For example, the first terminal estimates the scheduling resources that the first terminal may obtain through information such as SINR, etc., may limit the number of RBs that the user may use and signal conditions to estimate the bandwidth that the user may use, selects a code rate lower than the estimated bandwidth as an alternative list, and sends the alternative list to the called terminal through a message of a call request; for example, the video frequency code rate supported by the terminal is {384kbps,768kbps,1.5Mbps }, when the terminal measures the current wireless signal and estimates that the used bandwidth is 1Mbps, the calling terminal will generate a {384kbps,768kbps } list to be put in the call request message to the called terminal.
Step 403, the second terminal receives the first call update message sent by the first terminal.
Specifically, after receiving the first call update message, the second terminal first measures the current wireless signal condition, such as SINR and other information; then, estimating the scheduling resource which can be obtained by the method, limiting the number of RBs which can be used by a user and estimating the bandwidth which can be used by the user according to the signal condition; for example, the available bandwidth resource is 1.6 Mbps; and then, after taking the intersection of the code rate list carried by the call request message and the code rate list supportable by the called terminal, selecting the maximum code rate lower than the estimated available bandwidth of the called terminal in the set as the code rate of the audio or video call. For example, specifically, the video bitrate supported by the second terminal is {384kbps,768kbps,1.5Mbps }, the intersection of the bitrate list of the second terminal and the first bitrate list is {384kbps,768kbps }, and the maximum bitrate lower than the estimated available bandwidth of the called terminal in {384kbps,768kbps } is selected as 768 kbps.
Step 404, the first terminal receives a second call update message sent by the second terminal.
And 405, the first terminal determines the QoS characteristics of the wireless bearers of the calling terminal and the called terminal according to the new code rate.

step 501, the first terminal sends a first call update message to the second terminal.
Specifically, when detecting that the wireless signal is deteriorated or the error rate is increased, the first terminal calculates the current available bandwidth according to the wireless signal quality such as SINR and the number of RBs available, and if the available bandwidth is lower than the currently selected code rate, initiates an audio or video call update message to the called terminal, where the message carries a list of code rates lower than the currently estimated available bandwidth; for example, the available bandwidth resource is 600kbps, which is lower than the currently used 768kbps, and the code rate list in the update message sent by the calling terminal is 384 kbps.
Step 502, the second terminal receives the first call update message sent by the first terminal.
Specifically, the second terminal measures the current wireless signal condition, such as SINR and other information; then, estimating the scheduling resource which can be obtained by the method, limiting the number of RBs which can be used by a user and estimating the bandwidth which can be used by the user according to the signal condition; the estimated available bandwidth is 1.6Mbps, however, after taking the intersection of the code rate list carried by the call update message and the code rate list supportable by the called terminal, the maximum code rate lower than the estimated available bandwidth of the called terminal in the intersection is selected as the code rate of the audio or video call, and the code rate is sent to the calling terminal through the call update confirmation message. And if the intersection of the list {384kbps } carried in the update message and the list {384kbps,768kbps and 1.5Mbps } of the supportable code rate of the called terminal is {384kbps } which is lower than the estimated available bandwidth of the called terminal by 1.6Mbps, the called terminal carries 384kbps information in the call update confirmation message.
Step 503, the core network initiates the QoS characteristic update of the audio or video radio bearer of the first terminal and the second terminal according to the updated code rate.
And step 504, the first terminal and the second terminal use the new code rate to carry out audio or video call.

step 602, the first terminal receives a third call update message sent by the base station.
Specifically, a code rate list which is lower than a third code rate carried in a third call updating message is selected to generate a code rate list; for example, according to 500kbps sent by the eNodeB, the {384kbps } is selected from the code rate list {384kbps,768kbps,1.5Mbps } supported by the first terminal, and is carried in the first update message and sent to the second terminal;
step 603, the second terminal receives the first call update message sent by the first terminal.
Specifically, the second terminal measures the current wireless signal condition, such as SINR and other information; then, estimating the scheduling resource which can be obtained by the method, limiting the number of RBs which can be used by a user and estimating the bandwidth which can be used by the user according to the signal condition; the estimated available bandwidth is 1.6Mbps, however, after taking the intersection of the code rate list carried by the call update message and the code rate list supportable by the called terminal, the maximum code rate lower than the estimated available bandwidth of the called terminal in the intersection is selected as the code rate of the audio or video call, and the code rate is sent to the calling terminal through the call update confirmation message. And if the intersection of the list {384kbps } carried in the update message and the list {384kbps,768kbps and 1.5Mbps } of the supportable code rate of the called terminal is {384kbps } which is lower than the estimated available bandwidth of the called terminal by 1.6Mbps, the called terminal carries 384kbps information in the call update confirmation message.
And step 604, the core network initiates the update of the QoS characteristics of the audio or video radio bearer of the first terminal and the second terminal according to the updated code rate.
And step 605, the first terminal and the second terminal use the new code rate to carry out the audio or video call.
