Embodiment
The invention discloses a kind of transfer resource distribution method, this method is applied to comprise the access net system of network controller and base station.The design philosophy of this method is: be connected multiple transmission network on network controller and base station node B, comprise: high QoS transmission network and low QoS transmission network, thus QoS transfer resource and two kinds of transfer resources of high QoS transfer resource are hanged down in configuration on network controller and base station.When network controller receives service request, allocation of transmission resources, QoS according to the current business request is that current business is distributed high QoS transfer resource or low QoS transfer resource, and informing base station is corresponding high QoS transfer resource or the low QoS transfer resource of distributing of current business; The base station is that current business is distributed high QoS transfer resource or low QoS transfer resource according to the notice from network controller, finishes whole transfer resource assigning process.
Based on above-mentioned principle, high QoS transfer resource or low QoS transfer resource can be selected to distribute in network controller and base station according to the QoS of current business, therefore can more effectively utilize the transmission resources for transmitting business datum.Described in detail below in conjunction with the processing of accompanying drawing the inventive method.In following examples, network controller and base station refer to the RNC and the base station node B of WCDMA system respectively.
Fig. 1 is the inventive method one preferred embodiment handling process schematic diagram, and as shown in Figure 1, the concrete processing comprises:
After step 101:RNC receives service request, resolve the QoS index of the current business that this service request carries, determine the QoS of current business, according to the height of current business QoS or further combined with the providing capability of current high QoS transfer resource and/or low QoS transfer resource, for current business is distributed high QoS transfer resource or low QoS transfer resource.Here, the basic principle of allocation of transmission resources is: be the high QoS transfer resource of high QoS traffic assignments as far as possible, distribute to low QoS business and will hang down the QoS transfer resource usually.
When system transmissions resource providing capability is comparatively desirable, can only judge the QoS of current business, when judging that current business is that high QoS distributes high QoS transfer resource for it when professional, when judging that current business distributes low QoS transfer resource for it for low QoS when professional, when judging that current business is high QoS business, distribute high QoS transfer resource for it.In addition, also can be used to indicate the transfer resource type default value of high QoS or low QoS transfer resource in advance for more than one business configuration, after receiving service request, judge at first whether this business disposes transfer resource type default value, if have, then the indication by transfer resource type default value distributes high QoS or low QoS transfer resource; Otherwise judge current business QoS, be the high QoS transfer resource of high QoS traffic assignments, be the low QoS transfer resource of low QoS traffic assignments.
But the transfer resource that system can provide can not be kept perfect condition usually always, therefore also will come allocation of transmission resources further combined with the providing capability of current high QoS transfer resource and/or low QoS transfer resource.At this moment, to see subsequent figures 2 for details described for the method for concrete allocation of transmission resources.
Wherein, the part relevant with resource allocation comprises in the RNC: the one or more base-station interface plate of signaling processing plate and control thereof, the transmission network that each base-station interface plate can connect one or more can provide one or more transfer resource, and signaling processing plate comes to be the current business allocation of transmission resources by sending the resource allocation order for the base-station interface plate.In the time will distributing high QoS transfer resource for current business, signaling processing plate is inquired about each base-station interface plate information that high QoS transfer resource can be provided, being defined as current business provides the base-station interface plate of high QoS transfer resource and sends the resource allocation order to this base-station interface plate, is that current business is distributed high QoS transfer resource by this base-station interface plate; In like manner, in the time will hanging down the QoS transfer resource for the current business distribution, signaling processing plate is inquired about each base-station interface plate information that low QoS transfer resource can be provided, being defined as current business provides the base-station interface plate of low QoS transfer resource and sends the resource allocation order to this base-station interface plate, is that current business is distributed low QoS transfer resource by this base-station interface plate.
Transfer resource as herein described promptly refers to the Iub interface transfer resource, and the attachable transmission network of the RNC of Iub interface and base station node comprises: ATM transmission network, phototiming transmit the IP transmission network of (SDH) transmission network, high QoS guarantee, the IP transmission network of low QoS guarantee etc.Usually, the IP transmission network that ATM transmission network wherein, SDH transmission network, high QoS ensure belongs to high QoS transmission network, and low QoS transmission network belongs to the IP transmission network that low QoS ensures; Corresponding, high QoS transfer resource generally includes: the IP transfer resource that ATM transfer resource, SDH transfer resource, high QoS ensure, low QoS transfer resource just refer to the IP transfer resource that low QoS ensures usually.Here, the IP transmission network that high QoS ensures refers to special-purpose IP transmission network or uses the IP transmission network of technology distribution fixed-bandwidths such as multiprotocol label switching (mpls), and the IP transmission network that low QoS ensures refers to common IP transmission network.In addition, the higher business of QoS is that high QoS business generally includes: speech business, video telephone, signaling etc.; The promptly low QoS business of the business that QoS is lower generally includes: WEB web page browsing, information series business, MMS etc.The present invention does not limit for the concrete transmission network of high/low QoS transmission network or high/low QoS transfer resource or the professional representative of high/low QoS or transfer resource or business, but all in protection scope of the present invention.
Step 102:RNC informing base station NodeB is that current business is distributed high QoS transfer resource or low QoS transfer resource.
Because, to send Iub interface transfer resource request for allocation in the prior art after the RNC allocation of transmission resources to base station node B, this Iub interface transfer resource request for allocation is carried information such as the resource identification that distributed, resource size.Therefore, can in this Iub interface transfer resource request for allocation, carry the transfer resource type, thereby can informing base station NodeB be that current business is distributed the still low QoS transfer resource of high QoS transfer resource.
