To facilitate understanding of embodiments of the present application, a communication system suitable for use in embodiments of the present application will be described in detail with reference to fig. 1.

Fig. 1 shows a schematic diagram of a communication system according to 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 transmit uplink data or control information to the network device 120, and the network device 120 may transmit 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, terminal device 110 may implement services such as a call through network device 120 or network device 130. In the scenario of Evolved PACKET SYSTEM (EPS) fallback, new air interface supported voice (voice over new radio, voNR) or packet switched (PACKET SWITCHED, PS) handover, the terminal device 110 may switch rats when handling traffic such as calls. For example, in the VoNR scenario, terminal device 110 may implement a voice call service through network device 120 access to the NR network. Or the terminal device 110 may access the LTE network through the network device 130 to implement a voice call service. The terminal device 110 communicates with the network device 120, and can switch to the LTE network due to instability of the NR network during voice call using the NR network. The terminal device 110 communicates with the network device 130, and can switch to the NR network when the NR network is stable during a voice call using the LTE network.

The terminal device 110 switches from the NR network to the LTE network and needs to send a message requesting access to the LTE network to the network device 130. The network device 130 instructs the terminal device 110 to access the LTE network in response to the message requesting access to the LTE network. Terminal device 110 switches from the LTE network to the NR network and needs to send a message to network device 120 requesting access to the NR network. Network device 120 instructs terminal device 110 to access the NR network in response to the message requesting access to the NR network.

At present, in the process of switching the terminal device 110 from the LTE network to the NR network or from the NR network to the LTE network, an abnormality may occur, which leads to service interruption and affects user experience.

The network device 130 may configure packet data convergence protocol (PACKET DATA convergence protocol, PDCP) parameters for the terminal device 110 during the process of instructing the terminal device 110 to access the LTE network. The network device 120 may also configure PDCP parameters for the terminal device 110 during the process of instructing the terminal device 110 to access the NR network. In some scenarios, network device 130 and network device 120 may configure different PDCP parameters for terminal device 110.

In some examples, when network device 130 and network device 120 are devices manufactured by different vendors, network device 130 and network device 120 may configure different PDCP parameters for terminal device 110.

In other examples, network device 130 and network device 120 are devices manufactured by the same vendor, but for different versions, network device 130 and network device 120 may configure different PDCP parameters for terminal device 110.

The terminal device 110 receives the different PDCP parameters and needs to perform a full configuration (Full configuration). But the network device 120 or the network device 130 cannot perceive PDCP parameters configured by other devices for the terminal device 110, and may not indicate full configuration in the radio link control (radio link control protocol, RLC) protocol when the PDCP parameters are configured. In this way, the terminal device 110 cannot use the changed PDCP parameters, and the previous PDCP parameters are delayed, so that PDCP anomalies occur, and the voice call service is affected.

As can be seen, PDCP anomalies occur during the handover of the terminal device 110 from the NR network to the LTE network, because the PDCP parameters from the network device 120 are different from the PDCP parameters from the network device 130, and no information indicating the complete configuration is received from the network device 130. Or terminal device 110 switches from the LTE network to the NR network, PDCP parameters from network device 120 are different from PDCP parameters from network device 130, and no information indicating a complete configuration is received from network device 120. In other words, compatibility of the coordination between different networks is problematic.

In view of this, the embodiments of the present application provide a communication method and a communication apparatus, where in a process of switching RATs, a terminal device changes PDCP parameters, and in the case that information for indicating complete configuration is not received, the terminal device may feed back the event to a network device, so that the network device senses the event and processes the event, thereby reducing the probability of causing an abnormality of a PDCP layer, further reducing the influence on services performed by the terminal device, and improving user experience.

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

It can be understood that in the interactive flow diagram of the present application, the terminal device and the network device are taken as the execution bodies of the interactive diagrams to illustrate the method provided by the present application, but the present application is not limited to the execution bodies of the interactive diagrams.

For example, the network device may be a chip, a chip system, or a processor applied to the network device, or may be a logic node, a logic module, or software capable of implementing all or part of the functions of the network device. For another example, the terminal device may be a chip, a chip system, or a processor applied to the terminal device, or may be a logic node, a logic module, or software capable of implementing all or part of the functions of the terminal device.

