Superframe: a superframe includes 64 frames, and the unit of each superframe is 5120ms, in each superframe, frame number value Range is 0~63；

NB M2M system physical broadcast channel is divided into physical broadcast synchronizing channel (Physical Broadcast Synchronization Channel, PBSCH) and Physical Broadcast Channel (Physical Broadcast Channel, PBCH), it is mapped on different subcarriers on both channel frequencies.

Wherein PBSCH is used for the critical system information SI1 of bearing system synchronizing information and fixation, and cannot be by other systems Information is used.PBCH is made of, in a superframe for carrying other systems information the burst signal of a lasting 640ms Interior, there are 8 PBCH burst signals, PBCH fixes carrier block BCH_0, BCH_1 and the BCH_ for being divided into three types in the time domain 2, the information type of each carrier block and its carrying specifically sees Fig. 1, and every class carrier block has feature as shown in the table:

In order to enable the M2M equipment in preferable covering grade to have received all system informations as early as possible, network side must All system informations must have been sent in the shortest time；Meanwhile in order to support the M2M equipment of poor covering grade that can pass through The mode of soft merging gets correct system information, and network side can be repeated as many times and send identical broadcast message.

In NB M2M system, presently, there are 4 system broadcast information SI1~SI4, in which:

SI1 is sent on PBSCH, for information such as broadcast cell access control, cell selections；

BCH_0 block of the SI2 on PBCH is sent, and is used for RP Radio Paging parameter, random access channel (Random Access Channel, RACH) information such as parameter, power control parameters；

BCH_2 block of the SI3 on PBCH is sent, for information such as broadcast cell gravity treatment, adjacent area parameters；

BCH_1 block of the SI4 on PBCH is sent, for information such as broadcasting share networks.

With the extension of NB M2M system function, new SI may be will increase, newly-increased SI is according to information content size, only It can be carried on BCH_1 and BCH_2, base station must alternately be sent on identical physical channel new by time-multiplexed mode The SI of increasing, after increasing SI newly, the complete period for broadcasting primary each system information can be increased with it.Such as newly-increased SI5 and SI6, SI5 and SI6 are carried on BCH_1, then the complete period for broadcasting primary each system information is 3*640ms.

In this manner, if the SI newly increased causes a complete system message to repeat to send duration The integral multiple of non-8*640ms, then it is unordered for will lead to the system message type in each superframe, carried on BCH block.Such as In above example, after a complete system message is broadcasted 3 times, duration 9*640, then 8*640 it is lasting when In, which can only be broadcasted more than 2 times, when next superframe starts, understand the content of a then upper superframe Broadcast, cause in the next superframe, the frame number of the same type of system information carried on BCH block is changed, UE without Method directly determines the system information type carried on present frame, and such UE must receive all system informations Can just judge whether be required type SI, and when network side only has modified some system information, UE also must will be all System information all receives, and this processing mode, which is unfavorable for UE, reduces power consumption.Therefore, it is necessary to propose that a kind of method solves State problem.

Since the type for the system information being carried on BCH_1 and BCH_2 is likely to occur variation, such as some is increased newly The system information of type, or delete some multiplexing system information therefore in the present embodiment, can mainly calculate in the superframe It is carried on the frame number of every class system information on BCH_1 and BCH_2.

305, UE obtains the system information of corresponding types according to the frame number of every class system information.

It is exemplified below, such as newly-increased system information SI5 and SI6, SI5 and SI6 and SI4 are multiplexed, and are carried on BCH_1 On, BCH_2 carries SI3, carries S12 on BCH_0.

After UE obtains the system information SI1 carried on PBSCH, the carrier block BCH_1 for the PBCH for including in SI1 is obtained And number, type and the broadcast order of the system information carried on BCH_2.

UE is determined according to the number of the system information carried on BCH_1 and BCH_2 by what is carried on BCH_1 and BCH_2 Information of uniting all broadcasts the primary required time.

When the required time is 640ms, determine that the broadcast cycle of holonomic system information is 640ms；

Or when the required time is 2*640ms, determine that the broadcast cycle of holonomic system information is 2*640ms；

Or when the required time is 3*640ms or 4*640ms, determine that the broadcast cycle of holonomic system information is 4* 640ms；

Or when the required time is any one in 5*640ms, 6*640ms, 7*640ms and 8*640ms, really The broadcast cycle for determining holonomic system information is 8*640ms.

Specifically in the above example, the system information carried on BCH_1 has SI4, SI5 and SI6, and BCH_2 is upper only to be carried The quantity of the system information carried on a type of system information SI3, BCH_1 is more, therefore according to carrying on BCH_1 The quantity of system information determines that all the broadcast primary required time is 3* to the system information that will be carried on BCH_1 and BCH_2 640ms then can determine that the broadcast time of holonomic system information is 4*460ms.
