Abstract
The invention discloses a configuration to share the transmission bandwidth on the cascade open base station. The method is: for each cascade antenna, according to the actual needs of the users, the RNC dynamically allocates the recourses to the user. When the RNC detects the access of the user, it will judge whether the currently available transmission bandwidth satisfy the actual needs of users' Iub consumption of transmission bandwidth. If met, it will allocate the Iub transmission bandwidth they really need and allow access, which will reduce the waste on the Iub transmission bandwidth; otherwise, no access is allowed. When the RNC detects that someone releases the connection, it will release the allocated bandwidth for the user, which will increase the Iub transmission bandwidth of the actual needs of users. The method of the present invention provides the cascade between the upper and lower levels with maximize AAL2PATH bandwidth sharing, saves the transmission bandwidth, improves the Iub transmission bandwidth utilization efficiency and reducs operating costs of the network operators.
Description
Technical field
The present invention relates to the resource distribution technology, be meant a kind of method for shared configuring cascade base-station transmission band width especially.
Background technology
Referring to shown in Figure 1, the networking that networking permanent virtual connection (PVC) is applied to radio network controller (RNC) and upper-level BTS (NodeB), RNC and the NodeB of subordinate, upper-level BTS (NodeB) and subordinate base station is connected.Wherein, higher level NodeB level is associated with the NodeB of subordinate, and higher level NodeB is by configuration networking PVC, and each the PVC configuration exchange route for the NodeB of subordinate is downstream site switching asynchronous transfer mode (ATM) cell.
Have a plurality of PVC on the NodeB of the subordinate Iub interface, the corresponding relation of higher level NodeB networking PVC and the NodeB of subordinate Iub interface PVC is: if networking PVC is configured to carry out the VC exchange, the corresponding PVC of networking PVC is for this PVC provides the exchange route.
Referring to shown in Figure 2, NodeB supports cascade, and wherein, NodeB1 is first order NodeB, and NodeB2 and NodeB3 are second level NodeB, and NodeB4 is third level NodeB.The NodeB of the first order directly links to each other with RNC, and second level NodeB communicates by letter with RNC by first order NodeB, and third level NodeB communicates by letter with RNC with third level NodeB by second level NodeB, so analogizes.
In order to make next stage NodeB and RNC realize communicating by letter, NodeB at the corresponding levels is necessary for its configuration networking PVC, and as shown in Figure 3, if realize that RNC communicates by letter with NodeB1, RNC and NodeB1 need configurating PVC 1 as termination PVC.If realize that RNC communicates by letter with NodeB3, RNC needs configurating PVC 2 as termination PVC, and NodeB3 needs configurating PVC 3 as termination PVC, and configuration networking PVC finishes the exchange of PVC2 to PVC3 on NodeB1 simultaneously.As realizing that RNC communicates by letter with NodeB4, RNC needs configurating PVC 4 as termination PVC, NodeB4 needs configurating PVC 6 as termination PVC, and configuration networking PVC finishes the exchange of PVC4 to PVC5 on NodeB1 simultaneously, and the last configuration of NodeB3 networking PVC finishes the exchange of PVC5 to PVC6.
For convenience, the NodeB that below will dispose networking PVC is called cascade NodeB, and the NodeB of configuration termination PVC is called termination NodeB.
In the prior art, adopt ATM Adaptation Layer type 2 path (AAL2Path) bandwidth of fixed allocation mode at the NodeB of cascade the superior and the subordinate.The utilizable total bandwidth formula of AAL2PATH is as follows:
The utilizable total bandwidth of AAL2PATH=physics total bandwidth-∑ (NCP bandwidth+CCP bandwidth+ALCAP bandwidth+IPOA bandwidth).Wherein, NCP is the NodeB control port, and CCP is a communication control port, and ALCAP is an Access Link Control Application Protocol, and IPOA is that (IP over ATM) is the Internet Protocol (IP) on the asynchronous transfer mode (ATM).
Need to prove that above-mentioned sum formula is to all the NodeB summations under the RNC.The physics total bandwidth is 1920kbps by the transmission bandwidth decision of reality as 1 E1 physics total bandwidth.
NodeB is cascaded as example with two-stage, its connected mode is: RNC links to each other with higher level NodeB1 by Iub interface, higher level NodeB1 links to each other with the NodeB2 of cascade subordinate, and RNC is that the physics total bandwidth is 1920kbps with only disposing 1 E1 with its first order NodeB Iub that directly links to each other transmission.
If the NCP=32kbps of each NodeB carrying, CCP=32kbps, IPOA=64kbps, ALCAP=32kbps, then
The utilizable total bandwidth of AAL2PATH=(1920-∑ (32+32+32+64)) kbps=1600kbps.
