Description

Resource scheduling method and device

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a resource scheduling method and apparatus.

Background

A Long Term Evolution (LTE) network is an Internet Protocol (IP) network, and therefore, a voice service is carried in a voice over internet protocol (VoIP) manner, and VoIP is a technology capable of transmitting analog audio or video over an IP network, and its basic principle is as follows: performing voice compression coding processing on voice data through a voice compression algorithm, then packaging the processed data according to related protocols such as IP (Internet protocol), and transmitting a data packet to a receiving end through an IP network; the receiving end concatenates the received data packets, and restores the received data packets into original voice signals after decoding and decompression processing, thereby achieving the purpose of transmitting voice through the IP network.

According to The third generation partnership project (The 3)^rd3 GPP) protocol, Semi-Persistent Scheduling (SPS) can be applied to VoIP, which is a service resource allocation with stable packet size and packet transmission interval, and a specific VoIP service source model is shown in fig. 1. The existing SPS scheduling scheme is for voice service with coding rate of 12.2kbps, when the service is detected to enterDuring an activation period, sending an SPS resource activation instruction through a Physical Downlink Control Channel (PDCCH), wherein initial transmission data of a VoIP service is transmitted by using allocated SPS semi-persistent resources during the activation period of the VoIP service, retransmission data packets are transmitted by using a dynamically scheduled resource allocation mode, and the allocated SPS semi-persistent resources are not changed during the activation period of the VoIP service; when detecting that the service enters the silent period, the SPS resource is deactivated in an explicit (namely PDCCH indication) or implicit mode, and the data packet of the VoIP service silent period is transmitted in a resource allocation mode of dynamic scheduling.

In the existing SPS scheduling scheme, SPS resources configured by the network side for the terminal are not changed during the active period of the VoIP service. During the activation period, if the uplink and downlink channels of the terminal change, the user experience will be reduced if the resources used by the terminal are not adjusted in time. If the channel condition of the current terminal is better than the channel quality when the SPS resources are activated, at the moment, the SPS semi-continuous resources required for transmitting the effective data are less, if the resources used by the terminal are not adjusted in time, the waste of the resources is caused, the system can not access more users, and the user experience is reduced; for another example, when the channel condition of the terminal is worse than that when the SPS resource is activated, at this time, the SPS semi-persistent resource required for transmitting valid data needs to be increased, and if the resource used by the terminal is not adjusted in time, the probability of data transmission error is increased, the transmission delay is increased, and the user experience is reduced.

In summary, in the existing SPS scheduling scheme, if an uplink/downlink channel of a terminal changes during an active period of a VoIP service, a problem of user experience degradation may be caused.

The embodiments of the present invention will be described in further detail with reference to the drawings attached hereto. It is to be understood that the embodiments described herein are merely illustrative and explanatory of the invention and are not restrictive thereof.

Referring to fig. 2, a method for scheduling resources according to an embodiment of the present invention includes:

step 21, for each terminal transmitting the VoIP service, after the SPS resource used by the terminal for transmitting the VoIP service is activated, in each set adjustment period, acquiring the channel quality information of the terminal and/or information related to data transmission of the terminal.

In this step, the information related to the data transmission of the terminal includes, but is not limited to, at least one of the following information:

a Block Error Rate (BLER) of a bearer for transmitting VoIP traffic of the terminal;

data transmission spectrum efficiency for transmitting the bearer of the VoIP service of the terminal;

and the effective data transmission ratio of the terminal, wherein the effective data transmission ratio is used for indicating the proportion of the effective VoIP data carried in the data packet correctly received by the terminal to the total received data.

And step 22, after each set adjustment period is finished for each terminal transmitting the VoIP service, judging whether to adjust SPS resources used by the terminal according to the channel quality information of the terminal and/or information related to data transmission of the terminal.

In this step, the embodiment of the present invention may not perform the determination process at any time after the end of the set adjustment period.

And step 23, if the SPS resource used by the terminal needs to be adjusted is judged to be needed for each terminal transmitting the VoIP service, the SPS resource used by the terminal is adjusted, and the adjusted SPS resource is notified to the terminal.

