Method for advertising in IP multimedia subsystem and server and terminal thereof

摘要

Disclosure may be to allow a Service Provider (or operator) to intercept SIP messages (e.g., SIP INVITE method, or SIP MESSAGE method) in the path of the IMS signaling link and insert advertising information therein, thereby delivering the advertising information inserted in the SIP messages to one or more end users (i.e., originating end or terminating end, or all of them).

主权项

1. A method for advertising in an IP Multimedia Subsystem (IMS), the method comprising:
receiving, by a first entity, a first message toward a target terminal, the first message originated by a source terminal, wherein the first message has contents for a first session between the source terminal and the target terminal; sending, by the first entity, the first message to a second entity, wherein the first message is intercepted in a path of the IMS signaling link by the second entity; receiving, by the first entity, from the second entity the first message including first advertising information, wherein the first advertising information is inserted into the intercepted first message by the second entity; and sending, by the first entity, to the target terminal the first message having the first advertising information, wherein, during the first session, a second session is established between the second entity and the source terminal by exchanging a third message transmitted from the second entity to the source terminal and a fourth message transmitted from the source terminal to the second entity in response to the third message, and a third session is established between the second entity and the target terminal by exchanging the third message transmitted from the second entity to the target terminal and the fourth message transmitted from the target terminal to the second entity in response to the third message, and wherein second advertising information is transmitted from the second entity to the source terminal via the second session, and third advertising information is transmitted from the second entity to the target terminal via the third session.
