Description

Technical Field

[0001] Embodiments of the present invention relate to communication technologies, and in particular, to a method, apparatus, and device for transmitting activation type system information. Background Art

[0002] Mobile communication has profoundly changed people's lives, but the pursuit of higher performance mobile communication has never stopped. To cope with the future explosive growth of mobile data traffic, a large number of device connections, and emerging new services and application scenarios, the fifth-generation mobile communication (5G) system will emerge as the times require. As an important part of 5G, the Internet of Things (IoT) has a rapid growth in market demand. Currently, the 3rd Generation Partnership Project (3GPP) standard is researching to carry IoT (Internet of Things) services based on cellular networks by designing a new air interface and making full use of the characteristics of narrowband technology. This type of IoT is called NB-IoT. Compared with traditional cellular networks, the services and terminal devices of the NB-IoT network have the following characteristics: low data rate, long cycle, massive connection, low cost, and low power consumption, etc.

[0003] The NB-IoT network re-designs the system solution to meet the above requirements and characteristics of its own network, services, and terminals. In NB-IoT, due to the requirement of low cost, a new access control mechanism is introduced, and the access control parameters are placed in an independent System Information Block (SIB). Figure 1 For the access control schematic diagram of NB-IoT, as Figure 1 shown, the system messages include: Master Information Block (MIB), which includes the most important system parameters of the system, SIB1 that carries cell access control information and scheduling information of other system information blocks, and other SIBs such as SIB2 for radio resource configuration and newly added SIB_AC for access control. When the network is lightly loaded and access control is not performed, the access control (AC) resources will not be scheduled, and SIB_AC will not be sent. When the network is heavily loaded and access control is required, the access control (AC) resources will be scheduled, and SIB_AC needs to be sent. Thus, when the AC function is started and closed, since the scheduling information corresponding to it in SIB1 will also change accordingly, the user equipment (UE) always needs to read SIB1 to obtain updated scheduling information when the access control function is started and closed.

[0004] However, in NB-IoT, due to the system bandwidth that supports coverage enhancement features and narrow bands, the transmission time of the SIB1 message is relatively long, which will cause the UE to continuously detect and receive, increasing the power consumption of the UE. Summary of the Invention

[0005] Embodiments of the present invention provide a method, device, and equipment for transmitting activation class system information, which are used to solve the problem that in NB-IoT, due to the system bandwidth that supports coverage enhancement features and narrow bands, the transmission time of the SIB1 message is relatively long, which will cause the UE to continuously detect and receive, increasing the power consumption of the UE.

[0006] The first aspect of the present invention provides a method for transmitting activation class system information, including:

[0007] The UE receives a first system message sent by the base station; the first system message includes activation indication information and a change indication label; the activation indication information is used to indicate whether the function indicated in the activation class system message is activated; the change indication label is used to indicate whether the scheduling information of the activation class system message has changed;

[0008] The UE obtains first scheduling information of the activation class system message according to the activation indication information and the change indication label;

[0009] The UE reads the activation class system message according to the first scheduling information.

[0010] In this solution, the UE determines whether to obtain the first scheduling information from the local or from the system message broadcast by the base station according to the activation indication information and the change indication label in the first system message. After obtaining the first scheduling information, the UE reads the activation class system message at the position corresponding to the first scheduling information and completes the access to the service according to the indication in the activation class system message.

[0011] Combined with the first aspect, in the first possible implementation manner of the first aspect, the UE obtains the first scheduling information of the activation class system message according to the activation indication information and the change indication label, including:

[0012] The UE detects whether the scheduling information of the activation class system message is saved locally;

[0013] If the scheduling information of the activation class system message is saved locally, the UE determines whether the function indicated in the activation class system message is activated according to the activation indication information;

[0014] If the function indicated in the activation class system message is activated, the UE determines whether the scheduling information of the activation class system message has changed according to the change indication label;

[0015] If the scheduling information of the activation class system message does not change, use the locally stored scheduling information of the activation class system message as the first scheduling information.

