Background

In order to reduce signaling overhead, improve radio resource utilization, and reduce base station energy consumption, a 5 th generation communication System (5G System) proposes to divide System Information into two types, wherein one type is Minimum System Information (MSI), and the Other type is Other System Information (Other SI), wherein the Other SI includes all System Information except the Minimum SI. Further, the base station sends the minimum system information MSI to the terminal UE in a periodic broadcast manner. The UE may determine which message to request Other SI from the base station according to configuration information in the minimum system information of the base station.

In the 5G system, the base station may configure the UE to request other system information through a random access Message one (Message1, MSG1) or a Message three (Message3, MSG 3). However, when the other system information that the terminal needs to request includes both the system information requested through the Message one (Message1, MSG1) and the system information requested through the Message three (Message3, MSG3), the terminal cannot determine in what manner the request for the other system information is made.

Detailed Description

Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention can be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

The terms "comprises," "comprising," and "having," and any variations thereof, in the description and claims of embodiments of the present invention, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.

As shown in fig. 1, the system information transmission method according to the embodiment of the present invention is applied to a terminal side, and specifically includes the following steps:

step 11: and when other system information needing to be requested comprises the first system information and the second system information, sending corresponding request information to the base station according to preset request configuration.

Wherein the first system information is minimum system information indicating at least one of other system information other SI requested by the random access message one MSG1, the second system information is minimum system information indicating at least one of other system information requested by the random access message three MSG3, and the other system information is system information other than the minimum system information. Wherein the minimum system information may display information indicating which other SIs may be requested through MSG1, while other SIs not indicated in the minimum system information may be requested through MSG3, i.e., the minimum system information may also implicitly indicate which other SIs may be requested through MSG 3. That is, when the terminal needs to request the other SI including both the other SI requested through the MSG1 and the other SI requested through the MSG3, the corresponding request information is transmitted to the base station (gNB) according to the preset request configuration. Further, the request information is used for requesting the first system information and the second system information.

Specifically, for a terminal UE in idle/inactive (idle/inactive), the UE may send request information for requesting other SI through MSG1 or MSG3, and when the other SI required by the UE includes both the other SI requested in MSG1 and the other SI requested in MSG3, the UE may send the corresponding request information according to a predefined request configuration.

Step 12: and receiving the first system information and the second system information which are sent by the base station according to the request information.

After receiving the request information sent by the terminal, the base station feeds back corresponding system information to the terminal, and after receiving the corresponding first system information and second system information, the terminal determines a subsequent interaction strategy with the base station, such as whether to perform cell reselection or not.

Specifically, the terminal may determine how to transmit request information requesting the first system information and the second system information to the base station by the following request configuration:

the first configuration step 11 specifically includes: the first request information is transmitted to the base station through the MSG1 request procedure and the second request information is transmitted to the base station through the MSG3 request procedure, respectively. The first request message is used for requesting first system information, and the second request message is used for requesting second system information. This request configuration refers to the terminal requesting a flow through MSG1 to request first system information and requesting a flow through MSG3 to request second system information, respectively. As shown in fig. 2, it is assumed that the other SI configured by the base station and sending a request through MSG1 is OSIB1, the other SI sending a request through MSG3 is OSIB2, that is, the first system information is OSIB1, the second system information is OSIB2, and when the UE needs to acquire OSIB1 and OSIB2, the UE sends a request to OSIB1 through MSG1 to acquire OSIB1 sent by the base station; and sends a request for OSIB2 through MSG3 to obtain OSIB2 sent by the base station. Fig. 2 shows a scenario in which priority requests are made to the other SI request by MSG 1. The UE preferentially requests OSB1 through MSG1, and the base station (gNB) transmits OSIB1 requested by the UE. Then, a request flow of the MSG3 is performed, wherein the request flow of the MSG3 specifically includes: the UE sends MSG1 to the gNB, the gNB feeds back MSG2 to the UE after receiving MSG1, the UE sends MSG3 request OSIB2 to the gNB after receiving MSG2, and the gNB transmits the OSIB2 requested by the UE.

