[0074] Figure 1 It is a schematic diagram of the architecture of a communication system according to an embodiment of the present disclosure.

[0075] like Figure 1 As shown, the communication system 100 includes two or more terminals, wherein when the number of terminals is 2, they correspond to terminal 101 and terminal 102 respectively.

[0076] In some embodiments, the above-mentioned terminal includes, for example, a mobile phone, a wearable device, an Internet of Things device, a car with communication function, a smart car, a tablet computer (Pad), a computer with wireless transceiver function, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal device in industrial control, a wireless terminal device in self-driving, a wireless terminal device in remote medical surgery, a wireless terminal device in a smart grid, a wireless terminal device in transportation safety, a wireless terminal device in a smart city, and at least one of a wireless terminal device in a smart home, but is not limited to these.

[0077] In some embodiments, terminal 101 may be a device that initiates a voice call, and terminal 102 may be a called device.

[0078] It is understandable that terminal 101 can initiate a voice call to terminal 102 through the network device.

[0079] In some embodiments, if the call is silent, the following solutions may be used but are not limited to:

[0080] Solution 1: For the user-perceived silence problem, for example, there is actually data but the user identifies it as silence due to severe packet loss. The bit error rate can be dynamically reduced by statistically analyzing the packet loss rate to ensure the call. This situation is usually caused by poor cell signal indicators. At this time, the silence of the call can be detected by terminal-side measurements. It is usually caused by poor cell wireless environment, such as electromagnetic interference, and is relatively rare due to network-side configuration problems.

[0081] Solution 2: Operators can optimize network layout and parameters through network optimization strategies, such as adjusting cell parameters based on the statistics of field measurements of call connection, silence, and call drop rates. This is usually a maintenance and optimization process led by operators.

[0082] Solution 3: The terminal sets a silent timer, and when the timer expires, the terminal actively hangs up the call. This solution is usually just to reduce the use of invalid network resources. At the same time, it reduces the user's invalid call time when the user does not actively hang up.

[0083] For the above solutions 1 and 3, they can be supported by terminal chips. The above solution 2 is mainly adopted by network operators and is a solution that continuously invests manpower to collect data and feedback to achieve optimization.

[0084] Among them, the above solution 1 cannot solve the problem of silent calls, but can only improve stability under the premise of sound. Solution 2 is a network optimization solution that requires continuous investment of manpower optimization according to the actual network. Solution 3 can only hang up the call within a specific time when the silent problem occurs, thereby releasing network bandwidth resources and user call resources. In other words, the above solutions cannot solve the problem of silent calls.

[0085] In a 4G or 5G cellular network, there is silence after a call is connected, which means there are no voice packets in the downlink.

[0086] There is an essential difference between silent call scenarios and user mute scenarios. The difference is that when the speaking user chooses to mute, in order to ensure the hearing experience of the other user, the sender (note that the sender can refer to the voice speaking end or the network device) needs to generate comfort noise. At this time, from the data plane of the other end, there are approximately periodic downlink data packets. This comfort noise is usually achieved through silence description (Silence Insertion Descriptor, SID) frames. When the other end receives the SID frame, it will generate comfort noise according to the algorithm and play it.

[0087] That is to say, in the silent call scenario, there is no downlink voice data packet, while in the user silent scenario, there is a downlink voice data packet, which can generate comfortable noise and play it at the other end. In addition, considering the real call environment, even if the user does not speak during the call, there will usually be a certain amount of background noise, and finally a downlink voice data packet will be generated at the other end.

[0088] In order to effectively solve the problem of silent calls, the present disclosure provides the following call processing method, terminal, call system and storage medium.

[0089] Figure 2A FIG. 1 is an interactive schematic diagram of a call processing method according to an embodiment of the present disclosure. Figure 2A As shown, the embodiment of the present disclosure relates to a call processing method, and the method includes:

[0090] Step S2100: Terminal 101 determines the timing duration of the second timer.

[0091] In some embodiments, the second timer T2 may be a timer that triggers the terminal 101 to initiate cell reselection in a call silence scenario.

[0092] In some embodiments, the name of the second timer T2 is not limited and can be interchangeable with "silence timer", "silence detection timer", "cell reselection timer" and the like.

