Detailed ways

The technical solutions in the embodiments of the present application will be clearly described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, but not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art fall within the scope of protection of this application.

The terms "first", "second", etc. in the description and claims of this application are used to distinguish similar objects and are not used to describe a specific order or sequence. It is to be understood that the figures so used are interchangeable under appropriate circumstances so that the embodiments of the present application can be practiced in sequences other than those illustrated or described herein, and that "first,""second," etc. are distinguished Objects are usually of one type, and the number of objects is not limited. For example, the first object can be one or multiple. In addition, the instructions and rights The "and/or" in the requirement indicates at least one of the connected objects. The character "/" generally indicates that the related objects are in an "or" relationship.

To facilitate understanding, some contents involved in the embodiments of the present application are described below.

With the development and acceleration of 5G network construction, operators' wireless spectrum resources are becoming increasingly tight. In order to solve the problem of operators' shortage of wireless spectrum resources, the trend of operators sharing networks is becoming more and more obvious. Operators can enhance network coverage and reduce network deployment costs by borrowing shared networks. Specifically, operators can realize network sharing through shared base stations or shared cells.

In the embodiment of this application, the shared cell can be connected to the NSA as an anchor cell. The anchor cell is a dual-connection cell that supports Long Term Evolution (LTE) technology and New Radio (NR) technology. Therefore, the shared cell may also be called a shared anchor cell.

When operators deploy networks, they can try to connect terminals to 5G based on the 5G support capabilities of terminal equipment. When the terminal device turns on the 5G capability and reports the 5G capability to the cell in which it is registered, the following situations may occur: 1) If the terminal device is registered in a shared anchor cell, the shared anchor cell does not configure the non-shared anchor cell. Measurement makes it impossible for terminal devices to escape from the shared anchor cell. 2) The terminal device is registered in the non-shared anchor cell. It is easier for the terminal to switch to the shared anchor cell if the non-shared anchor cell is configured. When the terminal turns off the 5G capability, it is easier for the terminal device to register with the non-shared anchor cell.

To facilitate understanding, the examples are as follows:

For the scenario where the terminal device turns on 5G, the terminal device can register in the shared anchor cell A and connect to the NSA's 5G cell C through the secondary cell group (Secondary Cell Group, SCG) connection. Cell A does not configure the measurement of non-shared anchor cell B, but only configures 5G SCG measurement.

For the scenario where the terminal device turns off 5G, the terminal device can be registered in the non-shared anchor cell B. The cell B network does not configure the measurement of shared anchor cell A.

It can be seen that when the 5G capability is turned on, the terminal device is easy to register to the shared anchor cell; when the 5G capability is turned off, the terminal device is easy to escape the shared anchor cell and register to the non-shared anchor cell.

After the terminal device registers in the shared anchor cell, it can use the shared anchor cell to connect to the NSA. However, with the accelerated deployment of SA networks and the gradual reduction of NSA, there may be situations where the shared anchor cell cannot access the NSA. On the other hand, some shared networks will limit shared resources, usually Limit the scheduling bandwidth of shared terminal equipment. For example, less than 20% of resources will be scheduled as shared resources. In this way, if the terminal device cannot use the shared cell to access the NSA and the scheduling resources are limited, abnormal problems such as low speed, Internet lag, and interruption will occur, resulting in poor communication quality.

In order to make terminal equipment communicate more smoothly in the shared network area and improve the communication quality of the terminal equipment, embodiments of the present application provide a cell selection method. When the terminal equipment turns on the 5G capability, it registers to the shared cell but is not connected to the 5G secondary cell group. In this case, the target operation can be performed according to the processing policy corresponding to the shared cell, so that the terminal device can register to a cell with better communication quality. In this way, the terminal device can escape from the shared cell that cannot access the NSA, thereby improving the communication stability of the terminal device and thereby improving the communication quality of the terminal device.

The cell selection method provided by the embodiments of the present application will be described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios.

Figure 1 is one of the flow charts of the cell selection method provided by the embodiment of the present application. The cell selection method provided by the embodiment of the present application can be applied to terminal equipment. In practical applications, the terminal equipment can be a mobile phone, a computer or a mobile station.

As shown in Figure 1, the cell selection method may include:

Step 101: When the terminal device turns on the 5G capability and registers with the first cell but is not connected to the 5G secondary cell group, obtain the processing policy corresponding to the first cell, where the first cell is a shared cell of at least two operators. ; The processing strategy corresponding to the first cell includes at least one of the following: disabling the first cell, and turning off the 5G capability of the terminal device registered to the first cell.

