Description

Technical Field

[0001] This application belongs to the field of communication technology, specifically relating to a service processing method, apparatus, network node, and readable storage medium. Background Technology

[0002] For services with higher reliability requirements, it is necessary to ensure that there are no consecutive N data transmission failures; otherwise, the receiving end's communication service will enter an unavailable state, where N is an integer greater than 1. To avoid the receiving end's communication service becoming unavailable, if there are M consecutive data transmission failures, where M is a positive integer less than N, the service's radio bearer will enter a liveness state. In this state, the data sender can use a high-reliability transmission strategy to transmit data, hoping that subsequent data packets will be transmitted successfully.

[0003] However, in existing dual connectivity (DC) scenarios, network nodes cannot know the data transmission status, and therefore cannot know that the service's radio bearer has entered the liveness state. Consequently, they cannot provide the resources needed to transmit data in the liveness state in a timely manner, resulting in low reliability of service transmission. Summary of the Invention

[0038] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0039] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such terms can be used interchangeably where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first" and "second" are generally of the same class, not limited in number; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0040] It is worth noting that the technologies described in this application are not limited to Long Term Evolution (LTE) / LTE-Advanced (LTE-A) systems, but can also be used in other wireless communication systems, such as Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal Frequency Division Multiple Access (OFDMA), Single-carrier Frequency-Division Multiple Access (SC-FDMA), and other systems. The terms "system" and "network" in this application are often used interchangeably, and the described technologies can be used with the systems and radio technologies mentioned above, as well as with other systems and radio technologies. The following description describes New Radio (NR) systems for illustrative purposes, and the term NR is used in most of the following description; however, these technologies can also be applied to applications other than NR systems, such as 6th generation (6G) radio systems. th Generation 6G communication system.

[0041] Figure 1 This is a schematic diagram of a wireless communication system provided in an embodiment of this application. The wireless communication system may include a first network node 11 and a second network node 12.

[0042] In this embodiment, the first network node 11 is the network node where the anchor of the target bearer is located; that is, the anchor of the target bearer is located at the first network node 11. The target bearer is the bearer corresponding to a target service with a lifespan requirement, and the target bearer can be a split bearer. The second network node 12 is not the network node where the anchor of the target bearer is located. Therefore, in this embodiment, the first network node 11 can also be called the anchor network node or the anchor network node, and the second network node 12 can also be called the non-anchor network node or the non-anchor network node.

[0043] The target bearer's anchor point is located at the first network node 11, which can be specifically manifested as follows: the Packet Data Convergence Protocol (PDCP) corresponding to the target bearer is located at the first network node 11.

[0044] In a specific implementation, in one approach, the first network node 11 can be the master network node (MN), and the second network node 12 can be the secondary network node (SN). In this implementation, the anchor point carried by the target is located at MN. In another implementation, the first network node 11 can be the master network SN, and the second network node 12 can be MN. In this implementation, the anchor point carried by the target is located at SN. In practical applications, whether the anchor point carried by the target is located at MN or SN can be decided by MN; that is, MN decides the location of the anchor point carried by the target.

[0045] For ease of understanding, the following describes some aspects of the embodiments of this application:

[0046] I. Survival Time (ST).

[0047] For services with higher reliability requirements, the receiving end has an expected arrival time for data packets. If the receiving end does not receive a data packet within the expected arrival time, it enters a liveness timeout period. If the receiving end still fails to successfully receive any data packet within the liveness timeout period, its communication service will enter an unavailable state, requiring a longer recovery time. Simply put, for this type of service, multiple consecutive data packet losses are unacceptable; otherwise, the receiving end's communication will become unavailable. This type of service can be described as a service with a liveness time requirement.

[0048] II. PDCP duplication function.

[0049] In New Radio (NR), a network can configure at least two transmission paths for a radio bearer. These paths can correspond to a single network node (e.g., carrier aggregation (CA) duplication) or multiple different network nodes (DC duplication). The radio bearer's PDCP layer can transmit a copy of the data along each transmission path to improve data transmission reliability. The network side can control the status of the radio bearer's data duplication function (e.g., activating / deactivating the data duplication function) via Media Access Control (MAC) control element (CE) signaling; and / or, control the status of the radio bearer's transmission paths (e.g., activating / deactivating the transmission paths). When a radio bearer's transmission path corresponds to multiple network nodes, any network node can issue the aforementioned MAC CE. There is no negotiation between network nodes when issuing the aforementioned MAC CE.

[0050] The embodiments of this application will be described in detail below with reference to the accompanying drawings and through some examples and application scenarios.

[0051] See Figure 2 , Figure 2 This is one of the flowcharts of the business processing method provided in the embodiments of this application. Figure 2 The business processing method can be executed by the first network node, i.e., the anchor network node. For example... Figure 2 As shown, the business processing method may include the following steps:

[0052] Step 201: The first network node performs the first operation. The first network node is the network node where the anchor point of the target bearer is located. The target bearer is the bearer corresponding to the target service with a life-or-live requirement.

[0053] It should be noted that the network node where the anchor point of the target bearer is located can be understood as the network node where the PDCP entity of the target bearer is located. For example, if the PDCP of the target bearer is located at the main network node MN, then MN is the anchor point of the target bearer.

[0054] The target bearer is the radio bearer required to carry the service data with time-to-live requirements. The target bearer can be a radio bearer that has already been decided upon or established, or a radio bearer that a network node is waiting to establish for transmitting the target service data. Further details will not be provided hereafter.

[0055] In this application embodiment, the first operation may include at least one of the following:

[0056] 1) Send first configuration information to the second network node, the first configuration information being used to assist the second network node in performing radio resource management operations related to the target bearer, the second network node being not the network node where the anchor point of the target bearer is located;

[0057] 2) Perform management operations related to the lifespan status of the target.

[0058] In 1), the first configuration information can be used to indicate the survival-related information of the target bearer, such as the target bearer having a survival time requirement, or the survival time requirement information of the service corresponding to the target bearer. Optionally, the survival time requirement information can be reflected by duration (e.g., the maximum time that can be tolerated for data transmission failure), or it can be reflected by the number of data packets (e.g., the number of data packets that can be tolerated for loss).