[0016] In this solution, the UE first determines whether the scheduling information of the activation class system message is stored locally. If the scheduling information is saved locally, when the activation indication information indicates that the function of the activation class system message is activated, determine whether the scheduling information of the activation class system message has changed according to the change indication label. If not, use the locally stored scheduling information as the first scheduling information and receive the activation class system message on the resources indicated by this first scheduling information.

[0017] In this solution, if the scheduling information of the activation class system message is not saved locally, the UE receives the second system message sent by the base station; the second system message includes the first scheduling information of the activation class system message and the scheduling information of the regular class system message.

[0018] Optionally, if the scheduling information of the activation class system message is not saved locally and the function indicated in the activation class system message is activated, the UE receives the second system message sent by the base station; the second system message includes the first scheduling information of the activation class system message and the scheduling information of the regular class system message.

[0019] Optionally, if the scheduling information of the activation class system message changes, the UE receives the second system message sent by the base station; the second system message includes the first scheduling information of the activation class system message and the scheduling information of the regular class system message.

[0020] The meaning of the above several solutions is that after receiving the first system message, if the scheduling information of the activation class system message is not saved locally, or the scheduling information of the activation class system message is not saved locally and the function indicated by the activation class system message is activated, or the scheduling information of the activation class system message changes, etc., or the scheduling information of the activation class system message changes and the function indicated by the activation class system message is activated, the UE also needs to obtain the scheduling information of the activation class system message by receiving the second system message broadcast by the base station.

[0021] Combined with the solution of any one of the above, the method further includes:

[0022] The UE updates the scheduling information of the activation class system message stored locally to the first scheduling information. The meaning of this solution is that after obtaining the first scheduling information of the activation class system message, it should be stored. If there is an original one locally, it is updated, that is, the original scheduling information is deleted and updated to the first scheduling information. If there is no original one locally, the first scheduling information can be directly stored.

[0023] In a specific implementation, if the change indication label is a label value, the UE determines whether the scheduling information of the activation class system message has changed according to the change indication label, including:

[0024] If the UE detects that the label value has changed, it determines that the scheduling information of the activation class system message has changed; otherwise, it determines that the scheduling information of the activation class system message has not changed.

[0025] Combined with any of the above solutions, the activation class system message includes an access control message. Taking the access control (AC) message as an example, combined with the background technology, the main idea of this solution is to introduce a bit in the MIB to indicate whether the access control mechanism is enabled. The MIB includes a change indication label used to indicate whether the scheduling information has changed. In any case, the base station includes the scheduling information of SIB_AC in the scheduling information of SIB1. When it is determined that the access control function is deactivated, the base station does not send SIB_AC. When it is determined that the access control function is activated, the base station sends SIB_AC. For the UE, it can determine whether to read the scheduling information of SIB_AC sent by the base station according to the change indication label and activation indication information in the MIB.

[0026] The second aspect of the present invention provides a method for transmitting activation class system information, including:

[0027] The base station generates a first system message; the first system message includes activation indication information and a change indication label; the activation indication information is used to indicate whether the function indicated in the activation class system message is activated; the change indication label is used to indicate whether the scheduling information of the activation class system message has changed;

[0028] The base station broadcasts the first system message so that the UE can obtain the first scheduling information of the activation class system message according to the activation indication information and the change indication label, and read the activation class system message according to the first scheduling information.

[0029] The base station broadcasts the first system message, and the UE determines whether to read the scheduling information of the active type system message sent by the base station or obtain the scheduling information of the active type system message from the UE locally according to the activation indication information and the change indication label therein, and then receives the active type system message at the resource position indicated by the scheduling information.