Further, when the terminal transmits the first request information to the base station through the MSG1 request procedure and the second request information to the base station through the MSG3 request procedure, respectively, how to determine the request order of the first request information and the second request information may be determined with reference to the following manners:

the first method, respectively sending the first request information to the base station through the MSG1 request flow and sending the second request information to the base station through the MSG3 request flow, includes: and according to the sequence of the priority levels from high to low, the MSG1 is transmitted to the base station through the MSG1 request flow in sequence, and the MSG3 is transmitted to the base station through the MSG3 request flow. Wherein, the priority of the MSG1 request flow is higher than that of the MSG3 request flow, or the priority of the MSG3 request flow is higher than that of the MSG1 request flow; the priority is either preconfigured for the base station and sent to the terminal or preconfigured for the terminal. This is a predefined request order, such as priority request for other SI requested by MSG1 or priority request for other SI requested by MSG3, which can be configured by the base station to the UE or pre-configured in the terminal. Specifically, the method determines the request sequence of the first request information and the second request information according to the priority of the MSG1 request flow and the priority of the MSG3 request flow, and when the priority of the MSG1 request flow is higher than the priority of the MSG3 request flow, the terminal preferentially sends the MSG1 to the base station through the MSG1 request flow and then sends the MSG3 to the base station through the MSG3 request flow. When the priority of the MSG3 request flow is higher than that of the MSG1 request flow, the terminal preferentially sends the MSG3 to the base station through the MSG3 request flow, and then sends the MSG1 to the base station through the MSG1 request flow. It should be noted that the priority of the MSG1 request procedure and the MSG3 request procedure may be configured by the base station to be sent to the terminal, or may be pre-configured before the terminal leaves the factory.

The second method, respectively sending the first request information to the base station through the MSG1 request flow and sending the second request information to the base station through the MSG3 request flow, includes: randomly determining a request sequence of the first system information and the second system information; or determining the request sequence of the first system information and the second system information according to the priority of the first system information and the second system information; the MSG1 is transmitted to the base station through the MSG1 request flow and the MSG3 is transmitted to the base station through the MSG3 request flow, respectively, in the order of the requests. The terminal randomly determines the request sequence of the first request information and the second request information, or the terminal determines the request sequence of the corresponding first request information and the second request information according to the priority of the other SI required, and after determining the request sequence, the terminal requests the other SI according to the request sequence. This way the UE autonomously decides the request order of the other SIs. Specifically, the method is that the UE randomly determines the request sequence of the other SI or determines the request sequence according to the priority of the other SI, and the method is not related to the request.

Step 11 may further include: and sending corresponding request information to the base station through the MSG3 request flow. This request configuration refers to the terminal simultaneously requesting the first system information and the second system information from the base station through one MSG3 request procedure.

Further, how to simultaneously request the first system information and the second system information through the one-time MSG3 request process may be implemented by referring to the following ways:

in a third mode, the step of sending corresponding request information to the base station through the MSG3 request flow includes: and transmitting the MSG3 to the base station through the MSG3 request flow. Among other things, MSG3 is used to request first system information and second system information. This is by requesting the first system information and the second system information simultaneously in MSG 3. As shown in fig. 3, assuming that the other SI configured by the base station and sending the request through the MSG1 is OSIB1, the other SI sending the request through the MSG3 is OSIB2, that is, the first system information is OSIB1, the second system information is OSIB2, and the UE needs to acquire OSIB1 and OSIB2, the UE may simultaneously request OSIB1 and OSIB2 in the MSG 3. Specifically, the MSG3 request flow is specifically as follows: the UE sends MSG1 to the gNB, the gNB feeds back MSG2 to the UE after receiving MSG1, the UE sends MSG3 requests OSIB1 and OSIB2 to the gNB after receiving MSG2, and the gNB transmits the OSIB1 and OSIB2 requested by the UE.

In a fourth mode, the step of sending corresponding request information to the base station through the MSG3 request flow includes: through the MSG3 request flow, the MSG1 is sent to the base station, and the MSG2 sent by the base station according to the MSG1 is received; upon receiving the MSG2, MSG3 is sent to the base station through MSG3 request flow. The MSG1 is used for requesting the first system information, and indicating that the terminal needs to send the MSG3 or indicating that the base station is requested to send the random access message two MSG2, and the MSG3 is used for requesting the second system information. Although the first system information and the second system information are simultaneously requested through the one-time MSG3 request process, the MSG3 request process includes the transmission of MSG1, so the UE still requests the first system information through MSG1 and requests the second system information through MSG 3. As shown in fig. 4, it is assumed that the other SI configured by the base station and sending the request through MSG1 is OSIB1, the other SI sending the request through MSG3 is OSIB2, that is, the first system information is OSIB1, the second system information is OSIB2, and the UE needs to acquire OSIB1 and OSIB2, the UE requests the OSIB1 through MSG1 in the MSG3 request flow, and carries indication information in MSG1, where the indication information indicates that the UE further needs to send MSG3, that is, indicates the base station to send MSG2, and the UE sends the request for OSIB2 in MSG3 in the MSG3 request flow. Specifically, the request flow of the MSG3 specifically includes: the UE sends an MSG1 request to OSIB1 to the gNB and carries indication information at the same time so as to indicate that the UE needs to send MSG3 or request the gNB to send MSG2, the gNB feeds back MSG2 to the UE after receiving the MSG1, the UE sends an MSG3 request to the gNB to request OSIB2 after receiving the MSG2, and the gNB transmits the OSIB2 requested by the UE.

