Number, can inquire initial MCS index value.
Further, second mapping table further include MCS grade in the downlink transmission process of base station and TBS parameter and
The mapping relations of PRB number parameter.
It should be noted that above-mentioned VoLTE UL resource occupation selects the speed grade of table for 23.85kbit/s, and other
The VoLTE UL resource occupation selection table of speed grade can equally obtain in a manner mentioned above, as speed grade is
The VoLTE UL resource occupation of 12.65kbit/s selects table, the embodiment of the present invention to this with no restriction.
Step 304, the base station is adjusted for the initial MCS index value, obtains specific MCS index value；
In a kind of concrete application of the embodiment of the present invention, the base station is adjusted for the initial MCS index value, is obtained
Obtain specific MCS index value；Specifically, the base station gets maximum MCS index value；The base station judges the initial MCS
Whether index value is less than the maximum MCS index value；When the initial MCS index value is less than the maximum MCS index value, then
Determine that the initial MCS index value is the specific MCS index value.
For example, the maximum MCS index value can be the MCS 26 in upper table, and the initial MCS index value is MCS
5, because initial MCS index value is less than the maximum MCS index value, determine that the corresponding MCS index value of MCS 5 is specific MCS
Index value.
Step 305, the base station obtains the corresponding TBS parameter of the specific MCS index value and PRB number parameter；
In the embodiment of the present invention, base station obtains the corresponding TBS parameter of the specific MCS index value and PRB number parameter, i.e.,
Base station inquires the corresponding TBS parameter of the specific MCS index value and PRB number parameter according to the first mapping table, is such as opening
When RoHC function, the TBS parameter of MCS 5 are as follows: 600 and PRB number parameter are as follows: 7.
Step 306, the TBS parameter and PRB number parameter are sent to the UE by transformat by the base station.
Further, the parameters such as TBS parameter, PRB number parameter and order of modulation are passed through transformat by base station
(Transport Format) is sent to the UE；Voice data is sent to the base station according to above-mentioned parameter by UE, is completed
Uplink process.
In the embodiment of the present invention, the base station obtains signal-to-noise ratio SINR information；The base station for the SINR information into
Row amendment, obtains revised SINR information；It is closed according to the revised SINR information and the second preset mapping the base station
System inquires initial MCS index value；The base station is adjusted for the initial MCS index value, obtains specific MCS index
Value；The base station obtains the corresponding TBS parameter of the specific MCS index value and PRB number parameter；The base station is by the TBS
Parameter and PRB number parameter are sent to the UE by transformat；In the embodiment of the present invention, optimize in VoLTE voice number
According to the selection mode of middle MCS index value, and solves and asked due to accidentally wrapping re-transmission bring time delay, shake and data packet disorder etc.
Topic ensures that VoLTE voice data in the reliability of air interface transmission, promotes the experience that user is directed to VoLTE.
In order to make those skilled in the art more fully understand the embodiment of the present invention, carried out below by way of a specific example
Illustrate:
In step 1, the selection course of the downlink MCS grade of voice user, the CQI information reported is modified first,
CQI information amendment need to follow the mode for slowly rising rapid downward regulation；
User is more sensitive to time delay and quality in VoLTE business, when meeting MCS and adjusting upward condition, answers
This is slowly raised, the influence for avoiding the rapid change zone of wireless environment from；It is deteriorated in voice quality and needs to adjust downwards MCS with full
When the requirement of sufficient Bler (Block Error Ratio, BLER(block error rate)) etc., it should big step-length rapid downward regulation MCS to meet language
The requirement of sound quality；The adjustment of uplink CQI information is adjusted using the SINR information of SRS measurement, selects the mode and downlink of MCS
Selection mode it is consistent；
Step 2 quickly selects MCS grade and right according to revised CQI in VoLTE uplink and downlink resource occupation selection table
The TBS parameter answered selects highest MCS as initial MCS index value in the case where meeting Bler and requiring；Downlink resource occupancy situation
Table (the first mapping table) is selected referring to VoLTE DL resource occupation；Ascending resource, which is occupied, selects table referring to VoLTE UL resource occupation
(the second mapping table)
Step 3, initial MCS index value and the maximum MCS index value that downlink limits compare, and select the MCS of smaller value
As specific MCS index value；
Step 4, using the corresponding TBS index of specific MCS index value and PRB number as selected resource as the secondary scheduling
Resource information output；
It should be noted that the payload of typical VoLTE 23.85kbps data packet is 32byte, the packet header of IPv6 is
The packet header of 60byte (byte), IPv4 (Internet Protocol Version 4, Internet protocol fourth edition) are
40byte, current network are transmitted using IPv4 and require to open RoHC function.In the feelings for opening RoHC header compression algorithm
Under condition, it is 576bits that VoLTE, which activates phase data package size, and in the case where closing RoHC header compression algorithm, VoLTE activates the phase
Data package size is 848bits.According to the size of VoLTE business data packet, in conjunction with existing communication protocol
The smallest 576 value of being greater than is 584 in 36.213Table7.1.7.2.1-1, TBS parameter, and selection is greater than and is close to 576
TBS parameter of the train value as downlink resource, the smallest 848 value of being greater than is 872 in TBS parameter, and selection is greater than and close to 848
TBS parameter of the series of values as ascending resource generates VoLTE uplink and downlink resource occupation and selects table according to above-mentioned parameter, i.e., and the
One mapping table and the second mapping table.
In a kind of preferred embodiment of the embodiment of the present invention, since when MCS grade is MCS0, the PRB quantity of occupancy is bright
It is aobvious than other MCS more grades；When opening RoHC function, PRB quantity is 22, when closing the closing of RoHC function, PRB
Quantity is 32, under normal circumstances user occur being in when MCS0 wireless quality it is very poor in the case where, even if scheduling perception
Very poor situation carries out specially treated or sheet so general base station system thinks to belong to abnormal conditions when MCS grade is MCS0
It is secondary without scheduling.
