Step 201:RNC obtains the access request message that UE sends.
In this step, at least comprise in access request message: the mark of current area.
Step 202:RNC obtains the mobile attribute information of UE.
In this step, mobile attribute information at least comprises: current location information and moving direction information.
According to the mobile attribute information of UE and default cell edge indication information, step 203:RNC judges whether UE is in edge, current area.
If so, step 204 is performed.Otherwise, perform step 212.
On the moving direction that step 204:RNC judges UE, whether next community of current area exists available resources.
If so, step 211 is performed.Otherwise perform step 212.
Step 211:RNC sets up next community of current area on the moving direction of UE radio bearer (RadioBear is called for short RB).
In this step, being judged as YES through step 204, namely UE is in edge, current area and on the moving direction of UE, next community of current area exists available resources, then on the moving direction of UE, RB is set up in next community of current area.
Step 212:RNC sets up RB in current area.

Fig. 3 is the flow chart of the user access method of the embodiment of the present invention two.As shown in Figure 3, the method comprises following process.
Step 301:RNC obtains the access request message that UE sends.
In this step, at least comprise in access request message: the mark of the signal quality measured values received signal code power (Received Signal Code Power is called for short RSCP) that the mark of current area, UE are current and target service type.
Step 302:RNC obtains the mobile attribute information of UE.
In this step, mobile attribute information at least comprises: current location information, moving direction information and rate information.In the embodiment of the present invention, the concrete grammar of mobile attribute information that RNC obtains UE is not limited, in actual applications, RNC can be made to get any mode of the mobile attribute information of UE all applicable.Such as, estimate the speed of UE and moving direction by base station (Node B, be called for short NB) and report the cell edge attribute information of frequency deviation, rate information, moving direction information and residing group of paths (Path Group) to RNC.
In the embodiment of the present invention two, only for wherein one preferably execution mode, concrete grammar RNC being obtained to the mobile attribute information of UE is explained.This preferably execution mode adopt localization method to obtain the mobile attribute information of UE.At present, wireless location technology has been widely used in the fields such as emergency relief, auto navigation, intelligent transportation, Generation Mobile Telecommunication System and/or 3G (Third Generation) Moblie (2G/3G) network all realize positioning function, third generation partner program (3rd Generation Partnership Project is called for short 3GPP) agreement also can realize the function of wireless location.The maturation of user positioning technology and broad practice, carry out the feasibility of UE access operation for utilizing location technology and practicality lays a solid foundation.Further, because positioning action and UE access operation complete by RNC, therefore RNC can realize utilizing location technology to complete the access operation of UE neatly, has compatible and degree of realization preferably.Particularly, this preferably execution mode can comprise following process.
The first step, RNC obtain UE at first positional information, current location information and described UE from the time moving to current location in first position.
Particularly, in this preferably execution mode, arranging locating periodically timer in the rnc, is this locating periodically set timer timing length.The size of the timing length of locating periodically timer can be configured by RNC, and its size is less than the time that train surmounts a community.Whenever the locating periodically timer expiry arranged, RNC adopts localization method to obtain the positional information of UE in locating periodically moment of time-out of timer, thus RNC can obtain repeatedly the positional information of UE constant duration, and RNC stores above-mentioned positional information.When certain locating periodically timer expiry, using the positional information of the UE of this locating periodically moment of time-out of timer as current location information, the positional information of the UE in above one-time positioning cycle timer time-out moment as in first positional information, and using the timing length of locating periodically timer as UE from the time moving to current location in first position.Such as, the timing length of locating periodically timer is T
location.After locating periodically timer starts, such as, at moment t
1, locating periodically timer expiry, adopt localization method to position UE, obtaining this UE positional information is now
now locating periodically timer starts again, at moment t
2time, locating periodically timer expiry, again adopt localization method to position UE, obtaining this UE positional information is now
of this sort, the repeated multiple times startup of locating periodically timer, positioning UE position at that time after each time-out.
