Exemplary embodiment of the present invention is more fully described below with reference to accompanying drawings.Although showing the present invention in attached drawing Exemplary embodiment, it being understood, however, that may be realized in various forms the present invention without should be by embodiments set forth here It is limited.It is to be able to be best understood from the present invention on the contrary, providing these embodiments, and can be by the scope of the present invention Completely it is communicated to those skilled in the art.

Term " comprising " and " having " in the specification and claims of the embodiment of the present invention and theirs is any Deformation, it is intended that cover it is non-exclusive include, for example, containing the process of series of steps or unit, method, system, production Product or equipment those of are not necessarily limited to clearly to list step or unit, but may include not listing clearly or for this The intrinsic other steps of processes, method, product or equipment or unit a bit.

As shown in Figure 1, the system information transmission method of the embodiment of the present invention, is applied to end side, specifically includes following step Suddenly：

Step 11：When it includes the first system information and second system information to need the other systems information asked, according to Default request configuration, corresponding solicited message is sent to base station.

Wherein, the first system information is that the instruction of minimum system information is by other of random accessing message one MSG1 requests Unite at least one of information other SI, and second system information is that the instruction of minimum system information passes through random accessing message three At least one of the other systems information of MSG3 requests, other systems information are the system letter in addition to minimum system information Breath.Wherein, minimum system information, which can be shown, indicates which other SI can be made requests on by MSG1, and not in minimum system The other SI indicated in information can be made requests on by MSG3, i.e., minimum system information hidden can also show which other SI indicated It can be made requests on by MSG3.That is, both having included being asked by MSG1 when terminal needs the other SI asked Other SI and when including the other SI asked by MSG3 are sent according to default request configuration to base station (gNB) corresponding Solicited message.Further, above-mentioned solicited message is for asking the first system information and second system information.

Specifically, for being in the terminal UE of Idle state/inactive state (idle/inactive), UE can pass through MSG1 Or MSG3 sends the solicited message of request other SI, when the other SI that UE needs both had included to be asked in a manner of MSG1 Other SI, and when including the other SI asked in a manner of MSG3, then can be configured according to pre-defined request send it is corresponding Solicited message.

Step 12：Receive the first system information and second system information that base station is sent according to solicited message.

Base station can feed back corresponding system information, terminal is connecing after the solicited message for receiving terminal transmission to terminal After receiving corresponding the first system information and second system information, the follow-up interactive strategy with base station is determined, such as whether carrying out small Area's gravity treatment etc..

Specifically, terminal, which can configure to determine how to base station by following request, sends request the first system information and second The solicited message of system information：

Configuration one, step 11 specifically include：Flow is asked to send the first solicited message to base station by MSG1 respectively, and Flow is asked to send the second solicited message to base station by MSG3.Wherein, the first solicited message is used to ask the first system information, Second solicited message is for asking second system information.This request configuration refers to that terminal asks flow to be asked by MSG1 respectively The first system information is sought, asks flow to ask second system information by MSG3.Wherein, other SI can be divided into multiple systems Resource block (other SIBlock, OSIB), OSIB1, OSIB2... etc., as illustrated in fig. 2, it is assumed that base station configuration passes through The other SI that MSG1 sends request are OSIB1, and the other SI that request is sent by MSG3 are OSIB2, i.e. the first system is believed Breath is OSIB1, and second system information is OSIB2, and when UE needs to obtain OSIB1 and OSIB2, UE passes through MSG1 transmissions pair respectively The request of OSIB1 is to obtain the OSIB1 of base station transmission；And the request to OSIB2 is sent to obtain base station transmission by MSG3 OSIB2.Wherein, shown in Figure 2 is scene of the override requests by MSG1 progress other SI requests.UE preferentially passes through MSG1 OSB1, base station (gNB) is asked to transmit the requested OSIB1 of UE.Then the request flow of MSG3 is carried out again, wherein MSG3's asks The flow is asked to be specially：UE to gNB send MSG1, gNB after receiving MSG1 to UE feed back MSG2, UE after receiving MSG2 to GNB, which sends MSG3, asks OSIB2, gNB to transmit the requested OSIB2 of UE.

Further, terminal asks flow to send the first solicited message to base station by MSG1 respectively, and passes through MSG3 When flow being asked to send the second solicited message to base station, the request sequence of the first solicited message and the second solicited message how is determined It can refer to following manner determination：

