Description

Background Art

[0002] In the 5G era, the investment, number of base stations and difficulty of building stations are far beyond the 4G network, and the high maintenance costs of base stations and asset depreciation have to be borne in the later stage. Under the influence of factors such as the continuous promotion of speed increase and fee reduction, the investment cost of 4G has not been fully recovered, and the profit model of 5G is not yet clear, in order to ensure the construction of 5G mobile communication network, co-construction and sharing among operators may be the only way to "reduce costs and increase efficiency".

[0003] Load balancing in a co-built and shared network is a wireless LAN system that provides access services to mobile terminals of multiple operators by multiple access points. Each access point member manages the terminal by using network information, allowing or denying mobile terminal access, so as to evenly bear the network load, make full use of existing network resources, and reduce network congestion. However, in some areas where optimization is not ideal, switching failures may occur during load balancing, causing users to drop offline and resulting in poor user experience.

[0004] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present disclosure, and therefore may include information that does not constitute the prior art known to ordinary technicians in the field. Summary of the invention

[0005] The purpose of the present disclosure is to provide a load balancing method and device, a terminal, a storage medium and an electronic device, which can at least to some extent overcome the problem in the existing multi-operator co-built and shared network that switching failures may occur during load balancing, causing users to be disconnected and resulting in poor user experience.

[0006] Other features and advantages of the present disclosure will become apparent from the following detailed description, or may be learned in part by the practice of the present disclosure.

[0007] According to one aspect of the present disclosure, a load balancing method is provided, comprising: in a service cell shared by multiple network operators, sending a broadcast message to users in the service cell for each network operator, wherein the broadcast message includes a migration indication field corresponding to each network operator; receiving the migration indication field extracted by the user from the broadcast message as a response message; determining a target user according to the response message sent by the user; and performing load balancing on the target user.

[0008] In some embodiments of the present disclosure, the broadcast message includes: a system information block SIB message; the information carried in the SIB message includes: a migration indication field corresponding to one of the multiple network operators.

[0009] In some embodiments of the present disclosure, the migration indication field includes two indication bits, wherein the first indication bit indicates whether the user is allowed to perform uplink load balancing, and the second indication bit indicates whether the user is allowed to perform downlink load balancing.

[0010] In some embodiments of the present disclosure, in a service cell shared by multiple network operators, the step of sending a broadcast message to each network operator includes: periodically obtaining the load value of the service cell; determining the target network operator that meets the preset trigger conditions based on the load value; and generating a target migration indication field for the target network operator.

[0011] In some embodiments of the present disclosure, the step of determining a target network operator that meets a preset trigger condition according to a load value includes: if the load value meets the trigger condition, determining the target network operator according to a preset priority order.

[0012] According to another aspect of the present disclosure, a load balancing method is provided, comprising: receiving a broadcast message in a service cell shared by multiple network operators, the broadcast message including a migration indication field corresponding to each network operator; extracting the migration indication field from the broadcast message as a response message; and sending the response message to a network device.

[0013] According to another aspect of the present disclosure, a load balancing device is provided, including: a broadcast unit, configured to send a broadcast message to users in a service cell shared by multiple network operators for each network operator, wherein the broadcast message includes a migration indication field corresponding to each network operator; a response message receiving unit, receiving the migration indication field extracted by the user from the broadcast message as a response message; a target user determination unit, configured to determine the target user according to the response message sent by the user; and a load balancing unit, configured to perform load balancing on the target user.

[0014] According to another aspect of the present disclosure, a load balancing terminal is provided, comprising: a broadcast message receiving unit, configured to receive a broadcast message in a service cell shared by multiple network operators, the broadcast message including a migration indication field corresponding to each network operator; an extraction and analysis unit, configured to extract the migration indication field from the broadcast message as a response message; and a response message sending unit, configured to send the response message to a network device.

[0015] According to another aspect of the present disclosure, an electronic device is provided, comprising: a processor; and a memory for storing executable instructions of the processor; wherein the processor is configured to perform the above-mentioned load balancing method by executing the executable instructions.

