Description

Communication processing method, device, user equipment and storage medium

Technical Field

The present application relates to the field of communications technologies, and in particular, to a communication processing method and apparatus, a user equipment, and a storage medium.

Background

With the development of communication technology, communication modes between a base station and User Equipment (UE) and between the UE and the UE appear. The communication mode may be based on different channels, for example, a first Channel (e.g., Dedicated Traffic Channel, DTCH) is used between the ue and the base station, and a second Channel (e.g., sidelink Traffic Channel, STCH) is used between the ue and the base station.

Generally, a user equipment can communicate with a base station and other user equipments respectively by using different channels; after the communication between the user equipment and the base station is finished, if necessary, the user equipment can continue to communicate with other user equipment. However, in the conventional communication field, all channels of the ue may share radio resources, so that if the ue enters a poor signal area, the ue cannot parse the message sent by the data base station, and thus the used radio resources are released when the timer expires, which causes other communications between ues to be forced to end. If the ue still wants to communicate with other ues, it needs to request radio resources again, which results in large signaling consumption.

Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.

Reference in the specification to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the specification. The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.

The application scenario for which a communication processing method is provided may be as shown in fig. 1, where a first user equipment and a second user equipment may be vehicles, each vehicle may also communicate with a base station, and the vehicles may communicate with each other; the channel used for the inter-vehicle communication and the channel used for the inter-vehicle and base station communication are different from each other, and will be referred to as a first channel and a second channel in the following description.

The first channel can be a side chain service channel, and direct communication between vehicles is realized; the second channel may be a dedicated traffic channel enabling communication between the vehicle and the base station. Furthermore, when the vehicle uses the first channel and the second channel to communicate with other vehicles and the base station respectively, the used interfaces are different; for example, the interface for the sidelink traffic channel is the PC5 interface and the interface for the dedicated traffic channel is the Uu interface.

Before the first user equipment utilizes the channel to carry out communication, the first user equipment needs to configure wireless resources used by the channel to be communicated; after the first user equipment configures the radio resources, the first user equipment is in a radio resource control CONNECTED state (namely RRC _ CONNECTED); the above-described radio resources are mainly used for transmitting (transmitting/receiving) data of a channel to be communicated. The first user equipment may configure, when configuring the radio resource, available radio signal waves for receiving/transmitting data of the channel, a timer for monitoring a data activity state of the channel, and the like.

Referring to fig. 2, the communication processing method provided in the present application is described by taking the method as an example applied to a first user equipment, where a communication channel between the first user equipment and a second user equipment is referred to as a first channel, and a communication channel between the first user equipment and a base station is referred to as a second channel; the method mainly comprises the following steps:

step S201, under the condition that the first channel is detected to be in a data activity state, allocating a first wireless resource for the first channel;

the data activity state of a channel may be understood as that there is data to be transmitted on the channel, for example, the first user equipment prepares to send data to the second user equipment on the first channel, or the second user equipment prepares to send data to the first user equipment on the first channel. The data active state may be understood as any state of the channel currently in which data can be transmitted for data communication, i.e. the channel may be considered to be in the data active state as long as the channel can complete the data communication operation, regardless of whether data communication is in progress or not. The radio resources may include radio signal waves used for transmitting (transmitting or receiving) data, and before the channel is communicated, the available radio resources need to be configured for the channel, and then the data of the channel is transmitted by using the configured radio resources. The Radio resources to be configured may mainly include Radio Bearer (RB, Radio Bearer; e.g., SRB, DRB) establishment.

If the first user equipment detects that there is data to be transmitted (data to be transmitted or data to be received) in the first channel, the first user equipment may configure corresponding radio resources (i.e., first radio resources) for the first channel, so as to transmit (i.e., send or receive) the data to be transmitted on the first channel by using the first radio resources.

Step S202, the first channel is controlled through the first wireless resource, and data transmission is carried out under the condition that the second channel is in any state.

In this step, during the data transmission process of the first user equipment on the first channel by using the first radio resource, the channel (i.e. the second channel) between the first user equipment and the base station may be in a data active state or a data inactive state; the first user equipment still utilizes the first radio resource to perform data transmission on the first channel no matter the second channel is in a data active state or a data inactive state.

In the communication processing method, when the second channel is in any state, the data transmission of the first channel is controlled through the first radio resource allocated to the first channel, so that the stable transmission of the first channel can be maintained, the data transmission interruption of the first channel caused by the state of the second channel is avoided, and the signaling loss is reduced.

