Description
Technical field
The present invention relates to electrical communication technology, relate in particular to a kind of BTS service processing method and system based on WIMAX.
Background technology
Whole world inserting of microwave inter-operation system (WIMAX:World Interoperability forMicrowave Access) is a kind of of WiMAX access technology, and its technical standard is IEEE802.16.IEEE 802.16 has formulated wireless access system air interface physical layer PHY and the medium access control layer MAC standard that works in the 2-66GHz frequency band, also has uniformity test relevant with air interface protocol and the coexistence standard between the different radio connecting system simultaneously.According to whether supporting mobility, IEEE 802.16 standards can be divided into fixed broadband wireless and insert air-interface standard and mobile broadband wireless access air-interface standard, wherein the mainstream standard of the former correspondence is 802.16d, and the mainstream standard of latter's correspondence is and 802.16e.
802.16d and the protocol stack model of 802.16e standard as shown in Figure 1, air interface protocol is made up of Data Control plane and management plane, the Data Control plane is made up of physical layer and medium access control layer MAC, and the MAC layer has been divided into three sublayers again: special services convergence sub-layer (ServiceSpecific Convergence Sublayer), common part sublayer (Common PartSublayer), Security Sublayer (Privacy Sublayer).
The special services convergence sub-layer provides the mapping of external network data to the MAC layer, (CS SAP) is mapped to service data unit (MACSDU) with external network data by the convergence sub-layer Service Access Point, and it is related with MAC traffic stream identifier SFID and connection identifiers CID.
Common part sublayer provides MAC layer core processing function, comprises that system's access, allocated bandwidth, connection are set up, connection is safeguarded.Common part sublayer corresponds in the MAC connection of different qualities by the data of medium access control Service Access Point (MACSAP) reception from special services convergence-level sublayer.
Security Sublayer provides the cipher key change and the encryption function of authentication, safety.
Based on the equipment of WIMAX (IEEE 802.16d/e/f/g) standard development, it constitutes the logical construction that generally can adopt as shown in Figure 2.
WIMAX equipment can be divided into base station (BS:Base Station) and subscriber station (SS:Subscriber Station).
Base station BS is responsible for finishing 802.16 protocol processes and broadband services control generally has several logical process parts such as RF, WIMAXPHY, WIMAX MAC.MAC module and PHY module are finished the processing of the MAC layer and the PHY layer of 802.16 agreements respectively, and radio-frequency module is finished the radio frequency processing of data.
Subscriber station SS is responsible for finishing 802.16 protocol processes, and the access band user data, and SS is distributed in the signal emitter region of BS correspondence.
According to 802.16 agreements, BS is undertaken by being connected with the communication between the SS, need be that each SS disposes SFID on BS before SS inserts, and SFID has defined qos parameter and the resource allocation that is connected between BS and the SS.When SS inserted, BS can dynamically set up with QoS according to the resource of SFID definition and be connected in the air, and corresponding connection identifiers CID is adopted in different connections.
Based on the broadband wireless access equipment of WIMAX standard development, must support support wireless access and broadband services function simultaneously.Under broadband access wireless penetration, mobile trend, along with broadband wireless access use universal day by day, wireless data service will be widely applied.In the tide of global network IPization, two layers of exchange of supported vlans are one of the most frequently used Data Interchange Technology.
Existing base station BS framework as shown in Figure 3, it is made up of the PHY module, MAC module and the radio-frequency module that adopt 802.16 agreements, the rf modulations function that the PHY resume module is wireless, the MAC module can be subdivided into safe submodule, public function submodule, special services according to agreement and converge submodule.Special services converges submodule and finishes the mapping of external network data to the MAC layer, and it is related with MAC traffic stream identifier SFID and connection identifiers CID.
For uplink message, after BS receives message, pass through radio-frequency module, PHY module, MAC module successively, send from upstream Interface.
For downlink message (from BS to the SS direction), BS is according to the mapping relations of configuration, connects the MACSDU data map is corresponding, is sent to SS by air interface then.
The existing application system configuration as shown in Figure 4, unit one and unit two are respectively two local area network (LAN)s, these two local area network (LAN)s adopt the wireless mode access network by BS and SS, are linked into IP network, message protocol stack wherein is as shown in Figure 5.
When up, the Ether frame that PC sends is stamped the VLAN sign through the ether switch, enters SS.SS and BS directly adopt 802.16 encapsulation format to communicate, and do not handle Ether frame, and BS transparent transmission message is given the ether switch of BS side, and the ether switch is handled Ethernet message.When descending, processing procedure and opposite when up.
In existing technology, BS and SS do not handle two layer services, and BS and SS just carry out transparent transmission to Ether frame, and therefore, in the networking of prior art BS and SS, the both need connect an ether switch, and the effect of ether switch is to handle two layers of Ether frame.
Because BS just converges submodule by special services the data in the connection of 802.16 agreements are mapped to Ether frame simply, does not handle Ether frame, therefore this BS equipment is the transparent transmission Ether frame, does not have two layers of disposal ability.
Summary of the invention