In implementation, the main execution body of the method is a base station, and may also be other network entities.

The method provided by the embodiment of the invention can flexibly adjust the SPS resources used by the terminal in the activation period of the SPS resources allocated by the terminal, thereby improving the user experience and increasing the user capacity.

In implementation, as a preferred implementation manner, step 21 is specifically: for each terminal transmitting VoIP service, after SPS resources used by the terminal for transmitting the VoIP service are activated, starting a timer for adjusting the SPS resources, and acquiring channel quality information of the terminal and/or information related to data transmission of the terminal during the timing period of the timer;

correspondingly, step 22 specifically includes: and for each terminal transmitting the VoIP service, when the timer times out, judging whether the SPS resources used by the terminal need to be adjusted according to the acquired channel quality information of the terminal and/or the information related to the data transmission of the terminal.

In this preferred mode, the method further includes: and after judging that the SPS resources used by the terminal do not need to be adjusted or the adjustment of the SPS resources used by the terminal is completed, starting the timer again, and acquiring the channel quality information of the terminal and/or the information related to the data transmission of the terminal during the timing period of the timer.

The embodiment of the present invention is not limited to adopt the above preferred implementation manner, and step 21 and step 22 may also be realized in other manners, for example, step 21 specifically includes: for each terminal transmitting the VoIP service, starting from the activation time of the SPS resource after the last adjustment (if the current is the first adjustment, the SPS resource is activated for the first time), acquiring the channel quality information of the terminal and/or the information related to the data transmission of the terminal; correspondingly, step 22 specifically includes: and for each terminal transmitting the VoIP service, after the difference value between the current time and the activation time of the SPS resource which is adjusted last time by the terminal is larger than the set timestamp, judging whether the SPS resource used by the terminal needs to be adjusted according to the acquired channel quality information of the terminal and/or the information related to the data transmission of the terminal.

In implementation, in step 22, according to the channel quality information of the terminal and/or information related to data transmission of the terminal, it is determined whether SPS resources used by the terminal need to be adjusted, which specifically includes the following ways:

mode 1, only according to the channel quality information of the terminal, judge whether need to adjust the SPS resource that the terminal uses.

In this manner, step 21 specifically includes: for each terminal transmitting the VoIP service, in each set adjustment period, a Modulation and Coding Scheme (MCS) level (index) corresponding to Channel Quality Indicator (CQI) information reported by the terminal is obtained.

Correspondingly, step 22 specifically includes: after each adjustment period is finished for each terminal transmitting the VoIP service, whether the SPS resource used by the terminal needs to be adjusted is determined according to the obtained MCS level (marked as MCS _ index _ New) and the MCS level (marked as MCS _ index) of the SPS resource allocated by the terminal.

Further, according to the obtained MCS level and the MCS level of the SPS resource allocated to the terminal, determining whether the SPS resource used by the terminal needs to be adjusted, specifically including:

when the absolute value of the difference value between the obtained MCS level and the MCS level of the SPS resource allocated to the terminal is not greater than the set offset, judging that the SPS resource used by the terminal does not need to be adjusted;

or when the absolute value of the difference between the obtained MCS level and the MCS level of the SPS resource allocated to the terminal is greater than the offset, determining that the SPS resource used by the terminal needs to be adjusted.

In this manner, in step 23, when it is determined that the SPS resource used by the terminal needs to be adjusted, the adjusting the SPS resource used by the terminal specifically includes:

when the difference value obtained by subtracting the MCS level of the SPS Resource allocated by the terminal from the obtained MCS level is larger than the set offset, determining to reduce the number of Physical Resource Blocks (PRBs) allocated by the SPS Resource used by the terminal; or,

and when the difference value obtained by subtracting the obtained MCS level from the MCS level of the SPS resource allocated by the terminal is larger than the set offset, determining to increase the number of PRBs allocated to the SPS resource used by the terminal.

