Abstract: Systems and techniques are disclosed relating to communications. The systems and techniques involve supporting communications between a base station and a plurality of users by establishing an overhead channel between one of the users and the base station, and transmitting data from said one of the users to the base station on the overhead channel in response to a message having a threshold value related to a loading on the base station by the users. It is emphasized that this abstract is provided to comply with the rules requiring an abstract which will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or the meaning of the claims.

Abstract: Micro-tunnels are used to provide multiple data service sessions to the same mobile node in a wireless communications system. Further, the flexibility of the micro-tunnels optimizes the resources of the system. On request for a da ta service, an encapsulation configuration record is generated. An encapsulatio n header is created in response to the encapsulation configuration. The encapsulation header includes a packet service identifier and a micro-tunnel identifier.

Abstract: An apparatus (102, 104) for transmitting a stream of information bytes, the apparatus (102, 104) includes a mechanism (604, 618, 638) for receiving/transmitting a message specifying a radio link protocol, RLP, round-trip time, RTT, estimate, and a mechanism (604) for conducting an RLP communication session using said RTT estimate to determine negative acknowledgment, NAK, message timing. A first RLP RTT estimate can be established during service negotiation, and is used to determine NAK message timing in a subsequent RLP communication session. Alternatively, a 3-way handshake is performed for generating a first RTT estimate associated with the first RLP communication session, a second RTT estimate, based on the first RTT estimate, associated with a second RLP communication session is established during service negotiation. The second RLP RTT estimate is used to determine NAK message timing in a subsequent RLP communication session.

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 an overhead information for a broadcast service in a wireless communication system via an out-of band transmission. The mobile station is able to contact the content server directly using the out-of-band signaling over a packet data service option. The out-of-band communication allows the content server to update the information without transmitting via an intermediate infrastructure element. In one embodiment, the overhead information includes a service option number corresponding to a set of broadcast parameters, such as those identifying a protocol stack for processing broadcast content.
