Example in Fig. 1 and other network configuration that is used for interactional structure can be configured to for the structure of supporting to disperse (half is flat), (for example allow Access Network, 110 and 120) with the separating of IP Connection Service, and (for example allow different Access Networks, 110 and 120) interact by common core net (for example, 130).In example in Fig. 1, common book keeping operation (Billing) and consumer's management (care) can be implemented, think WiMAX utilization rate in ASN 120 and the EV-DO utilization rate in 3GPP2 network 110, and unified authentication, authentication and the operation of keeping accounts provide a bill.AAA can be processed by core net platform 130.Wireless terminal or mobile radio station, mobile phone or have the computer 101 of wireless network access card 102 for example, Access Network 110 and 120 wirelessly, take by core net 140 for phone and several data business (for example, multimedia and TV broadcasting) or one acquisition wireless service.Based on technology and the network design described in the application, wireless terminal and mobile radio station can monitor that the load capacity of base station is (for example to carry out different Access Networks, the network 110 and 120 of two isomeries in Fig. 1, or two different Access Networks runing based on identical technology but by different operators) on load balance.In addition, wireless terminal or mobile radio station can also monitor that the load capacity of the base station in identical Access Network (for example, 110 and 120) is to carry out mobile switching the from a base station to another base station based on load balance.
Common core network 130 can be configured to enable operation person can safeguard an IP kernel 136, for example, and AAA, MIP HA, Dynamic Host Configuration Protocol server, the element of regulation and management different access technologies (for example, the WiMAX in Fig. 1 120 and EV-DO 110).Common core network 130 can also be configured to allow the user to pass through WiMAX 120 or EV-DO110, perhaps comes all services and application in core network access 130 by network 110 and 120.Similarly, core net 130 is public for different Access Networks 110 and 120, and the bridge between networking 140 and Access Network 110 and 120 is provided.
Example in Fig. 1 can be used in to provide and passes through to use bimodulus MS in roaming between different Access Network 110 and 120 with by using the scheme based on transfer technology between netting, so that seamless conversation to be provided when safeguarding the IP conversation continuity.Two typical Access Networks 110 shown in Figure 1 and 120 are to provide the access of isomery: the network 120 of (1) WiMAX BS, be used for providing ASN gateway via core net 130 to be connected to the WiMAX airlink of MS and connection to core net 130, and the network 110 of (2) EV-DO BS, be used to form AN, it also provides EV-DO airlink by the PDSN 140 to MS in core net 130 to the connection of core net 130.Conversation continuity and mobility can act on behalf of by foreign side (FA) and we agency (HA) is supported.

Can realize that the load balance that MS initiates provides general load balance to solve scheme with the inserting technology networks to isomery in the system 100 of Fig. 1 and other heterogeneous access networks.The load balance that MS initiates can also be used for the load balance of inner inserting technology networks.The load balance that the particular instance of Fig. 1 uses MS to initiate is to provide the load balance between the network 120 and 110 that WiMAX and EV-DO be co-located.
In Fig. 1, WiMAX 120 and EV-DO 110 are configured in different frequency bands.Its available capability (AC) information is periodically broadcasted in each WiMAX and EV-DO base station.Broadcast independently AC information by each WiMAX and EV-DO base station via the available capability signaling message.WiMAX and EV-DO dual-mode terminal are configured to access WiMAX and EV-DO airlink, and monitor the available capability information broadcast from many BS of many BS of WiMAX network 120 and EV-DO network 110.Dual-mode terminal can calculate network load information in other system information from available capability message and pre-configured parameter or broadcast.Each dual-mode terminal is initiated to initiate in net between technology or net technology based on the load information that receives in one or more received AC message and is switched (switch-over).
The specific embodiment of the load balance that this MS of the AC message that monitors based on MS initiates can be used in and obtains one or more advantages.For example, this MS load balance of initiating can be used in the general solution of the load balance between the technology Access Network of technology that isomery is provided and isomery.Again for example, the load balance of this MS initiation can be used in the decoupling of supporting different Access Networks.Again for example, the load balance that this MS initiates can be used in the complexity that reduces the network architecture, and is used for being integrated into relatively easily following pure flat network architectures (pure flat network).As another example, because initiate load balance in the MS side, the load balance that therefore this MS initiates can be used in provides load balance (switching) step of partly transferring the same as or similar to standard.
