Description

Technical Field

The embodiment of the invention relates to the technical field of mobile communication, in particular to a VOIP communication method and a VOIP communication device.

Background

With the large-scale use of Long Term Evolution (LTE) networks, Voice Over Internet Protocol (VOIP) communication is becoming more and more popular, and the call quality of VOIP service is also getting more and more attention from users. In practical application, the voice quality of VOIP is closely related to the packet loss rate and the transmission delay. The less the packet loss rate, the smaller the transmission delay, and the better the voice quality. However, demodulation performance of a Physical Uplink Control Channel (PUCCH) is poor, and in a relatively complex wireless environment, interference of the PUCCH is unbalanced, and demodulation may fail or be erroneous. At this time, the packet loss rate and the transmission delay will increase, reducing the voice call quality and affecting the user call experience.

Detailed Description

In order to make the objects, features and advantages of the present invention more obvious and understandable, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the embodiments described below are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The technical scheme of the embodiment of the invention can be applied to various communication systems, such as: a Global System for Mobile communications (GSM) System, a Code Division Multiple Access (CDMA) System, a Wideband Code Division Multiple Access (WCDMA) System, a General Packet Radio Service (GPRS), a long term evolution System, a LTE Frequency Division Duplex (FDD) System, a LTE Time Division Duplex (TDD), a Universal Mobile telecommunications System (WiMAX) or a Worldwide Interoperability Microwave Access (UMTS) communication System, etc.

The UE according to the embodiment of the present invention includes a Terminal (english: Terminal), a Mobile Station (MS), a Mobile Terminal (MS), or the like, and the UE may communicate with one or more core networks through a Radio Access Network (RAN), for example, the UE may be a Mobile phone (or a cellular phone) or a computer with a Mobile Terminal, for example, the UE may also be a portable, pocket, hand-held, computer-included, or vehicle-mounted Mobile device, and they exchange voice and/or data with the Radio Access Network.

The wireless access device provided in the embodiment of the present invention refers to a device for accessing a UE to a wireless network, and may be, for example, a Base Station (BTS) in GSM or CDMA, a Base Station (NodeB) in WCDMA, or an evolved Node B (eNB) in LTE.

The PUCCH is used to carry uplink control information, such as Hybrid Automatic Repeat reQuest (HARQ) feedback information, Scheduling ReQuest Indicator (SRI) for requesting uplink resource Scheduling, and the like. VOIP service is sensitive to packet loss rate and time delay, and for the problem of poor demodulation performance of PUCCH under the condition of high uplink interference, it is necessary to optimize transmission of uplink control information in the VOIP scenario to improve voice communication quality.

For example, in the conventional HARQ feedback mechanism, the feedback status is divided into three states of ACK, NACK, and DTX, where ACK indicates that demodulation of a Physical Downlink Shared Channel (PDSCH) is correct, NACK indicates that demodulation of the PDSCH is incorrect, and DTX indicates that Downlink Control Information (DCI) is lost. HARQ feedback of downlink data is mainly performed on PUCCH, but at the feedback time, if Uplink data needs to be sent on a Physical Uplink Shared Channel (PUSCH), the HARQ feedback may be transmitted on PUSCH. However, in the VOIP scenario, the uplink and downlink traffic are often staggered, and therefore, HARQ feedback is also transmitted through PUCCH. The PUCCH demodulation performance is poor, the probability that ACK may be misinterpreted as NACK or DTX is high in a complex wireless environment, and if ACK is misinterpreted, both packet loss rate and transmission delay may increase, which affects user conversation experience. Based on this, the embodiment of the invention actively triggers the PUSCH scheduling at the HARQ feedback time to feed back ACK or NACK on the PUSCH, and because the PUSCH demodulation performance is obviously superior to that of the PUCCH, the influence of poor PUCCH demodulation performance can be reduced, the probability of misinterpretation of HARQ feedback is reduced, and the user conversation experience is improved under a more complex wireless environment.

For another example, in a relatively complex wireless environment, PUCCH channel Interference is unbalanced, SINR (Signal to Interference plus Noise Ratio) bias of PUCCH format 1(format1) is low, SR (Scheduling Request) demodulation may fail, and SR is missed with high probability, so that a device (e.g., eNB) on the radio access network side cannot allocate uplink Grant (UP Grant) to the UE in time, thereby causing serious VOIP service packet loss and even a service single pass phenomenon, which affects user talk experience. Based on this, the embodiment of the invention actively triggers the PUSCH scheduling, and can still allocate uplink resources for the UE under the condition of SR missed detection, thereby reducing the influence of SR missed detection and improving the user conversation experience.

