Description

Parameter reconfiguration method and device

Technical Field

The present application relates to the field of communications, and in particular, to a method and an apparatus for parameter reconfiguration.

Background

With the rapid development of wireless communication and the rapid increase of market demand, people-to-people communication has been unable to meet the demand, and therefore, internet of things (IoT) technology has come into force. For example, machine-to-machine communication (M2M) is the communication of information and data to each other through wireless networks, which is an important direction for the development of IoT. Most of the M2M devices are small battery-powered systems, such as intelligent meter reading systems, and need to periodically detect and report usage conditions of water, electricity, gas, and the like. The traffic transmitted between M2M devices may be Machine Type Communication (MTC) traffic, which has some special traffic characteristics, such as small transmission data amount, obvious traffic periodicity, low power consumption, large terminal data amount, and the like.

In a word, the IoT technology requires a high disconnection rate between devices, and the reliability of signal transmission between devices needs to be solved urgently.

Disclosure of Invention

The application provides a method and a device for parameter reconfiguration, which can improve the reliability of signal transmission.

In a first aspect, a method for parameter reallocation is provided, the method including: the terminal receives a Radio Resource Control (RRC) connection reconfiguration message by adopting the first parameter, wherein the RRC connection reconfiguration message is used for indicating a second parameter; the terminal sends an RRC connection reconfiguration complete message by adopting the first parameter, wherein the RRC connection reconfiguration complete message is used for indicating the terminal to receive the RRC connection reconfiguration message by adopting the first parameter; and the terminal adopts the second parameter to communicate with the network equipment after sending the RRC connection reconfiguration finishing message.

The terminal receives an RRC connection reconfiguration message used for indicating a second parameter by adopting the first parameter, reconfigures the second parameter, sends an RRC connection reconfiguration complete message to the network equipment by adopting the first parameter after the reconfiguration of the second parameter is completed, and communicates with the network equipment by adopting the second parameter after the RRC connection reconfiguration complete message is sent, so that the problem that the use parameters of a transceiving end are inconsistent due to the fact that the terminal still communicates with the network equipment by using the first parameter when the terminal does not successfully receive the RRC connection reconfiguration message and the network equipment communicates with the terminal by adopting the second parameter after the RRC connection reconfiguration complete message is sent by the network equipment is solved. That is to say, after the terminal sends the RRC connection complete message via the first parameter, the terminal communicates with the network device via the second parameter, so that a call drop rate of communication between the terminal and the network device is reduced.

In some possible implementations, the method further includes the terminal starting a timer when sending the RRC connection reconfiguration complete message; after sending the RRC connection reconfiguration complete message, the terminal communicating with the network device by using the second parameter includes: and the terminal adopts the second parameter to communicate with the network equipment when the timer period is overtime.

The terminal starts a timer at the terminal side when sending the RRC connection reconfiguration complete message, which can be understood as that the terminal starts the timer after submitting the RRC connection reconfiguration complete message to the bottom layer, and the timer is expired, namely, the terminal and the network device communicate by adopting the second parameter from the overtime moment or from the overflow moment, namely, the terminal and the network device communicate by adopting the consistent second parameter, so that the call drop rate of the communication between the network device and the terminal is reduced, and the reliability of the configuration parameter is improved.

In some possible implementation manners, the set duration of the timer is a unit of a period of transmitting a physical uplink shared channel PUSCH, a period of transmitting a physical downlink shared channel PDSCH, or a period of transmitting a physical downlink control channel PDCCH between the terminal and the network device.

The set duration of the timer may be in units of a period of a PUSCH, a period of a PDSCH, or a period of a PDCCH, that is, the embodiment of the present application may be applied to different scenarios, so that flexibility of application is improved.

In some possible implementations, in a case that data transmission is scheduled through the PDCCH, a set duration of the timer is a unit of a period in which the PDCCH is transmitted between the terminal and the network device; and under the condition that the data is transmitted through the pre-configured resource, the set duration of the timer is in a unit of the period of transmitting the PUSCH and/or the PDSCH between the terminal and the network equipment.

In the data transmission between the terminal and the network equipment, the set time length units of the timer can be different in the scheduled scene or the non-scheduled scene, so that the embodiment of the application can be applied to different scenes, and the timer can adopt the proper time length units in different scenes, so that the terminal and the network equipment can communicate by adopting the second parameter at more consistent time, and the call drop rate of the communication between the network equipment and the terminal is further reduced.