In this embodiment of the present application, the first cell is a shared cell of at least two operators. After registering to the first cell, the terminal device can connect to the 5G SCG through the first cell. Therefore, it is understandable that the first cell can be the aforementioned shared anchor cell.

The terminal device turns on the 5G capability and registers with the first cell. Specifically, the terminal device can enable 5G capabilities and report the 5G capabilities to the network. The network can configure the terminal device to register with the first cell by querying the 5G capabilities of the terminal device. The terminal device can determine whether to register for the shared anchor cell by using the Public Land Mobile Network (PLMN) to identify whether the operator to which it belongs and the operator to which the registered frequency point belongs are the same operator. If not, it can be determined Register to share Anchor neighborhood.

It can be understood that the terminal device is any terminal device registered in the first cell.

The terminal device is not connected to the 5G secondary cell group, which means: the terminal device is not connected to the NSA's 5G network. In one implementation, the terminal device can determine whether to connect to the 5G SCG by detecting whether it displays the Evolved Universal Terrestrial Radio Access Network-New Radio Dual Connectivity (E-UTRAN-NR Dual Connectivity, ENDC) logo. If the ENDC logo is displayed, it is sure to be connected to the 5G SCG; if the ENDC logo is not displayed, it is sure to be not connected to the 5G SCG.

In this case, if the terminal device continues to reside in the first cell, it will be unable to connect to the 5G network, which may cause communication abnormalities. Therefore, in order to ensure communication fluency of the terminal device, the terminal device can be allowed to escape from the first cell and register in the target cell.

In this embodiment of the present application, the terminal device can obtain the processing policy corresponding to the first cell, perform the target operation according to the processing policy, escape the first cell, and register to the target cell.

In some embodiments, the processing policy corresponding to the first cell may be sent by the server to the terminal device, and the terminal device may receive and obtain the processing policy corresponding to the first cell. The server may determine the processing strategy corresponding to the first cell based on the latest collected number of abnormal events in the first cell within a preset time period. In this way, the processing strategy corresponding to the first cell can be matched with the current situation of the first cell, thereby improving the reliability of communication processing.

In other embodiments, the processing policy corresponding to the first cell may be predefined in the protocol, and the terminal device may obtain the processing policy corresponding to the first cell by reading the protocol. In this way, the terminal device does not need to interact with other devices to obtain the processing policy, thereby saving signaling overhead.

The processing strategy of disabling the first cell means that the terminal device can escape from the first cell and register to other shared cells to improve the communication quality of the terminal device.

The processing strategy of turning off the 5G capabilities of terminal devices registered in the first cell indicates that there is a problem with the network in the shared network area. Even if the terminal device escapes the first cell and registers in other shared cells, the communication quality of the terminal device cannot be improved. Therefore, , the terminal device can turn off the 5G function and register to a non-shared cell to improve the communication quality of the terminal device.

Step 102: According to the processing policy, perform the target operation so that the terminal device registers in the target cell. Wherein, the communication quality of the terminal device in the target cell is higher than the communication quality of the terminal device in the first cell.

In this embodiment of the present application, the target operation may include at least one of the following: disabling the first cell; turning off the 5G function of the terminal device.

The specific target operation performed by the terminal device can be determined based on the specific performance of the processing policy.

In the case where the processing policy only includes disabling the first cell, the terminal device can disable the first cell and register to the second cell to improve the communication quality of the terminal device. In this case, the target operation is to disable the first cell and the target cell is the second cell. Since the 5G function of the terminal equipment is still turned on at this time, it can be seen from the above content that the probability of the second cell being a shared cell is relatively high.

In the case where the processing policy only includes turning off the 5G capability of the terminal device registered to the first cell, the terminal device can turn off the 5G function of the terminal device and register to the third cell to improve the communication quality of the terminal device. In this case, the target operation is to turn off the 5G function of the terminal device, and the target cell is the third cell. Since the 5G function of the terminal equipment is turned off at this time, it can be seen from the above content that the probability of the second cell being a non-shared cell is relatively high.