[0016] According to another aspect of the present disclosure, a computer-readable storage medium is provided, on which a computer program is stored. When the computer program is executed by a processor, the load balancing method described above is implemented.

Therefore, this method can improve the success rate of service cell load balancing and improve user experience.

[0031] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in a variety of forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that the disclosure will be more comprehensive and complete and to fully convey the concepts of the example embodiments to those skilled in the art. The described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

[0032] In addition, the accompanying drawings are only schematic illustrations of the present disclosure and are not necessarily drawn to scale. The same reference numerals in the figures represent the same or similar parts, and their repeated description will be omitted. Some of the block diagrams shown in the accompanying drawings are functional entities and do not necessarily correspond to physically or logically independent entities. These functional entities can be implemented in software form, or implemented in one or more hardware modules or integrated circuits, or implemented in different networks and / or processor devices and / or microcontroller devices.

[0033] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present disclosure, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0034] In view of the technical problems existing in the above-mentioned related technologies, the embodiments of the present disclosure provide a load balancing method to solve at least one or all of the above-mentioned technical problems.

[0035] The terminal device (or user equipment "UE device") involved in some embodiments of the present application is any of various types of computer system devices that are mobile or portable and perform wireless communication. Examples of terminal devices include mobile phones or smart phones (e.g., iPhoneTM, AndroidTM-based phones), portable gaming devices (e.g., Nintendo DSTM, PlayStation PortableTM, Gameboy AdvanceTM, iPhoneTM), laptops, wearable devices (e.g., smart watches, smart glasses), PDAs, portable Internet devices, music players, data storage devices or other handheld devices, etc. In general, the term "UE" or "UE device" can be broadly defined as covering any electronic device, computing device and / or telecommunication device (or combination of devices) that is easily transmitted by a user and capable of wireless communication. Terminal devices operating according to the 5G standard may be referred to as new radio units (NRUs).

[0036] The network devices involved in some embodiments of the present application may include base stations with wireless communication functions, mobile switching centers, etc., or may be hubs, switches, bridges, routers, etc. For the convenience of description, the devices mentioned above are collectively referred to as network devices.

[0037] Figure 1 A schematic diagram of a wireless communication system in some embodiments of the present disclosure is shown, which includes: a first core network 110a of a construction party (first network operator), a second core network 110b of a sharing party (second network operator), a non-shared base station 120a established by the construction party, a shared base station 120b, a non-shared base station 120c established by the sharing party, a terminal device 130a of the construction party, a terminal device 130b of the construction party, a terminal device 130c of the sharing party, and a terminal device 130d of the sharing party.

[0038] A shared base station refers to a cell broadcasting a base station's network operator PLMN (Public Land Mobile Network, PLMN for short) that can be used by users in other locations. For example, a shared cell will broadcast the PLMN of a shared base station. Figure 1 The PLMN1 in the figure is the PLMN of the base station established by the construction party broadcast by the shared cell. In addition, the address of the shared cell is shared by two network operators, so the shared cell can also broadcast the PLMN2 of the base station established by the sharing party. Figure 1As shown, the terminal device 130b of the contractor and the terminal device 130c of the sharing party can both connect to PLMN1 and PLMN2 in the shared cell. The terminal device 130a of the contractor located outside the shared cell connects to PLMN1, and the terminal device 130d of the sharing party located outside the shared cell connects to PLMN2.

[0039] Among them, the base station and the terminal device can be configured to communicate through a transmission medium using any of a variety of radio access technologies (RATs), which are also referred to as wireless communication technologies or telecommunication standards, such as GSM, UMTS (associated with, for example, WCDMA or TD-SCDMA air interfaces), LTE, Advanced LTE (LTE-A), 5G New Radio (5GNR), HSPA, SGPP2CDMA2000 (e.g., 1xRTT, 1xEV-DO, HRPD, eHRPD), etc. It should be noted that if the base station is implemented in the context of LTE, it may alternatively be referred to as "eNodeB" or "eNB". It should be noted that if the base station is implemented in the context of 5G NR, it may alternatively be referred to as "gNodeB" or "gNB".