[0030] Further, the method further includes:

[0031] The base station generates a second system message; the second system message includes the scheduling information of the active type system message and the scheduling information of the regular type system message;

[0032] If the activation indication information indicates that the function indicated in the active type system message is activated, the base station broadcasts the second system message and the active type system message;

[0033] If the activation indication information indicates that the function indicated in the active type system message is not activated, the base station broadcasts the second system message.

[0034] In this solution, the base station generates a second system message including the scheduling information of the regular type system message and the scheduling information of the active type system message, but it is necessary to determine whether the function indicated by the active type system message is activated. If it is activated, the second system message and the active type system message need to be broadcast simultaneously. If it is not activated, only the second system message needs to be broadcast.

[0035] In any of the above solutions, the change indication label is a label value.

[0036] Specifically, the base station generates the first system message, including:

[0037] When the base station determines that the scheduling information of the active type system message to be sent changes, it changes the label value; or,

[0038] When the base station determines that the base station changes from never sending the scheduling information of the active type system message to sending the scheduling information of the active type system message, or from sending the scheduling information of the active type system message to not sending the scheduling information of the active type system message, it changes the label value;

[0039] Or,

[0040] When the base station determines that the base station changes from never sending the scheduling information of the active type system message to sending the scheduling information of the active type system message, or from sending the scheduling information of the active type system message to not sending the scheduling information of the active type system message, it does not change the label value.

[0041] The meaning of this solution is as follows: When the base station generates the first system message, it needs to determine the value of this tag. The specific determination methods are as follows: First, if the base station determines that the scheduling information of the previously sent activation class system message is different from the current scheduling information, that is, the scheduling information of the activation class system message itself has changed, at this time, the tag value needs to be changed, that is, to a value different from the previous value for the UE to determine. Second, if the base station determines that the scheduling information of this activation class system message was not sent last time but is sent this time, or the scheduling information of this activation class system message was sent last time but is not sent this time, then at this time, the tag value can be changed or not changed, depending on the implementation of the base station.

[0042] In a specific implementation manner, the activation class system message includes an access control message. For the specific implementation, refer to the description on the UE side.

[0100] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0101] Figure 2 This is a schematic diagram of the application scenario of the transmission method for the activation class system information of the present invention. The solution of the present invention can be applied to a wireless communication system with large network coverage and multiple connections, such as Figure 2As shown, for example, in a low-cost and low-power IoT communication system of a terminal, the application scenario or the wireless communication system may include multiple base stations. Within the coverage range of each base station, there may be multiple user devices such as refrigerators, washing machines, cars, televisions, computers, water meters, electricity meters, etc. These user devices communicate through a wireless network or a cellular network. The data packets generated by the services of this IoT communication system are small and not very sensitive to latency. It is possible to achieve a large-scale deployment of user terminal devices, which may include large-scale deployed smart water / electricity meters, smart home devices, smart wearable devices, etc. There may be a large number of such devices under one base station. However, such a network deployment requires lower power consumption of the user devices or terminal devices to ensure the ultra-long standby of the user devices, thereby saving labor costs. However, in the existing control mechanisms for service functions corresponding to some activation class system information, the method of obtaining activation class system information requires continuous reading of the updated scheduling information in SIB1, which will increase the power consumption of the user devices. Accordingly, a more energy-efficient transmission method for activation class system information is proposed.

[0102] In the following technical solution, according to the requirement of the timeliness of obtaining system message changes, the system messages are divided into two categories: One is the regular class of system messages. After the change of this class of system messages, the UE does not need to obtain them immediately and can wait until the boundary of the change cycle before the UE obtains them. The other category is the activation class of system messages that need to be obtained in a timely manner. After the change of this class of system messages, the UE can obtain the updated system messages at any time without a specific application of a change cycle.

[0103] Figure 3 It is a flowchart of the first embodiment of the transmission method for activation class system information of the present invention. As Figure 3 shown, on the basis of the application scenario shown in Figure 2 the execution subject of this solution is the UE. The specific steps of the transmission method for activation class system information include:

[0104] S101: The UE receives the first system message sent by the base station; the first system message includes activation indication information and a change indication tag.

