    摘要: An infrastructure device in a 3GPP compliant system performs a method to allocate MBMS bearers. The 3GPP compliant system includes a RAN partitioned into a plurality MBMS services areas, wherein each MBMS service area has a plurality of pre-established MBMS bearers for transporting media streams. The infrastructure device: receives a request to transmit a media stream to a communication group; selects a set of the MBMS service areas for transporting the media stream; determines an available MBMS bearer in each selected MBMS service area to assign to transport the media stream; and identifies the assigned MBMS bearers to members of the communication group. In addition, a UE performs a method for MBMS service area location update in the 3GPP compliant system. Accordingly, the UE: determines a 3GPP MBMS service area in which the UE is currently located; and identifies the 3GPP MBMS service area to an infrastructure device.

    摘要: Methods for increasing encryption synchronization availability include collecting encryption synchronization data from a first superframe received at a gateway. The encryption synchronization data is for decrypting media in a second superframe also received at the gateway. The encryption synchronization data from the first superframe is used to form a composite encryption synchronization codeword for decrypting media in a third superframe formed by the gateway, wherein the third superframe includes the composite encryption synchronization codeword and at least a portion of the media from the second superframe. The third superframe is sent to a receiving device so that media in the third superframe can be decrypted by the receiving device using the composite encryption synchronization codeword that is included in the same superframe as the media that is being decrypted.

    摘要: An infrastructure device in a 3GPP compliant system performs a method transporting a plurality of media streams over a shared MBMS bearer. The 3GPP compliant system includes a RAN partitioned into a plurality MBMS services areas, wherein each MBMS service area has at least one already existing shared MBMS bearers for transporting the media streams. The infrastructure device: receives a first request to transmit a first media stream to a first communication group; identifies a shared MBMS bearer in a first 3GPP MBMS service area that is already transporting a second media stream to a second communication group; and determines whether the shared MBMS bearer has sufficient capacity to transport both the first media stream and the second media stream simultaneously. When the shared MBMS bearer has sufficient capacity, the infrastructure device simultaneously sends both the first media stream and the second media stream on the shared MBMS bearer.

    摘要: A method and apparatus for extending a virtual channel of a communication area to a user equipment is disclosed. A message including a virtual channel identity and an area identity from the user equipment is received at a call controller. The call controller determines that the virtual channel identity is associated with a communication area and the area identity is associated with an area outside the communication area. The call controller then determines whether a virtual channel extension feature is enabled on the user equipment, and if so, receives data from the user equipment and then distributes the data on the virtual channel.