Therefore, the embodiment of the invention reduces the influence of poor demodulation performance of the PUCCH and improves the user conversation experience by actively triggering the dispatching of the PUSCH. The following description is made in conjunction with the accompanying drawings:

referring to fig. 1, fig. 1 is a flowchart illustrating a VOIP communication method according to a first embodiment of the present invention. The VOIP communication method described in this embodiment includes the following steps:

s101, the wireless access equipment determines the UE which is carrying out the VOIP service.

S102, monitoring scheduling of UE (user equipment) performing VOIP (voice over Internet protocol) service by wireless access equipment;

s103, the wireless access equipment actively carries out PUSCH scheduling on the UE to which the scheduling aims according to the monitored scheduling, and PUSCH resources are distributed to the UE;

s104, the wireless access equipment sends the allocated authorization of the PUSCH resource to the UE.

In this embodiment, the wireless access device finds the UE that is performing the VOIP service, and then determines whether to actively perform PUSCH scheduling on the UE according to the scheduling condition of the UE, so as to allocate PUSCH resources to the UE, so that HARQ feedback can be transmitted on the PUSCH, and the UE can still perform uplink transmission in the event of SR omission, thereby reducing the time delay caused by PUCCH demodulation failure or error, and improving the user experience.

VOIP traffic may include, but is not limited to: video service, voice service, or short message service. Determining whether the UE is engaged in a VOIP service may be determined by determining whether the UE is engaged in one or more of these services.

For example, in the LTE system, the determination of the VOIP service can be realized by QoS Class Identifier (QCI), where QoS is quality of service (QoS). Of the QCIs on Data Radio Bearer (DRB), QCIs 1, QCIs 2 and QCIs 5 are all voice-related QCIs. The QCI1 carries voice service, the QCI2 carries video service, and the QCI5 carries Session Initiation Protocol (SIP) signaling of the voice service, for example, SIP signaling used for establishing and releasing the voice service. When voice service is established, the SIP signaling is sent to the core network at the QCI5, the core network is triggered to establish a QCI1 bearer to complete the establishment of the voice service, or the establishment of the QCI1 bearer and the QCI2 bearer are needed for video telephone. When the voice service is ended, corresponding SIP signaling is transmitted on the QCI5 to trigger the core network to release the QCI1 for completion, or for the video telephone service, the QCI1 and the QCI2 need to be released for completion, and the call is considered to be ended. Therefore, whether the UE is carrying out the VOIP service or not is judged, and the starting and the ending can be judged through the SIP signaling of the QCI 5; may also be determined by the bearer of QCI 1.

In step S102, the wireless access device monitors scheduling of the UE performing the VOIP service, which may include monitoring of downlink scheduling of the UE and monitoring of uplink scheduling of the UE. Accordingly, in step S103, it may be determined whether to actively schedule the PUSCH for the UE according to a downlink scheduling or an uplink scheduling condition for the UE.

When the wireless access equipment monitors that downlink scheduling is performed on the UE, the wireless access equipment actively performs PUSCH scheduling on the UE to allocate PUSCH resources for the UE, wherein the PUSCH resources are used for feedback of the downlink scheduling, namely for the UE to send feedback of a downlink VOIP data packet for the downlink scheduling on the PUSCH resources.

And when the wireless access equipment monitors that uplink scheduling is not performed on the UE within the preset time span, actively performing PUSCH scheduling on the UE to allocate PUSCH resources for the UE, wherein the PUSCH resources are used for sending uplink VOIP data by the UE.

Both of these cases are described below in conjunction with fig. 2 and 6, respectively:

referring to fig. 2, fig. 2 is a flowchart illustrating a VOIP communication method according to a second embodiment of the present invention. The VOIP communication method described in this embodiment includes the following steps:

s201, the wireless access equipment determines the UE which is carrying out the VOIP service.

S202, the wireless access equipment monitors downlink scheduling of the UE.

And S203, when the wireless access device monitors that downlink scheduling is performed on the UE, actively performing PUSCH scheduling on the UE to allocate PUSCH resources for the UE, wherein the PUSCH resources are used for feedback of the downlink scheduling.

S204, the wireless access equipment sends the distributed authorization of the PUSCH resource to the UE.

The method for determining the UE performing the VOIP service is the same as the first embodiment, and is not described herein again.

