[0002] With the increasingly wide application of Internet technology, network application scenarios are different, such as enhanced mobile broadband scenarios, low-latency high-reliability scenarios, and low-power large-connection scenarios. 5G network services are also rapidly developing to meet customers' use requirements for wireless networks in various scenarios. Network providers can configure 5G wireless networks to provide services to clients, and different application scenarios have different configuration requirements for 5G wireless networks. A 5G wireless network is usually composed of multiple distributed 5G base stations and core network servers. The core network servers and the 5G base stations can communicate with each other. Clients can establish a network connection between any base station and the core network server to obtain 5G wireless communication services. Clients inevitably need to switch base stations during movement. For 5G base stations with small coverage, base station switching is more frequent. In traditional technical methods, since 5G base stations are independent of each other, the client needs to configure slice-related information and perform resource configuration during the base station switching process to establish a connection with each base station, which is a complex process, resulting in a long time consumption during base station switching, low switching efficiency, and easy communication interruption with the client, thereby affecting the communication continuity and the network use experience of the client during base station switching.

[0035] Please refer to Figure 1 and Figure 2 , Figure 1 Flowchart of the terminal continuous communication method based on 5G base station switching provided by the embodiments of the present application; Figure 2The application scenario schematic diagram of the terminal continuous communication method based on 5G base station switching provided by the embodiment of the present application; the terminal continuous communication method based on 5G base station switching is applied to a 5G communication service network 10, the 5G communication service network 10 is used for providing 5G communication services for clients, the 5G communication service network 10 comprises a core network server 101 and a plurality of base stations 102, the terminal continuous communication method based on 5G base station switching is executed through application software installed in the core network server 101 and each base station 102, the client 20 can establish a network connection with the core network server 101 through any base station 102 to realize wireless transmission of data information, the base station 102 and other base stations 102 adjacent thereto establish a network connection to realize transmission of data information; the core network server 101 is a core network end constructed by a telecom operator and used for providing 5G communication services for the client 20, the base station 102 is a communication base station used for providing wireless communication access, such as a fixed base station arranged at the top of a building or a vehicle-mounted mobile base station, and the client 20 is a terminal device used for use by a user and for wireless data transmission with the core network server 101, such as a notebook computer, a tablet computer, a mobile phone and other 5G terminal devices, or a smart watch, smart glasses and other wearable terminal devices. Figure 2 Only one client 20 accesses the 5G communication service network 10 and transmits information, in actual application, the 5G communication service network 10 can also simultaneously establish a communication connection with a plurality of clients 20 to realize transmission of data information. Figure 1 As shown in the figure, the method comprises steps S110-S150.

[0036] S110, the first base station connected with the client continuously monitors whether the client leaves a first park corresponding to the first base station and approaches other base stations.

[0037] The base station can be used to establish a communication connection with the client and provide communication services for the client. When the base station communicates information with the client, the base station can detect the signal strength of the accessed client. The first base station can determine whether the client is leaving the first park corresponding to the first base station by judging the signal strength change of the accessed client. Specifically, the base station communication has a certain effective coverage range. Generally, the area corresponding to the effective coverage range of the base station is the park of the base station. Generally, the park area of the 3G network base station is larger than that of the 4G network base station, and the park area of the 4G network base station is larger than that of the 5G network base station. The interval distance between the base station and the client is inversely proportional to the signal strength. The first base station can determine whether the signal strength value of the client changes from large to small and approaches the strength threshold value. The strength threshold value is the signal strength value corresponding to the edge of the effective coverage range of the first base station. If the signal strength value of the client continuously decreases and approaches the strength threshold value, it is determined that the client is leaving the first park corresponding to the first base station. The telecommunication operator usually sets multiple base stations to cover a large area. The base stations are spaced apart by a certain distance. When the client is leaving the first park, it will approach other base stations at the same time. The other base stations adjacent to the first base station are usually single-digit. The direction of the client leaving the first park can be monitored by the first base station, so as to determine another base station approached by the client when leaving the first park. The other base stations adjacent to the first base station can also continuously monitor the signal strength of the client accessing each base station. If a certain base station adjacent to the first base station monitors that the signal strength value of the client continuously increases and approaches the strength threshold value, it is determined that the client is entering the park corresponding to the current base station. At this time, the current base station can send the message of the client entering the park to the first base station.

