In addition, in the embodiment of the present disclosure, the communication system may be Long Term Evolution (LTE).

First embodiment

Referring to FIG. 2, FIG. 2 is a flowchart of a method for transmitting a system information block according to an embodiment of the present disclosure. As shown in FIG. 2, the method includes the following steps:

Step 201: The terminal receives system information sent by the network side device, where the system information includes necessary system information of the terminal accessing the communication system, and configuration information of other system information blocks, where the other system information blocks are the communication system. A system information block other than the necessary system information.

In the embodiment of the present disclosure, the system information may be periodically broadcast by the network side device. Of course, aperiodic broadcast may also be used. The necessary system information may be understood as system information necessary for the terminal to access the communication system, wherein the access communication system may also be understood as an access network, that is, the necessary system information may be system information necessary for the terminal to access the network, for example, The system information necessary for accessing the network, such as the bandwidth information system information and the frequency point system information, is not limited in this embodiment of the present disclosure.

In the embodiment of the present disclosure, the above-mentioned necessary system information may be referred to as minimum system information (minimum SI). That is, in the embodiment of the present disclosure, the system information of the communication system is divided into two types, one is minimum system information (minimum SI), and the other is the other system information block (other SIB (OSIB)). It should be noted that, in the embodiment of the present disclosure, other system information blocks may be system information blocks other than the above-mentioned necessary system information, that is, not necessary system information is referred to as other system information blocks, for example, represented by OSIB. It should be noted that, in the embodiment of the present disclosure, any system information block in other system information blocks may be represented by OSIB.

The foregoing configuration information may be information required when the terminal acquires other system information blocks, for example, some description information of other system information blocks, so that the terminal knows what content of the other system information blocks includes. It should be noted that, in the embodiment of the present disclosure, the configuration information is not limited, and the configuration information may be any that allows the terminal to identify the other system information blocks. After the terminal identifies the other system information blocks, it may determine whether An acquisition request needs to be initiated to the network side device.

Step 202: The terminal stores the storage of other system information blocks based on the configuration information and the terminal. And determining, by the network side device, the target system information block required by the terminal, and if yes, performing step 203, where the target system information block is one or more of the other system information blocks. System information block.

The process may be ended when it is determined that the target system information block required by the terminal is not required to be obtained from the network side device. The figure is illustrated by the end process. Of course, when the target system information block is not acquired, the terminal may continue to use other stored system information blocks.

The storage condition may be that the terminal does not store other system information blocks, or the storage condition may be that the terminal stores all or part of the system information blocks in other system information blocks.

In step 202, the foregoing determining may be based on the configuration information and the storage condition to identify a target system information block included in the other system information block including the terminal. For example, the target system information block required by the terminal is OSIB1, and the foregoing configuration information determines that the other system information blocks include OSIB1, and the terminal does not store OSIB1, so that the terminal can determine that the OSIB1 needs to be acquired from the network side device. Or the foregoing determining may be that the system information block stored by the terminal is not the latest system information block in the communication system based on the configuration information and the storage condition. For example, the terminal stores the OSIB 5, but the version number of the OSIB 5 is 1, and the version number of the OSIB 5 in the other system information block is determined to be 2 by the configuration information, so that the terminal can determine that the OSIB 5 needs to be acquired from the network side device.

The target system information block is one or more system information blocks in the other system information blocks. The target system information may be one or more other system information blocks. Therefore, in the embodiments of the present disclosure, other system information blocks are referred to as long as they are not necessary.

Step 203: The terminal sends an acquisition request for acquiring the target system block to the network side device.

The foregoing acquisition request may be understood as a request message for requesting the network side device to acquire the target system information block. For example, the foregoing acquisition request carries the identifier of the target system block, so that the network side device identifies the target system information block required by the terminal, and then sends the target system information block to the terminal according to the acquisition request.

Step 204: The terminal receives the target system information block that is sent by the network side device according to the acquiring request.

