Abstract
A method includes: broadcasting, by a network device, a minimum system information (MSI) message, where identification information of each SIB/system information block group in the MSI message includes an identifier of the SIB/system information block group and a type indication of the identifier, and the type indication of the identifier is used to indicate that a type of the identifier of the SIB/system information block group is an area specific system information identifier or a cell specific system information identifier. A corresponding terminal device and network device are also disclosed.
Claims19
A method comprising:
- broadcasting, by a network device, a minimum system information (MSI) message, wherein the MSI message comprises identification information of at least one system information block (SIB), respective identification information of each of the at least one SIB comprises:
- an identifier of a respective SIB included in the MSI message identifying a version of the at least one SIB;
- and
- a type indication of the respective SIB included in the MSI message, wherein the type indication of the respective SIB indicates whether a type of the respective SIB is area specific system information or cell specific system information, the type indication is carried in a field of the respective identification information, the field of the respective indication information is dedicated to indicating whether the respective SIB is area specific information or cell specific information, and the type indication of the respective SIB is one bit long.

A method, comprising:
- receiving, by a terminal device, a minimum system information (MSI) message from a network device corresponding to a target cell, wherein the MSI message comprises identification information of at least one system information block (SIB), respective identification information of each of the at least one SIB comprises:
- an identifier of a respective SIB included in the MSI message identifying a version of the at least one SIB;
- and
- a type indication of the respective SIB included in the MSI message, wherein the type indication of the respective SIB indicates whether a type of the respective SIB is area specific system information or cell specific system information, the type indication is carried in a field of the respective identification information, the field of the respective indication information is dedicated to indicating whether the respective SIB is area specific information or cell specific information, and the type indication of the respective SIB is one bit long;
- and
- further performing, by the terminal device:
- when an identifier of the at least one SIB in the target cell is partially the same as an identifier of at least one SIB in a cell in an area and that is stored by the terminal device, obtaining, by the terminal device, at least one SIB corresponding to an identifier of the at least one SIB in the target cell and that is different from the identifier of the at least one SIB stored by the terminal device;
- or
- when an identifier of the at least one SIB in the target cell is different from all identifiers of all SIBs stored by the terminal device, obtaining, by the terminal device, all SIBs in the target cell.

A network device, comprising:
- a transmitter, configured to broadcast a minimum system information (MSI) message, wherein the MSI message comprises identification information of at least one system information block (SIB), respective identification information of each of the at least one SIB comprises:
- an identifier of a respective SIB included in the MSI message identifying a version of the at least one SIB;
- and
- a type indication of the respective SIB included in the MSI message, wherein the type indication of the respective SIB indicates whether a type of the respective SIB is area specific system information or cell specific system information, the type indication is carried in a field of the respective identification information, the field of the respective indication information is dedicated to indicating whether the respective SIB is area specific information or cell specific information, and the type indication of the respective SIB is one bit long.
1 more element
A terminal device, comprising:
- a receiver, configured to receive a minimum system information (MSI) message from a network device corresponding to a target cell, wherein the MSI message comprises identification information of at least one system information block (SIB), respective identification information of each of the at least one SIB comprises:
- an identifier of a respective SIB included in the MSI message identifying a version of the at least one SIB;
- and
- a type indication of the respective SIB included in the MSI message, wherein the type indication of the respective SIB indicates whether a type of the respective SIB is area specific system information or cell specific system information, the type indication is carried in a field of the respective identification information, the field of the respective indication information is dedicated to indicating whether the respective SIB is area specific information or cell specific information, and the type indication of the respective SIB is one bit long;
- and
- a processor configured to:
- when an identifier of the at least one SIB in the target cell is partially the same as an identifier of at least one SIB in a cell in an area and that is stored by the terminal device, obtain at least one SIB corresponding to an identifier of the at least one SIB in the target cell and that is different from the identifier of the at least one SIB stored by the terminal device;
- or
- when an identifier of the at least one SIB in the target cell is different from all identifiers of all SIBs stored by the terminal device, obtain all SIBs in the target cell.
