Communication method and communication device

Technical Field

The present application relates to the field of communication technology, and in particular to a communication method and a communication device.

Background technique

At present, when terminal devices are processing calls and other services, they may switch radio access technology (RAT). For example, when a terminal device is using a new radio (NR) network for a voice call, due to the instability of the NR network, it switches to a long term evolution (LTE) network for the voice call, and when the NR network is stable, it switches to the NR network for the voice call.

When a terminal device switches between different RATs, service interruption may occur, affecting the user experience.

Summary of the invention

The present application provides a communication method and a communication device. When a terminal device detects a change in a PDCP parameter and has not yet been fully configured, the terminal device can feedback the event to a first network device so that the first network device can perceive the event and process the event, thereby reducing the probability of causing PDCP layer abnormalities, thereby reducing the impact on the services performed by the terminal device and improving user experience.

In a first aspect, a communication method is provided, the method comprising: determining a first event, the first event comprising a Packet Data Convergence Protocol (PDCP) parameter change, and no information indicating a complete configuration is received; sending first information to a first network device, the first information being used to feedback the first event.

In this way, the terminal device can feedback the PDCP parameter change and the event of not receiving the information indicating the complete configuration to the first network device, so that the first network device can perceive the event and process the event, thereby reducing the probability of causing PDCP layer abnormalities, thereby reducing the impact on the services performed by the terminal device, and thereby improving the user experience.

In combination with the first aspect, in some implementations of the first aspect, the first information is carried in a media access control control element (MAC CE) message.

In this way, the terminal device feeds back the first event to the first network device via the MAC CE message, which is conducive to feedback of the first event.

In combination with the first aspect, in certain implementations of the first aspect, the first information is set in a reserved field of the MAC CE message.

In this way, the first information can be transmitted without affecting the transmission of other information.

In combination with the first aspect, in some implementations of the first aspect, sending the first information includes: sending a user equipment information response (UE information response, UIR) message in response to a request of the first network device, where the UIR message includes the first information.

In this way, after the terminal device determines the first event, it can report the first event as abnormal information to the first network device.

In combination with the first aspect, in some implementations of the first aspect, the first information further includes at least one of the following: the time when the first event occurs, the cell where the first event occurs, or the geographical location where the first event occurs.

In this way, statistics based on the time when the first event occurred, the cell where the first event occurred, or the geographical location where the first event occurred are performed, which is beneficial for the first network device to obtain at least one cell or at least one geographical location.

In combination with the first aspect, in certain implementations of the first aspect, before determining the first event, the method also includes: sending a first request message to the second network device, the first request message being used to request execution of the target service; receiving second information from the second network device in response to the first request message; reporting a second event to the second network device, the second event being used to indicate that the first network is superior to the second network; receiving a response message from the second network device in response to the second event, the response message being used to indicate access to the first network; sending a second request message to the first network device in response to the response message, the second request message being used to request access to the first network; receiving third information from the first network device in response to the second request message; determining the first event, including: the PDCP parameters included in the third information are different from the PDCP parameters included in the second information, and the third information does not contain information for indicating a complete configuration, and determining the first event.

In this way, when the terminal device is executing the target service, during the process of switching from the second network to the first network, the PDCP parameters received by the terminal device change, and no information indicating a complete configuration is received. This event can be fed back to the first network device so that the first network device can perceive the event and process the event, thereby reducing the probability of causing PDCP layer abnormalities, thereby reducing the impact on the services performed by the terminal device, and thereby improving the user experience.

In a second aspect, a communication method is provided, which is applied to a first network device, and the method includes: receiving first information, the first information is used to feedback a first event, the first event includes a change in a packet data convergence protocol PDCP parameter, and no information indicating a complete configuration is received; in response to the first information, sending information indicating a complete configuration.

In combination with the second aspect, in some implementations of the second aspect, the first information is carried in a media access control control element MAC CE message.

In combination with the second aspect, in certain implementations of the second aspect, the first information is set in a reserved field of the MAC CE message.