The terminal may be a target system information block that is received by the network side device, or may be a target system information block that is sent by the network side device to the terminal separately.

Through the above steps, the terminal and the network side device can transmit the system information block according to the needs of the terminal, so as to reduce the request of the terminal to initiate unnecessary other system information blocks, thereby better reducing the signaling overhead of the air interface and reducing the power consumption of the terminal. It also reduces the power consumption of network-side devices.

In the system information block transmission method provided by the embodiment of the present disclosure, the terminal receives system information sent by the network side device, where the system information includes necessary system information of the terminal accessing the communication system, and configuration information of other system information blocks, The other system information block is a system information block in the communication system except the necessary system information; the terminal determines whether it needs to be based on the configuration information and the storage condition of the terminal storing other system information blocks. The network side device acquires a target system information block required by the terminal, where the target system information block is one or more system information blocks in the other system information block; if the terminal needs to go to the network The side device acquires a target system information block required by the terminal, and the terminal sends an acquisition request for acquiring the target system block to the network side device; the terminal receives the location that the network side device sends according to the acquisition request. The target system information block. Since the terminal can accurately and efficiently initiate the request for acquiring the system information block according to the storage condition of the terminal storing other system information blocks and the system information block configuration information of the network, the system information block transmitted by the network side device is only required by the terminal. There is no need to transmit information blocks that are not needed by the terminal, thereby reducing signaling overhead, saving radio resources, and reducing power consumption of the terminal and network side devices.

Second embodiment

Referring to FIG. 3, FIG. 3 is a flowchart of a method for transmitting a system information block according to an embodiment of the present disclosure. As shown in FIG. 3, the method includes the following steps:

Step 301: The terminal receives system information sent by the network side device, where the system information includes necessary system information that the terminal accesses the communication system, and configuration information of other system information blocks, where the other system information blocks are the communication system. a system information block in addition to the necessary system information, the system information further includes a flag bit, where the flag bit is used to indicate configuration information of other system information blocks in the system information and the network side device Whether the configuration information of other system information blocks in the system information sent at one time is the same.

Wherein, the above flag bit can be represented by 1 bit (bit), and is used to indicate the currently transmitted system. Whether the configuration information of other system information blocks in the information is the same as the configuration information of other system information blocks in the last transmitted system information, such as 1 indicates different, and 0 indicates the same.

Optionally, the foregoing configuration information includes one or more of the following: an identity identifier (ID flag) of each system information block in the other system information block; and a version number identifier of each system information block in the other system information block, The version number flag is used to indicate the content of the corresponding system information block; the availability flag of each system information block in the other system information block, the availability flag is used to indicate whether the network side device supports the corresponding system information block. The scheduling information of each system information block in the other system information block.

In the embodiment of the present disclosure, each system information block has a flag for identifying a system information block, and different system information blocks have different flags for distinguishing between the terminal and the network side device. For example, the OSIB ID flag, due to the presence of multiple OSIBs, may require ID to identify each different OSIB. Currently, LTE includes 20 SIB information blocks, so all LTE SIBs can be identified by 4 bits. Considering the scalability of future communication systems (eg, 5G systems), more bits can be used to identify the OSIB. For example, a total of 64 OSIBs (other SIBs) can be identified by 6 bits. According to the actual situation of the number of OSIBs of the 5G system, the remaining flag bits are reserved. For example, with 000001, OSIB1,000010 represents OSIB2, and so on, until the last OSIB is identified, and the extra flag bits are reserved. It should be noted that, in the embodiment of the present disclosure, the foregoing configuration information may include only the identity identifier of each system information block. For example, if the terminal recognizes that a certain system information block is not stored by the terminal, the terminal may initiate the acquisition process of the system information block.

It should be noted that, in the embodiment of the present disclosure, the OSIB can be understood as any one of the other system information blocks.

