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.

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.

An apparatus and method for performing lawful intercept in group calls is described herein. When a group call is established having a monitoring target as a member, a monitoring component obtains signaling, location, and data related to the monitoring target, correlates this information, and provides it to a call intercept component.

In an embodiment, a mobile communications device (MCD) is positioned within an internal network that is separated from an external network by network address translation (NAT) and/or a firewall. The MCD establishes settings with the NAT and/or firewall by which the MCD can be contacted through from the external network. The settings are configured to be disabled by the NAT and/or firewall after a threshold period of traffic inactivity. An application server receives information associated with the settings, and instructs an assisting application server (AAS) within the internal network to transmit keep-alive packets on behalf of the MCD so as to maintain the settings for the MCD. The AAS receives the instructions from the application server, and instructs an assisting wireless communications device (WCD) within the internal network to transmit keep-alive packets on behalf of the MCD. The WCD then transmits the keep-alive packets in accordance with the instructions.

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.

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.

In an embodiment, a user equipment (UE) determines that a current serving network is associated with a network support zone of a given type, wherein network support zones of different types are characterized by different levels of support for a multimedia client application configured to manage server-arbitrated communication sessions at the UE. The UE loads zone-specific network procedures for supporting the multimedia client application within the network support zone of the given type, and then executes the zone-specific network procedures at the UE. In another embodiment, an application server determines that the current serving network of the UE is associated with the network support zone of the given type. The application server selects zone-specific network parameters and/or features based on the determination, and then interacts with the multimedia client application within the network support zone of the given type with the selected zone-specific network parameters and/or features.
