Patent number: 10075182Abstract: Methods and apparatus related to message compression/decompression are described. A compressed message is generated by indicating what changes are to be made to a previous message to produce the message sought to be transmitted. The required change, in the form of at least one command and corresponding parameter, is transmitted as a compressed version of the message being communicated. This approach takes advantage of the fact that messages sent over time often include much of the same message content and only one or a few fields may have changed. The techniques are general and involve including a command in the compressed message along with at least one parameter. The command indicates processing to be performed on a previous message to generate the uncompressed message. The parameter may be, e.g., data to be inserted into the previous message or specify a location in the previous message where the change is to be made.Type: GrantFiled: October 13, 2006Date of Patent: September 11, 2018Assignee: QUALCOMM IncorporatedInventors: Vincent Park, George Tsirtsis, Hesham Soliman

Patent number: 9736752Abstract: Methods and apparatus for routing messages between an end node and an access node via another access node are described. Physical layer identification information is used when identifying a remote, e.g., adjacent, access node as a message destination. Thus, when a connection identifier based on one or more physical layer identifiers is available to a wireless terminal, e.g., from one or more downlink signals received from a destination access node, the wireless terminal can use the connection identifier corresponding to the destination node to route a message via an access node with which it has an established uplink connection. Such connection identifier information can be used even when other addressing information, e.g., network layer address information, associated with the destination access node, may not be available to the wireless terminal.Type: GrantFiled: December 22, 2005Date of Patent: August 15, 2017Assignee: QUALCOMM IncorporatedInventors: Rajiv Laroia, Pablo Anigstein, Vladimir Parizhsky, Murari Srinivasan, George Tsirtsis

Patent number: 8681683Abstract: Providing for inter-system idle mobility management for independent mobile networks is described herein. By way of example, registration of multiple mobile IP (MIP) addresses to a mobile device can be utilized to facilitate inter-system device tracking. An Internet Protocol (IP) home agent that serves the mobile device can associate the MIPs with a home IP address of the mobile device. When communication is received for the home address, device paging can be initiated by utilizing at least a plurality of the MIPs bound to the home address. A mobile device response can provide a current active network address, and the received communication can be delivered via such active network address. As disclosed herein, the mobile device can switch attachment among the networks without signaling such networks, based on the multiple address bindings. Accordingly, significant power reduction can be afforded to mobile devices in idle mode.Type: GrantFiled: May 30, 2008Date of Patent: March 25, 2014Assignee: QUALCOMM IncorporatedInventors: Gerardo Giaretta, George Tsirtsis, Kalle I.

Patent number: 8619995Abstract: Methods and apparatus for generating, communicating, and/or using sets of addresses corresponding to a communications device are described. A first communications device generates, from a public key and a random number, both a first address and a second address. The generated address pair is communicated to a second communications device along with proof of ownership information regarding the address pair via an address signaling message such as a binding update message. The second communications device processes the received address signaling message and determines address pair validity and/or address pair ownership information. The first address may be associated with a first network, e.g., an unsecure WAN network, while the second address may be associated with a second network, e.g., a secure peer to peer network. Decisions on switching between using the first address to using the second address may be based on address validity and/or address ownership determinations.Type: GrantFiled: January 28, 2009Date of Patent: December 31, 2013Assignee: QUALCOMM IncorporatedInventors: Wassim Michel Haddad, George Tsirtsis, Vincent D.