The version number flag of the system information block can be understood as indicating the content carried by each OSIB. That is, the version number flag of the system information block can be understood as the indication information of the content of the system information block, and the terminal and the network side device can determine the content of the system information block by using the indication information. The version number flag enables the terminal to accurately obtain the content of the system information block required by the terminal, so that the content of the system information block acquired by the terminal is not wasted by the terminal.

The availability flag of the system information block can determine whether the network side device supports the corresponding system information block. For example, the 1 bit flag bit can be used, where 1 indicates that the base station supports the function represented by the OSIB, and 0 indicates that the base station does not support the function represented by the OSIB. .

The scheduling information may be a time-frequency resource indicating that the network side device transmits each system information block in the other system information block, a time-frequency resource broadcasted by the network-side device, or a time-frequency resource in which the network-side device transmits the dedicated signaling of the system information block. Wait. And one scheduling information may correspond to one or more system information blocks, that is, one or more system information blocks may be transmitted by using the same time-frequency resource.

Optionally, the foregoing scheduling information is used to indicate a time-frequency resource and a sending period of the broadcast transmission of the corresponding system information block.

The network side device of each system information block in the other system information blocks may be broadcasted, and the terminal is notified by the foregoing scheduling information, so that the terminal can accurately receive the required system information block. For example, the above scheduling information may represent such information, frequency mapping, time resource, period, and the like in detailed fields.

Optionally, at least one version number identifier is included in the version number flag included in the configuration information, where the content version of the corresponding system information block is in the plurality of content versions predefined by the network side device and the terminal. a content version; or at least one special version number flag is included in the version number flag included in the configuration information, where the special version number flag is used to indicate that the content version of the corresponding system information block is the network side device and the A content version other than a plurality of content versions predefined by the terminal.

All or part of the version number flag in the configuration information may be a content version indicating that the content version of the corresponding system information block is a content version of the plurality of content versions predefined by the network side device and the terminal. Similarly, the above configuration information may be that all or part of the version number is marked as the above special version number flag. Since the configuration information may include content indicating that the network side device and the terminal pre-agreed, the content of each system information block may be notified only by the version number flag, thereby reducing signaling overhead. For example, for each OSIB, 8 versions of the OSIB can be represented by 3 bits, and each version number corresponds to a different content in the OSIB. The signaling overhead can be further reduced by the above special version number flag. For example, the version number owned by each OSIB does not exhaust all the different contents of the OSIB, so a special version number is set for each OSIB, the special The version number indicates that the specific content of the OSIB using the version number is not predefined. That is, for an OSIB using a special version number, the UE does not know the specific content of the OSIB of the special version number. For example, a special version can be represented by 000.

According to the above, the configuration information carried in the system information sent by the network side device may be Use the following table 1 to show:

Table 1

It should be noted that the network side device may maintain information similar to the above Table 1 on the network side device end according to actual conditions, and the foregoing system information is sent to the terminal. The network side device and the terminal have a consistent understanding of the information listed above. The network side device only provides the configuration information of each OSIB in the system information, and does not include the specific content of each OSIB. Therefore, when the terminal needs to obtain the specific content of an OSIB, the terminal completes the OSIB acquisition required by the terminal according to the flag bit information in the system information and the configuration information of each OSIB.

Step 302: If the flag indicates that the configuration information of other system information blocks in the system information is the same as the configuration information of other system information blocks in the system information sent by the network side device, the terminal is stored according to the The other system information block and the terminal's requirement for other system information blocks determine whether the configuration information needs to be acquired. If yes, step 303 is performed, and if not, the process may be ended.

