Abstract: A scheme for managing security key architecture in a network environment where a user equipment (UE) device can engage in multiple security contexts depending on the access technology. In one embodiment, when multiple security contexts are engaged and different sets of authentication vectors are created, an adapter component of the UE device manages potential interference that may be caused among the different sets of the authentication vectors as to where they are stored and which authentication vectors are used for service handovers.

Abstract: A system and method allows for providing emergency service, whether the service is full or limited, to wireless devices using non-IMS packet traffic based methods or Access Stratum/Non-Access Stratum (AS/NAS) signalling based methods. To do so, a system and method for utilizing a Packetized Emergency Message (PEM) is provided.

Abstract: A method of operating a mobile communication device in a mobile telecommunication network, the method comprising the steps of the mobile communication device: receiving a non integrity-protected message with a parameter value included therein to be implemented on the mobile communication device; using a predetermined value stored on the mobile communication device instead of the parameter value received.

Abstract: Methods and apparatus for mobile voice service management are described. An example method includes receiving a mobile network request for registering with a mobile network and responsive to the mobile network request, sending a response including an area identity list and an identifier indicating whether an area identified in the tracking area identity list supports a service.

Abstract: There is discussed a method of selecting an access domain for receiving a speech and/or video call at a mobile station of a mobile communications network in which calls are routed via a central service control common to a plurality of access domains. The method comprises the central service control transmitting an invite to establish a call to the terminating mobile station; the mobile station deciding on an access domain for receiving the call taking into account the capabilities of the local access network, and transmitting the selected access domain to the central service control; and establishing the call in accordance with the selected access domain.

Abstract: Methods and apparatus to manage voice service in evolved packet systems are disclosed. An example method in a User Equipment (UE) with a first indicator related to voice services in an Evolved Packet System (EPS) comprises receiving a Non Access Stratum (NAS) protocol response message with a second indicator and responsive to at least one of the first indicator or the second indicator, determining availability of voice services over IP Multimedia Subsystem (IMS) in at least one of long term evolution (LTE) or global system for mobile communications edge radio access network (GERAN)/universal mobile telecommunications system terrestrial radio access network(UTRAN).

Abstract: Methods and apparatus to manage voice service in evolved packet systems are disclosed. An example in a UE with a first indicator related to voice services in an Evolved Packet System (EPS) includes receiving a first Non Access Stratum (NAS) protocol response message with a second indicator and responsive to at least one of the first indicator or the second indicator, cause the UE to select to another radio access technology (RAT).

Abstract: Methods and apparatus to manage voice service in evolved packet systems are disclosed. An example method in a user equipment (UE) with a first indicator related to voice services in an Evolved Packet System (EPS) comprises receiving a Non Access Stratum (NAS) protocol response message with a second indicator and responsive to at least one of the first indicator or the second indicator, sending a notification that voice services are not currently able to be provided.

Abstract: In a communications network having a first network cell and an associated access device, a method for enabling user equipment (UE) to obtain a service unavailable through the first network cell includes receiving a request for the UE to access the service, identifying the radio coverage of a second network cell, and when the radio coverage of the first network cell is within the radio coverage of the second network cell, directing the UE to the second network cell without requesting measurement data from the UE.

Abstract: A method in user equipment (UE) associated with a first network cell in a wireless telecommunications system includes performing idle mode measurements of one or more network cells other than the first network cell when the UE is operating in an idle mode, receiving a request to access a first service unavailable through the first network cell, communicating with an access device associated with the first network cell based on results of the idle mode measurements, receiving from the access device an identification of a second network cell, and accessing the first service through the second network cell.

Abstract: A method performed by an access device of a first network cell in a communications network for enabling user equipment (UE) to obtain a service unavailable through the first network cell includes receiving a request for the UE to access the service, receiving identification of a location area (LA) in which the UE is registered, identifying a second network cell providing the service in the LA in which the UE is registered, and transmitting the identification of the second network cell to the UE.

Abstract: A method performed by user equipment (UE) includes receiving a request to access a service unavailable through a first network cell associated with the UE, and receiving a message from an access device associated with the first network cell, wherein the message identifies a plurality of second network cells providing the service.

Abstract: A method performed by user equipment (UE) includes receiving a request to access a service unavailable through a first network cell associated with the UE and informing a second network cell that the UE is requesting to obtain the service unavailable through the first network cell. The request may be received from a user of the UE or may be a paging message.

Abstract: In an access device associated with a first network cell, a method for enabling user equipment (UE) to obtain a service unavailable through the first network cell includes receiving a request for the UE to access the service, and identifying, in a message to the UE, a plurality of second network cells providing the service.

Abstract: A user equipment (UE) is provided. The UE comprises a processor configured to receive a broadcast control channel (BCCH) comprising a first indication that a restricted access to a closed subscriber group has been changed and to initiate a signaling procedure based on the first indication.

Abstract: A user agent (UA), core network (CN) device, and method for a circuit switched (CS) fallback service in an evolved packet system (EPS). In one embodiment, the UA or CN includes a protocol layer having a non-access stratum (NAS). A processor of the UA or CN is configured to promote the NAS to process an EXTENDED SERVICE REQUEST having a service type with a decode value. The decode value identifies an EPS-defined radio resource control (RRC) establishment cause (EC).

Abstract: A method of operating a communication system is provided. The communication system comprises a NetWork (NW) and User Equipment (UE), a Non Access Stratum (NAS) via which the NW and UE communicate with each other, and an Access Stratum (AS) providing a physical connection to enable the NAS communication between the NW and UE to be achieved, the physical connection including a wireless radio link to the UE. The method includes sending information from the NW to the UE to determine at least one action of the UE in response to a failure of a radio link to the UE, detecting a Radio Link Failure (RLF), in response to the detecting of the RLF, deciding on an action to be performed by the UE according to the received information, and performing, by the UE, the decided action.

Abstract: A mobile communications method and system for signalling information between a mobile terminal and a network element of a mobile communications network. The mobile terminal transmits information relating to the desirability and/or possibility to support Voice Call Continuity (VCC), to the network element during a communication, and the network element receives the information from the mobile terminal to use the information as a basis for deciding whether or not to anchor a call of the mobile terminal.