[0059] In this way, after receiving the first configuration information, the second network node can perform radio resource management operations related to the target bearer based on the first configuration information. For example, it can: not issue control signaling to activate the transmission path of the target bearer after the target bearer enters the liveness time state, thereby ensuring the data transmission reliability of the target bearer in the liveness time state; or, provide radio resources for the transmission path that needs to be activated after the target bearer enters the liveness time state, or, provide radio resources for the transmission path that needs to be activated after the data transmission failure of the transmission path of the target bearer located at the second network node. This can increase the available transmission paths of the target bearer located at the second network node, and enable the target service to have higher reliability data transmission after the target bearer enters the liveness time state, thereby improving the reliability of the target service transmission.

[0060] The first configuration information can also be used to explicitly or implicitly instruct the second network node to prohibit the use of the following control signaling: control signaling for controlling the data replication function of the target bearer, such as PDCP duplication activation / deactivation MAC CE; and / or control signaling for controlling the state of the transmission path of the target bearer, such as RLC duplication activation / deactivation MAC CE. In this way, after receiving the first configuration information, the second network node can avoid erroneously using the above control instructions, which could deactivate the transmission path of the target bearer and prevent the target bearer from achieving higher reliability data transmission, thereby improving the reliability of the target service transmission.

[0061] In step 2), the management operation can be used to indicate whether the target bearer of the first network-side device is in a liveness state. In this way, the second network node can promptly learn whether the target bearer has entered the liveness state and perform radio resource management operations related to the target bearer. This ensures that the target service has higher reliability data transmission after the target bearer enters the liveness state, thereby improving the reliability of the target service transmission.

[0062] In the service processing method of this embodiment, the anchor network node can perform a first operation to assist the non-anchor network node in performing radio resource management operations related to the target bearer, thereby ensuring that the target service has more reliable data transmission after the target bearer enters the liveness time state, and improving the reliability of the target service transmission.

[0063] For 1)

[0064] Optionally, the first configuration information may include at least one of the following:

[0065] The first indication information is used to indicate at least one of the following: the target bearer has a life-time requirement; the target bearer's corresponding target life-time requirement information;

[0066] The second indication information is used to indicate at least one of the following: the anchor point of the target bearer is located at the first network node; the second network node prohibits the use of the first control signaling, which is used to control the state of the transmission path corresponding to the target bearer; the second network node prohibits the use of the second control signaling, which is used to control the state of the data replication function of the target bearer.

[0067] When the first indication information indicates that the target bearer has a time-to-live requirement, the first indication information can use a single bit to indicate whether the bearer has a time-to-live requirement. For example: when the bit value is 0, it can indicate that the bearer does not have a time-to-live requirement; when the bit value is 1, it can indicate that the bearer has a time-to-live requirement.

[0068] The target lifetime requirement information can be expressed as duration or number of data packets. Duration can be understood as the maximum time during which data transmission failure can be tolerated, and the number of data packets can be understood as the number of data packets that can be lost tolerable loss. The target lifetime requirement information can be configured by network-side devices, provided by the core network, or agreed upon by a protocol; for example, the target lifetime requirement information can be 2 milliseconds (ms).

[0069] When the second indication information indicates that the anchor point of the target bearer is located at the first network node, the second network node can be implicitly instructed to prohibit the use of the first control signaling and / or the second control signaling. For example, the protocol stipulates that for wireless bearers carrying service data with time-to-live requirements, the non-anchor network node of the aforementioned wireless bearer is prohibited from using the aforementioned first control signaling and / or the second control signaling. The prohibition of the second network node from using the first control signaling and / or the second control signaling can be understood as: the non-anchor network node will not issue the first control signaling and / or the second control signaling. The first control signaling can also be called the transmission path activation / deactivation control signaling corresponding to the target bearer, and the second control signaling can also be called the data replication function activation / deactivation control signaling of the target bearer. The first control signaling and the second control signaling can be MAC CE signaling, but are not limited to this.

[0070] Optionally, sending the first configuration information to the second network node includes:

[0071] The first configuration information is sent to the second network node through the target process;

[0072] The target process is any one of the following: the SN addition process; the SN modification process initiated by the MN; or the SN modification process initiated by the SN.

[0073] In this optional embodiment, the first network node can send the first configuration information during the target process. The first network node can reduce signaling overhead by reusing messages from the target process to send the first configuration information. Of course, in other embodiments, the first network node can send the first configuration information at other times, depending on actual needs. This application does not limit this.

[0074] Optionally, when the first network node is MN and the second network node is SN, the first configuration information satisfies at least one of the following:

[0075] When the target process is an SN addition process, the first configuration information is carried through an SN addition request message in the target process. For example, the MN initiates the SN addition process, informing the Data Radio Bearer (DRB1) (carrying service data with time-to-live requirements) that its anchor point is on the MN, and that some transmission paths of the DRB1 require the use of SN resources. During this process, the MN can additionally indicate that the DRB1 has time-to-live requirements. In this case, the SN can provide radio resource management for the transmission paths of the DRB1 located on the SN, for example, actively refraining from issuing control signaling to activate the target bearer's transmission paths. The MN can also additionally instruct a second network node to prohibit the use of the first control signaling and / or the second control signaling; based on this instruction, the SN will not issue control signaling to activate the target bearer's transmission paths.

[0076] In the case where the target process is an SN modification process initiated by the MN, the first configuration information is carried through an SN modification request message in the target process. For example, when a new service with a time-to-live requirement arrives, the MN initiates an SN modification process, informing DRB1 (carrying service data with a time-to-live requirement) that its anchor point is on the MN, and that DRB1 has some transmission paths that require SN resources. During this process, the MN can additionally indicate that DRB1 has a time-to-live requirement. In this case, the SN can provide radio resource management for the transmission paths of DRB1 located on the SN, for example, actively refraining from issuing control signaling to activate the target bearer's transmission paths. The MN can also additionally instruct a second network node to prohibit the use of the first control signaling and / or the second control signaling; based on this instruction, the SN will not issue control signaling to activate the target bearer's transmission paths.

