Technical Field

The application belongs to the technical field of communication, and particularly relates to a method and device for exiting a survival time state, a data transmitting end and a readable storage medium.

Background

For a service with a time-to-live requirement, it needs to be ensured that no continuous N times of transmission failures can occur, otherwise, the receiving end application will enter a service unavailable state. In case of failure of consecutive M (M < N) data transmission, the transmitting end enters a Survivin Time (ST) state. In the survival time state, the transmitting end adopts a high-reliability transmission strategy to transmit data so as to expect that the subsequent data packet can be successfully transmitted. However, if the transmitting end is always in the time-to-live state, a large resource overhead will be incurred due to the use of a highly reliable transmission strategy. Therefore, how to make the transmitting end exit from the survival time state is a problem that needs to be solved urgently.

The terms "system" and "network" in embodiments of the present application are often used interchangeably, and the techniques described may be used for both the above-mentioned systems and radio technologies, as well as other systems and radio technologies. The following description describes a New air interface (NR) system for purposes of example and uses NR terminology in much of the description that follows, but these techniques are also applicable to applications other than NR system applications, such as generation 6 (6) ^th Generation, 6G) communication system.

Fig. 1 shows a block diagram of a wireless communication system to which embodiments of the present application are applicable. The wireless communication system includes a terminal 11 and a network device 12. The terminal 11 may also be called a terminal Device or a User Equipment (UE), and the terminal 11 may be a terminal-side Device such as a mobile phone, a tablet (Tablet Personal Computer), a Laptop (Laptop Computer) or a notebook (Personal Digital Assistant, PDA), a palm Computer, a netbook, an ultra-mobile personal Computer (ultra-mobile personal Computer, UMPC), a mobile internet Device (Mobile Internet Device, MID), an augmented reality (augmented reality, AR)/Virtual Reality (VR) Device, a robot, a Wearable Device (VUE), a pedestrian terminal (PUE), a smart home (home Device with a wireless communication function, such as a refrigerator, a television, a washing machine, or furniture, etc.), and the Wearable Device includes: intelligent watches, intelligent bracelets, intelligent headphones, intelligent glasses, intelligent jewelry (intelligent bracelets, intelligent rings, intelligent necklaces, intelligent bracelets, intelligent footchains, etc.), intelligent bracelets, intelligent clothing, game machines, etc. Note that, the specific type of the terminal 11 is not limited in the embodiment of the present application. The network side device 12 may be a base station or a core network, wherein the base station may be referred to as a node B, an evolved node B, an access point, a base transceiver station (Base Transceiver Station, BTS), a radio base station, a radio transceiver, a basic service set (Basic Service Set, BSS), an extended service set (Extended Service Set, ESS), a node B, an evolved node B (eNB), a home node B, a home evolved node B, a WLAN access point, a WiFi node, a transmission and reception point (Transmitting Receiving Point, TRP), or some other suitable terminology in the field, and the base station is not limited to a specific technical vocabulary so long as the same technical effect is achieved, and it should be noted that in the embodiment of the present application, only the base station in the NR system is taken as an example, but the specific type of the base station is not limited.

Optionally, the scenario to which the embodiment of the present application is applicable includes, but is not limited to, a service with a survival time (survivinal time) requirement, and the like. For services with higher reliability requirements, the receiving end has the expected arrival time for the data packets. When the receiving end does not receive the data packet at the expected arrival time, the survival time is entered. If the receiving end has not successfully received any data packet within the alive time, the communication service will enter an unavailable state (unavailable state), so that a longer time is required for the recovery process of the normal communication service. In short, for this type of service, a loss of a plurality of consecutive packets cannot occur, otherwise the communication at the receiving end will enter an unavailable state.

Optionally, the data transmitting end (may be simply referred to as a transmitting end) in the embodiment of the present application may be a terminal or a network side device, and the corresponding data receiving end (may be simply referred to as a receiving end) is a network side device or a terminal.

Optionally, the data sending end and the receiving end in the embodiments of the present application may be both a terminal or a network side device. For example, in a side link scenario, both the data sending end and the receiving end are terminals.

The method, the device, the data transmitting end and the readable storage medium for exiting the survival time state provided by the embodiments of the present application are described in detail below with reference to the accompanying drawings through some embodiments and application scenarios thereof.

Referring to fig. 2, fig. 2 is a flowchart of a method for exiting a time-to-live state according to an embodiment of the present application, where the method is performed by a data transmitting end, and the data transmitting end may be selected as a terminal or a network side device. As shown in fig. 2, the method comprises the steps of:

step 21: the data transmitting terminal acquires the first information.

In this embodiment, the first information is used to assist in determining whether to exit the target bearer from the time-to-live state. The first information is related to a target bearer of the data transmitting end.

