The multimedia broadcasting of the embodiment of the invention and the resource allocation methods of multicast service and radio network controller divide into groups according to adjacent S A by the SA to multimedia broadcasting and multicast service, and then according to adjacent S A is carried out resource allocation, to improve physical resource utilization.
Before the embodiment of the invention was described in detail, the notion that earlier embodiment of the invention is related to was elaborated, and is beneficial to better understand the present invention.
Independent SA, the overlay area of independent SA and the overlay area of other any SA do not have overlapping;
Adjacent S A set comprises at least two SA, the zone that successively open by overlapping covered formation one each other the overlay area of described at least two SA.
Under the various situations as shown in Figure 2, SA1, SA2, SA3 and SA4 constitute an adjacent S A set, but under the various situations described in Fig. 3, SA1, SA2, SA3 and SA4 do not constitute an adjacent S A set, certainly, should be appreciated that two zones link to each other but the geographic area that do not have the SA (promptly the overlay area of two SA is tangent) of overlapping region to be covered does not belong to the zone of successively opening yet.
As shown in Figure 4, the method for the embodiment of the invention comprises:
In specific embodiments of the invention, need all carrying SA of described MBMS business are distributed formation SA combination according to syntople,, can realize by the following method at this:
At first set up a SA in abutting connection with SA tabulation, this tabulation has comprised with this SA and has been in SA in the adjacent S A set;
Obtain the SA with neighbouring relations of MBMS traffic resource assignment request;
Obtain the SA in the SA tabulation that is in a SA in the carrying service regions of physical source distributing request, form a SA combination, that is to say that SA in this SA combination is the union of adjacent S A of these SA of getting access to and itself with a SA;
If there are not neighbouring relations in certain SA and other SA in the physical source distributing request, then this SA is separately SA combination;
In specific embodiments of the invention, can obtain adjacent S A information by configuration adjacent S A information and the mode that is recorded in database, can certainly be other modes that can realize this purpose, be not described in detail at this.
Method according to the embodiment of the invention, it is the time slot TS4 of carrier frequency F1 that supposing the system is reserved physical resource, as shown in Figure 1, wherein the factor frequently of drawing together of TS4 is the MBMS service area SA1 that preceding 8 code channels of SF=16 have been assigned to carrying MBMS A business, and back 8 code channels have been assigned to the service area SA3 of carrying MBMS A business.
The professional B of current new MBMS need carry out the distribution of physical resource, and the professional B of wherein new MBMS is: carrying service regions is SA1, SA2, SA3; Needed physical resource is to draw together frequently that the factor is 8 code channels of SF=16, and wherein SA1, SA2 are adjacent, and SA3 is independent with respect to SA1, SA2;
According to the method for the embodiment of the invention, in step 42, carrying service regions SA1, SA2, SA3 will be divided into { SA1 SA2} and { two SA of SA3} combination, { the included SA (SA1 and SA2) of SA1 SA2} forms an adjacent S A set, and { SA3} is independent SA.
In step 43, suppose that { SA1 SA2} carries out physical source distributing, as shown in Figure 1, has been assigned to the MBMS service area SA1 of carrying MBMS A business owing to preceding 8 code channels for the SA combination earlier, so can't distribute to SA combination { SA1 SA2}, but because back 8 code channels are assigned to carrying MBMS
The service area SA3 of A business does not distribute to SA1 or SA2, therefore back 8 code channels can be distributed to the service area SA1 and the SA2 of carrying MBMS B business.
Be SA combination { after SA1 SA2} carries out physical source distributing, { SA3} carries out physical source distributing for the SA combination, because back 8 code channels are assigned to the service area SA3 of carrying MBMS A business, so can't distribute to SA3, but because preceding 8 code channels only are assigned to the SA1 of carrying MBMS A business, do not distribute to SA3, therefore preceding 8 code channels can be distributed to the service area SA3 of carrying MBMS B business.
Actual physical resources pond after the Resources allocation as shown in Figure 5, wherein preceding 8 code channels are distributed to the service area SA3 of carrying MBMS B business and the service area SA1 of carrying MBMS A business, 8 code channels in back are distributed to the service area SA1 and the SA2 of carrying MBMS B business, and the service area SA3 of carrying MBMS A business.

Step 44, according to the SA number that the SA combination comprises, the SA combination that sequence arrangement from big to small is all;
In the described step 45, be followed successively by the SA combination according to putting in order and carry out physical source distributing.
The physical resource of considering all SA distribution in the SA combination is identical, and the resource of this distribution simultaneously needs it can not conflict with the actual physical resources generation that has distributed, so the restriction that is subjected to when the more SA of SA number is combined in physical source distributing in the SA combination is bigger, is exemplified below:
Suppose 5 code channels are arranged now, distribute to the A business of SA1 respectively, the B business of SA2, the C business of SA3, the D business of SA4, the E business of SA5, this moment, the carrying SA of new business E was the SA1 that belongs to identical SA combination, SA2, SA3 and SA4, just can only select the 5th code channel this moment, when the carrying SA of new business E is when belonging to the SA1 of identical SA combination and SA2, can select the 3rd code channel this moment, the 4th code channel or the 5th code channel, when the carrying SA of new business E only comprises SA1, can select the 2nd code channel this moment, the 3rd code channel, the 4th code channel or the 5th code channel have 4 kinds of selections.
Consider above-mentioned situation, the SA combination that the method priority allocation SA number of the embodiment of the invention is more, do following benefit like this:
1, because the more SA of SA number combination Resources allocation is restricted greatlyyer, distribute in the back more, its probability that can be allocated successfully is more little, so priority allocation guarantees that SA as much as possible can be allocated successfully, improves the utilance of resource;
2, the resource of all SA distribution of the same business of consideration should be identical as far as possible, to keep more resources is that follow-up business is used, and because the more SA combination Resources allocation of SA number is restricted bigger, it uses the possibility of resource distribution mode of other SA less, and the less SA of SA number combination can use the possibility of resource distribution mode of the more SA combination of SA number bigger, so the more SA combination of priority allocation SA number.
In the step 43 of the embodiment of the invention,, be followed successively by the SA combination and carry out physical source distributing, as shown in Figure 6, specifically comprise the steps: according to the resource situation in current actual physical resources pond
Step 431 is obtained current actual physical resources pond;
