Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a service processing method, access network equipment, core network equipment and apparatus. Background Art

[0002] 5G defines three major application scenarios, namely enhanced mobile broadband (eMBB), ultra-reliable low-latency communications (uRLLC) and massive machine type communications (mMTC). Services in each application scenario need to be allocated corresponding resources.

[0003] At present, the 5G network usually uses the pre-scheduling method to allocate resources, that is, to allocate subsequent resources in advance for use. For uRLLC services, since there are relatively few uRLLC services in the existing network, resources are usually not allocated for uRLLC services. Instead, after the uRLLC services arrive, the resources allocated to eMBB are preempted.

[0004] However, this service processing method will have an adverse impact on existing eMBB services. Summary of the invention

[0126] In order to make the purpose, technical solutions and advantages of this application clearer, the technical solutions in this application will be clearly and completely described below in conjunction with the drawings in this application. Obviously, the described embodiments are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0127] 5G defines three major application scenarios: eMBB, uRLLC, and mMTC. The uRLLC scenario requires ultra-low latency and a certain rate.

[0128] At present, the 5G network often uses the pre-scheduling method to allocate resources. That is, the subsequent resources are allocated in advance for different types of services. Since there are relatively few uRLLC services in the current network, operators usually do not allocate resources for uRLLC services in advance. Instead, for a small number of uRLLC services, they are mixed with eMBB in one network to seize wireless resources.

[0129] Specifically, when a uRLLC service appears, if all wireless resources have been allocated to the eMBB service at this time, the uRLLC service can only seize resources through the type B (type B) type of the physical downlink shared channel (PDSCH) and the physical uplink shared channel (PUSCH), and seize the resources that have been allocated to the eMBB service to transmit the uRLLC service.

[0130] The above-mentioned processing method for uRLLC services has two disadvantages. On the one hand, typeB occupies fewer time domain symbol resources, the rate that can be provided to users is not high, and it is not suitable for high-speed mobile scenarios; on the other hand, by preempting resources, the user's perception will be reduced for users who have been allocated the resources, affecting the user's service. There are two ways to handle the preempted user service. The first way is to notify the terminal that the resource has been preempted through additional signaling. The second way is not to inform the terminal that the resource has been preempted. The terminal reads the resource normally, but cannot interpret it correctly, so the terminal feedbacks negative acknowledgment (NACK) and requires the base station to retransmit. Both the first and second methods will affect user perception. The second method will increase the user's block error rate (BLER), causing the terminal and the base station to misjudge the network environment, which will have a negative impact on the subsequent modulation and coding strategy (MCS) and uplink power control adjustment.

[0131] If fixed resources are reserved for the uRLLC service, it will not affect the perception of other users' services and can also ensure the time, rate, and high-speed mobility requirements of the uRLLC service. However, reserving fixed resources may lead to resource waste and further increase the burden on cells with higher loads.

[0132] Based on this, the embodiment of the present application provides a service processing method, which can process the uRLLC service without affecting the perception of other users and can also reduce the waste of resources. The solution of the embodiment of the present application is introduced below with reference to the accompanying drawings.

[0133] Figure 1 A flowchart of a service processing method provided in an embodiment of the present application, the method is applied to an access network device, such as Figure 1 As shown, the method includes:

[0134] S11, when receiving a service request sent by a terminal, sending the service request to a core network device, the service request is used to request processing of a target service.

[0135] The terminal sends a service request to the access network device in the current serving cell to request the processing of the target service. After receiving the service request, the access network device sends the service request to the core network device.

[0136] S12, receive the initial context establishment request sent by the core network device, the initial context establishment request includes the single network slice selection assistance information (Single Network Slice Selection Assistance Information, S-NSSAI) of the target service, the initial context establishment request is used to request to establish the context of the terminal.

[0137] After receiving the service request sent by the access network device, the core network device first determines the service type of the target service. In the embodiment of the present application, the service type of the target service is one of the eMBB service, uRLLC service, and mMTC service.

[0138] In a possible implementation manner, the service request includes an access point name (APN) of the terminal, and the core network device determines the service type of the target service according to the APN of the terminal.

[0139] After determining the service type of the target service, the core network device sends the S-NSSAI of the target service to the access network device according to the service type of the target service. The S-NSSAI is used to indicate the service type of the target service.

[0140] S-NSSAI is used to identify network slices. In order to identify end-to-end network slices, each network slice is uniquely identified by S-NSSAI. When a terminal opens an account, it will sign up for one or more S-NSSAIs on the Unified Data Management (UDM). When the terminal accesses the network, it carries these S-NSSAIs and can access the corresponding network slice.