In the step 302, when the other system information blocks stored in the terminal meet the requirements of the terminal for other system information blocks, it is determined that the configuration information is not required to be obtained, so that the step can be ignored. The configuration information about the OSIB in the system information received in step 301 is used to save energy consumption of the terminal. For example, the terminal needs OSIB6, and the OSIB6 exists in other system information blocks stored by the terminal, or the content of the OSIB7 stored by the terminal can meet the requirements of the terminal for the OSIB7 and the like. In step 302, when the other system information blocks stored in the terminal cannot meet the requirements of the terminal for other system information blocks, it is determined that the configuration information needs to be acquired. For example, the terminal needs OSIB6, but OSIB6 does not exist in other system information blocks stored in the terminal, or the content of OSIB7 stored in the terminal cannot meet the requirements of the terminal for OSIB7, or the version number of OSIB7 stored by the terminal has expired or the storage time has exceeded Set the duration and so on.

It should be noted that step 302 in the second embodiment, and the flag bits in the system information are all optional. That is, it is also possible that the flag information is not included in the system information in step 301. For example, the terminal may default that the configuration information in step 301 is different from the configuration information sent by the network side device last time. Alternatively, if the configuration information in the foregoing step 301 is different from the configuration information that is sent by the network device, the step 303 may be directly executed without performing step 302.

Step 303: The terminal determines, according to the configuration information and the storage condition of the other system information block that the terminal stores, whether to acquire the target system information block required by the terminal from the network side device, and if yes, execute step 304. Otherwise, the process may be ended, wherein the target system information block is one or more system information blocks in the other system information blocks.

The step 303 may be performed when the configuration information indicating that the other system information blocks in the system information are different from the configuration information of other system information blocks in the system information that is sent by the network side device. .

Optionally, the storage situation includes that the terminal stores other system information blocks, and the terminal determines, according to the configuration information and the storage status of the other system information blocks, whether the terminal needs to acquire the network side device. The step of the target system information block required by the terminal includes: if the terminal determines that the configuration information needs to be acquired and/or if the flag bit indicates configuration information of other system information blocks in the system information and the network The configuration information of the other system information blocks in the system information sent by the side device is different, and the terminal acquires the configuration information; the terminal determines, according to the configuration information, other system information blocks and devices stored by the terminal. Whether there is a target system information block whose content is inconsistent in other system information blocks indicated by the configuration information; if there is a target system information block whose content is inconsistent, the terminal determines whether based on the feature information of the terminal The target system information block needs to be obtained from the network side device.

In this step, the terminal determines that the target system information block needs to obtain the configuration information and performs the foregoing determination, so that the terminal can prevent the terminal from acquiring the configuration information and performing the foregoing determination operation without the target system information block, so as to save the terminal. The effect of consumption. In the same manner, when the configuration information in the system information received by the flag indicating step 301 is different from the configuration information in the system information sent by the network device, the configuration information is obtained and the foregoing determination is performed, so that step 301 can be avoided. When the configuration information in the system information is the same as the configuration information in the last transmitted system information, the same configuration information is obtained again to achieve the effect of saving terminal energy consumption.

The target system information block in which the content is inconsistent may be that the content of the target system information block stored by the terminal does not match the content of the target system information block indicated by the configuration information. For example, after the terminal stores the target system information block, the network side device or the network updates or modifies the content of the target system information block, so that the target system information block stored by the terminal is not the latest content. For example, the OSIB8 stored in the terminal, wherein the OSIB8 is the content of the first version, but the network or network side device updates the OSIB8, and the updated OSIB8 is the content of the second version.

And determining, according to the feature information of the terminal, whether the target system information block needs to be acquired to the network side device, after determining that the target system information block with content inconsistency is present, the terminal determines, according to the feature information, whether the Target system information block. For example, the target system information block is the multicast broadcast service system information, but the terminal determines that the target system information block does not need to be acquired to the network side device when it is determined that the multicast broadcast service is not required according to the feature information. If the terminal determines that the multicast broadcast service needs to be performed according to the feature information, it may determine that the target system information block needs to be acquired to the network side device. In addition, if there are multiple system information blocks in the target system information block in which the content is inconsistent, the terminal may selectively send an acquisition request to the network side device according to the requirement thereof to request the system information block required by the terminal.

