Abstract
A network element for handling a trusted relationship in an IP multimedia subsystem, the network element includes a receiving unit for receiving a message from another entity, wherein the message includes a header. The network element also includes a determining for determining that an entity from which the message is received is a predefined trusted entity. The header of the message includes information for identifying whether or not the entity from which the message is received is a predefined trusted entity. The network element also includes a processing unit for using contents of the header, from the entity that is determined to be a predefined trusted entity, for applications implemented by the network element.
Claims20
A network element for handling a trusted relationship in a Session Initiation Protocol network, the network element comprising:
- a receiving unit for receiving a message from another entity, wherein the message includes a header and at least one trust token;
- a determining unit for determining that an entity from which the message is received is a predefined trusted entity, wherein the header of the message comprises information for identifying whether or not the entity from which the message is received is a predefined trusted entity;
- and
- a processing unit for using contents of the header, from the entity that is determined to be a predefined trusted entity, for applications implemented by the network element.
A method for handling a trusted relationship in a Session Initiation Protocol network, the method comprises the steps of:
- receiving a message from another entity, wherein the message includes a header and at least one trust token;
- determining that an entity from which the message is received is a predefined trusted entity, wherein the header of the message comprises information for identifying whether or not the entity from which the message is received is a predefined trusted entity;
- and
- using contents of the header, from the entity that is determined to be a predefined trusted entity, for applications implemented by the network element.
An apparatus for handling a trusted relationship in an Session Initiation Protocol network, the apparatus comprising:
- receiving means for receiving a message from another entity, wherein the message includes a header and at least one trust token;
- determining means for determining that an entity from which the message is received is a predefined trusted entity, wherein the header of the message comprises information for identifying whether or not the entity from which the message is received is a predefined trusted entity;
- and
- processing means for using contents of the header, from the entity that is determined to be a predefined trusted entity, for applications implemented by the network element.
An apparatus for sending a message to an entity with a trusted relationship in a Session Initiation Protocol network, the apparatus comprising:
- a generating unit for generating a request including a message with at least one trust token;
- and
- a transmitting unit for transmitting the request to an entity with a trusted relationship, wherein the entity comprises receiving means for receiving the message, wherein the message includes a header and the at least one trust token, determining means for determining that the apparatus from which the message is received is a predefined trusted entity, wherein the header of the message comprises information for identifying whether or not the apparatus from which the message is received is a predefined trusted entity, and processing means for using contents of the header, from the apparatus that is determined to be a predefined trusted entity, for applications implemented by the entity.