In an embodiment of the load balance that MS initiates, available capability message can be used in based in the different Access Network of the information reporting in AC message (for example, WiMAX network 120 in Fig. 1 and EV-DO network 110) load, and trigger the switching of Access Network.MS is switched to another Access Network to be equilibrated at balance airlink load between a plurality of Access Networks from an Access Network.
The broadcasting of available capability message can be minimized to reduce the requirement of airlink power, can make based on the frequency of AC message the AC message optimization that is positioned at the upper strata.The broadcast cycle of available capability message (for example) can be configurable system parameters, and can be configured manually to optional value.Can also loading condition Network Based dynamically control broadcast cycle by BS.If one or more loading condition accesses have defined the system of restriction, accelerate MS triggering load balance thereby can reduce broadcast cycle.
When using available capability message, can use the several parameters in available capability message.For wireless (OTA) transmission, can be with the big or small optimization of AC message.The specific embodiment of available capability can be defined as the several parameters that comprise following parameter:
A. available capability (AC) type: be used for expression AC and be for current time or be used for potential cycle (potential period) (frame) from current time.
B. available capability percentage: with regard to untapped radio link power, it can be the AC on down link (DL) or up link (UL).For example,
I.DL AC: 3 or 4 bits that represent available DL percentage power;
Ii.UL AC: 3 or 4 bits that represent available UL percentage power;
C. switching threshold: for the load balance operation arranges it.
I. at first, can (switch-in) CINR (carrier-to-interference plus noise ratio)/the modulation rate threshold value setting be configurable parameter with switching.If be used for MS that the CINR of that network measures higher than this AC message value, this MS can be switched into this network.
Ii. secondly, can with switching (switch-out) CINR/ modulation rate threshold value setting is configurable parameter.If be used for MS that the CINR of that network measures lower than this AC message value, this MS can be switched and this network.
The load balance embodiment that two MS initiate is below described as an example.In one embodiment, monotroded connecing (SC) load balance utilizes MS to monitor that simultaneously a plurality of airlinks in interaction region also improve to reduce the incubation period of transferring the success rate of transferring.In this scheme, MS only connects from the airlink of the best a L3 connection that is established to core network.In another embodiment that is called as multi-link (MC) load balance, MS monitors and obtains a plurality of L2 connections of airlink simultaneously, and MS connects from a plurality of L3 that all available airlinks are established to core network.
As particular instance, can realize in the following manner the SC load balance.Each MS has the independently airlink module such as WiMAX and EV-DO module.Each MS is configured to observe existing MIPv4 and MIPv6 agreement.Each MS has unique NAI and has been assigned unique HoA from HA.At the HA place, the address (CoA) of binding MS and the management of host address (HoA).In operation, for example, the MS that is connected to an Access Network moves to many network coverages, and wherein, MS is keeping monitoring new available airlink in existing the connection.MS checks the available capability message that connects from a plurality of airlinks.If MS detects the load of current network and has arrived given threshold value or arrived and switch threshold value, (if in the neighbor cell of current techniques network or other technical network, some available capability being arranged) MS transfers via standard L2 and is initiated to the switch step of other network, and the switching of having satisfied neighbor cell or other network enters requirement.MS keeps the IP conversation continuity by MIP-HA.MS and MIP-HA keep the IP layer seamless to using.
The available capability control algolithm that is used for the load balance that MS initiates can rest on different network nodes, for example, is used for the BSC of EV-DO network and is used for the BS of WiMAX.The available capability control algolithm can (for example) use the algorithm of existing CDMA load controlling mechanism or letter to determine loading condition.In operation, the available capability control algolithm on each network is controlled offered load by adjusting (1) available capability percentage and (2) switching threshold.
Therefore, initiate by MS the load balance that MS initiates, to be reduced at the realization of load balance in heterogeneous access or isomorphism Access Network.Each BS all broadcasts its control information that is written into and changes, and MS automatically switches into network or from network according to available capability information and the requirement of using QoS and switch, with balance network load.BS controls its load by the dish number of adjusting in AC message.
