In the time that UE need to access community, first send the RRC connection request message that comprises Target Cell Identifier to base station, Target Cell Identifier is wherein in order to indicate UE will access which community, and therefore base station can determine whether to allow UE access respective cell according to this Target Cell Identifier.
Step 202, determines that the type of described RRC connection request message, described type comprise allow the message that frame is tapped into and forbid the message that frame is tapped into.
If the type of described RRC connection request message is the message that allows frame to be tapped into, perform step 203; If the type of described RRC connection request message is the message of forbidding that frame is tapped into, perform step 205.
The mode of UE access community can be divided mode or continuation mode for frame, wherein a frame point mode refers to that multiple users can use same resource, be that UE can share same resource with other UE in the time of access, continuation mode refers to that a resource can only distribute to user and use, and other users cannot re-use this resource.Therefore, frame point mode, than continuation mode, can be saved carrier resource.Therefore, in this embodiment, the type of RRC connection request message can be divided into and allow the message that is tapped into of frame and forbid two kinds of the message that frame is tapped into, mode that just can be different according to different type selecting after receiving the RRC connection request message that UE sends accesses.
In a preferred embodiment of the present invention, can pass through OAM(Operation, Administration, and Maintenance, operation, management, safeguards) be to allow the message that is tapped into of frame and forbid two kinds of the message that frame is tapped into RRC connection request message arrangement.According to the actual needs of carrier network operation, conventionally the management work of network is divided into 3 large classes: operate (Operation), management (Administration), safeguard (Maintenance), be called for short OAM.Operation mainly completes prediction, planning and the configuration effort that daily network and business are carried out; Safeguard it is mainly the regular job activity that test and the fault management etc. of network and business thereof are carried out.
In the embodiment of the present invention, can set up reason according to RRC the type of RRC connection request message is divided, described RRC sets up reason and can comprise:

17, Call_re-establishment, call re-establishment
18, Terminating_High_Priority_Signalling, called high priority signaling
19, Terminating_Low_Priority_Signalling, called low priority signaling
20, unknown, reason the unknown
Wherein, conversation class can be voice call and visual telephone; Interactive class can be game on line, web page browsing, positioning service; Background class can be for data are downloaded, figure bell is downloaded, mail transmission/reception; Streaming media service can be mobile TV, video request program, traffic monitoring; High priority signaling can be multimedia message; Low priority signaling can be short message, etc.
In the embodiment of the present invention, described RRC sets up reason can be divided into CS class, PS class and short message class.CS business is mainly to comprise some speech businesses, as 64K voice etc., but also comprises some circuit type data services, and the most common is exactly fax; PS business is exactly common data service, also comprises streaming media service etc.Therefore, set up in reason at above-mentioned RRC, caller conversation class, called conversation class and urgent call can be defined as to CS class; Caller Streaming Media class, caller interactive class, caller background class, calling customized class, Called Flow media class, called interactive class and called background class are defined as to PS class; Cell reselection, community switching, registration, attachment removal, caller high priority signaling, caller low priority signaling, call re-establishment, called high priority signaling, called low priority signaling and reason the unknown are defined as to short message class.
In service at existing network, in order to ensure voice user's perception, for the UE that triggers CS business priority access R4 carrier wave in a continuous manner conventionally, because CS business adds CS signaling and independent CS signaling, to access shared local resource identical with Radio Resource, if and CS signaling accesses at R4 carrier wave in a continuous manner, can reduce the reprovision number of times of CS signaling when CS service access, improve the call completing rate of CS business.And for the UE that triggers non-CS business (as short message or PS signaling etc.), for PS traffic signaling, while access at present, preferentially access in a continuous manner R4 carrier wave, can be together with PS business in the time that PS business is set up reprovision to H carrier wave, can remain on R4 carrier wave to short message etc., until signaling discharges always.
Therefore, in the embodiment of the present invention, consider that CS business has relatively high expectations to user awareness, but not CS business requires lower to user awareness, therefore in order to ensure call completing rate, and save carrier resource, and can arrange for the UE that triggers CS class business and adopt continuation mode access, forbid adopting a frame point mode to access, and for the UE that triggers non-CS class business, can allow to adopt a frame point mode to access according to actual conditions.
In a preferred embodiment of the present invention, in the RRC connection request message that described UE sends, can also carry RRC and set up reason, set up reason and can determine the type of described RRC connection request message according to this RRC.
This step 202 specifically can comprise following sub-step:
Sub-step a1, obtains the RRC carrying in described RRC connection request message and sets up reason;
Sub-step a2, if described RRC sets up former because CS class determines that the type of described RRC connection request message is the message of forbidding that frame is tapped into;
Sub-step a3, former in PS class or short message class if described RRC sets up, the type of determining described RRC connection request message is the message that allows frame to be tapped into.
