[0004] With the development of communication technology, the call service under the 5th Generation Mobile Communication Technology (5G) is becoming more and more common. Generally, after the terminal camps on 5G, it will be in a connected state, an idle state or a deactivated state. Among them, when the terminal has no service to interact with the network, the terminal will automatically enter the idle state or the deactivated state after a certain time for energy saving, and keep synchronization with the network through Discontinuous Reception (DRX).

[0005] Generally, in the case that the terminal is in the idle state or the deactivated state, the terminal can listen to the synchronization signal and the Physical Broadcast Channel Block (SS / PBCH Block) broadcast by the network side device according to the period of DRX to keep synchronization with the network. That is, the terminal will constantly switch between the idle state and the connected state, or constantly switch between the deactivated state and the connected state in order to meet different service requirements.

[0006] However, if the SSB signal of the cell accessed or camped by the terminal is poor, it may cause the terminal to fail to parse the synchronization signal, thereby causing the terminal to be out of synchronization with the network, missing the paging message of the network, and further causing the call connection rate of the terminal to be low.

[0024] The communication method, device, terminal, medium, and computer program product provided by the embodiments of the present application will be described in detail below in conjunction with the drawings and specific embodiments and their application scenarios.

[0025] The communication method, device, terminal, medium, and computer program product provided by the embodiments of the present application can be applied to the scenario of a terminal connecting a call, especially the scenario of a terminal connecting a call when the terminal is in an idle state or a deactivated state.

[0026] With the gradual increase of the coverage range of the 5th Generation Mobile Communication Technology (5G) network, the proportion of terminals camping on 5G in all terminals is also increasing, and users are more and more common to conduct business under the 5G network. Among them, the call service under 5G is a common service.

[0027] Generally, after the terminal camps on 5G, it is usually in a connected state or an idle state or a deactivated state. Specifically, when the terminal has no business to interact with the network, the terminal will automatically enter the idle state or the deactivated state after a certain period of time for energy saving consideration; when the user normally uses the terminal to surf the Internet, the terminal will enter the connected state and interact with the network for business, and when the terminal ends the business interaction with the network and has no new network business to process, the terminal can enter the idle state or the deactivated state and listen to the SSB broadcast by the network according to the DRX period to keep synchronization with the network. That is, the terminal will constantly switch between the idle state or the deactivated state and the connected state in order to meet different business needs.

[0028] However, if the SSB signal of the cell accessed or camped by the terminal is poor, the terminal will fail to parse the synchronization signal, resulting in out-of-sync with the network, missing the paging message of the network, and thus leading to a low call connection rate of the terminal.

[0029] Although the current cell selection scheme is usually based on the signal strength of the cell's Reference Signal Receiving Power (RSRP) and the signal quality of the cell's Reference Signal Receiving Quality (RSRQ) to perform cell switching, that is, the terminal can select the optimal cell with the best RSRP signal strength and RSRQ signal strength for camping. However, this cell selection scheme cannot avoid the problem of missing paging reception caused by poor SSB signal of the cell camped by the terminal in the idle state or the deactivated state. For example, the terminal may camp on the optimal cell, but when the terminal is in the idle state or the deactivated state, the received SSB SNR may be poor, and at this time, according to the above-mentioned cell selection scheme, the terminal will camp on the cell, thereby causing the problem of missing paging reception in the idle state or the deactivated state of the terminal, affecting the call service, and leading to a low call connection rate of the terminal.

[0030] The communication method, device, terminal, medium and computer program product provided in the embodiments of the present application can avoid the terminal missing the paging of the network in the case that the SSB signal of the cell in which the terminal resides is poor in the idle state or the deactivated state of the terminal, for example, a call forwarding number can be set, or the period of DRX can be shortened, or the terminal can enter the connected state, so as to increase the time for the terminal in the connected state to analyze the paging and avoid the terminal missing the paging. The terminal can also access a neighboring cell to avoid the terminal missing the paging. In this way, the possibility of successful call establishment of the terminal is improved, and the call connection rate of the terminal is improved.

[0031] The execution subject of the communication method provided in the embodiments of the present application can be a communication device. Illustratively, the communication device can be a terminal, or a component in the terminal, for example, an integrated circuit or a chip. The communication method provided in the embodiments of the present application will be illustratively described below taking the terminal as an example.

[0032] The embodiments of the present application provide a communication method, and FIG. 1 shows a flowchart of a communication method provided in the embodiments of the present application. The method can be applied to a first terminal. As shown in FIG. 1, the communication method provided in the embodiments of the present application can include the following steps 101 and 102, or the following steps 101 and 103.

