Abstract

Disclosed are a method, a terminal, and a system for controlling terminal access. According to the method, a network transmits to a terminal access control target types and access control information corresponding to the access control target types; and, when the terminal needs access, the terminal obtains the access control information corresponding to the terminal according to the terminal's own access control target type and according to the access control information corresponding to access control target types transmitted by the network. The access control information is for instructing a terminal about whether access is permitted or for instructing the terminal to gain access according to a ratio. The terminal carries out access control according to the obtained access control information. The present invention solves the communication quality issue of network congestion arising from the incapability of existing access control mechanisms to process or avoid a large volume of M2M terminal access. The present invention effectively protects a network and ensures communication quality.

Description

The present invention relates to the field of wireless communications, and in particular to a method, a terminal, and a system for controlling terminal access. BACKGROUND In an existing protocol, in order to control access behavior of a user equipment, an access control mechanism is introduced in the protocol. The mechanism specifies a total of 16 access classes (AC, Access Class), where AC 0~9 corresponds to an ordinary call, AC 10 corresponds to an emergency call, and AC 11~15 corresponds to other special calls. For AC 0~ 9, the network side sets the corresponding access control factor (Barring Factor) for each AC, and for AC 10~ 15, the network side sets a lbit identifier for each AC, and passes the system. The message is broadcast to the terminal. When the terminal corresponding to an AC accesses, if the AC of the terminal belongs to 0 to 9, the terminal generates a random number between 0 and 1. If the random number is smaller than the control factor corresponding to the AC, The terminal can access, if not, the terminal tries to access after delaying for a period of time; if the AC of the terminal belongs to 11~15, if the bit corresponding to the AC is 0, the terminal can access, otherwise, The terminal attempts to access after delaying for a period of time; if the AC of the terminal is 10, if the bit corresponding to the AC is 0, the terminal can access, otherwise, the terminal immediately attempts to access again. This mechanism can effectively cope with possible congestion in the current network and prevent the network from being overloaded. However, with the development of technology, the concept of Internet of Things has emerged. The narrow concept of the Internet of Things refers to the communication between machines and machines (Machine to Machine, M2M for short, 3rd Generation Partnership Project, 3rd Generation Partnership Project) In the meeting, M2M was also established as "Machine Type Communication" (MTC). The general concept of IoT includes communication between machines and machines, as well as traditional human-to-human communication (Human to Human). , referred to as H2H). After the introduction of the Internet of Things concept, the communication business was extended to all aspects of all walks of life. For example, smart home (including remote control of home appliances, remote monitoring of home security, etc.), intelligent traffic (traffic flow monitoring, accident monitoring, vehicle monitoring, etc.), smart metering (industrial instrument monitoring and remote control, remote meter reading) and many more. Therefore, the number of M2M terminals far exceeds that of H2H terminals. At the same time, the call arrival density is usually small compared to the H2H terminal, and the call arrival density of the M2M terminal is usually large. Therefore, after the concept of the Internet of Things is introduced, the main cause of network congestion is no longer the access of the H2H terminal, but the access of a large number of M2M terminals. In addition, after the concept of the Internet of Things is introduced, the type of the terminal is no longer only the H2H terminal, but also the M2M terminal. The current access control mechanism cannot effectively distinguish the two terminals. Moreover, different M2M applications may have different business models. The business model refers to a data transmission model when the user equipment and the network side exchange data, and the elements representing the business model include: data interaction periodicity, data interaction frequency, data size, Data interaction direction (refer to the above data, or the following line data, or the uplink and downlink traffic are similar). Take smart meters as an example. Some power companies require each smart meter to report meter reading data every 5 minutes. Some power companies require each smart meter to report meter reading data every hour. Some power companies even only require intelligence. The meter reports the meter reading data once a day, and the traffic of each meter reading data is small. This constitutes three different business models, which can be called high frequency periodic small data reporting, low frequency periodic small data reporting, Very low frequency periodic small data is reported. It is clear that these different business models have different pressures on the network, and the current mechanism is unable to distinguish these business models. In addition, different services may also have different Quality of Service (QoS) requirements. The QoS requirements related to access control include: Access delay tolerance, for example, some services are very sensitive to access delay (for example) Some services, such as fire alarm, security, medical monitoring, etc., have low sensitivity to access delays (such as meter reading), and the current mechanism cannot distinguish between these differences. Different services or user equipments also have different priorities. For example, financial, security, and medical-related services should have higher priority than ordinary services, and the current mechanisms cannot be distinguished. Therefore, after the M2M communication is widely applied, the current access control mechanism cannot flexibly perform access control operations according to the access object type, and cannot effectively cope with or avoid network congestion, thereby seriously affecting network communication quality. SUMMARY OF THE INVENTION A primary object of the present invention is to provide a method, a terminal, and a system for controlling terminal access, so as to solve the above-mentioned problem that the current access control mechanism cannot effectively cope with or avoid a large number of accesses of the M2M terminal, causing network congestion, thereby affecting communication quality. problem.

