Embodiment
In the embodiment of the invention, UE will be redirected reference information and send to wireless network control unit, and wireless network control unit is redirected to Target cell according to the redirected reference information from UE that receives with UE.
In addition, wireless network control unit offers UE with all or part of broadcast message of Target cell in the embodiment of the invention, and all or part of broadcast message of the Target cell that UE provides according to wireless network control unit inserts at Target cell.
For making the purpose, technical solutions and advantages of the present invention clearer, below in conjunction with embodiment and accompanying drawing, the present invention is described in more detail.
Fig. 1 is the exemplary process diagram of the method that is redirected in the embodiment of the invention.As shown in Figure 1, this flow process comprises the steps:
Wherein, redirected reference information can comprise: a kind of or its combination in any in the quality measurement information of sub-district, the ability information of UE, the customer attribute information.
Wherein, the quality measurement information of sub-district can comprise that UE is to quality measurement information of each frequency layer sub-district or RAT sub-district etc.
The ability information of UE can comprise the ability information that UE self has, but as information, the frequency information that can insert, the miscellaneous service information of being supported or the specific function information of being supported of connecting system (as single system, dual system or three systems), for example (DT switching), voice continuity switching (VCC switching) etc. are switched in the support region conversion.
Customer attribute information can comprise: the system that the user can insert, user's type (group user/business users/general personal user) and/or default service bearer strategy information such as (preestablish voice service as operator and should preferentially be carried on the global system for mobile communications (GSM), and high-speed data service should be carried on the first-class strategy of long evolving system (LTE)); And these information also can be classified abstract, only be divided into different user gradation information, be that customer attribute information can include only this user gradation information, can use less several bits (bit) to indicate this moment, and for example user gradation information can be: senior, intermediate, rudimentary; Perhaps, also can be: LTE-be senior, 3G-middle rank, modes such as GSM-middle rank.
In the practical application, this redirected reference information can be set up request message or the supplemental messages or the connection setup complete message of the request of connect setting up send by connection.
Wherein, when UE will be redirected reference information and send to wireless network control unit, can be UE according to a kind of or its combination in any in the cell load information that is obtained, the traffic type information that the sub-district is supported, the syntople information of sub-district etc., decision-making send to be redirected reference information to wireless network control unit.Wherein, wireless network control unit can be indicated the situation of this sub-district by common signal channels such as broadcast channel or paging channel, the for example different service types supported of the cell load of this sub-district, this sub-district or the information such as syntople of this sub-district, then UE can be according to the cell load information that obtains from common signal channel, when the offered load of judgement current area is heavier, then can sends and be redirected reference information to wireless network control unit; The traffic type information that UE supports according to the sub-district that obtains is judged when business that current area is supported and the business that self will initiate do not match, and then can send to wireless network control unit and be redirected reference information; UE, then can send to wireless network control unit and be redirected reference information when the UE that judgement is lower can not switch to the sub-district of some adjacency according to the syntople of the sub-district that obtains.