[0093] In one example, when the second timer T2 times out, the terminal 101 may initiate cell reselection.

[0094] In an example, the timing duration of the second timer T2 may be M2, where M2 may be a non-negative value and may be in units of seconds (s) or milliseconds (ms).

[0095] In some embodiments, the value of M2 may be configured by a network device.

[0096] In one example, the network device may configure the value of M2 in a system message.

[0097] For example, for a Long Term Evolution (LTE) system, the value of M2 may be set in a system message, such as a System Information Blockn (SIBn), where n is a positive integer.

[0098] Exemplarily, the timing duration of the second timer T2 may be set in the terminal timer and constant (ue-TimersAndConstants) field of SIB2:

[0099]

[0100]

[0101] Exemplarily, for a New Radio (NR) system, the value of M2 may be set in a system message, such as a system information block type m (System Information Block Type m), where m is a positive integer.

[0102] Exemplarily, the timing duration of the second timer T2 may be set in the ue-TimersAndConstants field of System Information Block Type 1:

[0103]

[0104] The above description is merely an exemplary description, and the present disclosure does not limit the manner in which the network device sets the timing duration of the second timer T2.

[0105] Accordingly, the terminal 101 may determine the timing duration of the second timer T2 by receiving network configuration, including but not limited to receiving a system message.

[0106] In some embodiments, the terminal 101 may determine the timing duration of the second timer T2 based on a predefined method.

[0107] In one example, the terminal 1011 determines the value of M2 as a default value based on a predefined method. For example, M2 is 5, and the timing duration of T2 is 5s.

[0108] In an example, when the terminal 101 determines that the network device is not configured with a value for M2, the terminal 101 may determine that the value for M2 is a default value based on a predefined method.

[0109] Step S2101: Terminal 101 detects that a call is in a silent state and starts a first timer and a second timer.

[0110] In some embodiments, terminal 101 initiates a voice call to terminal 102 .

[0111] In the embodiments of the present disclosure, calls, voice calls, and video calls may be equivalent.

[0112] In some embodiments, if the terminal 101 does not detect any downlink voice data packets, it determines that the call is in a silent state.

[0113] In some embodiments, the first timer T1 may be a timer that triggers the terminal 101 to end a call in a silent call scenario.

[0114] In some embodiments, the name of the first timer T1 is not limited and can be interchangeable with "silence timer", "silence detection timer" and the like.

[0115] In an example, the timing duration of the first timer T1 can be determined based on a predefined method, assuming it is M1, and the unit can be s or ms, where M1 can be a non-negative value. Exemplarily, M1 can belong to the interval [10s, 30s].

[0116] In one example, when the first timer T1 times out, the terminal 101 may initiate a call termination request to hang up the call.

[0117] In some embodiments, considering that the value of M1 is large, that is, the terminal 101 needs to wait for 10s to 30s before hanging up the call, and cannot restore the call to a sound state, therefore, in the disclosed embodiment, the timing duration M2 of the second timer T2 may be smaller than the timing duration M1 of the first timer T1, so that the terminal 101 initiates cell reselection before the call becomes silent and automatically hangs up the call, thereby increasing the probability of restoring a normal call.

[0118] In some embodiments, the terminal 101 determines the maximum number of cell reselections N2 when the call is silent based on the configuration of the network device and / or a predefined method.

[0119] In some embodiments, in order to try to restore the normal call as much as possible before the terminal 101 automatically ends the call, the product of the timing duration M2 of the second timer and the maximum number of cell reselections N2 can be less than the timing duration M1 of the first timer, that is, M2×N2 <M1。

[0120] Step S2102: When the second timer times out and the call is still in silent state, the terminal 101 initiates cell reselection.

[0121] In some embodiments, before the second timer T2 times out, the terminal 101 receives a voice data packet, that is, the call is restored to the voice state, and the first timer T1 and the second timer T2 can be stopped.

[0122] In some embodiments, when the second timer T2 times out and the call is still in a silent state, the terminal 101 automatically initiates a cell reselection. In some embodiments, if the cell reselection is successful and the terminal 101 is in the first cell after the reselection and the call is in a voiced state, steps 2103 to 2104 may be continued.