In the system information transmission method of the embodiment of the invention, when other system information other SI required by the terminal comprises the first system information requested by the MSG1 and the second system information requested by the MSG3, the first system information and the second system information are requested to the base station according to the preset request configuration, so that the problem that the system information request cannot be determined in any mode in the scene is solved, the terminal can normally acquire the other SI, and the normal operation of the subsequent interaction process of the terminal and the base station is ensured.

The above embodiments respectively describe the system information transmission methods in different scenarios in detail, and the following embodiments further describe the corresponding terminals with reference to the accompanying drawings.

As shown in fig. 5, the terminal 500 according to the embodiment of the present invention can implement that when other system information that needs to be requested includes first system information and second system information, corresponding request information is sent to a base station according to a preset request configuration; the details of the method for receiving the first system information and the second system information sent by the base station according to the request information are received, and the same effect is achieved, wherein the request information is used for requesting the first system information and the second system information, the first system information is minimum system information indicating at least one of other system information requested by a random access message-MSG 1, the second system information is minimum system information indicating at least one of other system information requested by a random access message-MSG 3, and the other system information is system information except the minimum system information. The terminal 500 specifically includes the following functional modules:

wherein, the priority of the MSG1 request flow is higher than that of the MSG3 request flow, or the priority of the MSG3 request flow is higher than that of the MSG1 request flow; the priority is either preconfigured for the base station and sent to the terminal or preconfigured for the terminal.

The first sending sub-module 511 includes:

a processing unit 5112, configured to randomly determine a request order of the first system information and the second system information; or determining the request sequence of the first system information and the second system information according to the priority of the first system information and the second system information;

and the second sending submodule 512 is configured to send corresponding request information to the base station through the MSG3 request process.

The second sending submodule 512 includes:

a fifth transmitting unit 5124, configured to transmit the MSG3 to the base station through the MSG3 request procedure after receiving the MSG2, where the MSG3 is used for requesting the second system information.

It is worth pointing out that, in the embodiment of the present invention, when other system information other SI required by the terminal includes both the first system information requested by the MSG1 and the second system information requested by the MSG3, the first system information and the second system information are requested from the base station according to the preset request configuration, which solves the problem that it is impossible to determine in what manner to perform the system information request in such a scenario, so that the terminal can normally acquire the other SI, thereby ensuring that the subsequent interaction procedure between the terminal and the base station is performed normally.

When other system information other SI required by the terminal comprises the first system information requested by the MSG1 and the second system information requested by the MSG3, the terminal requests the first system information and the second system information from the base station according to the preset request configuration, so that the problem that the system information request cannot be determined in any mode in the scene is solved, the terminal can normally acquire the other SI, and the normal operation of a subsequent interaction process between the terminal and the base station is ensured.

The above embodiment describes the system information transmission method of the present invention from the terminal side, and the following embodiment further describes the system information transmission method of the base station side with reference to the accompanying drawings.

As shown in fig. 8, the system information transmission method according to the embodiment of the present invention is applied to a base station side, and specifically includes the following steps:

step 81: and the receiving terminal configures the sent request information according to the preset request.

The request information is used for requesting the first system information and the second system information. The first system information is the minimum system information indication requested by the random access message one MSG1, and the second system information is the minimum system information indication requested by the random access message three MSG 3. That is, when the terminal needs to request the other SI including both the other SI requested through the MSG1 and the other SI requested through the MSG3, the corresponding request information is transmitted to the base station (gNB) according to the preset request configuration. Further, the request information is used for requesting the first system information and the second system information.

Step 82: and sending the first system information and the second system information to the terminal according to the request information.

After receiving the request information sent by the terminal, the base station feeds back corresponding system information to the terminal, so that the terminal acquires the required first system information and second system information, and then determines a subsequent interaction strategy between the terminal and the base station, such as accessing the base station or ignoring the base station.