[0105] In this embodiment, the user device, that is, the terminal device on the user side, receives the first system message broadcast by the base station. The first system message refers to the system message necessary for transmission. Among them, the activation indication information is used to indicate whether the function indicated in the activation class system message is activated; the change indication tag is used to indicate whether the scheduling information of the activation class system message has changed.

[0106] S102: The UE obtains the first scheduling information of the activation class system message according to the activation indication information and the change indication tag.

[0107] In this step, the UE does not receive all the messages broadcast by the base station, especially the scheduling information for the activation-type system messages. The UE makes a judgment based on the activation indication information and the change indication tag. If the scheduling information for the activation system message is stored locally and the change indication tag indicates that the scheduling information for the activation-type system message has not changed, then the UE can directly use the local scheduling information as the first scheduling information; if it is not stored locally, it will receive it from the messages broadcast by the base station.

[0108] S103: The UE reads the activation-type system message according to the first scheduling information.

[0109] In this step, after the UE obtains the first scheduling information, it needs to receive the activation-type system message on the resources (which can also be called positions) indicated by the first scheduling information.

[0110] The terminal uses the corresponding activation function according to the functions supported in the activation-type system message.

[0111] Taking access control as an example, when the terminal reads the message where the access control message is located, it decides whether to access the network according to the access control parameters included therein.

[0112] In the transmission method of the activation-type system information provided in this embodiment, by carrying the activation indication information and the change indication tag in the first system message broadcast by the base station, after the UE receives the first system message, according to the activation indication information and the change indication tag, it selects different ways to obtain the first scheduling information of the activation-type system message, and then reads the activation-type system message at the position corresponding to the first scheduling information, ensuring that the UE only needs to receive the scheduling information of the activation-type system message when the scheduling information changes, avoiding the UE continuously being in the detection and reception state, and effectively reducing the power consumption of the UE.

[0113] Based on the above embodiment, the specific implementation manner for the UE to obtain the first scheduling information is introduced in detail below.

[0114] Figure 4 This is the flowchart of the second embodiment of the transmission method of the activation-type system information of the present invention. As Figure 4 shown, based on the above embodiment, the specific implementation steps for the UE to obtain the first scheduling information of the activation-type system message in S102 according to the activation indication information and the change indication tag are as follows:

[0115] S201: The UE detects whether the scheduling information of the activation-type system message is stored locally.

[0116] In this step, after receiving the first system information, the UE first needs to detect whether the scheduling information of one or more corresponding active system messages is stored locally, that is, it needs to be stored every time it is obtained.

[0117] Optionally, if the UE detects that the scheduling information of the active system message is not saved locally, the UE receives the second system message sent by the base station; the second system message includes the first scheduling information of the active system message and the scheduling information of the regular system message. Its meaning is: after the UE does not save the scheduling information of the active system message locally, it needs to obtain it from the second system message broadcast by the base station, that is, read it from the scheduling information block.

[0118] S202: If the scheduling information of the active system message is saved locally, the UE determines whether the function indicated in the active system message is activated according to the activation indication information.

[0119] In this step, if the UE saves the scheduling information of the active system message, then the UE needs to detect whether the function indicated by the active system information is activated. If the function indicated by the active system information is activated, the scheduling information needs to be obtained.

[0120] S203: If the function indicated in the active system message is activated, the UE determines whether the scheduling information of the active system message has changed according to the change indication label.

[0121] In this step, if the UE determines that the function indicated in the active system message is activated and has determined that the scheduling information of the active system message is stored locally according to the above steps, it is necessary to further determine whether the scheduling information of the active system message has changed. In a specific implementation, the change indication label can be a label value, that is, a value is used to represent the change of the scheduling information. The specific method for determining whether the scheduling information has changed is: if the UE detects that the label value has changed, it is determined that the scheduling information of the active system message has changed; otherwise, it is determined that the scheduling information of the active system message has not changed. That is, it is detected whether the current label value is the same as the previously obtained label value. If they are the same, it is considered that the scheduling information of the active system message has not changed, otherwise it is considered that the scheduling information of the active system message has changed.