It should be noted that, in the above embodiment, when the step 302 is not performed, and the system information in the step 301 does not include the flag bit, the terminal stores the storage of other system information blocks based on the configuration information and the terminal. The step of determining whether the target system information block required by the terminal needs to be obtained from the network side device may include: the terminal acquiring the configuration information; the terminal determining, according to the configuration information, the terminal storage Other system information blocks and the matching Whether there is a target system information block in which the content is inconsistent in the other system information blocks indicated by the information; if there is a target system information block in which the content is inconsistent, the terminal determines whether it is necessary to the network side device based on the feature information of the terminal. Obtaining the target system information block. That is, the terminal can directly obtain the foregoing configuration information, and perform corresponding judgments to obtain the system information block required by the terminal on demand.

Optionally, the foregoing terminal determines, according to the configuration information, whether the other system information block stored by the terminal and the other system information block indicated by the configuration information have a target system information block that is inconsistent with the content, including: if the configuration The information includes a version number flag of each system information block in the other system information block, and the terminal determines whether a version number flag exists based on a version number flag of another system information block stored in the terminal and a version number flag in the configuration information. Is a consistent target system information block; or if the configuration information includes a special version number flag, the terminal determines that the system information block corresponding to the special version number flag is a target system information block, and the target system block is the The other system information block stored by the terminal is a target system information block that is inconsistent with the content in the other system information blocks indicated by the configuration information.

In this step, the version number flag of each system information block in the other system information blocks stored in the terminal may be compared with the version number of each system information block in the configuration information, and then the inconsistent target system information block is determined. For example, the version number of a certain system information block stored by the terminal is 001, and the version number of the system information block in the configuration information is 010, so that the system information block can be determined as the target system information block. The version number of the OSIB is the same. The terminal considers that the content of the OSIB stored on the UE is consistent with the content of the OSIB provided by the system. Otherwise, the terminal considers that the content of the OSIB stored by the terminal is inconsistent with the content of the OSIB provided by the system. At this time, if the terminal needs to acquire the content of the OSIB, it needs to initiate a request to the network side device. It should be noted that when the terminal does not store a certain OSIB information, the terminal also considers that the content of the OSIB stored by the terminal is inconsistent with the content of the OSIB provided by the system.

Optionally, the step of the terminal determining, according to the feature information of the terminal, whether the target system information block needs to be acquired to the network side device, includes: determining, by the terminal, the terminal based on feature information of the terminal Whether the target system information block indicated by the configuration information is required; if the terminal needs the target system information block indicated by the configuration information, the terminal determines whether the configuration information includes indicating that the network side device supports Availability of the target system information block And determining, if the configuration information includes the availability flag indicating that the network side device supports the target system information block, determining that the target system information block needs to be acquired from the network side device.

Through the above steps, after the target system information block in which the content is inconsistent is found, the terminal further determines whether the target system information block is needed. For example, the target system information block is multicast broadcast service system information, and the terminal currently needs to multicast the broadcast service, thereby determining that the target system information block is needed, and vice versa, determining that the target system information block is not needed. Therefore, it is determined that the target system information block needs to be obtained from the network side device when the terminal needs the target system information block, so that the target device information block can be obtained according to the requirement of the terminal, thereby saving signaling overhead and reducing the terminal and the network side. The energy consumption of the equipment.

Optionally, the step of determining, by the terminal, whether the terminal needs the target system information block indicated by the configuration information, based on the feature information of the terminal, includes: determining, by the terminal, the service information of the terminal Whether the terminal needs the target system information block indicated by the configuration information; or the terminal determines, according to the capability information of the terminal, whether the terminal needs the target system information block indicated by the configuration information.

