Abstract:
A method for performing a cell search in a multi-subscription device is provided. The method includes estimating, by a first subscriber identity module (SIM) of multiple SIMs of the multi-subscription device, search time information required for identifying one cell and margin time information for cell search, where the first SIM is associated with a first radio access technology (RAT); obtaining a discontinuous reception (DRX) period of a second SIM associated with a second RAT in the multi-subscription device; determining a number of cells to be searched during the DRX period based on the estimated information; performing a measurement for one or more cells to be searched based on the number of the cells; ranking the one or more cells based on the measurement; and initiating a cell search on one or more cells having a highest signal strength during the DRX period.
Abstract:
Methods and apparatuses are provided for providing service recovery at a user equipment (UE) of a mobile communication network. The UE establishes a call in a first public land mobile network (PLMN). A handover zone of the first PLMN and a second PLMN is entered. The second PLMN is in a forbidden PLMN list of the UE. The UE receives a dedicated message with an indication of the second PLMN. The second PLMN is removed from the forbidden PLMN list. The UE performs registration with the second PLMN so that services of the second PLMN are available to the UE.
Abstract:
A method and system for power saving of a remote device determines whether to offload the application to a cloud server by comparing the cost of computing the application data in the remote device to that of computing the same application data in a cloud server. If the former cost is greater, then the remote device offloads the application to a cloud server. The method takes into the account the parameters such as distance between the remote device and the access network, the power required to transmit the application data from remote device to the cloud server for calculating the power required for computing the application data in the cloud server.
Abstract:
The present disclosure provides a method and apparatus of handling in-device co-existence interference in a wireless communication environment. In one embodiment, a method includes detecting in-device co-existence interference between a LTE module and an ISM module in user equipment. The method further includes identifying subframes and corresponding HARQ processes in a set of subframes allocated to the LTE module which are affected by the ISM module operation. Additionally, the method includes reserving the remaining subframes and corresponding HARQ processes in the set of subframes for the LTE module operation. Furthermore, the method includes indicating to a base station that the remaining subframes and the corresponding HARQ processes are reserved for the LTE module operation to resolve the in-device co-existence interference. Moreover, the method includes receiving scheduling pattern indicating subframes and corresponding HARQ processes reserved for the LTE operation or derived DRX parameters from the base station based on the indication.
Abstract:
Methods and apparatuses are provided for providing integrity protection in a dual subscriber identity module (SIM) dual standby (DSDS) device. A first message is received on a first SIM of the DSDS device before a radio resource of the DSDS device is tuned away from the first SIM to a second SIM by performing a tune-away procedure. A second message is received after completion of the tune-away procedure. The second message is validated. It is determined whether a first payload of the first message matches a second payload of the second message, when the first message and the second message have a same message sequence number. It is determined that the second message is a duplicate message, when the first payload matches the second payload.
Abstract:
A method for reducing consumption of battery power of User Equipment (UE) during inter-frequency cell detection in a Heterogeneous Network (HetNet) is provided. The method includes receiving an indication from a serving cell operating on a first frequency layer about presence of a beacon signal transmission on the first frequency layer from a non-serving cell, an actual data transmission and reception of the non-serving cell occurs on a second frequency layer, determining whether the indication satisfies at least one triggering condition to initiate signal scanning on the first frequency layer for identifying the beacon signal transmission from the non-serving cell, scanning, when the received indication satisfies the triggering condition, the first frequency layer for identifying any beacon signal, decoding the beacon signal from the non-serving cell, and receiving assistance information from the serving cell to facilitate identification of the non-serving cell transmitting the beacon signals on the first frequency layer.

Abstract:
A method and system to improve emergency call continuity by allowing inbound mobility towards non-member CSG cells is disclosed. The method enables the UE to detect an emergency call. Then the UE initiates an autonomous search procedure by itself, without need for network to configure the UE for proximity reporting. The method enables the UE to use non-member CSG cells for continuity of emergency calls. The method also enables the UE to confirm emergency call handling support provided by the target CSG cell before initiating handover.
Abstract:
Methods and apparatus for supporting emergency communications are provided. A method for a Radio Access Network (RAN) serving at least one Core Network (CN) to support emergency communications of a User Equipment (UE) includes determining whether at least one CN in a shared network environment supports emergency communications, if it is determined that the at least one CN in the shared network environment supports emergency communications, transmitting an emergency call support indication to the UE indicating that emergency communications are supported, receiving a request for emergency communications from the UE, and routing the request for emergency communications to another CN that supports emergency communications in the shared network environment, if a given CN does not support emergency communications.
