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.

IMS conferencing policy logic

A method provides callback services in a communications system to a first party from a second party. The method includes supplying the second party with a telephone number of the first party in a first format. The method also includes selecting a numbering plan out of plurality of numbering plans based on at least one of the country and network where the second party is located. The method also includes converting the telephone number from the first format to a second format using the selected numbering plan.

Callback services in a communication system

A method of establishing a conference call in a communication network between a plurality of user terminals each having an identifier. The method comprising receiving a first list of identifiers corresponding to the user terminals with whom the conference call is to be established. At least one of the identifiers represents a second list comprising a plurality of other user terminals each having their own other identifiers. The conference call is established with the user terminals in the first list and the other user terminals represented by the at least one identifier in the first list.

A method and apparatus for providing multi-client support in a SIP-enabled terminal involves providing a SIP processing stack on the terminal. The clients connect to the SIP processing stack to communicate client capabilities and to process SIP messages. The SIP processing stack sends and receives SIP messages. Incoming SIP messages are sent to the appropriate client by looking at the client capabilities and the data in the SIP message.

A system, apparatus and method for releasing sessions via network entities associated with the session, where the network entities include at least session endpoints and intermediary network entities. Network entities are subscribed to intermediary network entities serving as notifiers. Upon releasing the communication session at a first notifier, a session release notification is initiated from the first notifier to its respective subscriber. The session release notification is logically advanced towards a remote one of the session endpoints via the intermediary network entities. The communication session is terminated at each of the network entities receiving the session release notification.

A system, apparatus, and method for routing communication requests based on user presence information. A network entity subscribes to the presence information of a user, and receives notifications of the users' presence information when the user has registered with the network or the presence information has changed. In response, the network entity creates routing instructions based on the presence information. In this manner, incoming communication requests can be appropriately routed according to the routing instructions.

A method and apparatus for providing multi-client support in a SIP-enabled terminal involves providing a SIP processing stack on the terminal. A SIP processing stack listens on multiple ports of a network interface. Each port is associated with a client application. The SIP processing stack sends and receives SIP messages for the client applications. Incoming SIP messages are sent to the appropriate client by looking at the port at which the SIP message was received.

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.

Optimal location service for managing next hop addressing for messages associated with multiple address schemes

A method for use by an I-CSCF () in resolving an address of a message according to SIP but using a protocol-agnostic scheme, and corresponding equipment. The method includes: a step () of querying a data store () 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 () to find the S-CSCF () for the target user () if the target user is an IMS client, or for forwarding to a gateway or next hop in the path to the target user () if the target user () is not an IMS client; and a step () 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 () of addresses.