Mode one, respectively by MSG1 ask flow to base station send the first solicited message, and pass through MSG3 request stream The step of journey sends the second solicited message to base station, including：According to the sequence of priority from high to low, MSG1 requests are passed sequentially through Flow sends MSG1 to base station, asks flow to send MSG3 to base station by MSG3.Wherein, MSG1 asks the priority of flow high The priority of flow or MSG3 is asked to ask the priority of flow higher than the priority of MSG1 request flows in MSG3；Preferentially Grade is what base station was pre-configured and was sent to terminal, or was pre-configured for terminal.This mode is predefined request sequence, such as The other SI that the other SI or override requests that override requests are asked in a manner of MSG1 are asked in a manner of MSG3, this is predetermined The request sequence of justice can be configured by base station to UE, can also be to be pre-configured to be among terminal.Specifically, which is foundation MSG1 asks the priority of flow and MSG3 request flows, determines the request sequence of the first solicited message and the second solicited message, When MSG1 asks the priority of flow to ask the priority of flow higher than MSG3, terminal preferentially asks flow to base by MSG1 It stands and sends MSG1, then ask flow to send MSG3 to base station by MSG3.When MSG3 asks the priority of flow to be asked higher than MSG1 When seeking the priority of flow, terminal preferentially by MSG3 ask flow to base station send MSG3, then by MSG1 ask flow to Base station sends MSG1.It is worth noting that the priority of MSG1 request flows and MSG3 request flows can be by base station configuration distributing To terminal, can also be pre-configured before terminal manufacture.

Mode two, respectively by MSG1 ask flow to base station send the first solicited message, and pass through MSG3 request stream Journey to the base station send the second solicited message the step of include：It is random to determine asking for the first system information and second system information Seek sequence；Alternatively, according to the priority of the first system information and second system information, the first system information and second system are determined The request sequence of information；According to request sequence, flow is asked to send MSG1 to base station by MSG1 respectively, and asked by MSG3 Flow is asked to send MSG3 to base station.This mode is that terminal determines that the request of the first solicited message and the second solicited message is suitable at random Sequence or the priority of terminal other SI as needed determine asking for corresponding first solicited message and the second solicited message Sequence is sought, after determining request sequence, the request of other SI is carried out according to request sequence.This mode is that UE is independently determined The request sequence of other SI.Specifically which is the request sequence that UE determines other SI at random, or according to other SI Priority determines request sequence, and unrelated with being asked by which kind of mode.

Configuration one, step 11 can also further comprise：Flow is asked by MSG3, corresponding request letter is sent to base station Breath.This request configuration refers to that terminal asks flow to base station by a MSG3 while asking the first system information and second System information.

Further, how flow is asked by a MSG3 while asking the first system information and second system information can It is realized with reference to following manner：

Mode three asks flow by MSG3, includes to the step of base station transmission corresponding solicited message：It is asked by MSG3 Flow is sought, MSG3 is sent to base station.Wherein, MSG3 is for asking the first system information and second system information.This mode is The first system information and second system information are asked in MSG3 simultaneously.As shown in Figure 3, it is assumed that base station configuration is sent out by MSG1 It is OSIB1 to send the other SI of request, and the other SI that request is sent by MSG3 are OSIB2, i.e. the first system information is OSIB1, second system information are OSIB2, and UE needs to obtain OSIB1 and OSIB2, then UE can simultaneously be asked in MSG3 OSIB1 and OSIB2.Specifically, MSG3 asks flow specific as follows：UE to gNB send MSG1, gNB after receiving MSG1 to UE feeds back MSG2, and UE sends MSG3 to gNB after receiving MSG2 and asks OSIB1 and OSIB2, and it is requested that gNB transmits UE OSIB1 and OSIB2.

Mode four asks flow by MSG3, includes to the step of base station transmission corresponding solicited message：It is asked by MSG3 Flow is sought, MSG1 is sent to base station, receives the MSG2 that base station is sent according to MSG1；After receiving MSG2, asked by MSG3 Flow sends MSG3 to base station.Wherein, MSG1 for ask the first system information and instruction terminal need send MSG3 or Person indicates that request base station sends random accessing message two MSG2, MSG3 for asking second system information.Although this mode is Flow is asked to ask the first system information and second system information simultaneously by a MSG3, but since MSG3 asks to deposit in flow In the transmission of MSG1, therefore UE still asks the first system information by MSG1, and second system information is asked by MSG3.Such as figure Shown in 4, it is assumed that the other SI for sending request by MSG1 of base station configuration are OSIB1, and the other of request is sent by MSG3 SI is OSIB2, i.e., the first system information is OSIB1, and second system information is OSIB2, and UE needs to obtain OSIB1 and OSIB2, then UE asks the MSG1 in flow to ask OSIB1 by MSG3, and carries instruction information in MSG1, which indicates UE also It needs to send MSG3, namely instruction base station sends MSG2, UE sends in MSG3 asks the MSG3 in flow and asks OSIB2 It asks.Specifically, the request flow of MSG3 is specially：UE sends MSG1 request OSIB1 to gNB and carries instruction information simultaneously, with Instruction UE needs to send MSG3 or gNB is asked to send MSG2, and gNB feeds back MSG2 after receiving MSG1 to UE, and UE is being received Sending MSG3 to gNB after MSG2 asks OSIB2, gNB to transmit the requested OSIB2 of UE.

In the system information transmission method of the embodiment of the present invention, when the required other systems information other SI of terminal both Include MSG1 request the first system information, and include MSG3 request second system information when, according to default request configure to Base station requests the first system information and second system information, solving can not determine under this scene and carry out system in which way The problem of information request, to enable the terminals to normally obtain other SI, to ensure the follow-up interaction flow of terminal and base station Be normally carried out.
