Abstract: A method and apparatus for providing a service from an application service provider to a client in a communications system including a network proxy describes a first step of defining services provided by the service provider as Extensible Markup Language (XML) metadata. A next step includes defining services desired by the client as XML metadata. A next step includes collecting the XML metadata from the client and service provider. A next step includes comparing the client XML metadata against the service provider XML metadata. A next step includes providing the substantially matched service from the service provider to the client upon the finding of a substantial match between the client metadata and the service provider metadata.

Abstract: A method is provided for on-demand communications in a communication network with support for a plurality of communication units participating in a common communication, which includes multiple signal initiators, each supplying a signal, which are virtually simultaneously conveyed as part of the common communication. At least one example of an on-demand communication includes push to talk. Additionally, a signal initiator is provided, which is adapted to support on-demand communications in a multi-signal initiator environment.

A wireless communication unit such as a mobile station (102), user equipment (202, 302) can move from one site to another site whereupon new identifiers can be setup for the new site. If a serving node associated with the new site is also new, identifiers can be set up for the new site and the new serving node.

Abstract: A communication system distributes the functions of a socket abstraction layer of the prior art between a socket abstraction layer included in an client communication device, such as a mobile subscriber, and a socket abstraction layer in a an agent communication device, such as an infrastructure serving the mobile subscriber. By so distributing the functions of the socket abstraction layer, headers may be reduced in signaling between the client communication device and the corresponding agent communication device as part of call set ups and tear downs and in the exchange of payloads between the client and agent communication devices. By reducing the required headers, overhead is reduced and bandwidth is conserved in communications between the client and agent communication devices, such as in over-the-air communications between a mobile subscriber and an infrastructure serving the mobile subscriber, with resulting increases in system capacity and improvements in system efficiency.

Abstract: A communication system comprising a mobile station and a network implements a persistent packet data control channel that provides for a continuous exchange of control information, such as system information (SI) messages and handoff-related information. The mobile station implements the persistent packet data control channel by mapping the persistent packet data control channel to a packet associated control channel when a packet associated control channel is available and to a virtual associated control channel when a packet associated control channel is not available. The virtual associated control channel allows the mobile station to pass control information to network in the absence of an uplink Temporary Block Flow (TBF).

Abstract: The invention provides for path optimization for routing of a communication session in a network having a plurality of core networks coupled to a plurality of access networks. Both a core network and an access network perform the path optimization by determining a plurality of possible paths to a plurality of target access points to form a target matrix, determining a corresponding route preference factor for each possible path of the target matrix, and selecting, from the target matrix, a possible path having an optimal route preference factor. An overall or complete path, for routing of the communication session, is then determined either by combining the selected possible paths, or by selecting one possible path as a complete path.

Abstract: The present invention provides a method for managing in a mobile subscriber the traffic flow of a communication connection during a cell reselection. The method includes communicating via a communication connection with a first cell, and monitoring communication conditions, while communicating with the first cell. An approximate time is then determined, when conditions associated with the flow of communication via the communication connection with the first cell is consistent with transferring the flow of communication to a communication connection with a second cell. The mobile subscriber then establishes a communication connection with the second cell, while maintaining the communication connection with the first cell.

Abstract: A method (400) and a communication network (110) for operating a cross coding element are described herein. The communication network (110) may detect a condition suggesting a change in encoded protocols between a first endpoint (240) and a second endpoint (250) such as, but not limited to, a call setup, an application requirement, and a handover associated with the first endpoint (240). The first endpoint (240) may operate in accordance with a first encoded protocol whereas the second endpoint (250) may operate in accordance with a second encoded protocol. The communication network (110) may communicate with a cross coding element (230) configured to convert a first encoded protocol signal from the first endpoint (240) to a second encoded signal. The first encoded signal may be encoded by the first encoded protocol, and the second encoded signal may be encoded by the second encoded protocol.

Abstract: A method (400) and a communication network (210) for cross coding between encoded protocols in a communication system (100) are described herein. The communication system (100) provides communication services to a plurality of endpoints. In particular, the communication network (210) provides a cross coding element (330) coupled to receive a first encoded signal from a first endpoints (230) using a first encoded protocol. The communication network (210) converts the first encoded signal within the cross coding element (330) from the first encoded protocol to a second encoded protocol to produce a second encoded signal. The communication network (210) communicates the second encoded signal to a second endpoint (250) using the second encoded protocol.
