Abstract: A method and system configures proximity indication in a wireless device as part of a network handover procedure to handover the wireless device from a first radio access network (RAN) using a radio access technology (RAT) to a second RAN using a different RAT. The first RAN may use third generation (3G) wireless technology to initiate a process to hand over a wireless device to the second RAN, which utilizes long term evolution (LTE) technology. As part of the handover process, the second RAN generates a handover command message that additionally includes proximity indication configuration information to enable the wireless device to configure proximity indication reporting. The handover command message is sent through the first RAN to the wireless device, where the handover command message is utilized to configure proximity indication reporting and to perform the handover from the first RAN to the second RAN.

Abstract: A mobile device initiates an RRC connection reestablishment procedure or a cell update procedure for an emergency call after experiencing a failure condition in an LTE network environment. The mobile device establishes an RRC connection with an acceptable cell to originate an emergency call. The mobile device detects a failure condition, such as a radio link failure, which disrupts the RRC connection. The mobile device searches for available cells that it may reestablish the RRC connection with, but can only find acceptable cells. The mobile device may initiate an RRC connection reestablishment procedure with an acceptable cell. The mobile device may also only attempt to reestablish the RRC connection with a cell that is part of a PLMN that the original acceptable cell was also a part of. The mobile device may also enter an RRC_IDLE mode upon detecting a failure condition.

Abstract: A mobile communications device with a wireless module and a controller module is provided. The wireless module performs wireless transmissions and receptions to and from a cellular station. The controller module receives a detachment request message comprising a detachment cause from the cellular station via the wireless module, and determines whether the detachment cause indicates unauthorized membership of a closed subscriber group (CSG) supported by the cellular station. Also, the controller module determines whether the cellular station is a non-CSG cell in response to the detachment cause indicating unauthorized membership of the CSG supported by the cellular station, and keeps an allowed CSG list unmodified in response to the cellular station being a non-CSG cell.

Abstract: The techniques introduced herein provide a system and method for determining whether an inter-RAT handover is an SRVCC handover, and for performing the subsequent SRVCC handover. The techniques include receiving a handover command message that does not include SRVCC related information elements, for example “RAB info to replace,” but continuing with an SRVCC handover using a circuit-switched RAB provided in the information for setup. The techniques also include receiving a handover command message that does include SRVCC related information elements and performing the SRVCC handover by an alternative method.
