Appl. No.:

10/068445

Inventors:

Stephen Spear - Skokie IL
Sanjay Gupta - Lakewood IL
Richard Corrigan - San Diego CA

Assignee:

Motorola, Inc. - Schaumburg IL

International Classification:

H04L 1228

US Classification:

370331, 370401

Abstract:

A method of routing control information and bearer traffic in a packet network. When a wireless communication device has established a connection in a coverage area serviced by an Access Network Controller (ANC) and a Serving Node and roams into an area serviced by a new ANC and a new Serving Node, the present invention routes control information to and from the device through the anchor Serving Node (Serving Node through which the connection was established). Bearer traffic is routed to and from the device through the ANC and Serving Node serving the area in which the wireless communication device is located.

US Classification:

4554351, 455433, 4554122, 370355

Abstract:

A method () and a wireless device () for establishing a communication interface for a communication session are described herein. In a communication system, a wireless device () may receive presence information associated with a first party. Operated by a second party, the wireless device () may generate a notification to alert the second party. The notification may correspond to the presence information associated with the first party. Based on the presence information, the wireless device () may provide the communication interface for the communication session between the first and second parties.

Assignee:

Motorola, Inc. - Schaumburg IL

International Classification:

H04Q 7/00

US Classification:

370328, 370338, 370401, 4554321

Abstract:

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.

Appl. No.:

10/721542

Inventors:

Stephen L. Spear - Skokie IL, US
Mark E. Pecen - Palatine IL, US
Sanjay Gupta - Lakewood IL, US

Assignee:

Motorola, Inc. - Schaumburg IL

International Classification:

H04J 3/00
H04J 3/12

US Classification:

370336, 370345, 370522

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).