In some possible implementations, the RRC connection reconfiguration message carries the set duration of the timer.

The setting time of the timer is carried in the RRC connection reconfiguration message, so that the situation that the network equipment sends a special signaling to configure the setting time of the timer is avoided, and the signaling overhead is reduced.

In some possible implementations, the terminal may start a timer when receiving the RRC connection reconfiguration message using the first parameter, and before the timer expires, if the terminal fails to send the RRC connection reconfiguration complete message, the terminal may also resend the RRC connection reconfiguration complete message using the first parameter.

The terminal starts a timer when receiving the RRC connection reconfiguration message by using the first parameter, and if the terminal does not successfully complete the reconfiguration of the RRC connection reconfiguration message according to the RRC connection reconfiguration message received in step 401, the terminal does not feed back the RRC connection completion message to the network device. Accordingly, the network device does not receive the RRC connection reconfiguration complete message within the preset time period, and can resend the RRC connection reconfiguration complete message to the terminal, so that the terminal can receive the RRC connection reconfiguration message again by using the first parameter until the parameter reconfiguration is completed, and send the RRC connection reconfiguration complete message to the network device, thereby improving the probability of successful transmission of the RRC connection reconfiguration message, and further reducing the call drop rate of communication between the network device and the terminal.

In some possible implementations, a timing unit of the timer is a period of transmitting a physical uplink shared channel PUSCH, a physical downlink shared channel PDSCH, or a physical downlink control channel PDCCH between the terminal and the network device.

The timer of the embodiment of the application may be a period for receiving and sending signaling or data between the terminal and the network device, so that the terminal and the network device may use a consistent timing unit, and the terminal and the network device use the second parameter to perform time alignment of communication, thereby further reducing a call drop rate.

In some possible implementations, the method further includes: the terminal receives an RRC connection reconfiguration complete confirmation message, wherein the RRC connection reconfiguration complete confirmation message is used for indicating the network equipment to receive the RRC connection reconfiguration complete message; after sending the RRC connection reconfiguration complete message, the terminal communicating with the network device by using the second parameter includes: and after the terminal receives the RRC connection reconfiguration completion confirmation message, the terminal adopts the second parameter to communicate with the network equipment.

After sending the RRC connection reconfiguration complete message, the terminal may wait for receiving an RRC connection reconfiguration complete confirmation message sent by the network device, and after receiving the RRC connection reconfiguration complete confirmation message, start to communicate with the network device using the second parameter. Correspondingly, after receiving the RRC connection reconfiguration complete message, the network device sends an RRC connection reconfiguration complete confirmation message to the terminal device, and starts to communicate with the terminal by using the second parameter after sending the RRC connection reconfiguration complete confirmation message. Therefore, the network equipment is ensured to determine that the terminal receives the RRC connection reconfiguration message indicating the second parameter, and the terminal also determines that the network equipment receives the RRC connection reconfiguration completion message, so that the terminal and the network equipment can communicate by adopting the consistent second parameter, and the call drop rate of communication between the terminal and the network equipment is further reduced.

In some possible implementations, the method further includes: the terminal sends a feedback message of the RRC connection reconfiguration complete confirmation message to the network device, where the feedback message is used to indicate whether the terminal receives the RRC connection reconfiguration complete confirmation message.

The feedback message may include ACK and NACK, and the feedback message is ACK after the terminal receives the RRC connection reconfiguration complete confirmation message, and NACK after the terminal does not receive the RRC connection reconfiguration complete confirmation message. And the network equipment adopts the second parameter to communicate with the terminal under the condition that the received feedback message is ACK. In addition, the message length of the feedback message of the RRC connection reconfiguration completion confirmation message is smaller, the overhead for transmitting the feedback message is smaller, and the overhead for the network equipment to identify the feedback message is also smaller, namely the communication overhead is saved.

In some possible implementations, the method further includes: the terminal receives indication information after sending an RRC connection reconfiguration complete message, wherein the indication information is used for indicating the starting moment of communication with the network equipment by adopting a second parameter; after sending the RRC connection reconfiguration complete message, the terminal communicating with the network device by using the second parameter includes: and the terminal communicates with the network equipment by adopting the second parameter from the starting time.

