摘要:
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.
摘要:
A system and method for reestablishing a voice communications session moderated by a group call server between two or more telephony devices. The method is performed by a processor monitoring the communications session. The method comprises: storing one or more data records representing group call information; detecting disconnection of at least one participating telephony device from the group communications session, and determining that the disconnection was not intentionally initiated; accessing the stored call group information data and causing signals to enable reestablishment of participation by the disconnected device to be sent to the disconnected device; and upon receipt by the group call server from the disconnected device of signals representing a request to reconnect the disconnected device, outputting command signals for reestablishing a communications session between the disconnected device and at least one other device participating in the group communications session.
摘要:
A method for a watcher to receive presence information. The method includes the watcher requesting presence information from a presence access layer and then disconnecting from the presence access layer. The method further includes the presence access layer receiving the requested information through a persistent session with a presence server, storing the requested information, and delivering the requested information to the watcher after the watcher reconnects to the presence access layer.
摘要:
A method comprising the steps of using a processor running a program to perform the step of receiving, at an advertising entity, a report message containing an identifier of an application which presented advertisements, and a data structure with metrics for the advertisements which were presented by the application.
摘要:
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.
摘要:
A context aware mechanism including a system configured to receive presence data relating to at least one of a presentity and a watcher, and to resolve a conflict that arises during processing of the presence data according to a criteria. A method is also provided.

摘要:
A method for providing presence-related information is provided. The method includes creating a template of presence parameters for an application, storing the template, a presence access layer retrieving the template, the presence access layer using the template to create a profile of at least one presence parameter for the application, and the presence access layer using the profile to specify a presence-related action for the application.
摘要:
A method for a presentity to provide private presence information for a watcher. The method includes the presentity providing the private presence information in an encrypted form. The method also includes a presence access layer obtaining the private presence information. The method also includes the presence access layer performing one of decrypting the private presence information and sending the decrypted private presence information to the watcher, and leaving the private presence information in the encrypted form and sending the encrypted private presence information to the watcher, wherein the watcher decrypts the private presence information.
摘要:
A method for providing information to a watcher is provided. The method includes a presence access layer receiving presence-related information from a plurality of disparate presence platforms, the presence access layer using the presence-related information to derive a single element of presence information, and the presence access layer delivering the single element of presence information to the watcher.