HARQ uses a stop-and-wait protocol (english) to transmit data. In the stop-wait protocol, after the sending end sends data, the sending end needs to stop waiting for the feedback of the receiving end, and can determine whether to send a new packet or a retransmission packet next time after receiving the feedback. If the feedback is stopped after each information transmission, the resource waste and the low throughput are caused, and therefore, the concept of the HARQ process is introduced. While one HARQ process is waiting for feedback, the transmitting end may continue to transmit data using another HARQ process. Each Transmission Time Interval (abbreviated as TTI) corresponds to only one HARQ process number, and considering a reasonable upper limit of processing delay, for each HARQ process, a difference between each scheduling Time and a feedback Time for the scheduling is a fixed TTI. Therefore, when the wireless access equipment performs downlink scheduling on the UE, the feedback time of the downlink scheduling can be determined. For example, if the grant time of the radio access equipment to the downlink scheduling is T1, the feedback time of the downlink scheduling is T1+ K1, where K1 is the feedback delay from the grant of the downlink scheduling to the feedback of the downlink scheduling, and may also be understood as the time interval between the HARQ feedback of the downlink transmission and the downlink transmission. The individual time points described here, for example, grant time points, feedback time points, and the like can be reflected by subframe numbers, and the unit of K1 is TTI.

In a Frequency Division Duplex (FDD) communication system, K1 takes the value 4. In a Time Division Duplex (TDD) communication system, the value of K1 is determined according to the uplink and downlink subframe ratio and the HARQ feedback timing of each uplink and downlink subframe ratio. Specifically, see the Table in 3GPP standard 36.213, Table 10.1.3.1-1, which is shown in the HARQ feedback timing of TDD in Table 1 below:

TABLE 1

The first column in table 1 is the serial numbers of different uplink and downlink allocations in the TDD system, and as shown in table 2, there are frame structures of various uplink and downlink allocations in the TDD system. Each frame comprises 10 subframes which are respectively represented by numbers 0-9, and a subframe for downlink transmission in each frame structure is represented by D, a subframe for uplink transmission is represented by U, S represents a special subframe and is used for switching between uplink and downlink subframes.

As can be seen from table 2, in the TDD system, there are many downlink subframes and few uplink subframes, and it is impossible to perform HARQ feedback by using one uplink subframe corresponding to each downlink subframe. Therefore, HARQ feedback of all the nth-k downlink subframes is performed on the nth uplink subframe, where n is the subframe number and the value of k can be obtained from table 1. Please refer to the HARQ feedback timing diagrams of ratio 0 to ratio 2 shown in fig. 3 to 5. For the ratio 0, the subframe 2 is used for performing uplink feedback on downlink transmission of the previous 6 subframes, at this time, the value of K is 6, and the corresponding value of K1 is 6; subframe 4 is used to perform uplink feedback on downlink transmissions of the previous 4 subframes, where K is 4 and the corresponding K1 is 4. Other proportions are similar and will not be described in detail herein.

TABLE 2

The above principle can also be expressed by the following formula (1):

DL_Voip_SchStatus(CurrentTti-K1)＝TRUE (1)

wherein: in formula (1), CurrentTti represents the current time, DL _ Voip _ schstatus (x) represents whether downlink scheduling is performed on the UE at time x, and the meaning and value of K1 are the same as above, which are not described herein again. If downlink scheduling is performed on the UE, the value of DL _ Voip _ SchStatus is TRUE, and then PUSCH scheduling needs to be actively performed on the UE at the current moment; if downlink scheduling is not performed on the UE, the value of DL _ Voip _ SchStatus is FALSE, and active scheduling of PUSCH on the UE is not required at the current moment.

After the UE is scheduled with the PUSCH, the UE needs to be notified of the PUSCH resource allocated to the UE, that is, the UE is sent with the grant of the PUSCH resource. The grant is sent prior to HARQ feedback by the UE to inform the UE on which PUSCH resources to feedback. If the grant time of the downlink scheduling is T, the feedback time of the UE is T + K1, and the transmission time of the grant of the PUSCH resource, that is, the grant time of the PUSCH resource (which may also be referred to as the grant time of the uplink scheduling) is T + K1-K2, where K2 is the transmission delay from the grant of the PUSCH resource to the PUSCH transmission.

