Abstract

Embodiments of the present invention relate to the field of communications technologies, and disclose a method for transferring information between a base station and a terminal, a base station, a terminal, and a system, which diversify manners for transferring information between a base station and a terminal. The method includes: receiving a broadcast channel, where the broadcast channel is not only used for transferring basic physical layer configuration information of a cell, but also used for transferring first specific content agreed between the terminal and the base station, and the first specific content is used for transferring configuration information required by the terminal to access a network; and parsing out the first specific content from the broadcast channel. The present invention is mainly applied to transfer of information between a base station and a terminal.

First claim

What is claimed is:

1. A terminal, comprising:
a first receiving unit, configured to receive a broadcast channel, and send the received broadcast channel to a first parsing unit, wherein the broadcast channel is not only used for transferring physical layer configuration information of a cell, but also used for transferring first content between the terminal and a base station, and the first content is used for transferring configuration information required by the terminal to access a network;
memory, configured to store the broadcast channel; and
the first parsing unit, configured to receive the broadcast channel sent by the first receiving unit, and parse out the first content from the broadcast channel.

2. The terminal according to claim 1 , wherein:
the first content further comprises system information comprising at least some content of system information;
the first parsing unit further comprises: a first parsing subunit, configured to parse out the system information from the first content; and
the terminal further comprises:
a first acquiring unit, configured to acquire system configuration information according to the system information.

3. The terminal according to claim 1 , wherein:
the first content comprises first control information indicating how the terminal acquires second content; and
the terminal further comprises:
a second parsing unit, configured to receive the first content sent by the first parsing unit, parse out the first control information from the first content, and send the first control information that is parsed out to a second receiving unit, the second receiving unit configured to receive the first control information sent by the second parsing unit, and receive the second content in accordance with the first control information.

4. The terminal according to claim 3 , wherein:
the second content further comprises system information comprising at least some content of system information; and
the second receiving unit further comprises:
a second parsing subunit, configured to parse out, from the second content, the system information comprising the at least some content of the system information, and
a first acquiring subunit, configured to acquire system configuration information according to the system information.

5. The terminal according to claim 4 , wherein:
the second content comprises second control information, the second control information indicates how the terminal acquires third content;
the third content further comprises system information comprising at least some content of system information; and
the terminal further comprises:
a third receiving unit, comprising:
a third parsing subunit, configured to parse out the system configuration information from the third content, and
a second acquiring subunit, configured to acquire system configuration information according to the system information.

6. The terminal according to claim 5 , wherein the first content, the second content, and the third content are indicated by using a reserved bit in binary code identifying the broadcast channel.

7. The terminal according to claim 2 , wherein the broadcast channel is a physical broadcast channel (PBCH) or an enhanced physical broadcast channel (ePBCH).

8. A base station, comprising:
a hardware processing device configured to generate a broadcast channel; and
a broadcasting unit, configured to send the broadcast channel to a terminal, wherein the broadcast channel is not only used for transferring physical layer configuration information of a cell, but also used for transferring first content between the terminal and the base station, and the first content is used for transferring configuration information required by the terminal to access a network.

9. The base station according to claim 8 , wherein the first content further comprises system information comprising at least some content of system information, so that the terminal parses out the system information from the first content, and acquires system configuration information according to the system information.

10. The base station according to claim 8 , wherein the first content comprises first control information indicating how the terminal acquires second content, and the second content is used for transferring the configuration information required by the terminal to access the network, so that the terminal parses out the first control information from the first content; and receives the second content in accordance with the first control information.

11. The base station according to claim 10 , wherein the second content further comprises system information comprising at least some content of system information, so that the terminal parses out, from the second content, the system information comprising the at least some content of the system information, and further acquires system configuration information.

12. The base station according to claim 11 , wherein the second content comprises second control information, the second control information indicating how the terminal acquires third content, and the third content is used for transferring the configuration information required by the terminal to access the network, so that the terminal parses out the second control information from the second content and receives the third content in accordance with the second control information.

13. The base station according to claim 12 , wherein the third content further comprises system information comprising at least some content of system information, so that the terminal parses out, from the third content, the system information comprising the at least some content of the system information, and further acquires system configuration information.

14. The base station according to claim 12 , further comprising:
a first setting unit, configured to set a reserved bit of the broadcast channel according to the first content, the second content, and the third content, and/or identify the first content, the second content, and the third content by using a corresponding bit of the broadcast channel.

15. The base station according to claim 8 , wherein the broadcast channel is a physical broadcast channel (PBCH) or an enhanced physical broadcast channel (ePBCH).
