摘要： Binding proxies are used to reduce packet routing delays and call setup delays in a data network made up of a plurality of subnetworks. The binding proxy detects when a mobile device connects to a subnetwork and sends a binding message to various correspondent device(s) in the data network. The binding message contains a care-of-address of the mobile device that allowing the correspondent device(s) to send messages directly to the subnetwork that the mobile device is connected, thereby bypassing a home agent of the mobile device.

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 hosted inter-radio frequency subsystem interface (HIF) maintains a list of affiliated radio frequency subsystems (RFSSs), the list identifies at least one serving RFSS. An affiliation request is transmitted from the HIF to the home RFSS, which is a home RFSS of the group. The HIF receives from the serving RFSS a request to initiate an inter-RFSS group call to the group using HIF addressing. The HIF transmits a request to the home RFSS to initiate the inter-RFSS group call using serving RFSS addressing. A data packet from the home RFSS or the serving RFSS is received at the HIF. Upon receipt, the HIF transmits a copy of the data packet to the serving RFSS if the data packet was received from the home RFSS; otherwise, the HIF transmits a copy of the data packet to the home RFSS if the data packet was received from the serving RFSS.

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.

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： A method and apparatus is provided for dynamically switching mobile stations between point-to-point (PTP) and point-to-multipoint (PTM) operating modes. For example, a particular mobile station can determine whether reception of information over a downlink PTM bearer is inadequate or adequate. Upon determining that the reception of the information over the downlink PTM bearer is inadequate, the particular mobile station can generate and transmit a complaint message to a controller. It can then be determined whether the particular mobile station is to switch between the PTP operating mode and the PTM operating mode. A signal can be processed at the particular mobile station. When the signal is to switch to the PTP operating mode, the particular mobile station can switch from the PTM operating mode to the PTP operating mode and start receiving downlink transmissions over a PTP bearer.
