Abstract: A method and system for deactivating a service account associated with an application server of a registered subscriber within a signaling network supporting IP based services is disclosed. A status of the service account is monitored, and a request for de-registration or barring is forwarded to a registration server, which maintains a registration status and barring indication of said subscriber, e.g. over an interface directly coupling the application server and the registration server upon determining that disruption or termination of service is required. The registration status of the subscriber is then changed so as to de-register the subscriber at the registration server in response to the de-registration request or, respectively, the barring indication of the subscriber is then changed so as to bar the subscriber at the registration server by changing the barring indication in response to the barring request.

Abstract: A method of multiplexing different sessions using the same authorized contexts for media, comprising: distinguishing the sessions to be multiplexed, by a device; creating a new session on a control plane; indicating media flows of different sessions; and enabling the sessions to share the same authorized context for media, thus being multiplexed.

Abstract: The present invention concerns a method for controlling streaming services between a terminal (UE) and a streaming server (SS) via a communication network, wherein the communication network comprises at least one application server (AS) and a controlling entity (PCF, CSCF), the method comprising the steps of: requesting (1-3) a streaming session by said terminal at said application server, negotiating (4-8) streaming session details between the application server (AS) and the streaming server (SS), informing (9-10) the controlling entity (PCF) of the result of negotiating, and creating (11), at said controlling entity (PCF), authorization information for the requested streaming session, and supplying (14) access nodes (GGSN) of the communication network with the authorization information.

Abstract: A method and system locates a mobile terminal addressed in a location service request by an overlay identity. A location service client accesses a first subscriber database, thereby providing an overlay identity, in order to derive a cellular identity of said mobile terminal. The location service client then may use the cellular identity to request a location service from a location service server to enhance their functionality.

Abstract: In order to enable a home network operator to also control the issuing of certificates to a roaming subscriber, first information indicating whether or not it is allowed to issue a certificate to the subscriber is maintained in the subscription information. The first information is checked in response to a subscriber's certificate request received from the subscriber and the certificate is generated and delivered to the subscriber only if certificate issuance is allowed.

Abstract: A method and system for resetting nodes in a communication system that include at least a first node and a second node. The establishment for communication settings is initiated between the first node and the second node. At least part of communications settings is stored in the first node. An indication is sent from the second node to the first node to reset the stored communication settings in the first node. The communication settings are reset in the first node.

Abstract: The invention relates to a method and system for enabling a callback from an entity to an equipment initiating a session wherein nodes involved in handling the session, are adapted to store information for the session, preferably for a predetermined time from the beginning of the session. The information includes an address of at least one other node in the signalling path, and may also include an identity of the equipment. The at least one other node will be used, in case of callback, to carry signalling related to callback from the entity to the equipment. Preferably, signalling bearer for establishing the session is maintained for a certain time from the beginning of the signalling bearer activation. The nodes preferably are IMS nodes and include P-CSCF, S-CSCF, or MGCF node.
