Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to an information transmission method and a terminal device.
Background
Currently, Radio Resource Control (RRC) messages in a 5G communication system ensure information interaction between a terminal device and a network device. Meanwhile, in order to ensure correct transmission of all RRC messages, an AM mode is used to transmit data in a Radio Link Control (RLC) layer of a terminal device or a network device. In the case that the RLC entity of the terminal device adopts the AM mode, if the RLC entity of the transmitting end has not received the acknowledgement information fed back by the RLC entity of the receiving end with respect to the RLC data (for example, the receiving end receives the erroneous RLC data) after the RLC entity of the receiving end has sent the RLC data to the RLC entity of the receiving end, the RLC entity of the receiving end may notify the RLC entity of the transmitting end to retransmit the RLC data.
In the prior art, when the RLC state variable of the network device is set unreasonably or a network signal jitters, the network device may not successfully receive the RLC data sent by the terminal device, so that the terminal device cannot feed back the acknowledgement information, and the terminal device retransmits the RLC data in a large range. In general, under the condition that an RLC entity of a terminal device adopts an AM mode, if the number of times that the terminal device retransmits the same data is greater than a preset maximum number of times, the terminal device considers that the current network is unavailable, thereby disconnecting the network connection and interrupting service transmission.
However, under the condition that the RLC entity of the terminal device adopts the AM mode, for a data retransmission scenario (for example, a scenario in which the terminal device periodically reports a measurement report to the network device, since the terminal device may periodically send the same measurement report, the measurement report is lost for a certain time, and reporting of the measurement report is not affected), if the retransmission times for retransmitting the same data by the terminal device in the scenario reaches the preset maximum times, the terminal device may still disconnect the network connection, thereby increasing the time delay and reducing the data transmission efficiency.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Some terms involved in the embodiments of the present invention are explained below for convenience of understanding:
1. radio Link Control (RLC) layer
In the 5G NR network mode, data of the user plane and the control panel are transmitted through PDCP/RLC/MAC/RHY. Wherein, the RLC layer is located above the MAC layer and provides segmentation and retransmission services for user and control data, and each RLC entity is configured by RRC.
2. Transmission mode of RLC entity
The RLC entity can be divided into three transmission modes according to the service type, which are: transparent Mode (TM), Unacknowledged Mode (UM), Acknowledged Mode (AM), wherein:
transparent mode: the sending entity does not add any overhead on the higher layer data.
Non-acknowledgement mode: the sending entity adds the necessary control protocol overhead on the higher layer data packets and then transmits but does not guarantee delivery to the peer entity and no retransmission protocol is used. The receiving entity submits the received error data after marking the error data as error or directly discards and reports the error data to a higher layer.
Confirming mode: the transmitting side adds necessary control protocol overhead on the high-level data and then transmits the data and ensures the data to be transmitted to the peer entity. Meanwhile, since the RLC entity has an Automatic Repeat-reQuest (ARQ) capability, if the RLC entity receives an erroneous RLC PDU, the transmitting side RLC is notified to retransmit the PDU. And as the RLC PDU contains sequence number information, the RLC entity also supports in-order/out-of-order delivery of data to higher layers. The service of the confirmation mode comprises the following steps: internet data packets, air interface control signaling, real-time games, etc. Generally, if the retransmission times of the same data retransmission reaches the maximum times, the terminal device triggers the radio link to fail, and the current network is considered to be unavailable to disconnect the network connection, thereby interrupting the service.

Fig. 1 shows a schematic diagram of a possible structure of a communication system according to an embodiment of the present invention. As shown in fig. 1, the communication system includes at least one network device 100 (only one is shown in fig. 1) and one or more terminal devices 200 to which each network device 100 is connected.
The network device 100 may be a base station, a core network device, a Transmission and Reception node (TRP), a relay station, an access Point, or the like. The network device 100 may be a Base Transceiver Station (BTS) in a Global System for Mobile communication (GSM) or Code Division Multiple Access (CDMA) network, or may be an nb (nodeb) in Wideband Code Division Multiple Access (WCDMA), or may be an eNB or enodeb (evolved nodeb) in LTE. The Network device 100 may also be a wireless controller in a Cloud Radio Access Network (CRAN) scenario. The network device 100 may also be a network device in a 5G communication system or a network device in a future evolution network. The words used are not to be construed as limitations of the invention.
