摘要:
An apparatus, and an associated method, for directing communications of a communication session to a selected communication device, or devices, of a group of commonly-registered devices. A device-direction policy is created and stored at a network entity. The policy identifies preferred devices to which communications of a communication session are to be provided. A SIP Invite, or other communication-session initiation message, is provided to the network entity. The network entity detects the message, accesses the policy, and forwards on the message in accordance with the policy.

Communication devices capable of at least two communication modes (e.g. WLAN, WMAN and WWAN and/or wired modes) can be configured to optimize communications using a policy-based mechanism to configure connections and routes. A rules engine evaluates its policies on a state change (e.g. network availability, time of day, etc.) to configure a routing table and, together with communication APIs, provides an appropriate connection to an application for its respective communications. Policies may be responsive to various factors such as Radio Access Technology (high/low bandwidth), cost, presence, time of day, location, application type and quality of service (QoS) requirements among others to optimize communications.
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:
Methods and apparatus for originating a Session Initiation Protocol (SIP) call from a user equipment (UE) device in a network environment including a circuit-switched (CS) network and an IP multimedia subsystem (IMS) network to a called party are disclosed. In one illustrative example, when the SIP call is originated by the UE device in the CS network domain, a SIP Invite message which includes a SIP Uniform Resource Indicator (URI) or Tel URI of the called party is sent from the UE device to the IMS network (e.g. to an application server (AS) node). At the AS node, a pool of E.164 numbers are maintained as IP multimedia routing numbers (IMRNs) which are utilized for mapping to or otherwise associating with called party URIs. Thus, the AS node dynamically allocates a select E.164 number with respect to the called party's URI received from the UE device, and returns it to the UE device in a SIP Response message, e.g., a SIP 380 (Alternative Service) message. Subsequently, the dynamically-allocated E.164 number is sent from the UE device in a call setup message for identification of the URI at the AS node, via the mapping, so that the SIP call may be properly routed towards the called party.
摘要:
A method for providing a user agent (UA) with service identification data. The method includes an application server (AS) transmitting Session Initiation Protocol (SIP) data. The SIP data comprises an identifier of the AS and a service identifier for at least one service supported by the AS. The method further includes the UA receiving the SIP data.
摘要:
In one embodiment, a scheme is disclosed for managing delivery of a Mobile-Terminated (MT) call via an IMS network, wherein the MT call is originated by a calling party towards a User Equipment (UE) device that is CS-attached. An IMS-capable network node is operable to associate the received call information with an IP Multimedia Routing Number (IMRN) and provide the call information and the IMRN via alternative signaling (e.g., USSD or SMS messaging) to the UE device. A Mobile-Originated (MO) call process is initiated by the UE device using the received IMRN as the destination number, which terminates at the network node. Upon verifying that the returned IMRN is valid, the network node bridges the access and remote legs to establish the end-to-end path for the MT call between the UE device and the calling party.
摘要:
A system comprising an inter-RAT/inter-network redundancy controller (IRC) is provided. The IRC is configured to communicate with a source gateway in communication with a source radio access network (RAN) using a first radio access technology (RAT). The IRC is further configured to communicate with a target gateway in communication with a target RAN using a second RAT. The IRC is further configured to promote a handover of a user equipment from the source RAN connected to the source gateway to the target RAN connected to the target gateway when the source gateway fails.
摘要:
A system and method for concealing an identity by receiving a Session Initiation Protocol (SIP) message, the SIP message containing a field, the field containing a Globally Routable User Agent Uniform Resource Identifier (GRUU) identifying a node, the GRUU containing a public user identity (PUID), a ‘gr’ parameter, and a ‘gr’ parameter value; evaluating a subscription option; and in response to evaluating the subscription option, concealing an identity of the node by removing the ‘gr’ parameter and the ‘gr’ parameter value from the field.
摘要:
A network node is provided. The network node includes a component configured to use a value in a Session Initiation Protocol message. The value indicates a supported transport addressing scheme and is used to determine whether to route a related communication session through a transport addressing scheme translation component.

In one embodiment, a scheme is disclosed for facilitating responding to a request in a network environment including IMS. A component associated with a recipient is configured to receive an incoming message from a sender, wherein the incoming message is substantially free of an indication of acceptance by the sender of a body of a particular content type. A component associated with the recipient is configured to provide an outgoing message including at least one body of the particular content type.