[0033] Step 101: The first terminal acquires the SSB SNR of a first cell in which the first terminal resides when the first terminal is in an idle state or a deactivated state.

[0034] In some embodiments of the present application, the first cell can be one cell in which the first terminal resides.

[0035] Illustratively, the first cell can be one 5G cell in which the first terminal resides.

[0036] It can be understood that the first terminal can perform beam management and mobility management based on the beam measurement result of the SSB in the case of being in the idle state or the deactivated state. Therefore, the first terminal can record the SSB SNR of the first cell in which the first terminal resides when the first terminal is in the idle state or the deactivated state after the first terminal resides in the first cell, so as to determine the signal quality of the SSB signal of the first cell.

[0037] In some embodiments of the present application, when the first terminal is in the connected state, the first terminal can track the time-frequency offset according to the TRS to parse the paging cell; and when the first terminal is in the idle state or the deactivated state, since the first terminal cannot acquire the TRS, the first terminal can only parse the paging message according to the SSB. In this way, the first terminal can determine the size of the possibility of successfully establishing a call through the first cell when the first terminal is in the idle state or the deactivated state according to the signal quality of the SSB signal of the first cell, so as to determine whether to perform the step 102 or the step 103 described below.

[0038] The step 102: when the SSB SNR is less than the first threshold value, the first terminal sets the call forwarding number of the first SIM card to the number of the second SIM card.

[0039] The first SIM card can be a SIM card in the first terminal that is camped in the first cell.

[0040] In some embodiments of the present application, the SSB SNR being less than the first threshold value can indicate that the SSB signal of the first cell is poor, at this time, the first terminal cannot successfully parse the synchronization signal when in the idle state or the deactivated state, which can cause the first terminal to miss the paging message of the network, thereby causing the first terminal to miss the incoming call from other users.

[0041] In some embodiments of the present application, when the SSB SNR is less than the first threshold value, the first terminal can actively set the call forwarding number of the SIM card camped in the first cell to the number of the second SIM card, so that the user can receive the paging message through the second SIM card.

[0042] In some embodiments of the present application, the first threshold value can be a default value of the terminal, a value set by the user, or a value configured by the network side device. The embodiments of the present application are not limited specifically.

[0043] In some embodiments of the present application, the first terminal can include at least two SIM cards, and the second SIM card can be a SIM card other than the first SIM card in the first terminal, or the second SIM card can be a SIM card in the second terminal.

[0044] In some embodiments of the present application, when the first terminal includes at least two SIM cards, the second SIM card can be a SIM card other than the first SIM card in the first terminal.

[0045] Exemplarily, the first terminal includes the SIM card 1 and the SIM card 2, and the SIM card residing in the first terminal in the first cell is the SIM card 1. In the case that the first terminal is in the idle state or the deactivated state, if the SSB SNR of the first cell is less than the first threshold value, the terminal can automatically set the call forwarding number of the SIM card 1 to the SIM card 2. In this way, when other users call the SIM card 1 of the local user terminal, the local user can directly answer the call of the SIM card 1 through the SIM card 2, thereby avoiding the problem of missed paging due to the poor SSB signal of the first cell in which the terminal resides.

[0046] In some embodiments of the present application, the second SIM card can also be a SIM card in the second terminal.

[0047] In some embodiments of the present application, the second terminal is different from the first terminal.

[0048] In some embodiments of the present application, the second terminal and the first terminal can belong to the same user or different users. The embodiments of the present application are not limited in this regard.

[0049] Exemplarily, the first terminal resides in the first cell, the first terminal includes the SIM card 1, and the second terminal includes the SIM card 3. In the case that the first terminal is in the idle state or the deactivated state, if the SSB SNR of the first cell is less than the first threshold value, the terminal can automatically set the call forwarding number of the SIM card 1 to the SIM card 3. In this way, when other users call the SIM card 1 of the local user terminal, if the second terminal and the first terminal belong to different users, the user of the second terminal can answer the call of the SIM card 1 for the local user, or the user of the second terminal can pass the second terminal to the local user to answer the call. If the second terminal and the first terminal belong to the same user, the user can directly answer the call of the SIM card 1 through the second terminal. Thus, the problem of missed paging due to the poor SSB signal of the first cell in which the terminal resides can be avoided.

[0050] In this way, the terminal can automatically set the call forwarding number of the SIM card residing in the cell in which the terminal resides in the idle state or the deactivated state, thereby avoiding missed paging of the terminal and improving the call connection rate of the terminal.

