Description
Technical field
The present invention relates to network control management system and method, more particularly, relate to WiMax network control management system and method.
Background technology
IEEE 802 has worked out different standards in wireless domain at the different market demands and application model, as is applied to IEEE 802.11 standards of WLAN (wireless local area network).802.16 of IEEE are for working out the working group that wireless MAN (English Wireless MAN) standard is set up, this working group after setting up in 1999, the main air-interface standard of being responsible for fixed wireless access, since the 802.16e task groups establishment of supporting mobility and after much WiMAX joins in main flow equipment manufacturers, IEEE 802.16 has attracted increasing sight.
The main task of IEEE 802.16 is, development also has uniformity test relevant with air interface protocol and the coexistence standard between the different radio connecting system simultaneously in the wireless access system air interface physical layer (english abbreviation PHY) and medium access control layer (english abbreviation MAC) standard of 2～66GHz frequency band.
The wireless system of IEEE 802.16 regulations is mainly used in metropolitan area network, and present 802.16 comprise two main flow air-interface standard: 802.16d and 802.16e, is respectively fixing and moves design.
802.16d and the protocol stack model of 802.16e standard as shown in Figure 1.Air interface is made up of PHY and MAC layer, the MAC layer has been divided into three sublayers again: special services convergence sub-layer (English ServiceSpecific Convergence Sublayer, abbreviation CS), common unit sublayer (English Common Part Sublayer, abbreviation CPS), Security Sublayer (English Privacy Sublayer, abbreviation PS).The central role of CS sublayer is to upper layer data classification with to the compression in data packet header; The CPS sublayer is the core sublayer of MAC, and it mainly finishes service flow management, the distribution of bandwidth and scheduling, QOS (service quality) etc.; The effect of PS is to the data encryption and decryption, so that safe transfer of data to be provided.
MAC layer characteristic, 802.16 MAC layers are based on " connection ", i.e. all terminal data service and relevant therewith QOS requirement is based on all that " connection " carry out.Each " connection " comes unique the sign by an identifier (english abbreviation CID).In 802.16 standards, the MAC layer has defined comparatively complete QOS mechanism.The MAC layer can be provided with different QOS parameters respectively at each connection, comprises indexs such as speed, time-delay.
The 802.16g standard of network management aspect, 802.16 system management flow process and interfaces of required standard, thus can realize the interoperability of 802.16 equipment and to effective management of Internet resources, mobility and frequency spectrum.
Be illustrated in figure 2 as the control and the managerial structure schematic diagram of existing 802.16 grids, be to have 802.16 standard operation scope now in the frame of broken lines among Fig. 2, wherein the standard of PHY and MAC part defines in 802.16d and 802.16e, management information bank (English Management Information Base, abbreviation MIB) in 802.16f, defines, the webmaster of movable part will define in the 802.16i of postorder, and the standard of other control and management plane defines in 802.16g.At present at network control management system (English Network Control and Management System, abbreviation NCMS) carries out C_SAP/M_SAP/CS_MAP (English service access point with each layer service access point of 16, the abbreviation SAP) description the time, lack one and distinguish subscriber (English Subscriber Station, abbreviation SS) with the effective way of base station (English Base Station, abbreviation BS).
Be illustrated in figure 3 as World Interoperability for Microwave Access, WiMax (English Interoperability for MicrowaveAccess, abbreviation WiMax) NCMS functional block diagram, NCMS among the figure does not belong to 802.16 critical field, but these business functions all have business or management interface with 802.16 MAC, PHY and management plane.By these interface/access points, the equipment under 802.16 obtains the corresponding business ability.
Along with the IP broadband network in recent years fast development, broadband access technology such as Ethernet insert, ADSL inserts, WiFi (Wireless Fidelity, Wireless Fidelity) routine work, the life of going deep into people such as insert, many public places such as Internet bar, coffee shop, waiting room, boarding lounge, exhibition provide various access waies for people.
Because the assurance of high bandwidth, for many main frames provide possibility, present customer premises equipment, CPE end (English Custom Premier Equipment at ADSL, abbreviation CPE) user side that can form a client network, Ethernet also can be formed a LAN, after WiMAX occurs, the demand of many main frames still exists, and compare with existing fixing with the WiFi access technology, the residence network of WiMax (English full name customer premises network, abbreviation CPN) network further needs to support switching, roaming to guarantee service intercommunication.
When the SS side has a plurality of main frames (Host), present standard does not have relevant solution and definition, what can adopt is more direct simple IP access way, when main frame inserts, obtain IP (DHCP or PPPOE) from this locality, and obtaining the access rights of network by the mode of inlet (Portal) authentication, this is with WiFi is basic identical in the access way that various public places use at present.But because the whole access procedure of main frame does not have and any message takes place registered place (Home), the business intercommunication that therefore also is far from being, it certainly exists professional discontinuous problem.Prior art does not have between strict difinition SS and the NCMS (SS side) and the network management plane between BS and the NCMS (BS side), causes the NCMS network function fuzzyyer; And lack the solution of SS side as residence network, when the SS side joint is gone into a plurality of main frame, there are not complete set technology and standards such as corresponding access control, authentication and accounting, network switching