For example, it is assumed that the MCS level corresponding to the CQI reported by the terminal acquired in the adjustment period is MCS _ Index _ New; the MCS level of the SPS resource allocated to the terminal is MCS _ Index, and whether the SPS resource used by the terminal needs to be adjusted is determined as follows:

if abs (MCS _ Index _ New-MCS _ Index) is less than alfa _1, that is, the MCS level does not change much, then no operation is performed, that is, there is no need to adjust the SPS resource used by the terminal;

otherwise, if MCS _ Index _ New > MCS _ Index + alfa _1, it indicates that the number of PRBs allocated by SPS resources can be reduced; if MCS _ Index _ New < MCS _ Index-alfa _1, it indicates that the number of PRBs for SPS resource allocation needs to be increased.

In this manner, in step 23, notifying the adjusted SPS resource to the terminal includes: the adjusted SPS resource is indicated again by the content of UL grant (uplink scheduling) or DL assignment (downlink configuration) of "PDCCH with SPS-CRNTI NDI = 0", and the adjusted SPS resource and the obtained MCS level (i.e., MCS _ Index _ New) are carried in the UL grant or the DL assignment. Wherein, the PDCCH is an abbreviation of a Physical downlink control Channel (Physical downlink control Channel); the SPS-CRNTI is an abbreviation of Semi-Persistent Scheduling-CRNTI (SPS-CRNTI; Cell-Radio Network temporary identifier, C-RNTI); NDI is an abbreviation for New Data Indicator (New Data Indicator).

In this way, the CQI information reported by the terminal and acquired in the adjustment period may be a filtered smoothed value of at least one piece of CQI information in the adjustment period, or may be the CQI information reported the latest time from the arrival time of the adjustment period; preferably, the CQI reported by the terminal and acquired in the adjustment period may be a corrected value, and the correction influence on the SPS resource is not considered.

Mode 2, whether the SPS resource used by the terminal needs to be adjusted is determined only according to one of the information related to the data transmission of the terminal.

In this manner, step 22 specifically includes: and after each adjustment period is finished for each terminal transmitting the VoIP service, judging whether the SPS resources used by the terminal need to be adjusted or not according to the information related to the terminal data transmission acquired in the adjustment period and the information related to the terminal data transmission acquired in the last adjustment period.

Further, determining whether to adjust SPS resources used by the terminal according to the information related to terminal data transmission acquired in the adjustment period and the information related to terminal data transmission acquired in the previous adjustment period, includes:

judging that SPS resources used by the terminal do not need to be adjusted when the absolute value of the difference value between the information related to terminal data transmission acquired in the adjustment period and the information related to terminal data transmission acquired in the last adjustment period is not greater than the threshold corresponding to the information related to terminal data transmission;

or,

and when the absolute value of the difference value between the information related to the terminal data transmission acquired in the adjustment period and the information related to the terminal data transmission acquired in the last adjustment period is greater than the threshold value corresponding to the information related to the terminal data transmission, judging that the SPS resource used by the terminal needs to be adjusted.

In an implementation, the method further comprises:

in the mode 2a, the information related to the data transmission of the terminal is the BLER of the bearer used for transmitting the VoIP service of the terminal.

In this manner, step 22 specifically includes: and for each terminal transmitting the VoIP service, after each adjustment period is finished, judging whether SPS resources used by the terminal need to be adjusted or not according to the BLER obtained in the adjustment period and the BLER obtained in the last adjustment period.

Further, when the absolute value of the difference between the BLER obtained in the present adjustment period and the BLER obtained in the previous adjustment period is not greater than the threshold corresponding to the set BLER, it is determined that SPS resources used by the terminal do not need to be adjusted; or,

and when the absolute value of the difference value between the BLER acquired in the adjusting period and the BLER acquired in the last adjusting period is larger than the threshold corresponding to the set BLER, judging that the SPS resource used by the terminal needs to be adjusted.