[0051] In the case that the SSB SNR is less than the first threshold value, the first terminal performs a first operation based on the first information.

[0052] In some embodiments of the present application, the first information can include at least one of: a TRS SNR of the first cell when the first terminal is in the connected state, and a duration for which the SSB SNR of the first cell is less than a first threshold when the first terminal is in the idle state or the inactive state.

[0053] In some embodiments of the present application, the first operation can include at least one of: shortening a cycle of DRX by the first terminal, entering the connected state by the first terminal, accessing the second cell by the first terminal, and the second cell being a neighbor cell of the first cell.

[0054] In some embodiments of the present application, the TRS SNR of the first cell when the first terminal is in the connected state can be used to indicate a signal quality of the first cell when the first terminal is in the connected state.

[0055] In some embodiments of the present application, the TRS can be a channel status information-reference signal (CSI-RS). When the terminal receives downlink data, the TRS can continuously track and compensate for time offset and track and compensate for frequency offset. Therefore, in the case that the terminal is in the connected state, the signal quality of the first cell can be determined by the TRS SNR of the first cell, so that the success rate of the terminal in parsing the paging message in the connected state can be determined.

[0056] In some embodiments of the present application, the duration for which the SSB SNR of the first cell is less than the first threshold when the first terminal is in the idle state or the inactive state can be used to indicate a duration for which the SSB signal of the first cell is poor.

[0057] It can be understood that, if the duration for which the SSB SNR of the first cell is less than the first threshold when the first terminal is in the idle state or the inactive state is short, the first terminal can ignore the poor SSB signal in the short duration and continue to camp on the first cell. At this time, the terminal continues to camp on the first cell and does not cause the terminal to miss the paging.

[0058] In some embodiments of the present application, shortening the cycle of DRX by the first terminal can make the first terminal switch between the connected state and the idle state, or between the connected state and the inactive state, at a shorter cycle, so that the time for the terminal to parse the paging in the connected state can be increased, and thus the first terminal can avoid missing the paging.

[0059] In some embodiments of the present application, entering the connected state by the first terminal can make the first terminal remain in the connected state in the case that the SSB SNR of the first cell is poor in the idle state or the inactive state, so as to avoid the first terminal missing the paging.

[0060] In some embodiments of the present application, the first terminal accessing the second cell can mean that the first terminal can access a neighbor cell of the first cell to find a neighbor cell whose SSB signal quality can be greater than or equal to the first threshold when the first terminal is in the idle state or the deactivated state, so as to receive the paging message through the neighbor cell.

[0061] The communication method provided by the embodiments of the present application can avoid the terminal missing the network paging in various ways when the terminal resides in a cell whose SSB signal is poor, for example, a call forwarding number can be set, the DRX cycle can be shortened, or the terminal can directly enter the connected state, so as to increase the time for the terminal to analyze the paging in the connected state and avoid the terminal missing the paging. The terminal can also access a neighbor cell to avoid missing the paging. In this way, the possibility of successful call establishment of the terminal is improved, and the call connection rate of the terminal is improved.

[0062] In some embodiments of the present application, the first information can include the TRS SNR of the first cell when the first terminal is in the connected state.

[0063] In some embodiments of the present application, the step 103 can include the following step 103a.

[0064] Step 103a: When the TRS SNR of the first cell when the first terminal is in the connected state is greater than or equal to the second threshold, the first terminal shortens the DRX cycle.

[0065] In some embodiments of the present application, when the first information includes the TRS SNR of the first cell when the first terminal is in the connected state, the first terminal can shorten the DRX cycle when the TRS SNR of the first cell when the first terminal is in the connected state is greater than or equal to the second threshold, so as to increase the time for the terminal to analyze the paging in the connected state, thereby avoiding the first terminal missing the paging.

[0066] For example, the first threshold is 50 dB, the second threshold is 60 dB, and the DRX cycle of the first terminal is 20 s. If the first terminal detects that the SSB SNR of the first cell when the first terminal is in the idle state or the deactivated state is 30 dB, and detects that the TRS SNR of the first cell when the first terminal is in the connected state is 80 dB, the first terminal can shorten the DRX cycle from 20 s to 15 s to avoid the terminal missing the paging.

[0067] In some embodiments of the present application, the second threshold can be default for the terminal, can be set by the user, or can be configured by the network side device. The embodiments of the present application do not make specific limitations.

[0068] In some embodiments of the present application, the second threshold value and the first threshold value can be the same or different. The embodiments of the present application are not limited in this respect.