[0038] In S120, if it is monitored that the client leaves the first park and enters the second park corresponding to the second base station, the first base station generates a handover request message corresponding to the client and sends it to the second base station.

[0039] If it is detected that the client leaves the first park and enters the second park corresponding to the second base station, the first base station can generate a handover request message corresponding to the client and send it to the second base station, and the handover request message is a request message for base station handover. Specifically, the client accesses the first base station using a dedicated slice and a dedicated DNN. During the process of establishing a connection between the client and the first base station, the first base station is configured with slice configuration information, base station software and hardware resource group information, and life cycle information corresponding to the client, the slice configuration information includes slice ID, DNN network information, etc. The DNN network in the 5G network is similar to the APN network in the 4G network. The DNN network is a network access technology. According to the DNN, the session is split and converged to different SMF (Session Management Function) / UPF (User Port Function), which realizes the client's access to network resources. The base station software and hardware resource group information is the resource information related to the client's business configured in the base station. The life cycle information is the cycle information of the network access service related to the client's business. The base station reserves the corresponding access resources for the client according to different life cycle information. If the life cycle information is exceeded, the base station can recycle the resources reserved for the client, that is, by judging whether the use time of the life cycle information is exceeded to release the unused idle resources. The slice configuration information, base station software and hardware resource group information, and life cycle information related to the client can be obtained from the base station, and the corresponding handover request information can be generated and sent to the second base station.

[0040] In an embodiment, as shown in FIG. 1 1, step S120 includes sub-steps S121, S122, S123 and S124. Figure 3

[0041] S121, obtaining the slice configuration information corresponding to the client from the slice information database pre-configured in the first base station;

[0042] The first base station is pre-configured with a slice information database for storing slice configuration information corresponding to each client accessing the first base station. The corresponding slice configuration information can be obtained from the slice database according to the corresponding identification information of the client. The slice configuration information includes slice ID and DNN network information. The slice ID is an identification code corresponding to the client, that is, the slice ID corresponds to the client one by one. For example, the slice ID can be IMSI (International Mobile Subscriber Identity). According to the slice ID, the client and the slice configuration information corresponding to the client can be uniquely identified.

[0043] ​S122, obtaining initial resource reservation information corresponding to the initial base station reserved resource allocated to the client by the first base station;

[0044] When the client accesses the first base station, the first base station needs to allocate an initial base station reserved resource to the client, and the initial base station reserved resource is a base station software and hardware resource allocated by the first base station according to the network service demand of the client, for example, the initial base station reserved resource includes an RB resource block (Resource Block, base station network resource scheduling is taken as a basic unit), a channel resource, etc. The initial resource reservation information corresponding to the initial base station reserved resource is obtained, such as the number of RB resource blocks, the communication frequency of channel resources, etc.

[0045] S123, obtaining service resource information corresponding to the service message from the client;

[0046] After the client establishes a network connection with the first base station, the client can transmit a service message to the core network service through the first base station, or receive a service message through the first base station, so as to realize the transmission and reception of the message, and then the historical service message corresponding to the client can be obtained from the first base station, and the corresponding service resource information can be obtained from the historical service message, the service resource information includes service priority, life cycle information, etc., the service priority is determined according to different types of service messages, the higher the service priority is, the higher the priority of the corresponding service message transmission is, and the service resource information is determined by the client based on the service message transmitted and received by the first base station.

[0047] S124, combining the slice configuration information, the initial resource reservation information and the service resource information to generate a corresponding handover request message and sending the handover request message to the second base station.

[0048] The obtained slice configuration information, initial resource reservation information and service resource information are combined to generate a corresponding handover request information, and the network communication connection between the base stations is established, so that the first base station can send the handover request message to the second base station through the established network communication connection. The base station identifier corresponding to the first base station can also be added in the handover request message.

[0049] S130, the second base station allocates a base station reserved resource according to the received handover request message and generates a handover notification message and sends the handover notification message to the core network server.

[0050] The second base station allocates corresponding base station reserved resources for the client according to the received handover request message, and generates a corresponding handover notification message according to the handover request message and the allocated base station reserved resources, and sends the handover notification message to the core network server. The handover notification message is a notification message sent to the core network server to enable the core network server to configure corresponding server resources, thereby completing the base station handover.

