The method also includes selecting a numbering plan out of plurality of numbering plans based on at least one of the country and network where the second party is located. The method also includes converting the telephone number from the first format to a second format using the selected numbering plan.

Abstract: A system and method for managing next hop addressing where multiple address schemes are provided in messages transmitted via a network. A predefined addressing policy may be applied to an incoming message if the predefined addressing policy includes a policy corresponding to an incoming address scheme of the incoming message. The incoming address scheme is converted to one or more outgoing address schemes provided by a location service in response to a location query. A plurality of outgoing messages is dispatched, each using one of the outgoing address schemes provided by the location service. A default next hop addressing operation is effected when the predetermined addressing policy does not correspond to the incoming address and when none of the multiple outgoing address schemes provides a useful result.

Abstract: A method manages communication over a shared resource in a communication system. A plurality of access requests are received, wherein at least one of the plurality of access requests is provided with a predefined indication whether the access request relates to a topic currently communicated over the shared resource or not. The plurality of access requests are verified for the predefined indication and are handled based on a predefined policy, wherein the predefined policy utilizes the predefined indication as one criterion. A managing entity and a communication system are configured to execute the method. A communication device is configured to create an access request provided with the predefined indication.

Abstract: Rejecting a session request initiated via a session establishment protocol involves receiving, at a first network terminal, a session initiation request sent from a second network terminal via the session establishment protocol. A rejection message of the session establishment protocol is formed based on a presence state of the first network terminal. The rejection message is sent via the session establishment protocol targeted for the second network terminal.

Abstract: A method of establishing a conference call in a communication network between a plurality of user terminals each having an identifier.

Abstract: A method for use by an I-CSCF (12b) in resolving an address of a message according to SIP but using a protocol-agnostic scheme, and corresponding equipment. The method includes: a step (32) of querying a data store (12c) of scheme mappings, in response to receiving such a request, the querying for determining possible mappings to trial schemes at least one of which resolves the address, i.e. which can be used by the I-CSCF (12b) to find the S-CSCF (12e) for the target user (11b) if the target user is an IMS client, or for forwarding to a gateway or next hop in the path to the target user (11b) if the target user (11b) is not an IMS client; and a step (33) of testing in turn (until success or until all possible trial schemes are tested) each possible trial scheme, the testing based on comparing an address using the trial scheme with an address in a data store (12d) of addresses.

Abstract: A system, apparatus and method for rejecting a session request is disclosed. The session establishment request is initiated via a session establishment protocol operable via a network. In one configuration, a first network terminal receives a session establishment request sent from a second network terminal via the session establishment protocol. A message template is selected from one or more message templates of the first network terminal. Each message template includes a reason descriptor describing reasons the session cannot be established. A rejection message of the session establishment protocol is formed based on the selected message template. The rejection message is sent via the session establishment protocol targeted for the second network terminal. The reason descriptor is communicated to a user of the second network terminal.

Abstract: A method (and corresponding equipment) by which a UE device (10) begins compressing messages it transmits to an SIP outbound proxy server (12) as SIP signals, including: a step (22a) in which the UE device sends a request message (22a 32a 42a) to the SIP outbound proxy server (12); and a step (23 33 43) in which the UE device analyzes a response message (22b 32b 42b) received from the SIP outbound proxy server (12) in response to the request message (22a 32a 42a) to determine a compression parameter. The request message (22a) may be an options request message and the response message (22b) would then be e.g. a 200 OK message. Alternatively, the request message (32a) may be a register message, and the response message (32b) would then be e.g. a 401 (unauthorized) message. In another embodiment, the response message (42b) is any compressed message.