[0123] In some embodiments, if the cell reselection is successful, but the call of the terminal 101 is still in a silent state in the first cell after the reselection, the process may continue from 2105 to step S2106.

[0124] In some embodiments, if the cell reselection fails, steps S2107 to S2109 may continue to be executed.

[0125] Step S2103: stop the first timer and the second timer.

[0126] In some embodiments, the cell reselection is successful, and the terminal 101 is in the first cell after the reselection, and the call is in a voice state, at which time the terminal 101 can stop the first timer T1 and the second timer T2.

[0127] Step S2104, continue the call process in the first cell.

[0128] In some embodiments, terminal 101 determines that the call is in a voiced state in the first cell after reselection, and can continue to talk with terminal 102 in the first cell until the call ends or the call is detected to be in a silent state again.

[0129] If the call is detected to be in a silent state again, the terminal 101 can restart the first timer T1 and the second timer T2 and return to step S2102. When the second timer T2 times out and the call is still in a silent state, the terminal 101 initiates cell reselection again.

[0130] In some embodiments, timer restart may refer to the timer restarting. Assuming that the first timer T1 is restarted and its timing duration is 20s, the first timer T1 restarts (counts down) from 20s. Assuming that the second timer T2 is restarted and its timing duration is 5s, the second timer T2 restarts (counts down) from 5s.

[0131] Step S2105: Terminal 101 determines that the first timer continues to time, and restarts the second timer.

[0132] In some embodiments, if the cell reselection is successful, but the call of the terminal 101 is still in a silent state in the first cell after the reselection, the terminal 101 determines that the first timer T1 continues to time, and restarts the second timer T2.

[0133] For example, the timing duration of the first timer T1 is 20s, the timing duration of the second timer T2 is 5s, the second timer T2 times out, the terminal 101 initiates cell reselection, the cell reselection is successful, but the call of the terminal 101 is still in a silent state in the first cell after the reselection. At this time, the first timer T1 continues (countdown), and the second timer T2 starts again from 5s.

[0134] Step S2106: The second timer times out, the call is still in a silent state, and the terminal 101 initiates cell reselection again.

[0135] In some embodiments, after the second timer T2 is restarted, if a voice data packet is received before the second timer T2 times out, the terminal 101 determines that the call is restored to the voice state and can stop the first timer T1 and the second timer T2.

[0136] In some embodiments, after the second timer T2 is restarted, if the second timer T2 times out again and the call is still in a silent state, the terminal 101 initiates cell reselection again. If the cell reselection is successful, and the terminal 101 is in the first cell after reselection and the call is in a voiced state, the process may return to step 2103 to step S2104. If the cell reselection is successful, but the terminal 101 is in the first cell after reselection and the call is still in a silent state, the process may return to step 2105 to step S2106. If the cell reselection fails, the process may continue to execute steps S2107 to step S2109.

[0137] Step S2107: Terminal 101 subtracts 1 from the first reselection number to obtain a second reselection number.

[0138] In some embodiments, if the cell reselection fails, the first reselection number N2' may be reduced by 1 to obtain a second reselection number N2". The first reselection number N2' is less than or equal to the maximum number N2 of cell reselections.

[0139] The maximum number of cell reselection times N2 may be determined based on the timing duration M1 of the first timer T1 and the timing duration M2 of the second timer T2.

[0140] For example, N2 can be determined by taking a downward value based on the quotient of M1 and M2, that is,

[0141] For example, if M1 is 23s and M2 is 5s, then N2 is 4.

[0142] The first reselection number is equal to the difference between the maximum number of cell reselection times N2 and the number of cell reselection failures, that is, the first reselection number refers to the remaining number of times the terminal 101 can perform cell reselection.

[0143] It is understandable that if the cell reselection fails for the first time, N2' is equal to N2. If the cell reselection fails again subsequently, the first reselection number N2' is less than the maximum number of cell reselections N2.

[0144] In one example, a counter may be set on the terminal 101, and the timer starts counting from N2. Each time a cell reselection failure occurs, the counter is decremented by 1, and the value of the counter after each decrement is equal to the second reselection number.

