| 20090193512 | SYSTEM AND METHOD FOR ADDRESSING A UNIQUE DEVICE FROM A COMMON ADDRESS BOOK - A method and system for addressing a unique device from an address book, the method having the steps of: receiving a message having a root token and a secondary token; checking whether the root token exists within the address book, if no, creating a record in the address book with the root and secondary token; and if yes, checking whether the secondary token exists within the address book, if yes, providing a representation of the unique device; and if no, storing the secondary token against the root token in the address book. | 07-30-2009 |
| 20100103927 | METHOD AND APPARATUS FOR INTERWORKING SIP COMMUNICATION WAITING WITH CIRCUIT SWITCHING AND PACKET SWITCHING NODES - A method and apparatus for interworking a session by a Mobile Switching Center (MSC) server enhanced for IP Multimedia Subsystem (IMS) Centralized Services (ICS), the method comprising receiving at the MSC an invite message and the MSC sending a setup message comprising an information element indicating a call waiting tone on when the invite message comprises a call waiting indication. | 04-29-2010 |
| 20100109901 | Methods and Systems to Hold Functions on a Device After an Identifier is Determined - A user agent (UA) is provided. The UA includes a listener component configured to recognize at least one triggering event and, upon recognizing one of the triggering events, to enable a temporary suspension of at least one advertising function on the UA. | 05-06-2010 |
| 20100198854 | SYSTEM AND METHOD FOR SEARCHING MULTIPLE CONTACT INFORMATION SOURCES IN A NETWORK-BASED ADDRESS BOOK SYSTEM - Methods are provided for searching at least one directory that is external to an address book architecture including a client and a server. In one embodiment a client may communicate a contact search request that specifies an external directory which does not support a standard search format, the request causing the server to translate the request to an external search request in another format supported by the external directory. In another embodiment a server may translate a contact search request received from a client when the request specifies an external directory which does not support a standard search format. In yet another embodiment an interworking function, which is operable to import contact information from a legacy address book storage to a converged address book storage, of an address book server is adapted to query an external directory which does not support a standard search format. | 08-05-2010 |
| 20100329243 | System And Method For Voice Service In An Evolved Packet System - A system and method for accessing voice services using a user equipment (UE) in a communication system is provided. The UE is configured to receive a first message which may include an audio session indication. The method includes the step of sending a second message in response to the first message, with the second message being based on one or more voice service indicators comprising at least one value. The second message may be a response indicating not to select an alternative domain. The second message may also be a not acceptable response. | 12-30-2010 |
| 20100329244 | System And Method For Voice Service In An Evolved Packet System - A system and method for enabling voice services using a network component in a communication system including a user equipment (UE) is provided. The UE is configured to receive a first message which may be a SIP request. The network component is configured to create a second message, or SIP request, based upon the first message. The network component further configured to subsequently receive a SIP response and select a subsequent action upon receiving the SIP response. | 12-30-2010 |
| 20110103372 | SYSTEM AND METHOD FOR SESSION INITIATION PROTOCOL HEADER MODIFICATION - A method for modifying the contents of session initiation protocol (SIP) messages is presented. The method includes receiving a SIP message. The SIP message may include a set of message header fields. The method includes receiving an application policy. The application policy may specify how to modify the SIP message based on a characteristic of the SIP message. Alternatively, the application policy may be retrieved from a database such as one provided by a home subscriber server (HSS) or an application server. The method includes using the application policy to modify the SIP message resulting in a modified message, and sending the modified message. | 05-05-2011 |
| 20110103373 | SYSTEM AND METHOD FOR SESSION INITIATION PROTOCOL HEADER MODIFICATION - A user agent (UA) for communicating with a communications network implementing an internet protocol (IP) multimedia subsystem (IMS) is presented. The UA is configured to send and receive session initiation protocol (SIP) messages. The UA includes a processor configured to send a message to the network. The message identifies an application policy. The application policy defines at least one of a SIP message header field to include, a SIP message header field to remove, a SIP message header field to allow, and a SIP message header field to modify. The processor is configured to receive a SIP message from the network. The SIP message includes a set of SIP message header fields. The set of SIP message header fields are modified in accordance with the application policy. | 05-05-2011 |