In combination with the second aspect, in certain implementations of the second aspect, before receiving the first information, the method also includes: receiving a second request message, the second request message being used to request access to the first network; sending third information in response to the second request message; wherein the third information does not contain information for indicating a complete configuration.

In this way, the first network device responds to the first event and can send information indicating complete configuration to the terminal device when the terminal device requests to access the first network. This is conducive to timely complete configuration, reducing the probability of target service interruption and improving user experience.

According to a third aspect, a communication method is provided, which is applied to a first network device, and the method includes: obtaining multiple first information from multiple terminal devices, any one of the multiple first information is used to feedback a first event, the first event includes a change in a packet data convergence protocol PDCP parameter, and no information indicating a complete configuration is received, and any one of the multiple terminal devices is a device that sends any one of the first information; in response to the multiple first information, obtaining at least one cell or at least one geographic location.

In this way, the first network device counts the occurrence of the first event to obtain at least one cell or at least one geographical location, so as to reduce the probability of the first event occurring in these areas or geographical locations.

In combination with the third aspect, in certain implementations of the third aspect, obtaining multiple first information from multiple terminal devices includes: sending requests to multiple terminal devices; receiving multiple user equipment information response UIR messages from the multiple terminal devices in response to the requests, the UIR messages all including the first information.

In combination with the third aspect, in certain implementations of the third aspect, in response to multiple first information, at least one cell or at least one geographic location is obtained, including: based on multiple first information, counting the number of occurrences of a first event in the same cell or the same geographic location within a first time period; obtaining at least one cell or at least one geographic location through the relationship between the number of occurrences and a preset number, wherein the number of occurrences of the first event in any one of the at least one cell is greater than the preset number, and the number of occurrences of the first event in any one of the at least one geographic location is greater than the preset number.

This helps the first network device to obtain at least one cell or at least one geographical location.

In combination with the third aspect, in certain implementations of the third aspect, the method also includes: receiving a third request message from the target terminal device, the third request message is used to request access to the first network; at least one cell includes the cell where the target terminal device is located, or at least one geographical location includes the geographical location where the target terminal device is located; in response to the third request message, sending fourth information, the fourth information including information for indicating a complete configuration.

In this way, when a target terminal device located in any of at least one cell, or a target terminal device located in any of at least one geographical location, requests access to the first network, the first network device sends information indicating a complete configuration, which is conducive to reducing the frequency of the first event occurring in at least one cell or at least one geographical location, thereby reducing the impact on the services performed by the target terminal device and improving the user experience.

The information to be indicated may also be indirectly indicated by indicating other information, wherein the other information and the information to be indicated have an association relationship. It is also possible to indicate only a part of the information to be indicated, while the other parts of the information to be indicated are known or agreed in advance.

To facilitate understanding of the embodiments of the present application, a communication system applicable to the embodiments of the present application is first described in detail with reference to FIG. 1 .

Fig. 1 shows a schematic diagram of a communication system provided by an embodiment of the present application. As shown in Fig. 1 , the communication system includes a terminal device 110 , a network device 120 and a network device 130 .

The terminal device 110 may send uplink data or control information to the network device 120, and the network device 120 may send downlink data or control information to the terminal device 110. The terminal device 110 may also send uplink data or control information to the network device 130, and the network device 130 may send downlink data or control information to the terminal device 110.

In some scenarios, the terminal device 110 can implement services such as calls through the network device 120 or the network device 130. In the scenarios of evolved packet system (EPS) fallback, voice over new radio (VoNR) or packet switched (PS), the terminal device 110 may switch RAT when processing services such as calls. For example, in the VoNR scenario, the terminal device 110 can access the NR network through the network device 120 to implement voice call services. Alternatively, the terminal device 110 can access the LTE network through the network device 130 to implement voice call services. When the terminal device 110 communicates with the network device 120 and uses the NR network for voice calls, it can switch to the LTE network due to the instability of the NR network. When the terminal device 110 communicates with the network device 130 and uses the LTE network for voice calls, it can switch to the NR network when the NR network is stable.