In this better embodiment, do not limit concrete localization method, every localization method that can obtain the position of UE in mobile network is all applicable.Such as, RNC can adopt the direction angle of arrival (Angle of Arrive, be called for short AOA) location technology, the time of advent (Time Of Arrival, be called for short TOA) location technology, the time of advent poor (Tiime Difference of Arrival, be called for short TDOA) location technology, radio-frequency (RF) identification (RadioFrequency Identification, be called for short RFID) location technology, utilize received signal strength (Received SignalStrength Indication, be called for short RSSI) location technology and global positioning system (Global PosiftoningSystem, be called for short GPS) the multiple location technology such as location technology, obtain the positional information of UE.
Second step, RNC according to the current location of UE, UE at first position and default moving direction decision threshold, judge the moving direction of UE.
Particularly, RNC presets moving direction decision threshold, and this moving direction decision threshold is a default length, and the numerical value of this moving direction decision threshold is greater than zero.If the current location of UE be more than or equal to default moving direction decision threshold in the difference of first position, then RNC judges that the moving direction of UE is up direction, thus RNC acquisition UE moving direction information be up direction.If UE is more than or equal to default moving direction decision threshold in the difference of first position and current location, then RNC judges that the moving direction of UE is down direction, thus the moving direction information that RNC obtains UE is down direction.
For the scene shown in Fig. 1, using the travel direction of high ferro as X-coordinate, with X-coordinate axle positive direction for high ferro up direction, X-coordinate axle negative direction is high ferro down direction, and the starting point of high ferro circuit is initial point (0,0), the terminal of high ferro circuit is in X-coordinate axle positive direction, the up-downlink direction of high ferro private network adjacent area is based on the unified configuration of above-mentioned definition, and up direction is the direction from initial point toward the movement of X-coordinate axle positive direction, and down direction is the direction of X-coordinate axle positive direction toward initial point movement.Arranging moving direction decision threshold is X
location, X
location> 0, when
uE moving direction is up direction, when
the moving direction of UE is down direction.
3rd step, RNC according to the current location of UE, at first position and UE from the time moving to current location in first position, calculate the speed of UE.
Particularly, RNC with the absolute value of current location and difference in first position divided by UE from the time moving to current location in first position, its result of calculation is the speed of UE, thus RNC obtains the rate information of UE.With
represent UE in first position, with
represent the current location of UE, with T
locationrepresent that UE is from the time moving to current location in first position, then RNC is according to formula
the speed v of UE can be calculated
current.
The execution sequence of above-mentioned second step and the 3rd step can exchange, or second step and the 3rd step perform simultaneously.
Step 303:RNC judges whether the speed of UE is more than or equal to default rate threshold.
If so, step 304 is performed.Otherwise, perform step 312.
Particularly, arranging rate threshold is v
location, v
location> 0, works as v
current>=v
locationtime, the present speed state justify of UE is at a high speed, performs step 304.For other situation, the speed state judgement of UE is the unknown state of acquiescence.The speed state information keeping this to adjudicate before upper once timer expiry after each judgement.
According to the mobile attribute information of UE and default cell edge indication information, step 304:RNC judges whether UE is in edge, current area.
If so, step 305 is performed.Otherwise, perform step 312.
Particularly, pre-set the edge cover area of each high-speed rail cell in the rnc, comprise ascending edge overlay area and descending edge cover area.See Fig. 1, in the scene shown in Fig. 1, for high ferro private network community 2, pre-set the ascending edge overlay area of this high ferro private network community 2 and descending edge cover area in the rnc.Particularly, the Ω in Fig. 1

In embodiments of the present invention, further, the mark that can also " whether can carry out RB for the high ferro neighbor cell configuration of current area and preferentially set up access ", this flag bit is preset and is defaulted as no (FALSE).If UE is positioned at the edge cover area on the UE moving direction of current area, so just the flag bit of the next high ferro adjacent area on this moving direction " whether can carry out RB and preferentially set up access " is set to be (TRUE).Otherwise, if UE is not positioned at the edge cover area on the UE moving direction of current area, or cannot judge whether UE is positioned at the edge cover area on the UE moving direction of current area, the flag bit of the next high ferro adjacent area then on this moving direction " whether can carry out RB and preferentially set up access " does not change, and is still no.In follow-up flow process, when needing the judged result of the edge cover area whether be positioned on the UE moving direction of current area for UE according to this step to process, the flag bit of the next high ferro adjacent area on the UE moving direction of direct inquiry current area " whether can carry out RB and preferentially set up access ", if this flag is yes, then can know that the judged result of this step is the edge cover area that UE is positioned on the UE moving direction of current area.
