Abstract: A cellular communication system comprises a core network, a first access network not supporting circuit switched services and a second access network supporting circuit switched services. A user equipment detects that an application using circuit switched communication is initiated and accordingly initiates a reselection from the first to the second access network. The user equipment transmits a location update message to a circuit switch mobile switching center of the core network which in response notifies a mobility management entity for the first access network that the access network reselection has been initiated. In response to the notification the mobility management entity initiates a change of a routing association from being with the first access network to being with the second access network. The invention may e.g. allow improved circuit switched fallback for a 3rd Generation Partnership Project cellular communication system comprising an access network supporting only packet switched services.

Abstract: In a wireless communication system wherein a user equipment (UE) that accesses a cell served by an access point (sometimes known as femtocell) is granted only a limited time period during which to camp on, attach to, or connect to the cell, the communication system permits a user of the UE to anticipate an expiration of the time period and, if desired negotiate an extension of the time period. More particularly, the communication system provides for notification of the UE of the duration of this limited time period and further permits the UE to negotiate an extension of the time period when the UE desires to do so. In the event an extension is requested by the user and granted by the owner/operator, a notification will be sent to the user and the UE may reset a timer.

Abstract: A communication system is provided that implements an inter-technology SRVCC handoff without the need for an SRVCC indicator. A user equipment (UE) establishes a communication session that comprises a voice component in a packet data network. In response to determining to handoff the session to a target network, the communication system determines that the session comprises a voice component based on a call-type identifier, preferably a QoS Class Identifier (QCI), that is associated with a voice call and further determines that a target network is a circuit switched network based on configuration information maintained in association with the target network. In response to determining that the session comprises a voice component, that the target network is a circuit switched network, and, based on a profile of the UE, that the UE is capable of operation in single radio mode, the communication system determines to implement a SRVCC handoff procedure.

Abstract: A communication system that includes a Multimedia Broadcast Multicast Service (MBMS) service provides re-broadcasts of an event to subscribers to the MBMS service. An infrastructure included in the communication system and comprising a server coupled to a RAN controller via a support node receives a first set of MBMS data from an MBMS content provider and conveys the first set of MBMS data along with an associated first Session Description to a subscribed mobile station. The infrastructure then receives a second set of MBMS data from the MBMS content provider, wherein the second set of MBMS data comprises a re-conveyance of the first set of MBMS data, and conveys an MBMS notification along with an associated second Session Description to the mobile station. The mobile station may then determine whether to receive the re-conveyance based on the first and second Session Descriptions.

Abstract: In order to facilitate a handoff of a communication session between a legacy circuit switched network and a packet data network such as a 3GPP LTE, 3GPP2 UMB, or WiMAX network, which communication session is anchored in an IMS Voice Call Continuity Application Server (VCC AS), a Circuit Switched Proxy (CS Proxy) is provided in the packet data network that communicates with a Mobile Switching Center (MSC) of the circuit switched network. The CS Proxy allows the packet data network to communicate with the VCC AS, the MSC to communicate with the packet data network, and the MSC to communicate with the VCC AS via the packet data network, thereby allowing an exchange of handoff-related information between the packet data network and the VCC AS, the packet data network and the circuit switched network, and the circuit switched network and the VCC AS via the packet data network.

Abstract: A communication system provides a Multimedia Broadcast/Multicast Service (MBMS) to a roaming user equipment (UE) by receiving, at a first network, a request from the UE to subscribe to an MBMS service and, in response to receiving the request, conveying to the UE a Temporary Mobile Group Identity (TMGI) that is uniquely associated with the MBMS service and the first network. When the first network receives information associated with a registration of the UE with a second network and further receives MBMS data associated with the MBMS service, the first network conveys the MBMS data and the TMGI to the UE via the second network. By using a TMGI that is unique to the MBMS service and the first network, the UEs subscribed to an MBMS service at the second network ignore a notification conveyed to the UE by the second network, thereby preserving a battery life of such UEs.

Abstract: A wireless communication system (100) is configured to send signaling messages through a cell broadcast service (CBS). CBS message pages used to transport signaling messages are identified by assigned message identifiers. Mobile devices (114) within the communication system (100) recognize the CBS messages transporting signaling messages by the message identifiers and pass the signaling messages to an appropriate application or control program module. The message identifier may be used to specify the application or control program module to process the signaling message. The signaling messages transported by the CBS may be used in controlling a multicasting or broadcasting service. Duplicate copies of the CBS message pages may be transmitted and then buffered at the mobile device (114) as they are received until all parts of the signaling message have been received.

Abstract: A method and apparatus for routing a call to a dual mode mobile station (102) when the dual mode mobile station is in one of a plurality of domains (104, 106) is described. If the mobile station (102) is compatible with the domain (104, 106) in which the mobile station has coverage, then the call is delivered to the domain (104, 106) in which the mobile station has coverage. If the mobile station is in a first domain (102), is registered in a second domain (104) and there is no coverage in the second domain (106), then the call may fail in the first domain (104). If the mobile station is not in the first domain (104), is registered in the second domain (106) and there is coverage in the second domain (106), then the call is delivered to the second domain (106).

Abstract: An apparatus and method for throttling server communications in a communication network. Firstly, priorities are defined by a watcher for particular status events. These priorities are then mapped to a list of status events in an event filter. In response to a change of status event of a presentity, the status event is compared to the list of status events of the event filter. If the comparable status event has an associated higher priority, a notification is sent of the change of status event to the watcher with substantially no delay. If the comparable status notification event has an associated lower priority, the status event is filtered in the event filter, and sent to the watcher, as needed, during a predetermined interval. A unique priority code can be defined for events and/or a maximum delay for sending a notification of an event change can be defined for events.

Abstract: In the present technique of wireless data synchronization, a data synchronization request to wirelessly synchronize data related to the request with a server is intercepted (304). Synchronization information of the data synchronization request to the server is assessed (306) to determine (308) whether the synchronization information corresponds in at least a predetermined way to a predefined condition. The data related to the data synchronization request is synchronized (310) with the server when the synchronization information corresponds in at least the predetermined way to the predefined condition.

Abstract: A Multimedia Broadcast/Multicast Service (MBMS) application server in a packet data communication system produces multiple access control parameters that at least partially identify a storage location of MBMS data and that define when a user equipment may access the stored MBMS data. The multiple access control parameters are then distributed to user equipment (UE) subscribed to the MBMS service. When a subscribed UE fails to receive, or erroneously receives, MBMS data associated with the MBMS service, the subscribed UE uses the distributed access control parameters to determine when and where to access the stored MBMS data.

Abstract: A Multimedia Broadcast/Multicast Service (MBMS) server in a packet data communication system generates and assigns Temporary Mobile Group Identities (TMGIs) to MBMS services, thereby serving as a central repository for the TMGIs. In response to receiving a request to participate in an MBMS service, the MBMS server generates a TMGI. The MBMS server assigns the TMGI to the MBMS service and stores the TMGI in association with information relating to the MBMS service to produce a stored TMGI. The MBMS server further conveys the TMGI to a source of the received request, thereby providing for a distribution of the TMGI to mobile stations subscribed to the MBMS service. The subscribed mobile stations may then use the TMGI to receive data packets associated with the MBMS service.