When the terminal device 110 switches from the NR network to the LTE network, it needs to send a message requesting access to the LTE network to the network device 130. In response to the message requesting access to the LTE network, the network device 130 instructs the terminal device 110 to access the LTE network. When the terminal device 110 switches from the LTE network to the NR network, it needs to send a message requesting access to the NR network to the network device 120. In response to the message requesting access to the NR network, the network device 120 instructs the terminal device 110 to access the NR network.

Currently, when the terminal device 110 switches from an LTE network to an NR network, or from an NR network to an LTE network, anomalies may occur, resulting in service interruption and affecting user experience.

When the network device 130 instructs the terminal device 110 to access the LTE network, packet data convergence protocol (PDCP) parameters may be configured for the terminal device 110. When the network device 120 instructs the terminal device 110 to access the NR network, PDCP parameters may also be configured for the terminal device 110. In some scenarios, the network device 130 and the network device 120 may configure different PDCP parameters for the terminal device 110.

In some examples, when the network device 130 and the network device 120 are produced by different manufacturers, the network device 130 and the network device 120 may configure different PDCP parameters for the terminal device 110 .

In other examples, the network device 130 and the network device 120 are devices produced by the same manufacturer, but are different versions. The network device 130 and the network device 120 can configure different PDCP parameters for the terminal device 110 .

The terminal device 110 receives different PDCP parameters and needs to perform full configuration. However, the network device 120 or the network device 130 cannot perceive the PDCP parameters configured by other devices for the terminal device 110, and may not indicate full configuration in the radio link control protocol (RLC) when configuring the PDCP parameters. In this way, the terminal device 110 cannot use the changed PDCP parameters and will continue to use the previous PDCP parameters, resulting in PDCP anomalies and affecting voice call services.

It can be seen that the PDCP anomaly occurs during the RAT switching process of the terminal device 110 because the terminal device 110 switches from the NR network to the LTE network, the PDCP parameters from the network device 120 are different from the PDCP parameters from the network device 130, and the information indicating the complete configuration from the network device 130 is not received. Alternatively, the terminal device 110 switches from the LTE network to the NR network, the PDCP parameters from the network device 120 are different from the PDCP parameters from the network device 130, and the information indicating the complete configuration from the network device 120 is not received. In other words, there is a compatibility problem between different networks.

In view of this, an embodiment of the present application provides a communication method and a communication device. When the PDCP parameters of the terminal device change during the process of switching RAT, and no information indicating a complete configuration is received, the terminal device can feedback the event to the network device so that the network device can perceive the event and process the event, thereby reducing the probability of causing PDCP layer abnormalities, thereby reducing the impact on the services performed by the terminal device and improving the user experience.

The communication method provided by the present application will be described in detail below with reference to the accompanying drawings.

It can be understood that the interaction process diagram of the present application uses the terminal device and the network device as the execution subject of the interaction diagram as an example to illustrate the method provided by the present application, but the present application does not limit the execution subject of the interaction diagram.

For example, a network device may also be a chip, a chip system, or a processor applied to a network device, or a logical node, a logical module, or software that can realize all or part of the functions of a network device. For another example, a terminal device may also be a chip, a chip system, or a processor applied to a terminal device, or a logical node, a logical module, or software that can realize all or part of the functions of a terminal device.

FIG2 shows a schematic flow chart of a communication method provided in an embodiment of the present application. The method can be applied to the communication system shown in FIG1 above, but the embodiment of the present application does not limit this. As shown in FIG2, the method may include the following steps:

S201. The terminal device determines a first event, where the first event includes a PDCP parameter change and no information indicating a complete configuration is received.

The PDCP parameters may include one or more of the uplink PDCP sequence number length, the downlink PDCP sequence number length, the discard timer, the header compression configuration, the reordering timer, and the uplink split threshold. When the terminal device detects that the PDCP parameters received before and after are different, it can be determined that the PDCP parameters have changed.