In the case where the processing strategy includes disabling the first cell and turning off the 5G capability of the terminal device registered to the first cell, in one implementation, the terminal device can first disable the first cell and register to the second cell; then, the terminal device can Detect whether the communication quality of the first terminal in the second cell reaches the preset indicator; if it reaches the preset indicator, it can stay in the second cell; if it does not, the 5G function of the terminal device can be turned off and registered in the third cell. community. In another implementation, the terminal device can directly turn off the 5G function of the terminal device and register to the third cell.

According to the cell selection method of the embodiment of the present application, when the terminal device turns on the 5G capability and registers in the shared cell but is not connected to the 5G secondary cell group, the target operation can be performed according to the processing policy corresponding to the shared cell, so that the terminal device Register to a community with better communication quality. In this way, the terminal device can escape from the shared cell that cannot access the NSA, thereby improving the communication stability of the terminal device and thereby improving the communication quality of the terminal device.

In this embodiment, the resource scheduling situation of the terminal device may be: resource scheduling is abnormal; or resource scheduling is normal.

The resource scheduling situation of the terminal device can be characterized by at least one of the following:

The amount of uplink data received by the terminal device within a certain period of time;

The amount of downlink data received by the terminal device within a certain period of time;

The delay of the Transmission Control Protocol (TCP) packet of the terminal device.

When at least one of the following conditions is met, it can be determined that the resource scheduling of the terminal device is abnormal:

The amount of downlink data is less than or equal to the downlink data threshold;

The delay of the TCP packet is greater than the delay threshold.

The communication status of the terminal device can be manifested as: abnormal communication; or normal communication.

The communication situation of the terminal device can be characterized by at least one of the following:

The number of freezes is greater than the freeze count threshold;

The number of network disconnections is greater than the network disconnection count threshold.

The available neighbor cells of the terminal device can be expressed as: the terminal device has available neighbor cells; or the terminal device does not have available neighbor cells.

In this embodiment, the terminal device can further combine one or more of the above conditions of the terminal device to perform the target operation on the basis of the processing strategy, so that the performed target operation can be more in line with the actual needs of the terminal device and improve communication. Processing reliability.

In an optional implementation, performing the target operation according to the first information and processing strategy may include:

When the first condition is met, disable the first cell;

Among them, the first condition includes:

Treatment strategies include disabling the first cell;

The resource scheduling situation indicates that the resource scheduling of the terminal device is abnormal;

The available neighbor cell condition indicates that the terminal device has available neighbor cells.

In this embodiment, the processing strategy for the first terminal in the first cell includes disabling the first cell, and the resource scheduling of the terminal device in the first cell is abnormal, and the terminal device can search for available neighboring cells in the first cell. , disable the first cell and register to the second cell; otherwise, you can continue to camp in the first cell. In this way, it can be ensured that the terminal device can only escape from the first cell when there is a real need to escape from the first cell, that is, the policy of disabling the first cell is applicable to the terminal device, and the terminal device has available neighboring cells. , which can prevent the terminal device from re-selecting a cell when cell re-selection is not required, thereby improving the communication fluency of the terminal device.

It should be noted that the embodiments of this application do not limit the execution order of the following determination operations: determine whether the processing strategy of the first cell includes disabling the first cell; determine whether the resource scheduling of the terminal device is abnormal; determine whether the terminal device exists Available neighborhoods.

In an optional implementation manner, the terminal device may determine whether the resource scheduling of the terminal device is abnormal after determining that the processing policy of the first cell includes disabling the first cell.

When the resource scheduling of the terminal device is abnormal, it is determined whether there is an available neighbor cell for the terminal device. When an available neighbor cell exists for the terminal device, the terminal device can escape from the first cell and register to the available neighbor cell. When the terminal device does not have available neighbor cells, it means that the communication quality of the shared area network is not good. If the terminal device turns on the 5G function, the terminal device cannot solve the communication abnormality problem even if it is registered in other cells. The terminal device can turn off the 5G function. Register to the third community.

If the resource scheduling of the terminal device is normal, it means that the terminal device can communicate normally in the first cell, that is, the policy of disabling the first cell does not apply to the terminal device and can continue to camp in the first cell.

In the case of disabling the first cell, in one implementation, the terminal device may permanently disable the first cell.

In another implementation manner, after disabling the first cell, the method may also include:

When the disabling period of the first cell reaches the first period, the disabling of the first cell is released.

In an optional implementation manner, the terminal device may set a timer, and use the timer to determine whether the disabled time period of the first cell reaches the first time period. In this method, the first electronic device can start the timer while disabling the first cell, and set the duration of the timer to the first duration. When the timer times out, the first cell can be undisabled. .