In one embodiment, the first radio resource includes a first timer. When the first user equipment performs the step of allocating the first radio resource to the first channel, the following steps may be specifically performed: a first timer is assigned for a first channel. The first user equipment may further perform the steps of: a second timer is assigned for the second channel, wherein the first timer and the second timer are different. When the first user equipment executes step S202, the method specifically includes: data transmission on the first channel is controlled via the first radio resource and data transmission on the second channel is controlled via the second radio resource.

Wherein the radio resource may include a timer in addition to the radio signal wave. The timer is used for monitoring whether the corresponding channel is in a data inactivity state; for example, if the timing duration reaches the timing duration of the timer (i.e., the timer expires), and there is no data to be transmitted/sent in the channel, it indicates that the channel is in a data inactive state; for another example, if a channel has data to be transmitted within the timing duration of the timer, indicating that the channel is in a data active state, the timer may be re-timed to determine whether the channel is in a data inactive state within the timing duration since the re-timing.

In the above embodiment, different timers are configured for the first channel and the second channel, and data activity states of the first channel and the second channel are monitored respectively; if the second channel is in a data inactivity state, which causes the second timer to expire, even if the second timer expires, the second timer will not interfere with the monitoring of the first channel by the first timer, and it is ensured that the first user equipment can continue data transmission with the second user equipment on the first channel based on the radio signal wave.

Further, if the second timer expires, in order to ensure the utilization rate of the radio resource, the first user equipment may also release the radio resource corresponding to the second channel.

Further, the first user equipment may be a proximity service (Prose) enabled user equipment. The condition that the first timer is restarted is that data/communication interaction to be transmitted aiming at the first channel exists on a medium access control layer.

The mac layer is a mac (medium Access control) layer, and is mainly used for data transmission and scheduling radio resources. Introducing a first channel as a side chain service channel: if the data transmission/data reception of the side chain service channel occurs in the MAC layer, which indicates that the MAC layer has communication interaction with the side chain service channel, the first user equipment restarts the first timer, and restarts the data inactivity state monitoring of the communication of the side chain service channel.

Further, if the first user equipment is configured with the first timer, the first user equipment may further perform the following steps: and if the first timer expires, triggering the media access control layer to report a message of the expiration of the first timer to the radio resource control layer so as to release the first radio resource.

Since the restart of the first timer is when the communication interaction of the first channel (such as the sidelink traffic channel) occurs on the MAC layer, if the first timer expires, it indicates that the communication interaction has not occurred on the first channel for a long time, and the first channel is in a data inactive state, which may indicate that the communication of the first channel is ended. At this time, the MAC layer may report a message indicating that the first timer expires to a radio resource control layer (RRC layer) of an upper layer, so as to release the first radio resource, effectively release the corresponding radio resource when the communication of the first channel is ended, avoid the occupation of the radio resource, and improve the utilization rate of the radio resource.

The above processing is described with reference to fig. 3: step S301, performing side-chain traffic channel, D2D (Device to Device Communication) or D2X (Vehicle to evolution, information exchange between Vehicle and outside world) Communication between the first user equipment and the second user equipment based on a PC5 interface; step S302, whether the MAC layer has the receiving/sending of the MAC SDU data of the side chain service channel; if yes, restarting the first timer (step S303); if not, step S304 is executed, in which the MAC layer indicates the first timer to expire to the upper RRC layer, and executes an operation of leaving the RRC _ CONNECTED mode and releases the corresponding radio resource.

In one embodiment, the first radio resource includes a first timer and/or a third timer. When the first user equipment allocates the first radio resource to the first channel, the following steps may be specifically executed: a third timer is assigned to the first channel and the second channel. When the first user equipment executes step S202, the method may specifically include: sending a first message to the network through the first user equipment before the third timer expires, and controlling data transmission on the first channel and the second channel through the third timer while the second channel is in a data active state; wherein the first message is used to indicate that the first channel is in a data active state.

Wherein, the first channel and the second channel are respectively distributed with a third timer, and the monitoring of the data activity state of the first channel and the second channel is carried out by using the same timer.