Exemplarily, if the duration of the discard timer in the PDCP parameters received by the terminal device from the first network device is 10 milliseconds, and the duration of the discard timer in the PDCP parameters received by the terminal device again from the first network device is 20 milliseconds, it can be determined that the PDCP parameters have changed.

S202. The terminal device sends first information to the first network device, where the first information is used to feedback a first event.

When the terminal device detects that the PDCP parameters have changed and does not receive information indicating a complete configuration, it can feedback this situation to the first network device so that the first network device can perform a complete configuration so that the terminal device can use the changed PDCP parameters.

In some examples, the terminal device may be the terminal device 110 in the communication system shown in FIG. 1 above. The first network device may be the network device 120. During the process of the terminal device 110 switching from the LTE network to the NR network, the PDCP parameters received by the terminal device from the network device 120 are different from the PDCP parameters received from the network device 130, and the information indicating the complete configuration from the network device 120 is not received, and the event may be fed back to the network device 120. Alternatively, the first network device may be the network device 130. During the process of the terminal device 110 switching from the NR network to the LTE network, the PDCP parameters received by the terminal device from the network device 120 are different from the PDCP parameters received from the network device 130, and the information indicating the complete configuration from the network device 130 is not received, and the event may be fed back to the network device 130.

The first network device receives the first information from the terminal device, and in response to the first information, can send information for complete configuration to the terminal device, or can count the number of times the terminal device feeds back the first event through the first information, so as to facilitate statistics on the anomalies generated by the terminal device and facilitate subsequent processing.

According to the communication method provided in the embodiment of the present application, the terminal device can feedback to the first network device the event of PDCP parameter changes and the event of not receiving information indicating a complete configuration, so that the first network device can perceive the event and process the event, thereby reducing the probability of causing PDCP layer abnormalities, thereby reducing the impact on the services performed by the terminal device and improving the user experience.

In an embodiment of the present application, the terminal device can send the above-mentioned first information in a variety of ways.

In a possible implementation, the first information may be carried in a media access control element MAC CE message. The terminal device may actively send the first information to the first network device through the MAC CE message.

In this way, the terminal device feeds back the first event to the first network device via the MAC CE message, which is conducive to feedback of the first event.

The MAC CE message may include multiple fields, wherein the 100001-101111 field and the 100001-110110 field are both reserved fields. In some examples, the first information may be set in the reserved field in the MAC CE.

In this way, the first information can be transmitted without affecting the transmission of other information.

If the terminal device feeds back the first event to the first network device via a MAC CE message, the first network device may send information indicating a complete configuration to the terminal device in response to the MAC CE message.

For example, Fig. 3 shows a schematic flow chart of a communication method provided in an embodiment of the present application. As shown in Fig. 3, the method 300 may include the following steps:

S301. The terminal device determines a first event, where the first event includes a PDCP parameter change and no information indicating a complete configuration is received.

S302: The terminal device sends first information to the first network device, and correspondingly, the first network device receives the first information, wherein the first information is used to feedback the first event.

The first information may be carried in a MAC CE message. After the terminal device determines the first event, it may feed back the first event to the first network device via a MAC CE message.

S303. The first network device sends information indicating a complete configuration to the terminal device in response to the first information. Correspondingly, the terminal device receives the information indicating a complete configuration.

In some implementations, the information for indicating the complete configuration may be carried in an RRC reconfiguration message. In the RRC reconfiguration message, the information for indicating the complete configuration may be represented as a field fullConfig=true in the RRC reconfiguration message.

According to the communication method provided in the embodiment of the present application, after the terminal device determines the first event, it can feedback the event to the first network device. Based on the event, the first network device can send information indicating a complete configuration to the terminal device, which is conducive to timely and complete configuration of the terminal device.

The method may be applicable to the different RAT switching scenarios shown in Fig. 1. During the switching process between different RATs, the terminal device may determine a first event.