The network device and the terminal use the first parameter to communicate before the starting time, and can use the second parameter to communicate from the time indicated by the indication information as the starting time, that is, the time points of the second parameter in the devices at the two ends of communication are the same, thereby further ensuring the reliability of communication and reducing the call drop rate.

In some possible implementations, the receiving, by the terminal, the indication information includes receiving, by the terminal, a media access control layer control element, MAC CE, where the MAC CE carries the indication information.

The indication information can be carried in the MAC CE, thereby avoiding the network equipment from specially sending the indication information and reducing the signaling overhead.

In some possible implementations, the starting time is a time domain resource number.

The network equipment adopts the first parameter to send the RRC connection reconfiguration message for indicating the second parameter, receives the RRC connection reconfiguration completion message for responding to the RRC connection reconfiguration message, and adopts the second parameter to communicate with the terminal after receiving the RRC connection reconfiguration completion message.

The network device starts a timer on the network device side when receiving the RRC connection reconfiguration complete message, that is, the network device uses the second parameter for communication from the timeout time or from the overflow time. If the terminal starts the timer at the terminal side when the RRC connection reconfiguration completion message is sent, the terminal and the network equipment are facilitated to communicate by adopting the consistent second parameter, the call drop rate of communication between the network equipment and the terminal is reduced, and the reliability of the configuration parameter is improved.

In the data transmission between the network device and the terminal under the scheduling scene or under the non-scheduling scene, the set time length units of the timer can be different, so that the embodiment of the application can be applied to different scenes, and the timer can adopt the proper time length units in different scenes, so that the terminal and the network device adopt the second parameter for communication through more consistent time, and the call drop rate of the communication between the network device and the terminal is further reduced.

For example, the NB includes only one Resource Block (RB), i.e., the bandwidth of the NB is only 180 KB. The method of the embodiment of the application can effectively solve the problem of congestion of the mass terminals in the IOT technology when the mass terminals access the network through the NB.

Fig. 1 is a schematic diagram of a communication system of the present application. The communication system in fig. 1 may include at least one terminal (e.g., terminal 10, terminal 20, terminal 30, terminal 40, terminal 50, and terminal 60) and a network device 70. The network device 70 is configured to provide a communication service to a terminal and access a core network, and the terminal may access the network by searching for a synchronization signal, a broadcast signal, and the like transmitted by the network device 70, thereby performing communication with the network. The terminals 10, 20, 30, 40 and 60 in fig. 1 may perform uplink and downlink transmissions with the network device 70. For example, the network device 70 may transmit a downlink signal to the terminal 10, the terminal 20, the terminal 30, the terminal 40, and the terminal 60, or may receive an uplink signal transmitted by the terminal 10, the terminal 20, the terminal 30, the terminal 40, and the terminal 60.

The terminal 40, the terminal 50, and the terminal 60 may be regarded as one communication system, and the terminal 60 may transmit a downlink signal to the terminal 40 and the terminal 50 or may receive an uplink signal transmitted by the terminal 40 and the terminal 50.

Fig. 2 shows a schematic flow chart of a method of signal transmission of a conventional scheme.

201, a terminal sends (message, MSG)1 to a network device, namely, initiates random access;

202, the network device sends a response message of the MSG1, that is, a Message (MSG) 2, to the terminal, where the MSG2 includes a Timing Advance (TA) and an uplink resource;

203, the terminal sends a Radio Resource Control (RRC) connection establishment request (connection request) to the network device on the uplink resource according to the TA;

204, the network device sends a conflict resolution message (or referred to as RRC connection setup message) to the terminal, the conflict resolution message being used for indicating that the random access is successful;

205, the terminal sends an RRC connection setup complete message to the network device after winning the collision;

206, after receiving the RRC connection setup complete message, the network device sends an RRC connection reconfiguration message to the terminal, and the network device takes effect of the new configuration parameters indicated in the RRC connection reconfiguration message immediately after sending the RRC connection reconfiguration message;

207, the terminal also takes effect of the new configuration parameters indicated in the RRC connection reconfiguration message immediately after receiving the RRC connection reconfiguration message;

and 208, the terminal sends an RRC connection reconfiguration complete message by using the new configuration parameters.

