20080215736 | Method and Apparatus for Allocating a Server in an Ims Network - A method, apparatus, and application server for dynamically allocating an application server within an IP Multimedia Subsystem (IMS). A Serving Call/Session Control Function (S-CSCF) receives a user request and queries a central database to determine whether the user is allocated to an application server. If so, the S-CSCF forwards the request to the allocated application server. If the user is not already allocated to a server, the S-CSCF allocates the user to an application server and forwards the request to the newly allocated application server. The S-CSCF or the newly allocated application server sends a request to the central database to record the allocation. | 09-04-2008 |
20080247384 | 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. | 10-09-2008 |
20100232422 | GROUPING OF USER IDENTITIES IN AN IP MULTIMEDIA SUBSYSTEM - The present invention is aimed to provide a more flexible data structure where any IMPU, even those of the SIP URI type, may be shared by more than one IRS in order to simplify the registration of an IMPU for users of a Fixed-Mobile Convergent network. To this end, there is provided a flexible data structure wherein a number n of IMPUs of a user may be distributed in a number m of Implicit Registration Sets, wherein a given IMPU may be shared by more than one IRS, each IRS is associated with an access condition, and the explicit registration of said given IMPU under a given access condition triggers the implicit registration of those IMPUs in the IRS associated with said access condition, whilst the registration status of IMPUs in any other IRS remain unchanged. | 09-16-2010 |
20100281251 | Mobile Virtual Private Networks - An apparatus for establishing a virtual private network with an internet protocol multimedia subsystem (IMS) device that includes a key derivation module, a tunneling protocol module, a tunnel management module, and a security policies module. The apparatus includes a non-volatile memory configured to store a first routing table that maps host addresses and IMS addresses of security devices allowing access to those hosts, such that when an application running in the IMS device requests communication to a host address, the apparatus initiates a session with the IMS address to which the host address is mapped. The session is initiated by a message that includes a body that contains, for each tunneling protocol supported by the tunneling protocol module, data about the local tunnel endpoint (e.g., an address and a port), an identifier corresponding to the tunneling protocol, and identifiers corresponding to the cryptographic suite(s) supported by the cryptographic module that may be applied together with the tunneling protocol, as determined by a query from the apparatus to the security policies module. | 11-04-2010 |
20110110271 | IMS-BASED DISCOVERY AND CONTROL OF REMOTE DEVICES - The present invention faces the issues of remotely controlling multiple LAN-attachable devices ( | 05-12-2011 |
20110310884 | TELEPHONY ENDPOINT ROUTING IN AN IP MULTIMEDIA SUBSYSTEM - The present invention provides a mechanism whereby a session established at a particular MGCF between a subscriber of a legacy network and a first user of a referral service can be replaced by another session to be established between the subscriber of the legacy network and a second user of the referral service without disturbing the sessions already established. Therefore, the present invention provides a new method and devices for generating an IMS Telephony Endpoint, which includes a first information field with a telephony Universal Resource Identifier identifying an originating or destination subscriber, as the case may be, and a second information field with information usable to identify the generating MGCF as the particular MGCF holding a session for such served subscriber. Such ITE is submitted towards the IMS and is included in a further referral service request involving such session so that the particular MGCF may be identified. | 12-22-2011 |
20130083806 | TRAFFIC CLASSIFICATION - According to a first aspect of the present invention there is provided an apparatus configured to classifying user traffic flows carried by a network, each user traffic flow being associated with one of a plurality of users. The apparatus comprises a classification unit | 04-04-2013 |

20140201238 | Data Distribution/Retrieval Using Multi-Dimensional Index - A distributed data storage system uses a data distribution and location algorithm based on distance functions and hyper-spheres in a multi-dimensional space. The distributed data storage system uses the algorithm to maintain, over time, a balanced distribution across a number of computers interconnected by a network of a varying set of data items. Each data item includes one or more key fields. The system also includes an efficient partial-match and exact-match search across a whole set of data items using as search criteria the values of any or all of the sought data item's key field(s). | 07-17-2014 |