[0040] The base station may also be configured to communicate with a network (e.g., a core network of a cellular service provider, a telecommunications network such as a public switched telephone network (PSTN), and / or the Internet, among other possibilities). Thus, the base station may facilitate communications between user devices and / or between user devices and the network. In particular, a cellular base station may provide terminal devices with various communication capabilities such as voice, SMS, and / or data services.

[0041] The base station and other similar base stations (such as the base station) operating according to the same or different cellular communication standards can therefore be provided as a network of cells, which can provide continuous or nearly continuous overlapping service to terminal devices 130 series and similar devices over a geographic area via one or more cellular communication standards.

[0042] Therefore, although the base station can act as Figure 1 , each UE may also be able to receive signals from (and possibly within communication range of) one or more other cells (which may be provided by the base station and / or any other base station), which may be referred to as "neighboring cells". Such cells may also be able to facilitate communication between user devices and / or between user devices and the network. Such cells may include "macro" cells, "micro" cells, "pico" cells, and / or cells of any other various granularities that provide service area sizes. For example, a base station may be a macro cell, while a base station may be a micro cell, and other configurations are also possible.

[0043] In some embodiments, the base station may be a next generation base station, for example, a 5G New Radio (5G NR) base station or "gNB". In some embodiments, the first core network and the second core network connected to the base station may be a traditional evolved packet core (EPC) network or an NG core (NGC) network formed by different operators. In addition, the gNB cell may include one or more transmission and reception points (TRPs). In addition, a UE capable of operating according to 5G NR may be connected to one or more TRPs within one or more gNBs.

[0044] In some embodiments, the base station may be (or may include) an access point (AP). The base station may be capable of communicating using one or more wireless local area network (WLAN) communication standards. For example, the base station may be capable of communicating using the IEEE 802.11 standard (e.g., Wi-Fi).

[0045] It should be noted that the terminal device 130 series is capable of communicating using multiple wireless communication standards. For example, in addition to at least one cellular communication protocol (e.g., GSM, UMTS (associated with, for example, WCDMA or TD-SCDMA air interface), LTE, LTE-A, 5G NR, HSPA, 3GPP2CDMA2000 (e.g., 1xRTT, 1xEV-DO, HRPD, eHRPD), etc.), the terminal device UE can be configured to communicate using wireless networking (e.g., Wi-Fi) and / or peer-to-peer wireless communication protocols (e.g., Bluetooth, Wi-Fi peer-to-peer, etc.). If desired, the terminal device UE can also or alternatively be configured to communicate using one or more global navigation satellite systems (GNSS, such as GPS or GLONASS), one or more mobile television broadcast standards (e.g., ATSC-M / H or DVB-H), and / or any other wireless communication protocols. Other combinations of wireless communication standards (including more than two wireless communication standards) are also possible.

[0046] Those skilled in the art will appreciate that the number of the terminal devices 130 series may be more or less. For example, the terminal may be only one, or the terminal may be dozens or hundreds, or more. The embodiment of the present application does not limit the number and device type of the terminal.

[0047] The following will describe each step of the load balancing method in this example implementation in more detail with reference to the accompanying drawings and embodiments.

[0048] Figure 2 A flow chart of a method for performing load balancing on a network device in some embodiments of the present disclosure is shown. Figure 1 In the following example description, the shared base station 120b is used as the execution subject for example description.

[0049] like Figure 2 As shown, some embodiments of the present disclosure provide a load balancing method 200 including the following steps:

[0050] In step S210, in a service cell shared by multiple network operators, a broadcast message is sent to users in the service cell for each network operator, and the broadcast message includes a migration indication field corresponding to each network operator.

[0051] In some embodiments of the present disclosure, a serving cell shared by multiple network operators (PLMNs) may be, for example, Figure 1 In the shared base station 120b, the network device (also known as the serving cell) generates a different broadcast message for each network operator PLMN, wherein the broadcast message includes a migration indication field corresponding to each network operator PLMN.

