摘要： In an embodiment, a server determines to update at least one group session key (GSK) parameter for a given multicast group, the at least one GSK parameter configured to permit encryption, decryption and/or authentication of multicast messaging exchanged between members of the given multicast group during a multicast communication session. The server sends a notification to a plurality of multicast group members of the given multicast group that an update of the at least one GSK parameter for the given multicast group is available. At least one of the multicast group members receives the notification and sends a provisioning request to retrieve the updated at least one GSK parameter, the provisioning request including information specific to the given multicast group member. The server generates and encrypts the updated at least one GSK parameter and sends the encrypted at least one GSK parameter to the at least one multicast group member.

摘要： A user equipment (UE) and an application server exchange data in a wireless communications network. The UE is configured to connect to both a wireless local area network (WLAN) and a wireless wide area network (WWAN). The application server is positioned within the WWAN behind a WWAN firewall. The WLAN includes a WLAN network address translation (NAT) component and firewall such that the UE and the application server do not have a persistent data connection over the WLAN. In an embodiment, the application server can open a WWAN firewall to permit uploads from the UE over the WLAN. In another embodiment, the UE can open the WLAN firewall and/or NAT to permit downloads from the application server over the WLAN. In another embodiment, the application server or UE can upload files to a server outside the WLAN and WWAN firewalls and send a link to the uploaded files for retrieval.

摘要： In an embodiment, an application server receives a request to initiate a group communication session (GCS) over a Wireless Wide Area Network (WWAN) with a communication group. The application server obtains location information of a set of devices participating in the GCS and determines that the GCS can be supported between the set of devices via a Personal Area Network (PAN), after which the application server transitions support for the GCS from the WWAN to the PAN. In another embodiment, an originator begins a periodic broadcast of a local PAN signal announcing the GCS after failing to set-up the GCS via the WWAN. Target device(s) in the communication group receive the local PAN signal, determine not to transmit their own local PAN signal and then convey a session acceptance message to the originator. The GCS is then established between the target device(s) and the originator over the PAN.

摘要： In an embodiment, an SGSN determines whether a local network is configured to support a given service locally. The SGSN receives an Activate PDP Context Request message associated with the given service from a roaming UE and selectively terminates a PDP for the given service within the local network based at least in part upon the determination. In another embodiment, an MME determines whether the local network is configured to support the given service locally. The MME receives a PDN Connectivity Request message associated with the given service from the roaming UE, and selectively terminates an EPS Bearer for the given service within the local network based at least in part upon the determination. In the respective embodiments, the SGSN and/or the MME are configured to ignore HLR settings for PDP termination and/or EPS Bearer termination, respectively, of the UE.

摘要： The disclosure relates to group communications over multimedia broadcast-multicast services (MBMS). An embodiment of the disclosure establishes a first multicast flow and assigns a second multicast flow, wherein the second multicast flow contains signaling and media for at least one group call, and wherein the first multicast flow is configured to send information regarding activity on the second multicast flow. An embodiment of the disclosure monitors a first multicast flow for an announce message regarding a first group call, and upon receipt of the announce message, switches to a second multicast flow that contains signaling and media for the first group call.

摘要： A method and apparatus for performing lawful intercept in a group call is described. A group call for is established and at least one target member device of the group call is identified as corresponding to a subject to be tracked. Call content for communications corresponding to the call is then tracked from the beginning of the call. A query is presented to a law enforcement authority to determine whether the law enforcement authority wishes to receive call data collected before the target joined the call or after the target leaves the call.

摘要： In an embodiment, an application server receives a call message, from an originating user equipment (UE), that is configured to request initiation of a communication session, to be arbitrated by the application server, between the originating UE and at least one target UE. The application server selectively sends, in response to the call message, dummy data to a serving access network of a given UE associated with the communication session in order to facilitate a transition of the given UE to a dedicated-channel state. For example, the application server can selectively send the dummy data based on a size of the call message and/or based on a type of the communication session.