[0145] In an example, each time the terminal 101 starts or restarts the first timer T1, the counter may be restarted at the same time.

[0146] In some embodiments, if the second reselection number N2" is greater than 0, that is, the terminal 101 can still perform cell reselection, then step S2108 is continued.

[0147] In some embodiments, if the second reselection number N2" is equal to 0, that is, the terminal 101 can no longer perform cell reselection, then step S2109 is continued.

[0148] Step S2108: Terminal 101 determines that the first timer continues to time, and restarts the second timer.

[0149] In some embodiments, if the terminal 101 determines that cell reselection can still be performed, the first timer T1 can continue timing and the second timer T2 can be restarted.

[0150] Further, when the second timer T2 times out and the call is still in a silent state, the terminal 101 initiates cell reselection again. If the cell reselection is successful, and the terminal 101 is in the first cell after reselection and the call is in a voiced state, the process may return to step 2103 to step S2104. If the cell reselection is successful, but the terminal 101 is in the first cell after reselection and the call is still in a silent state, the process may return to step 2105 to step S2106. If the cell reselection fails, the process may continue to execute steps S2107 to step S2109.

[0151] Step S2109: Terminal 101 waits for the first timer to time out.

[0152] In some embodiments, if the second reselection number N2" is equal to 0, that is, the terminal 101 can no longer perform cell reselection, the terminal 101 can wait for the first timer to time out.

[0153] In some embodiments, if no voice data packet is received before the first timer times out, the terminal 101 continues to perform step S2110. If a voice data packet is received before the first timer times out, the terminal 101 continues to perform step S2111.

[0154] Step S2110: Terminal 101 ends the call process.

[0155] In some embodiments, if no voice data packet is received before the first timer times out, the terminal 101 may actively initiate a call termination request to terminate the call.

[0156] Step S2111, terminal 101 stops the first timer.

[0157] In some embodiments, if a voice data packet is received before the first timer times out, the terminal 101 may stop the first timer T1.

[0158] Furthermore, if call silence is detected again, the process may return to step S2101 to restart the first timer and the second timer.

[0163] In some embodiments, steps S2100 to S2111 are optional, and one or more of these steps may be omitted or replaced in different embodiments.

[0164] In some embodiments, the execution order of steps S2100 to S2111 is not limited.

[0165] In the above embodiments, an effective solution is provided for the situation of silent calls, which improves the user experience of voice calls and has high usability.

[0166] Figure 2B FIG. 1 is an interactive schematic diagram of a call processing method according to an embodiment of the present disclosure. Figure 2B As shown, the embodiment of the present disclosure relates to a call processing method, and the method includes:

[0167] Step S2200: Terminal 101 determines a timing duration of the second timer and a timing duration of the third timer.

[0168] In some embodiments, the implementation manner in which the terminal 101 determines the timing duration of the second timer T2 is similar to the implementation manner of step S2100, which is not repeated here.

[0169] In some embodiments, the third timer may be a timer for counting voice data packets in a silent call scenario.

[0170] In some embodiments, the name of the third timer is not limited and can be interchangeable with "statistical timer", "data packet statistics timer", etc.

[0171] In one example, considering that the continuous counting of whether there are downlink voice data packets by the terminal 101 will bring about a large system overhead, the present disclosure sets a third timer T3. The terminal 101 can count the number of downlink voice data packets when the third timer T3 times out, which is beneficial to reducing system overhead and saving terminal energy consumption.

[0172] In some embodiments, the implementation method of the terminal 101 determining the timing duration M3 of the third timer T3 is similar to the implementation method of determining the timing duration M2 of the second timer T2, which can be configured by the network device or determined by the terminal 101 based on a predefined method. The specific implementation process is not repeated here.

[0173] In an example, M3 may be smaller than M2 and larger than the duration of a speech frame, wherein the duration of a speech frame is 20 ms. M3 may be larger than 20 ms and smaller than M2, for example, M3 may be 1 s.

[0174] Step S2201: Terminal 101 detects that the call is in a silent state and starts a first timer, a second timer and a third timer.

[0175] In some embodiments, if the terminal 101 does not detect any downlink voice data packets, it determines that the call is in a silent state.

