[0002] In mobile communication technology, no load balancing control is performed before a terminal initiates connection establishment to a base station, and generally, congestion control is performed only in the process of initiating connection establishment. For example, a back-off mechanism, when congestion occurs, the base station indicates the terminal to back off and gives a time range for back-off in a second RRC (Radio Resource Control) connection establishment message, and the terminal, after receiving the message, randomly selects a back-off time within the suggested back-off time period and initiates RRC connection establishment when the back-off time arrives. In this process, a certain loss is caused to the system resources, and a certain degree of impact is caused to the load of the system; in addition, in this process, the terminal also consumes a certain power consumption, which is not conducive to energy saving.

[0048] In order to better understand the embodiments of the present application, the following terms are explained as follows:

[0049] RRC is used to process third layer information of a control plane between a UE (User Equipment) and an eNB (Evolved Node-B). The first layer is a physical layer (Physical Layer), the second layer is a medium access control layer (Medium Access Control), and the third layer is RRC. RRC allocates wireless resources and sends related signaling. The main part of control signaling between a UE and a UTRAN (UMTS Terrestrial Access Network) is RRC messages.

[0050] LTE (Long Term Evolution) is also referred to as E-UTRA or E-UTRAN. It is a long-term evolution of the UMTS (Universal Mobile Telecommunications System) technology standard formulated by the 3GPP (The 3 rd Generation Partnership Project) organization.

[0051] EPC (Evolved Packet Core) is a core network of a 4G mobile communication network.

[0052] eNB (Evolved Node-B): In the standard of LTE, eNB is used to represent the base station, corresponding to the user UE. eNB is the bridge between UE and the evolved core network EPC in LTE.

[0053] MME (Mobility Management Entity) is the key control node of 3GPP protocol LTE access network, which is responsible for the positioning of idle mode UE, paging, relay and other processes, that is, MME is responsible for the processing of signaling.

[0054] S1 interface is the communication interface between eNB and EPC, which divides the LTE system into wireless access network and core network.

[0055] X2 interface is the interconnection interface between eNBs, which supports direct transmission of data and signaling.

[0056] SIM (Subscriber Identification Module): SIM card needs to be installed on digital mobile phone to identify user identity.

[0057] LTE Attach is the LTE connection process, and the mobility management state of UE can be divided into LTE detach and LTE attach. Through the Attach process, UE can enter the RRC Connected (RRC connection) state, at which time UE obtains IP address and predefined EPS bearer.

[0058] TAU (Tracking Area Update): When UE moves from one TA (Tracking Area) to another TA, it must re-register the location on the new TA to inform the network to change the stored UE location information. This process is called TAU.

[0059] R16 (Release 16): The first stage standard of 5G (5-Generation wire telephone technology) is R15 (Release 15); the second stage standard is R16 (Release 16).

[0060] SIB (System Information Block, system information block), system information is divided into MIB (Master Information Block, master information block) and multiple SIB (System Information Block, system information block).

[0061] NAS (Non-access Stratum, non-access layer) exists in the wireless communication protocol stack of UMTS (Universal Mobile Telecommunications System, universal mobile communication system), as a functional layer between the core network and the user equipment, which supports signaling and data transmission between the two.

[0062] HSS (Home Subscriber Server, home subscriber server) is an important part of the control layer in IMS (IP Multimedia Subsystem, IP multimedia subsystem). The information that HSS can process includes: user identification, numbering and address information; user security information, i.e. network access control information for authentication and authorization; user location information, i.e. HSS supports user level, stores location information; user list information.

[0063] UE_ID (user group) is contained in the paging message of S1, which is calculated by taking the modulus of 1024 of IMSI (International Mobile Subscriber Identification Number, international mobile subscriber identification number).

[0064] SIM card (Subscriber Identification Modul, subscriber identification module) is applied to mobile communication equipment to connect the network.

[0065] When the terminal interacts with the network, a large number of terminals of the same type usually have the demand of reporting services at the same time due to the same service type, and if connection establishment is initiated at the same time, it will bring certain pressure to the system resources, resulting in congestion. However, under normal circumstances, the services reported by the terminal have a certain delay tolerance, so it can be considered to access according to the discrete delay of the delay tolerance, to reduce the load pressure of the network. In addition, for a large number of terminals of different types simultaneously initiating services, the delay tolerance of the service type of different types of terminals usually has certain differences, so the difference of delay tolerance of different types of terminals can be considered to realize discrete access of different types of terminals.

