Abstract: The invention consists of a new registration and authentication protocol for between a Mobile Node and a Home Agent. The new protocol uses a novel messaging sequence to request registration, authentication and authorization of the Mobile Node when it is located on a foreign network, and the novel protocol will avoid some of the standard registration and authentication protocol messages in order to eliminate the problems associated with re-transmission errors.

Abstract: A system and method is provided for performing an access network discovery and selection function in a communication system. An access network discovery and selection function (“ANDSF”) server is operable with a Third Generation Partnership Project (“3GPP”) radio access network and a Wireless Fidelity (“Wi-Fi”) radio access network coupled to a core network. The ANDSF server is configured to communicate with a user equipment over an enhanced S14 interface. The enhanced S14 interface comprises Wi-Fi radio access technology data including a basis service set (“BSS”) load indication, security information, quality of experience information, backhaul network bandwidth and average throughput. The ANDSF server is also configured to provide policy information to the user equipment based on conditions in the Wi-Fi radio access network and the 3GPP radio access network.

Abstract: Various embodiments are described to assist in reducing handoff delays and the blackout period(s) associated with inter AN (access network) hard handoffs. The hard handoff procedure of method disclosed herein establishes or initiates a connection (A10-type connection) between a target AN and a packet data serving node (PDSN), unlike known hard handoff approaches that wait until traffic channel assignment to establish or initiate such connection. The PDSN may optionally bicast data packets to both the source and target ANs since each is communicatively coupled to the PDSN during a given time period. In the event bicasting is unavailable or unused, a communication tunnel between the source and target ANs may be created and used to transmit data packets between them.

Abstract: Various embodiments are described for Point-to-Point Protocol-free (PPP-free) access and service authentication in a wireless network. An HRPD connection/session is established between an access terminal and the access network. Instead of setting up a PPP session and performing access (i.e., device access) authentication and service authentication using PPP, the Extensible Authentication Protocol (EAP) is utilized.

Abstract: A telecommunication device (e.g., mobile phone, smart phone, tablet, laptop computer, personal computer) and method are described herein that utilize multiple communication applications (e.g., phone call, SMS, email, social networking applications (e.g., Facebook, Twitter, LinkedIn . . . )) and a smart address book device (e.g., master contact list, user approved contact lists) to enable a user to send a communication event (e.g., voice call, SMS, email, social networking communication, multimedia session, web based real time communication session) to one or more recipients.

Abstract: A system and method for transferring application-specific functionality from a mobile handset to a wireless network associated with the mobile handset. A network component of the system communicates with a virtual copy of the mobile application on behalf of the handset while the handset is not actively using the application and performs any necessary application execution on behalf of the handset. The network component transfers execution back to the handset when the handset resumes active use of the mobile application.

Abstract: Various embodiments describe an authentication protocol for the Home Agent to authenticate and authorize the Mobile Node's Binding Update message. Two new mobility options compatible with RADIUS AAA are used to exchange a shared secret between the Home Agent and the Mobile Node so the Mobile Node can be authenticated. A Mobile Node-AAA authenticator option is added to the Binding Update message. The Home Agent generates the Mobile Node-AAA authenticator as a shared secret that it communicates as authentication data to the RADIUS AAA server on the home network. The RADIUS AAA server authenticates the communication and generates an Access-Accept message with a Mobile Node-Home Agent authenticator option. After receipt at the Home Agent, a Binding Update message with the Mobile Node-Home Agent authenticator option is transmitted from the Home Agent to the Mobile Node to use as an authenticator.

Abstract: Provided is a method of providing secure communication between an initiator and a responder in a communication network. The method includes providing an encryption key for securing communications between an initiator and a responder in a communications network that includes the initiator generating an initiator Diffie-Hellman computed value, the initiator transmitting the initiator Diffie-Hellman computed value to the responder, the responder generating the encryption key and a responder Diffie-Hellman computed value, the responder transmitting the responder Diffie-Hellman computed value to the initiator, and the initiator generating the encryption key.

Abstract: A UE and a method are described herein for optimizing a non-optimized handoff from a first access technology (e.g., E-TRAN, WiMAX, UMTS, WiFi, UMB and E-UTRAN) to a second access technology (e.g. 1×RTT, 1×EVDV, HRPD or eHRPD). In one embodiment, the “optimized” non-optimized handoff effectively decreases the mute time that is experienced by the UE during the handoff from the first access technology to the second access technology from around 628 ms to less than 500 ms which is a marked improvement.

Abstract: The present invention supports a communication protocol on a wireless communication network to transmit application data on the control channel to an access terminal. Base transceiver stations are grouped and configured into paging zones. The radio network controller transmits a page message and application data to the base transceiver stations in the paging zone where the access terminal is located. Each of the base transceiver stations transmits a page and buffers the application data. The buffered application data is only transmitted by the base transceiver station receiving a response to the page.

Abstract: Provided is a method of providing secure communication between an initiator and a responder in a communication network. The method includes presenting a registration request with one or more proposals for dynamically establishing a security association between the initiator and the responder, and receiving a registration response indicating whether any of the one or more proposals have been accepted for the security association.

Abstract: A push to talk message protocol operating on a communication network between an originating and terminating communication device operates to transmit compressed message formats to initiate the push to talk message protocol. Four compressed session protocol message formats are used in the preferred embodiment. A compressed originating session initiation invite message is transmitted from the originating mobile station. A compressed terminating session initiation invite message is received by the terminating mobile station. A compressed session initiation protocol ping message is transmitted from the originating mobile station and received by the terminating mobile station. A compressed 200 OK session initiation protocol message is transmitted from the terminating mobile station and received by the originating mobile station. Finally, the originating mobile decompresses the 200 OK session initiation protocol message. These compressed messages are used to initiate the push to talk communication session.
