20150023252 | METHOD TO USE EXISTING NAS SIGNALING CONNECTION FOR PENDING UPLINK SIGNALING/ DATA AFTER TAU ACCEPT - A method and system to use existing Non-access stratum (NAS) signaling connection for pending uplink signaling/data after Tracking Area Update Procedure (TAU) complete is disclosed. The proposed method handles the EPS Session Management (ESM), Short Message Service (SMS) or voice call or data when a User Equipment (UE) is waiting for TAU accept. The method allows UE to inform the network with specific Information Element (IE) in TAU complete message, so that the network will take the next action. This will help to provide quick services to the user. Using the “CONN REQ TYPE” IE, in TAU complete, to handle all abnormal Cases for Circuit Switches (CS) services/data services in E-UTRAN (Evolved UTRAN) network. | 01-22-2015 |
20150126189 | METHOD AND SYSTEM FOR OPTIMIZING CLOSED SUBSCRIBER GROUP (CSG) SELECTION IN WIRELESS COMMUNICATION - The various embodiments herein provide a method and system for optimizing Closed Subscriber Group (CSG) selection in wireless communication. The method comprising steps of initiating, by a user equipment (UE), a manual CSG selection, verifying if a manual CSG selection request is new, storing a registered public land mobile network (RPLMN) and a corresponding public land mobile network (PLMN) Selection mode if the CSG selection request is new, changing a PLMN selection mode and the CSG selection mode to MANUAL, registering the UE on to a user selected CSG cell, storing one or more parameters associated with the user selected CSG cell if the registration is successful irrespective of CSG cell belonging to RPLMN or different PLMN and selecting the user selected CSG cell using a stored PLMN ID and a CSG ID combination in the current PLMN selection mode during power off and power on. | 05-07-2015 |
20150257037 | METHOD AND DEVICE FOR RETAINING ROBUST HEADER COMPRESSION (ROHC) COMPRESSOR STATE - A method for retaining a Robust Header Compression (ROHC) state in a User Equipment (UE) during switching from a Voice over Long Term Evolution (VoLTE) call to a video call or vice versa is provided. When the VoLTE call is in progress and if a user switches the VoLTE call to the video call, then the RTP header information is sent to an Application Processor (AP) from a Communication Processor (CP). The ROHC compressor continues the compression of the RTP packets using the existing built context for the video call. Further, when the video call is in progress and if the user switches the video call to the VoLTE call, then the RTP header information is sent to the CP from the AP. The ROHC context is reused by exchanging the RTP header information between the AP and the CP. | 09-10-2015 |