For example, Fig. 4 shows a schematic flow chart of a communication method provided in an embodiment of the present application. As shown in Fig. 4, the method 400 may include the following steps:

S401: The terminal device may send a first request message to the second network device, and correspondingly, the second network device receives the first request message, wherein the first request message is used to request execution of a target service.

The target service may refer to services that require a cellular communication network, such as calls, videos, and games. When the terminal device is performing services that require a cellular communication network, such as calls, videos, and games, the terminal device may send a first request message to the second network device.

S402: In response to the first request message, the second network device may send second information to the terminal device, and correspondingly, the terminal device receives the second information, wherein the second information may include the first PDCP parameter.

The first PDCP parameter may include one or more of an uplink PDCP sequence number length, a downlink PDCP sequence number length, a discard timer, a header compression configuration, a reordering timer, and an uplink diversion threshold.

In some implementations, the second information may be carried in a radio resource control (RRC) configuration message. The terminal device may establish an RRC connection with the second network device through the information included in the RRC configuration message. The steps performed during the process of establishing the RRC connection between the terminal device and the second network device are not described in detail here.

S403: The terminal device sends a second event to the second network device, and correspondingly, the second network device receives the second event, wherein the second event is used to indicate that the first network is superior to the second network.

When the terminal device communicates with the second network device, the second network is used to implement the target service. The terminal device can detect the signal quality of the second network and the signal quality of other surrounding network signals, and when it is determined that the first network is better than the second network, a second event can be sent to the second network device.

S404: The second network device sends a response message to the terminal device in response to the second event, and the terminal device receives the response message accordingly. The response message is used to indicate access to the first network.

The second network device receives the second event and may allow the terminal device to access the first network to better implement the target service.

S405: In response to the response message, the terminal device may send a second request message to the first network device, and correspondingly, the first network device receives the second request message, wherein the second request message is used to request access to the first network.

The first network device is different from the second network device. In the communication system shown in FIG. 1 , the first network device may be the network device 120 , and the second network device may be the network device 130 , or the first network device may be the network device 130 , and the second network device may be the network device 120 .

It can be understood that when the first network device is network device 120, the first network is an NR network, and when the second network device is network device 130, the second network is an LTE network. When the first network device is network device 130, the first network is an LTE network, and when the second network device is network device 120, the second network is an NR network.

In the EPS fallback, VoNR or PS switching scenario, the terminal device may have a network switching requirement and can send a second request message to the first network device.

Exemplarily, in a VoNR scenario, when a terminal device uses the NR network for a voice call, since the LTE network is superior to the NR network, the terminal device can send a second request message to the first network device, where the second request message is used to request access to the LTE network.

S406. In response to the second request message, the first network device may send third information to the terminal device, and correspondingly, the terminal device receives the third information. The third information may include the second PDCP parameter, and the third information may not include information for indicating a complete configuration. The second PDCP parameter includes information different from the information in the first PDCP parameter.

In some implementations, the third information does not include information for indicating a complete configuration, which can be represented by the fact that there is no fullConfig field in the third information.

In some implementations, the third information may be carried in an RRC reconfiguration message. The first network device may send the second PDCP parameter to the terminal device via the RRC reconfiguration message.

S407: The terminal device determines the first event in response to the third information.

The PDCP parameters in the second information are different from the PDCP parameters in the third information, and there is no information in the third information for indicating a complete configuration, and the terminal device can determine the first event.

It is understandable that after the terminal device determines the first event, it can perform the method shown in Figure 3 with the first network device. In this way, the terminal device can perform complete configuration through the information sent by the first network device to indicate complete configuration, and continue to implement the target service through the first network device, which can reduce the probability of interruption of the target service and improve user experience.

In another possible implementation, the above S202, the terminal device sending the first information to the first network device, may include: in response to a request from the first network device, sending a user equipment information response UIR message, where the UIR message includes the first information. In response to the request from the first network device, the terminal device passively sends the first information to the first network device.

