摘要:
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.

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.

A solution for establishing a session of a real-time media communication service in a communication system comprising at least two separately administered subsystems. The session establishment comprises receiving a request for session initiation, querying subscriber information related to the requested session, and initiating the session according to the queried subscriber information. The invented method comprises detecting that the terminating subscriber does not belong to the same subsystem as the originating subscriber, determining a defined transit server associated with the terminating subscriber, said transit server having access to a subscriber database of the subsystem of the terminating subscriber, and querying subscriber information related to the requested session with a first control message comprising parameters of the requested session to the transit server. The solution allows a connection to be established between users of a real-time media communication service for subscribers of separate administrative subsystems so that operators of each subsystem may possess full control of their own network elements, and the internal connection establishment procedures need minimal alterations for the functionality.

The invention provides a method and system for routing a message or a set of messages or a session from a first equipment connected or registered to a first network, to a second equipment connected or registered to a second network. The first network includes a network entity which checks requirements of the message or set of messages or session, and decides on the routing depending on the check result. The checked requirements may include media requirements of the message or set of messages or requested session. The checked requirements can also include QoS requirements of the message or set of messages or requested session.

A method and apparatus for registering a user as a subscriber in a communication network. The method includes transmitting a registration message which defines an identity of the user to the communication network. The method also includes providing in the registration message a header field for defining at least one other identity of the user as a subscriber. The method also includes performing a one-by-one registration based on an identity information stored at a terminal device, whereby the identity information defines at least one other identity of the user as a subscriber. Thus, the user or subscriber can register some or all of his public identities at once with one registration procedure, allowing the user to utilize his identities by grouping public identities under user profiles or under private identities, while preventing unwanted calls.

The invention relates to providing services to a group of users, wherein the group of users is assigned to a first service, the group being identified by a common group identity, and each of the users assigned to the first service may have different states regarding the first service. The invention proposes methods, network control elements and terminal devices in order to provide a second service with respect to the users of the first service based on their state regarding the first service.

The present invention relates to a method and network device for processing a routing information in a packet data network. The routing information is extracted from a received message at a border between a first network and a second network, and at least one invalid entry is added to first-network entries of the routing information. The first-network entries relate to a routing path of the message within the first network. The at least one invalid entry and the first-network entries are encrypted by using an own token at least for each of the first-network entries. As an alternative, a tokenized second-network entry extracted from said routing information and relating to the routing path of the message within the second network is decrypted, and its content is reversed. In both cases, the routing information is replaced by the processed routing information and the message is forwarded to the second network. This allows to preserve the order of routing entries and to hide the amount of switches that have been traversed in the home network.

The present invention relates to a method and a system for controlling a processing load in a packet data network, wherein a load control information is set in a predetermined field of a message. The load control information is then checked on the routing path of the message and a processing resource of the packet data network is selected in response to the result of checking step. Thereby, load balancing information can be provided at the network to thereby provide an efficient balancing and load sharing function without heavy string comparisons and data base queries.