The foregoing steps may be implemented to determine, according to the service information of the terminal, for example, the target system information block is a multicast broadcast service system information, and the terminal service information has a multicast broadcast service, thereby determining that the configuration information indication is required. The target system information block, if there is no multicast broadcast service in the service characteristic information of the terminal, thereby determining that the target system information block is not required; or the target service information block is OSIB5, and the service corresponding to the service characteristic information of the terminal is corresponding to OSIB5. And determining, by the service, the target system information block that is required by the configuration information, if the service corresponding to the service feature information of the terminal is not the service corresponding to the OSIB5, thereby determining that the target system information block indicated by the configuration information is not required. The service characteristic information can be used to obtain the system information block corresponding to the service feature information, and the system information block that does not correspond to the service feature information is not obtained, so as to save the signaling overhead and reduce the energy consumption of the terminal and the network side device.

In addition, it is also possible to determine, according to the capability information of the terminal, whether the target system information block is needed according to the foregoing steps. For example, it is determined that the target system information block is required only when the capability information of the terminal supports the service corresponding to the target system information block. Therefore, the system information block that is not supported by the capability information is avoided, so as to save the signaling overhead and reduce the energy consumption of the terminal and the network side device.

Optionally, the storage situation includes that the terminal stores other system information blocks, and the terminal And determining, by the terminal, the step of acquiring, by the network side device, the target system information block required by the terminal, according to the configuration information and the storing condition of the other system information block by the terminal, The configuration information and/or if the flag indicates that the configuration information of other system information blocks in the system information is different from the configuration information of other system information blocks in the system information sent by the network side device last time, The terminal acquires the configuration information; the terminal determines, according to the configuration information, whether the terminal stores the target system information block in another system information block indicated by the configuration information; if the terminal does not store And the target system information block in the other system information block indicated by the configuration information, the terminal determining, according to the feature information of the terminal, whether the target system information block needs to be acquired to the network side device.

The foregoing steps can be used to obtain configuration information and perform corresponding judgment when the terminal does not store other system information blocks indicated by the foregoing configuration information, so as to save radio resources and energy consumption of the terminal. For example, the other system information blocks indicated by the foregoing configuration information include the SIB3 to the SIB20, but the terminal only stores the SIB8 to the SIB20, thereby acquiring the configuration information and making corresponding determinations.

Optionally, the storage situation includes that the terminal does not store another system information block, and the terminal determines, according to the configuration information and the storage status of the other system information block, whether the terminal needs to be sent to the network side device. The step of acquiring the target system information block required by the terminal includes: if the flag bit indicates configuration information of other system information blocks in the system information and other systems in the system information sent by the network side device last time The configuration information of the information block is the same or different, and the terminal acquires the configuration information. The terminal determines, according to the configuration information, whether the terminal needs to acquire the terminal from the network side device. The required target system information block.

Through the above steps, in the case that the terminal does not store other system information blocks, the determination may be directly performed based on the foregoing configuration information. That is, when the terminal determines that the terminal does not store other system information blocks, the terminal directly determines based on the configuration information. For example, the terminal does not store other system information blocks, and the terminal determines that OSIB4 and OSIB5 are required according to requirements, and OSIB4 and OSIB5 are obtained from the network side device, and the terminal needs to obtain OSIB4 and OSIB5 according to requirements; OSIB5, and OSIB4 and OSIB5 are indicated in the configuration information indication, and the configuration indication information indicates that the network side device only supports OSIB4, and can obtain OSIB4 from the network side device; or the user determines other system information blocks indicated in the configuration information according to requirements. It is not a system information block required by the terminal, thereby determining that other system information blocks are not acquired from the network side device. The above steps can be used to determine whether the required system information block needs to be obtained from the network side device according to the configuration information, so that the energy consumption of the terminal can be saved.

Step 304: The terminal sends an acquisition request for acquiring the target system block to the network side device.

The foregoing obtaining request may be understood as a request message for requesting the network side device to acquire the target system information block. For example, the obtaining request carries the flag of the target system block, so that the network side device recognizes that the terminal needs the target. The system information block further sends the target system information block to the terminal according to the acquisition request.

Step 305: The terminal receives the target system information block that is sent by the network side device according to the acquiring request.

