The method comprises sending a subscribe message for an event from the second entity to the first entity, wherein the event is a change in the registration information of at least one of the plurality of users at the first entity; receiving at the first entity a register message from at least one user, said message changing the registration information of said at least one user; sending a notification from the first entity to the second entity in response to the register message, wherein the notification includes information associated with said at least one user.

Abstract: Application-layer signaling of a packet data network, such as the Session Initiation Protocol (SIP), is used to communicate with an interworking interface between the packet data network and a circuit-switched network, particularly a public land mobile network (PLMN), wherein the interface converts the application-layer signaling of the packet data network to a control protocol utilized in the PLMN, wherein a private user identification is carried, for example, by means of a Session Description Protocol (SDP) within the application-layer signaling between the packet data network terminal and the interface, and wherein standardization of lower layers of the packet data network protocol stack is not required beyond that which is already defined. The interface between the packet data network and the circuit-switched network provides the private user identification to the circuit-switched network in the manner in which the circuit-switched network is accustomed.

Abstract: The present invention is a system and method which provides authentication for data services for at least one UE (12) using common authentication information based upon information stored in a HSS (16) of a home network (20) of the at least one UE for multiple protocols. At least one proxy server (18) stores authentication information for each of the protocols which may be used to provide data services to the at least one UE. Authentication of the protocols available to the least one UE uses the authentication information stored at the at least one proxy server obtained from the protocol used in the home network of the at least one UE.

Abstract: A system, apparatus, and method is disclosed for providing media session descriptors. In accordance with one embodiment of the invention, a method of initiating a multimedia session via a computing arrangement involves forming a request for a session descriptor usable for initiating the multimedia session. The request is communicated to a session descriptor module of the computing arrangement. A session descriptor is formed based on a set of multimedia session parameters of the computing arrangement. The session descriptor is communicated from the session descriptor module, and the multimedia session is initiated using the session descriptor.

Abstract: A system, apparatus, and method are disclosed for providing quality of service (QoS) for a network data connection. The network data connection uses a network protocol selectable from a plurality of network protocols. A QoS module can receive a request for a generic QoS and apply this to the network protocol using a specific QoS associated with the protocol. The QoS module may include features for automatic management of QoS and a user interface for changing data connection parameters.

Abstract: Generic Internet Protocol (IP) authentication is provided by authentication server (134). Application Programming Interface (API) (310) detects the protocol type of an incoming authentication request and invokes one of a number of authentication mechanisms (318-326) depending on the protocol type detected. A localized repository (520) is provided to store Subscriber Identity Module (SIM) information and other algorithm data as required to facilitate the authentication session.

Abstract: A method, apparatus, and system are disclosed for creating a conferencing access logic. The logic is for allowing access to a conference in an internet protocol (IP) network. The invention entails establishing an allow list of allowed users, setting up a default policy applicable to unlisted users, matching listed users with corresponding conference rights, and assigning a uniform resource identifier (URI) to the access logic. The URI is for identifying and editing elements of the access logic, including the allow list, the default policy, and the conference rights.

Abstract: A method for use by an I-CSCF (12b) in resolving an address of a message according to SIP but using a protocol-agnostic scheme, and corresponding equipment. The method includes: a step (32) of querying a data store (12c) of scheme mappings, in response to receiving such a request, the querying for determining possible mappings to trial schemes at least one of which resolves the address, i.e. which can be used by the I-CSCF (12b) to find the S-CSCF (12e) for the target user (11b) if the target user is an IMS client, or for forwarding to a gateway or next hop in the path to the target user (11b) if the target user (11b) is not an IMS client; and a step (33) of testing in turn (until success or until all possible trial schemes are tested) each possible trial scheme, the testing based on comparing an address using the trial scheme with an address in a data store (12d) of addresses.

Abstract: A method and corresponding equipment for setting up a conference call via a communication network that uses session initiation protocol (SIP) signalling for call setup, the method including steps (E1a E2a E3a E4a) of providing during the call setup signalling to a subscriber invited to participate in the conference call an indication that the call is a conference call and including in the call setup signalling a reference to a group document indicating information about the conference call, such as the other invited participants, or including the group document itself.