Currently, a base station sends an uplink grant to a UE through a Physical Downlink Control Channel (PDCCH), and the UE obtains the uplink grant by detecting the PDCCH and further performs PUSCH transmission according to the uplink grant. In FDD systems, the delay between grant on PDCCH to PUSCH transmission is 4 TTI. In the TDD system, since each subframe is fixedly used for uplink transmission or downlink transmission in each frame structure, after a subframe (e.g., a downlink subframe or a special subframe) used for downlink transmission detects an uplink grant, the UE needs to wait until the subframe (e.g., the uplink subframe or the special subframe) used for uplink transmission to perform PUSCH transmission, so that in the TDD system, a time delay from grant on a PDCCH to PUSCH transmission is related to a ratio of uplink subframes to downlink subframes, and a PUSCH transmission timing sequence for each ratio of uplink subframes to downlink subframes is given in table 3. Therefore, in an FDD communication system, the value of K2 is 4, and in a TDD communication system, the value of K2 is determined according to the uplink and downlink subframe allocation and the PUSCH transmission timing of each uplink and downlink subframe allocation. Specifically, see the Table in 3GPP standard 36.213, Table 8-2, which is shown in the PUSCH transmission timing of TDD in Table 3 below:

TABLE 3

As can be seen from table 3, for ratio 2, subframe 3 is used to authorize PUSCH transmission for the following 4 subframes, and the value of K2 is 4 at this time; subframe 8 is used to grant PUSCH transmission for the following 4 subframes, where K2 takes a value of 4. Other proportions are similar and will not be described in detail herein.

At this time, the above formula (1) may be further optimized as the following formula (2)

DL_Voip_SchStatus(CurrentTti-K1+K2)＝TRUE (2)

Wherein: in formula (2), CurrentTti represents the current time, DL _ Voip _ schstatus (x) represents whether downlink scheduling is performed on the UE at time x, and the meanings and values of K1 and K2 are the same as above, and are not described herein again. If downlink scheduling is performed on the UE, the value of DL _ Voip _ SchStatus is TRUE, and then PUSCH scheduling needs to be actively performed on the UE at the current moment; if downlink scheduling is not performed on the UE, the value of DL _ Voip _ SchStatus is FALSE, and active scheduling of PUSCH on the UE is not required at the current moment.

In this embodiment, the wireless access device monitors the UE that is performing the VOIP service, and when it is monitored that downlink scheduling is performed on the UE, actively initiates PUSCH scheduling on the UE to allocate uplink resources to the UE, so that the UE performs feedback of the downlink scheduling by using the allocated uplink resources. Therefore, the feedback information can be transmitted on the PUSCH, and compared with the PUCCH, the PUSCH has higher transmitting power and better demodulation performance, thereby greatly reducing the probability of demodulation failure or error and improving the quality of voice call.

Referring to fig. 6, fig. 6 is a flowchart illustrating a communication method of a VOIP service according to a third embodiment of the present invention. The method described in this embodiment includes the following steps:

s601, the wireless access equipment determines the UE which is carrying out the VOIP service.

S602, the wireless access equipment monitors the uplink scheduling of the UE.

S603, when the wireless access equipment does not perform uplink scheduling on the UE within a preset time length, actively performing PUSCH scheduling on the UE to allocate PUSCH resources for the UE, wherein the PUSCH resources are used for sending uplink VOIP data by the UE.

S604, the wireless access equipment sends the allocated authorization of the PUSCH resource to the UE.

When the UE performs VOIP service, it can be in one of the following two states:

(1) and a call state: mainly refers to the state of the UE when the user of the UE is speaking, and in the call state, a data packet is usually generated every 20ms, and hereinafter, the period in which the UE generates the data packet in the call state is referred to as a first period.

(2) Silent state: mainly refers to the state of the UE when the user of the UE is listening, and in the silent state, a data packet is usually generated every 160ms, and hereinafter, the period during which the UE generates the data packet in the silent state is referred to as a second period.

No matter what state the UE is, in the VOIP scenario, the wireless access device should receive the uplink data packet of the UE within a certain time period. If the uplink data packet of the UE cannot be received, possibly because the PUCCH of the UE is demodulated incorrectly or fails, the radio access network device cannot obtain the SR of the UE, and thus cannot perform uplink scheduling on the UE. In this embodiment, the SR of the UE is not used as a basis, and PUSCH scheduling is actively performed on the UE to allocate uplink resources to the UE, so that the UE sends an uplink VOIP data packet. In an extreme case, of course, there is no uplink packet generated by any party of the call, but the overall improvement of the voice call quality is not affected.

