DESC:TECHNICAL FIELD
[001] The present disclosure relates wireless communication systems. More particularly, the present invention relates to dual cellular modem with dual sim dual active (DSDA) data connection with Global System for Mobile Communication (GPS) and Zigbee Interfaces.

BACKGROUND
[002] Background description includes information that may be useful in understanding the present invention. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed invention, or that any publication specifically or implicitly referenced is prior art.
[003] Wireless communication has come of ages from telegraphic signals to hand held mobile devices. These systems are rapidly growing in usage. Further, wireless communication technology has evolved from voice - only communications to also include the transmission of data, such as Internet and multimedia content. Mobile internet has grown from its initial phase of 2G (GPRS) to 3G (UMTS) to 4G (LTE) in last 20 years. Evolution visible in communication from Single SIM (subscriber identity module or subscriber identification module) to Dual Sim system in the last decade is as well remarkable. Dual SIM telephones are systems that can hold two SIM cards and provides flexibility in service and other options.
[004] The Korean application KR2008058613A discloses a dual mode terminal. The mobile phone uses the two radio stacks reaching signal processing functions and standby functions. Some dual SIM mobile phones can be active on two networks simultaneously in standby mode. In dedicated mode, the phone is only active on the network on which the call is going on. They are called DSDS i.e. “Dual SIM dual standby”. In DSDS devices with two SIMs, user can set one sim for designated data subscription, where the chosen subscription will serve as the provider of data service to the wireless devices and mobile device will continue to receive voice calls on both the subscription. Additionally, each subscription may be associated with one or more technology types.
[005] Patent US20150023258A1 provide a way of enabling two active Voice communications simultaneously on both SIMs, by using one transmit chain with time sharing and 1 or 2 Receiver chain for communication.
[006] Patent US9794403B2 did enhancement to DDS in earlier approach by providing data transfer on two active Voice communication based on which of them is on standby. But still, only one DDS service with DSDS or DSDA voice communication is available and dual sim with dual active DDS service isn’t available in mobile or wireless devices. Brief Summary of prior work and problem statement is defined in below Table 1.

[007] Conventionally, a dual active device has two transceivers and may support two concurrently active connections when two or more SIMs is installed. The two concurrently active connections may include some combination of circuit-switched (CS) and packet-switched (PS) traffic. If two SIMs are active on traffic calls in a dual-active device, the remaining SIMs generally enters an out-of-service (OOS) state.
[008] Therefore, there exists a need to provide improved and efficient equipment having dual cellular modem with dual sim dual active (DSDA) data connection with Global System for Mobile Communication (GPS) and Zigbee Interfaces.