In this case, before the third timer expires, if there is data to be transmitted on the first channel, it indicates that the first channel is in a data active state; if the second channel also has data to be transmitted, the second channel is also in a data active state; at this time, the first user equipment sends a first message to the network so that the network knows that the first channel is in a data activity state and restarts the third timer; the first user equipment may also restart the third timer and transmit data of the first channel and the second channel using the radio signal wave.

Further, the first user equipment sends the first message to the network, so that when the network learns that the first channel is in the data active state and restarts the third timer, the following method may be specifically implemented: the first user equipment sends a keep-alive data packet to the network, so that the network keeps in a radio resource control connection state after receiving the keep-alive data packet.

Wherein, the keep-alive packet is a keep alive packet, which may be a PING (internet packet explorer) packet; the first user equipment, if sending the keep-alive packet to the network, may cause data transmission to occur at the MAC layer for the first/second channel, facilitating a timing restart of the third timer of the network and the first user equipment.

In addition, when the first user equipment executes step S202, the following steps may be specifically executed: determining that the second channel is in a data inactivity state under the condition that the third timer expires, allocating and starting a first timer for the first channel through the network under the condition that the second channel is in the data inactivity state, and controlling data transmission on the first channel through the first timer; the first timer is the same as or different from the third timer.

That is, if there is no data to be transmitted within the timing duration of the second channel, the third timer expires, indicating that the second channel is in a data inactive state. If the first channel has data to be transmitted while the second channel is in the data inactivity state, the first user equipment may restart the third timer for the first channel through the network, and then the first user equipment monitors data transmission on the first channel using the third timer. In addition, when the second channel is in a data inactivity state, if the first channel has data to be transmitted, the first user equipment may also allocate a first timer different from the third timer to the first channel through the network, and the first timer monitors data transmission on the first channel.

In the above embodiment, even if the first channel and the second channel share the same timer, in the case that the same timer expires subsequently, the first user equipment continues to monitor the data transmission of the first channel by using the same timer, or allocates another timer to monitor the data transmission of the first channel, so as to ensure that the data transmission of the first channel is performed normally.

Further, the first user equipment may further perform the steps of: when the data service on the second channel is completed, a third timer is started and a second message to disconnect the second channel is sent to the first user equipment over the network. When the first user equipment performs the step of determining that the second channel is in the data inactivity state when the third timer expires, the method specifically includes: and determining to be in a data inactivity state on the second channel in case that the third timer expires and the network does not receive feedback information of the first user equipment based on the second message.

The channel is in a data inactivity state, and the channel can also be in a state that the network does not receive data to be transmitted of the equipment within a set time length; for example, the network does not receive the feedback information of the first user equipment for the second message within the set time length. The data service on a channel can be understood as: since the first user equipment requests data such as video, audio, etc. from the base station, there is a data service on the communication channel between the first user equipment and the base station.

In the above embodiment, if the data such as video requested by the first user equipment to the base station is finished, it indicates that the data service of the second channel is completed; at this time, the base station sends a second message for disconnecting the second channel to the first user equipment through the network; the first user equipment may start a third timer, determine whether a second message is received before the third timer expires, and if the second message is received, the first user equipment feeds back feedback information for the second message to the base station through the network; the network may also start a third timer and determine whether feedback information for the second message intended to be fed back to the base station by the first user equipment is received before the third timer expires. If the third timer expires and the network does not receive the feedback information from the first user equipment, it indicates that the second channel is in a data inactive state.

Therefore, in the above embodiment, the third timer is used to monitor whether the second channel is in a data inactivity state, so as to improve the accuracy of the judgment result, which is beneficial to the subsequent control of the first channel.

In one embodiment, when the first user equipment allocates the first radio resource for the first channel, the following steps may be further performed: periodically allocating a first radio resource to a first channel through a network; or acquiring wireless resource data of the network, and allocating a first wireless resource to the first channel through the network based on the wireless resource data; wherein the first radio resource is not shared with a second radio resource allocated to a second channel by the network.

The first radio resource and the second radio resource may be configured by the network by using the same radio resource control connection reconfiguration instruction, so as to avoid sending the configuration instruction for multiple times and further reduce signaling loss; the RRC Connection Reconfiguration command is an RRC Connection Reconfiguration command for modifying an RRC Connection, such as establishing/releasing/modifying radio resources of a bearer channel.