[0077] In the case where the target process is an SN modification process initiated by the SN, the first configuration information is carried by the SN modification request ACK message in the target process.

[0078] Optionally, when the first network node is SN and the second network node is MN, the first configuration information satisfies at least one of the following:

[0079] When the target process is an SN addition process, the first configuration information is carried through an SN addition request ACK message in the target process; the ACK message can also be called a response message. For example, when a new service with a time-to-live requirement arrives, the MN initiates an SN addition process, informing the SN that the anchor point of the radio bearer corresponding to the target service is on the SN via an SNaddition request message. The SN will establish a radio bearer DRB1 for the target service. In the SN addition response message, the SN can inform the MN that the DRB1 will use MN resources. During this process, the SN can additionally indicate that the DRB1 has a time-to-live requirement. In this case, the MN can provide radio resource management for the transmission path of the DRB1 located on the MN, for example, actively refraining from issuing control signaling to activate the transmission path of the target bearer. The SN can also additionally instruct a second network node to prohibit the use of the first control signaling and / or the second control signaling; then, based on this instruction, the MN will not issue control signaling to activate the transmission path of the target bearer.

[0080] Additionally, it should be noted that if the SN is the anchor point of the target bearer, and the MN knows that the target bearer is used to carry target service data with lifespan requirements, the SN may not provide the first configuration information to the MN.

[0081] In the case where the target process is an SN modification process initiated by the MN, the first configuration information is carried through the SN modification request ACK message in the target process. For example, when a new service with a time-to-live requirement arrives, the MN initiates an SN modification process, informing the SN via an SN modification request message that the anchor point of DRB1 (carrying service data with a time-to-live requirement) is on the SN. The SN will establish a radio bearer DRB1 for the target service. In the SN add response message, the SN can inform the MN that the DRB1 will use MN resources. During this process, the SN can additionally indicate that the DRB1 has a time-to-live requirement. In this case, the MN can provide radio resource management for the transmission path of the DRB1 located on the MN, for example, actively refraining from issuing control signaling to activate the transmission path of the target bearer. The SN can also additionally instruct a second network node to prohibit the use of the first control signaling and / or the second control signaling; then, based on this instruction, the MN will not issue control signaling to activate the transmission path of the target bearer.

[0082] In the case where the target process is an SN modification process initiated by the SN, the first configuration information is carried through an SN modification required message in the target process. For example, the SN initiates the SN modification process. In the SN modification required message, DRB1 is reconfigured from an SCG bearer to a split bearer SN. The SN informs the MN that DRB1 will use MN resources. During this process, the SN may additionally indicate that DRB1 has a time-to-live requirement. In this case, the MN may provide radio resource management for the transmission path of DRB1 located on the MN, for example, actively refraining from issuing control signaling to activate the transmission path of the target bearer. The SN may also additionally instruct a second network node to prohibit the use of the first control signaling and / or the second control signaling; based on this instruction, the MN will not issue control signaling to activate the transmission path of the target bearer.

[0083] For 2)

[0084] Optionally, the management operations related to the lifetime status of the target bearer include one of the following:

[0085] Send a sixth indication message to the second network node, the sixth indication message being used to indicate that the target bearer enters the liveness time state;

[0086] A seventh indication message is sent to the second network node, the seventh indication message being used to indicate the target bearer's exit liveness time status.

[0087] The first network node is the network node where the anchor point of the target is located. Therefore, the first network node can promptly determine the current state of the target.

[0088] When the first network node determines that the target node has entered the liveness time state, the first network node can send a sixth indication message to the second network node to enable the second network node to perform radio resource management operations related to the target bearer, such as: prohibiting the use of the first control signaling and / or the second control signaling; providing radio resources for the transmission path that needs to be activated after the target bearer enters the liveness time state, thereby ensuring that the target service has higher reliability data transmission after the target bearer enters the liveness time state, and thus improving the reliability of the target service transmission.

[0089] When the first network node determines that the target node has exited the liveness time state, the first network node can send a seventh indication message to the second network node so that the second network node can perform radio resource management operations related to the target bearer, such as releasing radio resources for the transmission path that needs to be activated after the target bearer enters the liveness time state, so that the released radio resources can be allocated to other users, thereby improving resource utilization.

[0090] In one implementation of this application, the first network node can autonomously perform management operations related to the lifetime status of the target bearer. In another implementation, optionally, performing the management operations related to the lifetime status of the target bearer includes:

[0091] Receive the second configuration information sent by the second network node;

[0092] Based on the second configuration information, perform management operations related to the lifetime status of the target bearer.

[0093] In this optional implementation, the first network node performs management operations related to the lifetime status of the target bearer based on the configuration information sent by the second network node, thereby improving the effectiveness of the management operations.

[0094] In a specific implementation, the second configuration information can be any configuration information that can trigger the first network node to perform management operations related to the lifespan status of the target bearer.

[0095] Optionally, the second configuration information may include at least one of the following:

[0096] The fourth indication information is used to instruct the first network node to send indication information to the second network node to indicate that the target bearer has entered the liveness time state;

[0097] The fifth instruction information is used to instruct the first network node to send an instruction information to the second network node to indicate the exit time-of-life status of the target bearer.

[0098] In this optional implementation, when the first network-side device receives the fourth indication information, it can send the sixth indication information to the second network node if it determines that the target node has entered the liveness time state.

[0099] Upon receiving the fifth indication information, the first network-side device may send the seventh indication information to the second network node if it determines that the target node has exited the liveness time state.

[0100] See Figure 3 , Figure 3 This is the second flowchart of the business processing method provided in the embodiments of this application. Figure 3 The business processing method is executed by the second network node. For example... Figure 3 As shown, the business processing method may include the following steps:

[0101] Step 301: The second network node performs radio resource management operations related to the target bearer. The second network node is not the network node where the anchor point of the target bearer is located. The target bearer is the bearer corresponding to the target service with a time-to-live requirement.