[0176] In some embodiments, when the terminal 101 detects that the call is in a silent state, it starts the first timer T1, the second timer T2 and the third timer T3.

[0177] Step S2202: When the third timer times out, the terminal 101 counts the second number of voice data packets.

[0178] In some embodiments, the terminal counts the second number n1 of voice data packets in the current cycle. pkt .

[0179] The duration of each cycle is equal to the timing duration of the third timer.

[0180] In some embodiments, if the second number is greater than the first number n0 pkt , then continue to execute step S2203, if the second number is equal to the first number n0 pkt , then continue to execute step S2204.

[0181] Among them, the first number n0 pkt It is the number of voice data packets counted when the third timer times out last time, that is, the number of voice data packets in the previous cycle.

[0182] Step S2203: Terminal 101 stops the first timer, the second timer and the third timer.

[0183] In some embodiments, if the second number is greater than the first number, it means that there are voice data packets in the current period, and the terminal 101 can stop T1, T2 and T3.

[0184] Furthermore, n0 can be set pkt =n1 pkt , for example, T3 times out, the second number n1 pkt =50, the first number n0 pkt =0, the first number n0 needs to be updated pkt , set it to the same as n1 pkt equal, so that the subsequent cycle can determine the number of voice packets in the previous cycle.

[0185] In some embodiments, if the call is subsequently detected to be in a silent state again, T1 and T2 are restarted, and T3 is restarted at the same time.

[0186] Step S2204: Terminal 101 determines that the first timer and the second timer continue to time, and restarts the third timer.

[0187] In some embodiments, if the second number is equal to the first number, it means that there is no voice data packet in the current period, and the terminal 101 can allow T1 and T2 to continue timing and restart T3.

[0188] When T3 times out, the process returns to step S2202, and the terminal 101 counts the second number of voice data packets again.

[0189] Step S2205: the second timer times out, the call is still in a silent state, and the terminal 101 initiates a cell reselection.

[0190] In some embodiments, the implementation of step S2205 is similar to that of step S2102 and will not be repeated here.

[0191] If the cell reselection is successful, and the terminal 101 is in the first cell after the reselection, and the call is in a voiced state, then the steps 2206 to 2207 may be continued. If the cell reselection is successful, but the terminal 101 is in the first cell after the reselection, and the call is still in a silent state, then the steps 2208 to 2209 may be continued. If the cell reselection fails, then the steps S2210 to S2212 may be continued.

[0192] Step S2206: stop the first timer and the second timer.

[0193] In some embodiments, the implementation of step S2206 is similar to that of step S2103 and will not be repeated here.

[0194] Step S2207, continue the call process in the first cell.

[0195] In some embodiments, the implementation of step S2207 is similar to that of step S2104 and will not be repeated here.

[0196] Step S2208: Terminal 101 determines that the first timer continues to time, and restarts the second timer.

[0197] In some embodiments, the implementation of step S2208 is similar to that of step S2105 and will not be repeated here.

[0198] It should be noted that, when the second timer is restarted, the terminal 101 may restart the third timer T3.

[0199] Step S2209: the second timer times out, the call is still in a silent state, and the terminal 101 initiates cell reselection again.

[0200] In some embodiments, the implementation of step S2209 is similar to that of step S2106 and will not be repeated here.

[0201] Step S2210: Terminal 101 subtracts 1 from the first reselection number to obtain a second reselection number.

[0202] In some embodiments, the implementation of step S2210 is similar to that of step S2107 and is not described again here.

[0203] If the second reselection number is greater than 0, continue to execute step S2211; if the second reselection number is equal to 0, continue to execute step S2212.

[0204] Step S2211, the terminal 101 determines that the first timer continues to time, and restarts the second timer.

[0205] In some embodiments, the implementation of step S2211 is similar to that of step S2108 and will not be repeated here.

[0206] Step S2212: Terminal 101 waits for the first timer to time out.

[0207] In some embodiments, the implementation of step S2212 is similar to that of step S2109 and will not be repeated here.

[0208] In some embodiments, if no voice data packet is received before the first timer times out, then step S2213 is continued to be executed. If a voice data packet is received before the first timer times out, then step S2214 is continued to be executed.

