It is not meant to that the two must coordinate implementation, in fact, when first network and the second network side are performed separately, also solves point
Not in the problems of first network side, the second network side, when simply the two is used in combination, superior technique effect can be obtained
Fruit.
Under the network scenarios shown in Fig. 3, UE is located at the base station of LTE（eNB）Scope is collectively covered with the AP1 of WLAN
Under.UE communicates with eNB, and establishes 2 carryings with eNB, respectively transmission services 1 and business 2.Follow-up UE find AP1 it
Afterwards, based on the strategy in ANDSF, establish and associate with AP1, and business 1 is switched to AP1 from eNB.In this way, UE at the same time with eNB and
AP1 keeps connection, and business 1 is transmitted by AP1, and business 2 is transmitted by eNB.
The identification informations of UE in a wlan are media access controls（Medium Access Control, MAC）Address, also
It can be the association identification in WALN.
Under connection status, identification informations of the UE in LTE is Cell Radio Network Temporary Identifier/Identity, Cell-RNTI（Cell Radio
Network Temporary Identify, CRNTI）, under idle condition, identification informations of the UE in LTE is Non-Access Stratum
（Non-Access Stratum, NAS）Mark, such as international mobile subscriber identity（International Mobile
Subscriber Identification Number, IMSI）Deng.
If follow-up AP1 has found the demand for having migration UE to LTE network.Such as AP1 occur overload either disturb it is excessive or
Know that the communication quality of UE is poor, therefore make the judgement of migration UE to other AP.But UE is in the coverage of AP2 at this time
Interior A Wei Ge, AP1 are by UE to AP2 beacons（beacon）After channel measures, learn that AP2 is also at overload or interference too
Greatly, the service of WLAN can be around provided without suitable AP.Or UE is in B Wei Ge, the coverage of AP2 is not at
（Without other alternative AP）, at this time AP1 determine in WALN that load balancing can not be carried out to UE, will by AP-eNB signaling interfaces to
ENB transmission load balancings are asked.
The first processing procedure is as shown in figure 4, specifically include following operation：
Step 300, AP1 obtain its identification information in LTE by data frame from UE.
Since UE still has service bearer in LTE, then the identification information that UE is sent to AP1 can be in LTE
The mark of CRNTI or NAS.
Step 310, AP1 establish identification informations of the UE in WLAN and LTE and correspond to relation, and the correspondence is sent to
eNB。
For example, identification informations of the UE in WLAN and LTE corresponds to relation i.e., the MAC Address and UE of UE1 is in LTE
Identification information corresponds to relation
Step 320, AP1 are asked to eNB transmission load balancings, and the MAC Address of UE is carried in the load balancing requests.
After step 330, eNB obtain the load balancing requests, believed by mark of the MAC Address and UE of UE in LTE
Correspondence is ceased, finds UE, and in the manner described above（One）Or mode（Two）Follow-up load balance process is carried out to the UE.
Second of processing procedure is as shown in figure 5, specifically include following operation：
Step 400, AP1 obtain its identification information in LTE by data frame from UE.
Since UE still has service bearer in LTE, then the identification information that UE is sent to AP1 can be in LTE
The mark of CRNTI or NAS.
Step 410, AP1 are asked to eNB transmission load balancings, and marks of the UE1 in LTE is carried in the load balancing requests
Information.
After step 420, eNB obtain the load balancing requests, by identification informations of the UE in LTE, UE is found, and press
According to aforesaid way（One）Or mode（Two）Follow-up load balance process is carried out to the UE.
For the processing procedure shown in Fig. 5, optionally, between step 400 and step 410, AP1 can also establish UE and exist
The correspondence of identification information in WLAN and LET, and the correspondence is sent to eNB.
Specifically, if eNB has found that UE has connection in the lte networks, it can use dedicated signaling notice UE will
The Business Stream for being carried on WLAN is switched back under the eNB, by LTE come bearer service.Or business of the UE in WLAN is discharged, or
Person notifies UE to be carried on the service switching of WLAN before to the adjacent eNB of the eNB.
Under the network scenarios shown in Fig. 3, UE is located at the collectively covering under scope of eNB and AP1.UE communicates with eNB,
And 1 carrying is established with eNB, it is used for transmission business 1.After follow-up UE has found AP1, establish and associate with AP1, and by business 1
AP1 is switched to from eNB.In this way, UE only keeps connecting with AP1.
If follow-up AP1 has found the demand for having migration UE to LTE.Such as AP1 occurs overload and either disturbs excessive or know
The communication quality of UE is poor, therefore makes the judgement of migration UE to other AP.But UE is in A in the coverage of AP2 at this time
After Wei Ge, AP1 measure AP2beacon channels by UE, learn that AP2 is also at overload or interference is too big, and surrounding
There is no the service that suitable AP can provide WLAN.Or UE is in B Wei Ge, the coverage of AP2 is not at（It is alternative without other
AP）, at this time AP1 determine in WALN that load balancing can not be carried out to UE, it is equal load to eNB will to be sent by AP-eNB signaling interfaces
Weighing apparatus request.
Its processing procedure may refer to Fig. 4 and Fig. 5.Difference is：
Since UE does not have service bearer in LTE, then the identification information that UE is sent to AP1 is the mark of NAS.
ENB has found that UE there is no connection, first can send paging message to UE, allow UE to enter connected state in the lte networks
UE is notified to switch back to the Business Stream for being carried on WLAN under the eNB by dedicated signaling afterwards, by LTE come bearer service.Or
Person discharges business of the UE in WLAN, or notice UE will be carried on the service switching of WLAN before to the adjacent eNB of the eNB.
It should be pointed out that although the embodiment of the present invention is using WLAN as first network, LTE is to be said exemplified by the second network
It is bright.But it is not limited only to this application scenarios.As long as some network in heterogeneous network determines not loaded in present networks