Alternatively, when the first information is acquired, the first information may be acquired by a radio resource control (Radio Resource Control, RRC) entity of the data transmitting end, or the first information may be acquired by a medium access control (Medium Access Control, MAC) entity of the data transmitting end, which is not limited.

Step 22: based on the first information, the target bearer of the data transmitting end exits the survival time state.

In some embodiments, the traffic corresponding to the target bearer has a time-to-live requirement. Illustratively, the time-to-live requirement is that two packets cannot be continuously lost, and then the target bearer can be put into the time-to-live state in the event of a packet loss. In the state of the active time, the data transmitting end can adopt a transmission strategy with higher reliability to transmit the service data corresponding to the target bearing.

Alternatively, the data transmitting end may exit the survival time state from its target bearer based on the first information after acquiring the first information. In some embodiments, the target bearer is located at a packet data convergence protocol (Packet Data Convergence Protocol, PDCP) entity, and the PDCP entity exits the time-to-live state based on the obtained first information. In other embodiments, the target bearer may correspond to another entity, and the data sending end may also exit the target bearer from the time-to-live state based on the obtained first information through the other entity corresponding to the target bearer.

In some embodiments, the target bearer may have PDCP duplication functionality. The network may configure the target bearer with at least two transmission paths, which may correspond to a single network node or to a plurality of different network nodes. The PDCP layer of the target bearer can transmit one copy of data per transmission path when transmitting the data, so as to improve data transmission reliability.

In the method for exiting the survival time state according to the embodiment of the present application, the data transmitting end may acquire first information, and based on the first information, exit the survival time state from the target bearer. Therefore, the data transmitting end can exit the survival time state, so that resource expenditure caused by using a high-reliability transmission strategy under the condition of keeping the time survival state for a long time is avoided, and resource consumption is reduced.

Optionally, when the RRC entity of the data transmitting end obtains the first information, the target bearer of the data transmitting end exits the survival time state when at least one of the following is satisfied:

1) The first information includes first indication information, where the first indication information is used to indicate that the target bearer exits the time-to-live state. For example, the first indication information may be a one-bit indication. In one case, when the network side device issues the first indication information to the data sending end (such as the terminal UE), the data sending end determines that the target bearer needs to exit from the survival time state. In another case, when the first indication information is set to a preset value, the data sending end determines that the target bearer needs to exit from the survival time state.

2) The first information includes second instruction information for instructing to deactivate a data copy function of the target bearer. For example, when the protocol convention or the network configuration uses the data replication function of at least two transmission paths when the target bearer enters the survival time state, when the network side device indicates that the data replication function of the target bearer is deactivated, the data transmitting end (such as the terminal UE) considers that the target bearer needs to exit the survival time state.

3) The first information comprises first configuration information, and the transmission path state corresponding to the target bearer configured by the first configuration information meets a first preset condition. The first configuration information is used for reconfiguring the transmission path state corresponding to the target bearer.

Optionally, the first preset condition may include at least one of:

(1) any one transmission path in the active state is deactivated, that is, any one transmission path in the active state of the first configuration information configuration target bearer is deactivated. For example, the currently activated transmission paths of the target bearer include leg1, leg2 and leg3, and if the first configuration information configures the transmission paths leg1 and leg2 of the target bearer to be in an activated state and leg3 to be in a deactivated state, the data transmitting end considers that the target bearer needs to exit from the survival time state.

Based on the above (1), the above first preset condition may also be: any N transmission paths in an active state are deactivated, N is an integer greater than 1, and N can be set by protocol convention or according to actual requirements.

(2) The number of the transmission paths in the activated state is less than or equal to a first preset value, that is, the number of the transmission paths in the activated state, carried by the first configuration information configuration target, is less than or equal to the first preset value. For example, the number of transmission paths in an activated state of the target bearer configured by the first configuration information is 2, which is smaller than a preset value 3. In this case, the target bearer of the data transmitting end needs to exit the time-to-live state.

(3) The number of the transmission paths in the deactivated state is greater than or equal to a second preset value, that is, the number of the transmission paths in the deactivated state, carried by the first configuration information configuration target, is greater than or equal to the second preset value. For example, the number of transmission paths in the deactivated state of the target bearer configured by the first configuration information is 2, which is greater than a preset value 1. In this case, the target bearer of the data transmitting end needs to exit the time-to-live state.

It can be appreciated that the first preset value and the second preset value may be set by a protocol or according to actual requirements, which is not limited.