In the foregoing manner, the first user equipment periodically allocates the first radio resource to the first channel through the network, for example, the first user equipment allocates the first radio resource to the first channel through the network at regular intervals; the radio resource allocated by the fixed period is equivalent to a semi-persistent scheduling radio resource; the interval duration of the periodic allocation may comprehensively consider data indicating a load condition of the radio resource, data indicating an availability condition of the radio resource, a periodic data service, and the like. Since the first radio resource is periodically allocated to the first channel by the network, the first user equipment can be prevented from frequently initiating a radio resource request, and the signaling loss is reduced.

Wherein the radio resource data may include at least one of: load data of the network and available radio resource data of the network. After acquiring wireless resource data of a network, first user equipment determines first wireless resources allocated to a first channel by using the wireless resource data; and in order to avoid mutual interference of the first channel and the second channel, the first radio resource allocated to the first channel and the second radio resource allocated to the second channel are not shared.

Further, when the first user equipment performs the step of acquiring the radio resource data of the network and allocating the first radio resource to the first channel through the network based on the radio resource data, the following steps may be specifically performed: and acquiring the wireless resource data of the network and the grade of the first channel, and allocating the first wireless resource to the first channel through the network based on the wireless resource data and the grade of the first channel.

Wherein, the grade of the channel can be understood as the priority of the channel using the wireless resource; if there are a plurality of channels to which radio resources are currently allocated, one of the channels having a higher rank, the radio resources may be allocated to the channel first.

In the foregoing embodiment, if the first user equipment acquires the radio resource data of the network and the level of the first channel, the level of the first channel is determined to be higher or lower than the level of the other channels to be allocated with radio resources; if the first channel is higher in grade, the first user equipment preferentially allocates a first wireless resource to the first channel; if the first channel is lower in grade, the first user equipment delays to allocate the first radio resource for the first channel.

In the above manner, when allocating the first radio resource to the first channel, the reasonable use of the radio resource can be ensured in combination with the consideration of the level of the first channel.

In order to better understand the above method, an application example of the communication processing method of the present application is described in detail below.

mMTC (massive Machine Type Communication) is one of the key pillars of 5G, while D2D/V2x is a key application. Among other things, sidelink-based communication may enable devices to communicate with each other without base station/network intervention. Wherein, RRC _ CONNECTED is a radio resource control CONNECTED state and belongs to a state of an RRC layer; since the user equipment performing communication interaction needs to utilize radio resources, the user equipment is generally in RRC _ CONNECTED state. In addition, the state of the RRC layer also includes RRC _ IDLE (radio resource control IDLE state), and the user equipment which does not perform communication interaction is generally in RRC _ IDLE.

The user equipment transfers from the RRC _ IDLE mode to the RRC _ CONNECTED mode and performs uplink/downlink data interaction with the base station through the Uu interface, and after completing the service request to the base station, the base station transmits an RRCConnectionRelease message (RRC connection release message) to the user equipment and moves to the RRC _ IDLE mode. However, if the ue is in an environment with weak signals, such as a cell edge/interference area, the ue cannot decode the RRCConnectionRelease message, or the ue sends an uplink message to the base station and does not reach the base station. At this time, according to the 3GPP specification, in order to avoid the state mismatch between the ue and the base station, the data inactivity timer for the dedicated traffic channel is started according to the configured value (from 1 second to 180 seconds), and the data interaction condition on the dedicated traffic channel is monitored.

When the data inactivity timer for the dedicated traffic channel is configured, the user equipment may perform the following operations:

one, start or restart the data inactivity timer for dedicated traffic channels:

if a MAC SDU for DTCH, DCCH (Dedicated Common Control Channel) or CCCH (Common Control Channel) is received on any MAC layer;

if MAC SDUs for DTCH, DCCH or CCCH are transmitted on any MAC layer;

secondly, aiming at the timeout of the data inactivity timer of the special service channel, indicating the timeout condition to the upper RRC layer of the MAC layer:

however, in some scenarios, the user equipment will typically perform uplink/downlink data interaction with the base station over the Uu interface and D2D/sidelink communication with other user equipment over the PC5 interface. If the ue is in a scenario with weak signal and ongoing communication, the ue may not successfully decode the RRCConnectionRelease message sent by the base station, and if the data inactivity timer for the dedicated traffic channel expires, even if the ue is in the sidelink traffic channel communication with other ues, the ue locally releases radio resources and transitions from the RRC _ CONNECTED mode to the RRC _ IDLE mode, which may cause the sidelink traffic channel communication to be interrupted. Therefore, if the ue needs to restart the communication of the sidelink, it needs to acquire a System Information Block (SIB; wherein if it is 5G, the corresponding System Information Block is SIB12/SIB13/SIB 14; and if it is 4G, the corresponding System Information Block is SIB18/SIB19)) from the base station, and further re-initiate a radio resource connection request to perform the communication of the sidelink, which has the problems of high signaling overhead, reduced battery utilization of the ue, and low radio resource utilization efficiency.