Fig. 2 shows a schematic flow chart of a communication method provided by an embodiment of the application. The method may be applied to the communication system shown in fig. 1 and is not limited thereto according to the embodiment of the present application. As shown in fig. 2, the method may include the steps of:

s201, the terminal equipment determines a first event, wherein the first event comprises PDCP parameter change, and information for indicating complete configuration is not received.

The PDCP parameters 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, an uplink shunt threshold value. When the terminal device detects that the PDCP parameters received before and after are different, it can determine that the PDCP parameters are changed.

Illustratively, if the duration of the discard timer in the PDCP parameters received by the terminal device from the first network device is 10 ms and the duration of the discard timer in the PDCP parameters received again by the terminal device from the first network device is 20 ms, then the PDCP parameter change may be determined.

S202, the terminal equipment sends first information to the first network equipment, wherein the first information is used for feeding back a first event.

The terminal device detects that the PDCP parameters are changed, and does not receive information indicating complete configuration, and may feed back this condition to the first network device, so that the first network device performs complete configuration, so that the terminal device may use the changed PDCP parameters.

In some examples, the terminal device may be terminal device 110 in the communication system shown in fig. 1 described above. The first network device may be network device 120. In the process of switching the terminal device 110 from the LTE network to the NR network, the terminal device receives PDCP parameters from the network device 120 differently from PDCP parameters received from the network device 130, and does not receive information indicating the complete configuration of the network device 120, and may feed back this event to the network device 120. Or the first network device may be the network device 130. In the process of switching the terminal device 110 from the NR network to the LTE network, the terminal device receives PDCP parameters from the network device 120 differently from PDCP parameters received from the network device 130, and does not receive information indicating the complete configuration of the network device 130, and may feed back this event to the network device 130.

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

According to the communication method provided by the embodiment of the application, the terminal equipment can feed back the PDCP parameter change to the first network equipment, and the event for indicating the complete configuration information is not received, so that the first network equipment can conveniently sense the event and process the event, thereby reducing the probability of causing the abnormality of the PDCP layer, further reducing the influence on the service carried out by the terminal equipment and improving the user experience.

In the embodiment of the present application, the terminal device may send the first information in multiple manners.

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

The MAC CE message may include a plurality of fields, where 100001-101111 fields and 100001-110110 fields are reserved fields, and in some examples, the first information may be set in a reserved field in the MAC CE.

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

Illustratively, fig. 3 shows a schematic flow chart of a communication method provided by an embodiment of the present application. As shown in fig. 3, the method 300 may include the steps of:

S301, the terminal equipment determines a first event, wherein the first event comprises PDCP parameter change, and information for indicating complete configuration is not received.

S302, the terminal equipment sends first information to the first network equipment, and correspondingly, the first network equipment receives the first information. Wherein the first information is used to feed back the first event.

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

S303, the first network equipment responds to the first information and sends information for indicating the complete configuration to the terminal equipment, and correspondingly, the terminal equipment receives the information for indicating the complete configuration.

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

According to the communication method provided by the embodiment of the application, after the terminal equipment determines the first event, the event can be fed back to the first network equipment, and the first network equipment can send the information for indicating the complete configuration to the terminal equipment based on the event, so that the terminal equipment can perform the complete configuration in time.

The method may be applied to the different RAT handover scenarios shown in fig. 1 and described above. The terminal device may determine the first event during a handover of a different RAT.

Illustratively, fig. 4 shows a schematic flow chart of a communication method provided by an embodiment of the present application. As shown in fig. 4, the method 400 may include the steps of:

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. The first request message is used for requesting to execute the target service.

The target service may refer to a call, video, game, etc. that requires a cellular communication network. The terminal device may send a first request message to the second network device when a call, a video, a game, or the like is performed requiring a service of the cellular communication network.

S402, the second network device may send second information to the terminal device in response to the first request message, 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, an uplink shunt threshold value.

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

S403, the terminal equipment sends a second event to the second network equipment, and correspondingly, the second network equipment receives the second event. Wherein the second event is used to indicate that the first network is preferred over the second network.

And when the terminal equipment communicates with the second network equipment, the second network is used for realizing the target service. The terminal device may detect the signal quality of the second network and the signal quality of other surrounding network signals, and may send a second event to the second network device when it is determined that the first network is better than the second network.
