Embodiment Construction

[0011] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to preferred embodiments in conjunction with the accompanying drawings.

[0012] figure 1 It exemplarily shows the network bearer structure of the VOIP service. Such as figure 1 As shown, the network structure for performing VOIP services mainly includes a softswitch platform, a business border control device (BAC), a home gateway, a SIP phone, and a soft terminal. Among them, the softswitch platform mainly performs service authentication, authorization and call processing. The service border controller is mainly used as the signaling firewall of the softswitch service, the traversal of private network users, and the media agent. The home gateway is mainly responsible for completing the network access function. SIP phones and soft terminals are service terminals, responsible for initiating an...

Abstract

The invention provides a service control method of a VOIP service, a VOIP service terminal identification and control method. The VOIP service terminal identification and control method comprises the following steps: an applied terminal sends a login request of a soft switch network to a service boundary control apparatus (BAC); the service boundary control apparatus identifies the applied terminal according to applied terminal information carried by a special domain in a received login request; and the service boundary control apparatus realizes a control strategy of the VOIP service based on the terminal identification, wherein the BAC executes two additional judgments in performing a process of service register at the terminal, namely access IP identification and terminal identification, thereby realizing judgment on applied terminal access points, access operators and terminal customization information. The method of the invention is convenient for the operator to develop the service strategy binding when development of the VOIP service.

Description

technical field [0001] The invention relates to the field of Internet applications, in particular to VoIP (VoIP) services. Background technique [0002] At present, VoIP basic services based on softswitches have matured, among which softswitch platforms, Business Access Controller (BAC: Business Access Controller), home gateways, SIP phones and soft terminals are the main network elements of VoIP basic services. Among them, the softswitch platform mainly completes service authentication, authorization and call processing. The service border controller is mainly used as the signaling firewall of the softswitch service, the traversal of private network users, and the media agent. The home gateway is mainly responsible for completing the network access function. SIP phones and soft terminals are service terminals, responsible for initiating and responding to VOIP service calls. [0003] In the prior art, IP layer access is not associated with service layer registration and c...