Step 103: base station node B 102 notice set by step is that current business is distributed high QoS transfer resource or low QoS transfer resource.Wherein, compare with RNC, base station node B will distribute the transfer resource of same type to give current business.
Step 104: base station node B is finished and is returned the Iub interface transfer resource after transfer resource distributes and distribute and reply to RNC, this replys information such as the resource identification that carries base station node B and distribute, resource size, transfer resource type, thereby finishes whole transfer resource assigning process.The IP transfer resource that described transfer resource type can indicate ATM transfer resource or SDH transfer resource or high QoS to ensure, or the IP transfer resource of low QoS guarantee etc.
Wherein, the part relevant with resource allocation comprises in the base station node B: the one or more base station Digital Trunk Interface Board of master control borad and control thereof, the transmission network that each base station Digital Trunk Interface Board can connect one or more can provide one or more transfer resource, and master control borad comes to be the current business allocation of transmission resources by sending the resource allocation order for the base station Digital Trunk Interface Board.In the time will distributing high QoS transfer resource for current business, master control borad is inquired about each base station Digital Trunk Interface Board information that high QoS transfer resource can be provided, being defined as current business provides the base station Digital Trunk Interface Board of high QoS transfer resource and sends the resource allocation order to this base station Digital Trunk Interface Board, is that current business is distributed high QoS transfer resource by this base station Digital Trunk Interface Board; In like manner, in the time will hanging down the QoS transfer resource for the current business distribution, master control borad is inquired about each base station Digital Trunk Interface Board information that low QoS transfer resource can be provided, being defined as current business provides the base station Digital Trunk Interface Board of low QoS transfer resource and sends the resource allocation order to this base station Digital Trunk Interface Board, is that current business is distributed low QoS transfer resource by this base station Digital Trunk Interface Board.
When specific implementation, signaling processing plate can be embodied as Wideband Code Division Multiple Access (WCDMA) (WCDMA) signal processing unit (WSPU, WCDMA Signaling Process Unit), the base-station interface plate can be embodied as WCDMARNC base-station interface plate (WBIE, WCDMA RNC Base Station Interface Board), master control borad can be embodied as NodeB master and handles timing unit (NMPT, NodeB Main Processing﹠amp; TimingUnit), the base station Digital Trunk Interface Board can be embodied as NodeB digital relay interface unit (WDTI; NodeBDigital Trunk Interface Unit); the present invention does not limit signaling processing plate, base-station interface plate, master control borad, base station Digital Trunk Board specific implementation and is which kind of processing unit, but all in protection range of the present invention.

Step 202: judge whether current high QoS transfer resource is enough, if then execution in step 205; Otherwise transfer resource distributes failure, finishes to work as pre-treatment.
Here, when judging that current high QoS transfer resource is enough, also further execution in step 203 and step 204:
Whether step 203: judging currently has low QoS business to take high QoS transfer resource, if.Then execution in step 204; Otherwise transfer resource distributes failure, finishes to work as pre-treatment.
Step 204: reduce the professional shared high QoS transfer resource of the low QoS that takies high QoS transfer resource, so that current business can access enough high QoS transfer resources.Such as: can be that speed reduces its shared high QoS transfer resource by the bandwidth that reduces low QoS business.
Step 205: distribute high QoS transfer resource to give current business, finish to work as pre-treatment.
Step 206: judge whether current high QoS transfer resource is enough, if then execution in step 205; Otherwise execution in step 207.
Step 207: judge whether current low QoS transfer resource is enough, if then execution in step 208; Otherwise transfer resource distributes failure, finishes to work as pre-treatment.
Step 208: distribute low QoS transfer resource to give current business, finish to work as pre-treatment.
In above-mentioned steps 201 to the basis of step 208, the inventive method has also proposed another kind of transfer resource distribution method: be used to indicate the transfer resource type default value of high QoS transfer resource or low QoS transfer resource in advance for part or all of business configuration, further comprised before step 201:
Step a: judge whether current business has disposed transfer resource type default value, if, execution in step b then; Otherwise execution in step 201.
Step b: judge the transfer resource type default value of current business, if high QoS transfer resource, then execution in step 202; If low QoS transfer resource, then execution in step 206.
Based on above-mentioned processing method, the invention allows for a kind of system that multiple transfer resource is provided, this system is made up of RNC and base station node.In existing RNC, distribute relevant portion to comprise with transfer resource: the one or more base-station interface plate of signaling processing plate and control thereof; In existing base station node B, distribute relevant portion to comprise with transfer resource: the one or more base station Digital Trunk Interface Board of master control borad and control thereof.The present invention is on the basis of existing RNC and base station node B, transfer resource determination module and interface board determination module are set in signaling processing plate and master control borad respectively, and on each base-station interface plate and each base station Digital Trunk Interface Board, dispose high QoS transfer resource and/or low QoS transfer resource respectively, promptly each base-station interface plate is connected high QoS transmission network and/or low QoS transmission network respectively with each base station Digital Trunk Interface Board.Here, be connected high QoS transmission network and/or low QoS transmission network with the base station Digital Trunk Interface Board about described base-station interface plate, to dispose the implementation method of high QoS transfer resource and/or low QoS transfer resource, can adopt existing techniques in realizing, and non-emphasis of the present invention, so this paper is not described in further detail.