[0122] The above meaning refers to: if the change indication label itself has not changed, it is determined that the scheduling information of the active function has not changed; if the change indication label itself has changed, it is determined that the scheduling information of the active function has changed.

[0123] Optionally, the situation where it is determined that the scheduling information of the activation class system message has not changed includes at least the following two cases: First, if the change indication tag indicates no change and the second system message does not include the scheduling information of the activation class system message, the UE determines that the scheduling information of the activation class function has not changed; Second, if the change indication tag indicates no change and the second system message includes the scheduling information of the activation class system message, the UE determines that the scheduling information of the activation class function has not changed.

[0124] Optionally, during the above process, if the scheduling information of the activation class system message is not locally stored and the function indicated in the activation class system message is activated, the UE receives the second system message sent by the base station; the second system message includes the first scheduling information of the activation class system message and the scheduling information of the regular class system message.

[0125] That is, during this process, if it is found that the scheduling information of the activation class system message is not locally stored and the activation indication information indicates that the function indicated by the activation class system message is activated, at this time, in order to obtain the corresponding scheduling information of the activation class system message, it is necessary to read the corresponding scheduling information of the activation class system message from the second system message broadcast by the base station as the first scheduling information.

[0126] S204: If the scheduling information of the activation class system message has not changed, the scheduling information of the activation class system message stored locally is used as the first scheduling information.

[0127] The meaning of this step is: when it is determined that the activation class system message is locally stored, the function indicated in the activation class system message is activated, and the scheduling information of the activation class system message has not changed, in this case, there is no need to read the second system message broadcast by the base station, and the scheduling information stored locally can be directly used as the first scheduling information.

[0128] Optionally, if the scheduling information of the activation class system message changes, the UE receives the second system message sent by the base station; the second system message includes the first scheduling information of the activation class system message and the scheduling information of the regular class system message.

[0129] However, if it is determined through the tag value that the scheduling information of the activation class system message has changed, it is necessary to read and obtain the first scheduling information from the second system message.

[0130] Further, after obtaining the first scheduling information, the UE updates the scheduling information of the activation class system message stored locally to the first scheduling information. That is, if the scheduling information of the activation class system message changes, the originally saved scheduling information locally is deleted and updated to the new scheduling information; if there is no change, there is no need to update; in addition, if the scheduling information was not originally saved locally, it needs to be stored after obtaining the first scheduling information.

[0131] In the above process, in order to monitor the change of the tag value, the UE needs to save the corresponding tag value locally after each processing, so as to make a comparison during the next detection.

[0132] Optionally, the activation class system message includes an access control message.

[0133] In the transmission method of the activation class system information provided in this embodiment, the UE determines whether the function in the activation class system information is activated according to the activation indication information and the change indication tag in the first system message, and determines whether the scheduling information of the activation class system information has changed. When the scheduling information of the activation class system information is stored locally, the corresponding function is activated, and the scheduling information has not changed, there is no need to receive the scheduling information from the base station. Instead, the scheduling information stored locally is used as the first scheduling information of the activation class system information, and the corresponding activation class system information is read according to the first scheduling information to complete the subsequent service, reducing the time for the terminal to be in the detection and reception state and reducing the power consumption of the UE.

[0134] Figure 5 It is a flowchart of the third embodiment of the transmission method of the activation class system information of the present invention. As Figure 5 shown, in the scenario shown above Figure 2 if the execution subject of the solution is the base station, the specific implementation steps of the transmission method of the activation class system information are as follows:

[0135] S301: The base station generates a first system message; the first system message includes activation indication information and a change indication tag.

