Optionally, terminal can be by physical accidental access-in resource to base station transmission system information request, for example, can carry the system request information by above-mentioned MSG1.

Above-mentioned attribute information is used for the attribute of reflecting system information, can be the class indication of system information or the characteristic identification of system information.Wherein, class indication is used to indicate the classification of system information, and characteristic identification is used to indicate the characteristic of system information.

System information is segmented into different classes of according to the urgency level that the difference and terminal of its content obtain the system information, different classes of system information can be indicated with different classifications mark, such as, system information can be divided into according to class discrimination: cell selects system information relevant with gravity treatment, its class indication is 1, that is to say that the system information is SI1；Wireless channel configuration information, class indication 2 that is to say that the system information is SI2；BroadCast MultiCast Service pertinent system information, class indication 3 that is to say that the system information is SI3；The direct-connected operation system information of terminal, class indication 4 that is to say that the system information is SI4 etc..It should be noted that, above-mentioned mode classification only schematically illustrates, the classification of actual system information, and the form of corresponding class indication can be made an appointment by base station and terminal, such as, system information can be divided into the system information of cell reselection class according to class discrimination, its class indication is 00, the relevant system information of BroadCast MultiCast Service, class indication 01, the relevant system information of car networking, class indication 10.

System information can also be distinguished according to characteristic, to be divided into the system information of different characteristics, the system information of different characteristics can be indicated with different characteristics mark, such as, can be divided into system information according to the connection performance of terminal and base station: connected state pertinent system information, characteristic identification 00；Pertinent system information is accessed, Its characteristic identification is 01；Idle state pertinent system information, characteristic identification are 10 etc..

Wherein, system information request can indicate the attribute information of system information either explicitly or implicitly, system information request indicates that the attribute information of system information refers to system information request by identifying or indicating that attribute information is explicitly indicated in information by explicit mode, for example, the system information request can carry the mark of attribute information.For example, terminal wants the mark of the attribute information of the system information of request are as follows: 2, then what corresponding system information request carried is identified as 2.System information request indicates that the attribute information of system information refers to that system information request passes through specific Physical Random Access Channel (English: Physical RandomAccess Channel by implicit mode；Referred to as: the PRACH) attribute information for the system information that instruction terminal is requested indirectly.I.e. different PRACH resources corresponds to the attribute information (every group of attribute information includes at least two attribute informations) of different attribute information or different groups, when terminal is wanted to provide a kind of attribute information, just uses corresponding PRACH resource planning.For example, the corresponding attribute information of PRACH resource 1 be identified as the corresponding attribute information of 1, PRACH resource 2 be identified as 2, then terminal sends system information request using PRACH resource 2, i.e., what GC group connector wanted the attribute information of Request System information is identified as 2.

Step 202, base station receive the system information request that terminal is sent.

Optionally, base station can receive the system information request that terminal is sent by physical accidental access-in resource.For example, the system request information carries in above-mentioned MSG1.

Step 203, base station generate system information request response according to the system information request that terminal is sent, and system information request response includes transmission mode information, and the transmission mode information is for providing the transmission mode of system information.

In embodiments of the present invention, which includes mode of unicast or broadcast mode.Optionally, as shown in Fig. 2-2, the process that the system information request that base station is sent according to terminal generates system information request response may include:

The sum of the system information request of the carrying same alike result information received in step 2031, base station statistics preset duration.Execute step 2032 or step 2033.

In the embodiment of the present invention, it is preset according to specific implementation scene that preset duration is base station, such as several subframes.

The sum of the system information request of the carrying same alike result information received in the statistics preset duration of base station can carry out respective handling to the system information request of the carrying same alike result information according to the comparison result of the sum and preset quantity threshold value.Step 201 is please referred to, when system information request indicates the attribute information of system information by explicit mode, base station can count the number of identical mark or instruction information to determine the sum for the system information request for carrying same alike result information；When system information request is referred to by implicit mode Show the attribute information of system information, such as when different PRACH resources corresponds to different attribute informations, base station can count the sum of the system information request of each PRACH resource transmission, and each channel corresponds to a kind of system information request of attribute information.

