Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, an embodiment of the present invention provides a method for sending system information, which is applied to a base station, and includes the following steps:
step 101: transmitting a control message for controlling transmission of the request message;
step 102: receiving a request message for requesting system information transmitted by a mobile communication terminal;
step 103: and sending the system information.
The system information may be information used for cell reselection by the mobile communication terminal. The mobile communication terminal may camp on the cell and be in an RRC connected state when transmitting the request message.
Thus, the system information sending method according to the embodiment of the present invention is capable of enabling the base station to send the control message for controlling the sending of the system information before sending the system information by sending the control message for controlling the sending of the request message, receiving the request message for requesting the system information sent by the mobile communication terminal, and sending the request message for controlling the sending of the request message by the mobile communication terminal according to the received control message, thereby controlling when the terminal requests the system information from the base station by the network, and realizing the ordered sending of the terminal request message.
In the embodiment of the present invention, since the base station has a lot of neighbor cell information, when the base station sends the neighbor cell information to the mobile communication terminal, the base station will occupy more downlink resources, and particularly, if the neighbor cell information is sent in a one-to-one manner through a dedicated signaling, more downlink resources will be consumed. Therefore, in order to avoid consuming excessive downlink resources, the base station can further control under what conditions the mobile communication terminal transmits the request message when controlling the mobile communication terminal to transmit the request message.
Specifically, the control message sent by the base station to the mobile communication terminal may carry one or more of the following thresholds of the control parameters: a received reference signal power, a received reference signal quality, and a signal to interference noise ratio of the received reference signal. It should be noted that, the thresholds of the control parameters carried in the control message sent by the base station are not limited to the thresholds of the three control parameters, and may also be thresholds of other control parameters according to specific situations, and the threshold of any one control parameter may be one or multiple, which is not limited in the embodiments of the present invention.
And after receiving the control message sent by the base station, the mobile communication terminal can send a 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 transmitted 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.
Therefore, the base station controls the mobile communication terminal to send the request message when the measured value of the control parameter meets the threshold condition, and the frequency of sending the request message by the mobile communication terminal can be reduced, so that the frequency of receiving the request message by the base station is reduced, the frequency of sending system information by the base station is reduced, and excessive downlink resources and uplink resources are prevented from being consumed.
Next, a procedure of transmitting a request message by the mobile communication terminal will be described by taking the control parameter as the received reference signal quality as an example.
For example, n thresholds for receiving reference signal quality, which are respectively T1, T2, and T3 … Tn, are carried in a control message sent by a base station, and the unit of the threshold is dB; when the mobile communication terminal performs the operation of measuring the quality of the received reference signal, the obtained measured values are X1, X2, X3 … Xn, respectively, where n is a natural number greater than or equal to 1.
One condition for sending a request message may be: if there is "Fi (Xi) is not more than or less than Ti, where i is a natural number between 1 and n, Fi being a function on the measured value Xi, such as Fi (Xi) -Xi-Offset, which is a preset value known to the mobile communication terminal or a value calculated from the known preset value", the mobile communication terminal transmits a request message to the base station;
alternatively, another condition for sending 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 on the measured value Xi, such as Fi (Xi) -Xi-Offset, which is a preset value known to the mobile communication terminal or a value calculated from the known preset value," the mobile communication terminal sends 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 the obtained measurement values does not have to be the same as the number of the thresholds of the corresponding control parameter carried in the control message, and may be different or the same, but whether the number of the obtained measurement values is the same may be determined according to the terminal requirements or predetermined conventions.
In the embodiment of the invention, in order to avoid consuming excessive downlink resources, the base station can control the condition of the mobile communication terminal to send the request message, and can also selectively send system information according to the terminal requirement. Therefore, the method for sending system information according to the embodiment of the present invention further includes:
and screening the system information sent in the step 103 from all the system information according to the screening parameters.
The screening parameters can be carried by a request message sent by the mobile communication terminal, and can also be determined by the base station according to the actual situation of the mobile communication terminal.
In this way, the base station selectively screens and transmits the system information from all the system information before transmitting the system information, thereby reducing the transmission amount of the system information and avoiding the consumption of excessive downlink resources.
In the embodiment of the present invention, 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. 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 filtering parameter is a parameter for indicating a target frequency band, the filtering parameter may be target frequency band information, such as B1, B2 … Bj, where j is a natural number greater than or equal to 1; or the screening parameter may be bit information, in this 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 bit information 0 and 1, so that the mobile communication terminal determines the corresponding bit information according to the target frequency band required by the mobile communication terminal itself, and carries the bit information through 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 indicating the location of the mobile communication terminal or the target cell, the screening parameter may be beam information such as beam ID where the mobile communication terminal is located, and the base station may determine the location of the mobile communication terminal or the target cell according to the beam information where the mobile communication terminal is located, so as to selectively screen the system information for transmission.
Further, it is to be noted that, when the mobile communication terminal transmits a request message for requesting system information, information in the request message may be carried and transmitted through one or more of message 1(message1), message 3(message3), and message 5(message5) of random access.
The above embodiment describes a system information transmission method on the base station side of the present invention, and a system information reception method on the terminal side of the present invention will be described below with reference to the embodiment and the drawings.
Referring to fig. 2, an embodiment of the present invention further provides a method for receiving system information, which is applied to a mobile communication terminal, and includes the following steps:
step 201: receiving a control message sent by a base station for controlling the sending of the request message;
step 202: transmitting a request message for requesting system information;
step 203: and receiving system information sent by the base station.
The system information may be information used for cell reselection by the mobile communication terminal.
Thus, the system information receiving method according to the embodiment of the present invention is capable of enabling a base station to send a control message for controlling sending of a request message before sending system information by receiving the control message sent by the base station for controlling sending of the request message, sending the request message for requesting system information, and receiving the system information sent by the base station, so that a mobile communication terminal sends the request message for requesting system information according to the received control message, thereby controlling when the terminal requests the base station for system information by a network, and realizing ordered sending of terminal request messages.
In the embodiment of the invention, the control message sent by the base station to the mobile communication terminal can carry one or more of the following thresholds of control parameters: a received reference signal power, a received reference signal quality, and a signal to interference noise ratio of the received reference signal.
Further, referring to fig. 3, on the basis of step 201 to step 203, the method for receiving system information according to the embodiment of the present invention may further include:
step 204: performing a measurement operation to obtain at least one measured value of the control parameter;
step 205: judging whether the measured value of the control parameter is less than or equal to the threshold of the control parameter;
wherein step 202 is performed when the measured value of the control parameter is less than or equal to the threshold of the control parameter, otherwise step 204 is performed.
Specifically, the request message may carry a screening parameter for the base station to screen the sent system information from all the system information.
Specifically, the screening parameter is a parameter for indicating a target frequency band.
Specifically, the control message carries an original parameter set, and the method for receiving system information according to the embodiment of the present invention may further include:

step 401: receiving a frequency band parameter which is sent by a mobile communication terminal and used for indicating a target frequency band;
step 402: and sending the system information.