In this example, the request of the first network device may be a user equipment information request (UE information request). The UIR message includes an rlf-Report-r16 field, which may include multiple abnormal reason values, such as t310-Rxpiry, where t310-Rxpiry is used to indicate that t310 timeout results in link failure.

In an embodiment of the present application, a new information element is added to the rlf-Report-r16 field in the UIR message, and the new information element can be used to indicate the first information.

In this way, after the terminal device determines the first event, it can report the first event as abnormal information to the first network device.

The first network device may acquire first information of a plurality of terminal devices, and obtain at least one cell or at least one geographical location based on the first information.

In this way, the first network device counts the occurrence of the first event and obtains at least one cell or at least one geographical location, so as to reduce the probability of the first event occurring in these areas or geographical locations. A processing strategy is formed by big data learning.

When a target terminal device located in any one of at least one cell, or a target terminal device located in any one of at least one geographical location, requests the first network device to access the first network, the first network device accessing the first network can send information indicating a complete configuration to the target terminal device so that the target terminal device successfully accesses the first network.

For example, Fig. 5 shows a schematic flow chart of a communication method provided in an embodiment of the present application. As shown in Fig. 5, the method 500 may include the following steps:

S501. Multiple terminal devices determine a first event.

Each of the multiple terminal devices may determine the first event. The time at which each terminal device determines the first event may be the same or different, and this is not limited in the embodiments of the present application. The geographical location of each terminal device may be different. The multiple terminal devices may include terminal devices in the same cell or in different cells.

Each of the multiple terminal devices may determine the first event in the scenario shown in FIG. 4 above.

S502: The first network device may send a request to multiple terminal devices.

It is understandable that the request may be the above user equipment information request. The request is used to instruct the terminal device to report an abnormality.

The first network device may send a request to each of the multiple terminal devices. The timing at which the first network device sends a request to each terminal device may be the same or different, and this embodiment of the application does not limit this.

S502 may be after S501 or before S501, which is not limited in the present embodiment. The request in S502 may be periodically sent by the first network device to the terminal device to facilitate statistics of abnormalities occurring in the terminal device.

S503: In response to the request, the plurality of terminal devices send first information to the first network device, where the first information is used to feedback the first event. The first network device receives the plurality of first information.

After determining the first event, each of the plurality of terminal devices may respond to the request and feed back the first event to the terminal device through the first information. The first information may be carried in a UIR message.

S504: In response to the multiple pieces of first information, the first network device obtains at least one cell or at least one geographical location.

The first network device may obtain a plurality of first information, and may perform statistics on the first events to obtain at least one cell or at least one geographical location where the frequency of the first event is high.

Optionally, the first information may include at least one of the following: the time when the first event occurs, the cell where the first event occurs, or the geographical location where the first event occurs.

The first network device can count the number of occurrences of the first event in the same cell or the same geographical location within a first time period based on multiple first information; and obtain at least one cell or at least one geographical location through the relationship between the number of occurrences and a preset number of times, wherein the number of occurrences of the first event in any one of the at least one cell is greater than the preset number of times, and the number of occurrences of the first event in any one of the at least one geographical location is greater than the preset number of times.

This helps the first network device to obtain at least one cell or at least one geographical location.

S505. The target terminal device sends a third request message to the first network device, and the first network device receives the third request message accordingly. The third request message is used to request access to the first network. The at least one cell includes the cell where the target terminal device is located, or the at least one geographical location includes the geographical location where the target terminal device is located.

S506: At least one cell includes the cell where the target terminal device is located, or at least one geographical location includes the geographical location where the target terminal device is located, and the first network device determines fourth information in response to the third request message, wherein the fourth information includes information for indicating a complete configuration.

S507: The first network device may send fourth information to the target terminal device, and correspondingly, the target terminal device receives the fourth information, wherein the fourth information includes information for indicating a complete configuration.

