| 20080212569 | Method and Apparatus for Allocating Application Servers in an Ims - A method, application server, and Serving Call/Session Control Function (S-CSCF) for allocating a SIP Application Server to a subscriber in an IP Multimedia Subsystem. A Home Subscriber Server (HSS) identifies for the subscriber, a set of provisioned initial filter criteria, which contains at least one generic SIP Application Server identity. The HSS sends the filter criteria to an S-CSCF allocated to the subscriber. The S-CSCF resolves the generic SIP Application Server identity into a plurality of application server addresses, with one of the addresses being allocated to the subscriber for use in provisioning a service to the subscriber. The S-CSCF caches the address allocated to the subscriber for subsequent use. | 09-04-2008 |
| 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 |
| 20080232352 | Method and Apparatus for Distributing Application Server Addresses in an Ims - A method of distributing application server addresses in an IP Multimedia Subsystem. Upon allocation of an application server to a subscriber, the allocated or another application server sends at least one application server address to a Home Subscriber Server (HSS). The HSS stores the address(es) in association with the subscriber identity and sends the address(es) to a Serving Call/Session State Control Function (S-CSCF) allocated to the subscriber. The S-CSCF caches the address(es) in association with the subscriber identity and uses the address(es) to send subscriber-related messages to the allocated application server. | 09-25-2008 |
| 20080319948 | Xml Document Manager Server Method and Apparatus - A method is disclosed of providing an XML Document Manager Server function to an XML Document Manager Client ( | 12-25-2008 |
| 20100023417 | METHOD AND ARRANGEMENT FOR PROVIDING SECURITY FOR CONTENT PURCHASES - A method and arrangement for providing security when an IMS client purchases content from a content or service provider, the IMS client having a unique IMS identity registered with a first IMS operator. A second IMS operator assigns a unique IMS identity to the content or service provider which is authenticated based on the assigned IMS identity. The validity of the IMS client is then verified towards the content or service provider, based on a mutual interconnect agreement between the first and second IMS operators, in response to a purchase request from the IMS client. The content or service provider can then also be validated towards the IMS client. | 01-28-2010 |
| 20100118860 | METHOD AND ARRANGEMENT FOR ALLOWING ENTERPRISE AND PERSONAL DOMAINS IN THE IMS - The present invention relates to a method and an arrangement for allowing private domains in the IMS, which makes it possible to use a SIP URI like ID@private-domain.TLD. This is achieved by providing an administration support and an interface to the IMS interconnect DNS and the DNS system of the operator network. The identity associated with private domain is established as a Private domain name based IMPU. The private domain name based IMPU and the Operator domain name based IMPU is associated by using the implicit registered identity set provided by the IMS. | 05-13-2010 |
| 20100299420 | METHOD AND ARRANGEMENT IN AN INTERNET PROTOCOL MULTIMEDIA SUBSYSTEM - The present invention relates to a method and an arrangement for allowing private domains in the IMS, which makes it possible to use a SIP URI like ID@private-domain.TLD. This is achieved by providing an administration support and an interface to the IMS interconnect DNS and the DNS system of the operator network. The identity associated with private domain is established as a Private domain name based IMPU. | 11-25-2010 |
| 20110314140 | Capability Query Handling in a Communication Network - A method and apparatus for handling a Session Initiation Protocol (SIP) OPTIONS capability query message in a communication network. A SIP proxy node receives a SIP OPTIONS message from a querying node. It sends the message to a plurality of devices, and receives a response from at least two of the plurality of devices. Each response includes an identity of the responding device and an indication of the capabilities of the responding device. Each received response is stored in a memory, and a reply message is generated. The reply message includes the identities and capabilities of all of the responding devices. This reply message is then sent to the querying node. This allows the querying node to receive capability information relating to all of the callee's devices rather than just the one that responds first. | 12-22-2011 |
