The present invention provides a method involving at least one mobile node and a heterogeneous network comprising a plurality of access nodes. The method includes transferring event context information associated with a mobile node from a first access node to a second access node.

Event context transfer in a heterogeneous communication system

The present invention provides a method involving at least one mobile node and a heterogeneous network comprising a plurality of access nodes. One embodiment of the method includes providing at least one first message including information indicative of a selected access node. The access node is selected to provide command services to the at least one mobile node.

Selecting a command node in a heterogeneous communication system

A method is provided for triggering migration of call session state information. The method includes determining whether to migrate a network access agent associated with an access terminal in a wireless communication system based on at least one of mobility information associated with the access terminal and status information associated with the wireless communication system.

Triggering migration of a network access agent associated with an access terminal

The present invention provides a method of route optimization. The method may include obtaining a packet associated with a first address associated, by a home agent, with a first mobile unit and routing the packet to a second address associated with a second mobile unit along a forward link of a communication path that bypasses the home agent.

Route optimization at a packet data switch node

The present invention provides a method for encrypting data for transmission over a wireless link. The method includes encrypting at least one block of data, at an air-interface application layer, using an encryption algorithm that receives a cryptosynch as input. The value of the cryptosynch is based on an order of the at least one block of data relative to other blocks of data. The value of the cryptosynch is recoverable by a receiver based on the ordering of the ordering of the blocks of data. The at least one encrypted block of data is transmitted to a receiver that is operable to preserve the order of the at least one block of data relative to the other blocks of data.

Air-interface application layer security for wireless networks

One method includes setting up an authenticated communication session between a mobile terminal and a first core data network. The method includes acquiring, at the first core data network, supplementary access data usable by the mobile terminal to set up a non-authenticated communication session with a second data network and then, transmitting the supplementary access data from the first core data network to the mobile terminal. The second data network is accessible to the mobile terminal.

Accessing networks for limited purposes

The packet-forwarding for proxy mobile IP, in accordance with various embodiments, includes registering a mobile access terminal (AT) and a first IP gateway (IPGW) with a home agent (HA) when a wireless communication session is established between the mobile AT and the first IPGW. In various embodiments the method additionally includes transferring context information regarding the mobile AT and a proxy mobile security key obtained by the first IPGW, from the first IPGW to a second IPGW when the mobile AT moves from a first access network to a second access network.

Packet-forwarding for proxy mobile IP

A Multiple Bit Rate (MBR) video coding method and apparatus for performing video encodings at multiple bit rates and for performing advantageous switching therebetween. Frequent switching points and high video coding efficiency are achieved with use of a plurality of video encodings at each of a plurality of bit rates, wherein the switching points between multiple encodings at a given bit rate are shifted with respect to one another so that the frequency of available switching points is significantly improved without a corresponding loss of coding quality. In addition, one or more 'high quality' encodings may be provided at each bit rate, wherein the 'high quality' encodings employ infrequent switching points, providing a very high quality encoding at the given bit rate which may be used (or switched to) whenever possible.

Method and apparatus for performing multiple bit rate video encoding and video stream switching

An audio file is linked to a record in a database. The record is accessed and the audio file related to the record is obtained. Once the audio file is obtained, it is recorded on a recording media. The audio file is then linked to the record. In one embodiment of the invention, linking the audio file to the record is accomplished by storing a pointer to the location of the audio file on the recording media in a field of the record. In another embodiment of the invention, the audio file is digitized and the digitized audio file is stored in a memory. The digitized audio file is stored in one of two ways: either in a field of the record, or separately from the record. In the latter case, a pointer to the audio file is stored in a field of the record. Linking the audio file to its related record allows quick and easy access to the audio file from the record. This is particularly useful for client databases since the linking allows quick and easy access to conversations with a client about the client's accounts and/or transactions.

Database with linked audio file

An active session mobility solution for point-to-point protocol (PPP) in accordance with the present invention provides fast and smooth handoff by reducing tunneling overhead on tunneling mechanisms, such as P-P tunneling from a serving Source (e.g., a PPP termination device) to a new serving Target (e.g., a PPP termination device). In the active session mobility solution of the present invention, PPP session can be migrated even if not all phases have been completed (e.g., LCP, PAP/CHAP completed but not IPCP and CCP). In such cases, the incomplete phases will be negotiated at the PPP of the Target PPP.

Active session mobility solution for point-to-point protocol

The present invention provides a method of wireless telecommunication in a distributed network comprised of a plurality of access points. The method includes receiving information indicating that a dormant call session is to be activated. The method also includes providing an identifier indicative of the dormant call session. The identifier includes information indicative of an access point having information indicative of a state of the call session stored thereon.
