Description

Information transmission method and system, base station, and computer-readable storage medium
Technical Field
The invention relates to the field of Internet of things, in particular to an information sending method and system, a base station and a computer readable storage medium.
Background
The number of connections of the internet of things terminal in 2020 is predicted to reach 50 hundred million. Operators urgently need to develop new service growth points to deal with the increasingly saturated situation of traditional person-to-person communication, and the internet of things becomes a research hotspot in recent years.
At present, the 3GPP standard adopts cellular network to carry NB-IoT (Narrow Band Internet of Things) and eMTC (enhanced Machine Type Communication) services, but the difference between the service carried by the conventional cellular network and the NB-IoT and eMTC services is relatively large. Therefore, the cellular network needs to be correspondingly enhanced and optimized in function so as to better meet the application requirements of the internet of things.
CIoT (Cellular Internet of Things) includes NB-IoT, eMTC, and the like.
The eMTC is evolved based on LTE protocol, the LTE network running at present is based on 3GPP R12 or a previous release, and the eMTC network to be upgraded is based on 3GPP R13 or a later release.
Fig. 1 is a diagram of R12 and the MIB structure of the previous version (MIB old structure). Fig. 2 is a diagram illustrating a conventional LTE MIB (R12 format) transmission period and timing schedule.
The conventional LTE terminal follows 3GPP R12 protocol, where R12 specifies that 14 bits in a legacy format MIB (Master Information Block) are valid bits and 10 bits are reserved bits, and the 10 reserved bits need to be filled with "0" according to the protocol specification.
As shown in fig. 2, R12 MIB is transmitted periodically (40ms), and is transmitted only in SF (Sub Frame) 0, where SFN (System Frame number) satisfies the condition that SFN% 4 is 0 is transmitted for the first time, and other 3 subframes 0 in the same MIB period are transmitted repeatedly, that is, R12 eNB transmits MIB once every 10 ms. The terminal can independently decode as long as receiving the MIB message in any 0 subframe, and can decode without waiting for all 4 MIB blocks to be collected. The R12 MIB is transmitted 4 times in total in the MIB period.
As shown in FIG. 2, subframe #0 includes 14 symbols (Symbol), from Sym0-Sym13, wherein PSS (Primary Synchronization Signal) is located at Sym5, SSS (Secondary Synchronization Signal) is located at Sym6, and MIB R12 is located at Sym7-Sym 10.
Fig. 3 is a diagram showing MIB structures of R13 and later versions (MIB new structures). Fig. 4 is a diagram illustrating eMTC MIB (R13 format) transmission period and timing arrangement.
Starting from the 3GPP R13 protocol to support eMTC, R13 specifies that 19 bits in the MIB (new format MIB) are valid bits and 5 bits are reserved bits, and the 5-bit reserved bits need to be filled with "0" as specified by the protocol.
R13MIB is sent periodically (40ms), and after eMTC feature is turned on, MIB is repeatedly sent in subframe #0 of every other radio frame within 40ms, and MIB is also repeatedly sent in subframe #9 of every radio frame.
Subframe #9 and subframe #0 of each radio frame include 14 symbols (symbols), respectively, from Sym0-Sym 13. PSS is located at Sym5 of subframe #0, SSS is located at Sym6 of subframe #0, MIB R13(1) is located at Sym7-Sym10 of subframe #0, MIB R13(2) is located at Sym3-Sym6 of subframe #9, MIB R13(3) is located at Sym7-Sym10 of subframe #9, MIB R13(4) is located at Sym11-Sym13 of subframe #9 and Sym3 of subframe #0, and MIB R13(5) is located at Sym4, Sym11-Sym13 of subframe # 0.
The coverage of the PBCH is improved by increasing the repetition times of the PBCH (Physical Broadcast Channel) in a 40ms transmission period. The R13MIB is transmitted 25 times in total in the MIB period.
After the eMTC feature is turned on in the R13 network, both the legacy LTE terminal and the eMTC terminal need to receive the new-format MIB, and the eMTC terminal can receive the new-format MIB normally, but some legacy LTE terminals discard the received new-format MIB message due to the reserved bit processing (the problem found in the eMTC terminal and the network IoT compatibility test). That is, the legacy LTE terminals with the defect cannot correctly receive the new format MIB messages, so that the defective legacy LTE terminals cannot randomly access to the R13 network that enables the eMTC feature, which has been found through eMTC terminal and network compatibility tests. This problem has a large impact on the access of these defective legacy LTE terminals to the R13 network.
Currently, there is no effective solution for the problem that these defective conventional LTE terminals cannot access the R13 network by 3 GPP.
