Description
Technical field
The present invention relates to network communications technology field, relate in particular to a kind of distributed conversation edge control device, system and method.
Background technology
In NGN (next generation network) network architecture of ETSI TISPAN (normal structure in an Europe) definition; Between application layer and transport layer, introduced RACS (Resource and Admission Control Sub-system); Be used for the resource of unified management bearer network, and dialogue-based and tactful dynamic QoS (quality of service) control is provided.In the NGN network architecture of ETSI TISPAN definition, also defined NASS (Network Attachment Subsystem).
In the NGN network architecture of ETSI TISPAN definition, the function structure of RACS and NASS is as shown in Figure 1, and RACS mainly comprises: SPDF (business game decision making function entity) and Access-Resource and Admission Control Function (accommodating access resource controlled function entity); RACS and NASS are through the interconnection of e4 interface; Wherein,
The major function of SPDF comprises: adopt the policing rule based on business to carry out the strategy decision: receive the resource request of AF (Application Function) and according to local policy, and with the interaction results of Access-Resource and Admission Control Function and BGF (Border Gateway Function entity) resource request that AF sends is authorized.
The major function of Access-Resource and Admission Control Function comprises: be responsible for the admittance control of access-in resource, specifically comprise: the resource request of the policy deciding functional entity of accepting business, and carry out resource and admission according to QoS subscription data that accesses terminal and resource operating position and control; And, carry out obtaining the QoS subscription data that accesses terminal alternately with NASS; And control RCEF (Resource Control Enforcement Function entity) and Access Node (access node) accomplish the enforcement of qos policy.
The QoS control point that defines among the RACS at present has three: first is BGF, and RACS issues Flow Policy through Ia interface, and control BGF accomplishes the QoS controlled function of this point; Second is RCEF, and RACS is according to the topological structure and the resource operating position of Access Network, and whether decision allows new session to insert, and issues Flow Policy through the Re interface, and control RCEF accomplishes the QoS controlled function; The 3rd is Access Node, and RACS accomplishes the QoS controlled function through Ra interface control Access Node.
The function structure of existing NASS is as shown in Figure 2, comprising: ARF (insert transfer functional entity), AMF (access management function entity), NACF (network access configuration function entity), be used to carry out IP (network layer protocol) address dynamic assignment DHCP (DynamicHost configuration feature entity), be used to carry out the user location CLF (connectivity session positioning function entity), be used to carry out the UAAF (user access authorization function entity) of network insertion mandate and authentification of user.
The CNGCF (ustomer premises access equipment CPE configuration feature entity) that also comprises following peripheral entity: PDBF (user-subscribed database functional entity) in the function structure of NASS, is used to carry out CPE (customer premises equipment, CPE or terminal) configuration.
Existing session margin control, promptly the equipment form of SBC (session margin control) is as shown in Figure 3, comprising: BC (margin control) and ABG (access Border Gateway).Wherein, this BC comprises: P-CSCF (Proxy Call Session Control Function) entity and the A-SPDF (inserting SPDF) that is divided into by SPDF; This ABG comprises: Access Border Gateway Function (inserting BGF) and RCEF functive.A-SPDF links to each other with the C-SPDF (core SPDF) that is divided into by SPDF that is positioned at core net.This SBC is arranged in Access Network, and Access-Resource and Admission Control Function separates with AN (access node), and connects through Rq.
In realizing process of the present invention, the inventor finds: there are a lot of shortcomings in existing SBC equipment form, specifically comprises:
The first, for the situation (such as WiMAX (broadband wireless access)) of wireless access, do in the base station usually and admit control, if adopt existing independently resource control appliance, then can not satisfy the functional requirement of Access-Resource and Admission Control Function;