[0136] In this embodiment, the activation indication information is used to indicate whether the function indicated in the activation class system message is activated; the change indication tag is used to indicate whether the scheduling information of the activation class system message has changed.

[0137] S302: The base station broadcasts the first system message so that the user equipment UE can obtain the first scheduling information of the activation class system message according to the activation indication information and the change indication tag, and read the activation class system message according to the first scheduling information.

[0138] In this embodiment, the base station carries a change indication tag in the first system message for the UE to determine whether the scheduling information of the active system information has changed. If there is no change, and the function of the active system message is activated, and the UE has stored the scheduling information of the previous active system message, the UE can directly use this scheduling information as the first scheduling information to read the active system message. The UE does not need to read the second system message anymore.

[0139] For the base station side, whether or not the function in the above-mentioned active system message is activated, it is necessary to generate the second system message.

[0140] Further, the base station generates the second system message; the second system message includes the scheduling information corresponding to the active system message and the scheduling information of the regular system message;

[0141] If the activation indication information indicates that the function indicated in the active system message is activated, the base station broadcasts the second system message and the active system message;

[0142] If the activation indication information indicates that the function indicated in the active system message is not activated, the base station broadcasts the second system message.

[0143] The above-mentioned broadcast meaning of the second system message means that if the function in the active system message is activated, it is necessary to broadcast the second system message and the active system message. If the function in the active system message is not activated, only the second system message needs to be broadcast, and there is no need to broadcast the active system message.

[0144] In a specific implementation, the change indication tag is a tag value.

[0145] The base station generates the first system message, including:

[0146] When the base station determines that the scheduling information of the active system message to be sent has changed, it changes the tag value; or,

[0147] When the base station determines that the base station changes from never sending the scheduling information of the active system message to sending the scheduling information of the active system message, or from sending the scheduling information of the active system message to not sending the scheduling information of the active system message, it changes the tag value; or,

[0148] When the base station determines that the base station changes from never sending the scheduling information of the active system message to sending the scheduling information of the active system message, or from sending the scheduling information of the active system message to not sending the scheduling information of the active system message, it does not change the tag value.

[0149] The meaning of the above-mentioned medium tag value for the first system message, that is, the scheme for changing the change indication tag is as follows: If the base station determines that the scheduling information of the active system message scheduled this time is different from the scheduling information of the active system message last time, the tag value will be changed so that the UE can determine that the scheduling information has changed after receiving it. If the base station determines that the scheduling information of the active system message was not sent last time but is scheduled to be sent this time, or the scheduling information of the active system message was sent last time but not sent this time, that is, when the behavior of sending or not sending the scheduling information itself changes, the tag value can either be changed or not changed.

[0150] That is to say, if the base station sends the scheduling information of the active system message in the second system message, and if the scheduling information changes, the base station changes the change tag indication; or, if the change in whether the base station includes the scheduling information of the active system message in the second system message occurs, the base station changes the change tag indication; or, when the change in whether the base station includes the scheduling information of the active system message in the second system message occurs, the base station does not change the change tag indication. The change in whether the base station includes the scheduling information of the active system message in the second system message specifically includes: the second system message of the base station changes from previously including the scheduling information of the active system message to currently not including the scheduling information of the active system message; or,

[0151] the second system message of the base station changes from previously not including the scheduling information of the active system message to currently including the scheduling information of the active system message.

[0152] Optionally, the active system message includes an access control message.

[0153] Based on Figure 2 the application scenario shown below, for the NB-IoT system, taking the access control message as an example, the transmission method of the active system information of the present invention (equivalent to the access control method in this solution) will be described in detail: The network elements set in this solution are the base station and the user equipment, and the main idea of this solution is:

[0154] 1. Introduce a bit (i.e., the above-mentioned activation indication information) in the Master Information Block (MIB) to indicate whether the access control mechanism of NB-IoT is enabled. In addition, there is a value tag (i.e., the change indication tag) in the MIB to indicate the change indication of multiple SIBs that affect the change of the value tag in addition to the MIB;

[0155] 2. Whether the NB-IoT access control function is started or not, the scheduling information of SIB_AC is included in the scheduling information of SIB1. The change of this scheduling information will affect the value tag in the MIB, that is, the base station always schedules the SIB_AC system information.