Step S104: The terminal performs access control according to the obtained access control information. The access control information in the embodiment of the present invention may be a flag bit or an indicator indicating whether the terminal is allowed to access, or may be a combination of an access control factor and an access control delay indicating that the terminal accesses proportionally. The specific implementation of the access control may be different according to the specific content of the access control information, and the specific manner is as follows: Method 1: The access control information used to indicate whether the terminal is allowed to access is a flag bit or an indicator; The access control information for performing access control includes: when the terminal determines, according to the access control information, that the terminal is allowed to access, the terminal initiates random access; and the terminal determines, according to the access control information, that the terminal is not allowed to access, The terminal cannot initiate random access. For example, when the terminal determines that the flag bit or the indicator is the first specified value (for example, 0), the terminal initiates random access; when the terminal determines that the flag bit or the indicator is the second specified value (for example, 1), the terminal cannot initiate random access. Access. In the case of mode 1, after the terminal cannot initiate random access, the foregoing method includes: the terminal intercepts a system message or a paging message from the network side, and acquires the next access control information from the system message or the paging message, according to the acquired An access control message is used for access control.

The length of the specific delay time can be adjusted as needed, or can be implemented by referring to the existing formula in the related art. The terminal in this embodiment adopts the corresponding access control measures according to the type of the access control object to which the terminal belongs, and performs the access control more flexibly and accurately, and solves the problem that the current access control mechanism cannot effectively cope with or avoid the M2M terminal accessing a large amount. The resulting network congestion, which affects the quality of communication, effectively protects the network and ensures communication quality. Embodiment 2 This embodiment provides a method for controlling terminal access, which is implemented on an LTE (Long-Term Evolution) system as an example. The access control operation is performed before the terminal initiates the random access. As shown in FIG. 3, the main steps of the method are as follows: Step S300: The network side sends the access control object type to the terminal, and the access control object type corresponds to Access control information. The network side may send the foregoing information by using a system message or a paging message, that is, the access control object type and the access control information corresponding to the access control object type. At this time, the terminal acquires the foregoing by listening to the system message or the paging message. information. Step S302: The terminal receives the access control object type from the network side, and the access control information corresponding to the access control object type, according to the type of the access control object to which the network belongs, and according to the access control object type sent by the network side. Access control information, obtaining access control information corresponding to the terminal, where the access control information includes an access control factor (ac-BarringFactor) and an access control delay (ac-BarringTime), or a flag bit, an indicator , for example, a bit. Step S304, the terminal performs an access control operation according to the access control information, and the specific control is as follows: The access control information is a flag bit or an indicator, for example, a bit: if the bit is "0", it indicates that the terminal can initiate a random connection. If the bit is "1", it means that the terminal cannot initiate random access. The access control information is an access control factor (ac-BarringFactor) and an access control delay (ac-BarringTime): the terminal generates a random number, and compares the random number with an access control factor, if the random number is less than the access The control factor indicates that the terminal can initiate random access. Otherwise, it indicates that the terminal cannot initiate random access. If the terminal is unable to initiate random access, the terminal generates a delay time according to the access control delay. After the delay time is reached, the terminal performs access control again. For example, the terminal generates a random number (rand), and according to the formula : (0.7+ 0.6 * rand) * ac-BarringTime generates a delay time after which the access control operation is re-executed. The "type of access control object" in the present embodiment refers to one or a combination of the following types of information: terminal type information, terminal priority information, terminal group information, terminal PLMN information, service Priority information, service QoS information, or business model information. The terminal type information includes one or more of the following: H2H terminal, M2M terminal, and other types of terminals. The terminal priority information refers to the priority agreed with the network side in advance, or the priority of the subscribed terminal, including: the priority sequence number, or the priority identifier. The existing H2H terminal can be used as a priority. In addition to the priority, one or more priorities can be added. The added priority can be higher or lower than the existing H2H terminal priority, and the existing H2H can be used. The terminal is based on the priority and can be classified as follows:

1) Add a priority, including the following two forms:

H2H terminal, low priority terminal (relative to H2H terminal); Or, a high priority terminal (relative to an H2H terminal), an H2H terminal.

