102a, the second UE 102b, and the third UE 102c first connects to the cellular network 106, the BSID is used to identify and connect to the each of the first base station 110a, the second base station 110b, and the third base station 110c.
[00048] Further, the base station ID based on the cell ID of each of the plurality of identified cells are stored in the database 216, thereby reducing number of entries at the database 216 pertaining to the plurality of cells served by the at least one base station 110 by a factor.
[00049] The group generation module 210 of processor 202 is communicably connected to the retrieving module 208. The group generation module 210 retrieves the base station ID of each of the at least first UE 102a, the second UE 102b, and the third UE 102c from the retrieving module 208. In an embodiment, the group generation module 208 is configured to perform grouping of each of the first, the second, the third UE (102a, 102b, 102c) logically based upon location of at least first UE 102a, the second UE 102b, and the third UE 102c. More specifically, the group generation module 210 is configured to generate a first group including the plurality of cells based on at least the geographical area. In an embodiment, the plurality of cells includes cell1 referred to a group of at least first UE 102a, the second UE 102b, and the third UE 102c based upon a first geographical area, similarly, cell2 is referred to group of at least first UE 102a, the second UE 102b, and the third UE 102c based on a second geographical area and so on. The group generation module 208 is configured to generate a second group by assigning at least one logical ID to the first group. The configuration and location of least first UE 102a, the second UE 102b, and the third UE 102c depends upon the existing status of the infrastructure of the service provider/operator. In one embodiment, the grouping of plurality of cells and routing are customizable depending upon the requirement of the network operators. The requirement of the network operators is based on at least one of, but not limited to, cell grouping and clustering, dynamic routing policies, Quality of Service (QoS) routing, service differentiation, and policy-based routing.
[00050] The mapping module 112 of the processor 202 is communicably connected to the group generation module 210. The mapping module 212 collects the first group and the second group from the group generation module 210. Further, the mapping module 212 is configured to map a particular service number to the second group. The second group includes at least one logical ID assigned to the first group. The particular service number refers to a special calling number such as “139”, “191”, “1047” used for accessing specific services or functionalities. The particular service numbers are typically assigned by the network operators and are often associated with particular services such as, but not limited to, customer support, directory assistance, emergency services, or value-added services like weather updates, and news alerts.
[00051] The routing module 214 of the processor 202 is communicably connected to the mapping module 212. The routing module 214 collects the mapped service number to the second group from the mapping module 212. Further, the routing module 214 is configured to define a routing path based on the mapped service number to the second group and route a received call related to the service number to a destination via one of the routing paths and current geographical location of least first UE 102a, the second UE 102b, and the third UE 102c based on the mapped service number to the second group.
[00052] Referring to FIG. 3, FIG. 3 describes a system 108 for managing the location based call routing in the cellular network 106. It is to be noted that the embodiment with respect to FIG. 3 will be explained with respect to the first UE 102a and the system 108 for the purpose of description and illustration and should nowhere be construed as limited to the scope of the present disclosure.

The first UE 102a includes one or more primary processors 305 coupled with a memory 310 storing instructions which are executed by the one or more primary processors 305. Execution of the stored instructions by the one or more primary processors 305 enables the first UE 102a to transmit a service request from the at least first UE 102a, the second UE 102b, and the third UE 102c.
[00053] The each of at least first UE 102a, the second UE 102b, and the third UE 102c may comprise a memory such as a volatile memory (e.g., RAM), a non-volatile memory (e.g., disk memory, FLASH memory, EPROMs, etc.), an unalterable memory, and/or other types of memory. In one implementation, the memory might be configured or designed to store data. The data may pertain to attributes and access rights specifically defined for at least first UE 102a, the second UE 102b, and the third UE 102c. The each of at least first UE 102a, the second UE 102b, and the third UE 102c may be accessed by the user, to initiate call request to the base station 110. The each of at least first UE 102a, the second UE 102b, and the third UE 102c may be configured to connect with at least each of the first base station 110a, the second base station 110b, and the third base station 110c through the cellular network 106.
[00054] As mentioned earlier in FIG. 2, the processor 202 of the system 108 includes the retrieving module 208, the group generation module 210, the mapping module 212 and the routing module 214 communicably coupled to each other. The retrieving module 208 is configured to identify a plurality of cells served by at least one base station 110 and to retrieve the base station ID from the Base Station Identifier (BSID) based on the cell ID of each of the plurality of identified cells. Further, the grouping generation module 210 generates a first group including the plurality of cells based on a geographical area and a second group by assigning at least one logical ID to the first group. The mapping module 212 maps a particular service number to the second group. The routing module 214 defines a routing path based on the mapped service number to the second group and route, a received call related to the service number to a destination via one of, the routing path and current geographical location of the each of at least first UE 102a, the second UE 102b, and the third UE 102c based on the mapped service number to the second group. Further, the processor 202 of the system 108 is coupled with the primary processor 305 of the first UE 102a.
[00055] For the sake of brevity, it is to be noted that similar description related to the working and operation of the system 108 as illustrated in FIG. 2 has been omitted to avoid repetition. The limited description provided for the system 108 in FIG. 3, should be read with the description as provided for the system 108 in the FIG. 2 above, and should not be construed as limiting the scope of the present disclosure.
[00056] Referring to FIG. 4, FIG. 4 is an exemplary embodiment of a routing module of the system 108 of FIG. 2, according to various embodiments of the present invention.
[00057] As mentioned earlier in FIG. 2, the processor 202 of the system 108 includes the retrieving module 208, the group generation module 210, the mapping module 212 and the routing module 214 communicably coupled to each other. The group generation module 210 includes grouping and mapping of the plurality of cells (cell1 401, cell2 402, cell3 403) to a predetermined Logical Id (L-ID1, L-ID2, L-ID3, etc.). In an embodiment, the grouping is fixed and is not changed in real time, irrespective of the change or addition of new service number. Once the plurality of cells is grouped with the logical ID (L-ID1), the association of the plurality of cells and the associated logical ID (L-ID1) will be maintained in the database 216, irrespective of whether the service number is added, removed or modified.
[00058] For example, Table 1 is shown below illustrating the grouping of the plurality of cells such as cell1 401, cell2 402 and cell3 403, which may be grouped into a single group and assigned to the single logical ID L-ID1 which in turn may be associated with the special calling number such as “139”, “191”, “1047” and the like., the special calling numbers are dedicated calling numbers which are frequently used by the each of at least first UE 102a, the second UE 102b, and the third UE 102c for general or dedicated to specific services as per the operator, service provider of regulatory authorities. The L-ID1 may be associated with “139”, the L-ID2 may be associated with “139”, and the L-ID3 may be associated with “1047.”
[00059] Table 1:
Cell Logical Id Assigned special calling number
Cell1 L-Id1
139
Cell2
Cell3 up to cell8
Cell9 L-Id2
191

