摘要:
Method and system for processing a request associated with a user from a requesting node to an answering node in a telecommunications network. A repository is associated with the answering node, the repository including a data structure including a plurality of user profiles associated with a plurality of users. In the answering node a user profile of the plurality of user profiles is associated with the user. The method comprising the steps of assigning a unique user index to each user profile in the data structure, wherein the user index is representative of the location of the user profile within the data structure, communicating at least one user index to the requesting node, incorporating the user index in the request by the requesting node, transmitting the request from the requesting node to the answering node, and retrieving the user profile associated with the user associated with the request by the answering node on the basis of the user index.
摘要:
Signalling messages in an Internet Protocol, IP, communications network comprising a chain of at least two entities (21; 23; 29) applying object oriented processing (22; 28; 42) of signalling messages are exchanged between the at least two entities (21; 23; 29) of the IP communications network comprising object oriented based data items. Parsing and inverse parsing of text based signalling messages are effectively avoided, thereby reducing system resources and increasing processing speed of the system as a whole.

Method and user equipment and network node for sending a SIP request message having alerting information associated therewith from an originating user equipment having an originating SIP-UA associated therewith to a receiving SIP-UA associated with a receiving user equipment in a SIP based communications network, including setting a condition which must be met in order for the receiving SIP-UA to be allowed to receive the alerting information, checking whether the condition has been met, and f the condition has been met, passing the alerting information on to the receiving SIP-UA.
摘要:
Method and system for transferring a message, comprising routing information relating to the intended recipient of the message and content information, from a first node via a second node to a third node in a communications network. According to the invention, a repository is associated with the second node. The method comprises the steps of: transmitting the message from the first node to the second node; storing data representative of the content information in the repository of the second node; replacing, by the second node, in the message, the content information by a token; transmitting the message, comprising the routing information and the token, from the second node to the third node; retrieving, by the third node, the content information from the second node; and replacing by the third node, in the message, the token by the content information.
摘要:
A method of operating a first communication device (3) for receiving a media data stream (64) from at least one second communication device (5) in a telecommunications system. The first communication device (3) exchanging with the at least one second communication device (5) Session Initiation Protocol, SIP, messages (60, 62, 63, 64, 67, 70) during a SIP dialogue. The SIP messages (67, 70) including a late media indicator (68, 71) that includes an indication that the media stream (64) continues (72) after the SIP dialogue has terminated, or an indication (75) of support of receiving media stream after the SIP dialogue has terminated. The SIP dialogue controls the media data stream (64, 72). The first communication device (3) receives the media data stream (64, 72) from the second communication device (5). The first communication device (3) continues to receive the media data stream (72) after the SIP dialogue has ended.
摘要:
Method and network unit for setting up a connection in a second network (16) from a first user terminal (21) to a second user terminal (22), when a connection in a first network (15) is present between the first user terminal (21) and at least the second user terminal (22). The connection in the second network (16) is initiated using a context dependent second network address, the context dependent second network address identifying a combinational service in the second network (16). The combinational service comprises retrieving the second network address of the second terminal (22) using a common part (17) of the first and second network (15, 16), and completing the set up of the second connection using the second network address of the second terminal (22).

A method (10) of and a server (60) and telecommunication system (30) for establishing communication (11) from a first party (31) having a first party identity to a second party (32) having a second party identity, wherein said first party identity is withheld for said second party (32). A token or correlation identifier (67) unique for the communication is generated (15), and the token or correlation identifier (67) is associated (16) with the first party identity for establishing a further communication in the telecommunication system (30) between the first party (31) and the second party Calling party (32) based on this token or correlation identifier (67).

摘要:
Method and server entity for forwarding a message containing a host name or domain name in an interne based communications network from a User Agent (UA) to the communications network or vice versa. The method comprises the steps of querying, by a proxy entity, a Domain Name Server (DNS) for obtaining from the Domain Name Server an Internet Protocol (IP) address associated with the host name or domain name, and including the Internet Protocol address in the message prior to forwarding the message to the communications network or User Agent, respectively, by the proxy entity.
摘要:
A system and method for simultaneously supporting IMS signaling and Circuit Switched signaling during a call between a calling user terminal in an IP Multi media System (IMS) and a called user terminal in a Circuit Switched CS network. A first IP address is determined by the calling user terminal, the calling user terminal initiates the call using IMS signaling towards the called user terminal, the IMS signaling comprising the first IP address. The called user terminal then initiates a CS connection towards an IP Access Converter using CS signaling and comprising the first IP address. The IP Access Converter allocates a second IP address (IP2) to be used for data transfer with the calling user terminal. The IP Access Converter establishes the CS connection by providing said second IP address to the called user terminal using CS signaling and the called user terminal establishes the call, providing said second IP address to said calling user terminal using IMS signaling. Data transfer occurs between the calling user terminal and the IP Access Converter using the first IP address and second IP address, and between the IP Access Converter and the called user terminal through the CS connection.