In conventional solutions, the network device takes effect of the new configuration parameters immediately after the sending step 206. However, a certain error rate or block error rate may exist in a Physical Downlink Shared Channel (PDSCH) carrying the RRC connection reconfiguration message during transmission, that is, the terminal may not receive the RRC connection reconfiguration message, as shown in fig. 3. In this way, the network device already communicates with the terminal using the new configuration parameters, and the terminal still communicates using the original configuration parameters, so that the communication between the network device and the terminal is dropped due to the inconsistency of the configuration parameters.

Fig. 4 shows a schematic flow chart of a method of parameter reconfiguration of an embodiment of the present application.

401, the terminal receives an RRC connection reconfiguration message using the first parameter, where the RRC connection reconfiguration message is used to indicate the second parameter. Accordingly, the network device sends the RRC connection reconfiguration message using the first parameter.

Specifically, the terminal uses the first parameter to communicate with the network device, as shown in fig. 2 before step 205. In this embodiment of the present application, the terminal receives an RRC connection reconfiguration message by using the first parameter, where the RRC connection reconfiguration message is used to indicate a new configuration parameter (i.e., a second parameter), that is, the network device configures the second parameter for the terminal through the RRC connection reconfiguration message.

It should be understood that the receiving of the RRC connection reconfiguration message using the first parameter means receiving the RRC connection reconfiguration message using the configuration before the RRC connection reconfiguration, and the second parameter is a new configuration parameter in the RRC connection reconfiguration message.

It should be understood that the parameters may include time-frequency code resources, and may also include port numbers, and the like, which is not limited in this application. I.e. the first parameter and the second parameter may be different in at least one of the included time-frequency resources and port numbers.

The first parameter and the second parameter may also be downlink transmission mode configuration, uplink transmission mode configuration, downlink resource configuration (such as Physical Downlink Control Channel (PDCCH), Physical Downlink Shared Channel (PDSCH)), transmission repetition frequency configuration, resource position configuration, PDCCH dedicated configuration, uplink non-scheduling configuration, and downlink non-scheduling configuration (such as PDSCH transmission carrier configuration, transmission interval, repetition frequency configuration); a multiple hybrid automatic retransmission request (HARQ) configuration, a 2HARQ process configuration, a 4HARQ process configuration, a security configuration, a frame structure configuration, and the like.

Optionally, the terminal performs parameter reconfiguration for the terminal according to the second parameter indicated in the RRC connection reconfiguration message.

402, after completing the reconfiguration parameter, the terminal sends an RRC connection reconfiguration complete message using the first parameter. Correspondingly, the network device receives the RRC connection reconfiguration complete message by adopting the first parameter.

Specifically, the terminal sends an RRC connection reconfiguration complete message to the network device, that is, the RRC connection reconfiguration complete message indicates that the terminal has received the second parameter.

In an embodiment, the terminal may start a timer when receiving the RRC connection reconfiguration message using the first parameter, and may also resend the RRC connection reconfiguration complete message using the first parameter if the terminal fails to send the RRC connection reconfiguration complete message before the timer expires.

Specifically, the terminal starts the timer when receiving the RRC connection reconfiguration message by using the first parameter, and if the terminal does not successfully complete the reconfiguration of the RRC connection reconfiguration message according to the RRC connection reconfiguration message received in step 401, the terminal does not feed back the RRC connection completion message to the network device. Accordingly, the network device does not receive the RRC connection reconfiguration complete message within the preset time period, and can resend the RRC connection reconfiguration complete message to the terminal, so that the terminal can receive the RRC connection reconfiguration message again by using the first parameter until the parameter reconfiguration is completed, and send the RRC connection reconfiguration complete message to the network device, thereby improving the probability of successful transmission of the RRC connection reconfiguration message, and further reducing the call drop rate of communication between the network device and the terminal.

It should be understood that, during the timer period, the network device may retransmit the RRC connection reconfiguration message once or multiple times, which is not limited in this application.

Optionally, the terminal communicates with the network device using the second parameter after the timer expires.

Optionally, the network device starts a timer on the network device side when receiving the RRC connection reconfiguration complete message, and communicates with the terminal using the second parameter after the timer expires.

In another embodiment, the terminal starts a timer when sending an RRC connection reconfiguration complete message. Accordingly, the network device also starts a timer upon receiving the RRC connection reconfiguration complete message.

