Abstract:
A communication system (100) that includes a Multimedia Broadcast Multicast Service (MBMS) service provides re-broadcasts of an event to subscribers (102-104) to the MBMS service. An infrastructure (124) included in the communication system and comprising a server (118) coupled to a RAN controller (114) via a support node (116) receives a first set of MBMS data from an MBMS content provider (127) and conveys the first set of MBMS data along with an associated first Session Description to a subscribed mobile station (102-104). 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:
A Multimedia Broadcast/Multicast Service (MBMS) application server (122) in a packet data communication system (100) 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) (102) 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 (122) in a packet data communication system (100) 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 (400). 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 (102-104) subscribed to the MBMS service. The subscribed mobile stations may then use the TMGI to receive data packets associated with the MBMS service.
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:
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 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 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.
