Detailed ways

The technical solutions in the embodiments of the present disclosure are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present disclosure. It is obvious that the described embodiments are a part of the embodiments of the present disclosure, and not all of the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present disclosure without departing from the inventive scope are the scope of the disclosure.

Referring to FIG. 1 , an embodiment of the present disclosure provides a system information sending method, which is applied to a base station, and includes the following steps:

Step 101: Send a control message for controlling transmission of the request message.

Step 102: Receive a request message sent by the mobile communication terminal for requesting system information.

Step 103: Send system information.

The system information may be information used by the mobile communication terminal to perform cell reselection. When transmitting the request message, the mobile communication terminal may camp on the cell and be in an RRC connected state.

In this way, the system information sending method of the embodiment of the present disclosure receives the request message for requesting system information sent by the mobile communication terminal by transmitting a control message for controlling transmission of the request message, and transmits system information, so that the base station can be Before transmitting the system information, sending a control message for controlling transmission of the request message, and the mobile communication terminal transmits a request message for requesting system information according to the received control message, thereby implementing when the network control terminal requests the system from the base station Information to achieve an orderly transmission of terminal request messages.

In the embodiment of the present disclosure, since the neighboring area information held by the base station is large, the base station will occupy more downlink resources when transmitting the neighboring area information to the mobile communication terminal, in particular, if the neighboring area information The one-to-one transmission is performed by dedicated signaling, and the downlink resources consumed will be more. Therefore, in order to avoid consuming excessive downlink resources, the base station may further control under what conditions the mobile communication terminal sends a request message when controlling the mobile communication terminal to send the request message.

Specifically, the control message sent by the base station to the mobile communication terminal may carry the following thresholds of one or several control parameters: a reference signal power, a received reference signal quality, and a signal and interference noise ratio of the received reference signal. It should be noted that the threshold of the control parameter carried in the control message sent by the base station is not limited to the thresholds of the foregoing three control parameters, and may be the threshold of other control parameters, and the threshold of any control parameter, depending on the specific situation. There may be one or more, and the embodiment of the present disclosure does not limit it.

After receiving the control message sent by the base station, the mobile communication terminal may send the request message according to the measured value of the control parameter and the threshold of the control parameter carried in the control message. Specifically, the request message may be sent by the mobile communication terminal when the measured value of the control parameter is less than or equal to the threshold of the control parameter.

In this way, the base station controls the mobile communication terminal to resend the request message when the measured value of the control parameter satisfies the threshold condition, thereby reducing the number of times the mobile communication terminal sends the request message, thereby reducing the number of times the base station receives the request message, and reducing the number of times the base station transmits the system information. To avoid consuming excessive downlink resources and uplink resources.

In the following, the process of transmitting a request message by the mobile communication terminal is described by taking the control parameter as the quality of the received reference signal as an example.

For example, the threshold of the quality of the received reference signal carried in the control message sent by the base station is n, which are respectively T1, T2, T3, ... Tn, and the unit of the threshold is dB; when the mobile communication terminal performs the measurement operation of receiving the reference signal quality, The obtained measured values are X1, X2, X3, ..., Xn, respectively, where n is a natural number greater than or equal to 1.

A condition for transmitting a request message may be: if there is "Fi(Xi) not greater than or less than Ti, where i is a natural number between 1 and n, Fi is a function of the measured value Xi, such as Fi(Xi) =Xi-Offset, Offset is a preset value known by the mobile communication terminal or a value calculated according to a known preset value, and the mobile communication terminal transmits a request message to the base station;

Alternatively, another condition for transmitting the request message may be: if for any i, "Fi(Xi) is not greater than or less than Ti, where i is a natural number between 1 and n, Fi is a function of the measured value Xi For example, Fi(Xi)=Xi-Offset, Offset is a preset value known by a mobile communication terminal or a value calculated according to a known preset value, and the mobile communication terminal transmits a request message to the base station.

It should be noted that when the mobile communication terminal performs the measurement operation of the control parameter, the number of measured values does not have to be the same as the threshold of the corresponding control parameter carried in the control message, and may be different or the same, and whether The same can be based on terminal requirements or pre-agreed.

In the embodiment of the present disclosure, in order to avoid consuming excessive downlink resources, the base station may selectively send the system information according to the requirements of the terminal, in addition to controlling the conditions of the mobile communication terminal to send the request message. Therefore, the system information sending method of the embodiment of the present disclosure further includes:

The system information sent in step 103 is filtered out from all system information according to the screening parameters.

The screening parameter may be carried by the request message sent by the mobile communication terminal, or may be determined by the base station according to the actual situation of the mobile communication terminal.

In this way, before transmitting the system information, the base station selectively selects system information for transmission from all system information, which can reduce the transmission amount of system information and avoid consuming excessive downlink resources.

In an embodiment of the disclosure, the screening parameter may be a parameter for indicating a target frequency band, a location of the mobile communication terminal, and/or a target cell. Wherein, when the screening parameter is a parameter for indicating a target frequency band, the screening parameter is generally carried by a request message sent by the mobile communication terminal. For example, when the screening parameter is a parameter for indicating a target frequency band, the screening parameter may be target frequency band information, such as B1, B2, . . . Bj, where j is greater than or equal to 1 natural number; or the screening parameter may be bit information, In the case, the base station may first broadcast a mapping table of the bit information and the target frequency band information. For example, if there are two target frequency band information, the two target frequency band information may be mapped by using the bit information 0 and 1 to enable the mobile communication terminal according to its own needs. The target frequency band determines the corresponding bit information and is carried by the request message.

When the screening parameter is a parameter for indicating the location of the mobile communication terminal and/or the target cell, the screening parameter is generally determined by the base station according to the actual situation of the mobile communication terminal. For example, when the screening parameter is a parameter for indicating the location of the mobile communication terminal or the target cell, the screening parameter may be beam information of the mobile communication terminal, such as beam ID, and the base station according to the beam where the mobile communication terminal is located The information can determine the location of the mobile communication terminal or the target cell, thereby selectively filtering system information for transmission.

In addition, it is to be noted that when the mobile communication terminal transmits a request message for requesting system information, the information in the request message may pass the randomly accessed message 1 (message 1), message 3 (message 3), and message 5 (message 5) One or more of them are carried and sent.