Further, in step 23, when it is determined that the SPS resource used by the terminal needs to be adjusted, adjusting the SPS resource used by the terminal includes:

when the difference value obtained by subtracting the BLER obtained in the last adjustment period from the BLER obtained in the adjustment period is larger than the threshold value corresponding to the set BLER, determining to increase the number of PRBs allocated to SPS resources used by the terminal and adjusting the MCS level of the SPS resources used by the terminal at present; or,

and when the difference value obtained by subtracting the BLER obtained in the previous adjustment period from the BLER obtained in the previous adjustment period is larger than the threshold corresponding to the set BLER, determining the number of PRBs for reducing the SPS resource allocation used by the terminal and increasing the MCS level of the SPS resource currently used by the terminal.

For example, suppose that BLER of data transmission carried by the VoIP service obtained in the current adjustment period is BLER _ New, BLER of data transmission carried by the VoIP service obtained in the last adjustment period is BLER:

if the absolute value abs (BLER _ New-BLER) is less than or equal to alfa _2, namely the difference between the BLERs counted in the two adjustment periods is not large, no operation is performed;

otherwise, if BLER _ New > BLER + alfa _2, it indicates that the MSC level corresponding to the currently used SPS resource is too high, and needs to be adjusted downwards, and meanwhile, the number of PRBs allocated by the SPS resource needs to be increased; if BLER _ New < BLER-alfa _2, it indicates that the MSC level corresponding to the SPS resource currently used is too low, and needs to be adjusted upwards, and meanwhile, the number of PRBs allocated to the SPS resource can be reduced.

In this manner, preferably, the BLER obtained in the adjustment period is an average value of at least one BLER in the adjustment period.

In this way, the threshold corresponding to the BLER is a value greater than or equal to 0, the specific value precision depends on the statistical BLER precision and the residual BLER requirement of the VoIP service, and needs to be smaller than the residual BLER requirement of the VoIP service, and the preliminary suggestion may be in the order of 10-e 3.

It should be noted that, only data transmission BLER carried by the VoIP service under the currently allocated SPS resource is counted in the first adjustment period after the SPS resource of the terminal is activated, and no adjustment processing is performed; after each subsequent adjusting period is finished, comparing and judging the statistical result in the adjusting period with the statistical result in the previous adjusting period.

In this manner, in step 23, notifying the adjusted SPS resource to the terminal includes: and indicating the adjusted SPS resource again through the content of UL grant (uplink scheduling) or DL assignment (downlink configuration) of the PDCCH with SPS-CRNTI NDI =0, wherein the adjusted SPS resource and the adjusted MCS level are carried in the UL grant or the DL assignment.

In the mode 2b, the information related to the terminal data transmission is the data transmission spectrum efficiency of the bearer for transmitting the VoIP service of the terminal.

In this manner, step 22 specifically includes: and for each terminal transmitting the VoIP service, after each adjustment period is finished, judging whether the SPS resources used by the terminal need to be adjusted or not according to the spectral efficiency obtained in the adjustment period and the spectral efficiency obtained in the last adjustment period.

Further, when the absolute value of the difference between the spectral efficiency of data transmission acquired in the adjustment period and the spectral efficiency acquired in the previous adjustment period is not greater than the threshold corresponding to the spectral efficiency, it is determined that SPS resources used by the terminal do not need to be adjusted; or,

and when the absolute value of the difference value between the spectrum efficiency acquired in the adjustment period and the spectrum efficiency acquired in the last adjustment period is greater than the threshold corresponding to the spectrum efficiency, judging that the SPS resource used by the terminal needs to be adjusted.

For example, assuming that the data transmission spectrum efficiency of the VoIP service bearer acquired in the current adjustment period is eff _ New, and the data transmission spectrum efficiency of the VoIP service bearer acquired in the previous adjustment period is eff, then:

if the absolute value abs (eff _ New-eff) < alfa _3, that is, the spectral efficiency of data transmission counted by two adjustment periods is not very different, then do nothing;

otherwise, if eff _ New > eff + alfa _3, it is indicated that the grade of the MSC corresponding to the currently used SPS resource is too low, and it is necessary to perform up-regulation, and at the same time, it is necessary to reduce the number of PRBs allocated to the SPS resource; if eff _ New < eff-alfa _3, it indicates that the MSC level corresponding to the currently used SPS resource is too high, and needs to be adjusted downward, and at the same time, the number of PRBs allocated to the SPS resource may be increased.