[0069] In some embodiments of the present application, after the first terminal camps on the first cell, the first terminal can record the TRS SNR strength of the first cell when the first terminal is in the connected state, and record the SSB SNR strength when the terminal enters the idle state or the inactive state, to determine the signal quality of the first cell in real time.

[0070] In some embodiments of the present application, the degree of shortening the cycle of the shortened DRX is terminal default, user set, or network side device configured. The embodiments of the present application are not limited in this respect.

[0071] For example, the first terminal can configure the preferred DRX inactivity timer (preferredDRX-InactivityTimer) duration of the shortened DRX by terminal assistance information, to shorten the cycle of the shortened DRX.

[0072] In this way, the terminal can lengthen the time of parsing the paging message in the connected state by shortening the cycle of the shortened DRX. Therefore, even if the terminal fails to synchronize in the idle state or the inactive state, the paging call can be successfully parsed in the connected state, the possibility of parsing the paging call is improved, and the call connection rate of the terminal is improved.

[0073] In some embodiments of the present application, the first information can include a first duration that the SSB SNR of the first cell is less than the first threshold value when the first terminal is in the idle state or the inactive state.

[0074] In some embodiments of the present application, the step 103 can further include the following step 103b.

[0075] Step 103b, in the case that the first duration reaches the first preset duration and the SSB SNR of the second cell is greater than or equal to the first threshold value, the first terminal accesses the second cell.

[0076] In some embodiments of the present application, in the case that the first information includes a first duration that the SSB SNR of the first cell is less than the first threshold value when the first terminal is in the idle state or the inactive state, the first terminal can obtain the SSB SNR of the neighbor cell of the first cell when the first duration reaches the first preset duration, and determine that the signal quality of the neighbor cell is good when the SSB SNR of the neighbor cell is greater than or equal to the first threshold value, so that the first terminal can access the neighbor cell, to avoid paging miss of the first terminal.

[0077] Exemplarily, the first threshold value is 50 dB, and the first duration is 8 s. If the first terminal detects that the SSB SNR of the first cell is less than 50 dB when the first terminal is in the idle state or the inactive state, and the duration reaches 8 s, and the SSB SNR of the neighbor cell of the first cell is 85 dB, the first terminal can access the neighbor cell of the first cell. That is, the first terminal can access the second cell.

[0078] In some embodiments of the present application, the first terminal can obtain the SSB SNR of the second cell through a management information base (MIB) message. In actual implementation, the first terminal can also obtain the SSB SNR of the second cell through other possible manners. The embodiments of the present application are not limited specifically.

[0079] In some embodiments of the present application, before accessing the neighbor cell, the first terminal can access the optimal neighbor cell as the second cell to be accessed, with reference to the RSRP, RSRQ signal quality and other indicators of the neighbor cell.

[0080] In some embodiments of the present application, the first preset duration can be default for the terminal, set by the user, or configured by the network side device. The embodiments of the present application are not limited specifically.

[0081] In this way, since the terminal can access the neighbor cell to avoid paging miss in the case that the SSB signal quality of the cell in which the terminal stays in the idle state or the inactive state is poor, the terminal parses the paging message in the neighbor cell, avoids parsing the paging message to fail, and thus improves the possibility of successful call establishment of the terminal and the call connection rate of the terminal.

[0082] In some embodiments of the present application, in the case that the first information includes the first duration in which the SSB SNR of the first cell is less than the first threshold value when the first terminal is in the idle state or the inactive state, the step 103 can further include the following step 103c.

[0083] The step 103c includes: in the case that the first duration reaches the first preset duration and the SSB SNR of the second cell is less than the first threshold value, the first terminal enters the connected state, or the period of the DRX is shortened.

[0084] In some embodiments of the present application, when the SSB SNR of the first cell is less than the first threshold for a long duration and the SSB SNR of the second cell is also poor when the first terminal is in the idle state or the deactivated state, the first terminal can determine that the signal quality of the first cell and its neighboring cells is poor at this time. If the first terminal is in the idle state or the deactivated state after accessing the first cell or its neighboring cells, it may cause paging miss. Therefore, the first terminal can directly enter the connected state, or shorten the DRX cycle to increase the time of the first terminal in the connected state to avoid parsing the paging message failure.

[0085] In this way, since the first terminal can select to enter the connected state or shorten the DRX cycle when the SSB signal quality of the cell accessed by the terminal or its neighboring cells is poor, the time of the first terminal in the connected state can be increased to avoid paging miss, thereby improving the possibility of successful establishment of the terminal call and improving the call connection rate of the terminal call.

[0086] In some embodiments of the present application, after the above step 103b, the communication method provided by the embodiments of the present application can further include the following step A or step B.

