  • Adaptable network service access through dynamic request routing
    Patent number: 9801043
    Abstract: In an Internet Protocol Multimedia Subsystem (IMS) network in which multiple subscriber data servers are deployed with partitioned subscription data for users, a subscriber location function (SLF) is used to proxy queries to a subscriber data server (such as an HSS) in which subscription data for a user can be found. The SLF receives a query for the subscriber data server, looks up the address of appropriate subscriber data server and proxies the query to the appropriate subscriber data server. Preferably, the SLF is co-located with a subscriber data server.
    Type: Grant

  • Resilient network database
    Patent number: 8423678
    Abstract: This invention relates to methods and apparatus for providing a resilient network database. The invention relates particularly, but not exclusively, to the IP Multimedia Subsystem (IMS). The invention is directed to an interface for a database node comprising: a port for receiving a request for information from a network node; a processor for determining if the database node can respond to said request; and a transmitter for forwarding the request to another database node if the particular database node cannot respond. The invention is also directed to a distributed database comprising a number of database nodes, wherein a request received by one node is forwarded to other nodes in the distributed database if the particular node cannot handle the request.
