Patent number: 8867566Abstract: Embodiments of the invention disclose header compression within a wireless communications network. In an example, the method includes establishing, between an access network and an access terminal, a flow identifier (ID) and mapping protocol to support header compression for packets sent to the access network from the access terminal and intended for an application server. The mapping protocol can be configured to convert packets including the flow ID into packets that conform with a given addressing protocol for routing to the application server. The access terminal sends and the access network receives a first packet of a stream of packets. The first packet includes the flow ID and is in a compressed format compared to that of the same packet conforming with the given addressing protocol. The access network converts the received first packet into a routing packet based on the mapping protocol that conforms with the given addressing protocol.Type: GrantFiled: August 20, 2008Date of Patent: October 21, 2014Assignee: QUALCOMM IncorporatedInventors: Harleen K.

Patent number: 8867545Abstract: A method of providing information regarding an Ethernet frame, within the Ethernet preamble of the Ethernet frame, comprises inserting into the Ethernet preamble an inter-line-card header that includes a start control character, a version number, a parity bit, a source port, a destination port, and a forwarding domain entry; and preserving said inter-line-card header, inside of said Ethernet preamble, in a Media Access Control (MAC) sub-layer in said Ethernet frame. The method may include a step of selecting the decoding format for the inter-line-card header corresponding to the version number and/or forwarding other Ethernet frames according to additional forwarding information provided by the forwarding domain entry. The inter-line-card header may be preserved in the MAC sub-layer by keeping the Ethernet preamble at the beginning of an Ethernet frame received over an Ethernet backplane, and passing the combined preamble and associated Ethernet frame to an inter-line-card header processing module.Type: GrantFiled: September 25, 2012Date of Patent: October 21, 2014Assignee: Accedian Networks Inc.Inventors: Yanick Viens, Steve Rochon

Patent number: 8861384Abstract: In geographical areas with incomplete coverage of Time Division Synchronous Code Division Multiple Access (TD-SCDMA) networks, it may be beneficial for a multimode User Equipment (UE) to handover to a Global System for Mobile Communications (GSM) network. Before handover, a multimode UE may receive an indication from a serving TD-SCDMA cell to enter a Discontinuous Reception (DRX) mode and perform measurement on a nearby GSM cell. After measurement, the UE receives a grant from the serving TD-SCDMA cell allowing the UE to transmit a measurement report to the serving TD-SCDMA cell. The TD-SCDMA cell may use the measurement report to determine if the multimode UE should handover to the GSM cell.Type: GrantFiled: September 17, 2010Date of Patent: October 14, 2014Assignee: QUALCOMM IncorporatedInventors: Tom Chin, Guangming Shi, Kuo-Chun Lee
