Abstract: A method for controlling services in an Internet Protocol Multimedia Subsystem, IMS, the IMS comprising a Home Subscriber Server, HSS, and a Serving Call Session Control Function server, S-CSCF. The method comprises: configuring (4110) in the HSS a service profile, SP, in relationship with the subscription to the IMS of a user, the SP comprising a set of SP data usable by the S-CSCF for processing of services of said user, transmitting (4210) the set of SP data from the HSS to a S-CSCF, and controlling (4310) by the S-CSCF the processing of services of said user according to the set of SP data received from the HSS; wherein configuring (4110) the SP comprises configuring (4115) new SP data used to identify in the S-CSCF a controlling rule, said controlling rule comprising values for one or more timers for controlling by the S-CSCF the value of a time associated to the processing of services of said user.

Abstract: Systems and methods for updating subscriber data are disclosed. In some embodiments, a method of operation of a serving node in a communication network for updating subscriber data includes receiving a modification of subscriber data for one or more subscribers and determining if updates to the subscriber data for the one or more subscribers are needed now. In response to determining that updates are needed now, the method includes communicating the modification for subscribers to one or more additional nodes and/or initiating other types of signaling towards other network nodes as a result. In response to determining that updates are not needed now, the method includes postponing the communication of the modification of the subscriber data for the one or more subscribers. In this way, signaling floods towards external network elements may be avoided when a modification is performed to subscription data that affects multiple subscribers (potentially even millions).

Abstract: A method of operating a database node of a distributed database is provided. The distributed database includes a plurality of database nodes each storing a set of data. A latency that occurs when the database node contacts a further database node in order to respond to one or more data requests that relate to a subset of data that is one of stored and intended to stored at the further database node is measured. An average latency value for communicating with each of the database nodes in the distributed database is calculated. Notifications reporting the average latency values to data distribution optimization functions in the distributed database are sent. A latency measure is reported to a further node of the distributed database.

Abstract: A method for providing of data is provided, the method comprising at a first database: providing of group data; providing of data of a first entity, in particular of a first device, the data of the first entity comprising the group data; receiving from a second database a request for the data of the first entity; determining that the data of the first entity comprises the group data and that said group data has not been sent to the second database before; and if said determining step is in the affirmative, sending the data of the first entity comprising the group data to the second database.

Abstract: The present invention faces the issue of UE enabled to communicate with an IP Multimedia Subsystem following protocol versions older than Release 9, and provides for an alternative P-CSCF restoration procedure.

Abstract: According to a first aspect of the present invention there is provided a method of operating a Lightweight Directory Access Protocol, LDAP, directory client. The method comprises, when it is required that an LDAP operation be performed for multiple directory entries, generating a message requesting the LDAP operation, the message specifying how the distinguished name of each of the multiple entries can be determined, and sending the request message to a LDAP directory server.

Abstract: According to a first aspect of the present invention there is provided a method of operating a distributed database comprising a plurality of database nodes. The method comprises, at a first database node of the plurality of database nodes, receiving a request to manipulate data from a client (B1), determining if the data is stored or is intended to be stored at the first database node and, if the data is not stored or is not intended to be stored at the first database node, forwarding the request towards a second database node of the plurality of database nodes (B2) and, prior to receiving a final response from the second database node, sending an early response to the client indicating that the data manipulation has been successful (B3).

Abstract: A LDAP collision detection mechanism and a method are described herein that allow a LDAP client to detect and avoid an update operation collision on an entry within a LDAP directory. The method includes the steps of: (a) reading data from the entry in the directory; (b) processing the retrieved data; (c) sending a request to modify the data in the entry in the directory, wherein the client is assured that the requested modification will not be performed by the directory if another client had previously performed a modification on the data within the entry that was originally read by the client. There are several different embodiments of the LDAP collision detection mechanism and the method described herein.

Abstract: Method, apparatus and computer programs for handling access to data distributed along a plurality of databases. A first message comprising a first identifier is received in a server interfacing messages before said plurality of databases, a second identifier usable for sending a message to the database storing data in relationship with the received first identifier is obtained, and a subsequent second message comprising the first identifier is sent to said database. For obtaining the second identifier, the server sends the second message comprising the first identifier to said plurality of databases, and receives a reply from a database among said plurality that stores data in relationship with the first identifier comprising an identifier of said database usable as said second identifier. The invention allows a simplified configuration when a data storage system is split into a plurality of separate databases.
