20110124339 | EARLY IMS SECURITY - A method for providing Early IMS Security in a network. In registering a terminal on a telecommunications network, a plurality of private user identities (IMPIs) are derived from the IMSI of the terminal. Some or all of these IMPIs are registered with the network. Each IMPI has its own IRS containing its own IMPUs, enabling different identities of the user to be registered with the network. | 05-26-2011 |
20120059878 | METHOD AND ARRANGEMENT FOR ENABLING DIFFERENTIATED COMMUNICATION SERVICES - Methods and arrangements for enabling execution of a communication service adapted to a client by an application server. One or more iFC:s are configured in a central subscriber data node for the client by including information related to user specific service data of the client in the iFC:s. When receiving a request related to the client, a session control node fetches the iFC:s of the client from the subscriber data node if the client is not registered. The service data related information is then extracted from an iFC of the client that matches the received request, which is forwarded to the application server with extracted service data related information attached. The application server creates user specific service data for the client based on service data related information in the request, and serve the client accordingly. No regular provisioning operation and interface towards a provisioning system are required for the application server. | 03-08-2012 |
20120307813 | Methods for Routing of Calls in Internet Protocol Multimedia Subsystem Centralized Services Networks and Related Gateway Mobile Switching Centres (GMSC) and Home Location Registers (HLR) - Methods for routing a call involving an Internet Protocol (IP) Multimedia Subsystem Centralized Services (ICS) subscriber accessing an IP Multimedia Subsystem (IMS) network using a circuit switched (CS) access network are provided. The method includes receiving an incoming call request for a user at a gateway Mobile Switching Centre (GMSC); accessing a Location Register storing information relating to the user to determine if the user is an ICS subscriber; and generating and forwarding a SIP INVITE message to the IMS to establish the call if it is determined that the user is an ICS subscriber. Related Gateway Mobile Switching Centres (GMSCs) and Home Location Registers (HLR) are also provided herein. | 12-06-2012 |
20130114592 | IMS CALL ROUTING USING TEL-URIs - The present invention proposes a specific handling of tel URIs in an IMS terminating network so as to enable routing of calls using telephone numbers (and not SIP URIs with embedded telephone numbers) as identifiers of the target users of those calls. Specifically, the present invention introduces a conversion module which is located within the IMS terminating network and is capable of converting SIP URIs with embedded telephone numbers into equivalent tel URIs which are then used by a terminating I-CSCF and S-CSCF to query the SLF and/or HSS so that, they can route the calls to the target users. | 05-09-2013 |
20140073333 | ROUTING TERMINATING CALL TO USER EQUIPMENT VIA CONTROL NODES - A method for routing a terminating call to a user equipment via a first control node for controlling the call, wherein the user equipment is attached to a second control node which is adapted to provide routing information. The method comprises determining, by the second control node, if the user equipment is attached to the second control node over a third control node, wherein the attachment over the third control node indicates that call control shall be performed by a specific service domain. Based on the determining, the provided routing information is selected by the second control node, wherein the routing information indicates to the first control node if the further call establishment to the user equipment is controlled either by the second control node or by the third control node. The call is then routed, by the first control node, according to the selected routing information. | 03-13-2014 |