First, a,

As shown in fig. 5, in step S1, the first user equipment and the base station perform uplink or downlink data interaction based on the NG/Uu interface, and correspondingly, a dedicated data inactivity timer (equivalent to the second timer) for the dedicated traffic channel of the first user equipment and the base station may be started to monitor the data inactivity condition of the dedicated traffic channel; in addition, the first user equipment is in RRC _ CONNECTED mode;

step S2, the first user equipment and the second user equipment communicate with each other on the PC5 interface through a side chain traffic channel;

step S3, after the service is completed, the base station sends RRCConnectionRelease message to the first user equipment for many times, and the first user equipment fails to decode;

if the network allocates a radio resource for a sidelink traffic channel on the PC5 interface among the dedicated radio resources carrying the uplink or downlink (i.e., corresponding to a dedicated traffic channel), the user equipment continues to use the allocated radio resource to maintain the communication of the sidelink traffic channel and to maintain the RRC _ CONNECTED mode, thereby implementing seamless and efficient sidelink communication, step S4. Wherein the base station may remain in RRC _ CONNECTED mode.

Further, for the user equipment supporting the proximity service, the network may configure a "SL-datainactivity timer monitoring" timer (corresponding to the first timer) in the RRC _ CONNECTED mode, which has a duration from "1 second to 180 seconds", to control a data inactivity operation between the user equipments through the PC5 interface.

After the SL-datainactivity timermonitoring is configured, the ue may perform the following operations:

(1) starting or restarting the SL-DataInactivatyTimermonitoring timer:

if a MAC SDU for the STCH is received on any MAC layer;

if MAC SDU for STCH is transmitted on any MAC layer;

(2) and the SL-DataInactivatyTimeMonitoring timer is overtime, and the overtime condition of the timer is indicated to an upper RRC layer of the MAC layer.

The above-mentioned monitoring of data activity on the sidelink traffic channel between ues by using the SL-datainactivity timer can be understood with reference to fig. 3, and is not described herein again.

The second step,

If the user equipment is performing sidelink communications on the PC5 interface and the data inactivity timer for the dedicated traffic channel times out, the user equipment may transmit a PING packet once before the timeout in order to transmit MAC SDUs for DTCH on the MAC layer, enable starting or restarting of the data inactivity timer for the dedicated traffic channel, and place the base station and the user equipment in the same RRC _ CONNECTED mode, thereby efficiently utilizing radio resources.

Thirdly,

If the network allocates the semi-persistent scheduling resource to the ue for sidelink communication, before releasing the configured semi-persistent scheduling resource, both the ue and the network should determine whether sidelink communication is currently performed, and keep in the RRC _ CONNECTED mode under the condition that it is determined that communication of a sidelink traffic channel is currently performed, thereby achieving effective utilization of radio resources.

In the above embodiment, if the dedicated traffic channel is in the data inactivity state, it indicates that the service between the first user equipment and the base station may be ended and is in the area with weak signals, at this time, the first user equipment continues to use the radio resource of the second channel with the second user equipment, and the second channel is maintained, so as to avoid re-requesting the radio resource of the second channel, reduce signaling loss, and reduce battery loss of the first user equipment; and the first user equipment only releases the wireless resource of the first channel between the first user equipment and the base station, so that the related wireless resource is prevented from being occupied under the condition that the first channel data is inactive, and the availability of the wireless resource is improved.

It should be understood that, although the steps in the flowcharts of fig. 1 to 4 are shown in sequence as indicated by the arrows, the steps are not necessarily performed in sequence as indicated by the arrows. The steps are not performed in the exact order shown and described, and may be performed in other orders, unless explicitly stated otherwise. Moreover, at least a portion of the steps in fig. 1 to 4 may include multiple steps or multiple stages, which are not necessarily performed at the same time, but may be performed at different times, and the order of performing the steps or stages is not necessarily sequential, but may be performed alternately or alternately with other steps or at least a portion of the steps or stages in other steps.