[0066] The following will be described in conjunction with embodiments:

[0067] Embodiment one

[0068] The embodiment of the present application provides a load balancing method, which is used in a mobile communication device, and when the method is executed, the load pressure of a network can be reduced, different time delay discretization accesses are considered for different types of terminal UE services, the function realized by the method can be realized by calling program code of a processor in the mobile communication device, and of course the program code can be stored in a computer storage medium, so the mobile communication device at least comprises the processor and the storage medium.

[0069] Figure 1 A flowchart for realizing the method for controlling terminal access to a network is shown in the embodiment of the present application, as shown in the figure, the method comprises the following steps. Figure 1

[0070] In step S101, a base station determines classification information of a terminal to be accessed.

[0071] Here, the classification information of the terminal UE can be classification results obtained by the base station eNB after classifying the terminal UE to be accessed, the base station eNB first acquires related parameters of the terminal UE, and then classifies the terminal UE according to the parameters. The classification can be performed according to different standards, for example, according to the service type, historical service or access type of the terminal UE and the like. The classification information of the terminal UE can also be information related to the category of the terminal UE directly sent by the terminal UE to the base station eNB.

[0072] In step S102, the base station configures load balancing parameters for the terminal to be accessed according to the classification information.

[0073] Here, the base station eNB configures corresponding load balancing parameters for each type of terminal UE according to the classification results, and the service types of the same type of terminal UE are usually the same, and have the demand of reporting services at the same time. Here, the base station eNB configures the same load balancing parameters for each type of terminal UE service, which actually considers that each type of terminal UE service has the same time delay tolerance, so as to ensure that the same type of terminal UE can access in time. Different types of terminal UEs can have different load balancing parameters, so as to be distributed in different access times, and conflicts can be avoided.

[0074] In step S103, the base station controls the terminal to be accessed to access with a delay according to the load balancing parameters.

[0075] ​Here, the base station eNB controls the terminal UE to access at the corresponding time according to the delay corresponding to the configured load balancing parameter. The load balancing parameter here can indicate a time period, such as a backoff time, that is, terminals UE of the same type access within this backoff time period. At this time, terminals UE of the same type can be simultaneous access or discrete access, as long as it conforms to the configured load balancing parameter.

[0076] In other embodiments, the base station determines the classification information of the terminal to be accessed, including:

[0077] Step S101a, the base station acquires the subscription information of the terminal to be accessed;

[0078] The subscription information includes service type information, historical service information or access type information.

[0079] The subscription information here is called UE differentation information, which is service-related information carried by the terminal UE. The UE differentation information can include service type information, historical service information or access type information, etc. The access type information includes initial random access and re-random access. These UE differentation information represents the type of each terminal UE to be accessed to the base station eNB.

[0080] Step S101b, the base station classifies the terminal according to the subscription information of the access terminal, and obtains the classification information of the access terminal.

[0081] The base station eNB classifies the terminal UE according to the above-mentioned UE differentation information, which can be performed in two ways:

[0082] First, classify according to the service type of the terminal UE, that is, classify according to the service type information or historical service information in the UE differentation information.

[0083] Second, classify according to the access type of the terminal UE, that is, classify according to whether the access type of the terminal UE is initial random access or re-random access.

[0084] By classifying the terminal UE in the above two ways, different load balancing parameters can be configured for terminals of different service-related types or access types to achieve load balancing of different types of terminals.

[0085] In other embodiments, the base station controls the terminal to be accessed to access with delay according to the load balancing parameter, including:

[0086] The base station controls the terminal to delay access by sending a system information block (SIB) message carrying a control instruction with the load balancing parameter.

[0087] Here, the base station eNB enables the terminal UE to perform the load balancing strategy, that is, the base station eNB controls the terminal UE to delay access according to the configured load balancing parameter. The base station eNB carries the control instruction with the configured load balancing parameter in the system information block (SIB) message, and sends it to the terminal UE together with other instructions in the SIB message. After receiving the related instruction, the terminal UE determines the delay access time according to the load balancing parameter therein and performs the corresponding delay access.

