摘要： The present invention provides a method for supporting handoffs of a first mobile unit in a wireless communication system that supports multiple vocoder technologies. The method includes allocating, prior to completion of a handoff of the first mobile unit, a transcoder function to the first mobile unit. The method also includes detecting a change in a format of at least one packet received from the first mobile unit. The change indicates that the vocoder technology used by the first mobile unit to form packets has changed. The method also includes transcoding packets in response to detecting the change in the format.

摘要： The apparatus and method are fast network SIP/SDP (Session Initiation Protocol/Session Description Protocol) procedures for conference operations upon request from end user with optimization of network resources. The apparatus has an SIP/SDP based network controller that, upon a received request, joins first and second calls into a conference call with at least a third call. The SIP/SDP based network controller is structured to negotiate, allocate and re-configure network resources.

摘要： The present invention provides methods of inter-technology handoff of a multi-mode mobile unit in a packet-switched communication system. One embodiment of the method includes establishing a call from a first application layer client in the first mobile unit using a first wireless communication link that operates according to a first wireless access technology. The method also includes sending, in response to detecting changing conditions of the first wireless communication link, a request to form a conference call including the first application layer client and inviting a second application layer client in the first mobile unit to join the conference call. The second application layer client uses a second wireless communication link that operates according to a second wireless access technology. The method further includes handing off the call from the first application layer client to the second application layer client.

摘要： Communication networks and methods are disclosed for performing charging in LTE/EPC communication networks. In an LTE/EPC communication network, a PCRF stores charging rules for online and offline charging. To perform charging for a session, LTE network elements that are serving the session request charging rules from the PCRF. The PCRF identifies the charging rules, and assigns a unique LTE charging identifier for the session across all network elements in the LTE/EPC communication network. The LTE network elements receive the charging rules from the PCRF along with the LTE charging identifier for the session. The LTE network elements generate charging messages for the session, and insert the LTE charging identifier in the charging messages. The LTE network elements then transmit the charging messages to a charging system, such as an OCS or an OFCS. The OCS/OFCS may then correlate the charging messages for the session based on the LTE charging identifier.

摘要： Communication networks and methods are disclosed for performing online charging credit control in a visited network when a user is roaming. The visited network which is providing service to a roaming user includes a proxy online charging system (OCS) that communicates with a home OCS in a home network of the user. The proxy OCS transmits an online charging request message to a home OCS in a home network for the roaming user requesting charging information for the roaming user. The proxy OCS receives an online charging response message from the home OCS that includes the charging information for the roaming user. The proxy OCS then processes the charging information to perform credit control for one or more network elements in the visited network that is serving the session.

摘要： The present interoperability system serves to pass presence and supervision information relating to a user's wireless station set between a cellular communication network and an enterprise communication network. The interoperability system functions to extend the services, such as call pick up, provided in the enterprise communication network to the cellular communication network based on the presence and supervision data provided by the interoperability system. The provision of ubiquitous call pick up service is accomplished by transmitting alert signals not only to the user's telephone line in the enterprise communication network to alert members of the call pick up group proximate to the user's office, but also to the user's wireless station set operating in the service area of the cellular communication network as well as members of the call pick up group also operating in the service area of the cellular communication network.