According to the prior art bandwidth allocation methods, the resource of distributing for cascade higher level NodeB1 is as follows:
NCP＝32k，CCP＝32k，IPOA＝64k，ALCAP＝32k，AAL2PATH＝800kbps
The resource of distributing for the NodeB2 of cascade subordinate is as follows:
NCP＝32k，CCP＝32k，IPOA＝64k，ALCAP＝32k，AAL2PATH＝800kbps
Be each NodeB all fixed allocation the bandwidth of 800kbps.
Prior art has adopted the fixed allocation bandwidth mode to distribute the AAL2PATH bandwidth.Because under the actual operation situation of network, cascade the superior and the subordinate base station often covers different geographical position, the traffic carrying capacity between them is not to equate fully, i.e. the AAL2PATH bandwidth that cascade the superior and the subordinate base station consumes is also unequal.
Therefore, the mode of prior art fixed allocation bandwidth is not shared between cascade the superior and the subordinate base station and is distributed, and is easy to cause a part of base station call amount too many, has surpassed the AAL2PATH bandwidth of distributing and causes call drop.And other a part of base station call amount very little, and the AAL2PATH ability is not given full play of, thereby reduced Iub transmission bandwidth utilization ratio, increased the operation cost of Virtual network operator.
In real network construction and operation, Wideband Code Division Multiple Access (WCDMA) (WCDMA) communication system operator is often rented third-party transmission equipment or transfer resource, carry out the Iub transmission between RNC and the NodeB, therefore the level of resources utilization of Iub transmission bandwidth is low, rent the operator of transmission equipment like this for needs, operation cost increases.

Under initial condition, described current available bandwidth is that the Iub transmission always can utilize transmission bandwidth to deduct NCP bandwidth, CCP bandwidth, ALCAP bandwidth, IPOA bandwidth income value.When user of the every permission of RNC inserted, the value of current available transmission bandwidth just reduced the Iub transmission bandwidth that this user's actual needs consumes.And when a user inserted, the value of current available transmission bandwidth just increased the Iub transmission bandwidth that this user's actual needs consumes.
And user's actual needs is to determine in the access request that contains QoS parameter of receiving according to RNC.
Fig. 4 is the shared collocation method of RNC based on one group of cascade NodeB access.
Referring to shown in Figure 4, realize that specific embodiments of the invention may further comprise the steps:
Step 401:RNC is that every group of cascade NodeB AAL2 road is provided with a global variable Aal2PathBandWidthUsed through available bandwidth.
The Iub transmission always can utilize bandwidth to be T between step 402:RNC and the one group of cascade NodeB,
Suppose that the utilizable total bandwidth of AAL2PATH is TotalAal2PathBandWidth, then, TotalAal2PathBandWidth=T-∑ (NCP bandwidth+CCP bandwidth+ALCAP bandwidth+IPOA bandwidth)
Attention: above sum formula is NCP, CCP, ALCAP, the IPOA bandwidth summation to all NodeB configurations of this group cascade NodeB.
Step 403:RNC is TotalAal2PathBandWidth to the AAL2PATH bandwidth of any one the NodeB configuration among this group cascade NodeB.
Step 404: initialization Aal2PathBandWidthUsed, Aal2PathBandWidthUsed is set to TotalAal2PathBandWidth.
Step 405: when RNC is in operation when detecting i user and initiating to insert any one NodeB among this group cascade NodeB, suppose that the Iub transmission bandwidth that this user will consume is UserBandWidth (i), judge that whether Aal2PathBandWidthUsed is more than or equal to UserBandWidth (i), if greater than, then execution in step 6, otherwise, execution in step 7.
Step 406:RNC allows i user successfully to insert, and, Aal2PathBandWidthUsed=Aal2PathBandWidthUsed-UserBandWidt h (i).
Step 407:RNC refuses i user and successfully inserts, and Aal2PathBandWidthUsed does not revise.
Any one NodeB in RNC is in operation this group of detection cascade NodeB, there be j user to initiate to connect when discharging, suppose that the Iub transmission bandwidth that this user has consumed is UserBandWidth (j), then Aal2PathBandWidthUsed=Aal2PathBandWidthUsed+UserBandWidt h (j).
After this, when new user inserted, whether RNC repeating step 405 allowed new user's access with decision.When the user tore chain open, RNC repeating step 408 was to regain the AAL2PATH bandwidth resources of having distributed.
Need to prove that RNC is TotalAal2PathBandWidth to the AAL2PATH bandwidth of any one the NodeB configuration among this group cascade NodeB.
In a word, the above is preferred embodiment of the present invention only, is not to be used to limit protection scope of the present invention.