According to foregoing description, described RRC sets up reason can comprise CS class, PS class and short message class, in the embodiment of the present invention in the time that described RRC sets up former because CS class, also be described RRC while setting up former because caller conversation class, called conversation class or urgent call, the type that can determine described RRC connection request message is the message of forbidding that frame is tapped into; In the time that described RRC sets up former because PS class or short message class, also be that described RRC sets up former because caller Streaming Media class, caller interactive class, caller background class, calling customized class, Called Flow media class, called interactive class, called background class, cell reselection, community switching, registration, attachment removal, caller high priority signaling, caller low priority signaling, call re-establishment, called high priority signaling, called low priority signaling or reason when unknown, the type that can determine described RRC connection request message is the message that allows frame to be tapped into.
Step 203, judges whether the load of R4 carrier wave in the Target cell that described Target Cell Identifier is corresponding is greater than default load thresholding.
If the load of R4 carrier wave is greater than default load thresholding in described Target cell, perform step 204; If the load of R4 carrier wave is less than or equal to default load thresholding in described Target cell, perform step 205.
Be the message that allows frame to be tapped into if determine the type of described RRC connection request message in above-mentioned steps 202, whether whether the load that can further judge R4 carrier wave in the Target cell that described Target Cell Identifier is corresponding is greater than default load thresholding, higher to determine the R4 carrier load of Target cell.
In a preferred embodiment of the present invention, the BRU(Basic Resource Unit that in described Target cell, the load of R4 carrier wave can distribute according to R4 carrier wave in Target cell, basic resource unit) number, and in Target cell, the limit code of R4 carrier wave calculates.For example, in BRU number/Target cell that, in Target cell, in the load=Target cell of R4 carrier wave, all R4 carrier waves have distributed all R4 carrier wave limit code summations.Certainly, according to practical experience, those skilled in the art can also calculate the load of R4 carrier wave in Target cell by other means, and the embodiment of the present invention is not limited concrete account form.
After calculating the load of R4 carrier wave in Target cell, result of calculation and default load thresholding can be compared, if be greater than default load thresholding, the load that R4 carrier wave in Target cell can be described is higher, now need to take the access way of saving resource, if be less than or equal to default load thresholding, can illustrate that the load of R4 carrier wave in Target cell is lower, now take conventional access way.Wherein, described load thresholding can be configured by OAM, and for concrete numerical value, the embodiment of the present invention is not limited.
Step 204, adopts frame point mode that described subscriber equipment is accessed to the R4 carrier wave in described Target cell.
Be greater than default load thresholding if judge the load of R4 carrier wave in described Target cell in step 203, the type that described RRC connection request message can be described is the message that allows frame to be tapped into, and now in Target cell, the load of R4 carrier wave is higher, therefore in this kind of situation, can select to adopt frame point mode that the UE of described described transmission RRC connection request message is accessed to the R4 carrier wave in described Target cell, thereby can save R4 carrier resource.
In a preferred embodiment of the present invention, this step 204 can comprise following sub-step:

Owing to now adopting frame point mode that UE is accessed to the R4 carrier wave in described Target cell, therefore after selected target R4 carrier wave, can further judge that in described target R4 carrier wave, whether having attribute is that frame divides and surplus resources is greater than the available resources of described subscriber equipment resource requirement.If exist, can directly these available resources be distributed to described UE; If there is no, the idling-resource in described target R4 carrier wave can be distributed to described UE, and be that frame divides by the attribute-bit of distributed idling-resource, be designated after frame divides, explanation can also allow other UE to use this resource.Wherein, described idling-resource refers to and is also not yet assigned to the resource that any UE uses.
Step 205, adopts continuation mode that described subscriber equipment is accessed to the R4 carrier wave in described Target cell.
If determining the type of described RRC connection request message in step 202 is the message of forbidding that frame is tapped into, can illustrate for the UE that sends this RRC connection request message, need to adopt continuation mode access R4 carrier wave.Be less than or equal to default load thresholding if judge the load of R4 carrier wave in described Target cell in step 203, now also can adopt continuation mode access R4 carrier wave.
In a preferred embodiment of the present invention, this step 205 can comprise following sub-step:
Sub-step c1, selected target R4 carrier wave from described Target cell;
Sub-step c2, distributes to described subscriber equipment by the idling-resource in described target R4 carrier wave, and is continuous by the attribute-bit of distributed idling-resource.
As above-mentioned for the description of step 204, also selected target R4 carrier wave from described Target cell in the following way herein: the surplus resources that obtains each R4 carrier wave in described Target cell; The selected R4 carrier wave that wherein surplus resources is maximum is as target R4 carrier wave.Owing to will adopting continuation mode access R4 carrier wave in this step, and continuation mode illustrates that this UE needs to use separately a resource, therefore, can from described target R4 carrier wave, choose idling-resource and distribute to described subscriber equipment, described idling-resource refers to and is also not yet assigned to the resource that any UE uses.After Resources allocation, can also be continuously by the attribute-bit of distributed idling-resource, to indicate this resource can not reallocate to the UE of other accesses R4 carrier wave.
In the embodiment of the present invention, can in different ways UE be accessed to R4 carrier wave according to the difference of RRC connection request type of message, therefore can save R4 carrier resource, avoid the wasting of resources, thereby can also ensure user awareness.