[0058] In an exemplary embodiment, a special design algorithms are used which control the modem operations. Route management operation was also designed which ensure both SIMs are able to send their data on their respective channels.
[0059] FIG. 4 illustrates an exemplary flowchart of modem management operations, in accordance with an exemplary embodiment of the present disclosure.
[0060] As shown in FIG. 4, in order to provide dual sim dual active data connection on designed integrated card, software does important role of managing and controlling system operation like connection establishment, disconnection detection and redialling, system route management, modem configuration management, GPS location detection, Zigbee interfacing. Designed software is compatible with red hat Linux as it uses some of driver level operations and modem manager services of OS. At present, it has been tested on Enterprise Linux system.
[0061] In an exemplary embodiment, FIG. 4 describes the modem management process which start with Modem Initialization in which running software captures the system level details like type of running OS, its version, number of modems attached to the system, their hardware handle and dmesg logs, modem logical handle in the system etc. Beside this, software also initializes its logging activity, purging property, device Id, software version etc. Now based on first step, next step is to Checking Modem Parameters like which bearer is attached to which modem, their service provider Identifier, registration status of the sim, type of access technology available for the connection, available signal strength at the modem, sim identifier available at the modem, their primary TTY port for communication etc. These parameters help to dial and establish connection at the modem. It is very important to identify the correct operator and then dial correct connection to the respective modem, else modem will freeze by retrying to establish wrong connection. After dialing both connections, system have two active data connection for communication. Internally modem managers uses pppd demon to provide IP address to system by giving additional network interface for each connection. Generally, pppd add interface ppp0 and ppp1 for dual modem. Both interface will get respective IPs which are available in their modems.
[0062] After establishing both connections, continuous monitoring for disconnection is required on periodic basis. As designed system has been tested in a moving vehicle, we have used periodicity of 20 sec to check disconnection. For checking disconnection, we need to check Connection at Interface Level and at Modem Level, as connection was established first at the Modem and then it is then passed to OS in form of network interface by the pppd demon. So monitoring connection at both points are provided. Also during testing of developed system, issue of synchronization of connection at Modem and OS was faced, after which we decided to include monitoring at both points.
[0063] FIG. 5 illustrates an exemplary flowchart of modem reconnection operations, in accordance with an exemplary embodiment of the present disclosure.
[0064] In an exemplary embodiment, a flow chart in FIG. 5 defines reconnection approach in which software after checking disconnections at both modems, redial to reconnect the modem/modems which has/have been disconnected. Our proposed approach has used hardware ‘SoftReset’ pins which the power reboots of the modem in case modem is not able to get connection after many retries or get hanged for specific interval of time. Here we have used 3 minutes ModemResetTimmer where we wait for 3 minutes (or 12 retries) in order to get the connection back. In case modem is not able to provide connection, ‘SoftReset’ pin of the modem is used to reset the modem after which modem goes from initialization phase to connection phases. ‘SoftReset’ has played very important role in bringing back connection in cases like hanging of modem due to frequent disconnection or due to handoff not done properly etc. In case modem connection is successful, ModemResetTimer has been reset to zero and then checking of disconnection at interface and modem level continues as defined in the Flow chart in FIG. 4
[0065] It may be appreciated that in order to provide Dual sim dual active connections, one of main task is to ensure both SIMs are able to send their data on their respective channels and for that it is ensured to maintain proper routes for both data channels. In the present invention, to achieve the above all the routes for each data channels are pre-defined and whenever connection gets activated successfully, their routes are added instantly through parallel threads. The present invention has used Linux system command in order to add routes for each of data connections.
[0066] According to the present invention, a dual active data streams connection on a single machine is provided. This will lead to following usage in future as:
i. As system has 2 parallel data streams, it will provide flexibility to running application to choose their data stream.
ii. It will provide parallel active data connection in the system where frequent disconnection will be available. For example, in running vehicles like Train, buses, cars etc. it will provide redundancy in the system to increase the data availability.
iii. It will also provide way for better utilization and cost optimization of Data stream service in case user has cheaper data connection in any one of available two data stream service.

[0073] Although the dual modem mobile equipment (ME) (100) has been elaborated as above to include all the main modules, it is completely possible that actual implementations may include only a part of the proposed modules or a combination of those or a division of those into sub-modules in various combinations across multiple devices that can be operatively coupled with each other, including in the cloud. Further the modules can be configured in any sequence to achieve objectives elaborated. Also, it can be appreciated that proposed system can be configured in a computing device or across a plurality of computing devices operatively connected with each other, wherein the computing devices can be any of a computer, a laptop, a smartphone, an Internet enabled mobile device and the like. All such modifications and embodiments are completely within the scope of the present disclosure.
[0074] As used herein, and unless the context dictates otherwise, the term “coupled to” is intended to include both direct coupling (in which two elements that are coupled to each other or in contact each other) and indirect coupling (in which at least one additional element is located between the two elements). Therefore, the terms “coupled to” and “coupled with” are used synonymously. Within the context of this document terms “coupled to” and “coupled with” are also used euphemistically to mean “communicatively coupled with” over a network, where two or more devices are able to exchange data with each other over the network, possibly via one or more intermediary device.
[0075] Moreover, in interpreting both the specification and the claims, all terms should be interpreted in the broadest possible manner consistent with the context. In particular, the terms “comprises” and “comprising” should be interpreted as referring to elements, components, or steps in a non-exclusive manner, indicating that the referenced elements, components, or steps may be present, or utilized, or combined with other elements, components, or steps that are not expressly referenced. Where the specification claims refers to at least one of something selected from the group consisting of A, B, C ….and N, the text should be interpreted as requiring only one element from the group, not A plus N, or B plus N, etc.
[0076] While some embodiments of the present disclosure have been illustrated and described, those are completely exemplary in nature. The disclosure is not limited to the embodiments as elaborated herein only and it would be apparent to those skilled in the art that numerous modifications besides those already described are possible without departing from the inventive concepts herein. All such modifications, changes, variations, substitutions, and equivalents are completely within the scope of the present disclosure. The inventive subject matter, therefore, is not to be restricted except in the protection scope of the appended claims.