In this implementation, the terminal device can undisable the first cell after disabling the first cell for a period of time. In this way, after the first period of time, the first cell can still be used as a candidate registration cell for the terminal device, thereby expanding the The registration scope of the terminal device.

In another optional implementation, performing the target operation according to the first information and processing strategy may include:

When the second condition is met, turn off the 5G capability of the terminal device;

Wherein, the second condition includes: the processing strategy includes turning off the 5G capability of the terminal device registered to the first cell, and at least one of the following:

The available neighbor cell condition indicates that there is no available neighbor cell for the terminal device;

The communication situation indicates a communication abnormality of the terminal device.

In this embodiment, the processing strategy of the first terminal in the first cell includes turning off the 5G capability of the terminal device registered to the first cell, and the communication of the terminal device in the first cell is abnormal, and/or the terminal device is in the first cell. When a cell cannot search for available neighboring cells, the 5G capability of the terminal device is turned off and registered in the third cell; otherwise, it can continue to stay in the first cell. In this way, it can be ensured that the terminal device can turn off the 5G capability only when there is a real need to turn off the 5G capability, that is, when the policy of turning off the 5G capability is applicable to the terminal device. This can avoid the terminal device not having to turn off the 5G capability. Turn off 5G capabilities when capable, thereby improving the reliability of communication processing of terminal equipment.

It should be noted that the embodiments of this application do not limit the execution order of the following determination operations: determine whether the processing strategy of the first cell includes turning off the 5G capability of the terminal device registered to the first cell; determine whether the communication of the terminal device Abnormal; determine whether there are available neighbor cells for the terminal device.

In an optional implementation, the terminal device may determine whether the communication of the terminal device is abnormal after determining that the processing policy of the first cell includes turning off the 5G capability of the terminal device registered to the first cell.

In the case of abnormal communication of the terminal device, it is determined whether there is an available neighbor cell for the terminal device. If there are no available neighboring cells for the terminal device, it means that the communication quality of the shared area network is not good. You can turn off the 5G capability, escape from the first cell, and register to a non-shared cell. When there is an available neighbor cell for the terminal device, the terminal device can temporarily escape from the first cell by disabling the first cell and register to other shared cells to solve the communication abnormality problem.

If the communication of the terminal device is normal, it means that the terminal device can communicate normally in the first cell and the terminal device can continue to camp in the first cell.

In the case of turning off the 5G capability, in one implementation, the terminal device can permanently turn off the 5G capability.

In another implementation, after turning off the 5G capability of the terminal device, the method may also include:

When the 5G function of the terminal device is turned off for the second time period, the 5G function of the terminal device is turned on, and the 5G capability of the terminal device is reported to the target cell.

In an optional implementation, the terminal device can set a timer, and use the timer to determine whether the shutdown time of the 5G function reaches the second time. In this method, the first electronic device can start the timer while the 5G function is turned off, and set the timer duration to the second duration. When the timer times out, the 5G capability can be re-enabled, and Report 5G capabilities to the target cell.

In this implementation, the terminal device can re-enable the 5G capability after turning off the 5G capability for a period of time, and report the 5G capability to the target cell. In this way, the target cell can configure its measurement sharing cell based on the 5G capability of the terminal device and register with Sharing cells for 5G communication can improve communication quality.

It should be noted that the above-mentioned timer for determining whether the disabling duration of the first cell reaches the first duration and the timer for determining whether the deactivation duration of the 5G function reaches the second duration may be the same timer, or they may be different The timer can be specifically determined according to actual needs, and is not limited in the embodiments of this application.

In some embodiments, obtaining the processing policy corresponding to the first cell may include:

Receive second information, where the second information includes identification information of the abnormal cell and a processing strategy corresponding to the abnormal cell;

When the second information includes the identification information of the first cell, the processing policy corresponding to the first cell is obtained from the second information.

During specific implementation, the second information may be sent by the server. In one implementation, the server may periodically send the second information; in another implementation, the server may send the second information based on the request of the terminal device; in yet another implementation, the server may obtain the second information after the terminal device has not When connected to 5G SCG, the second information is sent.

In this embodiment of the present application, the server can be used to collect statistics on abnormal events of its registered cells sent by the terminal device, and determine whether the cell is an abnormal cell based on the number of abnormal events in each cell within a certain period of time, and further determine the abnormal cell. Corresponding processing strategy.