Specifically, the terminal starts a timer at the terminal side when sending the RRC connection reconfiguration complete message, which may be understood as that the terminal starts the timer after submitting the RRC connection reconfiguration complete message to the bottom layer, and the network device starts the timer at the network device side when receiving the RRC connection reconfiguration complete message, and performs communication by using the second parameter when the timer expires, that is, from the timeout time or from the overflow time, that is, the terminal and the network device perform communication by using the second parameter, which is consistent with each other, so that a call drop rate of communication between the network device and the terminal is reduced, and reliability of the configuration parameter is improved.

It should be understood that the specific start timer starts at layer 3, layer 2 or layer 1 depending on the UE implementation.

It should also be understood that the time length set by the timer at the terminal side and the timer at the network device side may be the same, i.e. the time length for the terminal to send the RRC connection reconfiguration complete message is ignored. Or the time length of the RRC connection reconfiguration completion message interacted between the terminal and the network equipment is detected in advance, and the time length of the timer at the terminal side is set to be longer than the time length of the timer at the network equipment side by the pre-measured time length, so that the terminal side and the network equipment side can adopt the second parameter for communication at the same time.

Optionally, the duration set by the timer in the embodiment of the present application may be a unit of a period for receiving and sending signaling or data between the terminal and the network device.

Specifically, the period of signaling transmitted and received between the terminal and the network device may be a period of a PDCCH carrying signaling in a scheduling scenario, or a period of a Physical Uplink Shared Channel (PUSCH) or a PDSCH carrying signaling in a non-scheduling scenario.

The period of data transceived between the terminal and the network device may be a period of a PUSCH or PDSCH carrying data.

For example, the duration of the timer may be set to 5 or 8 transmission periods (PUSCH or PDSCH periods or PDCCH scheduling periods).

Optionally, the set duration of the timer may be configured through an RRC connection reconfiguration message. The name of the timer may be T120, which is not limited herein.

Specifically, for a scheduled transmission scenario, the set duration of the timer may be in units of transmission periods of the PDCCH, and for an unscheduled transmission scenario, the set duration of the timer may be in units of transmission periods of the PUSCH or transmission periods of the PDSCH. Scheduled transmission means data transmission (uplink data transmission or downlink data transmission) performed through resources scheduled by the PDCCH. The non-scheduling scenario is that the network device pre-configures resources for the terminal, and the terminal and the network device directly perform PDSCH and/or PUSCH transmission on the pre-configured resources. The non-scheduled transmission does not rely on the scheduling of the PDCCH. The resource pre-configured by the network is a resource configured by an RRC message or other media access control layer control element (MAC CE).

It should be noted that the transmission period of the data or the signaling may be configured in advance by the network device, or may be agreed by the protocol, or may be a default fixed value of the network device and the terminal, such as default 5 transmission periods. This is not limited in this application.

And 403, after sending the RRC connection reconfiguration complete message, the terminal communicates with the network device using the second parameter. Accordingly, the network device communicates with the terminal using the second parameter.

In particular, the communication between the network device and the terminal may specifically be the sending of signaling and/or data or the receiving of signaling and/or data. The terminal receives an RRC connection reconfiguration message used for indicating a second parameter by adopting a first parameter, performs reconfiguration of the second parameter, sends an RRC connection reconfiguration complete message to the network equipment by adopting the first parameter after the reconfiguration of the second parameter is completed, communicates with the network equipment by adopting the second parameter after the RRC connection reconfiguration complete message is sent, and thus the problem that the use parameters of a transceiving end are inconsistent due to the fact that the terminal still uses the first parameter to communicate with the network equipment when the terminal does not successfully receive the RRC connection reconfiguration message and the network equipment still uses the second parameter to communicate with the terminal after the network equipment sends the RRC connection reconfiguration message is avoided, namely, the network equipment determines that the terminal receives the RRC connection reconfiguration message through the received RRC connection reconfiguration complete message, and then the network equipment and the terminal communicate through the second parameter, thereby reducing the dropped call rate of the communication between the terminal and the network equipment.

It should be noted that, in the embodiment of the present application, starting the corresponding operation after sending a message may be starting the operation immediately when sending the message, or starting the operation after a preset time period expires after sending the message. For example, the terminal immediately adopts the newly validated second parameter after sending the RRC connection reconfiguration complete message, or may adopt the newly validated second parameter after a preset time period, which is not limited in the present application.

Optionally, after sending the RRC connection reconfiguration complete message, the terminal may further receive an RRC connection reconfiguration complete confirmation message sent by the network device, and after receiving the RRC connection reconfiguration complete confirmation message, the terminal may communicate with the network device by using the second parameter.