In this manner, preferably, the spectral efficiency obtained in the adjustment period is an average value of results of at least one statistical spectral efficiency in the adjustment period.

It should be noted that, only the data transmission spectrum efficiency of the VoIP service bearer under the currently allocated SPS resource is counted in the first adjustment period after the SPS resource of the terminal is activated, and no adjustment processing is performed; after each subsequent adjusting period is finished, comparing and judging the statistical result in the adjusting period with the statistical result in the previous adjusting period.

In this way, the threshold corresponding to the spectral efficiency is a value greater than or equal to 0, the specific value precision depends on the precision of the statistical spectral efficiency and the precision requirement of the spectral efficiency expected by the VoIP service, and needs to be less than the precision of the spectral efficiency expected by the VoIP service, and the preliminary suggestion may be in the order of 10-e 3.

Mode 2c, the information related to terminal data transmission is an effective data transmission ratio of the terminal, where the effective data transmission ratio is used to indicate a ratio of effective VoIP data carried in a data packet correctly received by the terminal to received total data, that is, the number of effective VoIP data bits carried in the correctly received data packet is divided by the number of bits of the data packet (that is, transport block size (TB size)).

In this manner, step 22 specifically includes: and for each terminal transmitting the VoIP service, after each adjustment period is finished, judging whether the SPS resources used by the terminal need to be adjusted or not according to the effective data transmission rate acquired in the adjustment period and the effective data transmission rate acquired in the last adjustment period.

Further, when the absolute value of the difference between the effective data transmission rate obtained in the adjustment period and the effective data transmission rate obtained in the previous adjustment period is not greater than the threshold corresponding to the set effective data transmission rate, it is determined that the SPS resource used by the terminal does not need to be adjusted; or,

and when the absolute value of the difference value between the effective data transmission rate acquired in the adjustment period and the effective data transmission rate acquired in the last adjustment period is greater than the threshold corresponding to the set effective data transmission rate, judging that the SPS resource used by the terminal needs to be adjusted.

when the difference value obtained by subtracting the effective data transmission rate obtained in the last adjustment period from the effective data transmission rate obtained in the adjustment period is larger than the threshold corresponding to the set effective data transmission rate, determining to reduce the number of PRBs allocated to the SPS resources used by the terminal and increasing the MCS level of the SPS resources currently used by the terminal; or,

For example, assuming that the effective data transmission ratio of the VoIP service bearer acquired in the current adjustment period is ratio _ New, and the effective data transmission ratio of the VoIP service bearer acquired in the previous adjustment period is ratio, then:

if the absolute value abs (ratio _ New-ratio) is less than or equal to alfa _4, that is, the effective data transmission ratios of the two adjustment period statistics are not different, then do nothing;

otherwise, if ratio _ New > ratio + alfa _4, it indicates that the MSC level corresponding to the currently used SPS resource is too high, and needs to be adjusted downward, and at the same time, needs to increase the number of PRBs allocated to the SPS resource; if the ratio _ New < ratio-alfa _4 indicates that the MSC level corresponding to the currently used SPS resource is too low, the MSC level needs to be adjusted upwards, and meanwhile, the number of PRBs allocated to the SPS resource can be reduced.

In this manner, the effective data transmission rate obtained in the adjustment period is preferably an average value of results of at least one effective data transmission rate counted in the adjustment period.

It should be noted that, only the effective data transmission rate of the VoIP service bearer under the currently allocated SPS resource is counted in the first adjustment period after the SPS resource of the terminal is activated, and no adjustment is performed; after each subsequent adjusting period is finished, comparing and judging the statistical result in the adjusting period with the statistical result in the previous adjusting period.

In this way, the threshold corresponding to the effective data transmission ratio is a value greater than or equal to 0, the specific value precision depends on the precision of the statistical effective data transmission ratio, and the preliminary suggestion may be in the order of 10-e 3.