Assuming that preset duration is the duration of 5 subframes, then base station counts the sum of the system information request of the inscribed carrying same alike result information received of 5 subframes, such as, base station receives the system information request of the mark 00 of 5 carrying attribute informations in preset duration, has received the system information request of the mark 01 of 22 carrying attribute informations.

Step 2032, when carrying the sum of system information request of same alike result information and being greater than preset quantity threshold value, base station generates system information request response, and the transmission mode that represents of transmission mode information in system information request response is broadcast mode.

It should be noted that above-mentioned preset quantity threshold value can be pre-set according to self transmission ability and transmitting scene for base station, for example, the preset quantity threshold value is 20.By taking the example in step 2031 as an example, the system information request for then carrying the mark 01 of attribute information is 22, greater than 20, then the transmission mode that the transmission mode information being directed in the system information request response of the system information request of the mark 01 of the carrying attribute information represents is broadcast mode.

Transmission mode information can represent broadcast mode in many ways in embodiments of the present invention, such as, when transmission mode information includes resource indication information or indicates that the transmission mode of system information is the mark of broadcast mode, transmission mode information represents the transmission mode of system information as broadcast mode；Wherein, resource indication information occupied transfer resource when being used to indicate system information with broadcast transmission, it should be noted that, the resource of resource indication information instruction can be part resource, it is also possible to whole resources, as long as guaranteeing that occupied resource is obtained when terminal can effectively determine that information is transmitted according to the resource indication information to carry out the effective of information.

Step 2033, when carry same alike result information system information request sum be not more than preset quantity threshold value when, base station generate system information request response, system information request response in transmission mode information instruction transmission mode be mode of unicast.

By taking the example in step 2031 as an example, the system information request for then carrying the mark 00 of attribute information is 5, less than 20, then the transmission mode that the transmission mode information being directed in the system information request response of the system information request of the mark 00 of the carrying attribute information represents is mode of unicast.

Transmission mode information can represent mode of unicast in many ways in embodiments of the present invention, when transmission mode information includes the sign of the system information needed for terminal is sent or indicates that the transmission mode of system information is the mark of mode of unicast, transmission mode information represents the transmission mode of system information as mode of unicast.

Wherein, the sign of the system information needed for terminal is sent is the request again for being used to indicate the system information that terminal can carry out needed for itself.

From above-mentioned steps 2032 and 2033, in the embodiment of the present invention, base station is when the sum for carrying the system information request of same alike result information is larger, indicate the transmission mode of broadcast, it that is to say subsequent using broadcast transmission system information, when the sum for carrying the system information request of same alike result information is smaller, indicate the transmission mode of unicast, it that is to say subsequent using mode of unicast Transmission system information, according to the sum of system information request and the comparison result of preset quantity threshold value come dynamic select transmission mode, it can be realized the flexible utilization of transfer resource, reach the compatibility of mode of unicast and broadcast mode.

Step 204, base station send system information request response to terminal.

Optionally, base station can send the feedback information of physical accidental access-in resource to terminal, which includes system information request response.The feedback information can be MSG2.

Step 205, terminal receive the system information request response that base station is sent.

Optionally, terminal receives the feedback information for the physical accidental access-in resource that base station is sent, and feedback information includes system information request response.The feedback information can be MSG2.

Step 206, terminal obtain the system information that base station is sent according to transmission mode information.

In embodiments of the present invention, transmission mode representated by transmission mode information is different, and the movement of acquisition performed by terminal is also different, and optionally, as Figure 2-3, according to transmission mode information, the process for obtaining the system information that base station is sent may include: terminal

Step 2061, terminal determine transmission mode provided by transmission mode information.Execute step 2062 or 2066.

In embodiments of the present invention, transmission mode includes mode of unicast or broadcast mode.Please refer to above-mentioned steps 2032 and 2033, when transmission mode information includes the sign of the system information needed for instruction terminal is sent or indicates that the transmission mode of system information is the mark of mode of unicast, transmission mode information represents the transmission mode of system information as mode of unicast；When transmission mode information includes resource indication information or indicates that the transmission mode of system information is the mark of broadcast mode, transmission mode information represents the transmission mode of system information as broadcast mode；Wherein, occupied transfer resource when resource indication information is used to indicate system information with broadcast transmission.