Specifically, after sending the RRC connection reconfiguration complete message, the terminal may wait for receiving the RRC connection reconfiguration complete confirmation message sent by the network device, and after receiving the RRC connection reconfiguration complete confirmation message, start to communicate with the network device using the second parameter. Correspondingly, after receiving the RRC connection reconfiguration complete message, the network device sends an RRC connection reconfiguration complete confirmation message to the terminal device, and starts to communicate with the terminal by using the second parameter after sending the RRC connection reconfiguration complete confirmation message. Therefore, the network equipment is ensured to determine that the terminal receives the RRC connection reconfiguration message indicating the second parameter, and the terminal also determines that the network equipment receives the RRC connection reconfiguration completion message, so that the terminal and the network equipment can communicate by adopting the consistent second parameter, and the call drop rate of communication between the terminal and the network equipment is further reduced.

It should be noted that, the network device may perform steps 401 and 402 by L3 layer or L2 layer of the network device, and the network device may also transmit the RRC connection reconfiguration complete confirmation message by L3 layer of the network device.

Optionally, after receiving the RRC connection reconfiguration complete confirmation message, the terminal may further send a feedback message of the RRC connection reconfiguration complete confirmation message to the network device, where the feedback message is used to indicate whether the terminal receives the RRC connection reconfiguration complete confirmation message.

Specifically, the feedback message may include an Acknowledgement (ACK) message and a Negative Acknowledgement (NACK) message, where the feedback message is ACK after the terminal receives the RRC connection reconfiguration complete acknowledgement message, and the feedback message is NACK after the terminal does not receive the RRC connection reconfiguration complete acknowledgement message. And the network equipment adopts the second parameter to communicate with the terminal under the condition that the received feedback message is ACK. And the network equipment adopts the first parameter to communicate with the terminal under the condition that the received feedback message is NACK. In addition, the message length of the feedback message of the RRC connection reconfiguration completion confirmation message is smaller, the overhead for transmitting the feedback message is smaller, and the overhead for the network equipment to identify the feedback message is also smaller, namely the communication overhead is saved.

It should be noted that the layer L2 of the network device may receive the feedback message and the layer L2 performs validation of the second parameter.

Optionally, after receiving the RRC connection reconfiguration complete message, the network device may further send indication information, where the indication information is used to indicate a starting time of communicating with the terminal using the second parameter, and after receiving the indication information, the terminal starts to communicate with the network device using the second parameter from the starting time indicated by the indication information, and accordingly, the network device also starts to communicate with the terminal using the second parameter from the starting time indicated by the indication information.

Specifically, the network device and the terminal use the first parameter for communication before the start time, and the time indicated by the indication information can be used as the start time to use the second parameter for communication, that is, the time points at which the second parameter takes effect in the devices at both ends of communication are the same, thereby further ensuring the reliability of communication and reducing the call drop rate.

Alternatively, the starting time may be an absolute time point, or may be a time interval relative to the transceiving time.

It should be noted that, the network device may send the indication information to the terminal, where the L3 layer of the network device starts the validation second parameter from the L2 layer of the terminal through the L2 layer that can be provided to the terminal on the L2 layer.

Alternatively, the starting time may be a time domain resource number.

Specifically, the time domain resource may be at least one of a frame, a radio frame, a subframe, a slot, a mini-slot, and an Orthogonal Frequency Division Multiplexing (OFDM) symbol. Accordingly, the time domain resource number is the corresponding number of the corresponding time domain resource. For example, it may be a subframe number.

Optionally, the indication information may be carried in a Media Access Control (MAC) control element (MAC CE), so as to avoid that the network device specially transmits the indication information, and reduce signaling overhead.

Therefore, in the method for parameter reconfiguration according to the embodiment of the present application, the terminal receives an RRC connection reconfiguration message indicating a second parameter by using a first parameter, performs reconfiguration of the second parameter, sends an RRC connection reconfiguration complete message to the network device by using the first parameter after completing reconfiguration of the second parameter, and communicates with the network device by using the second parameter after sending the RRC connection reconfiguration complete message, so as to avoid a problem that a parameter used by a transceiving end is inconsistent due to that the network device communicates with the terminal by using the second parameter after sending the RRC connection reconfiguration complete message without successfully receiving the RRC connection reconfiguration message, that is, the network device determines that the terminal receives the RRC connection reconfiguration message by using the received RRC connection reconfiguration complete message, and then the network equipment and the terminal communicate through the second parameter, so that the call drop rate of the communication between the terminal and the network equipment is reduced.

