Description

Service processing method, transceiving equipment and computer readable storage medium

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a service processing method, a transceiver device, and a computer-readable storage medium.

Background

When the existing network TD-LTE tests the uploading and downloading rates, when the uplink and downlink data services are concurrent with the voice VOLTE services, the rate of the uplink and downlink data services can be reduced by 10% -20%. This is because when the media controls the MAC layer packet in the current network, the data service and the voice service data are concatenated in one packet. At this time, the target BLER (block error rate) of the data service is 10%, and the target BLER of the voice service is 1%, in order to meet the requirement of the voice service, at the transmission stage of the voice VOLTE service, the modulation and coding strategy MCS (or coding rate Re) value corresponding to the SINR (signal to interference plus noise ratio) reported by the data service is reduced, that is, less transmission data is selected according to the SINR-MCS curve (link emulation BLER-SINR-MCS curve) corresponding to the target BLER 1%, so that when the voice service and the data service are transmitted in the same packet, the target BLER of the voice VOLTE service is 1%.

That is, in the prior art, the MCS corresponding to the SINR reported by the terminal is reduced by 3-4 steps in the whole voice call time period, which results in a reduction of the full bandwidth rate of the LTE system by 10% -20%; that is, the rate of the VOLTE voice service 40K may cause the full bandwidth rate of the LTE system to be reduced by 4-5M, which seriously affects the user experience and reduces the system utilization rate.

As can be seen from the above, in the prior art, in the whole stage of the VOLTE voice call, the base station may reduce the target BLER of the data service to be the same as the target BLER of the VOLTE voice service, which results in that the uplink and downlink rate in the whole voice stage is reduced by 10% to 20%.

The service processing method provided by the embodiment of the present invention is further described below with reference to two sides of the sending end and the receiving end, where a final target block error rate corresponding to data of the data service is, for example, 10%, a final target block error rate corresponding to target voice service data is, for example, 1%, and data of the voice service is repeated twice.

In view of the above technical problems, embodiments of the present invention provide a service processing method, so that when a VOLTE voice service and an uplink and downlink data service in a TD-LTE system are concurrent, it is ensured that the VOLTE is transmitted at a target value with a BLER of 1%, and meanwhile, the uplink and downlink data service is transmitted under a criterion with a BLER of 10%, so that it is ensured that the uplink and downlink data service is not affected by the VOLTE voice service and reduced when data are concurrent, and a system utilization rate and a user experience degree are improved.

The embodiment of the invention provides the following four specific implementation modes:

firstly, the improvement of the VOLTE voice target BLER from 1% to 10%, the improvement of the VOLTE voice target BLER to 10% in the field test can also be guaranteed, but the VOLTE voice performance requirement is higher than that of common service transmission.

Second, the MAC layer is divided into logical channel groups (data service and voice service are divided into logical channels in the MAC layer by cascade): that is, if the qos class flag QCI is 1 to carry the corresponding logical channel, the packet is not segmented in cascade with other logical channels at the MAC layer, but is packaged separately, so as to distinguish data traffic from voice traffic. The data service and the voice service adopt different modulation and coding modes and are transmitted by separating different physical resources (time slots), and the voice service does not influence the data service transmission (the physical layer schedules different MAC PDU-MAC protocol data units in a time division mode, the voice service and the data service are transmitted at different times, the data service rate is guaranteed, and meanwhile, the voice service is ensured to be transmitted correctly). However, the voice data packet of this method is very small, TURBO coding efficiency is not high, and meanwhile, only scheduling voice service in a certain time slot will result in a low rate of this time slot, and also will result in a scenario without data service when existing voice service is available.

And thirdly, distinguishing whether data of the QCI-1 service exists or not when the fine scheduling is performed, namely the base station scheduling. The MCS is reduced only for the traffic with QCI of 1, and is not reduced otherwise (i.e. the MCS is reduced by the voice traffic target BLER for the data traffic and the voice traffic concurrently scheduled time slots only when the QCI of 1 is present). Voice packets of VOLTE are generally 20ms or 40ms one (that is, voice service is sent once every 20ms or 40 ms), if MCS is reduced only when QCI ═ 1 data is transmitted, there is almost no influence on the overall downlink rate (that is, MCS transmission data is not reduced for 19ms and 39ms without VOLTE voice data being sent), and when VOLTE voice service and data service are ensured to be concurrent, the uplink and downlink rate of the LTE system is basically unchanged.

Fourthly, when the packet is packaged at the MAC layer, VOLTE data can be repeated, the target BLER of the VLOTE voice service is improved from 1% to 10% in a mode similar to a spread spectrum effect, the target BLER is the same as that of the data service, and then an SINR-MCS curve corresponding to the target BLER 10% is selected to select and adjust a coding mode. And finally, when VOLTE data is received, the target BLER can reach 1%, and when VOLTE data is transmitted, the coding mode is adjusted by adopting SINR-MCS corresponding to the target BLER of 10%. The advantage of this method is that the data is repeated only for the data of the logical channel with QCI ═ 1, and there is no influence on other logical channels, the VOLTE data packet is small, and the repeated part has no obvious influence on the uplink and downlink rates.