[0209] Step S2213: Terminal 101 ends the call process.

[0210] In some embodiments, the implementation of step S2213 is similar to that of step S2110 and will not be repeated here.

[0211] Step S2214, terminal 101 stops the first timer.

[0212] In some embodiments, the implementation of step S2214 is similar to the implementation of step S2111 and will not be repeated here.

[0213] In some embodiments, steps S2200 to S2214 are optional, and one or more of these steps may be omitted or replaced in different embodiments.

[0214] In some embodiments, the execution order of steps S2200 to S2214 is not limited.

[0215] In the above embodiment, a third timer is set, and voice data packets are counted when the third timer times out, which reduces system overhead, saves terminal energy consumption, and provides an effective solution for silent calls, thereby improving the user experience of voice calls and having high availability.

[0293] In the above embodiment, a third timer is set, and voice data packets are counted when the third timer times out, which reduces system overhead, saves terminal energy consumption, and provides an effective solution for silent calls, thereby improving the user experience of voice calls and having high availability.

[0294] Figure 3C FIG. 1 is an interactive schematic diagram of a call processing method according to an embodiment of the present disclosure. Figure 3C As shown, the embodiment of the present disclosure relates to a call processing method, which is executed by the terminal 101 and includes:

[0295] Step S3301, start the first timer and the second timer.

[0296] In some embodiments, optional implementations of step S3301 can be found in Figure 2A Optional implementations of step S2101, and Figure 2A Other related parts in the embodiments involved will not be described in detail here.

[0297] Step S3302, initiate cell reselection.

[0298] In some embodiments, when the second timer T2 times out and the call is still in a silent state, the terminal 101 automatically initiates a cell reselection.

[0299] In some embodiments, optional implementations of step S3302 can be found in Figure 2A Optional implementations of step S2102, and Figure 2A Other related parts in the embodiments involved will not be described in detail here.

[0300] In some embodiments, steps S3301 to S3302 are optional, and one or more of these steps may be omitted or replaced in different embodiments.

[0301] In some embodiments, the execution order of step S3301 to step S3302 is not limited.

[0302] In the above embodiments, an effective solution is provided for the situation of silent calls, which improves the user experience of voice calls and has high usability.

[0303] The above process is further illustrated below with examples.

[0304] In the disclosed embodiment, two new timers are added, namely timer T2 and timer T3. Among them, T2 is used to monitor the timer for silence after the call is connected and the silence continues, and T3 is the interval for starting the silence statistics, the voice silence statistics process. The cell reselection process initiated after T2 times out, this process is based on the current network standard (such as LTE or NR) and follows the standard to initiate the corresponding cell reselection process.

[0305] There are two solutions for implementing T2:

[0306] The network side configures in the system message, adding txxx (xxx is a digital number) before the terminal resides in the current cell, and receives the system message broadcast (the timer size here is 5000ms as an example)

[0307] For LTE (4G), the ue-TimersAndConstants field of the system message SIB2 can be increased:

[0308]

[0309]

[0310] For NR (5G), the ue-TimersAndConstants field in the system message systemInformation Block Type1 can be added:

[0311]

[0312] In the IMS system, there is a temporary network failure or resource allocation problem during a voice call, which leads to downlink silence. In this scenario, the silence will last for a long time and cannot be automatically restored, seriously affecting the user experience. There is currently no better process solution. Common solutions include the technical solution 2 mentioned above. Usually, the terminal will start a data packet statistics timer, for example, through the timer T, to count the downlink data packets. If the statistical result is 0 when the timer times out, the terminal will initiate the active call drop process. This method cannot improve the user experience well.

[0313] Therefore, the embodiments of the present disclosure provide a standard process for detecting the silent call problem and timely reselecting a suitable cell for the user, so as to maximize the user's call experience under a given network environment.

[0314] In the embodiment of the present disclosure, three timers are involved: T1, T2, T3, and a counter N2, wherein:

[0315] T1: is the silent timer. Currently, UE manufacturers usually set it. The common value range is [10s, 30s], and the typical value is 20s. When T1 times out, the UE initiates a call hang-up request (BYE).