Step 305:RNC judges whether the current RSCP of UE is less than or equal to default RSCP thresholding.
If so, step 306 is performed.Otherwise, perform step 312.
On the moving direction that step 306:RNC judges UE, whether next community of current area exists available resources.
If so, step 311 is performed.Otherwise perform step 312.
Particularly, within step 306, first, RNC is according to the mark of the target service type in access request message, and on the moving direction judging UE, whether next community of current area exists the resource of available target service type.If RNC judges to exist the resource of available target service type, then on the moving direction of UE there are available resources in next community of current area, and continue to perform step 311.
Then, if RNC judges not exist the resource of available target service type, then RNC continue to judge UE moving direction on next community of current area whether there is the resource of other available type of service.If RNC judges to exist the resource of other available type of service, then on the moving direction of UE there are available resources in next community of current area, and continue to perform step 311.
Particularly, above-mentioned target service type can be R4 type of service, and correspondingly, other type of service can be H type of service.Or above-mentioned target service type can be H type of service, correspondingly, other type of service can be R4 type of service.
Step 311:RNC sets up next community of current area on the moving direction of UE radio bearer (Radio Bear is called for short RB).
In this step, particularly, if RNC judges the resource that there is available target service type in step 306, then on the moving direction of UE, next community of current area RB is set up with the carrier wave of target service type in step 311.If RNC judges not exist the resource of available target service type but there is the resource of other available type of service in step 306, then on the moving direction of UE, next community of current area set up RB with the carrier wave of other type of service in step 311.
Step 312:RNC sets up RB in current area.
In this step, particularly, RNC sets up RB with the carrier wave of target service type in current area.
Further, after step 311 or step 312, one time service access flow process completes.No matter whether this UE accesses successfully in Target cell, the flag bit all whether UE produced in this flow process being in the information of cell edge and " whether can carry out RB and preferentially set up access " of all high ferro adjacent areas empties.Whether UE is in the information default of cell edge for unknown, and the flag bit of all high ferro adjacent areas " whether can carry out RB and preferentially set up access " is defaulted as no.Cut-in method provided by the invention does not affect by business number, if this business is the 1st business of this UE, then, after the 1st business is set up, the Serving cell of this UE upgrades, and the 2nd business of UE still can realize according to this method.For voice and packet data concurrent service, such as, UE has built the speech business that the 1st belongs to R4 business, this UE follow-up asks again to set up a H business, then for the request of setting up this H business, according to the cut-in method of the embodiment of the present invention, if meet the Rule of judgment in above-mentioned step, then this H business can be based upon the next high ferro adjacent area of the current service cell on UE moving direction.
In the embodiment of the present invention two, after UE initiates access request, mobile attribute information according to UE judges, if this UE is in edge, current area and on UE moving direction, next community of current area exists available resources, then on UE moving direction, RB is set up in next community of current area, thus avoid the access failure that high ferro user causes because movement velocity is too fast, improve the success rate that high ferro user accesses community.Further, RNC can obtain the positional information of UE by multiple localization method, according to the information such as speed, moving direction of the positional information calculation UE of UE.Because above-mentioned positioning action and UE access operation complete by RNC, therefore RNC can be known easily and utilize the parameter obtained by positioning action, realize neatly utilizing location technology to complete the access operation of UE, not only increase the success rate that high ferro user accesses community, and it is easy and simple to handle, easy to implement.
Fig. 4 is the structural representation of the RNC of the embodiment of the present invention three.As shown in Figure 4, this RNC at least comprises: message reception units 41, mobile attribute information acquiring unit 42, judging unit 43 and connection establishment unit 44.