[0102] In specific implementation, the second network node can perform radio resource management operations related to the target bearer when it determines that the target bearer has a time-to-live requirement. In practice, the second network node can learn that the target bearer has a time-to-live requirement from the anchor network node or from the core network, depending on the actual situation. This application embodiment does not limit this. For example, assuming the second network node is MN, MN obtains the service information of the target service from the core network, knows that the target bearer has a time-to-live requirement, and then performs radio resource management operations related to the target bearer.

[0103] In this embodiment, the wireless resource management operation may include prohibiting the second network node from using control signaling for controlling the data replication function and / or transmission path status of the target bearer. This avoids the second network node incorrectly using the control instructions, which could restrict the available transmission path of the target bearer and prevent the target bearer from achieving more reliable data transmission, thereby improving the reliability of the target service transmission.

[0104] The radio resource management operation may also include providing radio resources to a first target transmission path where the target bearer is located on a second network node. This first target transmission path can be a transmission path that needs to be activated additionally when the target bearer enters its time-to-live state, or a transmission path that needs to be activated additionally when the active transmission path of the target bearer fails to transmit data. This increases the available transmission paths for the target bearer, ensuring that the target service can achieve higher reliability data transmission after the target bearer enters its time-to-live state, thereby improving the reliability of the target service transmission.

[0105] The wireless resource management operation may also include releasing wireless resources on a second target transmission path of the target bearer located on the second network node. This second target transmission path can be a transmission path that needs to be deactivated when the target bearer exits its liveness state, or a transmission path that needs to be deactivated when data transmission is successfully completed on an active transmission path of the target bearer. In this way, the second network node can allocate the released wireless resources to other users, thereby improving resource utilization.

[0106] In this embodiment, the service processing method involves non-anchor network nodes performing wireless resource management operations related to the target bearer, which can improve the reliability of service transmission and / or improve resource utilization.

[0107] Optionally, the execution of radio resource management operations related to the target bearer may include at least one of the following:

[0108] a) The use of the first control signaling is prohibited. The first control signaling is used to control the state of the transmission path corresponding to the target bearer.

[0109] b) The use of the second control signaling, which is used to control the data replication function of the target bearer, is prohibited;

[0110] c) If a first condition is met, provide radio resources for the first transmission path of the target bearer located in the first network node, wherein the first condition includes at least one of the following: a data transmission failure occurs in the second transmission path of the target bearer located in the first network node; or a sixth indication is received, wherein the sixth indication is an indication for the target bearer to enter a liveness time state.

[0111] d) If the second condition is met, release radio resources for the third transmission path of the target bearer located in the first network node, wherein the second condition includes at least one of the following: the data transmission of the fourth transmission path of the target bearer located in the first network node is normal; or a seventh indication message is received, wherein the seventh indication message is an indication message for the target bearer to exit the liveness time state.

[0112] In a) and b), prohibiting the use of control signaling can be manifested in any of the following ways: prohibiting the sending of control signaling; stopping the sending of control signaling; suspending the sending of control signaling; or not sending control signaling. The specific method can be determined according to actual needs, and this application embodiment does not limit it.

[0113] In c), optionally, the first transmission path can be a transmission path that needs to be activated when the target bearer enters the liveness state; or, the first transmission path can be a transmission path that needs to be activated when the second transmission path experiences a data transmission failure.

[0114] The form of the first transmission path can be related to the form of the first condition. Optionally, when the first condition is that the second transmission path of the target bearer located at the first network node experiences a data transmission failure, since the second network node may not be able to know in time whether the target bearer has entered the liveness time state, the first transmission path can be the transmission path that needs to be activated when the second transmission path experiences a data transmission failure; when the first condition is that the sixth indication information is received, the second network node can know that the target bearer has entered the liveness time state, therefore, the first transmission path can be the transmission path that needs to be activated when the target bearer has entered the liveness time state.

[0115] The first transmission path may include at least one transmission path where the target bearer is located at the first network node. The first transmission path may be configured by the network side or agreed upon by the protocol, and this application embodiment does not limit this.

[0116] A data transmission failure in the second transmission path can manifest as P consecutive data transmission failures, where P is an integer less than N. The second transmission path may include: part or all of the transmission paths of the target bearer located at the second network node and in an active state before providing radio resources to the first transmission path of the target bearer located at the first network node.

[0117] Optionally, providing radio resources for the first transmission path may include at least one of the following:

[0118] The allocation of reserved resources corresponding to the first transmission path to other users is stopped. For example, the second network node reserves wireless resources for the first transmission path. From the terminal's perspective, the reserved wireless resources are inactive until the target bearer enters its liveness state. Once the target bearer enters its liveness state, the terminal automatically considers the reserved wireless bearer to be active. From the network's perspective, before the target bearer enters its liveness state or before a transmission failure occurs on the transmission path of the target bearer located at the second network node, the second network node considers the reserved resources of the first transmission path unnecessary for the corresponding terminal and can therefore allocate the reserved resources to other users. When the target bearer enters its liveness state or a transmission failure occurs on the transmission path of the target bearer located at the second network node, the second network node considers the reserved resources of the first transmission path to be used by the corresponding terminal and therefore stops allocating the reserved resources corresponding to the first transmission path to other users.

[0119] A third control signaling is sent to activate the reserved resources corresponding to the first transmission path. In the event that the target bearer enters a live state or a transmission path of the target bearer located at the second network node experiences a transmission failure, the second network node can allocate reserved resources, such as type 2 cell group (CG) resources, for the first transmission path by issuing the third control signaling.

[0120] In this way, by stopping the allocation of reserved resources corresponding to the first transmission path to other users and activating the reserved resources corresponding to the first transmission path, the resources required for data transmission on the first transmission path can be guaranteed, thereby enabling the first transmission path to be used for data transmission, increasing the available transmission paths for the target bearer, achieving more reliable data transmission for the target bearer, and improving the reliability of service transmission.