[0051] In an embodiment, as shown in FIG. 1, step S130 includes sub-steps S131, S132 and S133. Figure 4

[0052] S131, write the slice configuration information in the handover request message into the slice information database preset in the second base station;

[0053] Specifically, the slice configuration information in the handover request message can be obtained, and the slice configuration information is written into the slice information database preset in the second base station. The second base station also has a slice information database preset for storing the slice configuration information of each client accessing the second base station.

[0054] S132, allocate corresponding base station reserved resources according to the initial resource reservation information and service resource information in the handover request message;

[0055] According to the initial resource reservation information and service resource information in the handover request message, corresponding base station reserved resources are allocated. In a practical application process, there are multiple clients simultaneously accessing or switching to the second base station. Therefore, multiple handover request messages / access request messages need to be sorted according to the service priority of each client, and the request message with the highest priority is allocated first. The base station reserved resources, and the request message with lower priority is allocated later. Specifically, according to the number of RB resource blocks, the communication frequency of channel resources, etc. in the initial resource reservation information, the corresponding base station reserved resources are allocated for the client corresponding to the handover request message, and the corresponding life cycle is configured for the allocated base station reserved resources according to the life cycle information in the service resource information.

[0056] S133, combine the slice configuration information and the service resource information to generate a corresponding handover notification message and send the handover notification message to the core network server.

[0057] The slice configuration information and the service resource information are combined, and a corresponding handover notification message is generated and sent to the core network server.

[0058] S140, the core network server allocates core network reserved resources according to the received handover notification message and sends notification information of successful reservation to the first base station.

[0059] ​The core network server can receive the handover notification message from the second base station, and send the notification information of the successful reservation to the first base station after the core network reserved resources are allocated according to the handover notification message. The core network reserved resources are the reserved resources allocated by the core network server according to the demand of the client for the service message transmission.

[0060] In an embodiment, as shown in FIG. 1, step S140 includes sub-steps S141, S142 and S143. Figure 5

[0061] S141, write the slice configuration information in the handover notification message into the server slice information database of the core network server.

[0062] The server slice information database is pre-configured in the core network server, and is a database configured in the core network server for storing the slice configuration information of the accessed client.

[0063] S142, allocate the corresponding core network reserved resources according to the service resource information in the handover notification message.

[0064] The core network reserved resources are allocated to the client corresponding to the handover notification message according to the service resource information, and the core network reserved resources include the necessary core network software and hardware resource groups for the service message transmission. Specifically, when the number of clients accessing the core network server is large, the handover notification messages of the clients can be sorted according to the service priority in the service resource information, the corresponding core network reserved resources are allocated to the clients with high service priority, and the life cycle of the allocated core network reserved resources is configured according to the life cycle information in the service resource information. For example, the life cycle can be configured as 20 seconds, and if the client fails to establish a communication connection with the core network server within 20 seconds, the allocated core network reserved resources can be released.

[0065] S143, if the core network reserved resources are successfully allocated, send the notification information of the successful reservation to the first base station.

[0066] The handover notification message further includes the base station identifier corresponding to the first base station, and if the core network reserved resources are successfully allocated, the notification information of the successful reservation can be sent to the first base station according to the base station identifier. In actual use, the allocation deadline can be configured, for example, the allocation deadline is configured as 0.5 seconds, and if the core network server fails to successfully allocate the core network reserved resources within 0.5 seconds after receiving the handover notification message, the reservation fails, otherwise the reservation succeeds. If the reservation fails, the first base station can also send the notification information of the failed reservation to the first base station, and the first base station can also try to send the handover request message again after receiving the notification information of the failed reservation.

[0067] ​In an embodiment, as shown in Figure 6 Step S130 further includes step S1310.

[0068] S1310, the second base station acquires base station resource reservation information corresponding to the base station reserved resource and sends it to the first base station.

[0069] After the second base station completes sending the handover notification message, it can also acquire base station resource reservation information corresponding to the base station reserved resource, and send the base station resource reservation information to the first base station according to the base station identifier in the handover request message. The base station resource reservation information is the information corresponding to the base station reserved resource allocated by the second terminal for the client.