[0087] In step A, when the SSB SNR of the second cell is less than the first threshold when the first terminal is in the idle state or the deactivated state, if the TRS SNR of the second cell is greater than or equal to the second threshold when the first terminal is in the connected state, the first terminal shortens the DRX cycle.

[0088] In step B, when the SSB SNR of the second cell is less than the first threshold when the first terminal is in the idle state or the deactivated state, if the second duration that the SSB SNR of the second cell is less than the first threshold when the first terminal is in the idle state or the deactivated state reaches the second preset duration, the first terminal accesses the third cell.

[0089] The third cell can be a cell different from the second cell in the neighboring cells of the first cell.

[0090] In some embodiments of the present application, after accessing the second cell, if the SSB SNR of the second cell is also less than the first threshold when the first terminal is in the idle state or the deactivated state, the first terminal can avoid parsing the paging message failure by shortening the DRX cycle or by accessing other neighboring cells, thereby improving the possibility of successful establishment of the terminal call.

[0091] In some embodiments of the present application, the second preset duration can be default for the terminal, set by the user, or configured by the network side device. The embodiments of the present application do not make specific limitations.

[0092] In some embodiments of the present application, the second preset time length and the first preset time length can be the same or different. The embodiments of the present application do not make specific limitations.

[0093] It should be noted that the detailed description of step A above can refer to the related description in step 103a above; the detailed description of step B above can refer to the detailed description in step 103b above. To avoid repetition, this will not be repeated here.

[0094] In this way, since the terminal can shorten the DRX cycle after switching to the second cell, in the case that the SSB signal quality of the second cell is still poor when the terminal is in the idle state or the deactivated state, the time for the terminal to parse the paging in the connected state can be increased to avoid the terminal missing the paging; or the terminal can access other neighboring cells to avoid the terminal missing the paging. In this way, the possibility of successful call establishment of the terminal is improved, and the call connection rate of the terminal is improved.

[0095] Each of the above method embodiments, or each of the various possible implementation manners of the method embodiments, can be executed alone or in combination with any two or more of them, and the specific execution can be determined according to actual use requirements, and the embodiments of the present application do not make limitations in this regard.

[0096] The communication method provided by the embodiments of the present application will be exemplarily described below with specific examples.

[0097] Embodiment 1: As shown in FIG. 2, the communication method can include the following steps 201 to 203.

[0098] Step 201: The first terminal camps on the first cell.

[0099] Step 202: The first terminal records the TRS SNR of the first cell when the first terminal is in the connected state and the SSB SNR of the first cell when the first terminal is in the idle state or the deactivated state.

[0100] Step 203: When the SSB SNR of the first cell when the first terminal is in the idle state or the deactivated state is less than the first threshold value, and the TRS SNR of the first cell when the first terminal is in the connected state is greater than or equal to the second threshold value, the first terminal shortens the cycle of the DRX.

[0101] In this way, the first terminal can shorten the cycle of the DRX, thereby increasing the time for the terminal to parse the paging in the connected state, avoiding the terminal missing the paging, and improving the call connection rate of the terminal.

[0102] Embodiment 2: As shown in FIG. 3, the communication method can include the following steps 301 to 305.

[0103] Step 301: The first terminal camps on the first cell.

[0104] In step 302, the first terminal records the TRS SNR of the first cell when the first terminal is in the connected state and the SSB SNR of the first cell when the first terminal is in the idle state or the deactivated state.

[0105] In step 303, the first terminal determines whether the SSB SNR of the first cell when the first terminal is in the idle state or the deactivated state is less than a first threshold value and whether a first duration for which the SSB SNR of the first cell when the first terminal is in the idle state or the deactivated state is less than the first threshold value is greater than a first preset duration.

[0106] In step 304, the first terminal accesses a suboptimal second cell when the SSB SNR of the first cell when the first terminal is in the idle state or the deactivated state is less than the first threshold value and the first duration for which the SSB SNR of the first cell when the first terminal is in the idle state or the deactivated state is less than the first threshold value is greater than or equal to the first preset duration.

[0107] In step 305, the first terminal enters the connected state when the SSB SNR of the first cell when the first terminal is in the idle state or the deactivated state is greater than or equal to the first threshold value or the first duration for which the SSB SNR of the first cell when the first terminal is in the idle state or the deactivated state is less than the first threshold value is less than the first preset duration.

[0108] In this way, the first terminal can access a neighboring cell or enter the connected state to avoid terminal paging miss and improve the possibility of successful establishment of a terminal call, thereby improving the call connection rate of the terminal call.
