Abstract: A method of a terminal and the terminal are provided. The method includes detecting a location area change when a congestion timer is running and one of a general packet radio service (GPRS) update status indicating “GU1 UPDATED,” a mobility management (MM) update status indicating “U1 UPDATED,” and an evolved packet system “EPS” update status indicating “EU1 UPDATED” is indicated; adaptively changing the GPRS update status to “GU2 NOT UPDATED,” the MM update status to “U2 NOT UPDATED,” and the EPS update status to “EU2 NOT UPDATED”; and entering a state of “GMM-REGISTERED.ATTEMPTING-TO-UPDATE,” “MM IDLE, ATTEMPTING TO UPDATE,” or “EMM-REGISTERED.ATTEMPTING-TO-UPDATE,” in accordance with one of “GU2 NOT UPDATED,” “U2 NOT UPDATED,” and “EU2 NOT UPDATED.”

Abstract: A method for connecting to a Registered Public Land Mobile Network (RPLMN) after receiving an accept message with limited service from a user selected CSG cell, which is associated to a different PLMN than the RPLMN during manual CSG selection mode is disclosed. The method includes connecting to the RPLMN based on the availability of the user selected CSG cell in UTRAN. If the user selected CSG cell is not available in UTRAN, then the method includes connecting to the RPLMN by the UE using the stored duplicate value of the RPLMN. If the user selected CSG cell is available in UTRAN, then the method includes sending an ATTACH request to the user selected CSG cell without disabling the EUTRA capabilities. If the ATTACH request is failed, then the method includes connecting to the RPLMN using the stored duplicate value of the RPLMN.

Abstract: A method of controlling a timer in a User Equipment (UE) is provided. The method includes determining, by a controller in the UE, whether a current international mobile subscriber identity (IMSI) matches a stored IMSI if the UE is powered ON, activating, by the controller, the timer if the current IMSI matches the stored IMSI; and stopping the timer if the current IMSI does not match the stored IMSI.

Abstract: A method for handling checksum error in uplink data compression (UDC) in a wireless communication system includes: detecting, by user equipment (UE), a checksum failure; automatically controlling, by the UE, generation of a number of compressed protocol data units (PDUs) available for transmission at a Packet Data Convergence Protocol (PDCP) based on a package formation rate (PFT); and transmitting, by the UE, a number of compressed PDUs.

Abstract: A method and system for minimizing delay in circuit-switched fallback (CSFB) procedure is disclosed. The disclosed method provides two different approaches for optimizing the delay during the CSFB procedure. In the first approach, user equipment (UE) receives a Location Area Identifier (LAI along with the Radio Access Technology (RAT) information from the network (LTE network). The UE uses the received RAT information from the network for switching to the target Radio Access Network (RAN) without informing to the LTE network. In another approach, the UE obtains the RAT information by performing a background scan in idle mode, when the UE receives LAI without RAT information from the network.

Abstract: A method and user equipment for handling a Public Land Mobile Network (PLMN) selection in a mobile communication network is provided. The method includes obtaining, by a User Equipment (UE), a PLMN list of one or more Radio Access Technologies (RATs) comprising a list of available PLMNs, when the UE performs a Manual Closed Subscriber Group (CSG) selection, initiating a PLMN list validation timer, and reusing the previously obtained PLMN list, when at least one predefined event is triggered and the PLMN list validation timer is running. The at least one predefined event comprises at least one of Home Public Land Mobile Network (HPLMN) timer expiration, a manual PLMN selection, the manual CSG selection, and autonomous CSG selection.

Abstract: Disclosed herein is a method for UDC based communication in a wireless communication system. The method includes detecting a handover event or a re-establishment event for a UDC bearer, between a UE and a network. The method further includes performing a first determining operation for determining whether a PDCP status report is received by the UE from the network. Thereafter, the method includes transmitting uncompressed data packets until the PDCP status report is received by the UE. The method further includes performing a second determining operation for determining whether a PDCP timer associated with a reordering window of the PDCP layer is running or stopped. The method further includes transmitting compressed data packets based on a result of the first or second determination operation.