Mode 3, determining whether to adjust SPS resources used by the terminal according to at least one of channel quality information of the terminal and information related to data transmission of the terminal.

In this manner, it is determined whether SPS resources used by the terminal need to be adjusted according to the channel quality information of the terminal, which is specifically described in the manner 1 and is not described herein again; for determining whether the SPS resource used by the terminal needs to be adjusted according to at least one of the information related to data transmission of the terminal, refer to the above description of the mode 2a to the mode 2c, which is not described herein again.

In this manner, if the determination result obtained from the channel quality information of the terminal is different from the determination result obtained from the information related to the data transmission of the terminal, the determination result obtained from the channel quality information of the terminal is taken as the final determination result. Namely: when the determination result conflicts, the priority of the determination result obtained from the channel quality information of the terminal is higher than the determination result obtained from the information related to the data transmission of the terminal.

And 4, judging whether the SPS resources used by the terminal need to be adjusted according to at least two kinds of information in the information related to the data transmission of the terminal.

In this manner, whether the SPS resource used by the terminal needs to be adjusted is determined according to at least one of the information related to data transmission of the terminal, which is specifically described in the foregoing reference to the descriptions of the manner 2a to the manner 2c, and is not described herein again.

In this way, if the determination result obtained according to the BLER of the bearer for transmitting the VoIP service of the terminal is different from the determination result according to the data transmission spectrum efficiency of the bearer for transmitting the VoIP service of the terminal and/or the determination result according to the effective data transmission ratio of the terminal, the determination result obtained according to the BLER of the bearer for transmitting the VoIP service of the terminal is used as a final determination result;

and if the judgment result of the data transmission spectrum efficiency according to the load of the VoIP service for transmitting the terminal is different from the judgment result of the effective data transmission ratio according to the terminal, taking the judgment result of the data transmission spectrum efficiency according to the load of the VoIP service for transmitting the terminal as a final judgment result.

In this mode, when a conflict occurs in the determination results, the determination result obtained in the mode 2a has a higher priority than the determination result obtained in the mode 2b, and the determination result obtained in the mode 2b has a higher priority than the determination result obtained in the mode 2 c.

Based on any of the above embodiments, in step 23, when it is determined that the SPS resource used by the terminal needs to be adjusted, adjusting the SPS resource used by the terminal includes:

and when determining that the SPS resources used by the terminal need to be adjusted, adjusting the SPS resources used by the terminal according to the voice coding rate of the VoIP service transmitted by the terminal.

In practice, the method further comprises: and determining SPS resources initially used by the terminal for transmitting the VoIP service according to the voice coding rate of the VoIP service transmitted by the terminal. That is, when SPS resources are initially allocated to a terminal, the SPS resources also need to be allocated to the terminal according to the voice coding rate of the VoIP service transmitted by the terminal.

Based on any embodiment, the voice coding rate of the VoIP service transmitted by the terminal is determined according to the following method:

in the first mode, the speech coding Rate of the VoIP service transmitted by the terminal is determined according to a Maximum Bit Rate (MBR) parameter corresponding to a bearer used for transmitting the VoIP service of the terminal.

In this way, the MBR parameter configured by the VoIP service bearer is directly judged. The method specifically comprises the following steps:

if the MBR is Adaptive Multi-rate-Wideband (AMR-WB) 23.85kbps, determining that the current VoIP service bearing coding mode of the terminal is AMR-WB;

and if the MBR is Adaptive Multi-rate-Narrow Band (AMR-NB) 12.2kbps, determining that the current VoIP service bearer coding mode of the terminal is AMR-NB.

And secondly, determining the voice coding rate of the VoIP service transmitted by the terminal according to the monitored size of the data packet of the uplink VoIP service and/or the downlink VoIP service of the terminal.

