  • Patent number: 9762621
    Abstract: A method of routing an IP Multimedia Subsystem, IMS, connection request sent by a user of a third party service, User A, towards a peer third party service user, User B, where the originating identity and target identity fields contain respectively external third party identities of User A and User B. The method comprises receiving said request at an IMS Access Gateway to an IMS network, and extracting said external identities and determining whether the extracted external identities are registered in respect of a wildcarded IMPU or wildcarded IMPUs that in turn is or are registered in the IMS network. In the event that these are registered, it is determined whether or not service logic is to be executed in the IMS network for both User A and User B and, if not, an IMS Edge Node routable identity associated with User B is determined. The IMS Edge Node routable identity is used to forward the IMS connection request to a terminating side IMS Edge Node.

  • Patent number: 9596270
    Abstract: Requests between first and second IMS network domains are communicated by receiving an XDM request in the first domain. The XDM request relates to an XML document that can be accessed via the XDM request from a location in the second domain. A SIP request is created that includes information identifying it as a request that relates to an XDM request. The SIP request is sent to the second domain so that the SIP request can be routed to the location in the second domain based on the identifying information in the SIP request. A connection for XDM requests between the first and second domains is established.

  • Patent number: 9591129
    Abstract: A method in a communication network of delivering messages associated with an information exchange service. A message, to be delivered between two entities is interrogated to determining if the data content has already been delivered to the terminating entity. If the data content has not already been delivered to the second entity, the message is transmitted to the second entity unchanged, while the message is modified, so that the modified message comprises a data identifier, identifying the data content, but no data content. The modified message is then transmitted to the terminating entity, and the data identifier is cached together with the associated data content when a successful transmission of the message has been verified. The suggested versioning mechanism enables transmission of messages with a reduced size.

  • Patent number: 9332062
    Abstract: A method and arrangement for handling document requests in a communication services network. When a first document server (200) receives (2:1) a request for a first service document from a requesting party (200), the requested first service document (Doc 1) is retrieved (2:2), which comprises a reference (ref) to service related information in a second service document (Doc 2). The first document server (200) then fetches (2:3) said service related information (list) in the second service document using the information reference, and aggregates (2:4) the fetched service related information with the first service document. The first document server (200) finally returns (2:5) the first service document together with the aggregated service related information (Doc 1?) to the requesting party in response to the received document request. Thereby, the requesting party is not forced to request for more documents than the first service document to obtain the needed information.

  • Patent number: 9268877
    Abstract: A method, a server and a client for enabling time limited modifications of XML nodes in XML documents, where a modified document can be restored to its original content upon expiry of an expire time, which has been specified for the modification, are provided. A request for a time limited modification of an XML node, including an expire time, is transmitted from a client to a server. At the server, a timer is either started, in case no timer is pending for the XML node, or re-set, in case a timer is already pending for the XML node. The present version of the XML node is stored, before it is modified, according to modification data provided in the request. Upon timer timeout the requested modification will no longer be valid, and therefore the XML node is restored to its stored version of the XML node.

  • Patent number: 9106671
    Abstract: Presented are methods and apparatus for optimizing access to service capabilities information for clients associated with user in a communication system. Communications requesting service capabilities information is directed through one or more capabilities application servers for inspection before forwarding the requests to their destination user's client device. If the capabilities application server has previously stored the information then the reply is generated from information stored on the capabilities application server and no request is forwarded to the user's client device, optimizing the process by reducing network communications.