Cell10
Cell11 up to cell 16

[00060] The special calling numbers such as “139”, “191”, “1047” may be referred to as level one service numbers and may vary with the service provider and operator.
[00061] Further, when at least cell1 401 makes a call from geographical area one (Area 1) to the special calling number “139”, the call is routed via a single route R1 associated with L-Id1(shown below Table 2). This increases the process efficiency and reduces the latency in servicing the requests.
[00062] Table 2 illustrates the mapping of various logical IDs (L-ID1, L-ID2, L-ID3, etc.) to specific associated routes (R1, R2, R3, etc.) and corresponding special calling numbers.
[00063] Table 2:
Special calling no. Logical Id Route Geographical Location
139 L-Id1 R1 Area1
191 L-Id2 R2 Area2
1047 L-Id3 R3 Area3

[00064] Further, grouping together of the plurality of cells for servicing the requests reduces the effort required in maintaining the database 216 and improves in the servicing of the request faster, efficient and reduces the latency.
[00065] In an embodiment, the method and system of the invention can be configured to map a particular cellular network 106 area to a specific logical Id as per the requirement of the user or operator. The routing call service is effectively based upon the location of the plurality of cells and the special calling number being called by the at least one UE 102 is at least one of a first UE 102a, a second UE 102b, and a third UE 102c.
[00066] Referring to FIG. 5, FIG.5 shows a flow diagram of a method 500 for location based call routing in the cellular network 106, according to various embodiments of the present invention. For the purpose of description, the method 500 is described with the embodiments as illustrated in FIG. 2 and should nowhere be construed as limiting the scope of the present disclosure.
[00067] At step 502, the method 500 includes the step of identifying of cells by each of the first base station 110a, the second base station 110b, and the third base station 110c and retrieving the base station ID based on the cell ID by the one or more processors 202. The retrieving module 208 is configured to identify plurality of cells and retrieve the cell ID of each identified cells. Further, the base station ID based on the cell ID of each of the plurality of identified cells are stored in the database 216, thereby reducing number of entries at the database 216 pertaining to the plurality of cells served by at least each of the first base station 110a, the second base station 110b, and the third base station 110c by a factor. At step 504, the method 500 includes the step of generating first group of the plurality of the cells based on a geographical area and generating a second group by assigning at least one logical ID to the first group.
[00068] At step 506, the method 500 includes the step of mapping a particular service number to the second group. The second group includes at least one logical ID to the first group. For example, the grouping of plurality of the cells such as cell1 401, cell2 402 and cell3 403, which may be grouped into a single group and assigned to a single logical ID L-ID1 which in turn may be associated with a special calling number such as “139”, “191”, “1047” and the like. The special calling numbers such as “139”, “191”, “1047” may be referred to as level one service numbers and may vary with the service provider and the operator.
[00069] At step 508, the method 500 includes the steps of defining of final routing path based on the mapped service number to the second group.
[00070] At step 510, the method 500 includes the step of routing the received call related to the service number to a destination via one of, the routing path and current geographical location of each of the at least first UE 102a, the second UE 102b, and the third UE 102c user based on the mapped service number to the second group. For example, a group of the plurality of cells (for example, CD1) cell1 401, cell2 402, or cell3 403, is mapped to L-ID1, which in turn is associated with special calling number “139”. When at least the cell (cell1 401) in a group of the plurality of cells (for example, CD1) makes a call to the special calling number “139”, the call is routed via a single route R1 associated with L-ID1. The grouping of plurality of cells and routing are customizable depending upon requirement of network services and network operators.
[00071] 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 identify a plurality of cells served by at least one base station. The processor 202 is further configured to retrieve, the base station ID based on the cell ID of each of the plurality of identified cells. The processor 202 is further configured to generate the first group including the plurality of cells based on a geographical area and a second group by assigning at least one logical ID to the first group. The processor 202 is further configured to map, a particular service number to the second group. The processor 202 further defines, a routing path based on the mapped service number to the second group; and route, a received call related to the service number to a destination via one of, the routing path and current geographical location of a User Equipment (UE) 102 user based on the mapped service number to the second group.
