Therefore, to ensure after activating semi-persistent scheduling, base station can timely respond to the data transfer demands of end side, base
Stand when distributing resource for uplink voice traffic is the report of terminal distribution buffer memory（BSR）Space, storage report is changed for carrying,
So that base station can obtain the buffer memory report of terminal, ascending resource is distributed in time.
But in aforesaid way, since speech business valid data length is shorter, and base station is when distributing ascending resource
Additional allocation space is reported for buffer memory, therefore will reduce the capacity of group in cell, and for many industry users, need
Cell interior energy is wanted to accommodate more group.Especially for the speech business of small speed, the demand of industry user is not reached.
But if when uplink voice traffic distributes resource, if not distributing buffer status report space, in semi-static activation
Period, terminal and eNB do not handle dispatch request, and when the class of business that terminal is supported is more, for example terminal supports voice at the same time
Business and data service, since terminal cannot report buffer memory in time, data service cannot get ascending resource, and will cause data
Service disconnection.
The content of the invention
The application provides a kind of distribution method of uplink semi-persistent resource, can be in the base for ensureing data service and being not disrupted
On plinth, cell is set to accommodate more groups.
To achieve the above object, the application adopts the following technical scheme that：
A kind of distribution method of uplink semi-persistent resource, including：
Determine that situation is established in the current carrying of terminal；Situation is established according to the carrying, uplink semi-persistent is carried out for terminal
The distribution of resource；
Wherein, if the carrying currently established is only single speech business carrying and signaling bear, uplink semi-persistent is being carried out
The space of not reserved buffer memory report during resource allocation；
If the carrying currently established includes speech business carrying and at least one dedicated bearer, uplink semi-persistent is being carried out
The space of buffer memory report is reserved during resource allocation.
It is preferred that the space that not reserved buffer memory is reported when carrying out uplink semi-persistent resource allocation, the then mandate distributed
Bit number is the sum of two packet header of layer and group's voice packet size.
It is preferred that the space of buffer memory report, then the mandate ratio distributed are reserved when carrying out uplink semi-persistent resource allocation
Special number is two packet header of layer, group's voice packet size and buffer memory report the sum of reserved bit number.
It is preferred that the current carrying of the definite terminal is established situation and is included：The high level of base station side is established business every time and is held
Uplink scheduling device is notified during load, uplink scheduling device preserves the carrying number and species of activation.
As seen from the above technical solution, in the application, situation is established according to the carrying of user terminal, uplink is carried out for terminal
The distribution of semi-persistent resource.Wherein, if the carrying currently established includes speech business carrying and at least one dedicated bearer, say
It is bright to carry out other business data transmissions in addition to speech business, therefore reserve when carrying out uplink semi-persistent resource allocation slow
The space of storage report, so as to ensure to carry out data transmission in time, is not disrupted data service.If the carrying currently established is only
For single speech business carrying and signaling bear, then explanation only speech business, therefore when carrying out uplink semi-persistent resource allocation
The space of not reserved buffer memory report, so that cell accommodates more groups.By the above-mentioned means, it can ensure data service
On the basis of being not disrupted, cell is set to accommodate more groups.
Brief description of the drawings

Embodiment
In order to which the purpose of the application, technological means and advantage is more clearly understood, the application is done below in conjunction with attached drawing
It is further described.
Fig. 1 is the distribution method flow chart of uplink semi-persistent resource in the application.As shown in Figure 1, this method includes：
Step 101, before uplink semi-persistent resource allocation is carried out, determine that situation is established in the current carrying of terminal.
Determine that value volume and range of product is established in the current carrying of terminal.Business specifically can be established every time in the high level of base station side to hold
Uplink scheduling device, the carrying number and species of the record activation of uplink scheduling device are notified during load.
Step 102, the distribution of situation progress uplink semi-persistent resource is established according to the current carrying of terminal.
Skilled person will appreciate that carried accordingly before any business is carried out, it is necessary to be established for business, so if
Carried currently without being established for certain business, then illustrate that user terminal does not establish corresponding business, there will not be corresponding business
Data need to transmit.Therefore, situation is established it is known that terminal traffic establishes situation according to the current carrying of terminal.And
After terminal activation semi-persistent scheduling, if user terminal does not establish data service, also there will be no the respective counts of data service
According to transmission, also avoid the need for reporting buffer memory to report, therefore when distributing uplink semi-persistent resource, buffer memory report can not be reserved
The space of announcement, to save resource, increases the voice group capacity in cell；If the data service that user terminal is established, just has
Corresponding data transfer may be carried out, then needs to report buffer memory to report, to carry out the data transfer of data service in time, is ensured