[0052] In some embodiments of the present disclosure, the broadcast message may be SIB1, SIB2, SIB4, etc. or other types of broadcast messages, which are not particularly limited in this embodiment. The broadcast message includes a migration indication field corresponding to a specific network operator PLMN, and the migration indication field is used to indicate whether the terminal device needs to switch to another cell.

[0053] In step S220, a migration indication field extracted by the user from the broadcast message is received as a response message.

[0054] In some embodiments of the present disclosure, each user terminal connected to the serving cell receives a broadcast message from the serving cell, extracts a migration indication field from the broadcast message, and sends the migration indication field as a response message to the serving cell (network device).

[0055] In step S230, the target user is determined according to the response message sent by the user.

[0056] In some embodiments of the present disclosure, the serving cell confirms the selection of the target user in the terminal device that remains connected based on the response message sent by the user, so as to avoid the situation where the terminal device cannot be normally connected to the serving cell due to movement of the terminal device.

[0057] In step S240, load balancing is performed on the target user.

[0058] In some embodiments of the present disclosure, performing load balancing on the target user may be performing cell switching on the target user terminal, wherein it should be noted that the method of performing cell switching is not particularly limited in the present application, and those skilled in the art may refer to the records in the relevant technology when putting the technical solution of the present application into practice; for example, in some embodiments, the current serving cell initiates a switching request to multiple neighboring cells, and sends configuration information of multiple neighboring cells to the terminal, so that the terminal determines the target cell to be migrated according to the configuration information, and thereby sends an access request to the target cell to access the target cell.

[0059] The present invention proposes a load balancing method, which implements flexible management and control of user situations in which load balancing occurs in a shared network by adding a migration indication field in a broadcast message.

[0060] Furthermore, the migration indication field can distinguish the migration strategies of various operators, manage and control load balancing users, and effectively ensure the throughput and performance of customized users.

[0061] Furthermore, the response message sent by the terminal is received by the network device to avoid the situation where the signal quality of the cell currently accessed by the terminal may be further reduced due to reasons such as terminal movement, thereby causing the terminal to be unable to receive the migration indication message sent by the network device, thereby causing the cell switching failure. Therefore, this method can improve the success rate of cell switching (load balancing) and improve user experience.

[0062] In some embodiments of the present disclosure, the broadcast message includes a system information block SIB message; the information carried in the SIB message includes: a migration indication field corresponding to a network operator PLMN among multiple ones.

[0063] In some embodiments of the present disclosure, the migration indication field includes two indication bits, wherein the first indication bit indicates whether the user is allowed to perform uplink load balancing, and the second indication bit indicates whether the user is allowed to perform downlink load balancing.

[0064] The two indication bits are used to provide differentiated services for different links of users of different operators. For example, load balancing may be allowed only for uplink users or downlink users of a specific operator, thereby improving the efficiency of network equipment.

[0065] For example Figure 3 A schematic diagram showing a method for performing load balancing on a network device in some embodiments of the present disclosure is shown. Figure 3 As shown, the method provided by some embodiments of the present disclosure may include the following steps:

[0066] In step S310, the serving cell broadcasts SIB1, which carries LB_U_Barred, LB_D_Barred, LB_U_SharedBarred, and LB_D_SharedBarred for the contractor PLMN1 and the shared PLMN2, respectively. LB_U_Barred and LB_D_Barred respectively indicate that the contractor user has uplink and downlink load balancing, and LB_U_SharedBarred and LB_D_SharedBarred respectively indicate that the shared user has uplink and downlink load balancing.

[0067] Among them, uplink load balancing of the contractor's users refers to load balancing of the contractor's uplink users; downlink load balancing of the contractor's users refers to load balancing of the contractor's downlink users; uplink load balancing of the sharing party users refers to load balancing of the sharing party's uplink users; downlink load balancing of the sharing party users refers to load balancing of the sharing party's downlink users.

[0068] In step S320 to step S330, the LB_U_Barred and LB_D_Barred fields of the contractor PLMN1 are determined respectively, and step S340 is executed to send a SIB1 message carrying LB_U_Barred and LB_D_Barred to the contractor PLMN1.

