Description
Technical field
The present invention relates to network communications technology field, relate in particular to a kind of processing method of switching and cancellating for wireless access network.
Background technology
Along with the extensive use of the flourish and wireless network of internet service, WiMAX (micro-wave access to global intercommunication) system has obtained a large amount of application and concern with its good wireless access characteristic.How the WiMAX system is applied to the mobile subscriber, better provides Packet Service between network and the mobile subscriber to transmit or the function of route becomes the new focus of industry research.
Be example with WiMAX network architecture system shown in Figure 1 below, the function of each network element in the WiMAX wireless access system that adopts wireless access technology be described:
In Fig. 1, described WiMAX wireless access system comprises MSS/SS (mobile subscriber station), ASN (access service network) and CSN (connectivity serving network).
Wherein, described MSS is a mobile subscriber equipment, and SS is a subscriber equipment, and the user uses this devices accessing WiMAX network.
Wherein, described ASN comprises BS (base station) and ASN-GW (access service network gateway) etc., is used to the WiMAX terminal equipment that the network function set of wireless access service is provided.As, functions such as the compression of being connected of BS and MSS/SS, RRM, measurement and power control, the data of eating dishes without rice or wine and encryption are provided based on described BS; Based on described ASN-GW, for MSS/SS authentication function provides proxy (agency) function, supports the network of NSP to find and select, provide for MSS/SS the functions such as Relay function (as IP address assignment), RRM of L3 information.
Wherein, described CSN is used to the WiMAX terminal that IP is provided Connection Service.As, for MSS/SS distributing IP address, provide Internet to insert, AAA proxy or server are provided, authorization control based on the user is provided, ASN be provided the tunnel to CSN, be equivalent to the tunnel between the CSN, the switching between the different ASN under the HA (home agent) in the mobile IP technology, the charging that WiMAX user is provided and the clearing between the operator, the roaming condition, and various WiMAX service (as location-based business, multi-medium multi-packet broadcasting and broadcasting service, IP Multimedia System business) etc.
Wherein, the BS that MSS/SS insert to use is called serving BS broadcasts, for the MSS/SS that uses certain serving BS broadcasts to insert, and the ASN-GW of R6 interface is arranged between this BS, be called service ASN-GW, for example ASN-GW1 just is to use the service ASN-GW of the MSS/SS that BS1 or BS2 insert among Fig. 1.
Provide the ASN-GW of the Interface R3 between the R3 of the HA from ASN to CSN to be called anchor ASN-GW, the anchor ASN-GW among Fig. 1 is a logic entity, and it can be present in the identical or different physical entity with the logic entities such as ASN-GW1, ASN-GW2 among Fig. 1.
When anchor ASN-GW was present in the identical physical entity with service ASN-GW, interface between the two belonged to the device interior interface, not necessarily will use the standard Interface R4.
The process of transfer of data between each network element is still described in conjunction with Fig. 1 below:
The grouping busihess data of descending MSS/SS newspaper, is sent among the ASN by the Interface R3 between the anchor ASN-GW HA and the ASN from the HA of CSN.After the grouping busihess data newspaper of descending MSS/SS enters ASN, be sent to the service ASN-GW of MSS/SS through the Interface R4 of ASN inside, and send on the MSS/SS through the R6 interface between inner ASN-GW of ASN and the BS and the R1 interface between BS and the MSS/SS data MSS/SS by service ASN-GW.
Upstream data then is delivered to the CSN along opposite path from MSS/SS and reaches end subscriber.As mentioned above, the data path that corresponding uplink and downlink is all arranged for each Business Stream of each MSS/SS in the interface of ASN inside, these all can be set up according to the qos requirement of each Business Stream and the employing mode of data path when each Business Stream is set up.When this service ending, when just Business Stream is ended, just need to discharge corresponding data path.
When MSS/SS may move to the area of coverage of another BS from the area of coverage of a BS in moving process, and serving BS broadcasts and target BS be when belonging to same ASN-GW, and the switching of generation is called R6 interface mobility and switches.As shown in Figure 2, before the switching of R6 interface took place, MSS/SS used the BS2 access network; The switching of R6 interface for after taking place in Fig. 3, and MSS/SS uses the BS1 access network.
When MSS/SS may move to the area of coverage of another BS from the area of coverage of a BS in moving process, and serving BS broadcasts and target BS be when belonging to different ASN-GW, and the switching of generation is called the Interface R4 mobility and switches.As shown in Figure 2, as shown in Figure 4, MSS/SS used the BS3 access network after Interface R4 switched before Interface R4 switched, and can see, MSS/SS carries out data by the Interface R4 data path of setting up between new service ASN-GW and the anchor ASN-GW and transmits.
In handoff process, usually owing to some reasons can be cancelled handover operation at any time, prior art is handled the cancellation operating process, sends the cancellation indication usually to serving BS broadcasts, indication serving BS broadcasts cancellation handover operation.
Above-mentioned technical disadvantages is that the cancellation indication of transmission has only defined the handover cancelling of eating dishes without rice or wine, and does not stipulate the cancellation behavior that access service network is concrete, can cause related resource not to be released like this or postpone discharging, and causes waste of network resources.