[0088] In other embodiments, the load balancing parameter includes a backoff time.

[0089] The base station controls the terminal to delay access according to the load balancing parameter, including:

[0090] Step S103a, the base station determines the delay access time according to the backoff time.

[0091] Step S103b, the base station controls the terminal to access at the delay access time.

[0092] Here, the load balancing parameter includes a backoff time, which is a delay time period. The terminal UE can determine an access time according to the backoff time and access at the access time, thereby achieving the purpose of delay access.

[0093] In other embodiments, for the case of changing the subscription information, the method further includes:

[0094] Step S11, the base station sends the subscription information of the terminal to be accessed to the mobility management entity (MME).

[0095] Step S12, when the subscription information changes, the base station receives the changed subscription information of the terminal to be accessed sent by the mobility management entity (MME).

[0096] The subscription information includes initial subscription information and changed subscription information. The initial subscription information is the subscription information carried by the terminal itself. The changed subscription information is sent to the mobility management entity (MME) by the home subscription user server (HSS) after changing the subscription information, and is sent to the base station by the mobility management entity (MME).

[0097] Step S13, the base station sends the changed subscription information to the terminal to be accessed.

[0098] The initial subscription information of the terminal UE, i.e., the initial UE differentiation information, can be stored in the SIM card of the terminal UE, and when the network initiates a change of the UE differentiation information of the terminal UE, the terminal UE needs to store the changed UE differentiation information in the SIM card again.

[0099] The terminal UE first sends the current UE differentiation information to the MME, the MME sends the current UE differentiation information to the HSS, and simultaneously sends a change request, the HSS returns the changed UE differentiation information to the base station eNB through the MME. Finally, the base station eNB sends the changed UE differentiation information to the terminal UE, and the terminal UE stores the changed UE differentiation information. Reference Figure 4C The flow is shown.

[0100] Embodiment two

[0101] Another method for controlling terminal access to a network is provided in the embodiments of the application, as shown in the method, which comprises: Figure 2

[0102] Step S201, the base station acquires the access time of the terminal to be accessed;

[0103] Here, the base station eNB determines the next access time of the terminal UE, i.e., the next access time. The purpose is to predict whether the suitable system load condition can support the direct access of the terminal UE, and if not, load balancing is needed.

[0104] Step S202, the base station determines whether load balancing is needed for the terminal to be accessed according to the access time;

[0105] The base station eNB predicts whether load balancing is needed at the next access time of the terminal UE according to the historical load condition of the system and the current load balancing condition. When load balancing is not needed, the terminal UE can be directly accessed at the next access time.

[0106] Step S203, when the base station determines that the terminal to be accessed needs load balancing, the base station acquires the subscription information of the terminal to be accessed;

[0107] The subscription information includes service type information, historical service information or access type information.

[0108] ​The subscription information here is called UE differentation information, which is the service related information carried by the terminal UE. The UE differentation information can include service type information, historical service information or access type information, etc. The access type information includes initial random access and re-random access. These UE differentation information represents the type of terminal UE to be accessed to each base station eNB.

[0109] Step S204, the base station classifies the terminal according to the subscription information of the terminal to be accessed, and obtains classification information of the terminal to be accessed;

[0110] The base station eNB classifies the terminal UE according to the above-mentioned UE differentation information, which can be performed in two ways:

[0111] First, according to the service type of the terminal UE, that is, according to the service type information or historical service information in the UE differentation information.

[0112] Second, according to the access type of the terminal UE, that is, according to the initial random access or re-random access type of the terminal UE.

[0113] By classifying the terminal UE in the above two ways, different load balancing parameters can be configured for different service related types or access types of the terminal, so as to realize load balancing of different types of terminals.

[0114] Step S205, the base station configures load balancing parameters for the terminal to be accessed according to the classification information;

[0115] Here, the base station eNB configures corresponding load balancing parameters for each type of terminal UE according to the classification result. The service types of the same type of terminal UE are usually the same, and have the demand of reporting services at the same time. Here, the base station eNB configures the same load balancing parameters for each type of terminal UE service, which actually considers that each type of terminal UE service has the same delay tolerance, so as to ensure that the same type of terminal UE can access in time. Different types of terminal UE can have different load balancing parameters, so as to be distributed in different access time and avoid conflict.

