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.

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.

A wireless communications device is configurable to communicate with either one of two networks over a wireless medium, each of the two networks having a different air interface protocol. Additionally, the wireless device includes stored provisioning information for a set of networks of a first type and can map this first provisioning information into a second format for use with networks of a second type. The device also includes a non-volatile memory for storing default provisioning information so that some information remains available regardless of what is erased from the memory. The default provisioning information is enough to establish a connection over one of the available networks and allow reconstruction of a provisioning list.

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.

The disclosure is directed to an access point in a wireless access network and methods for using an access point. The access point includes a transceiver function and a network function. The network function is configured to route packets between a packet-based network and the transceiver function. The transceiver function is configured to support a wireless connection with an access terminal, and provide protocol translation between the packets and physical frames transported over the wireless connection.

System for creation and transport of multimedia content flows. The system includes a method for transporting a content flow to a wireless access network for broadcast to devices coupled to the wireless access network. The method includes transmitting a request message to add the content flow to the wireless access network, wherein the request message includes a scheduled delivery time. The method also includes receiving a response message indicating that the content flow will be added to the wireless access network, waiting until the scheduled delivery time, and delivering the content flow to the wireless access network.

The disclosed embodiments provide for methods and systems for monitoring a paging channel. In one aspect, a method for monitoring a paging channel includes monitoring a paging channel for a page message at scheduled paging slots, determining that an error has occurred at a given paging slot, and monitoring the paging channel for a re-page message at least one scheduled re-paging slot, where the re-paging slots occur after the given paging slot but before the next scheduled paging slot. In another aspect, a method for monitoring a paging channel includes monitoring a first one of a plurality of paging channels for a page message at scheduled paging slots, determining that an error has occurred at a given paging slot, and monitoring at least a second one of the plurality of paging channels for the page message.

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.