Abstract: A system and method for managing next hop addressing where multiple address schemes are provided in messages transmitted via a network. A predefined addressing policy may be applied to an incoming message if the predefined addressing policy includes a policy corresponding to an incoming address scheme of the incoming message. The incoming address scheme is converted to one or more outgoing address schemes provided by a location service in response to a location query. A plurality of outgoing messages is dispatched, each using one of the outgoing address schemes provided by the location service. A default next hop addressing operation is effected when the predetermined addressing policy does not correspond to the incoming address and when none of the multiple outgoing address schemes provides a useful result.

Abstract: A method and apparatus for dispatching incoming application data on a computing device is disclosed. A dispatcher can determine a correct destination application for an incoming application data based on a registry and an application descriptor in the incoming data. In one arrangement, the dispatcher can be included as part of the Java Mobile Device Information Profile PushRegistry framework for handling incoming network connections. The dispatcher can be used in a multiple protocol environment, as well be used by multiple applications utilizing the same protocols.

Abstract: A computer-implemented apparatus and method for communicating partial notifications relating to a presentity's presence information. The communication may be effected between presence servers and terminals coupled to the presence servers via a network. At least one presentity is identified to which a terminal has requested presence services. A presence document is created, where the presence document includes presence information corresponding to the presentity. The presence information is configured as partial presence information comprising less than a total of the presence information available for the presentity. The presence document having the partial presence information is communicated to the terminal requesting the presence information.

Abstract: A method (and corresponding equipment) by which a first device (11a), operable in a first network (11) including an SIP type of network (such as an IMS network) to which the first device (11a) is subscribed, communicates with a second device (12a), operable in a second network (12) including a WV network to which the second device (12a) is subscribed, the method providing routing steps so that each SIP network entity, such as an I-CSCF (11f), that processes the message encounters an SIP addressing scheme, i.e. the addressing scheme native to the SIP type of network, and so that each WV server (12b) encounters only an addressing scheme native to the WV network, after possibly preliminary conversion (A0-D0) to the native addressing scheme. The first network (11) may also include components of a WV network, and the second network (12) may also include components of an SIP type of network.

Abstract: A method and apparatus for updating authorization and other persistent data using the session initiation protocol. In one aspect, a computing device sends a SIP PUBLISH message (or any other appropriate SIP message) to a second networked computing device. The second device extracts data from the SIP message and uses the extracted data to modify and/or update a set of persistent data. The data may be placed in the body of the SIP message. In one example, the SIP message body uses XML enclosing a remote procedure call or a call processing script.

Abstract: A method and system of providing group management for IMS conferencing services involves creating side control channels for membership control services. The membership control channel can use Client Group Management Protocol (CGMP) or alternate group management protocols. The membership channel can use HTTP, SIP, or other transport protocols. Group management protocol primitives and procedure calls can be communicated using SOAP or other XML-based protocols.

Abstract: Mapping functionality is added in between a Wireless Village (WV) server and a Presence, Messaging and Group (PMG) server of a 3GPP IP (Internet Protocol) Multimedia Subsystem (IMS) to permit interoperability between WV and IMS clients for instant messaging and presence services for operators who have deployed both IMS and WV. Due to the possibility that an operator may have deployed WV but not IMS and due to the use of a Client-to-Server Protocol (CSP) between WV clients and WV servers and the use of a Server-to-Server Protocol (SSP) between WV servers, the mapping functionality is structured to permit an IMS device to register into WV system via an IMS/WV Relay that performs an SIP/CSP conversion to emulate a WV device login but to then use the SSP to maintain a session or to deliver a message or presence information. Likewise, a WV device can register directly into IMS for operators not deploying WV using the mapping functionality of the present invention, e.g., in an IMS/WV Relay.

Abstract: A method, and related equipment, for interoperating between a device (11a) in a first network, such as an IMS network, and a device (12a) in a second network (12), such as a WV network, the first network using a first protocol (SIP) requiring that a message have a request uniform resource identifier including an address scheme, and the second network (12) using one or more other protocols. The method includes a step (41) of converting a message constructed according to the first protocol (SIP) but having as an address scheme indicating a protocol of the second network (such as “wv:”) to a message in which the address scheme is changed (e.g. to “sip:”) to indicate the protocol of the first network and in which a user uniform resource locator parameter is provided having a value indicating the original scheme, before conversion (i.e. “wv” in the example given).