Optionally, when the MAC entity of the data transmitting end obtains the first information, the target bearer of the data transmitting end exits the survival time state when at least one of the following is satisfied:

1) The first information includes a first media access control element (Medium Access Control Control Element, MAC CE) for indicating that the target bearer exits the time-to-live state. As one example, the first MAC CE may be identified by a dedicated logical channel identification (Logical Channel Identify, LCID) identifying that the first MAC CE exits the MAC CE for a time-to-live state. Illustratively, an LCID value reserved by the current protocol is taken and dedicated to indicating the first MAC CE. When the MAC entity of the data transmitting end acquires a first MAC CE, the target bearing is judged to need to exit the survival time state based on the first MAC CE. In one case, the first MAC CE may be zero bits, that is, only MAC header (header). In this case, when the data transmitting end obtains the first MAC CE on a dedicated resource (e.g., a dedicated Dynamic Grant (DG) resource) of the target bearer, the target bearer is considered to need to exit the time-to-live state. In another case, the first MAC CE may carry a bearer identifier of the target bearer, and when the first MAC CE is acquired, the data sending end may consider that the bearer identifier carried by the first MAC CE corresponds to the target bearer and needs to exit the survival time state. In yet another case, the first MAC CE indicates a bit corresponding to the target bearer, and when the bit is set to a preset value (e.g., set to 1), the corresponding target bearer is considered to be out of the time-to-live state.

2) The first information includes a second MAC CE for indicating to deactivate a data copy function of the target bearer. For example, when the second MAC CE obtained by the data transmitting end indicates to deactivate the data copy function of the target bearer, the data transmitting end considers that the target bearer needs to exit the surviving time state, and the second MAC CE activates/deactivates the MAC CE (duplication activation/deactivation MAC CE) for example, for the conventional data copy function.

3) The first information includes a third MAC CE, where the third MAC CE is configured to indicate that a transmission path state corresponding to the target bearer meets a second preset condition. Illustratively, the third MAC CE is configured to instruct to deactivate or deactivate a corresponding transmission path of the target bearer.

Optionally, the second preset condition may include at least one of:

(1) any one of the transmission paths currently in the active state is deactivated, i.e. the third MAC CE indicates that any one of the transmission paths currently in the active state of the target bearer is deactivated. For example, the currently active transmission paths of the target bearer include leg1, leg2 and leg3, and if the third MAC CE indicates that the transmission paths leg1 and leg2 of the target bearer are in an active state and leg3 is in a deactivated state, the data transmitting end considers that the target bearer needs to exit from the survival time state.

Based on the above (1), the above second preset condition may also be: any N transmission paths in an active state are deactivated, N is an integer greater than 1, and N can be set by protocol convention or according to actual requirements.

(2) The number of transmission paths in the active state is less than or equal to a third preset value, i.e. the third MAC CE indicates that the number of transmission paths in the active state of the target bearer is less than or equal to the third preset value. For example, the number of transmission paths of the target bearer indicated by the third MAC CE in the active state is 2, which is smaller than the preset value 3. In this case, the target bearer of the data transmitting end needs to exit the time-to-live state.

(3) The number of transmission paths in the deactivated state is greater than or equal to a fourth preset value, that is, the third MAC CE indicates that the number of transmission paths in the deactivated state of the target bearer is greater than or equal to the fourth preset value. For example, the number of transmission paths of the target bearer indicated by the third MAC CE in the deactivated state is 2, which is greater than a preset value of 1. In this case, the target bearer of the data transmitting end needs to exit the time-to-live state.

It can be appreciated that the third preset value and the fourth preset value may be set by a protocol or according to actual requirements, which is not limited.

(4) Only one transmission path is in an active state, i.e. the third MAC CE indicates that only one transmission path of the target bearer is in an active state. In this case, the data sender considers that the target bearer needs to exit the time-to-live state.

In the embodiment of the present application, in the case that the target bearer exits from the surviving state, the data sending end may perform an operation related to exiting from the surviving state on the target bearer. For the exit time-to-live state related operations, the exit time-to-live state may be performed while the target bearer is exiting the time-to-live state, or may be performed after the target bearer exits the time-to-live state.

Optionally, the first protocol entity of the data sending end may perform the operation related to exiting the survival time state on the target bearer.

It should be noted that, before the first protocol entity at the data sending end performs the operation related to exiting the survival time state on the target bearer, the first protocol entity may receive third indication information from the second protocol entity at the data sending end, where the third indication information indicates that the target bearer exits the survival time state, and the second protocol entity is a protocol entity that obtains the first information. Illustratively, the second protocol entity may be an RRC entity, and the first protocol entity may be a MAC entity, or a PDCP entity. In addition, the second protocol entity may provide third indication information to the plurality of first protocol entities. For example, the target bearer corresponds to two MAC entities, and when the RRC entity at the data transmitting end obtains the first information, third indication information may be provided to the two MAC entities, and the two MAC entities perform the operation related to exiting the survival time state on the target bearer. As another example, the second protocol entity may be a MAC entity, and the first protocol entity may be an RRC entity, or a PDCP entity. For example, the target bearer corresponds to two MAC entities, and when any MAC entity obtains the first information, third indication information is provided to the PDCP entity corresponding to the target bearer, and the PDCP entity performs an operation related to exiting the time-to-live state on the target bearer. As another example, the first protocol entity and the second protocol entity may both be MAC entities.

