METHOD AND APPARATUS RELATING TO POLICY CONTROL IN A TELECOMMUNICATIONS NETWORK
摘要
<p>A method is provided for use in a telecommunications network. A first message is received (S1 ) at an application function (10). The first message relates to a request for a service involving the establishment of a data flow between a first terminal and a second terminal. The application function (10) is associated with the first terminal for the service. A second message is sent (S3) from the application function (10) to a policy control function (20). The policy control function (20) is associated with the first terminal for the service. The policy control function (20) is assigned to determine at least one policy to be applied to the data flow. The second message comprises first information relating to at least one characteristic of the service that is common with respect to the first and second devices. The second message also comprises second information relating to (a) whether the service is an originating or terminating service with respect to the first terminal, or (b) whether the first terminal is to be considered as an initiator of the service or a recipient of the service; these can be regarded as being equivalent. The second message is received (S4) at the policy control function (20). The second message comprises the first and second information. At least one policy is determined (S5) at the policy control function (20) based on the first and second information received in the second message. A third message is sent (S6) from the policy control function (20) to a gateway node. The gateway node is associated with the first terminal for the service. The gateway node is assigned to enforce at least one policy to the data flow. The third message comprises the at least one determined policy.</p>
