Abstract:
1. A method for realizing a Broadcast TV (BTV) service, comprising: subdividing, by an Internet Protocol Television (IPTV) server, total BTV service to be consumed into different BTV service packages, and allocating 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; sending, by the IPTV server, the BTV service package IDs to a User Equipment (UE) and a network edge device corresponding to the UE; configuring, by an operator device, channel program content of each BTV service package in the network edge device; receiving, by the IPTV server, 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; sending, by the IPTV server, 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; establishing, by the IPTV server, the first session between the IPTV server and the UE to perform charging to the first channel program; receiving, by the network edge device, a first IGMP JOIN message from the UE; and searching, by the network edge device, the first channel program in the first BTV service package, and sending 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 are performed by the IPTV device, and sending the association ID to the network edge device so as to associate an IGMP request of the UE with a BTV service package that corresponds to the association ID.