[0116] Step S206, the base station controls the terminal to be accessed to perform load balancing and delay access at the access time according to the load balancing parameters.

[0117] Here, the base station eNB controls the terminal UE to access at the time corresponding to the delay of the load balancing parameter according to the configured load balancing parameter. The load balancing parameter here can indicate a time period, such as a back-off time, that is, the same type of terminal UE accesses within this back-off time period. At this time, the same type of terminal UE can be simultaneous access or discrete access, as long as it conforms to the configured load balancing parameter.

[0118] The access time here is actually the initial time when the terminal UE hopes to access, rather than the actual access time. The base station eNB controls the load balancing at this access time, that is, the actual access of the terminal UE is based on another access time obtained according to the delay of the load balancing parameter at this access time. Thus, the corresponding terminal UE is controlled for load balancing by prediction.

[0119] In other embodiments, the base station determines whether the terminal to be accessed needs to be load balanced according to the access time, comprising:

[0120] Step S206a, the base station acquires the historical load state of its own system;

[0121] Step S206b, the base station determines whether the terminal to be accessed needs to be load balanced at the access time according to the subscription information of the terminal to be accessed and the historical load state of its own system.

[0122] The base station eNB predicts whether the terminal UE needs to be load balanced at the access time of the terminal UE by acquiring the historical load state of its own system and the UE differentation information of the terminal UE. The historical load state here can be determined according to the load state within a time period according to actual conditions, for example, the load state at the same time in the past few days, or the average load state according to whether it is a time period prone to congestion.

[0123] The embodiment of the application also provides another method for controlling terminal access to a network:

[0124] Step S21, the base station receives the first load balancing parameter and the first historical load information sent by the adjacent cell base station;

[0125] Step S22, the base station determines the classification information of the terminal to be accessed;

[0126] Step S23, the base station configures the second load balancing parameter for the terminal to be accessed according to the classification information;

[0127] Step S24, the base station determines its own second historical load information;

[0128] Step S25, the base station controls the terminal to delay access according to the first load balancing parameter, the second load balancing parameter, the first historical load information and the second historical load information.

[0129] The method of controlling the terminal to access the network in the embodiment can be applied to the same cell or different cells when it is determined that load balancing is needed. For example, when the current cell is congested, the terminal UE can be configured to access the neighboring cell to reduce the load of the current cell by referring to the load of the neighboring cell. The base station eNB of the current cell and the base station eNB of the neighboring cell need to communicate with each other and report the system information of each other. The system information includes the historical load information of the base station eNB and the load balancing parameter configured by the base station eNB. Through the information, the base station eNB can determine whether the neighboring cell is congested and whether it is suitable to access the neighboring cell for the terminal UE of the current cell. By comparing the system information of the neighboring cell base station eNB and the system information of the base station eNB, the base station eNB can control the terminal UE to delay access to the appropriate cell according to the load balancing parameter.

[0130] Embodiment Three

[0131] Another method of controlling the terminal to access the network is provided in the embodiment of the application, as shown in the figure, the method comprises: Figure 3

[0132] Step S301, the terminal reports the subscription information of the terminal to the base station;

[0133] Step S302, when the base station classifies the terminal according to the subscription information and obtains the classification information, the terminal obtains the load balancing parameter configured by the base station according to the classification information;

[0134] Step S303, the terminal delays access according to the load balancing parameter.

[0135] The load balancing method of the embodiment is applied to the terminal UE. The terminal UE sends the subscription information, that is, the UE differentation information to the base station eNB. The base station eNB classifies the terminal UE according to the UE differentation information and configures the corresponding load balancing parameter for the terminal UE according to the classification information. After the terminal UE obtains the load balancing parameter, the terminal UE delays access according to the time specified by the load balancing parameter.

[0136] In other embodiments, the terminal delays access according to the load balancing parameter, comprising:

[0137] ​The terminal determines a back-off time according to the load balancing parameter, determines an access time in a period from a current time to the back-off time, and accesses at the access time.

[0138] Alternatively,

[0139] The terminal determines an access time according to a terminal device code UE_ID, and accesses at the access time.