[0069] Specifically, in step S320, it is determined whether uplink load balancing is allowed for the PLMN1 user of the contractor. If yes, LB_U_Barred is set to 0, otherwise, LB_U_Barred is set to 1.

[0070] Specifically, in step S340, it is determined whether downlink load balancing is allowed for the user of the contractor PLMN1. If yes, LB_D_Barred is set to 0, otherwise, LB_D_Barred is set to 1.

[0071] In step S350 to step S360, the LB_U_SharedBarred and LB_D_SharedBarred fields of the sharing party (PLMN2) are determined respectively, and step S370 is executed to send a SIB1 message carrying the LB_U_SharedBarred and LB_D_SharedBarred fields to the sharing party PLMN2.

[0072] Specifically, in step S320, it is determined whether uplink load balancing is allowed for the shared PLMN2 user. If yes, LB_U_SharedBarred is set to 0; otherwise, LB_U_SharedBarred is set to 1.

[0073] Specifically, in step S340, it is determined whether downlink load balancing is allowed for the shared PLMN2 user. If yes, LB_D_SharedBarred is set to 0, otherwise, LB_D_SharedBarred is set to 1.

[0074] Through the above steps, the serving cell (network device) can send different migration indication fields to different network operators, so as to implement load balancing according to the network operators.

[0075] Figure 4 A flowchart of a method 400 for performing load balancing on a terminal in some embodiments of the present disclosure is shown.

[0076] In step S410, the load value of the serving cell is obtained periodically.

[0077] In some embodiments of the present disclosure, the load value may be the number of connected users of the serving cell.

[0078] In some other embodiments of the present disclosure, the load value may also be a utilization rate of radio resources of the serving cell, for example, a utilization rate of physical resource blocks (PRBs) at the network device side.

[0079] In addition, in some embodiments, the load value of the serving cell may be determined by combining the number of connected users and the utilization rate of wireless resources.

[0080] In some embodiments of the present disclosure, the load value may also include an uplink and downlink load value. For example, the number of connected users of the uplink and the number of connected users of the downlink of the serving cell are obtained respectively. For another example, the uplink radio resource utilization rate and the downlink radio resource utilization rate of the serving cell are obtained respectively.

[0081] In step S420, a target network operator that meets a preset trigger condition is determined according to the load value.

[0082] In some embodiments of the present disclosure, the trigger condition may include setting other network operators other than the contractor operator in the serving cell as the target network operator if the number of connected users in the serving cell exceeds a set threshold.

[0083] In some other embodiments of the present disclosure, the trigger condition may include setting other network operator users other than the contractor operator in the serving cell as the target network operator if the wireless resource utilization rate of the serving cell exceeds a set threshold.

[0084] In some embodiments of the present disclosure, the trigger condition may also be set differently according to the uplink and downlink. For example, the trigger condition may include setting other network operators other than the contractor operator in the serving cell as the target network operator if the number of uplink connected users in the serving cell exceeds the connection number threshold of the uplink or the number of downlink connected users exceeds the connection number threshold of the downlink.

[0085] For example, the trigger condition may include setting other network operators other than the contractor operator in the service cell as the target network operator if the uplink wireless resource utilization of the service cell exceeds the uplink wireless resource utilization threshold or the downlink wireless resource utilization exceeds the downlink wireless resource utilization threshold.

[0086] In the embodiments of the present disclosure, the triggering conditions are not limited.

[0087] In step S430, a target migration indication field of the target network operator is generated.

[0088] In some embodiments of the present disclosure, for example Figure 3 Steps S350 to S360 in the above method are to broadcast the migration indication field to one or more other network operators of the sharing party.

[0089] In some embodiments of the present disclosure, uplink load balancing and / or downlink load balancing is determined to occur according to the uplink and downlink of the target network operator, so as to generate two bits of the migration indication field respectively.

[0090] By periodically obtaining the load value of the service cell, if it is found that the load value meets the conditions for triggering load balancing, the number of users of some network operators in the service cell is adjusted to achieve the purpose of controlling the load of the entire service cell, thereby maintaining the network quality of the service cell and ensuring the user experience.