In this way, the detected data packets of the uplink VoIP service (i.e., the VoIP service transmitted by the terminal uplink) and the downlink VoIP service (i.e., the VoIP service transmitted to the terminal downlink for reception) may be counted together, or the data packets of the uplink VoIP service and the downlink VoIP service may be counted separately (i.e., counted separately in both uplink and downlink directions). For the way of separately counting two directions, as long as one direction determines the coding rate, the other direction also determines the same coding rate, that is, after the coding rate is determined, the counting process in the two directions can be stopped at the same time.

In the mode, in a set monitoring period (VoIPAMRModeCheckTime), when the size (size) of a monitored data packet of an uplink VoIP service and/or a downlink VoIP service of a terminal is smaller than a set threshold value, a first counter for counting AMR-NB is increased by 1; and/or when the monitored size of the data packet of the uplink VoIP service and/or the downlink VoIP service of the terminal is not smaller than the threshold value, adding 1 to a second counter for counting AMR-WB;

Further, if the value of the first counter is smaller than the set threshold and the value of the second counter is smaller than the set threshold in the monitoring period, after the monitoring period is ended, the voice coding rate of the VoIP service transmitted by the terminal is determined according to the value of the first counter and the value of the second counter.

Specifically, if the value of the first counter is greater than the value of the second counter, the voice coding rate of the VoIP service transmitted by the terminal is determined to be AMR-NB; or,

For example, a VoIP service bearer coding rate recognition timer, VoIPAMRModeCheckTime, is started, and n1 detected AMR-NB packets (i.e., a first counter) and n2 detected AMR-WB packets (i.e., a second counter) are respectively initialized. Recording the size of the data packet received in the VoIP activation period as VoIP _ active _ packet _ size (for downlink, that is, the size of the data amount newly added each time corresponding to the buffer of the voice bearer). During the validity period of the VoIP service bearer coding rate identification timer VoIPAMM _ RModeCheckTime, executing the following judgment process:

if the packet size VoIP _ active _ packet _ size < VoIP mac mod packet size threshold (i.e. the set threshold) is received during the VoIP activation period, update n1 plus 1. Further, if n1 is greater than or equal to VoIPAMM media pack number, determining that VoIPAMM mode of VoIP service bearer coding is AMR-NB, terminating the VoIPAMM media code rate recognition timer, and resetting related recording variables; otherwise, no operation is performed, and the subsequent processing is continued.

If the packet size VoIP _ active _ packet _ size received in the VoIP activation period is greater than or equal to VoIP amarmodeppedcetsizetzethreshold, update n2 plus 1. Further, if n2 is greater than or equal to VoIPAMM media pack number, determining that VoIPAMM mode of VoIP service bearer coding is AMR-WB, terminating the VoIPAMM media code timer of VoIP service bearer coding rate identification, and resetting related recording variables; otherwise, no operation is performed, and the subsequent processing is continued.

When a VoIP service bearer coding rate recognition timer, times out, if n1< VoIP service bearer packing number, and n2< VoIP service bearer packing number, then the following judgment process is executed:

if n1> n2, determining that the VoIP service bearer coding mode is AMR-NB;

otherwise, if n1 is not more than n2, the VoIP service bearer coding mode is determined to be AMR-WB.

In an implementation, the first and second manners may be used separately (i.e., only the first or second manner is used to determine the voice coding rate of the VoIP service transmitted by the terminal), or may be used simultaneously (i.e., the first and second manners are used to determine the voice coding rate of the VoIP service transmitted by the terminal), and preferably, if the voice coding rate of the VoIP service transmitted by the terminal, determined according to the MBR parameter corresponding to the bearer used for transmitting the VoIP service of the terminal, is different from the voice coding rate of the VoIP service transmitted by the terminal, determined according to the size of the received data packet of the VoIP service of the terminal, the voice coding rate of the VoIP service transmitted by the terminal, determined according to the MBR parameter corresponding to the bearer used for transmitting the VoIP service of the terminal, is used as the final voice coding rate of the VoIP service transmitted by the terminal. That is, when the results obtained by the way one and the way two conflict, the priority of the results obtained by the way one is higher than that of the results obtained by the way two.

The above method process flow may be implemented by a software program, which may be stored in a storage medium, and when the stored software program is called, the above method steps are performed.