The above principle can also be expressed by the following formula (3):

(CurrentTTI-LastPreAllocationTime)＞＝PreAllocationMinPeriodicity (3)

wherein, CurrentTTI represents a current time, lastpreallocation time represents a last uplink scheduling time closest to the current time, and preallocation minimum periodicity represents a preset time length. When the above equation (3) is established, PUSCH scheduling is actively initiated for the UE.

With respect to the preset time length, those skilled in the art can set it as desired. The present invention is not limited by the embodiments, and an exemplary setting is given below, as shown in formula (4), which is only for example and is not intended to limit the present invention.

(ii) preallocation min periodicity (UE in talk state? Period 0: second periodicity),

period0 ═ t? t (SR Period: first Period) (4)

In equation (4), the first and second periods have the same meaning as described above, i.e. the periods for generating data packets when the UE is in the talk state and the silence state, respectively, usually the second period is greater than the first period. t is a preset time length value between the first period and the second period.

As can be seen from the formula (4), when the UE is in the call state, the value of the preset time duration preallocation minimum periodicity is Period 0; when the UE is not in the call state, i.e., in the silence state, the value of the preset time duration preallocation minimum periodicity is the second period. The value of Period0 is related to the SR cycle, when the SR cycle is greater than or equal to the preset value t, the value of Period0 is t; when the SR Period is less than the preset value t, the value of Period0 is the first Period.

In this embodiment, the wireless access device monitors the UE performing the VOIP service, and when it is monitored that the uplink scheduling is not performed on the UE within the preset time period, the wireless access device does not actively perform PUSCH scheduling on the UE according to the decoded SR any more, so as to allocate uplink resources to the UE, so that the UE can transmit uplink VOIP data using the uplink resources. Therefore, under the condition that the SR is missed, the UE can still carry out uplink transmission so as to reduce time delay caused by failure or error of PUCCH demodulation and improve the conversation experience of a user.

Referring to fig. 7, fig. 7 is a flowchart illustrating a VOIP communication method according to a fourth embodiment of the present invention. The VOIP communication method described in this embodiment includes the following steps:

s701, UE receives authorization of PUSCH resources allocated to the UE by wireless access equipment, wherein VOIP business is carried out between the UE and the wireless access equipment, and the PUSCH resources are actively allocated to the UE by the wireless access equipment according to monitoring of scheduling of the UE.

S702, the UE determines the PUSCH resource according to the authorization.

And S703, the UE performs uplink transmission on the determined PUSCH resource.

Optionally, the PUSCH resource is a resource actively allocated to the UE by the wireless access device for feedback of the downlink scheduling when monitoring that the downlink scheduling is performed on the UE.

Further optionally, the grant time of the downlink scheduling is T, and the feedback time of the downlink scheduling is T + K1, where K1 is a feedback delay from the grant of the downlink scheduling to the feedback of the downlink scheduling.

It should be noted that, in the FDD communication system, the value of K1 is 4, and in the TDD communication system, the value of K1 is determined according to the uplink and downlink subframe allocation and the HARQ feedback timing of each uplink and downlink subframe allocation.

Further, the grant time of the PUSCH resource is T + K1-K2, where K2 is the transmission delay from the grant of the PUSCH resource to the PUSCH transmission.

It should be further noted that, in an FDD communication system, the value of K2 is 4, and in a TDD communication system, the value of K2 is determined according to the uplink and downlink subframe allocation and the PUSCH transmission timing of each uplink and downlink subframe allocation.

Correspondingly, the PUSCH resource is a resource actively allocated to the UE by the wireless access device for sending uplink VOIP data to the UE when it is monitored that the uplink scheduling is not performed on the UE within a preset time period.

Optionally, when the UE is in a call state, the preset time duration is a first time duration; when the UE is in the silent state, the preset time duration is a second time duration, and the first time duration is smaller than the second time duration.

As can be seen from the above, in this embodiment, the UE receives the authorization of the PUSCH resource allocated to the UE by the wireless access device, determines the PUSCH resource according to the authorization, and performs uplink transmission on the determined PUSCH resource, where the VOIP service is being performed between the UE and the wireless access device, and the PUSCH resource is actively allocated to the UE by the wireless access device according to the monitoring of the scheduling of the UE. Therefore, HARQ feedback can be transmitted on the PUSCH, and under the condition that SR is missed, the UE can still perform uplink transmission, so that time delay caused by PUCCH demodulation failure or error is reduced, and the user conversation experience is improved.
