Embodiment 1

[0039] In this embodiment, the information identifying the time-shifted television service establishment request is the service identifier of the time-shifted television service, and the SCF judges whether the session modification request is a time-shifted television service establishment request according to the service identifier in the session modification request.

[0040] image 3 It is a flowchart of a method for establishing a time-shifted television service in a BC according to Embodiment 1 of the present invention. like image 3 As shown, the method includes the following steps:

[0041] The process of establishing a BC service is the same as that of the prior art, and will not be repeated here.

[0042] Step 300: The UE sends a session modification request carrying a service identifier to the SCF by using the invite (reInvite) of the SIP protocol.

[0043] In this step, the UE sends a session modification request message to the SCF through the Core IMS. In order ...

Embodiment 2

[0054] In this embodiment, the information identifying the time-shifted TV service request is a newly defined header field, and the SCF judges whether the session request message is a time-shifted TV service establishment request in BC according to the newly defined header field carried in the session modification request.

[0055] Step 400: The UE uses a reInvite message of the SIP protocol to send a session modification request carrying a newly defined header field to the SCF.

[0056] For example, the newly defined Iptv-Service-Type: TsTV header field in the SIP message indicates that the session modification request message is a request for establishing a time-shifted TV service in BC.

[0057] Step 401: The SCF determines that the session modification request is a time-shifted television service establishment request according to the newly defined header field in the reInvite message.

[0058] For example, the UE and the SCF can identify the header field Iptv-Service-Typ:...

Embodiment 3

[0065] In this embodiment, the SCF judges that the session request message is a time-shifted television service establishment request according to the unicast media description information carried in the session modification request.

[0066] Figure 5 It is a flowchart of a method for establishing a time-shifted television service in a BC according to Embodiment 3 of the present invention. like Figure 5 As shown, the method includes the following steps:

[0067] Step 500: UE sends a session modification request carrying its unicast media description information to the SCF by using a reInvite message of the SIP protocol. The port number in the unicast media description information carried therein is not 0, indicating that this is a newly added unicast media stream.

[0068] In this step, the unicast media description information is carried through the media line information described in the Session Description Protocol (SDP, Session Description Protocol) of reInvite.

Abstract

The invention discloses a method used for establishing a time-shift television service in a broadcast service, comprising the steps as follows: firstly, a service control function (SCF) receives the conversation modification request sent by user equipment (UE); wherein, the request carries along the information which identifies the time-shift television service establishment request; when the SCF judges that the conversation modification request is the establishment request of the time-shift television service according to the information used for identifying the time-shift television service establishment request, the establishment of the time-shift television service is carried out. The invention also discloses a system used for establishing the time-shift television service in a broadcast service and a SCF entity. The method, the system and the SCF entity lead the SCF to issue the establishment of the time-shift television when judging the received conversation modification request is the establishment request of the time-shift television service, thus achieving the normal establishment of the time-shift television service.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method, system and device for establishing a time-shifted television service in a broadcast service (Broadcast Service). Background technique [0002] IPTV is a brand-new technology that utilizes broadband cable TV network and integrates Internet, multimedia, communication and other technologies to provide home users with a variety of interactive services including digital TV. IPTV uses Transmission Control Protocol / Internet Protocol (TCP / IP) as the bearer protocol to carry out unicast, broadcast or multicast video services, effectively combining the three fields of TV network, telephone network and Internet, and is the most comprehensive solution for the integration of the three networks. representative business. [0003] IP Multimedia Subsystem (IMS, IP Multimedia Subsystem) is an IP-based standard system independent of access technology. IMS and existing voice and da...
