Abstract

A method and a base station for storing code streams of broadcasting information are disclosed. The method includes the steps that: a base station reads configuration information to be broadcasted, fills the parameter information of the configuration information in the structure corresponding to the broadcasting information, encodes the broadcasting information to generate code streams and then stores the code streams; wherein during the storing step, the base station stores each piece of System Information (SI) of the broadcasting information in a format of code streams, the stored SI includes both the length of SI and the SI code streams. With the present disclosure, broadcasting information is stored in a format of code streams, thus the memory is saved extremely; each SI is stored in an identical storing area, thus the storage space is saved furthest and the efficiency is improved.

Claims

1. A method for storing code streams of broadcasting information, comprising the steps of:

a base station reads configuration information to be broadcasted, fills parameter information of the configuration information in a structure corresponding to the broadcasting information, encodes the broadcasting information to generate code streams and then stores the code streams;

wherein during the step of the base station stores the code streams, the base station stores each piece of System Information (SI) of the broadcasting information in a format of code streams, and the stored SI includes both a length section of SI and a SI code stream section;

wherein during the step of the base station stores each piece of said System Information (SI) of the broadcasting information in said format of code streams, the SI code stream section includes a head section and code streams of each System Information Block (SIB) mapped to the SI;

the base station stores each said SI in an identical storing area, and each said stored SI is arranged in order, so as to form an SI code stream structure; and

the stored SI code stream structure further includes an SI total number section; and

wherein said SI total number section occupies one byte;

the length section of each said SI occupies two bytes; and

the length of the SI code stream section is a sum of a length of the SI head section and a length of the code streams of all SIBs mapped to the SI.

2. The method according to claim 1, wherein the step of the base station stores the code streams comprises:

storing an encoded Master Information Block (MIB) and a first SIB in a format of code streams;

the stored MIB includes a length of the MIB and the code streams of the MIB, wherein the length of the MIB occupies one byte;

the stored first SIB includes a length of the first SIB and the code streams of the first SIB, wherein the length of the first SIB occupies one byte.

3. The method according to claim 1, further comprising the steps of:

the base station stores updated SI code streams after the broadcasting information is updated, and then determines whether the updated SI code streams and old SI code streams before said updating are the same.

4. A base station for storing code streams of broadcasting information, comprising an encoder, a filling device and a memory;

wherein

the encoder is configured to encode the broadcasting information to generate encoded code streams and send the encoded code streams to the filling device;

the filling device is configured to store the received code streams into the memory;

the memory is configured to store each code stream; and

the filling device is further configured to store each System Information (SI) of the broadcasting information in a format of code streams, wherein the stored SI includes a length section of SI and a SI code stream section;

wherein the filling device is configured as that;

the SI code stream section includes a head section and code streams of each System Information Block (SIB) mapped to the SI;

each said SI is stored into an identical storing area of the memory, wherein each stored SI is arranged in order so as to form an SI code stream structure; and

the stored SI code stream structure further includes an SI total number section; and

wherein said SI total number section occupies one byte;

the length section of each said SI occupies two bytes; and

the length of the SI code stream section is a sum of a length of the SI head section and a length&

of the code streams of all SIBs mapped to the SI.

5. The base station according to claim 4, wherein the filling device is further configured to:

store a Master Information Block (MIB) in a format of code streams, wherein the stored MIB includes a length of the MIB and the code streams of the MIB, and the length of the MIB occupies one byte; and

store a first SIB in a format of code streams, wherein the stored first SIB includes a length of the first SIB and the SI code streams of the first SIB, and the length of the first SIB occupies one byte.

6. The base station according to claim 4, wherein the filling device is further configured to:

store updated SI code streams after the broadcasting information is updated, and-determine whether the updated SI code streams and old SI code streams before said updating are the same.