[0121] c) This can include the following scenarios:

[0122] Scenario 1: In the event of a data transmission failure in the second transmission path of the target carrier located at the first network node, wireless resources are provided for the first transmission path, which is the transmission path that needs to be activated in the event of a data transmission failure in the second transmission path.

[0123] In Scenario 1, after the second network node learns that a data transmission failure has occurred in the second transmission path, it can autonomously provide wireless resources for the first transmission path without signaling instructions, thereby reducing signaling overhead.

[0124] Scenario 2: Upon receiving the sixth instruction information, provide radio resources for the first transmission path, which is the transmission path that needs to be activated when the target bearer enters the liveness time state.

[0125] In scenario 2, the second network node provides radio resources to the first transmission path based on the indication sent by the first network node that the target bearer has entered the liveness time state. This can avoid providing radio resources to the first transmission path before the target bearer enters the liveness time state, thereby improving resource utilization.

[0126] In d), optionally, the third transmission path can be a transmission path that needs to be deactivated when the target bearer exits the liveness time state; or, the third transmission path can be a transmission path that needs to be deactivated when the fourth transmission path data transmission is normal.

[0127] The manifestation of the third transmission path can be related to the manifestation of the second condition. Optionally, if the second condition is that the target bearer is located at the first network node and the fourth transmission path data transmission is normal, it indicates that the data transmission is very likely to succeed. Therefore, the third transmission path can be the transmission path that needs to be deactivated when the fourth transmission path data transmission is normal. If the second condition is that the seventh indication information is received, the second network node can know that the target bearer has exited the liveness time state. Therefore, the third transmission path can be the transmission path that needs to be deactivated when the target bearer has exited the liveness time state.

[0128] The third transmission path may include at least one transmission path where the target bearer is located at the first network node. The third transmission path may be configured by the network side or agreed upon by the protocol, and this application embodiment does not limit this.

[0129] The fourth transmission path transmits data normally, which can be manifested by the fourth transmission path successfully transmitting data at least once. The second transmission path may include: some or all of the transmission paths of the target bearer located at the second network node and in an active state before the release of radio resources for the third transmission path of the target bearer located at the first network node.

[0130] Optionally, releasing radio resources for the third transmission path includes at least one of the following:

[0131] Allocate the reserved resources corresponding to the third transmission path to other users;

[0132] Send a fourth control signaling message, which is used to deactivate the reserved resources corresponding to the third transmission path.

[0133] In this way, by allocating the reserved resources corresponding to the third transmission path to other users, resource utilization can be improved; by deactivating the reserved resources corresponding to the third transmission path, data transmission through the third transmission path can be stopped, thereby saving resource costs.

[0134] d) may include the following scenarios:

[0135] Scenario 1: When the target bearer is located at the first network node and the fourth transmission path is transmitting data normally, release wireless resources for the third transmission path. The third transmission path is the transmission path that needs to be deactivated when the fourth transmission path is transmitting data normally.

[0136] In Scenario 1, after the second network node learns that the data transmission on the fourth transmission path is normal, it can release the radio resources of the third transmission path on its own without signaling instructions, thereby reducing signaling overhead.

[0137] Scenario 2: Upon receiving the seventh instruction information, release radio resources for the third transmission path, which is the transmission path that needs to be deactivated when the target bearer exits the liveness time state.

[0138] In Scenario 2, the second network node releases the radio resources of the third transmission path based on the indication sent by the first network node that the target bearer has exited its liveness time state. This avoids releasing the radio resources of the first transmission path before the target bearer exits its liveness time state, thereby improving the reliability of service transmission.

[0139] In this embodiment of the application, the second network node can autonomously perform radio resource management operations related to the target bearer. For example, assuming the second network node is MN, MN obtains the service information of the target service from the core network and knows that the target bearer has a lifespan requirement. In this case, the second network node can autonomously perform radio resource management operations related to the target bearer.

[0140] Of course, in other implementations, the second network node may also learn that the target bearer has a time-to-live requirement based on the configuration or indication of the anchor network node of the target bearer, and then perform radio resource management operations related to the target bearer, as detailed below.

[0141] Optionally, the second network node performs radio resource management operations related to the target bearer, including:

[0142] The second network node obtains first configuration information, which is used to assist the second network node in performing radio resource management operations related to the target bearer.

[0143] The second network node performs radio resource management operations related to the target bearer based on the first configuration information.

[0144] It should be noted that the second network node may obtain the first configuration information by receiving it, obtaining it from a protocol, or learning it through implementation means. The specific method can be determined according to the actual situation, and this application embodiment does not limit it.

[0145] Optionally, the first configuration information includes at least one of the following:

[0146] The first indication information is used to indicate at least one of the following: the target bearer has a life-time requirement; the target bearer's corresponding target life-time requirement information;

[0147] The second indication information is used to indicate at least one of the following: the anchor point of the target bearer is located at a first network node, and the first network node is the network node where the anchor point of the target bearer is located; the second network node prohibits the use of the first control signaling, which is used to control the state of the transmission path corresponding to the target bearer; the second network node prohibits the use of the second control signaling, which is used to control the state of the data replication function of the target bearer.

[0148] Optionally, the second network node performs radio resource management operations related to the target bearer, including:

[0149] The second network node receives the target indication information;

[0150] The second network node performs radio resource management operations related to the target bearer based on the target indication information;

[0151] The target indication information includes at least one of the following:

[0152] The sixth indication information is used to indicate that the target bearer enters the survival time state;

[0153] The seventh indication information is used to indicate the target bearer's exit survival time status.

[0154] In specific implementation, the sending end of the target indication information can send it autonomously or based on an indication from a second network node. For the latter, optionally, the method further includes:

[0155] The second network node sends second configuration information to the first network node, the second configuration information including at least one of the following:

[0156] The fourth indication information is used to instruct the first network node to send indication information to the second network node to indicate that the target bearer has entered the liveness time state;

[0157] The fifth instruction information is used to instruct the first network node to send an instruction information to the second network node to indicate the exit time-of-life status of the target bearer.