[0140] The terminal performs a delay access, including the following two methods:

[0141] First, a random delay access. The terminal UE knows the maximum back-off time according to the load balancing parameter broadcasted by the system message, i.e., the UEdifferentation information of the terminal UE. The terminal UE can randomly select an access time between 0 and the maximum back-off time to re-access.

[0142] Second, a discrete access based on UE_ID. The terminal UE determines a back-off time according to a discrete method agreed with the base station, and determines an access time. For example, a delay coefficient of the maximum back-off time is determined, and the method for calculating the back-off time is, for example, UE_ID mod X divided by X, i.e., (UE_ID mod X) / X, wherein X is a coefficient of the agreed maximum back-off time.

[0143] In other embodiments, the method further includes:

[0144] Step S31, the terminal respectively acquires the load balancing parameters configured by the current cell base station and the adjacent cell base station.

[0145] Step S32, the terminal determines a to-be-accessed base station according to the load balancing parameters configured by the current cell base station and the adjacent cell base station.

[0146] Step S33, the terminal delays to access the to-be-accessed base station according to the load balancing parameter configured by the to-be-accessed base station.

[0147] The method for controlling the terminal to access the network in the embodiment can not only be applied to the terminal accessing the current cell, but also be applied to the terminal accessing the adjacent cell. For example, when the current cell is congested, the load of the current cell can be reduced by referring to the load of the adjacent cell and configuring the terminal UE to access the adjacent cell. Here, the current cell base station eNB and the adjacent cell base station eNB need to communicate with each other and report the system information of each other. The system information includes the historical load information of the base station eNB and the load balancing parameter configured by the base station eNB.

[0148] The terminal UE determines the accessed cell according to the received enabling information of load balancing of the current cell and the neighboring cells in the system message, the configuration information of load balancing, and the quality of service of each cell, and determines the access opportunity according to the delay access method. For example, the load balancing strategy of the first candidate cell is first judged according to the cell reselection rule whether it can meet the demand of the UE, if not, the second candidate cell is then judged, until the cell to be accessed is selected.

[0149] Embodiment four

[0150] The embodiment of the present application provides a method for controlling terminal access to a network, as shown in the figure, the method comprises: Figure 4A

[0151] Step S401, the base station eNB classifies the terminals UE which need to perform load balancing;

[0152] Step S402, the base station eNB configures the corresponding load balancing parameters according to the classification result;

[0153] Step S403, the base station eNB performs delay access according to the configured load balancing parameters.

[0154] Here, the classification of the UE includes the following two different ways:

[0155] First, according to the service type of the UE, the base station eNB obtains the subscription information of the terminals in the cell from the MME through the public signaling of the S1 interface, which is called UE differentation information, and classifies. According to the classification result, the corresponding load balancing parameters are configured. The UE differentation information includes service type information, historical service information, etc.

[0156] Here, the load balancing parameters are the parameters required when the terminal performs load balancing, such as the backoff time (timer). The backoff time is based on the original trigger random access time as the time base point, and a maximum delay time is configured.

[0157] Second, according to the random access type of the UE, the base station eNB classifies according to whether the random access type of the UE is initial random access or re-random access.

[0158] After classifying the UE according to the above two methods, the corresponding load balancing parameters are configured. In this embodiment, the load balancing parameters refer to the backoff time. The time domain discrete delay access is performed according to the configured backoff time. The time domain discrete access is that when the UE is triggered to initiate access, a time is randomly selected from 0 to the backoff time according to the configured backoff time, and the access is performed at this time.

[0159] ​In other embodiments, the load balancing method described above, as shown in Figure 4B includes the following steps:

[0160] Step S411, the base station eNB receives the UE differentation information reported by the UE;

[0161] Step S412, the base station eNB acquires the historical load status of the system;

[0162] Step S413, the eNB predicts whether the UE needs to enable the load balancing strategy at the next access according to the acquired UE differentation information and the historical load status of the system;

[0163] Step S414, if the UE needs to enable the load balancing strategy, the UE is instructed to enable the load balancing strategy by carrying the indication information;

[0164] Step S415, the UE accesses the network according to the load balancing strategy.

[0165] The method for the UE to report the UE differentation information includes that the UE reports the UE differentation information to the MME through the NAS message, and the UE differentation information at least includes the historical service information. Then the MME transfers the UE differentation information to the base station eNB through the S1 interface information.

