Abstract: A method and a wireless transmit/receive unit perform a handoff to a target base station having enhanced capabilities. A dual mode manager triggers a capabilities query for information regarding enhanced capability of the target base station, wherein the enhanced capability includes transmission in accordance with a high speed data mode. A generator sends the query to a server connected to the Internet via a first base station not having enhanced capability. The dual mode manager receives from the server via the first base station information regarding the enhanced capability. A handoff to the target base station is initiated by the dual mode manager on a condition that the received information indicates that the target base station has enhanced capability. The dual mode manager deactivates a first mode of operation for communication with the first base station and activates the high speed data mode for communication with the target base station.

Abstract: An improved data communication network including a wireless link for accessing, from an end user machine, objects in a selected web page retrievable from an Internet server by means of suitable request messages is described. The wireless link includes a subscriber unit coupled to the end user machine and a base station coupled to the server. Web page data packets retrieved from the server with the use of the request messages are intercepted and locally stored in a gateway unit on the base station side of the wireless link. The gateway unit generates, from the retrieved web page data packets, additional request messages suitable for retrieving, from the server, object data packets corresponding to the objects on the selected web page. Such retrieved object data packets are also stored in the gateway unit.

Abstract: An improved arrangement is described for signaling enhanced capabilities of a wireless data communication system to a dual-mode wireless handset seeking access to such capabilities and normally operating in a first (non-enhanced) mode. The arrangement, which is especially advantageous for ascertaining operating mode capabilities of a new cellsite to which the handset is being handed off from an existing cellsite, includes a separate capabilities server that is associated with the system and contains a data base populated with information indicative of such capabilities. The handset generates a suitable query message which is transmitted to the data base in the first mode after the handoff to retrieve the capability information for the new cellsite location. The handset is switched from the first mode to the second (enhanced) mode for post-handoff operation if the retrieved capability information indicates that the new cellsite is capable of operation in the enhanced mode.

Abstract: Session services are employed in a networked computing environment to apply specific processing to an exchange of data between processes. In a wireless communication network, a single wireless link is typically shared among multiple users through wireless channels, which are allocated and switched among the users on a demand basis. Packets sent over the wireless link need to be signaled and tagged accordingly to initiate and employ the session service for the intended packets which comprise the flow. A method for identifying and applying session services to a wireless link includes identifying a packet flow over the wireless link corresponding to a received message by employing a flow identifier and filter. The packet flow corresponds to a session, and is mapped to at least one session service. The mapped session service is then applied to the received message.

Abstract: A dual split-TCP connection for improving throughput in a data transmission system containing a wireless link is described. A pair of gateways are individually associated with a subscriber unit and a base station on opposite sides of the wireless link. The gateways respectively form spaced TCP proxy terminations for a pair of terminal machines, such as an end user machine and a server, between which data packets are exchanged over the system. Transmission over the wireless link itself employs an optimized wireless protocol or another non-TCP protocol such as UDP. Such elimination of the use of TCP over the wireless link minimizes delays attributable, e. g., to false readings of congestion on such link and the consequent unnecessary triggering of TCP congestion control/slow start mechanisms.
