         6 . The method according to  claim 5 , 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. 
     
     
         7 . The method according to  claim 1 , further comprising: reserving corresponding bandwidth resources for the BTV service package according to bandwidth information, the BTV service control information comprising the bandwidth information of the BTV service package. 
     
     
         8 . The method according to  claim 1 , further comprising: monitoring a session, and controlling the network edge device to abort an authorization on the BTV service package of the UE when the session is interrupted. 
     
     
         9 . The method according to  claim 8 , wherein the interruption of the session is caused by at least one of UE power off, a UE failure, and a session abortion requested by the UE. 
     
     
         10 . An IPTV server, comprising:
 a searching unit adapted to query a related BTV service package according to indication information corresponding to a BTV service package in a received session establishment request, wherein the BTV service package comprises a plurality of channel programs sharing an authentication attribute and a charging attribute; and   a control unit adapted to obtain BTV service control information according to a searching result generated by the searching unit, and send the BTV service control information to a network edge device of a UE.   
     
     
         11 . The IPTV server according to  claim 10 , further comprising: a charging unit adapted to charge each of the plurality of channel programs watched by a user according to the charging attribute during a session. 
     
     
         12 . The IPTV server according to  claim 10 , further comprising: a converting unit adapted to convert a UE ID carried in the BTV service control information into an association ID. 
     
     
         13 . The IPTV server according to  claim 10 , further comprising: a detecting unit adapted to monitor a session and sending a detection result to the control unit; wherein the control unit controls the network edge device to abort an authorization on the BTV service package of the UE when the session is interrupted. 
     
     
         14 . A policy/resource control server, comprising:
 a service unit adapted to receive BTV service control information corresponding to a BTV service package, wherein the BTV service package comprises a plurality of channel programs sharing an authentication attribute and a charging attribute;   a converting unit adapted to convert a UE ID carried in the BTV service control information into an association ID; and   a sending unit adapted to send the BTV service control information carrying the association ID to the network edge device.   
     
     
         15 . The policy/resource control server according to  claim 14 , further comprising:
 a resource admission control unit adapted to reserve corresponding bandwidth resources for the BTV service package according to bandwidth information corresponding to the BTV service package.   
     
     
         16 . A network edge device, comprising:
 a service unit adapted to receive BTV service control information of a BTV service package, wherein the BTV service package comprises a plurality of channel programs sharing an authentication attribute and a charging attribute; and   a switching unit adapted to control a service channel in the BTV service package according to the BTV service control information, and send one of the plurality of channel programs to a UE.   
     
     
         17 . The network edge device according to  claim 16 , further comprising: a converting unit adapted to convert a UE ID carried in the BTV service control information into an association ID. 
     
     
         18 . A system for realizing a BTV, comprising:
