AI Technical Summary

Technical Problem

When switching between cells of different network standards, the UE needs to re-request the network to establish a default bearer, resulting in a large number of default bearer losses, especially when intercommunication is impossible when the N26 interface does not exist.

Method used

When the UE switches between different cells, the number of times the default bearer is lost is obtained. When the number of times the default bearer is lost reaches or exceeds a threshold, the corresponding cell is determined as a prohibited access cell to avoid further switching.

Benefits of technology

This effectively reduces the number of default bearer losses during inter-cell handovers between different network standards, ensuring that the UE always resides in a network with a good signal and avoiding the ping-pong effect.

[0001] Cross-reference to Related Applications

[0002] The present application claims priority to the Chinese patent application No. 202410423168.7 filed on April 9, 2024 in China, the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0003] The present application belongs to the field of communication technology, and particularly relates to a communication method and device, an electronic device, and a readable storage medium. BACKGROUND

[0004] Currently, the interworking of networks of different network modes is mainly through an N26 interface. When a user equipment (UE) switches between two cells of different network modes with an N26 interface, the UE does not need to request the network to re-establish a default bearer, that is, the default bearer between the two cells of different network modes will not be lost.

[0005] However, when the UE switches between two cells of different network modes without an N26 interface, since the two cells of different network modes cannot realize interworking through the N26 interface, the UE needs to request the network to establish a default bearer each time the UE switches between the two cells of different network modes, thereby causing a large number of losses of the default bearer. SUMMARY

[0006] Embodiments of the present application provide a communication method and device, an electronic device, and a readable storage medium, which can effectively reduce the number of losses of the default bearer.

[0007] In a first aspect, embodiments of the present application provide a communication method, which includes: in a case where a UE switches between a first cell and a second cell, obtaining a number of losses of a default bearer between the first cell and the second cell, the network mode of the first cell being different from the network mode of the second cell; and in a case where the number of losses is greater than or equal to a first threshold, determining the first cell or the second cell as a cell that is prohibited to access.

[0008] In a second aspect, embodiments of the present application provide a communication device, which includes an obtaining module and a determining module. The obtaining module is configured to, in a case where a UE switches between a first cell and a second cell, obtain a number of losses of a default bearer between the first cell and the second cell, the network mode of the first cell being different from the network mode of the second cell. The determining module is configured to, in a case where the number of losses is greater than or equal to a first threshold, determine the first cell or the second cell as a cell that is prohibited to access.

[0009] In a third aspect, an electronic device is provided, which includes a processor and a memory. The memory stores programs or instructions executable on the processor. The programs or instructions, when executed by the processor, implement the steps of the method according to the first aspect.

[0010] In a fourth aspect, a readable storage medium is provided, which stores programs or instructions. The programs or instructions, when executed by a processor, implement the steps of the method according to the first aspect.

[0011] In a fifth aspect, a chip is provided, which includes a processor and a communication interface. The communication interface is coupled to the processor. The processor is configured to execute programs or instructions to implement the method according to the first aspect.

[0012] In a sixth aspect, a computer program / program product is provided, which is stored in a storage medium. The computer program / program product is executed by at least one processor to implement the method according to the first aspect.

[0013] In the embodiments of the present application, in the case that the UE switches between the first cell and the second cell, the number of losses of the default bearer between the first cell and the second cell can be obtained, the network mode of the first cell is different from the network mode of the second cell; and in the case that the number of losses is greater than or equal to a first threshold, the first cell or the second cell is determined as a forbidden access cell. Through the scheme, when the number of losses of the default bearer between the first cell and the second cell is greater than or equal to the first threshold, the UE can be forbidden to access the first cell or the second cell, so that the UE can always camp in the network corresponding to the second cell, or can no longer attempt to switch from the first cell to the second cell. In this way, the loss of the default bearer when switching between the first cell and the second cell can be avoided, and the number of losses of the default bearer when switching between cells of different network modes can be effectively reduced.

[0023] The technical solutions in the embodiments of the present application will be clearly described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some, but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art belong to the scope of protection of the present application.

[0024] The terms "first", "second", and the like in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the terms used in this way can be interchanged under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than that illustrated or described herein, and the objects distinguished by "first", "second", etc. are generally a category, not limited to the number of objects, for example, the first object can be one or more. In addition, "and / or" in the specification and claims means at least one of the connected objects, and the character " / ", generally indicates that the objects before and after are in an "or" relationship.

[0025] The terms "at least one", "at least one of", and the like in the specification and claims of the present application refer to any one of the objects, a combination of any two or more of the objects. For example, at least one of a, b, and c can mean "a", "b", "c", "a and b", "a and c", "b and c", and "a, b, and c", where a, b, and c can be single or multiple. Similarly, "at least two" refers to two or more, and has a similar meaning to "at least one".

[0026] The communication method, apparatus, electronic device, and readable storage medium provided by the embodiments of the present application will be described in detail below with reference to the drawings and specific embodiments and application scenarios.

[0027] New Radio (NR) is the current 5G technology, and Long Term Evolution (LTE) is the last generation 4G technology. Currently, the operator's circuit switched (CS) network is gradually retired to build more 4G networks and 5G networks. Through the combination of 4G networks and 5G networks, a better communication experience can be created for users.

[0028] Currently, the interworking of networks of different network standards is mainly through the N26 interface. For example, taking 4G networks and 5G networks as an example, through the N26 interface, the UE can keep the Internet Protocol (IP) address consistent between the 4G network and the 5G network. In the scenario where the N26 interface exists, the UE establishes a default bearer after camping on a 5G cell or a 4G cell, and the network will configure the default bearer mapping of the 5G cell or the 4G cell. Through this mapping relationship, when the UE switches from a 5G cell to a 4G cell or from a 4G cell to a 5G cell, there is no need to request the network to establish a default bearer again, and the network can successfully obtain the relevant context information.

[0029] However, in the current network, there are 4G cells without N26 interfaces and 5G cells with N26 interfaces. In this scenario, when the UE switches from a 5G cell to a 4G cell, the network cannot obtain the relevant context information, and cannot successfully map the bearer, so that the UE will request the network to establish a default bearer again after camping on the 4G cell. When the UE switches from a 4G cell to a 5G cell, the UE will delete the local default bearer, and then request the network to establish a default bearer again after camping on the 5G cell.

[0030] Exemplarily, as shown in FIG. 1, for X province, the 4G core network and the 5G core network have the N26 interface, and the 5G cells and the 4G cells of X province can normally interwork, and can successfully map the bearer when switching cells, without the need to separately request the network to establish a default bearer again. However, for the boundary cell 5G cell 2 and the 4G cell 5 of X province and Y province, since there is no N26 interface between the 5G core network of X province and the 4G core network of Y province, the 5G cells and the 4G cells of X province cannot normally interwork, and cannot successfully map the bearer when switching cells, and need to request the network to establish a default bearer again.

[0031] As can be seen from the above, when the UE switches between the 5G cell and the 4G cell without the N26 interface, since the 5G cell and the 4G cell cannot interwork through the N26 interface, the UE needs to request the network to establish a default bearer again every time the UE switches between the 5G cell and the 4G cell, thereby causing a large number of losses of the default bearer.

[0032] To solve the above problems, the embodiment of the present application provides a communication method, a device, an electronic device and a readable storage medium. The communication method provided by the embodiment of the present application can be applied in the scene of efficient packet switching frame buffer (EPSFB) call, or the scene of interworking between 5G cells without N26 interface and 4G cells, or the scene of interworking between 5G cells with N26 interface and 4G cells without N26 interface, etc.

[0033] Exemplarily, taking the scene of interworking between 5G cells without N26 interface and 4G cells as an example, in the communication method provided by the embodiment of the present application, in the case that the UE switches between the 5G cell and the 4G cell, the loss number of the default bearer between the 5G cell and the 4G cell can be acquired; and in the case that the loss number is greater than or equal to a first threshold, the 5G cell or the 4G cell is determined as a cell prohibited to be accessed. Through the scheme, when the loss number of the default bearer between the 5G cell and the 4G cell is greater than or equal to the first threshold, the UE can prohibit to access the 5G cell or the 4G cell, so that the UE can always camp in the network corresponding to the 4G cell, or can no longer attempt to switch from the 5G cell to the 4G cell. In this way, the loss of the default bearer when switching between the 5G cell and the 4G cell can be avoided, and the loss number of the default bearer when switching between cells of different network types can be effectively reduced.

[0034] It should be noted that the execution subject of the communication method provided by the embodiment of the present application can be a communication device, a UE or a functional module in the UE, etc. In some embodiments of the present application, the UE executes the communication method as an example to illustrate the communication method provided by the embodiment of the present application.

[0035] FIG. 2 shows a flowchart of the communication method provided by the embodiment of the present application. As shown in FIG. 2, the communication method provided by the embodiment of the present application can include the following steps 201 and 202.

[0036] Step 201: In the case that the UE switches between a first cell and a second cell, the UE acquires the loss number of the default bearer between the first cell and the second cell.

[0037] Wherein, the network type of the first cell is different from the network type of the second cell.

[0038] Exemplarily, the first cell can be a 5G cell, and the second cell can be a 4G cell; or the first cell can be a 4G cell, and the second cell can be a 5G cell, etc.

[0039] Optionally, in the embodiments of the present application, the switching of the UE between the first cell and the second cell can include at least one of the following: switching of the UE from the first cell to the second cell, and switching of the UE from the second cell to the first cell.

[0040] It should be noted that the default bearer is a bearer established by the system itself when the UE and the network complete attachment, and no other data transmission is performed. When the UE has a small amount of data transmission, the data can be directly transmitted on the default bearer. The data transmitted on the default bearer can be understood as a small amount of data directly transmitted on a public channel.

[0041] In the embodiments of the present application, the first cell and the second cell can be two cells that cannot be interconnected through an N26 interface. When the UE switches from the first cell to the second cell or from the second cell to the first cell, the default bearer between the first cell and the second cell corresponding to the UE is lost.

[0042] Optionally, in the embodiments of the present application, the first cell and the second cell can be cells at the boundary of a core network.

[0043] Optionally, in the embodiments of the present application, the loss of the default bearer means that the UE deletes the local default bearer. At this time, a new default bearer needs to be requested to be established by the network.

[0044] Optionally, in the embodiments of the present application, the UE can perform counting on the number of times of loss of the default bearer between the first cell and the second cell to obtain the number of times of loss.

[0045] Optionally, in the embodiments of the present application, the UE can add 1 to the number of times of loss each time the default bearer between the first cell and the second cell is lost, to realize counting on the number of times of loss of the default bearer.

[0046] It can be understood that the number of times of loss is the cumulative number of times of loss of the default bearer.

[0047] For example, it is assumed that the UE currently resides in the first cell. When the UE switches from the first cell to the second cell for the first time, if the default bearer between the first cell and the second cell is lost, the UE can record the number of times of loss of the default bearer as 1. When the UE switches from the first cell to the second cell again, if the default bearer between the first cell and the second cell is lost, the UE can add 1 to the number of times of loss and record the number of times of loss of the default bearer as 2. In this way, the number of times of loss can be obtained.

[0048] In step 202, the UE determines the first cell or the second cell as a cell that is prohibited to access when the number of times of loss is greater than or equal to a first threshold.

[0049] In the embodiments of the present application, the loss times are the loss times of the default bearers between the first cell and the second cell.

[0050] Optionally, in the embodiments of the present application, the first threshold value can be configured by a network or determined by the UE itself.

[0051] Optionally, in the embodiments of the present application, the first threshold value can be any threshold value such as 1, 5 or 10, which can be determined according to actual use requirements, and the embodiments of the present application are not limited in this way.

[0052] Optionally, in the embodiments of the present application, the UE determines the first cell or the second cell as a cell which is prohibited to access, which can be understood as that the UE disables the first cell or the second cell.

[0053] For example, when the loss times are greater than or equal to the first threshold value, the UE can add the related information of the first cell to a list of cells which are prohibited to access in the UE, so as to determine the first cell as a cell which is prohibited to access. In this way, the UE will not access the first cell until the UE cancels the determination of the first cell as a cell which is prohibited to access.

[0054] Optionally, in the embodiments of the present application, when the signal quality of the first cell is greater than or equal to a signal quality threshold value, the loss times can include the loss times of the default bearers when switching from the first cell to the second cell. For example, as shown in FIG. 3, the step 202 can be implemented by the step 202a or the step 202b.

[0055] Optionally, in the embodiments of the present application, the signal quality threshold value can be configured by a network or determined by the UE itself.

[0056] Optionally, in the embodiments of the present application, when the signal quality of the first cell is greater than or equal to the signal quality threshold value, it can be considered that the signal quality of the first cell is good.

[0057] The step 202a includes: when the loss times are greater than or equal to the first threshold value and there is a target cell, the UE determines the second cell as a cell which is prohibited to access.

[0058] The network standard of the target cell is the same as that of the second cell, and the default bearers between the first cell and the target cell are not lost when switching from the first cell to the target cell.

[0059] For example, if the second cell is a 4G cell, the target cell is also a 4G cell; if the second cell is a 5G cell, the target cell is also a 5G cell.

[0060] Optionally, in the embodiment of the present application, the first cell and the target cell can interwork through an N26 interface, so that the default bearer between the first cell and the target cell is not lost when switching from the first cell to the target cell, that is, there is no need to request the network to reestablish the default bearer.

[0061] Optionally, in the embodiment of the present application, the first cell can be a cell in which the UE is currently camped.

[0062] Optionally, in the embodiment of the present application, when the target cell exists, the UE can switch from the first cell to the target cell to realize the switching between cells of different network types, for example, the cell switching in the EPS FB call scenario; at this time, the UE can determine the second cell as a cell that is prohibited to access, and prohibit switching from the first cell to the second cell again, so as to reduce the loss times of the default bearer.

[0063] In step 202b, when the loss times are greater than or equal to the first threshold and the target cell does not exist, the UE determines the first cell as a cell that is prohibited to access.

[0064] Optionally, in the embodiment of the present application, after the UE determines the first cell as a cell that is prohibited to access, the UE can camp in the network corresponding to the second cell and continue to perform the switching between cells of different network types in the network; so as to prohibit switching from the second cell to the first cell again, so as to reduce the loss times of the default bearer.

[0065] Optionally, in the embodiment of the present application, when the loss times are greater than or equal to the first threshold, the UE can first detect whether the target cell exists, and then determine the first cell or the second cell as a cell that is prohibited to access according to the detection result.

[0066] For example, if the first cell is a 5G cell and the second cell is a 4G cell, then:

[0067] 1. After the UE camps in the 5G cell, the network can establish an IP multimedia system (IP Multimedia Subsystem, IMS) bearer or a data default bearer, and configure the mapping between the 4G network and the 5G network, at this time, the UE can only interwork and switch with the 4G cell having an N26 interface with the 5G cell;

[0068] 2、When the signal quality of the 5G cell is good, if the network initiates an EPS FB call, the UE will attempt to switch to a 4G cell; if the UE switches to a 4G cell that has an N26 interface with the 5G cell, the UE will normally bear on the 4G cell, and at this time, the information of the 5G cell and the 4G cell of the normal EPS FB call is recorded; if the UE switches to a 4G cell that does not have an N26 interface with the 5G cell, for example, the second cell, the UE will lose the default bearer on the 4G cell, and at this time, the information of the 5G cell and the 4G cell of the failed EPS FB call is recorded, and the number of times of default bearer loss corresponding thereto is recorded;

[0069] 3、If the EPS FB call fails multiple times, the UE records that the number of times of default bearer loss exceeds a threshold Threshold 5T4PDPLOSS, for example, the first to the third thresholds, if there is a normal 4G cell when switching from the 5G cell to the 4G cell, that is, the target cell, the UE can permanently disable the abnormal 4G cell, so that the UE can normally perform the EPS FB call and switch to the normal 4G cell in the future; otherwise, the UE can disable the 5G abnormal cell (including permanently disabling or disabling for a period of time), so that the UE will camp on the current 4G cell outside the core network in the future, and then perform a 4G VoLTE call.

[0070] In the embodiments of the present application, when the number of times of default bearer loss when switching from the first cell to the second cell is greater than or equal to the first threshold, the UE can determine the first cell or the second cell as a cell to be prohibited from accessing according to whether the target cell exists, so that the number of times of default bearer loss can be reduced while ensuring normal execution of UE services.

[0071] Optionally, in the embodiments of the present application, in the case where the signal quality of the first cell is less than a signal quality threshold, the number of times of loss can include: a first number of times of loss of the default bearer when switching from the first cell to the second cell, and a second number of times of loss of the default bearer when switching from the second cell to the first cell; and the first threshold can include a second threshold and a third threshold. For example, as shown in FIG. 4, the step 202 can be implemented by the following step 202c in combination with FIG. 2.

[0072] Optionally, in the embodiments of the present application, when the signal quality of the first cell is less than the signal quality threshold, the signal quality of the first cell can be considered to be poor.

[0073] In the step 202c, if the first number of times of loss is greater than or equal to the second threshold, and the second number of times of loss is greater than or equal to the third threshold, and the signal quality of the first cell is less than or equal to a fourth threshold, the UE determines the first cell as a cell to be prohibited from accessing.

[0074] Optionally, in embodiments of the present application, the second threshold value can be configured by the network or determined by the UE itself.

[0075] Optionally, in embodiments of the present application, the second threshold value can be determined according to a signal quality parameter of the first cell, which can include but is not limited to at least one of the following: Reference Signal Receiving Power (RSRP), Signal to Interference plus Noise Ratio (SINR), Reference Signal Receiving Quality (RSRQ), Received Signal Strength Indicator (RSSI), etc.

[0076] For example, taking the case where the second threshold value is determined according to the RSRP of the first cell as an example, the second threshold value can be an RSRP threshold value; and the signal quality of the first cell being less than or equal to the second threshold value can be understood as the RSRP of the first cell being less than or equal to the RSRP threshold value.

[0077] For another example, taking the case where the second threshold value is determined according to the SINR of the first cell as an example, the second threshold value can be an SINR threshold value; and the signal quality of the first cell being less than or equal to the second threshold value can be understood as the SINR of the first cell being less than or equal to the SINR threshold value.

[0078] Optionally, in embodiments of the present application, the third threshold value can be configured by the network or determined by the UE itself.

[0079] Optionally, in embodiments of the present application, the second threshold value and the third threshold value can be the same or different.

[0080] Optionally, in embodiments of the present application, the fourth threshold value can be configured by the network or determined by the UE itself.

[0081] Optionally, in embodiments of the present application, the fourth threshold value can be less than the signal quality threshold value, i.e., when the signal quality of the first cell is less than or equal to the fourth threshold value, it can be considered that the signal quality of the first cell is worse than the signal quality threshold value.

[0082] Optionally, in the embodiments of the present application, the UE can record the first loss number and the second loss number respectively; that is, when the UE switches from the first cell to the second cell, the UE can add 1 to the first loss number each time the default bearer is lost, and when the UE switches from the second cell to the first cell, the UE can add 1 to the second loss number each time the default bearer is lost.

[0083] For example, assuming that the first cell is a 5G cell and the second cell is a 4G cell, then:

[0084] 1. After the UE camps on the 5G cell, the network can establish an IMS bearer or a data default bearer and configure the mapping between the 4G network and the 5G network, at this time the UE can only interwork with the 4G cell that has an N26 interface with the 5G cell for interworking switching;

[0085] 2. When the signal quality of the 5G cell is poor, the network will try to switch the UE to the 4G cell, if there is no N26 interface between the 4G cell and the 5G cell, the 4G cell will delete the default bearer of the UE, at this time the UE needs to record the abnormal cell information and the default bearer loss number when switching from the 5G cell to the 4G cell, for example, the first loss number; then after the UE camps on the 4G cell, it can request the establishment of the default bearer again, the UE will search for the 5G cell on the 4G cell, or the network will let the UE search for the 5G cell regularly, when the UE detects that the signal of the 5G cell is better than the network threshold, the UE will try to register the 5G cell again, at this time the default bearer will also be lost, and the UE needs to record the abnormal cell information and the default bearer loss number when switching from the 4G cell to the 5G cell, for example, the second loss number;

[0086] 3. If the UE detects that the number of default bearer losses when switching between the abnormal 5G cell and the abnormal 4G cell is greater than or equal to the corresponding threshold, and the signal quality of the 5G cell is worse than the network threshold, the UE can disable (including permanently disable or disable for a period of time) the 5G cell; in this way, the UE can remain on the 4G cell and avoid ping-pong and default bearer loss.

[0087] In the embodiments of the present application, when the first loss number is greater than or equal to the second threshold, the second loss number is greater than or equal to the third threshold, and the signal quality of the first cell is poor, the UE can disable the first cell, so that the first cell can be disabled only when the default bearer is lost frequently and the network quality of the first cell is poor. Thus, the first cell can be reasonably triggered to be disabled to avoid ping-pong and default bearer loss between the first cell and the second cell.

[0088] Optionally, in the embodiments of the present application, as shown in Figure 5, the cell determining method provided by the embodiments of the present application can further comprise the following steps A and B after step 202c.

[0089] Step A: in the case that the UE camps on the second cell, the UE uses the network corresponding to the second cell within a first time duration.

[0090] The first time duration is a preset time duration starting from a first time point, and the first time point is the starting time point of the UE camping on the second cell.

[0091] Optionally, in the embodiments of the present application, the preset time duration can be 1 minute, 5 minutes, 10 minutes or any other time duration.

[0092] For example, taking the preset time duration of 5 minutes as an example, the UE can use the network corresponding to the second cell within 5 minutes starting from the starting time point of camping on the second cell.

[0093] Step B: after the first time duration, the UE detects the signal quality of the first cell, and in the case that the signal quality of the first cell is greater than a fourth threshold, the first cell is determined as a cell allowed to be accessed.

[0094] It can be understood that when the signal quality of the first cell is greater than the fourth threshold, it can be considered that the signal quality of the first cell is good, at this time, the first cell can be determined as a cell allowed to be accessed instead of a cell forbidden to be accessed, and the UE can continue to access the first cell.

[0095] In the embodiments of the present application, since the UE can determine the first cell as a cell allowed to be accessed in the case that the signal quality of the first cell is greater than the fourth threshold after using the network corresponding to the second cell for the first time duration, the flexibility of determining whether to continue to forbid the first cell can be improved according to the change of the signal quality of the first cell, thereby improving the flexibility of determining the forbidden cell.

[0096] Optionally, in the embodiments of the present application, as shown in Figure 6, the step 202 can be implemented by the following step 202d or step 202e.

[0097] Step 202d: in the case that the number of losses is greater than or equal to the first threshold, the UE determines the first cell or the second cell as a cell forbidden to be accessed within a second time duration.

[0098] The second time duration is a preset time duration starting from a second time point, and the second time point is the time point at which the number of losses is greater than or equal to the first threshold.

[0099] Optionally, in the embodiments of the present application, the preset time length can be any time length such as 3 minutes, 7 minutes or 25 minutes.

[0100] For example, taking the preset time length of 7 minutes as an example, the UE can determine the first cell or the second cell as the cell forbidden to access within 7 minutes from the time when the number of times of loss is greater than or equal to the first threshold.

[0101] Step 202e, in the case that the number of times of loss is greater than or equal to the first threshold, the UE determines the first cell or the second cell as the cell permanently forbidden to access.

[0102] Optionally, in the embodiments of the present application, the UE can add the cell information of the first cell or the cell information of the second cell to the list of cells permanently forbidden to access in the UE, so as to permanently forbid the first cell or the second cell.

[0103] For example, taking the case that the UE determines the first cell as the cell permanently forbidden to access as an example, after the UE determines the first cell as the cell permanently forbidden to access, the UE will not access the first cell permanently until the cell information of the first cell is deleted from the list of cells permanently forbidden to access.

[0104] In the embodiments of the present application, since the UE can determine the first cell or the second cell as the cell forbidden to access for a period of time or can permanently determine the first cell or the second cell as the cell forbidden to access, the flexibility of determining the cell forbidden to access can be improved, so as to flexibly determine the first cell or the second cell as the cell forbidden to access in different network environments.

[0105] In the communication method provided by the embodiments of the present application, when the number of times of loss of the default bearer between the first cell and the second cell is greater than or equal to the first threshold, the UE can forbid to access the first cell or the second cell, so that the UE can always camp in the network corresponding to the second cell or can no longer attempt to switch from the first cell to the second cell. In this way, the loss of the default bearer when switching between the first cell and the second cell can be avoided, and the number of times of loss of the default bearer when switching between cells of different network modes can be effectively reduced.

[0106] The various possible implementation manners in the method embodiments can be executed independently, or, in the absence of contradiction, can also be executed in combination, and the specific execution can be determined according to actual use requirements, and the embodiments of the present application do not limit this.

[0107] The execution subject of the communication method provided by the embodiments of the present application can be a communication device. In the embodiments of the present application, the communication device executing the communication method is taken as an example to illustrate the communication device provided by the embodiments of the present application.

