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: Methods and User Equipment (UE) for managing IMS call over LTE in SRVCC area are provided. The method may include detecting, by an IMS client, that the IMS call over LTE is in an alert state, and a Radio Resource Control (RRC) reconfiguration cells are configured for the IMS call over LTE. Further, the method may include initiating by the IMS client a timer with a value less than a data inactivity timer value from a network entity. Further, the method may include detecting by IMS client that the timer has expired before establishing the IMS call over LTE and restarting by the IMS client the timer. Furthermore, the method may include sending by the IMS client a Session Initiation Protocol (SIP) message to the network entity.

Abstract: A method for handling an ATTACH reject message with packet radio service mobility management reject cause number (#14 cause) at a user equipment (UE) is provided. The method includes receiving, at the UE, an ATTACH accept message for a network service on a public land mobile network (PLMN) from a first network entity, wherein the PLMN is in a “forbidden PLMNs for general packet radio service (GPRS) service” list, detecting, by the UE, that the UE's evolved universal terrestrial radio access (E-UTRA) capability is disabled, and enabling, by the UE, the UE's E-UTRA capability and removing the PLMN from the “forbidden PLMNs for GPRS service” list.
