A method () and apparatus () facilitate a session handover between a first site and a second site. A wireless communication unit such as a mobile station (), user equipment () 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.

Inter-network handover in a packet radio system

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.

Method and apparatus for transmitting data in a communication system

To address the need for a dispatch mobile () to more quickly make a call, in the preferred embodiment of the present invention those remote units operating in a dispatch mode () will receive a first slot cycle, while those remote units not operating in a dispatch mode () will receive a second slot cycle. The second slot cycle is greater than the first slot cycle, so that those remote units operating in dispatch mode () will 'wake up' during the slot cycle normally utilized for interconnect calls. Because shorter slot cycles are utilized for remote units operating in dispatch mode (), the time it takes to make a dispatch call is greatly reduced. Additionally the minimum slot cycle duration typically used for standard calls remains unchanged, greatly conserving battery life.

Slot cycle assignment within a communication system

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).

Method and apparatus for transmission of control data in a packet data communication system

The present invention provides a method for routing data from a service request in a communication system. A context is transferred from a packet data gateway, such as a Serving GPRS (GSM Packet Radio Service) Support Node (SGSN), to a Base Station System (BSS) coupled thereto. The context specifies where data for this user should be sent. The service request is received at the BSS and includes data. The data from the service request is routed to an appropriate location, based at least in part upon the context.

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. 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.

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.