[0158] Optionally, the second network node sends second configuration information to the first network node, including:

[0159] The second network node sends the second configuration information to the first network node through the target process;

[0160] The target process is any one of the following: the SN addition process; the SN modification process initiated by the MN; or the SN modification process initiated by the SN.

[0161] That is, the second network node can send the second configuration information during the target process. By reusing the messages in the target process to send the second configuration information, the signaling overhead can be reduced.

[0162] Optionally, when the first network node is MN and the second network node is SN, the second configuration information satisfies at least one of the following:

[0163] In the case where the target process is an SN addition process, the second configuration information is carried by the SN addition request message in the target process. For example, the MN initiates the SN addition process, informing the MN via an SN addition request message that the anchor point of the radio bearer DRB1 corresponding to the target service with liveness requirements is on the MN. During this process, the MN additionally instructs a fourth instruction, which instructs the SN to send an instruction to the MN indicating that the target bearer is entering the liveness state. It can be understood that in this case, it is equivalent to the MN configuring the SN to provide the MN with the instruction information indicating that the target bearer is entering the liveness state. The MN additionally instructs a fifth instruction, which instructs the SN to send an instruction to the MN indicating that the target bearer is exiting the liveness state. It can be understood that in this case, it is equivalent to the MN configuring the SN to provide the MN with the instruction information indicating that the target bearer is exiting the liveness state.

[0164] When the target process is an SN addition process, the second configuration information is carried by the SN addition request response message in the target process. For example, the MN initiates the SN addition process, informing the MN via an SN addition request message that the anchor point of the radio bearer DRB1 corresponding to the target service with time-to-live requirement is on the MN. In the SN addition request response message, the SN additionally indicates a fourth indication, which instructs the SN to send indication information to the MN to indicate that the target bearer enters the time-to-live state. It can be understood that in this case, it is equivalent to the SN informing the MN that it will provide the MN with indication information for the target bearer to enter the time-to-live state. The SN additionally indicates a fifth indication, which instructs the SN to send indication information to the MN to indicate that the target bearer exits the time-to-live state. It can be understood that in this case, it is equivalent to the SN informing the MN that its SN will provide the MN with indication information for the target bearer to exit the time-to-live state.

[0165] In the case where the target process is an SN modification process initiated by the MN, the second configuration information is carried through the SN modification request message in the target process. For example, the MN initiates the SN modification process, informing the MN via the SN modification request message that the anchor point of the radio bearer DRB1 corresponding to the target service with liveness requirements is on the MN. During this process, the MN additionally instructs a fourth instruction message, which instructs the SN to send an instruction message to the MN indicating that the target bearer is entering the liveness state. It can be understood that in this case, the MN configures the SN to provide the MN with an instruction message indicating that the target bearer is entering the liveness state. The MN additionally instructs a fifth instruction message, which instructs the SN to send an instruction message to the MN indicating that the target bearer is exiting the liveness state. It can be understood that in this case, the MN configures the SN to provide the MN with an instruction message indicating that the target bearer is exiting the liveness state.

[0166] In the case where the target process is an SN addition process, the second configuration information is carried through the SN addition request response message in the target process. For example, the MN initiates the SN addition process, informing the MN via an SN modification request message that the anchor point of the radio bearer DRB1 corresponding to the target service with liveness requirements is on the MN. In the SN modification request response message, the SN additionally indicates a fourth indication, which instructs the SN to send indication information to the MN indicating that the target bearer enters the liveness state. It can be understood that in this case, it is equivalent to the SN informing the MN that it will provide the MN with indication information indicating that the target bearer has entered the liveness state. The SN additionally indicates a fifth indication, which instructs the SN to send indication information to the MN indicating that the target bearer has exited the liveness state. It can be understood that in this case, it is equivalent to the SN informing the MN that its SN will provide the MN with indication information indicating that the target bearer has exited the liveness state.

[0167] In the case where the target process is an SN modification process initiated by the SN, the second configuration information is carried through the SN modification request response message in the target process. For example, the SN initiates an SN modification process, reconfiguring radio bearer DRB1 from an SCG bearer to a split bearer via an SNmodification required message. During this process, the MN additionally indicates a fourth indication in the SN modification require response message, instructing the SN to send an indication to the MN indicating that the target bearer enters a liveness state. The SN additionally indicates a fifth indication, instructing the SN to send an indication to the MN indicating that the target bearer exits the liveness state.

[0168] In the case where the target process is an SN modification process initiated by the SN, the second configuration information is carried through an SN modification required message in the target process. For example, the SN initiates an SN modification process, reconfiguring radio bearer DRB1 from an SCG bearer to a split bearer via an SN modification required message. During this process, the SN additionally instructs a fourth instruction to send an instruction to the MN indicating that the target bearer is entering a liveness state. It can be understood that in this case, it is equivalent to the SN informing the MN that it will provide the MN with an instruction indicating that the target bearer is entering a liveness state. The SN additionally instructs a fifth instruction to send an instruction to the MN indicating that the target bearer is exiting a liveness state. It can be understood that in this case, it is equivalent to the SN informing the MN that it will provide the MN with an instruction indicating that the target bearer is exiting a liveness state.

[0169] Optionally, when the first network node is SN and the second network node is MN, the second configuration information satisfies at least one of the following:

[0170] When the target process is an SN addition process, the second configuration information is carried through the SN addition request response message in the target process. For example, the MN initiates the SN addition process, informing the MN via an SN addition request message that the anchor point of the radio bearer DRB1 corresponding to the target service with liveness requirements is on the MN. In the SN addition request response message, the SN additionally indicates a fourth indication, which instructs the MN to send an indication to the SN to indicate that the target bearer enters the liveness state. The SN additionally indicates a fifth indication, which instructs the MN to send an indication to the SN to indicate that the target bearer exits the liveness state.