[0091] like Figure 4 As shown, step S420 may further include the following steps:

[0092] Step S420a: If the load value meets the preset trigger condition, the target network operator is determined according to the preset priority order.

[0093] In some embodiments of the present disclosure, the preset priority order may be a pre-set order that the priority of the network operator of the sharing party is higher than the priority of the network operator of the contractor. Then, when the triggering condition for executing load balancing is met, the priority migration of the network operator users of the sharing party can be determined according to this rule. In some embodiments, if there are multiple shared network operators, the priority order of the sharing parties can also be pre-set, for example, the network operator of sharing party A is higher than the network operator of sharing party B, which is higher than the network operator of sharing party C, which is higher than the network operator of contractor D. Then, the network users of sharing party A are preferentially used as the target network operators for load balancing.

[0094] In some embodiments of the present disclosure, priorities can also be set according to the uplink and downlink links of different operators. For example, the uplink of the network operator of sharing party A is higher than the uplink of the network operator of sharing party B, but the downlink of the network operator of sharing party B is higher than the downlink of the network operator of sharing party A.

[0095] This application can meet the customized configuration requirements of different operators by setting priorities for multiple network operators in a shared network, improve the flexibility of balancing feature configuration of each operator in the shared network, and thus provide users with higher network performance and service quality.

[0096] Figure 5 FIG. 5 shows a flow chart of a method 5500 for executing a load balancing operation in a terminal in some embodiments of the present disclosure. Figure 5 As shown, method 500 may include the following steps:

[0097] In step S510, a broadcast message is received in a service cell shared by multiple network operators, where the broadcast message includes a migration indication field corresponding to each network operator.

[0098] In some embodiments of the present disclosure, the broadcast message includes: a system information block SIB message; the information carried in the SIB message includes: a migration indication field corresponding to one of the multiple network operators (PLMN).

[0099] In some embodiments of the present disclosure, the migration indication field includes 2 indication bits, wherein the first indication bit indicates whether the user is allowed to perform uplink load balancing, and the second indication bit indicates whether the user is allowed to perform downlink load balancing. For example, "0" in the first indication bit in the migration indication field indicates that the user is allowed to perform uplink load balancing; "1" indicates that the user is prohibited from performing uplink load balancing; "0" in the second indication bit indicates that the user is allowed to perform downlink load balancing; "1" indicates that the user is prohibited from performing downlink load balancing.

[0100] In step S520, a migration indication field is extracted from the broadcast message as a response message.

[0101] In some embodiments of the present disclosure, if the current serving cell (network device) determines that the uplink and downlink load balancing of users in the contractor PLMN1 is prohibited, a first SIB1 message carrying a migration indication field "11" is sent to the user of PLMN1; if the current serving cell (network device) determines that the uplink and downlink load balancing of users in the shared party PLMN2 is allowed, a second SIB1 message carrying a migration indication field "00" is sent to the user of PLMN2. Therefore, when the PLMN1 user in the serving cell receives the first SIB1, the migration indication field "11" is extracted from the first SIB1 and sent to the serving cell (network device), and the PLMN2 user in the serving cell receives the second SIB1, and the migration indication field "00" is extracted from the second SIB1 and sent to the serving cell (network device).

[0102] In step S530, a response message is sent to the network device.

[0103] In some embodiments of the present disclosure, before step S510, the following may also be included: regularly acquiring a load value of a serving cell; determining a target network operator that meets a preset trigger condition according to the load value; and generating a target migration indication field of the target network operator.

[0104] In some embodiments of the present disclosure, the step of determining a target network operator that meets a preset trigger condition according to the load value may further include: if the load value meets the trigger condition, determining the target network operator according to a preset priority order.

[0105] The above embodiments are respectively Figures 2 to 4 The steps performed on the described network device side are corresponding and will not be repeated here.

[0106] Figure 6 FIG. 2 is an interactive schematic diagram of a load balancing method in some embodiments of the present disclosure. Figure 6 As shown, the load balancing method includes the following steps:

[0107] In step S610, the network device 600D obtains a load value of a serving cell.