In an optional implementation, when the number of abnormal events in the first cell is greater than the first threshold, the processing strategy may include: disabling the first cell; In this case, the processing strategy may include: turning off the 5G capability of the terminal device registered to the first cell; wherein the second threshold is greater than the first threshold.

When the number of abnormal events in the first cell is greater than the first threshold, it means that the first cell is abnormal, and the first cell can be determined as an abnormal cell. In order to improve the communication fluency of the terminal equipment registered in the first cell, you can Add a processing strategy for the first cell: disable the cell. In this way, the terminal device can disable the first cell based on the processing policy to escape from the first cell.

When the number of abnormal events in the first cell is greater than the second threshold, it indicates that the communication quality in the shared network area is poor. In order to improve the communication fluency of the terminal equipment registered in the first cell, a processing policy can be added to the first cell: Turn off the 5G capability of the terminal device registered to the first cell. In this way, the terminal device can turn off 5G capabilities based on this processing strategy to escape from the shared network area.

The abnormal events of the cell sent by the terminal device may include at least one of the following: abnormal resource scheduling of the terminal device in the cell, and abnormal communication of the terminal device in the cell.

Reference value.

It should be noted that the various optional embodiments, implementations or implementations provided by the embodiments of this application can be implemented in combination or independently as long as they do not conflict with each other. The details can be determined according to actual needs. The embodiment does not limit this.

In order to facilitate understanding of the cell selection method provided by the above embodiment, the above cell selection method will be described below using a specific scenario embodiment. Figure 2 is a schematic flowchart of a scenario embodiment of the cell selection method provided by the embodiment of this application.

This scenario embodiment may specifically include the following steps:

Step 201: The mobile station turns on 5G and reports 5G capabilities to the network.

In this case, the network will query the 5G capabilities and configure the terminal to more easily register with the shared anchor cell.

Step 202: Determine whether the mobile station is registered in the shared anchor cell and is not connected to the 5G SCG.

If yes, step 203 is executed; otherwise, the process can be ended.

During specific implementation, the mobile station can determine whether to register for the shared anchor cell based on the PLMN and the registered frequency. For example, if the PLMN identifier of the first operator is registered with the frequency cell belonging to the second operator, it is determined to be registered. In the shared anchor cell.

Step 203: The mobile station determines whether the shared anchor cell is in the exception list determined by the background big data system.

If yes, go to step 204, otherwise end.

The background big data system (i.e., the aforementioned server) collects statistics on abnormal situations of each shared anchor cell.

If the number of anomalies in this shared anchor cell exceeds the threshold value Th1 (i.e., the first threshold mentioned above), the background big data joining policy "disable this cell";

If the number of anomalies in this shared anchor cell exceeds the threshold value Th2 (i.e., the aforementioned second threshold), the background big data join policy is "turn off 5G".

Step 204: The mobile station determines whether the policy corresponding to the shared anchor cell includes "disable this cell".

If yes, go to step 205, otherwise go to step 208.

Step 205: The mobile station determines whether resource scheduling is abnormal.

That is, to determine whether there are uplink and downlink scheduling problems in data transmission, the judgment method is:

If the mobile station's uplink and downlink data in this cell are lower than the thresholds Th_Rx and Th_Tx; and the delay of the TCP packet is greater than Th_tcp_delay, it can be determined that resource scheduling is abnormal.

Step 206: The mobile station determines whether there is an available neighbor cell.

That is, the mobile station determines whether it can find available neighboring cells nearby. If so, it goes to step 207; otherwise, it goes to step 208.

Step 207: The mobile station disables this shared anchor cell for N1 minutes.

Threshold N1 is the disabling threshold value set in this solution and can be adjusted according to the actual situation. For example, it can be set to 5 minutes.

Step 208: The mobile station determines whether continuous lagging or network disconnection occurs.

That is, the mobile terminal determines whether there are obvious abnormalities in the data transmission, such as network disconnection, multiple freezes and interruptions. If so, it goes to step 209, otherwise no operation is performed.

Step 209: The mobile station determines whether the policy corresponding to the shared anchor cell includes "turn off 5G".

If so, go to step 210, otherwise end.

Step 210: The mobile station turns off the 5G capability for N2 minutes.

Furthermore, the mobile station can report to the network that it does not support 5G capabilities, allowing the network to redirect or switch the terminal to a non-anchor cell.