2) Add multiple priorities, including the following three forms:

A: H2H terminal, low priority level 1 terminal, low priority level 2 terminal, ..., low priority N level terminal (N is a positive integer); B: high priority level 1 terminal, high priority level 2 Terminal, ..., high priority M-level terminal (M is a positive integer), H2H terminal;

C: high priority level 1 terminal, high priority level 2 terminal, ..., high priority level M terminal, H2H terminal, low priority level 1 terminal, low priority level 2 terminal, ..., low priority Level N terminals (M, ^^ are positive integers); for example, the network side and the M2M terminal agree that the M2M terminal has lower priority than the H2H terminal, and there are two priority terminals in the network: H2H terminal, M2M terminal . The group information of the terminal refers to the identifier of the terminal group, and includes: a serial number or identifier of the terminal group (Group). For example, the group information of the terminal may directly use a Group-RNTI (Radio Network Temporary Identifier), or may use a sequence number pre-agreed with the network side, and the network side pre-establishes a one-to-one correspondence between the sequence number and the packet. The terminal PLMN information refers to the information of the PLMN where the terminal is located, including: the terminal at the HPLMN, the terminal not at the HPLMN, the terminal not at the HPLMN or the equivalent PLMN, and the PLMN not in the HPLMN or the PLMN list in the (U)SIM Terminal. The service priority information refers to the priority agreed with the network side in advance, or the priority of the contracted service, including: priority sequence number, or priority identifier. In the existing protocol, the access control includes the types of services: Emergency (the terminal initiates an emergency call), MO-Signalling (the terminal initiates the signaling call), and MO-Data (the terminal initiates the data type call). In addition, this embodiment can also introduce a new service priority (the following "H2H service" refers to the type of service already included in the existing protocol), for example:

1) Add a priority, including the following two forms: H2H service, low priority service (relative to H2H service); or high priority service (relative to H2H terminal), H2H service.

2) Add multiple priorities, including the following three forms: A: H2H service, low priority level 1 service, low priority level 2 service, ..., low priority level N service (N is a positive integer);

B: high priority level 1 service, high priority level 2 service, ..., high priority level M service (M is a positive integer), H2H service; C: high priority level 1 service, high priority level 2 Service, ..., high priority M-class service, H2H service, low priority level 1 service, low priority level 2 service, ..., low priority level N service (M, N are positive integers); For example, for the meter type MTC (Machine Type Communication) service, its main function is to report the meter parameters, and the service priority is low. For the financial data transmission type MTC service, its main function is to transmit time-time financial data, and service priority. The level is higher than that of the meter type service. For the alarm type MTC service, the role is to perform alarms and the service priority is higher. Therefore, the priority of these three types of services is as follows: Alarm-like MTC service (high-priority service), financial data transmission-type MTC service (H2H service), and meter-type MTC service (low-priority service). The service QoS information includes a combination of one or more of the following requirements: access delay tolerance, guaranteed traffic, and allowed bit error rate. For example, the access delay can be set as follows: Two levels: sensitive to access delay and insensitive to access delay; multi-level: high access delay sensitivity, access delay sensitivity, and access delay sensitivity Low; can also be a combination of multiple QoS requirements, such as: high access delay sensitivity + low guaranteed traffic + low error rate requirements; or, access delay sensitivity + high guaranteed traffic + low error rate requirements The QoS can also be divided into more detailed levels. The service model information in this embodiment refers to a data communication model of a service, and includes a combination of one or more of the following features: data interaction periodicity (whether periodic data interaction), data interaction frequency, data volume size, Data interaction direction (refer to the above data, or the following line data, or the uplink and downlink traffic are similar). For example: information including only one feature: small data service model, or high-frequency business model, or periodic business model; information including multiple characteristics: periodic small data service model, low-frequency periodic small data reporting, Very low frequency periodic small data reporting, extremely high frequency periodic small data interaction model, medium frequency aperiodic big data downlink model. The correspondence between the specific service type and the service model is pre-agreed or contracted by the network side and the user equipment. The type of the access control object may be in various forms, that is, the type of the access control object may be one or more of the above types, or a combination of multiple types. For example: Combine the terminal priority information (taking two priorities as an example) with the PLMN information of the terminal, as shown in Table 1: Table 1

The terminal in this embodiment adopts corresponding access control measures according to the type of the access control object to which the terminal belongs, and performs access control more flexibly and accurately, thereby solving the problem that the current access control mechanism cannot effectively cope or avoid