[0156] Specifically, in the case where the access control function is deactivated (AC = OFF), the SIB_AC system message is not sent, and the radio resources corresponding to the SIB_AC system message can be used for other data transmissions. In the case where the access control function is activated (AC = ON), the SIB_AC system message is sent.

[0157] 3. For the UE, the UE determines whether to read the scheduling information of the SIB_AC system message and the SIB_AC system message according to the value tag in the MIB and the bit indicating whether the access control in the MIB is activated.

[0158] Optionally, another method is: Whether SIB_AC is broadcast or not is the same as that of the existing LTE, which will cause the scheduling information of SIB1 to change, but the value tag in the MIB may not change. The eNB judges whether it is necessary to update the value tag according to the broadcast period, occupied resources, etc. of SIB_AC. If these information do not change, and only SIB_AC starts and ends broadcasting, the value tag can remain unchanged.

[0159] In the solution of the present invention, according to the requirement of the timeliness of obtaining system message changes, the system messages are divided into two categories: one is the regular system message. After the change of this type of system message, the UE does not need to obtain it immediately and can wait until the boundary of the change cycle before the UE obtains it. The other is the activation type system message that needs to be obtained in a timely manner. After the change of this type of system message, the UE can obtain the updated system message at any time, and there is no application of a specific change cycle.

[0160] For conventional system messages, whether they change or not can be indicated by the value tag. By comparing the different values of the value tag, it can be determined whether the system message has changed. Each value tag represents a version of the conventional system message. When the value tag changes, it means that some conventional system messages have changed. The value tag is used to indicate the change situation of the system message block after the system message where it is located. For example, if the value tag is located in the MIB, the value tag is used to indicate the changes of all conventional SIBs except the MIB, including SIB1, SIB2, SIB3, 4, 5, etc. (wherein, the scheduling information carrying the cell access control information and other system information blocks is represented as SIB1, and the one for radio resource configuration is represented as SIB2, the newly added cell access control is represented as SIB_AC, and the cell selection and reselection configuration is represented as SIB3, 4, 5).

[0161] For system messages that need to be obtained in a timely manner, there are also other possible system messages that need to be obtained in a timely manner, which will not be listed one by one. For example, for SIB_AC where the access control parameters are located, when the access control parameters change, the UE can obtain them in a timely manner without waiting until the change cycle boundary to obtain them.

[0162] In addition, triggered from the perspective of saving terminal power consumption, an indication is introduced in the MIB to indicate whether the access control function is started or enabled, or whether other system message blocks that need to be obtained in a timely manner are enabled. Here, taking the access control message block as an example, the sending and obtaining methods of the scheduling information of the system message block that needs to be obtained in a timely manner are described. The obtaining method of the scheduling mechanism of other system message blocks that need to be obtained in a timely manner is the same as that of the access control message block scheduling information, and will not be elaborated one by one.

[0163] Combined with the main idea of the above-described solution, Figure 6 For the NB-IoT access control schematic diagram provided by the present invention, as Figure 6 shown, first, the base station sends an indication of the start of access control in the MIB (equivalent to the activation indication information, which is used to indicate whether the access control is activated in this solution).

[0164] The base station schedules the access control and sends the scheduling information of SIB_AC (access control message block) in the scheduling information of SIB1.

[0165] On the UE side, when the UE reads the system message, the UE first reads the value tag (equivalent to the above change indication tag) and the access control start indication in the MIB. If it indicates that the access control function is started, the UE checks whether there is SIB1 that saves the scheduling information of the access control parameters locally.

