In the application of border, further types of DL can be preset:UL proportioning mode, or do not preset, but directly to DL:UL proportioning side
Formula could be adjusted to update band width configuration scheme, and such change can't affect the protection domain of the application, example hereinafter
Similar, explanation is not repeated.
By above-mentioned process, during facility registration, 4G base station completes the adjustment of corresponding band width configuration scheme
Process.
It should be noted that above-mentioned adjustment process does not have wanting of certainty for the quantity of access device type under 4G base station
Ask, if not accessing any one monitoring device under 4G base station, after it accesses a front end encoding device, will necessarily
Selection increases ascending resource.And if having accessed a decoding device under 4G base station, now, then access a new front end
It is still desirable to increase ascending resource after encoding device, because how the resource before no matter configures, the new front end coding accessing
Equipment is necessarily required to more ascending resources, and increasing ascending resource configuration also just becomes certainty, simply, can increase width to resource
Degree produces impact.For example, accessed the currently employed pattern in 4G base station 1 (4 sub-frame of uplink) of a decoding device, then connect again as
It is contemplated that having accessed decoding device during one new front end encoding device, 4G base station will not significantly increase up money
Source, so, pattern 0 (6 sub-frame of uplink) will not be selected, and only can select pattern 6 (5 sub-frame of uplink).
Step S305,4G base station judges the friendship that the monitoring device whether received message is current registered is reported
Mutually message.
To after the intercepting primarily to ensureing registration process of mutual message, with the change to bandwidth demand for the equipment,
Band width configuration scheme can be adjusted.
If it is judged that being no, represent that this message is not the message that can embody bandwidth demand, in present treatment flow process
It need not be further processed, terminate present treatment flow process.
If it is judged that being yes, then execution step S306.
It should be noted that the present embodiment can embody the message class of bandwidth demand with logon message and two kinds of mutual message
Illustrate as a example type, if other messages also can embody the bandwidth demand of different terminal equipment, similarly may apply to
In the method that the present embodiment is proposed, corresponding handling process can also be increased with reference to the process of mutual message accordingly, so
Change can't affect the protection domain of the application.
Step S306,4G base station obtains entrained bandwidth demand type information and bandwidth demand amount letter in mutual message
Breath.
As shown in figure 5, the schematic diagram of the mutual message under a kind of concrete application scene proposing for the embodiment of the present application.4G
The Media Protocol of this message is passed through in base station：Next udp information is it may be determined that what the transmitting terminal of this mutual message needed
It is upstream bandwidth.In addition, the bandwidth value of this message is passed through in 4G base station：2048kb/s information is it may be determined that it is to upper
The demand of row bandwidth is 2048kbps.
Step S307,4G base station carries out cumulative record to the bandwidth requirement information in the current adjustment cycle.
4G base station combines terminal equipment type, or resource requirement type, carries out cumulative record to resources requirement.
For example, for the cumulative record scene based on terminal equipment type and resources requirement, record result can be concrete
As shown in table 1：
The resources requirement cumulative record result based on terminal equipment type for the table 1
| Terminal equipment type | Required code stream bandwidth |
| Decoding device | 2048kbps |
| Front end encoding device | 4096kbps |
| Decoding device | 1024kbps |
| …… | …… |
And for the cumulative record scene based on resource requirement type and resources requirement, recording result can be specifically as table
Shown in 2：
The resources requirement cumulative record result based on resource requirement type for the table 2
| Resource requirement type | Required code stream bandwidth |
| Downlink bandwidth | 2048kbps |
| Upstream bandwidth | 4096kbps |
| Downlink bandwidth | 1024kbps |
| …… | …… |
Which kind of in specific application scenarios, specifically can be selected according to actual needs using recording mode, so
Change can't affect the protection domain of the application.
Step 308,4G base station judge whether to reach the adjustment cycle.
4G base station equipment carries out timing, according to regular time length separation, resource allocation proposal is carried out periodically adjust
Whole.If reached, execution step S309；
Without reaching, return to step S308, proceed to judge.
The embodiment of the present application illustrates taking the aforesaid Adjusted Option two as trigger condition with the adjustment cycle as a example, in reality
In the application scenarios on border, equally can adopt the processing scheme to receive mutual message as trigger condition, here is no longer separately
Narration, two schemes respectively have pluses and minuses, have discussed above, can be selected according to actual needs, such change
Belong to the protection domain of the application.
Step S309,4G base station determines the ratio of different resource demand according to current cumulative record result.
According to cumulative record situation as shown in table 1 in step S307,4G base station can calculate required for decoding device
Total bandwidth (i.e. downlink bandwidth summation), and the total bandwidth (i.e. upstream bandwidth summation) needed for encoding device, thus, can
To determine the ratio of upstream bandwidth summation and downlink bandwidth summation.
Step S310,4G base station adjusts band width configuration scheme according to percent information.
Equally to preset 7 kinds of DL:Illustrate as a example the application scenarios of UL proportioning mode, if determine in step S309
Ratiometric result is 11：29, then in default 7 kinds of DL:In UL proportioning mode, a closest conduct of selection percentage result is
Whole adjustment result.
To default 7 kinds of DL:It is as follows that UL proportioning mode carries out ratio accounting result：
Pattern 0：1 radio frames includes 2 descending sub frames, 6 sub-frame of uplink and 2 special subframes, i.e. up-downgoing ratio
Example 3：1；
Pattern 1：1 radio frames includes 4 descending sub frames, 4 sub-frame of uplink and 2 special subframes, i.e. up-downgoing ratio
Example 1：1；
Pattern 2：1 radio frames includes 6 descending sub frames, 2 sub-frame of uplink and 2 special subframes, i.e. up-downgoing ratio