Fig. 5 shows a schematic flow chart of a method of parameter reconfiguration according to another embodiment of the present application.

It should be noted that the same terms as those in the foregoing embodiments in the present application mean the same meanings, unless otherwise specified.

And 501, the terminal determines that the feedback message is a confirmation response message or a negative response message according to whether the RRC connection reconfiguration message is received by adopting the first parameter, wherein the RRC connection reconfiguration message is used for indicating the second parameter.

Specifically, if the terminal receives the RRC connection reconfiguration message, the feedback message is an acknowledgement message. And if the terminal does not receive the RRC connection reconfiguration message, the feedback message is a negative response message.

Optionally, the terminal uses the first parameter for communication when the feedback message is a negative response message, and re-receives the RRC connection reconfiguration message using the first parameter. Accordingly, the network device uses the first parameter to communicate when the received feedback message is a negative response message, and repeatedly sends the RRC connection reconfiguration message.

502, the terminal sends the feedback message by using the first parameter. Accordingly, the network device receives the feedback message.

And 503, when the feedback message is a confirmation response message, the terminal communicates with the network device by using the second parameter.

Therefore, in the method for parameter reconfiguration according to the embodiment of the present application, the terminal determines whether the feedback message is a confirm response message or a negative response message according to whether the RRC connection reconfiguration message can be received by using the first parameter, and communicates with the network device by using the second parameter when the feedback message is the confirm response message; and under the condition that the feedback message is a negative response message, the RRC connection reconfiguration message is received again by using the first parameter until the RRC connection reconfiguration message is received, the confirmation response message is sent, and then the second parameter is adopted to communicate with the network equipment, so that the call drop rate of the communication between the terminal and the network equipment is reduced.

The method for parameter reconfiguration according to the embodiment of the present application is described above in detail, and the apparatus for parameter reconfiguration according to the embodiment of the present application will be described below.

Fig. 6 shows a schematic block diagram of an apparatus 600 for parameter reconfiguration according to an embodiment of the present application.

It is to be understood that the apparatus 600 may correspond to the terminal in the embodiment shown in fig. 4, and may have any function of the terminal in the method. The apparatus 600 includes a transceiver module 610 and a processing module 620.

the processing module 620 is specifically configured to:

and when the timer period is overtime, the second parameter is adopted to communicate with the network equipment.

Optionally, the set duration of the timer is a unit of a period for transmitting a physical uplink shared channel PUSCH, a period for transmitting a physical downlink shared channel PDSCH, or a period for transmitting a physical downlink control channel PDCCH between the terminal and the network device.

Optionally, when the resource for data transmission is scheduled through the PDCCH, the set duration of the timer is a unit of a period in which the PDCCH is transmitted between the terminal and the network device;

and under the condition that the resource of data transmission is a pre-configured resource, the set duration of the timer is in a unit of the period of transmitting the PUSCH and/or the PDSCH between the terminal and the network equipment.

Optionally, the RRC connection reconfiguration message carries a set duration of the timer.

Optionally, the transceiver module 610 is further configured to receive an RRC connection reconfiguration complete confirmation message, where the RRC connection reconfiguration complete confirmation message is used to instruct the network device to receive the RRC connection reconfiguration complete message;

Optionally, the starting time is a time domain resource number.

Therefore, the apparatus for parameter reconfiguration according to the embodiment of the present application receives, by using the first parameter, an RRC connection reconfiguration message indicating the second parameter, performs reconfiguration of the second parameter, sends, after completing reconfiguration of the second parameter, an RRC connection reconfiguration complete message to the network device by using the first parameter, and communicates with the network device by using the second parameter after sending the RRC connection reconfiguration complete message, so as to avoid a problem that a transceiver end usage parameter is inconsistent due to the fact that the network device communicates with the terminal by using the second parameter after sending the RRC connection reconfiguration complete message without successfully receiving the RRC connection reconfiguration message, that is, the network device determines that the terminal receives the RRC connection reconfiguration message by using the received RRC connection reconfiguration complete message, and then the network equipment and the terminal communicate through the second parameter, so that the call drop rate of the communication between the terminal and the network equipment is reduced.