[0166] The method for the base station eNB to carry the indication information includes that the eNB carries the indication information to instruct the UE to enable the load balancing strategy at the next access through the RRC message, and carries the configuration parameter information of the load balancing such as the delay time or the backoff time. The RRC message includes the RRC release message (RRC release connection message) or the RRC reconfiguration message (RRC reconfiguration message) and the like.

[0167] In other embodiments, the initial subscription information UE differentation information stored by the UE is stored in the SIM card, and the initial UE differentation information is enumerated as follows:

[0168] UE differentation ENUMERATED{serving_id0,serving_id1,serving_id2,…,serving_id9}

[0169] Wherein, the serving_id is the service code, representing a service category.

[0170] When the UE differentation information is changed, the network side initiates a change information notification process, and the changed UE differentation information parameters can be returned to the UE in the attach process or the TAU process. For example, the UE differentation information is changed in the attach process, and the UE differentation information is returned to the UE in the attach process. Figure 4C For the flowchart of completing the UE differentation parameter change in the attach process, the following steps are included.

[0171] Step S421, the terminal UE sends a link request.

[0172] Step S422, the base station eNB sends the received initial UE differentation information of the terminal to the MME.

[0173] Step S423, the MME sends a UE differentation information change request to the HSS.

[0174] Step S424, the HSS returns the changed UE differentation information to the MME.

[0175] Step S425, the MME returns the initial environment switching request and the received connection request message to the base station eNB, with the changed UE differentation information.

[0176] Step S426, the base station eNB returns the initial environment switching request and the received connection request message to the terminal UE, with the changed UE differentation information.

[0177] Step S427, the terminal UE stores the changed UE differentation information.

[0178] In other embodiments, the UE reports the UE differentation information to the eNB. The UE reports the UE differentation information to the MME through the base station eNB by means of a NAS message, and the UE differentation information includes historical service information. Then, the MME returns the mapping relationship of the delay time corresponding to the UE differentation information to the eNB by means of public signaling of the S1 interface, such as S1Setup Response (S1 setup response signaling) or MMEConfiguration Update (MME configuration update signaling).

[0179] The mapping relationship can be represented as shown in Table 1.

[0180] UE differentation delay Serving_id 0 Nx 0 Serving_id 1 Nx 1 … … Serving_id 9 Nx 9

[0181] Table 1

[0182] In other embodiments, the base station eNB enables the UE to perform the load balancing strategy, and the method of applying the fallback mechanism can include the following two ways:

[0183] First, all R16 UEs perform fallback operations;

[0184] Second, some R16 UEs perform fallback operations.

[0185] Among them, the second way includes the following cases:

[0186] 1. Enable some UEs to fallback in the SIB message based on the service type (serving_id) in the UE differentiation information;

[0187] 2. Enable some UEs to fallback in the SIB message based on the UE category AC (access class service access priority type);

[0188] 3. The UE performs fallback based on historical service information in the UE differentiation information, that is, the UE determines whether to perform fallback according to the sensitivity of historical service to delay.

[0189] In other embodiments, the UE performs delay access when it is indicated to enable the load balancing strategy. Including the following two methods:

[0190] First, randomize the delay access. The terminal UE learns the maximum fallback time according to the load balancing parameters broadcasted by the system message, i.e., its own UE differentiation information. The terminal UE can randomly select an access time between 0 and the maximum fallback time to re-access.

[0191] Second, discrete access based on UE_ID. The terminal UE determines the fallback time and determines the access time according to the agreed discrete method with the base station. For example, determine the delay coefficient of the maximum fallback time, and the method of calculating the fallback time is, for example, UE_ID modulo X divided by X, i.e., (UE_ID mod X) / X, where X is the agreed coefficient of the maximum fallback time.

[0192] In other embodiments, the above method of controlling terminal access to the network is applied to the cell level within the cell.

[0193] The base station eNB broadcasts the load balancing configuration information of the cell level, and determines whether to enable the load balancing strategy according to the current load situation or the predicted load situation of the system in the future period of time in the broadcast system message, and provides corresponding indication information in the system message to the UE.