[0141] Figure 2 The schematic diagram of the structure of S-NSSAI provided in the embodiment of the present application is as follows: Figure 2 As shown in Figure 1, S-NSSAI mainly consists of two parts, namely Slice / Service Type (SST) and Slice Differentiator (SD). SST refers to the expected network slice behavior in terms of functions and services, with a size of 8 bits; SD is used to supplement the optional information of SST and is used to distinguish multiple network slices in the same SST, with a size of 24 bits.

[0142] The size of SST is 8 bits, and the value is 0-255, where different SST values ​​correspond to different service types. The following table 1 illustrates some SST values ​​and corresponding service types:

[0143] Table 1

[0144]

[0145]

[0146] As shown in Table 1, some SST values ​​and corresponding service types are illustrated, where an SST value of 1 indicates that the corresponding service type is eMBB service, an SST value of 2 indicates that the corresponding service type is uRLLC service, an SST value of 3 indicates that the corresponding service type is mobile Internet of Things (MIoT) service, and an SST value of 4 indicates that the corresponding service type is vehicle to X (V2X) service.

[0147] Therefore, in one implementation, the core network device can determine the value of the target SST based on the correspondence between different SST values ​​and each service type, as well as the service type of the target service. Then, the S-NSSAI is sent to the access network device, and the S-NSSAI includes the target SST, and the service type of the target service is indicated by the value of the target SST. For example, when the service type of the target service is uRLLC service, the value of the target SST is determined to be 2, and when the service type of the target service is eMBB, the value of the target SST is determined to be 1, and so on.

[0148] S13, determining the service type of the target service according to the S-NSSAI.

[0149] After receiving the initial context establishment request sent by the core network device, the access network device obtains the S-NSSAI from the initial context establishment request. Since the core network device indicates the service type of the target service through the S-NSSAI, the access network device can determine the service type of the target service based on the S-NSSAI.

[0150] In one implementation, the access network device obtains the value of the target SST included in the S-NSSAI, and determines the service type of the target service based on the correspondence between different values ​​of the SST and each service type, as well as the value of the target SST. For example, based on the correspondence in the example of Table 1, if the value of the target SST is 2, the service type of the target service is determined to be the uRLLC service; if the value of the target SST is 3, the service type of the target service is determined to be the MIoT, and so on.

[0151] S14: When the service type is uRLLC service, the reserved resources of the target service are determined according to the context of the terminal and S-NSSAI, and the reserved resources are used for the terminal to process the target service.

[0152] When it is determined that the service type of the target service is a uRLLC service, for the uRLLC service, the access network device determines reserved resources of the target service according to the context of the terminal and S-NSSAI, for the terminal to process the target service.

[0153] Figure 3 A flowchart of determining reserved resources for a target service provided in an embodiment of the present application, such as Figure 3 As shown, including:

[0154] S31, obtaining the current predicted moving trajectory and moving speed of the terminal.

[0155] In order to make the determined reserved resources also applicable to high-speed movement scenarios, in an embodiment of the present application, based on the current service cell of the terminal, the trajectory of the terminal can be predicted to predict the cell to which the terminal may move, thereby reserving corresponding resources for the target service in the cell to which the terminal is to move.

[0156] Specifically, the access network device can obtain the terminal's current predicted moving trajectory and moving speed. For the predicted moving trajectory, the access network device can first obtain the moving trajectory of the terminal in the current service cell based on the positioning technology, and predict the trajectory of the terminal based on the moving trajectory of the terminal in the current service cell, thereby obtaining the predicted moving trajectory. Among them, the positioning technology may include, for example, round-trip time (RTT) positioning technology, time difference of arrival (TDOA) positioning technology, angle of arrival (AOA) positioning technology, angle of departure (AOD) positioning technology, etc., which is not limited in the embodiments of the present application. For the moving speed, the access network device can determine the moving speed of the terminal according to the distance of the moving trajectory of the terminal in the current service cell and the moving time after obtaining the moving trajectory of the terminal in the current service cell based on the positioning technology.

[0157] S32: Determine at least one candidate cell to be accessed by the terminal according to the predicted moving trajectory.

[0158] After the access network device determines the predicted moving trajectory of the terminal, the access network device determines the coverage range of each of the multiple cells, and then determines at least one candidate cell from the multiple cells based on the coverage ranges of the multiple cells and the predicted moving trajectory of the terminal, wherein the at least one candidate cell is a cell whose coverage range includes the predicted moving trajectory.