Optionally, the operation related to exiting the survival time state, which is performed by the data sending end on the target bearer, may include at least one of the following:

(1) And resetting a first counter, wherein the first counter is used for monitoring the data transmission faults of the transmission path of the target bearing. Illustratively, a first protocol entity (e.g., a MAC entity) at the data transmitting end maintains a first counter for each transmission path, and monitors the transmission status of the corresponding transmission path based on the first counter. If the count value of the first counter reaches a preset value, the corresponding transmission path is considered to have transmission faults. And under the condition that the target bearing exits from the survival time state, the first protocol entity of the data transmitting end executes a reset operation on the first counter corresponding to each transmission path. As one example, in the event of exiting the time-to-live operation, the first protocol entity (e.g., MAC entity) initiates the provision of transmission failure indication information to the third protocol entity (e.g., MAC entity). For example, after exiting the time-to-live, if the first counter value reaches a preset value, the first protocol entity (e.g., MAC entity) provides the transmission failure indication information to the third protocol entity (e.g., MAC entity).

(2) And resetting a second counter, wherein the second counter is used for monitoring the data transmission faults of the cell group where the transmission path of the target bearing is located. For example, a first protocol entity (such as a MAC entity) at the data transmitting end maintains a second counter for each cell group where the transmission path of the target bearer is located, and monitors the transmission state of the corresponding cell group based on the second counter. If the count value of the second counter reaches the preset value, the corresponding cell group is considered to have transmission faults. And under the condition that the corresponding target bearing exits from the survival time state, the first protocol entity of the data sending end executes a reset operation on the second counter corresponding to the cell group. As one example, in the event of exiting the time-to-live operation, the first protocol entity (e.g., MAC entity) initiates the provision of transmission failure indication information to the third protocol entity (e.g., MAC entity). For example, after exiting the time-to-live, if the first counter value reaches a preset value, the first protocol entity (e.g., MAC entity) provides the transmission failure indication information to the third protocol entity (e.g., MAC entity).

(3) And resetting a third counter, wherein the third counter is used for monitoring the data transmission fault of the target bearing. For example, the first protocol entity (such as PDCP entity) at the data transmitting end maintains a third counter for the target bearer, and monitors the transmission status of the corresponding target bearer based on the third counter. If the count value of the third counter reaches the preset value, the target bearing is considered to have transmission faults. And under the condition that the target bearer exits from the survival time state, the first protocol entity of the data sending end executes a reset operation on a third counter corresponding to the target bearer.

In this embodiment of the present application, in the case that the target bearer exits the survival time state, the data sending end may transmit data corresponding to the target bearer based on second configuration information, where the second configuration information is used to indicate a transmission path available after the target bearer exits the survival time state. For transmitting the data corresponding to the target bearer based on the second configuration information, the data may be executed while the target bearer exits the time-to-live state, or may be executed after the target bearer exits the time-to-live state.

Optionally, the second configuration information may satisfy at least one of:

1) The second configuration information is preconfigured. Illustratively, an exit survival time field is introduced that indicates the transmission paths available after the exit survival time of the target bearer. For example, the exit survival time domain is configured to the data sending end in advance through an RRC message, and when the target bearer is judged to need to exit the survival time based on the acquired first information, the data of the target bearer is transmitted by using a transmission path available after the exit survival time configured in advance.

2) The second configuration information is carried by the first information. As an example, the first MAC CE included in the first information may additionally carry transmission path indication information for indicating a transmission path available after the target bearer exits the time-to-live state. As another example, when the third MAC CE included in the first information indicates to exit the time-to-live state, the data of the target bearer is transmitted using the activated transmission path indicated by the third MAC CE.

3) The second configuration information is protocol agreed. For example, in the case where it is determined that the target bearer exits the surviving state, the protocol commits to always transmit data of the target bearer using the primary transmission path. As an example, in case that the data copy function of the target bearer is instructed to be deactivated through the RRC message or the second MAC CE, the data of the target bearer is always transmitted using the primary transmission path after the target bearer exits the time-to-live state.

It should be noted that, in the method for exiting the survival time state provided in the embodiment of the present application, the execution body may be a device for exiting the survival time state, or a control module in the device for exiting the survival time state for executing the method for exiting the survival time state. In the embodiment of the present application, a method for executing a device exiting a survival time state by using the device exiting a survival time state as an example is described.
