摘要:
A method to transfer control is presented. The method includes sending a message requesting transfer of control of a collaborative session, and receiving notification, in response to the sent message, indicative of a transfer result of said requested transfer of control. The method may include, when the transfer result in the received notification indicates success, relinquishing control of the collaborative session. The method may include maintaining control of the collaborative session independent of the transfer result in the received notification. The message requesting transfer of control of a collaborative session may also comprises a request for media transfer.

A method for performing initial registration is provided. The method includes receiving a server timeout message, the server timeout message including at least a field set to a value equal to a value received during a first registration. The method further includes initiating restoration procedures by performing an initial registration.

A method for a user agent to access a session policy in a network is provided. The method comprises the user agent sending a registration message to a first network node. The method further comprises the user agent receiving policy-related information from the first network node in a response to the registration message. The policy-related information is one of the session policy, a Uniform Resource Locator that points to the session policy, and a Policy-Contact header containing a policyContactURI for a policy document.
摘要:
A method of call routing is provided. The method comprises receiving a session initiation protocol (SIP) INVITE message that contains a uniform resource identifier (URI) of a called party and that identifies that a bearer for a call to the called party is to be set-up at least in part over the circuit switching domain. The method also comprises determining a digit string associated with the URI. The method also comprises sending a SIP informational response message having a contact header that contains information based on the digit string.
摘要:
Apparatuses and methods for facilitating anonymous messaging via a wireless network, directed to protection of information relating to a sender node. According to the disclosed apparatuses and methods, a node sending a message to one or more recipient nodes is provided with the option to conceal its identity, or at least a portion of its addressing information, from at least one recipient of the message. In order to provide compliance with applicable protocols, the sender may be assigned a temporary identifier for the purpose of transmitting the message to the recipient.
摘要:
Apparatus, and an associated method, for providing an indication of available access types by a wireless device when initiating a session. The wireless device collects information associated with available access types, available through which to communicate, at the location at which the wireless device is positioned. A report is generated that lists the collected information. The report is routed to a network node that analyzes the received information and accesses a database at which information identifying an access type, or domain type, that the wireless device should use pursuant to an emergency, or other, call. A response message is generated and returned to the wireless device. The wireless device utilizes information contained in the response message for further communications.
摘要:
In one embodiment, a domain selection method is disclosed for operation in a network environment including a circuit-switched (CS) network and an Internet Protocol (IP) multimedia subsystem (IMS) network. Policy criteria information related to a subscriber is maintained in association with a network node. A proper network domain is selected with respect to an incoming call directed to the subscriber based on at least a portion of the policy criteria.
摘要:
In one embodiment, a domain selection method is disclosed for operation in a network environment including a circuit-switched (CS) network and an Internet Protocol (IP) multimedia subsystem (IMS) network. At a network node disposed in the IMS network, status information related to a served user equipment (UE) device is maintained. Status information is preferably updated based on update information provided by the UE device. An incoming call being directed to the UE device is routed to a proper domain based on the status information, among other criteria.
摘要:
A system and method for accelerating network selection by a wireless user equipment (UE) device without having to perform a full band scan (FBS). In one exemplary embodiment, the wireless UE device is operable to scan in a network environment for discovering at least one network. Depending upon geographic region information decoded from the discovered network's identity information, a logic structure in the wireless UE device is operable to determine a subset of appropriate frequency data for selective scanning by said wireless UE device. Using the subset of appropriate frequency data, a selective scanning is performed for locating a network by the wireless UE device.
摘要:
A network selection scheme operable in a network environment having one or more radio access networks (RANs), one or more core networks (CNs), and one or more service networks (SNs). Upon obtaining identity information of a particular network combination, a wireless user equipment (UE) device is operable to register with a roaming broker (RB), whereby additional information may be provided to the device for facilitating appropriate network selection.