[0070] S150, the first base station sends corresponding communication handover information to the client according to the received notification message, so that the client accesses the base station reserved resource and the core network reserved resource according to the communication handover information to realize base station handover.

[0071] The first base station can receive the notification message sent by the core network server, and send the communication handover information to the client according to the notification message. After the client receives the communication handover information, it can access the base station reserved resource allocated by the second base station and the core network reserved resource allocated by the core network server according to the communication handover information, thereby completing the base station handover. Specifically, after the client receives the communication handover information, it can perform non-competitive random access on the base station reserved resource and the core network reserved resource, and access the base station reserved resource and the core network reserved resource to realize uplink synchronization with the target cell, thereby successfully completing the base station handover process. Since the base station reserved resource is pre-allocated on the second base station side, and the core network reserved resource is pre-allocated on the core network server side, the client can quickly access the core network server through the second base station based on the pre-allocated resources. In the process of switching from the first base station to the second base station, the client does not need to reconfigure the slice-related information and resource configuration, thereby greatly reducing the operation process of the client side during base station handover, greatly reducing the time required for the client to perform base station handover, and improving the network smoothness of the client during base station handover.

[0072] In an embodiment, as shown in Figure 7 Step S150 includes sub-steps S151 and S152.

[0073] S151, generate a handover command corresponding to the notification message.

[0074] A corresponding handover command can be generated according to the notification message. The handover command can be a program code, and the handover command can include program instructions for disconnecting the communication connection corresponding to the first base station and establishing a communication connection corresponding to the second base station.

[0075] S152, combine the handover command and the base station resource reservation information to generate corresponding communication handover information and send to the client.

[0076] In the specific process, the handover command and the base station resource reservation information can also be combined to generate communication handover information and send to the client. After the client receives the communication handover information, it can quickly establish a communication connection with the second base station based on the base station resource reservation information in the communication handover information.

[0077] In an embodiment, as shown in FIG. 1, step S150 is followed by step S160. Figure 8

[0078] S160, if the core network server monitors that the client successfully accesses the communication through the core network reserved resources, release the idle reserved resources corresponding to the first base station.

[0079] The core network server can detect the state of the network connection of the client in real time. If the core network server monitors that the client successfully accesses the communication through the core network reserved resources, it indicates that the client has successfully established a communication connection with the core network server through the second base station at this time. At this time, the reserved resources allocated by the core network server for the client to access the communication through the first base station are in an idle state. In order to avoid the idle state of the server resources, the idle reserved resources corresponding to the first base station in the core network server can be released. The idle reserved resources are the reserved resources allocated by the core network server for the client to access the communication through the first base station. The released idle reserved resources can be used when other clients access the communication.

[0080] ​In the method for terminal continuous communication based on 5G base station switching provided in the embodiment of the present application, the first base station connected with the client continuously monitors whether the client leaves the first park area corresponding to the first base station and approaches other base stations; if it is monitored that the client leaves the first park area and enters the second park area corresponding to the second base station, the first base station generates a corresponding switching request message and sends it to the second base station; the second base station allocates base station reserved resources according to the switching request message and generates a switching notification message and sends it to the core network server; the core network server allocates core network reserved resources according to the switching notification message and sends notification information of successful reservation to the first base station; and the first base station sends corresponding communication switching information to the client according to the notification message, so that the client accesses the base station reserved resources and the core network reserved resources to realize base station switching. Through the above method, whether the client is about to perform base station switching can be detected, and resources are reserved based on information interaction between base stations and between base stations and the core network server, so that the client can quickly realize base station switching through the reserved resources, the switching efficiency is improved, and the network fluency of the client during base station switching is greatly improved.

[0081] The embodiment of the present application also provides a terminal continuous communication system based on 5G base station switching, which can be configured in a 5G communication service network, the 5G communication service network comprising a core network server and a plurality of base stations, and the terminal continuous communication system based on 5G base station switching is used to execute any embodiment of the terminal continuous communication method based on 5G base station switching described above.

[0083] The monitoring unit 110 is used to continuously monitor whether the client leaves the first park area corresponding to the first base station and approaches other base stations.

[0084] The switching request message sending unit 120 is used to generate a switching request message corresponding to the client and send it to the second base station if it is monitored that the client leaves the first park area and enters the second park area corresponding to the second base station.
