Abstract
A method and device for obtaining media description information of Internet Protocol Television (IPTV) services are provided. The method includes: receiving, by a network device, a Session Initiation Protocol (SIP) request for obtaining media description information, where the SIP request is sent by a User Equipment (UE) through a core IP Multimedia Subsystem (IMS) and carries a content identifier; sending, by the network device, a SIP response that carries the media description information corresponding to the content identifier to the UE through the core IMS. According to the present disclosure, a SIP message is used to obtain media description information, so that a session of the Content on Demand (CoD) service is set up.
