If specifically, the default GBR values of the terminal are more than the predetermined threshold value, step 305 is performed, if the terminal
Default GBR values are less than or equal to the predetermined threshold value, then perform step 306.
305th, the resource request of the terminal is refused in the base station.
If specifically, the terminal is to support the Cell Center User of COMP technologies, and the default GBR values of the terminal are big
Then it is difficult the terminal is reached default GBR values by the resource of cooperation district in predetermined threshold value, or, pass through collaboration in time
The resource of cell enables to the terminal to reach the default GBR values, will also result in larger interference, gain is smaller, now terminal
The resource request of the terminal can directly be refused.
306th, the base station judges the remaining interface-free resources of the main plot and the cooperation district corresponding to the main plot
Whether the interface-free resources interface-free resources request message of the terminal corresponding to are more than or equal to.
It should be noted that the remaining interface-free resources of the main plot, are the base station can use according to the main plot
Interface-free resources and the terminal are in the channel quality information of the main plot, and the scheduling of resource for adjusting the main plot obtains

For example, if the terminal is supports the Cell Center User terminal of COMP technologies, and the terminal is default
GBR values be less than predetermined threshold value GBR user, the base station judges that the residue of the main plot and the cooperation district eats dishes without rice or wine to provide
Whether source block disclosure satisfy that the demand of the default GBR values of the terminal, if can be with the main plot and the cooperation district
Remaining interface-free resources be more than or equal to the terminal interface-free resources request message corresponding to interface-free resources, if cannot,
The remaining interface-free resources of the main plot and the cooperation district are less than corresponding to the interface-free resources request message of the terminal
Interface-free resources.
Again for example, the terminal for support COMP technologies non-GBR terminals, the base station judge the main plot with
Whether the remaining interface-free resources block of the cooperation district disclosure satisfy that the access demand of the terminal, if can be so that the master is small
The remaining interface-free resources of area and the cooperation district, which are more than or equal to corresponding to the interface-free resources request message of the terminal, eats dishes without rice or wine
Resource, if cannot, the remaining interface-free resources of the main plot and the cooperation district are less than the interface-free resources of the terminal
Interface-free resources corresponding to request message.
If the base station judges that the remaining interface-free resources of cooperation district corresponding to the main plot and the main plot are more than
Equal to the interface-free resources corresponding to the interface-free resources request message of the terminal, then step 307 is performed, if the base station judges institute
Interface-free resources request of the remaining interface-free resources less than the terminal for stating cooperation district corresponding to main plot and the main plot disappears
The corresponding interface-free resources of breath, then perform step 308.
307th, the remaining interface-free resources of the main plot and the cooperation district are distributed to the terminal by the base station.
308th, the interface-free resources of the base station dismounting other-end distribute to the terminal.
It should be noted that for Cell Edge User, base station is either by step 306 by main plot and cooperation district
Remaining interface-free resources distribute to the terminal, or by step 308 remove other-end interface-free resources distribute to it is described
Terminal, preferentially distribution disturbs less RB resources to give the terminal terminal for the base station, specifically, the base station judges
Which RB resource is smaller to terminal interference can various ways, such as base station detection can each distribute to the end
Interference size of the RB resources at end to the terminal, less RB resource allocations will be disturbed to the terminal to the terminal so as to realize.
In addition, for being removed the terminal of resource, non-the GBR user and GBR user of equal priority, meeting
Under the conditions of GBR user rates, the speed of GBR user is reduced first, if being unsatisfactory for the demand of user's access, reduces Non-GBR
The speed of user.If reduction of speed is unsatisfactory for requiring, low priority user dedicated bearer is removed, if dedicated bearer is unsatisfactory for the end
The interface-free resources demand at end, then remove the default bearing of low priority user.