The cell where the target terminal device is located is in at least one cell obtained based on big data learning, or the geographical location where the target terminal device is located is in at least one geographical location obtained based on big data learning. The first network device can send information indicating a complete configuration so that the terminal device can complete the configuration based on the complete configuration information to access the first network.

It can be understood that the fourth information may also include PDCP parameters.

In this way, when a target terminal device located in any of at least one cell, or a target terminal device located in any of at least one geographical location, requests access to the first network, the first network device sends information indicating a complete configuration, which is conducive to reducing the frequency of the first event occurring in at least one cell or at least one geographical location, thereby reducing the impact on the services performed by the target terminal device and improving the user experience.

In addition to the methods shown in FIG. 3 and FIG. 5 above, an embodiment of the present application also provides a communication method that is beneficial to reducing the probability of a first event occurring in a terminal device.

For example, Fig. 6 shows a schematic flow chart of a communication method provided in an embodiment of the present application. As shown in Fig. 6, the method 600 may include the following steps:

S601: The terminal device sends a second event to the second network device, and correspondingly, the second network device receives the second event, wherein the second event is used to indicate that the first network is superior to the second network.

During the communication between the terminal device and the second network device, if it is detected that the first network is superior to the second network, the second event can be reported to the second network device.

S602: In response to the second event, the second network device sends a response message to the terminal device, and correspondingly, the terminal device receives the response message, wherein the response message is used to indicate access to the first network.

This step may refer to the above-mentioned S404 and will not be described in detail here.

S603: In response to the response message, the second network device sends fifth information to the first network device, and correspondingly, the first network device receives the fifth information, wherein the fifth information includes the third PDCP parameter.

The third PDCP parameter is sent to the terminal device during the communication between the second network device and the terminal device.

S603 and S602 may be executed simultaneously by the second network device, or may be executed one after another, which is not limited in this embodiment of the present application.

S604: In response to the response message, the terminal device sends a third request message to the first network device, and correspondingly, the first network device receives the third request message, wherein the third request message is used to request access to the first network.

S605. In response to the third request message, the first network device may send sixth information to the terminal device, and correspondingly, the terminal device receives the sixth information, wherein the PDCP parameters included in the sixth information are the same as the PDCP parameters included in the fifth information, that is, the sixth information includes the third PDCP parameters.

The PDCP parameters configured by the first network device for the terminal device may be the same as the PDCP parameters configured by the second network device for the terminal device. In this way, when the terminal device switches from the second network to the first network, the received PDCP parameters are the same and the PDCP parameters do not change, which is beneficial to reduce the probability of the first event occurring.

In the method shown in FIG. 3 above, when the first event occurs, the terminal device actively feeds back the first event to the first network device, and the first network device can reduce the impact of the first event on the terminal device by sending information indicating a complete configuration to the terminal device. In the method shown in FIG. 5 above, when the first event occurs, the terminal device responds to the request of the first network device and passively feeds back the first event to the first network device, and the first network device regards the first event as an abnormal event and collects statistics on the abnormal events that have occurred, so as to reduce the occurrence of the first event by subsequently sending information indicating a complete configuration.

In some implementations, in the method shown in FIG. 3 above, when the first event occurs, the terminal device may also send one or more information of the cell where the first event occurs, the geographical location where the first event occurs, or the time when the first event occurs to the first network device, and the first network device may record this information so as to perform statistics on the first event based on the method shown in FIG. 5 to obtain at least one cell or at least one geographical location. In this way, when at least one cell includes the cell where the target terminal device is located, or at least one geographical location includes the geographical location where the target terminal device is located, the first network device sends information indicating a complete configuration to the target terminal device in response to the request of the target terminal device to access the first network.

In this way, when the first event occurs, the first network device can reduce the impact of the first event on the terminal device by sending information indicating a complete configuration to the terminal device, and can also reduce the probability of the first event occurring subsequently.

It should be understood that the order of execution of the above methods does not necessarily mean the order in which they are executed. The order in which each process is executed should be determined by its function and internal logic.