[0316] T2: A newly defined timer for this solution. If no downlink voice data is received for a period of time equal to the T2 timer duration, the T2 timer will time out. The recommended typical value / default value of the timer duration is 5s.

[0317] T3: A newly defined timer for this solution, used to count the statistical counting period after receiving downlink voice data. When T3 times out, check whether the number of newly received voice data frames is greater than 0. Because the period of a single voice frame is usually 10ms to 30ms per frame, with a typical value of 20ms, if checking is performed on each received frame, the system timer burden will increase and the user experience will not be significantly improved. The recommended typical value of T3 is 1s.

[0318] N2: is the reselection counter. The number of reselections must be set in design to avoid the time overhead caused by too many reselections, which weakens the benefits of improving the silence problem by reselecting cells.

[0319] The call processing flow is as follows: Figure 4 As shown, the following steps may be included:

[0320] Step S4101, before the call, obtain the latest system message txxx parameter value, if the system message contains it, T2 = txxx timer value, if the system message does not contain it, the default T2 duration is 5s.

[0321] Step S4102: The call starts.

[0322] Step S4102-1 starts the timer: T1, detects the duration of no voice in the downlink, and the statistical start and stop rules of T1 have been implemented and will not be described here;

[0323] Step S4102-2: Start timer T2 to detect the duration of no downlink voice; and use timer T3 as the detection period. Detect whether each new T3 period has new downlink voice RTP packets compared to the previous period. Initial packet count n0 pkt =0, specifically:

[0324] i) T3 times out, the statistical value is n1 pkt , if n1 pkt >n0 pkt , then use n1 pkt Modify n0pkt , that is: n0 pkt =n1 pkt , restart T2 and T3 at the same time; (for example, T3 times out, n1 pkt =50,n0 pkt =0, then modify n0 pkt =50, that is: n0 pkt =n1 pkt , indicating that during T3, the network has always had downlink voice. After restarting T2 and T3, n1 pkt Continue counting. )

[0325] ii) T3 times out, the statistical value is n1 pkt , if n1 pkt =n0 pkt , restart only T3;

[0326] iii) T2 times out, n1 pkt =0,n0 pkt =0; lower the current cell reselection priority and initiate cell reselection.

[0327] Step S4102-3 initiates cell reselection;

[0328] i) If the cell is reselected successfully, jump to step S4102-2. Whether T1 is reselected is determined according to the original T1 algorithm strategy (for example, if there is still no sound after switching, the actual effect is that there is no sound, so according to the usual T1 algorithm, it is reasonable to continue timing without restarting; if there is sound after switching, because there is downlink voice data, the original T1 algorithm will automatically restart T1 and re-time).

[0329] ii) If the cell reselection fails, the reselection count is N2-1. If N2-1>0, jump to step S4102-2, otherwise jump to step S4102-4.

[0330] Step S4102-4, wait for T1 to time out. If a downlink data packet appears during the waiting process, T1 is restarted and jumps to step S4102-1; if T1 times out, the terminal initiates the call termination.

[0331] pass Figure 4 It can be seen that the relationship between the duration of each timer and the size of the counter can be maintained as follows:

[0332] N2≥1; that is, the cell must be reselected at least once.

[0333] T2 x N2 <T1;

[0334] For example: the reselection timer T2 is 5s long, the number of reselections is 2, and the original downlink real-time transport protocol RTP (Realtime Transport Protocol) or real-time transport control protocol (Real-time Control Protocol, RTCP) timeout timer T1 is 20s long, then 5x 2<20; that is, T3 <T2<T1。

[0335] Function of T3: Common voice frames are 20ms / frame. If the timer is started for downlink voice data statistics at each frame interval, the system overhead is relatively large and meaningless for normal voiced call scenarios. Therefore, in order to avoid the impact of too high frequency of starting the timer on system performance while maintaining the effectiveness of statistics, a special T3 can be set for comparison, for example: T3 = 1s. Each time T3 times out, the latest downlink voice data packet statistics can be compared with the last T3 start to confirm whether there is a problem of no downlink data.

[0336] The selection of N2 can be rounded down according to the timer ratio to get the reference value.
