- Claim: 2. The method according to claim 1 , wherein when the UE requests to access more than two channel programs belonging to the same BTV service package at the same time, more than two corresponding sessions are established.
- Claim: 3. The method according to claim 1 , wherein the BTV service control information comprises a BTV service package.
- Claim: 4. The method according to claim 1 , further comprising: converting the UE ID into an association ID that is identified by the network edge server, and sending, by the network edge device, the second channel program to the UE; and wherein when the UE requests to access a third channel program in a second BTV service package: sending, by the UE, a second session establishing request for establishing a second session, the second session establishing request carrying indication information for identifying the second BTV service package, sending, by the IPTV server, after authorizing the third channel program in the second BTV service package requested to access by the UE, to the network edge device, BTV service control information for identifying the second BTV service package so as to activate the second BTV service package, establishing, by the IPTV server, the second session between the IPTV server and the UE to perform charging to the third channel program, receiving, by the network edge device, a second IGMP JOIN message from the UE, searching, by the network edge device, the third channel program in the second BTV service package, and sending, by the network edge device, the third channel program in the second BTV service package to the UE.
- Claim: 5. The method according to claim 4 , wherein the association ID comprises at least one of: an IP address of the UE, an ID of a physical port on which the UE exists, an ID of a logic port on which the UE exists and a media access control (MAC) address of the UE.
- Claim: 6. The method according to claim 1 , further comprising: reserving bandwidth resources for the BTV service package according to bandwidth information, wherein the BTV service control information comprises the bandwidth information of the BTV service package.
- Claim: 7. The method according to claim 1 , further comprising: monitoring the session to determine that the session is interrupted, and controlling the network edge device to abort authorization on the BTV service package of the UE when the session is interrupted.
- Claim: 8. The method according to claim 7 , wherein the session is determined to be interrupted when the UE is shut down; the UE fails; or the UE requests to abort the session.
- Claim: 9. An IPTV server, comprising: a memory storing instructions thereon; and processor coupled to the memory and implements the instructions to: subdivide total BTV service to be consumed into different BTV service packages, and allocate a BTV service package ID for each BTV service package, wherein each BTV service package comprises multiple channel programs with the same authorization attribute and the same charging attribute; send the BTV service package IDs to a User Equipment (UE) and a network edge device corresponding to the UE; receive from the UE, a first session establishment request for establishing a first session, the first session establishment request carrying indication information for identifying a first BTV service package, and the first session establishment request requests the IPTV server to establish a session between the IPTV server and the UE in which the UE and the IPTV server know each other's status by periodically sending keepalive packets to each other, wherein the IPTV server realizes authorization and charging functions on the first BTV service package via the first session, and wherein an online state of the UE is monitored in real-time via the first session; send, after authorizing a first channel program in the first BTV service package requested to access by the UE, to the network edge device, BTV service control information for identifying the first BTV service package so as to activate the first BTV service package, wherein the BTV service control information includes a BTV service package ID, a UE ID, and an indication for activating a BTV service package; and establish the first session between the IPTV server and the UE to perform charging to the first channel program, wherein the network edge device receives a first IGMP JOIN message from the UE, searches the first channel program in the first BTV service package, and sends the first channel program in the first BTV service package to the UE; wherein when the UE requests to access a second channel program in the first BTV service package, neither authorization nor charging operations need to be performed by the IPTV server, and sending, by the network edge device, the second channel program to the UE; and wherein when the UE requests to access a third channel program in a second BTV service package: the UE sends a second session establishing request for establishing a second session, the second session establishing request carrying indication information for identifying the second BTV service package, the IPTV server sends, after authorizing the third channel program in the second BTV service package requested to access by the UE, to the network edge device, BTV service control information for identifying the second BTV service package so as to activate the second BTV service package, the IPTV server establishes the second session between the IPTV server and the UE to perform charging to the third channel program, the network edge device receives a second IGMP JOIN message from the UE, the network edge device searches the third channel program in the second BTV service package, and the network edge device sends the third channel program in the second BTV service package to the UE.
- Claim: 10. The IPTV server according to claim 9 , wherein the processor further implements the instructions to: convert an UE IDentification (ID) carried in the BTV service control information into an association ID that is identified by the network edge device.
- Claim: 11. A network edge device, comprising: a memory storing instructions thereon; and a processor coupled to the memory and implements the instructions to: receive BTV (Broadcast TV) service control information for identifying a first BTV service package so as to activate the first BTV service package, wherein the first BTV service package comprises multiple channel programs with the same authorization attribute and the same charging attribute, wherein the BTV service control information includes a BTV service package ID, a UE ID, and an indication for activating a BTV service package; e; receive a first IGMP JOIN message from a UE (User Equipment); search for a first channel program in the first BTV service package; and send the first channel program in the first BTV service package to the UE; wherein when the UE requests to access a second channel program in the first BTV service package, the processor further implements the instructions to send the second channel program to the UE; and wherein when the UE requests to access a third channel program in a second BTV service package, the processor further implements the instructions to: receive BTV service control information for identifying the second BTV service package so as to activate the second BTV service package, receive a second IGMP JOIN message from the UE, search the third channel program in the second BTV service package, and send the third channel program in the second BTV service package to the UE.