Step 2062 represents the transmission mode of system information as mode of unicast when transmission mode information, and terminal sends appointing system information request to base station, the system information of appointing system information request instruction terminal request either explicitly or implicitly.

Terminal can either explicitly or implicitly instruction terminal request system information, appointing system information Request indicates that the system information of the terminal request refers to appointing system information request by identifying or indicating that the system information of terminal request is explicitly indicated in information by explicit mode, for example, the appointing system information request can want the mark of the system information of request with carried terminal.For example, the desired request of terminal is other systems information: SI3, then what corresponding appointing system information request carried is identified as 3.Appointing system information request indicates that the system information of the terminal request refers to that appointing system information request passes through the system information of the indirect instruction terminal request of specific PRACH resource by implicit mode.I.e. different PRACH resources corresponds to the system information (every group of system information includes at least two system informations) of different system information or different groups, if terminal requests corresponding system information, just uses corresponding PRACH resource planning.For example, PRACH resource 1 corresponds to SI1, the corresponding SI2 of PRACH resource 2, then terminal sends appointing system information request using PRACH resource 2, i.e., that GC group connector wants request is SI2.

Optionally, terminal can establish solicited message by connection or connection establishes recovery or other radio resource control messages and sends appointing system information request to base station.Exemplary, terminal can carry the appointing system information request by above-mentioned MSG3.

Step 2063, base station receive the appointing system information request that terminal is sent.

It should be noted that base station can receive the appointing system information request that terminal establishes solicited message by connection or recovery is established in connection or other radio resource control messages are sent.Exemplary, which can carry in above-mentioned MSG3.

Step 2064, base station send appointing system information request response to terminal, which includes the system information of terminal request.

In above-mentioned steps 203, transmission mode information further includes resource indication information, correspondingly, base station is after receiving the appointing system information request that terminal is sent, appointing system information request response can be sent to terminal in transfer resource, by system information transmissions needed for terminal to terminal.

Step 2065, terminal receive the appointing system information request response that base station is sent, which includes the system information of terminal request.

Step 2066, when transmission mode information represents the transmission mode of system information as broadcast mode, terminal receives the system information that base station is sent by broadcast mode.

Optionally, in step 203, the transmission mode information in system information request response that base station generates further includes resource indication information, then in step 2065, base station sends appointing system information request response to terminal in transfer resource, correspondingly, terminal receives the system information that base station is sent by broadcast mode on transfer resource in step 2066.

Wherein, resource indication information includes transmission cycle, Physical Resource Block, modulation coding scheme and effectively passes At least one of defeated duration.

Wherein, transmission cycle is used to indicate the duration for carrying out the transmission of primary system information, such as 5ms；Physical Resource Block is used to indicate system information occupied resource block in transmission process；Modulation coding scheme is used to indicate the modulation coding scheme of system information, for example, by using Turbo coding mode；The effective duration of transmission that duration is used to indicate system information is effectively transmitted, that is to say, the system information transmitted in this duration is effectively that the system information beyond the duration belongs to null system information, for example, effective transmission duration can be 100ms.

Further, above-mentioned resource indication information can also including the number of transmissions etc. parameters, the embodiment of the present invention to this with no restriction.

In practical application, based on different resource indication informations, the difference of base station transmission system information, correspondingly, the mode that terminal receives system information is also different.

Such as, when resource indication information includes transmission cycle, base station carries out the cyclical transmission of system information according to the transmission cycle, terminal carries out the periodic receipt of system information according to the transmission cycle, for example, the desired request of terminal is other systems information: SI2, the transmission cycle that resource indication information includes is 5ms, then base station is every 5ms transmission primaries SI2, correspondingly, terminal receives the SI2 of base station transmission every 5ms；

