Description
Technical field
The present invention relates to micro-wave access to global intercommunication (WiMAX) technical field, be meant the method for a kind of base station (BS) selection access service network gateway (ASN-GW, Access Service Network GateWay) especially.
Background technology
Along with the extensive use of the flourish and wireless network of internet service, the WiMAX 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.
Figure 1 shows that WiMAX network architecture system schematic diagram.WiMAX network architecture system generally includes access service network (ASN, Access Service Network) and connectivity serving network (CSN, Connectivity Service Network) and subscriber terminal equipment.This user terminal can be mobile subscriber equipment (MSS), also can be subscriber equipment (SS).
ASN is the network function set that the wireless access service is provided for subscriber terminal equipment, has comprised BS and ASN-GW network element among the ASN.Wherein, BS is mainly used in provides BS to be connected with the L2 of MSS/SS; RRM; Measure and power control; The compression of the data of eating dishes without rice or wine and encryption etc.The authentication that ASN-GW is mainly used in to MSS/SS provides client functionality; The network of support network services provider (NSP) is found and selection function; For MSS/SS provides relaying (Relay) function of L3 information, as IP address assignment; RRM etc.ASN can also possess in following non-essential function: the ASN and switch except possessing above-mentioned essential function; MSS/SS paging and location management; Tunnel management between the ASN-CSN, it is equivalent to the external agent (FA) in the mobile IP technology; Vision location registration etc.
CSN is used to the WiMAX terminal that IP is provided Connection Service, and it is mainly used in the IP address assignment of MSS/SS; Internet inserts; Authentication agency or server (AAA proxy orServer) function; Authorization control based on the user; ASN is equivalent to the home agent (HA) in the mobile IP technology to the tunnel management of CSN; WiMAX user's charging and the clearing between the operator; Tunnel management under the roaming condition between the CSN; Switching between the ASN; Various WiMAX services are as location-based business, multi-medium multi-packet broadcasting and broadcasting service, IP Multimedia System business etc.
MSS/SS inserts the BS that uses and is called serving BS broadcasts (Serving BS).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 (Serving ASN-GW).For example ASN-GW1 is exactly the service ASN-GW of BS1 and BS2 among Fig. 1.Exist the ASN-GW of Interface R3 to be called as anchor ASN-GW (Anchor ASN-GW) with the interior HA of CSN in the ASN.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.
Referring to Fig. 1, from data surface, the downlink grouping traffic datagram that sends to MSS/SS, is sent among the ASN by the Interface R3 between the anchor ASN-GW HA and the ASN from the HA of CSN.Afterwards, the Interface R4 of this downlink grouping traffic datagram process ASN inside is sent to the service ASN-GW of MSS/SS, is sent to serving BS broadcasts through the R6 interface, and finally sends on the MSS/SS.The upstream packet business datum then is delivered to the CSN along opposite path from MSS/SS and reaches end subscriber.As mentioned above, the data path (Data Path) of corresponding uplink and downlink is arranged all for each Business Stream of each MSS/SS in ASN inside, these data paths are set up along with the foundation of each Business Stream; Discharge along with the termination of Business Stream.
Can be that multi-to-multi connects between BS and the ASN-GW, in Fig. 1, ASN-GW1 can connect BS1 and BS2 simultaneously, and BS1 can be connected on ASN-GW1 and the ASN-GW2 simultaneously.
But the appendix F chapters and sections in existing 050915_NWG_STAGE2 agreement, the address of only mentioning ASN-GW is supposed and is configured among the BS, only considered that BS connects the scene of single ASN-GW, do not considered how BS selects ASN-GW under the multi-to-multi networking mode of BS and ASN-GW.Therefore, under the multi-to-multi networking mode of BS and ASN-GW, how BS selects ASN-GW is a problem anxious to be solved.