[0194] The base station eNB acquires the UE differentation information in the cell from the MME through the public signaling of the S1 interface to configure the corresponding back-off time.

[0195] After receiving the enabling information of load balancing and the load balancing parameters (i.e. the configured back-off time) in the system message, the UE determines the next access time according to the delay access method (e.g. the random delay access method, the discretization access method based on UE_ID, etc.). Figure 4D The flow of reporting the UE differentation information by the UE, receiving the enabling information of load balancing and the load balancing parameters to determine the next access time is shown, including the following steps:

[0196] Step S431, the terminal UE reports the UE differentation information to the MME through the base station eNB;

[0197] Step S432, the MME transmits the UE differentation information in the cell through the public signaling of the S1 interface;

[0198] Step S433, the base station eNB broadcasts the system message, which contains the configuration information of the load balancing parameters;

[0199] Step S434, the application of the load balancing strategy is determined according to the configuration information of the load balancing and the UE differentation information.

[0200] In other embodiments, the load balancing method of the UE can be applied in the cell or between cells. As shown, Figure 5A The load balancing method in the cell includes the following steps:

[0201] Step S501, the UE reports the UE differentation information, which contains the possible historical traffic information;

[0202] Step S502, the MME transmits the UE differentation information in the cell to the eNB through the public signaling of the S1 interface;

[0203] Step S503, the eNB predicts the congestion condition of the system when the UE reports the traffic next time according to the historical traffic information contained in the UE differentation information and the historical information of the system, and determines whether to enable the load balancing strategy;

[0204] Step S504, the eNB indicates the access time of next access of the UE by RRC message, and carries the load balancing parameters such as back-off time. The RRC message here can include RRC release message or RRC reconfiguration message;

[0205] Step S505, the UE releases the connection and records the load balancing strategy.

[0206] As shown in Figure 5B , the load balancing method for the UE between cells includes the following steps:

[0207] Step S511, the UE reports the UE differentation information, wherein the UE differentation information contains possible historical service information;

[0208] Step S512, the MME transfers the UE differentation information to the eNB by public signaling of S1 interface;

[0209] Step S513, the eNBs interact the load state information of their own systems and the load balancing parameters;

[0210] Step S514, the eNB determines the load balancing parameters of the system when the UE reports service next time according to the historical information of the UE and the historical information of the system;

[0211] Step S515, the eNB carries the load balancing parameters of the current cell and the neighbor cells by RRC message;

[0212] Step S516, the UE determines the cell to access according to the load balancing parameters of the current cell and the neighbor cells, the cell reselection result information and the UE differentation information when accessing next time.

[0213] In other embodiments, as shown in Figure 5C , the load balancing method between cells can further include the following steps:

[0214] Step S521, the UE reports the UE differentation information to the eNB;

[0215] Step S522, the MME transfers the UE differentation information to the eNB by public signaling of S1 interface;

[0216] Step S523, the eNBs interact the load state information of their own systems and the load balancing parameters;

[0217] Step S524, the eNB of the access cell broadcasts the load balancing parameters of the current cell and the neighbor cells.

[0218] In step S525, the UE integrates the cell reselection result, the cell load balancing parameter and the UE differentiation information to determine the cell to be accessed.

[0219] The load state information of the cell and the neighboring cells, the load balancing parameter configuration information and the load balancing enabling indication information are broadcast in the system message.

[0220] If the UE acquires the state information of the cell and finds that the load of the cell is heavy, the load balancing is enabled and the configuration parameter of the possible load balancing, i.e. the maximum delay value of the delay access, is also configured to be a large value, the UE can consider to access from the neighboring cell under the premise of meeting the quality of service and further consider the load state of the neighboring cell and the load balancing parameter configuration.

[0221] The eNBs exchange the respective information through the X2 structure, and one of the eNBs broadcasts the information of the cell and the neighboring cells in the system message.

[0222] The UE comprehensively considers and determines the cell to be accessed according to the received load balancing enabling information and load balancing configuration information of the cell and the neighboring cells in the system message and according to the quality of service of each cell and determines the access opportunity according to the delay access method. For example, the load balancing strategy of the first candidate cell is first judged according to the cell reselection rule to see whether it can meet the demand of the UE, and if not, the second candidate cell is then judged until the cell to be accessed is selected.
