Abstract: Apparatus and methods enable an efficient, low-latency handoff of a communication session, which may be especially effective in a high data rate network. The apparatus and methods provide for a source transceiver module to complete a transmission in-progress while at the same time informing a target transmission module of an end point of the transmission such that data in a shadow buffer of an anchor network function module can be sent to the target transceiver function prior to implementation of the handoff. As such, the apparatus and methods allow for an extremely quick handoff that minimizes use of a backhaul network.

Abstract: Systems and methodologies are described that facilitate maintaining consistent radio-link layer protocol (RLP) sequence numbers in the event of an RLP sequence number reset. An offset can be adjusted upon occurrence of the event to reflect a subsequent expected sequence number. The offset can be added to the RLP sequence numbers such that receiving devices and/or higher layer applications can operate without realizing the sequence number reset. Additionally, the offset can be synchronized among base stations to facilitate operability following handoff of the receiving device.

Abstract: Computer data is transferred between a CDMA radio access network and a GSM core infrastructure using a switch that acts on the CDMA side as a packet data serving node (PDSN) element and on the GSM side as a serving GPRS service node (SGSN) element. Switching message sequences and protocol stacks are disclosed.

Abstract: Method and apparatus for data packet transport in a wireless transmission system supporting broadcast transmissions. A trigger recognized at the transmission node initiates a broadcast transmission, and the resultant set up of a transmission path. A termination trigger then indicates that the transmission node is not serving users desiring the broadcast transmission, and in response the transmission path is shut down. In one embodiment, a multi-cast call, such as a group call, may be transmitted to active users via uni-cast channel(s) or multi-cast channel(s) based on a predetermined criteria, such as number of active users.

Abstract: Method and apparatus for providing provisioning parameters to a mobile device. A short messaging service message is used to send bootstrap data sufficient to establish communication between an Internet Protocol-based server and a mobile device. The mobile device then establishes such communication and the provisioning parameters from the Internet Protocol-based server.

Abstract: A method and apparatus for negotiating capability information for a broadcast service in a communication system. In one embodiment, the generic capabilities are pre-configured in BSC, which provides the generic capability information to MS and to PDSN based on a listing of available BC services and the corresponding capabilities. Another embodiment pre-configures PDSN with the generic capability information. According to still another embodiment, PDSN is pre-configured with the generic capability information, wherein the MS queries the PDSN directly for generic capability information via a PPP connection. In yet another embodiment, the MS queries the PCF, which in turn queries all of the PDSN in the system. The PDSN responsible for the BC responds to the query. Where multiple PDSNs may support the BC, the first to respond using multicast addressing obviates the need for the others to respond.

Abstract: Method and apparatus for data packet transport in a wireless transmission system supporting broadcast transmissions. A multicast tree is built between nodes through neighboring routers. The multicast tree forms a tunnel through which the broadcast content is transmitted. The broadcast message is encapsulated in an Internet Protocol packet for transmission through the multicast tree. At least one multicast tree is formed between the Internet portion of the system and the wireless portion of the system, such as the Access Network. In one embodiment, an external multicast tree is formed between a content source and a packet data service node, and an internal multicast tree is formed between the packet data service node and a packet control function node.