[0108] As shown in FIG. 7, the embodiment of the present application provides a communication apparatus 70, which can include an obtaining module 71 and a determining module 72.

[0109] The obtaining module 71 can be configured to obtain a number of losses of a default bearer between a first cell and a second cell in a case that the UE switches between the first cell and the second cell, wherein a network type of the first cell is different from a network type of the second cell. The determining module 72 can be configured to determine the first cell or the second cell as a forbidden access cell in a case that the number of losses is greater than or equal to a first threshold.

[0110] In a possible implementation, in a case that a signal quality of the first cell is greater than or equal to a signal quality threshold, the number of losses can include a number of losses of the default bearer when switching from the first cell to the second cell. The determining module 72 can be specifically configured to determine the second cell as the forbidden access cell in a case that there is a target cell, or determine the first cell as the forbidden access cell in a case that there is no target cell, wherein a network type of the target cell is the same as the network type of the second cell, and the default bearer between the first cell and the target cell is not lost when switching from the first cell to the target cell.

[0111] In a possible implementation, in a case that the signal quality of the first cell is less than the signal quality threshold, the number of losses can include a first number of losses of the default bearer when switching from the first cell to the second cell, and a second number of losses of the default bearer when switching from the second cell to the first cell, and the first threshold can include a second threshold and a third threshold. The determining module 72 can be specifically configured to determine the first cell as the forbidden access cell in a case that the first number of losses is greater than or equal to the second threshold, the second number of losses is greater than or equal to the third threshold, and the signal quality of the first cell is less than or equal to a fourth threshold.

[0112] In a possible implementation, the communication apparatus 70 can further include a using module and a processing module. The using module can be configured to use a network corresponding to the second cell within a first time length in a case that the determining module 72 determines the first cell as the forbidden access cell and the UE camps on the second cell, the first time length being a preset time length starting from a first time point, and the first time point being a starting time point of the UE camping on the second cell. The processing module can be configured to detect the signal quality of the first cell after the first time length, and determine the first cell as an allowed access cell in a case that the signal quality of the first cell is greater than the fourth threshold.

[0113] In a possible implementation, the determining module 72, in particular, can be configured to: determine the first cell or the second cell as a cell that is forbidden to access in a second time length, the second time length being a preset time length starting from a second time point, the second time point being a time point at which the number of losses is greater than or equal to the first threshold; or determine the first cell or the second cell as a cell that is permanently forbidden to access.

[0114] In the communication apparatus provided in the embodiments of the present application, when the number of losses of the default bearer between the first cell and the second cell is greater than or equal to the first threshold, the communication apparatus can forbid access to the first cell or the second cell, so that the UE can always camp on the network corresponding to the second cell, or can no longer attempt to switch from the first cell to the second cell. In this way, the loss of the default bearer when switching between the first cell and the second cell can be avoided, and the number of losses of the default bearer when switching between cells of different network modes can be effectively reduced.

[0123] The processor 1010 can be configured to, in a case where the UE switches between a first cell and a second cell, the network type of the first cell being different from the network type of the second cell, acquire a loss number of a default bearer between the first cell and the second cell, and in a case where the loss number is greater than or equal to a first threshold, determine the first cell or the second cell as a cell prohibited to access.

For example, the processor 1010 can be configured to, in a case where there is a target cell, determine the second cell as a cell prohibited to access, or in a case where there is no target cell, determine the first cell as a cell prohibited to access. The network type of the target cell is the same as the network type of the second cell, and the default bearer between the first cell and the target cell is not lost when switching from the first cell to the target cell.

[0127] In a possible implementation, the processor 1010 can be specifically configured to: determine the first cell or the second cell as a cell that is prohibited to access within a second time length, the second time length being a preset time length starting from a second time point, and the second time point being a time point at which the number of losses is greater than or equal to the first threshold; or determine the first cell or the second cell as a cell that is permanently prohibited to access.

[0128] In the electronic device provided in the embodiments of the present application, when the number of losses of the default bearer between the first cell and the second cell is greater than or equal to the first threshold, the electronic device can prohibit access to the first cell or the second cell, so that the UE can always camp in a network corresponding to the second cell, or can no longer attempt to switch from the first cell to the second cell. In this way, the loss of the default bearer when switching between the first cell and the second cell can be avoided, and the number of losses of the default bearer when switching between cells of different network modes can be effectively reduced.