The terminal device 200 may be a wireless terminal device or a wired terminal device, and the wireless terminal device may be a device providing voice and/or other service data connectivity to a user, a handheld device with wireless communication function, a computing device or other processing device connected to a wireless modem, a vehicle-mounted device, a wearable device, a terminal device in a future 5G network or a terminal device in a future evolved PLMN network, and the like. A Wireless terminal device may communicate with one or more core networks via a Radio Access Network (RAN), and may be a mobile terminal device, such as a mobile phone (or "cellular" phone) and a computer with a mobile terminal device, for example, a portable, pocket, hand-held, computer-embedded or vehicle-mounted mobile device, which exchanges languages and/or data with the RAN, and Personal Communication Service (PCS) phones, cordless phones, Session Initiation Protocol (SIP) phones, Wireless Local Loop (WLL) stations, Personal Digital Assistants (PDAs), and the like, or a mobile device, a User Equipment (User Equipment, UE), a UE terminal device, an Access terminal device, a Wireless Communication device, A Terminal equipment Unit, a Terminal equipment Station, a Mobile Station (Mobile Station), a Mobile Station (Mobile), a Remote Station (Remote Station), a Remote Station, a Remote Terminal equipment (Remote Terminal), a Subscriber Unit (Subscriber Unit), a Subscriber Station (Subscriber Station), a User Agent (User Agent), a Terminal equipment device, and the like. As an example, in the embodiment of the present invention, fig. 1 illustrates that the terminal device is a mobile phone.
Fig. 2 shows a schematic flow chart of an information transmission method according to an embodiment of the present invention, and as shown in fig. 2, the information transmission method may include the following steps 201 and 202:
step 201: in the case that the transmission mode of the RLC entity of the terminal device is the acknowledged mode, the terminal device determines the transmission mode of the first data to be transmitted.
The transmission mode of the first data to be transmitted includes periodic transmission or aperiodic transmission.
In an example, the first data to be transmitted may be data from an upper layer received by a modem PDCP of the terminal device, and specifically includes: the control plane is from the RRC signaling of the RRC layer and also includes the user plane from the upper layer SDAP packets.
Step 202: if the sending mode of the first data to be sent is periodic sending, the terminal device sets the transmission mode of the RLC entity of the terminal device to an unacknowledged mode, and the first data to be sent is transmitted to the network device through the RLC entity of the terminal device in the unacknowledged mode.
Correspondingly, the opposite-end network equipment still receives the first data to be sent transmitted by the terminal equipment in the confirmation mode.
For example, when the terminal device needs to periodically send data to the network device (for example, the terminal device periodically reports a measurement report to the network device), it indicates that the terminal device does not need to trigger a radio link failure, that is, does not need to disconnect the network connection, so as to increase a time delay of data transmission, at this time, the acknowledged mode of the RLC entity of the terminal device may be set to the unacknowledged mode, the first to-be-sent data is sent in the unacknowledged mode in the RLC layer, and the first to-be-sent data is not retransmitted, so that a radio link failure caused by multiple retransmissions of the first to-be-sent data is reduced.
In a possible example, the step 202 specifically includes: if the sending mode of the first data to be sent is periodic sending and the sending period is less than the first threshold, the transmission mode of the RLC entity of the terminal equipment is set to be an unacknowledged mode, and the first data to be sent is transmitted in the unacknowledged mode through the RLC entity of the terminal equipment.
For example, when the sending period is less than the first threshold, it indicates that the first data to be sent is sent more frequently, and the discarding does not affect the service state of the terminal device.
It should be noted that, the first threshold may be predefined by a user, and the user may flexibly set or modify the first threshold according to an actual application scenario, which is not limited in the present invention. Meanwhile, the first threshold value may also be stored in a memory medium of the terminal device.
In the information transmission method provided in the embodiment of the present invention, when the transmission mode of the RLC entity of the terminal device is the acknowledged mode, the transmission mode of the first to-be-transmitted data is determined, and when the transmission mode is the periodic transmission, the transmission mode of the RLC entity of the terminal device is set to the unacknowledged mode.
