Embodiment 1

[0025] figure 1 It is a schematic flowchart of a method for scheduling an integrated uplink GBR service provided by Embodiment 1 of the present invention. Such as figure 1 As shown, the scheduling method of the uplink GBR service includes the following steps:

[0026] 101. The base station presets the maximum data volume corresponding to the maximum bit rate MBR and the minimum data volume corresponding to the guaranteed bit rate GBR within a unit period for the terminal.

[0027] In this embodiment, the base station pre-configures the maximum bit rate (Maximum Bit Rate, MBR for short) corresponding to the GBR service of the terminal according to the regulations in the 3rd Generation Partnership Project (The 3rd Generation Partnership Project, 3GPP for short). It is stipulated in the 3GPP agreement that the data transmission rate of the GBR service between the terminal and the base station cannot exceed the preset MBR. The base station takes the amount of data sent by the t...

Embodiment 2

[0041] figure 2 It is a schematic flowchart of an uplink GBR service scheduling method provided in Embodiment 2 of the present invention. Such as figure 2 As shown, the uplink GBR service scheduling method includes the following steps:

[0042] 201. The base station presets the maximum data volume corresponding to the MBR and the minimum data volume corresponding to the GBR within a unit period for the GBR service of the terminal.

[0043] 202. The base station acquires the amount of GBR data sent by the terminal in the uplink data transmission subframe in the current period.

[0044] For the specific process of step 201 to step 202, refer to step 101 to step 102 in the first embodiment above, which will not be repeated here.

[0045] 203. The base station acquires a first difference between the minimum data amount and the GBR data amount.

[0046] 204. If the first difference is greater than zero, the base station determines that air interface resource scheduling needs ...

Embodiment 3

[0066] image 3 It is a schematic structural diagram of a base station provided by Embodiment 3 of the present invention. Such as image 3 As shown, the base station includes: a preset module 31 , an acquisition module 32 , a judgment module 33 and a scheduling module 34 .

[0067] Wherein, the preset module 31 is configured to preset the maximum data volume corresponding to the MBR and the minimum data volume corresponding to the GBR within a unit period for the GBR service of the terminal.

[0068] In this embodiment, the preset module 31 pre-sets the corresponding MBR for the GBR service of the terminal according to the regulations in the 3GPP protocol. Moreover, the data transmission rate of the GBR service between the terminal and the base station stipulated in the 3GPP protocol must be lower than the preset MBR. The preset module 31 presets the maximum amount of data that the terminal can send to the base station with the preset MBR in each period, that is, the maximu...

Abstract

The invention provides an uplink GBR (Guaranteed Bit Rate) service scheduling method and a base station. The method comprises that a base state presets the maximum data size corresponding to a MBR (Maximum Bit Rate) and the minimum data size corresponding to the GBR in a unit period for the GBR service of a terminal; the obtained GBR data size sent by an uplink data transmission subframe of the terminal during a current period is counted; whether or not the air interface resource scheduling is carried out is determined according to the maximum data size, the minimum data size and the GBR data size; and if the air interface resource scheduling is determined to be carried out, corresponding air interface resources are granted according to a current to-be-transmitted GBR data size obtained from the BSR (Buffer Status Report) reported by the terminal. According to the invention, the base station determines whether or not the terminal carries out the air interface resource scheduling according to the actually-transmitted GBR data size, the maximum data size and the minimum data size of the terminal during the current period, and when the scheduling is needed, the air interface resources corresponding to the current to-be-transmitted GBR data size are granted to the terminal, so that the scheduling frequency is lowered, and the occupation of CCE (Control Channel Element) resources is reduced.

Description

technical field [0001] The present invention relates to the communication field, in particular to a scheduling method and a base station for uplink GBR services. Background technique [0002] Guaranteed Bit Rate (GBR) services have relatively high requirements on transmission delay, and the scheduling priority of GBR services is only lower than that of signaling data. In Long Term Evolution (LTE) systems, GBR is generally given priority. The rate of business. [0003] At present, the base station will use the data that needs to be scheduled before the TTI as the data to be scheduled by the terminal in each transmission time interval (Transmission Time Interval, TTI) according to the set GBR, through the control channel element (Control Channel Element , CCE for short) authorizes the terminal, and the terminal uploads data to the base station on the authorized air interface resource. [0004] In the existing GBR service scheduling method, the base station needs to schedule ...