The purpose of the above four specific implementation manners is to improve target BLER 1% to 10% of the VOLTE voice service, which is the same as the data service, and is used to improve the subsequent modulation and coding rate, remove the influence of the voice service on the modulation and coding manner of the data service, and at the same time, not affect the target BLER 1% received by the VOLTE voice service.

The following description mainly refers to a fourth specific implementation.

Because the logical channel begins to multiplex at the MAC layer, the PDCP layer and the RLC layer are based on the bearing group package; so the data on the bearer with repetition QCI 1 can be repeated in PDCP layer, RLC layer and MAC layer, after which the different logical channel multiplexes are grouped and cannot be distinguished from different bearers or different logical channel data.

The fourth specific implementation manner may be understood as a scheme for increasing the data service rate when the data service of the TD-LTE system and the VOLTE voice service are concurrent, and by repeatedly transmitting the VOLTE service data carried by QCI ═ 1 once, the transmission target BLER 1% of the VOLTE voice service is increased to the data service target BLER 10%. This is because, when 10% of BLER data is transmitted and received twice, the reception target BLER is lowered to 10% × 10% to 1%.

For the fourth specific implementation, more specifically, the following is shown:

first, if the QCI is repeated at the PDCP layer for the VOLTE voice service data carried by 1, a PDCP pdu (PDCP protocol data unit, refer to TS 36.323) is shown in fig. 3, where D/C represents a data/control flag bit, and Oct represents a byte:

a) firstly, determining VOLTE voice service borne by QCI (quaternary ammonium identity) -1;

i. the sending end repeats the PDCP PDU packet, namely the Data part repeats Data twice, and the sequence number SN is not changed; doubling PDCP PDUs to form a data packet;

ii, the transmitting end repeats the PDCP PDU packet, or the Data part is not changed, and SN is added with 1; repeating PDCPPDUs to form two data packets;

b) the subsequent flow is unchanged from the existing flow of the LTE system: sending to RLC, MAC, physical layer (PHY layer), sending out through wireless circuit;

c) a receiving end receives a PDCP packet (a repetition mode and a coding mode are appointed in advance with a transmitting end) uploaded by an RLC layer, and decodes the PDCP packet;

It should be noted that the processing flow at the receiving end may specifically correspond to the processing flow at the transmitting end, and is a reverse order of the processing flow at the transmitting end, but the invention is not limited thereto.

Regarding the above-mentioned receiving end and sending end appoint the repetition mode and the coding mode in advance, because when considering that the receiving end PDCP layer, RLC layer and MAC layer receive VOLTE voice data, because the received data is already the physical layer demodulation decoded data, the data repeated twice can not output correct data by merging; at this time, a precoding mode needs to be added to the VOLTE voice data at the transmitting end, so that the data can be correctly output after the receiving end decodes the VOLTE voice data.

Specifically, the encoding method includes the following three methods:

a) as the physical layer, the Turbo coding is adopted, so that the coding efficiency and the accuracy are high, and meanwhile, the physical layer already has the Turbo code;

b) CRC error correction coding is adopted, namely 16-bit CRC is added behind the two repeated parts of data, so that the receiving end can correctly output the data after combination;

c) repeated coding, namely, repeated volte voice data for 3 times, the receiving end can correctly output the data after merging, and the coding efficiency of the method is lower than that of the former two methods.

As can be seen from the above, the fourth specific implementation manner, i.e. the repeated VOLTE data, can increase the target BLER 10% for VOLTE voice transmission by repeatedly transmitting the data, and simultaneously ensure that the actually received target BLER is 1%, and the same MCS and coding method are adopted as those for data service transmission, thereby eliminating the influence of the voice service on the data service when the data service and the voice service are packaged and transmitted together; in addition, the sending end needs to perform precoding processing on the repeatedly sent data, and the precoding mode adopts Turbo coding, repeated coding or CRC (cyclic redundancy check) to ensure that the receiving end receives the combined data and then correctly outputs the combined data.

In summary, in the scheme provided by the embodiment of the present invention, when the TD-LTE system data service and the voice service are concurrent, the uplink and downlink data services and the VOLTE voice service use the same target BLER to select the SINR-MCS curve to obtain a higher-order modulation coding scheme through a fine scheduling or repeating mode of VOLTE voice data, so that the problem of reducing the rate by 10% to 20% is avoided while ensuring that the target BLER received by the VOLTE voice service reaches 1%, and the system utilization rate and the user experience are improved.