The step of receiving, by the terminal, the target system information block that is sent by the network side device according to the acquiring request, includes:

If the configuration information includes the scheduling information of the target system information block, the terminal receives the target system information block broadcasted by the network side device according to the scheduling information of the target system information block; or the terminal is Receiving the target system information block sent by the network side device on the dedicated signaling.

In the foregoing step, the terminal may receive the foregoing system information block sent by the network side device according to the foregoing scheduling information, where the network side device may send the target system information block in a broadcast form. For example, the scheduling information may be a broadcast period and a time-frequency resource of the target system information block, so that the terminal can receive the target system information block in time and accurately. In addition, since the network side device can send the foregoing target system information block by using dedicated signaling, the configuration information of the system information received in step 301 may not include scheduling information, thereby saving signaling overhead.

Optionally, after the step of receiving, by the terminal, the target system information block that is sent by the network side device according to the acquiring request, the method further includes: if the configuration information includes indicating the target system information block The content is a common version number flag of one of the plurality of contents predefined by the network side device and the terminal, the terminal storing a common version number flag of the target system information block; or if the configuration information Including indicating that the content of the target system information block is The special version number flag of a content other than the plurality of contents predefined by the network side device and the terminal, the terminal does not store the special version number flag of the target system information block.

The above steps may be implemented. After the terminal receives the target system information block, when the version number of the target system block is marked as the common version number identifier, the terminal can save the system information, so that if the network side device sends the system information again, The version number flag is the same as the stored flag so that the system information block can be not obtained. Because the current content is the latest content, it can save the energy consumption of the terminal and save the wireless resources. In addition, if the terminal acquires the target system information block, the terminal has previously stored the target system information block, and the terminal replaces the acquired target system information block with the previously stored one, and only saves the latest or all version number flags, wherein Here, all version number flags do not include the special version number flag, and are the version number flags in which the terminal has stored the corresponding system information block contents.

In addition, when the version number of the above system information block is a special version number flag, then the version number flag of the target system information block may not change when the content of the target system information block changes, so that the version number flag does not need to be stored in this case. In order to achieve the effect of saving terminal storage space. It is also possible to avoid situations in which the terminal error considers that the content of the stored system information block is related to the content of the latest system information block of the network. This is because the network may still use the special version number flag after updating the system information block, and does not change the special version number.

Optionally, after the step of receiving, by the terminal, the target system information block that is sent by the network side device according to the acquiring request, the method further includes: the terminal storing the target system information block.

Through the above steps, the terminal storage can obtain the target system information block from the network side device, so that the terminal can directly use the target system information block in the subsequent process without acquiring the target system information block of the same content again, so as to save the terminal. Terminal energy consumption and the effect of saving wireless resources.

In the system information block transmission method provided by the embodiment of the present disclosure, the terminal receives system information sent by the network side device, where the system information includes necessary system information of the terminal accessing the communication system, and configuration information of other system information blocks, The other system information block is a system information block in the communication system except the necessary system information, and the system information further includes a flag bit, where the flag bit is used to indicate other system information in the system information. Block configuration information and the network side design Whether the configuration information of the other system information blocks in the last transmitted system information is the same; if the flag bit indicates the configuration information of other system information blocks in the system information and the system information sent by the network side device last time The configuration information of the other system information blocks is the same, and the terminal determines whether the configuration information needs to be acquired according to the stored other system information blocks and the requirements of the terminal for other system information blocks, and if yes, the terminal is based on the configuration. The information and the terminal store the storage status of the other system information blocks, and determine whether the target system information block required by the terminal needs to be obtained from the network side device, and if yes, the terminal sends the target information to the network side device. The acquiring request of the system block; the terminal receiving the target system information block sent by the network side device according to the acquiring request. Since the terminal can accurately and efficiently initiate the request for acquiring the system information block according to the system information block stored by the user and the system information block configuration information of the network, the system information block transmitted by the network side device is only required by the terminal, and is not required.