When resource indication information includes the number of transmissions, the number of base station transmission system information is equal to the number of transmissions, the number that terminal receives system information is less than or equal to the number of transmissions, usually terminal repeats the movement for receiving system information, until being successfully received system information, stop receiving system information, or, after receive number is equal to the number of transmissions, stop receiving system information, such as, what terminal wanted request is other systems information: SI4, the number of transmissions that resource indication information includes is 2 times, then SI4 is transmitted twice in base station altogether, terminal repeats the movement for receiving SI4, until being successfully received SI4, or, after the 2nd execution receives SI4 movement, stop reception movement not being properly received SI3, because base station no longer carries out transmitting for the SI4；

When resource indication information includes modulation coding scheme, the modulating-coding of system information is carried out when base station transmission system information using the modulation coding scheme, terminal decodes the decoding demodulation that demodulation mode carries out system information using the modulation coding scheme accordingly, such as, what terminal wanted request is basic system information: SI1, the coding mode that resource indication information includes is Turbo coding mode, then terminal carries out the decoding of SI1 using the corresponding decoding process of Turbo coding mode；

When resource indication information includes transmission used resource, base station carries out the transmission of system information on the resource, and terminal carries out the reception of system information on the resource；

When resource indication information includes transmission effective time, base station carries out system in the transmission effective time The transmission of information, after receiving system information request response, terminal can repeat the movement for receiving system information, until being successfully received system information, stop receiving system information, or, it receives duration and reaches effectively transmission duration, stop receiving system information；Wherein, the duration that reception acts is executed when reception a length of time of reception responded since system information request, for example, the desired request of terminal is other systems information: SI3, a length of 10ms when effective transmission that resource indication information includes, then base station carries out the transmission of SI3 in the 10ms, and terminal carries out the reception of system information in the 10ms, until being properly received system information, stop reception movement, alternatively, until receiving duration exceeds 10ms, stopping reception movement.

It should be noted that, above-mentioned example is the explanation carried out by taking a parameter in resource indication information as an example, in practical application, since resource indication information includes at least one of transmission cycle, Physical Resource Block, modulation coding scheme and effective transmission duration etc., it is therefore desirable to above-mentioned executive mode be carried out appropriate combination according to the particular content in resource indication information.

For example, base station can repeat the sending action of system information after sending system information request response according to the transmission cycle when resource indication information includes: effective transmission duration and transmission cycle, until reaching effectively transmission duration, stop sending system information.Effective transmission duration can at the time of base station transmission system information request response timing.Correspondingly, terminal can repeat the movement for receiving system information according to the transmission cycle after receiving system information request response, until being successfully received system information, stop receiving system information, or, it receives duration and reaches effectively transmission duration, stop receiving system information；Wherein, the duration that reception acts is executed when reception a length of time of reception responded since system information request.

It is exemplary, it is assumed that a length of 10ms when effectively transmitting, transmission cycle 5ms, the number of transmissions 2, then base station needs to transmit 2 subsystem information by time interval of 5ms in 10ms.Terminal needs to repeat the movement for receiving system information as time interval using 5ms in 10ms, until being successfully received system information, stops receiving system information, alternatively, receiving duration reaches 10ms, stop receiving system information, alternatively, receive number is more than 2 times, stop receiving system information.

Optionally, terminal can send the feedback information that instruction is properly received system information to base station after being successfully received system information.Since base station can be with periodicity sending system information, it that is to say that system information may be sent repeatedly, and terminal just no longer needs to execution System Information reception after being properly received system information and acts, therefore, there may be successfully received system information when executing System Information reception movement for the first time to terminal, the feedback information plays corresponding suggesting effect, base station terminal can be prompted to be properly received systematicness, base station is upon reception of the feedback information in this way, it can stop the transmission of corresponding system information, no matter the system information the number of transmissions or effectively transmission duration whether reach the requirement of configured transmission, it all no longer needs to execute The sending action of system information, until next system information request is received, in this way it is possible to prevente effectively from the wasting of resources.

It should be noted that; the sequencing of system information acquisition method step provided in an embodiment of the present invention can carry out appropriate adjustment; step according to circumstances can also accordingly be increased and decreased; anyone skilled in the art is in the technical scope disclosed by the present invention; the method that variation can be readily occurred in; it should be covered by the protection scope of the present invention, therefore repeat no more.
