Embodiment
For the purpose that makes the embodiment of the invention, technical scheme, and advantage clearer, below the technical scheme that the embodiment of the invention provides is elaborated with reference to accompanying drawing.
See also Fig. 1, the resource allocation methods flow chart for the embodiment of the invention provides comprises:
Step 101: the base station obtains the resource requirement statistic of relay station, and wherein, described resource requirement statistic can comprise: at least one in forward channel resource requirement statistic and the reverse channel resources demand statistic;
In actual applications, described resource requirement statistic can be added up by the base station, and the resource requirement statistic that then described base station obtains relay station specifically comprises:
The stock number that base station periodicity or acyclic statistics relay station need, wherein, the stock number that the base station can adopt following several method statistics relay station to need:
One, this relay station average discharge in periodicity or the acyclic statistics Preset Time calculates (estimation) and goes out resource requirement statistic (at least one in forward channel resource requirement statistic and the reverse channel resources demand statistic).Such as, can preestablish the average discharge of base station in 60 minutes statistics relay stations 30 minutes, and according to described average discharge computational resource requirements statistic.
Two, when estimation forward channel resource requirement statistic, can also pass through the data congestion amount of this relay station by accounting base-station, then,, calculate (estimation) forward channel resource requirement statistic according to described data congestion amount to end side.
Three, when estimation reverse channel resources demand statistic, can also from the reverse channel resources demand information of terminal, obtain the reverse channel resources demand of terminal, then, the reverse channel resources demand of each terminal that statistics gets access to obtains reverse channel resources demand statistic.Wherein, the reverse channel resources demand information is to send to relay station by terminal, and send to the base station by relay station, therefore, in actual applications, the base station is when statistics reverse channel resources demand statistic, and the reverse channel resources demand statistics of obtaining in the reverse channel resources demand information with same relay station transmission obtains the reverse channel resources demand statistic of this relay station together.
Perhaps, described resource requirement statistic can be added up by relay station, then further comprises before the base station obtains the resource requirement statistic of relay station:
Relay station periodically or its stock number that needs of acyclic statistics and is sent to described base station with the resource requirement statistic, and wherein, relay station can adopt following several method to add up it needs stock number:
One, this relay station average discharge in periodicity or the acyclic statistics Preset Time estimates resource requirement statistic (at least one in forward channel resource requirement statistic and the reverse channel resources demand statistic).
Two, when estimation reverse channel resources demand statistic, can also add up the reverse channel resources demand of each terminal, calculate (estimation) reverse channel resources demand statistic, wherein, the reverse channel resources demand of each terminal can obtain from terminal sends to the reverse resource requirement information of base station by relay station.
Three, when estimation forward channel resource requirement statistic, can add up the data congestion amount of current relay station,, calculate (estimation) forward channel resource statistics amount according to described data congestion amount to the terminal direction.
Step 102: the base station is described relay station Resources allocation according to described resource requirement statistic;
In actual applications, step 102 specifically comprises: according to described resource requirement statistic, determine to distribute to the resource quantity and the resource location of described relay station, and described resource quantity and position are sent to relay station.So far finished process into the relay station Resources allocation.
In the technical scheme that the embodiment of the invention provides, owing to being that relay station is current, the resource requirement statistic serves required total resources for terminal in its coverage provides, therefore, the technical scheme that the embodiment of the invention provides is according to the resource requirement statistic, give relay station with the total resources primary distribution of the current needs of relay station, reduce the Signalling exchange quantity between base station and relay station, saved Internet resources.
Further, can communicate with the terminal in its coverage in order to make relay station, said method can further include:
Step 103: relay station is given each terminal according to the communication needs of each terminal with the resource allocation that described relay station distributes, and wherein, each terminal is meant the terminal in the relay station coverage;
In the prior art, the reverse channel resources request of terminal need be arrived the base station again through relay station, and the allocation of radio resources signaling of base station will arrive terminal again through relay station, the time-delay that causes is bigger, influences the service quality to terminal, and, in the existing wireless resource allocation methods, the base station need be distributed special-purpose Radio Resource separately for each terminal in the relay station coverage, has increased Signalling exchange quantity between relay station and base station, has caused network resources waste.And in embodiments of the present invention, the base station is according to the resource requirement statistic, for relay station distributes a resource, by the communication needs of relay station according to each terminal in its coverage, give terminal with this part resource allocation, therefore, the method that the embodiment of the invention provides has reduced the time-delay that resource allocation causes on the one hand, guaranteed the service quality of relay station to terminal, and the Signalling exchange quantity when having reduced resource allocation, the function that has also kept relay station that resource is dispatched on the other hand makes scheduling of resource flexible and efficient, has improved the stability of resource.
It should be noted that in embodiments of the present invention:
1, the base station is that the resource that relay station distributes can be continuous physically, also can disperse.
2, the base station is that the resource that relay station distributes can be not timing, and promptly as long as resource is not initiatively regained in the base station, this resource can be used by relay station always.
3, the base station is that the resource that relay station distributes can preestablish the time, when resource quantity and position being sent to relay station in the base station, can further the time of setting be sent to relay station, at this moment, relay station and base station need be safeguarded a timer separately, after the default time finishes, the described resource of base station automatic drawing back.
4, if relay station has had certain resource, then the base station is when the resource quantity that will distribute to relay station and position send to relay station, whether the resource that can further indicate current distribution substitutes the existing resource of relay station, if substitute existing resource, then need further to indicate resource quantity and the position that needs substitute, if do not substitute existing resource, the then current resource of distributing to relay station will be increased in the existing resource.
5, the resource that relay station has been had, then the base station can also prolong or shorten relay station to having the service time of resource.
6, whole resources of relay station can be reclaimed in the base station.In addition, the part resource of relay station can also be reclaimed in the base station.