[0171] When the target process is an SN addition process, the second configuration information is carried through the SN addition request message in the target process. For example, the MN initiates the SN addition process, informing the MN via an SN addition request message that the anchor point of the radio bearer DRB1 corresponding to the target service with liveness requirements is on the MN. In the SN addition request message, the MN additionally indicates a fourth indication, which instructs the MN to send indication information to the SN to indicate that the target bearer enters the liveness state. In this case, it is equivalent to the MN informing the SN that it will provide the SN with indication information for the target bearer to enter the liveness state. The MN additionally indicates a fifth indication, which instructs the MN to send indication information to the SN to indicate that the target bearer exits the liveness state. It can be understood that in this case, it is equivalent to the MN informing the SN that it will provide the SN with indication information for the target bearer to exit the liveness state.

[0172] When the target process is an SN modification process initiated by the MN, the second configuration information is carried through the SN modification request response message in the target process. For example, the MN initiates an SN addition process, informing the MN via an SNmodification request message that the anchor point of the radio bearer DRB1 corresponding to the target service with liveness requirements is on the MN. In the SN modification request response message, the SN additionally indicates a fourth indication, which instructs the MN to send an indication to the SN to indicate that the target bearer enters the liveness state. The SN additionally indicates a fifth indication, which instructs the MN to send an indication to the SN to indicate that the target bearer exits the liveness state.

[0173] When the target process is an SN modification process initiated by the MN, the second configuration information is carried through the SN modification request response message in the target process. For example, the MN initiates an SN addition process, informing the MN via an SNmodification request message that the anchor point of the radio bearer DRB1 corresponding to the target service with liveness requirements is on the MN. In the SN modification request message, the MN additionally indicates a fourth indication, which instructs the MN to send an indication to the SN to indicate that the target bearer enters the liveness state. In this case, it is equivalent to the MN informing the SN that it will provide the SN with indication information for the target bearer to enter the liveness state. The MN additionally indicates a fifth indication, which instructs the MN to send an indication to the SN to indicate that the target bearer exits the liveness state. It can be understood that in this case, it is equivalent to the MN informing the SN that it will provide the SN with indication information for the target bearer to exit the liveness state.

[0174] In the case where the target process is an SN modification process initiated by the SN, the second configuration information is carried by the SN modification request message in the target process.

[0175] It should be noted that this embodiment is as a comparison with... Figure 2 The method embodiment corresponds to the embodiment of the second network node; therefore, please refer to the embodiment of the second network node. Figure 2 The relevant descriptions in the method embodiments can achieve the same beneficial effects. To avoid repetition, they will not be repeated here.

[0176] It should be noted that the various optional implementation methods described in the embodiments of this application can be combined with each other or implemented individually, and the embodiments of this application do not limit this.

[0177] For ease of understanding, the following example is provided:

[0178] Business processing methods may include the following steps:

[0179] Step 1: The first target network node provides the second target network node with target configuration information related to the target bearer, wherein the target bearer is the radio bearer required to transmit target service data, and the target service has a life-or-live requirement.

[0180] In practice, the first target network node can be the primary network node and the second target network node can be the secondary network node; or the first target network node can be the secondary network node and the second target network node can be the primary network node. For example, the SN node provides target configuration information to the MN node.

[0181] The target configuration information includes any one of the following:

[0182] When the target anchor point is located at the first target network node, the target configuration information may include one or more of the following:

[0183] The first indication information is used to indicate the lifetime requirement of the target bearer. For example: the PDCP of the target bearer is on the MN node, and the target bearer is a separate bearer. The MN provides the first indication information to the SN to inform the SN that the target bearer has a lifetime requirement. The first indication information can indicate the specific lifetime requirement corresponding to the target bearer, such as indicating that the lifetime requirement of the target bearer is 2ms. The first indication information can also be a one-bit indication information used to inform the second target network node that the target bearer has a lifetime requirement.

[0184] The second indication information is used to instruct the second target network node to prohibit the use of at least one of the following: transmission path activation / deactivation control signaling; data replication function activation / deactivation control signaling. For example, the PDCP of the target bearer is at the MN node. The MN provides the second indication information to the SN node to inform the SN to prohibit the use of transmission path activation / deactivation control signaling for the target bearer. Since the second target network node cannot promptly know whether the target bearer has entered the time-to-live state, it may mistakenly use MAC CE signaling to deactivate the transmission path, causing data packets sent by the target bearer in the time-to-live state to fail to transmit successfully, thus failing to meet the time-to-live requirement. By providing the second indication information to the second target network node, the above situation can be avoided, thereby improving the reliability of service transmission. The second indication information can be explicit, for example, the first target network node instructs the second target network node to prohibit the use of transmission path activation / deactivation control signaling for the target bearer through explicit domain information. The second indication information can also be implicit. For example, the first target network node can implicitly indicate to the second target network node that the non-anchor network node (i.e., the second target network node) must prohibit the use of transmission path activation / deactivation control signaling for the target bearer by indicating the anchor point of the target bearer.

[0185] It is understood that, in this case, the target configuration information can be understood as the aforementioned first configuration information.

[0186] When the target anchor point is located at the second target network node, the target configuration information may include one or more of the following:

[0187] The fourth indication information is used to instruct the second target network node to provide the first target network node with indication information indicating that the target bearer has entered the liveness time state. It should be further noted that the first target network node provides the indication information indicating that the target bearer has entered the liveness time state when the second target network node does so.

[0188] The fifth indication information is used to instruct the second target network node to provide the first target network node with indication information regarding the target bearer's exit from its lifetime status. It should be further noted that the first target network node provides the indication information regarding the target bearer's exit from its lifetime status when the second target network node does so.

[0189] It is understood that, in this case, the target configuration information can be understood as the aforementioned second configuration information.

[0190] Optionally, when the first target network node is the primary network node and the second target network node is the secondary network node, the provision of the target configuration information from the first target network node to the second target network node can occur in any of the following processes:

[0191] The process of adding a second target network node. For example: the first target network node is MN, and the second target network node is SN. During the addition of SN, MN decides to place the anchor point of the target bearer at MN and configures the target bearer as a separate bearer. The target configuration information can then be provided to SN in the SN addition request.

