摘要:
A method is disclosed of providing an XML Document Manager Server function to an XML Document Manager Client (2-1). The XML Document Manager Server function is enabled by a database component for storing at least one XML document and a logic component for causing at least one operation to be performed on one or more of the at least one XML documents. In the method, the logic component is provided by a first network entity (60-1), with which the XML Document Manager Client (2-1) communicates directly or indirectly to receive the XML Document Manager Server function, and the database component is provided by a second network entity (70) different to the first network entity (60-1).
摘要:
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.
摘要:
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.
摘要:
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.

摘要:
A method of registering or deregistering a user to or from an IP Multimedia Subsystem (IMS) network. A SIP Application Server (SIP-AS) performs a registration or deregistration with the IMS network on a user's behalf. The registration or deregistration is performed over one of the following interfaces: a Service Control Interface (ISC) with a Serving Call State Control Function (S-CSCF), a Gm interface with a Proxy CSCF (P-CSCF), or an Ma interface with an Interrogating CSCF (I-CSCF).
摘要:
Methods and apparatus facilitate recovery of an IMS in which an S-CSCF has suffered a restart (after a failure, software upgrade, or other reasons). One or more of first and second methods comprise submitting, from the S-CSCF towards a HSS, contact data required by the S-CSCF to contact a given subscriber, or to contact a proxy server through which the subscriber is accessible; storing the contact data at the HSS; and providing from the HSS towards an IMS entity, which may be previously assigned S-CSCF or a new S-CSCF, contact information elements selectable from the contact data.
摘要:
A method and communications network node for allocating a priority level to an Internet Protocol (IP) packet containing all or part of a Session Initiation Protocol (SIP) message. One or more characteristics of the SIP message are determined, and the characteristics are mapped to a Differentiated Services Code Point (DSCP) value. The DSCP value is then applied to the IP packet header.
摘要:
A Home Subscriber Server for handling IP Multimedia Subsystem subscriptions comprises means for maintaining associations between public user identities and Service Profiles, where two or more public user identities can be associated with a common Service Profile, and means for identifying to a network node all public user identities that are associated with a common Service Profile.