[0159] In an embodiment of the present application, the coverage of a cell includes a predicted mobile trajectory, which means that the coverage of the cell includes part or all of the predicted mobile trajectory. As long as the predicted mobile trajectory passes through the coverage of the cell, it can be determined that the coverage of the cell includes the predicted mobile trajectory. Specifically, after determining the respective coverage of multiple cells, the access network device determines the cells on the predicted mobile trajectory as candidate cells. Since the coverage of the candidate cell includes the predicted mobile trajectory, and the predicted mobile trajectory is predicted based on the historical mobile trajectory of the terminal, the candidate cell is a cell that the terminal is more likely to randomly access next.

[0160] S33, determining the reserved resources for the target service according to the inter-station distance between the current serving cell and each candidate cell, the context of the terminal, the S-NSSAI and the moving speed.

[0161] After at least one candidate cell is determined, reserved resources for the target service need to be allocated to each candidate cell.

[0162] Since the cell where the terminal is currently located is not a candidate cell but a current serving cell, and the terminal may move to the coverage of the candidate cell during movement, in order to reserve resources for the terminal's target service in advance, it is necessary to estimate in advance when the terminal will move to the candidate cell.

[0163] First, for each candidate cell, the access network device determines the time required for the terminal to move from the current service cell to the candidate cell based on the predicted moving trajectory according to the station spacing between the current service cell and the candidate cell, and the moving speed of the terminal, and determines the predicted time when the terminal accesses the candidate cell according to the time required for the terminal to move from the current service cell to the candidate cell based on the predicted moving trajectory.

[0164] The inter-station distance between the current service cell and the candidate cell reflects the distance from the current service cell to the candidate cell. Combined with the terminal's moving speed, the time required for the terminal to move from the current service cell to the candidate cell based on the predicted moving trajectory can be determined, and then the predicted time for the terminal to access the candidate cell can be estimated.

[0165] After determining the predicted time, the access network device determines the target period for allocating resources to the target service in the candidate cell according to the predicted time, and the target period is the period including the predicted time. For example, the target period may include 3 minutes before the predicted time to 2 minutes after the predicted time, or other possible periods.

[0166] After the target period is determined, the reserved resources allocated by the candidate cell for the target service during the target period can be determined according to the context of the terminal and S-NSSAI. The reserved resources allocated by the candidate cell for the target service are only valid during the target period.

[0167] The context of the terminal can be used for the terminal to switch from the current serving cell to the candidate cell, and the context of the terminal indicates the resource size required for the target service. The resource size required for the target service can be determined based on the context of the terminal. The type of resources required for the target service can be determined based on the S-NSSAI. According to the resource size and resource type required for the target service, the reserved resources allocated by the candidate cell for the target service during the target period can be determined. Specifically, according to the determined target period, the packet data convergence protocol (PDCP) protocol data unit (PDU) to be transmitted by the current serving cell to the candidate cell, the context of the terminal and the S-NSSAI, the strategy to be executed for the PDU session of the terminal is determined, thereby determining the reserved time-frequency domain resources.

[0168] If the terminal switches from the current serving cell to the corresponding candidate cell within the target period, the terminal may use the reserved resources allocated by the candidate cell for the target service within the target period to process the target service.

[0169] Since the movement of the terminal is disorderly, in some cases, the terminal does not switch from the current serving cell to the corresponding candidate cell within the target period. At this time, the reserved resources of the candidate cell need to be released in time. Specifically. For any candidate cell, during the target period when the candidate cell allocates resources for the target service, the access network device determines whether the terminal accesses the candidate cell. If it is determined that the terminal does not access the candidate cell within the target period, the reserved resources allocated by the candidate cell for the target service within the target period are released to further avoid waste of resources.

[0170] The service processing method provided by the embodiment of the present application is that when the access network device receives the service request sent by the terminal, the access network device sends the service request to the core network device, and the service request is used to request the processing of the target service; the core network device sends the initial context establishment request to the access network device, which is used to request the establishment of the context of the terminal. The initial context establishment request includes the S-NSSAI of the target service. The access network device determines the service type of the target service according to the S-NSSAI. When the service type is uRLLC service, the access network device determines the reserved resources of the target service according to the context and S-NSSAI of the terminal, which are used for the terminal to process the target service. The solution of the present application does not need to seize the resources of the eMBB service for the uRLLC service, but reserves resources for the uRLLC service, which will not affect the eMBB service. Moreover, since resources are reserved for the uRLLC service on demand according to the context and S-NSSAI of the terminal, the waste of resources is also reduced to a certain extent. At the same time, candidate cells can be determined based on the predicted mobile trajectory of the terminal, and reserved resources can be allocated to the target service in the candidate cells. This is suitable for scenarios where the terminal moves at high speed, and can provide uRLLC services with resources that meet service needs, thereby reducing the delay of uRLLC service switching.