[0192] The process of modifying the second target network node initiated by the first target network node. For example: the first target network node is MN, and the second target network node is SN. If MN decides to configure the Master Cell Group (MCG) bearer as a separate bearer, then MN can provide the target configuration information to SN in the SN modification request message; or, when processing target services with time-to-live requirements, MN decides to place the anchor point of the target bearer for that target service on MN, and MN provides the target configuration information to SN.

[0193] The modification process of the second target network node initiated by the second target network node. For example: When processing a target service with a time-to-live requirement, the MN decides to place the anchor point of the target bearer of the target service in the SN. The MN can provide the target configuration information to the SN in the SNmodification request.

[0194] Optionally, when the first target network node is a secondary network node and the second target network node is a primary network node, the provision of the first indication information from the first target network node to the second target network node can occur in any of the following processes:

[0195] The process of adding the first target network node. For example: the first target network node is SN, and the second target network node is MN. MN decides to place the anchor point of the target bearer at SN, and SN decides to configure the target bearer as a separate bearer. Then, in the SN addition request ACK message, SN provides the target configuration information to MN.

[0196] The first target network node initiates the first target network node modification process. For example: the first target network node is SN, and the second target network node is MN. SN decides to configure the SCG bearer as a separate bearer; therefore, in the SN modification request, SN provides the target configuration information to MN.

[0197] The modification process of the first target network node initiated by the second target network node. For example: When processing a target service with a time-to-live requirement, the MN decides to place the anchor point of the target bearer of that target service on the SN. In the SNmodification request ACK, the SN provides the target configuration information to the MN.

[0198] Step 2: The anchor network node in the first and second target network nodes performs a liveness time status management operation. For example, if the target's anchor point is MN, then SN performs the liveness time status management operation based on the target configuration information.

[0199] In practice, anchor network nodes can perform liveness status management operations based on the target configuration information sent by non-anchor network nodes.

[0200] Optionally, the survival time status management operation may include any of the following:

[0201] Anchor network nodes send a sixth indication message to non-anchor network nodes. This sixth indication message indicates that the target bearer has entered a time-to-live state. For example, the first target network node is MN, and the target bearer's anchor point is MN. When MN determines that the target bearer has entered a time-to-live state, it sends the sixth indication message to the second target network node.

[0202] Anchor network nodes send a seventh indication message to non-anchor network nodes. This seventh indication message indicates that the target bearer has exited its time-to-live (TTL) state. For example, the first target network node is MN, and the target bearer's anchor point is MN. When MN determines that the target bearer has exited its TTL state, it sends the seventh indication message to the second target network node.

[0203] Step 3: The non-anchor network nodes in the first and second target network nodes perform wireless resource management operations.

[0204] In practice, non-anchor network nodes can perform wireless resource management operations based on the target configuration information sent by anchor network nodes.

[0205] Optionally, the wireless resource management includes one or more of the following;

[0206] Non-anchor network nodes are prohibited from using transmission path activation / deactivation control signaling for the target bearer. For example, the second target network node is SN, and the anchor point of the target bearer is MN. SN is prohibited from using transmission path activation / deactivation control signaling for the target bearer.

[0207] Provide radio resources for the target transmission path carried by a target located at a non-anchor network node when any of the following conditions are met:

[0208] A data transmission failure occurs on any active transmission path located at a non-anchor network node. For example, if the number of transmission failures on any one of the one or more active transmission paths located at a non-anchor network node reaches a preset value, a data transmission failure is considered to have occurred.

[0209] All active transmission paths located at non-anchor network nodes experience data transmission failures. For example, a data transmission failure is considered to have occurred when the number of transmission failures on all active transmission paths located at non-anchor network nodes reaches a preset value.

[0210] The sixth instruction information is obtained from the anchor network node.

[0211] Optionally, the non-anchor network node provides radio resources for the target transmission path carried by the target located at the non-anchor network node, including any one of the following:

[0212] Stop allocating reserved resources corresponding to the target transmission path to other users. For example, a non-anchor network node reserves resources for the target transmission path and instructs that these resources be activated when the corresponding target bearer enters its time-to-live state. While the target bearer is not in its time-to-live state, the non-anchor network node can allocate the corresponding resources to other users; upon entering the time-to-live state, it stops allocating the corresponding resources to other users.

[0213] Send control information to activate the reserved resources corresponding to the target transmission path.

[0214] Release radio resources for the target transmission path carried by a target located at a non-anchor network node when any of the following conditions are met:

[0215] Data transmission failure is recovered when any active transmission path located on a non-anchor network node recovers. For example, if any one of the one or more active transmission paths on a non-anchor network node successfully transmits data or the number of successful transmissions reaches a preset value, the data transmission failure is considered recovered. The non-anchor network node can then reallocate the radio resources reserved for the target transmission path to other users.

[0216] The seventh instruction information is obtained from the anchor network node.

[0217] The target transmission path refers to the transmission path located on a non-anchor network node that needs to be activated when the target bearer enters the time-to-live state. The target transmission path can be configured on the network side, for example, the target bearer can be configured with legs 1 / 2 / 3 / 4, where legs 3 / 4 are located on the second target network node. Leg 3 is a transmission path already activated before entering the time-to-live state, and leg 4 is a transmission path configured on the network side that needs to be activated when entering the time-to-live state. The target transmission path can also be a protocol agreement; for example, if the protocol stipulates that all transmission paths of the target bearer are activated when entering the time-to-live state, then leg 4 would be the target transmission path.

[0218] The embodiments of this application can be applied to 5G and subsequent evolution communication systems.

[0219] Through the embodiments of this application, when a radio bearer enters a liveness state, the network side can guarantee the resources required for data transmission in that state, avoiding the situation where network nodes cannot provide reliable resources because they do not know whether the radio bearer has entered a liveness state.