[0166] If the UE detects that it is not saved locally, the UE reads the scheduling information of the access control parameter SIB_AC from the SIB1 sent by the base station, and then reads the SIB_AC where the access control parameter is located from the resource position indicated in the obtained scheduling information. That is, when the scheduling information of SIB_AC is not saved locally, the UE needs to read the scheduling information of SIB_AC in the SIB1 broadcast by the base station and receive the SIB_AC where the access control parameter is located on the corresponding resource.

[0167] If the UE detects that it is saved locally, the UE compares the current value tag with the previously saved value tag. If the value tag values are the same, the UE uses the previously saved scheduling information of the access control parameter SIB_AC to read the SIB_AC where the access parameter is located, without needing to read the SIB1 where the scheduling information of the access control parameter broadcast by the base station is located. If the value tag values are different, the UE reads the updated scheduling information of the access control parameter SIB_AC in the SIB1, then saves or updates the scheduling information of the access control parameter locally, and reads the SIB_AC of the access control parameter transmitted at the resource position indicated by the scheduling information.

[0168] In the above solution, when the UE reads the system message, the UE first reads the value tag and the access control start indication in the MIB. If the access control start indication indicates that the access control function is turned off, that is, the access control function is not activated, the UE can read the scheduling information of the access control parameter in the SIB1 and save it locally in the UE; it can also directly not read the scheduling information in the SIB1.

[0169] The above solution can ensure that the user equipment only needs to obtain the scheduling information of the access control parameter when the scheduling information related to the access control parameter changes and the access control function is started, achieving the effect of saving the power consumption of the UE. Compared with the existing technology where the user equipment needs to always serve the SIB to obtain the scheduling information of the access control parameter, the user equipment in this solution does not need to always read the SIB1 to obtain the updated scheduling parameter corresponding to the access control parameter when the access control function is started and turned off, achieving the purpose of saving power consumption.

[0170] In addition, based on the above solution, another implementation is provided:

[0171] When the UE reads the system information, the UE first reads the value tag and the access control start indication in the MIB. If the indication indicates that the access control function is started, the UE checks whether there is SIB1 that stores the scheduling information of the access control parameters. If the UE does not have the stored SIB1 locally, the UE reads SIB1 to obtain the scheduling information of the access control parameters, and then obtains the SIB_AC where the access control parameters at the resource location indicated in the scheduling information are located. If the UE has the stored scheduling information, the UE compares the current value tag with the previously stored value tag. If the value tag values are the same, the UE uses the scheduling information corresponding to the previously stored access control parameters to read the SIB_AC where the access parameters are located, without the need to read SIB1 where the access control parameters are located. If the value tag values are different, the UE reads the scheduling information of the updated access control parameters in SIB1, and then updates the SIB_AC where the access control parameters are located by reading the updated scheduling information.

[0172] When the UE reads the system information, the UE first reads the Value tag and the access control start indication in the MIB. If the access control start indication indicates that the access control function is turned off, the UE stores the scheduling information of the access control parameters in SIB1.

[0173] Different from the foregoing solution, if SIB1 changes for other reasons, the UE may reread SIB1 according to the valueTag. However, for the scheduling information of SIB_AC, if the new SIB1 does not contain it, it is considered that the original SIB_AC scheduling information is still retained. That is, when the new SIB1 does not include the scheduling information of the access control parameters, the locally stored scheduling information is still used to read the access control parameters at the corresponding location.

[0174] Optionally, there is another possible processing method. When the UE detects that there is no stored scheduling information of SIB_AC locally, the UE reads SIB1 to obtain the scheduling information of SIB_AC later for storage. Regardless of whether the access control function is activated at this time, the scheduling information of SIB_AC in SIB1 can be read and stored, so that in the subsequent process, if it is determined that the scheduling information has not changed, the locally stored scheduling information can be directly used without having to read SIB1 again, thereby achieving the purpose of energy saving.
