Abstract: The present invention relates to a method usable for managing a connection release of an established connection between two or more parties via a communication network. When the reason for terminating a connection/session between at least two parties is caused by circumstances in the communication network, such as a loss of bearer, this is detected in a first network element. Then the first network element generates a connection terminating message to be used in the connection release procedure into which a new information element is introduced indicating the reason for the connection release, for example the loss of bearer. This reason may be indicated to a user as an optional and additional information. Furthermore, a corresponding system, device and/or terminal equipment are proposed.

Abstract: The invention proposes a method for routing sessions in a Session Initiation Protocol (SIP) used in a communication system, comprising the step of using a Globally Routable User Agent Uniform Resource Identifier (GRUU) for identifying the instance, wherein the Globally Routable User Agent Uniform Resource Identifier (GRUU) is related to a serving network control element of the instance. By this GRUU, a user equipment can be uniquely identified and a session can reliably be routed via the serving network control element such as an S-CSCF to the user equipment.

Abstract: This invention relates to a SIP and SDP protocols. The idea of the invention is to modify SDP descriptions included in SIP messages to facilitate transcoding. After receiving an INVITE message from a calling party, the SIP proxy negotiates with a transcoder for getting a list of codecs of the transcoder and their address information. The SIP proxy adds the codec list of the transcoder to the received SDP description in the invite message, and sends this way modified SDP description in an INVITE message to a called party. After receiving the modified SDP, the called party selects codecs or a list of suitable codecs according to preferences in the modified SDP and its own preferences.

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 and system forwards a service-related information to network user, wherein at least one new event package directed to a service configuration and/or a de-registration state of the network user is provided at a session control device or a default server or an application server, respectively.