Specifically, step 81 specifically includes: the receiving terminal requests the first request information transmitted by the flow through the MSG1 and requests the second request information transmitted by the flow through the MSG3, respectively. The first request message is used to request the first system information, and the second request message is used to request the second system information. As shown in fig. 2, it is assumed that the other SI configured by the base station and sending the request through MSG1 is OSIB1, the other SI sending the request through MSG3 is OSIB2, that is, the first system information is OSIB1, and the second system information is OSIB2, when the UE needs to acquire OSIB1 and OSIB2, the UE sends a request to OSIB1 through MSG1 to acquire OSIB1 sent by the base station; and sends a request for OSIB2 through MSG3 to obtain OSIB2 sent by the base station. Fig. 2 shows a scenario in which priority requests are made to the other SI request by MSG 1. The UE preferentially requests OSB1 through MSG1, and the gNB transmits OSIB1 requested by the UE. Then, a request flow of the MSG3 is performed, wherein the request flow of the MSG3 specifically includes: the UE sends MSG1 to the gNB, the gNB feeds back MSG2 to the UE after receiving MSG1, the UE sends MSG3 request OSIB2 to the gNB after receiving MSG2, and the gNB transmits the OSIB2 requested by the UE.

Further, the terminal may transmit the request information to the base station according to a predefined request order. The first request information sent by the receiving terminal through the MSG1 request process and the second request information sent through the MSG3 request process are specifically: the receiving terminal sequentially passes through the MSG1 transmitted by the MSG1 request flow and the MSG3 transmitted by the MSG3 request flow in order of priority from high to low. Wherein, the priority of the MSG1 request flow is higher than that of the MSG3 request flow, or the priority of the MSG3 request flow is higher than that of the MSG1 request flow; the priority is preconfigured for the base station and transmitted to the terminal, or preconfigured for the terminal, the MSG1 is used to request the first system information, and the MSG3 is used to request the second system information.

Further, the UE may autonomously decide the request order of the other SIs. The first request information sent by the receiving terminal through the MSG1 request process and the second request information sent through the MSG3 request process are specifically: the receiving terminal requests the MSG1 transmitted by the flow through the MSG1 and the MSG3 transmitted by the flow through the MSG3 respectively according to the request sequence. The request sequence is randomly determined by the terminal, or the terminal is determined according to the priority of the first system information and the second system information; the MSG1 is used to request first system information and the MSG3 is used to request second system information.

In addition, step 81 may further include: the receiving terminal requests the request information sent by the flow through the MSG 3. This means that the terminal makes the request of the other SI through one MSG3 flow. Specifically, when the terminal requests the MSG3 in the MSG3 request flow to simultaneously request the first system information and the second system information, the request information sent by the receiving terminal through the MSG3 request flow specifically includes: the receiving terminal requests the MSG3 transmitted in the flow at MSG 3. Among other things, MSG3 is used to request first system information and second system information. Assuming that the other SI configured by the base station and sending the request through the MSG1 is OSIB1, the other SI sending the request through the MSG3 is OSIB2, that is, the first system information is OSIB1, and the second system information is OSIB2, as shown in fig. 3, the UE sends MSG1 to the gNB, the gNB feeds back the MSG2 to the UE after receiving the MSG1, the UE sends MSG3 requests to the gNB 1 and the OSIB2 after receiving the MSG2, and the gNB transmits the OSIB1 and the OSIB2 requested by the UE.

Or, when the terminal requests the first system information with MSG1 in the MSG3 request flow and requests the second system information with MSG3 in the MSG3 request flow, the request information sent by the receiving terminal through the MSG3 request flow is specifically: receiving MSG1 sent by the terminal in the MSG3 request flow; according to the MSG1, transmitting the MSG2 to the terminal; and the receiving terminal receives the MSG3 sent by the MSG 2. The MSG1 is used for requesting the first system information, and indicating that the terminal needs to send the MSG3 or indicating that the base station is requested to send the random access message two MSG2, and the MSG3 is used for requesting the second system information. Assuming that the other SI configured by the base station and sending the request through the MSG1 is OSIB1, the other SI sending the request through the MSG3 is OSIB2, that is, the first system information is OSIB1, and the second system information is OSIB2, as shown in fig. 4, the UE sends MSG1 to the gNB to request OSIB1 and simultaneously carries indication information to indicate that the UE needs to send MSG3 or request the gNB to send MSG2, the gNB feeds back MSG2 to the UE after receiving the MSG1, the UE sends MSG3 to the gNB after receiving the MSG2 to request OSIB2, and the gNB transmits the OSIB2 requested by the UE.

In the system information transmission method of the embodiment of the invention, the base station receives the request information of other system information sent by the terminal according to the preset request configuration, and sends the corresponding first system information and second system information to the terminal according to the request information, so that the terminal can normally acquire the other SI, thereby ensuring the normal operation of the subsequent interaction process of the terminal and the base station.
