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 (110) coupled to a plurality of access networks (120). 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. The route preference factor, for each possible path, is determined based upon various routing variables, such as quality of service, bandwidth for the communication session, route complexity, interconnect cost, routing cost; resource loading, resource availability, and operator preference for traffic biasing.
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.
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. The method further includes routing the flow of the communication from the communication connection with the first cell to the communication connection with the second cell, and releasing by the mobile subscriber the communication connection with the first cell, proximate the time that the flow of communication is routed from the communication connection with the first cell to the communication connection with the second cell.
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.

Abstract:
A. method and system of generating neighbor cell lists in a cellular environment having a first cell (cell D) and a plurality of neighbor cells (cells C, E, F, and G). The first cell and the neighbor cells each include a plurality of designated active controllers associated therewith. In one embodiment, one of the controllers (RNC3) in the first cell is designated as the active controller for the first cell, a first neighbor list of the active controllers (RNC1, RNC3, RNC4, and RNC 4, respectively) for the neighbor cells is generated, and, upon a change in active status of any of the neighboring active controllers, a second neighbor list of the active controllers (RNC2, RNC4, RNC4, and RNC4, respectively) for the neighbor cells is generated. The lists are generated in accordance with a database of controllers linkable with the designated active controllcr.