Optionally, for the AM mode service, there are some real-time games and data packets for surfing the internet. These data are not required to be completely correct as most RRC messages do, and failure even after multiple RLC retransmissions does not necessarily trigger a radio connection failure. Therefore, it is desirable to avoid triggering radio link failures as much as possible.
In view of the above problems, specific solutions are provided in the embodiments of the present invention.
Illustratively, as shown in fig. 3, after step 201, the method further includes the following step 201a and/or step 201 b:
step 201 a: if the sending mode of the first data to be sent is aperiodic sending and the first data to be sent is service data, the terminal equipment transmits the first data to be sent in the confirmation mode through the RLC entity.
For example, the first Data to be transmitted may be a Packet Data Convergence Protocol (PDCP) Packet Data received by a Packet Data Convergence entity of the terminal device from an upper layer, where the first Data to be transmitted includes RRC signaling of a control plane from an RRC layer, and/or a Data Packet of a user plane from an upper layer SDAP.
For example, when the first to-be-transmitted data is special non-service data, for example, RRC signaling or TCP packet that requires complete accurate feedback, the terminal device disconnects the data connection and reports a radio link failure when the number of retransmissions of the first to-be-transmitted data is greater than a third threshold (that is, the maximum number of retransmissions of data by the RLC entity of the terminal device configured by the network device as described below is, for example, maxretxtxthreshold, which is defined by a protocol and whose value range is { t1, t2, t3, t4, t6, t8, t16, t32}, t1 indicates 1 time, and t32 indicates 32 times).
Illustratively, the service data includes a user plane internet access data packet or a real-time game packet.
Step 201 b: and under the conditions that the first to-be-transmitted data meets the first condition and the second condition, the MAC layer of the terminal equipment does not receive a non-acknowledgement message fed back by the network equipment for the first to-be-transmitted data, and the retransmission frequency of the second to-be-transmitted data is greater than or equal to a second threshold value, the terminal equipment reports the failure of the wireless link, and the connection between the terminal equipment and the network is disconnected.
Wherein the first condition includes: the terminal device successfully sends the first data to be sent, and the terminal device does not receive the acknowledgement message fed back by the network device for the first data to be sent, or the terminal device unsuccessfully sends the first data to be sent, where the second condition is: the retransmission times of the first data to be transmitted are larger than or equal to a second threshold value.
In an example, the second data to be transmitted may be RLC data.
According to the scheme, the current network environment can be further judged according to the retransmission condition of the MAC layer under the RLC layer of the terminal equipment and the transmission condition of other RLC data, the radio link failure is started only under the condition that the current network environment is poor, and the frequency of the radio link failure is effectively reduced.
Illustratively, when an MAC layer under an RLC layer of the terminal device receives an unacknowledged message fed back for first data to be transmitted, it indicates that a current network environment is poor and the whole radio link is in a risk of being disconnected, and if other RLC data in the RLC entity also reaches a maximum retransmission number (i.e., a second threshold), it further indicates that the current network environment is poor and a service needs to be disconnected for radio network reconstruction, and at this time, reporting that the radio link fails and disconnecting the terminal device from the network can save reconstruction time and accelerate radio link reconstruction efficiency.
Further optionally, in the embodiment of the present invention, the step 201a specifically includes the following steps:
step 201a 1: if the sending mode of the first data to be sent is aperiodic sending, the sending period is less than the first threshold value, and the first data to be sent is service data, the terminal equipment transmits the first data to be sent in the confirmation mode through the RLC entity.
Further optionally, in this embodiment of the present invention, the second threshold is smaller than a maximum number of times of retransmission of data by an RLC entity of the terminal device, where the terminal device is configured by the network device. It should be noted that the second threshold may be flexibly set or modified according to an actual application scenario, which is not limited in the present invention, and the second threshold may also be stored in a memory medium of the terminal device.
In the embodiment of the present invention, when the first data to be transmitted is an actual transmission request and does not need to be completely correct data (for example, service data (e.g., real-time game data or internet data packets), and/or the transmission mode is data transmitted periodically (e.g., a periodic reporting measurement report)), the terminal device may set the maximum retransmission number of the data by the RLC entity of the terminal device to the second threshold, and since the second threshold is smaller than the maximum retransmission number specified in the prior art, the terminal device may directly report the radio link failure and disconnect the connection between the terminal device and the network.
