Abstract
A system information broadcasting method and apparatus, and a system information receiving method and apparatus are provided. The system information broadcasting method includes: determining, by a first network device, first system information of a first cell, where there is no broadcast channel in the first cell and no system information is broadcast; and broadcasting, by the first network device, the first system information in a second cell of the first network device
Claims19
A method comprising:
- determining, by a first network device, first system information of a first cell, wherein there is no broadcast channel in the first cell and no system information is broadcast in the first cell;
- broadcasting, by the first network device, the first system information of the first cell in a second cell of the first network device;
- receiving, by the first network device, a system information change request message sent by a second network device, wherein the system information change request message comprises changed first system information;
- and
- determining, by the first network device, an effective time point of the changed first system information.

A method comprising:
- obtaining, by a terminal, first system information broadcast by a first network device in a second cell of the first network device, wherein first system information is system information of a first cell, and wherein there is no broadcast channel in the first cell and no system information is broadcast in the first cell;
- camping on or accessing, by the terminal, the first cell according to the first system information;
- monitoring for, by the terminal, a system information change message broadcast by the first network device in the second cell;
- and
- changing, by the terminal, the first system information according to the system information change message when the terminal receives the system information change message.
2 more elements
An apparatus, comprising:
- a processor;
- a non-transitory computer-readable storage medium storing a program to be executed by the processor, the program including instructions for:
- determining first system information of a first cell, wherein there is no broadcast channel in the first cell and no system information is broadcast in the first cell;
- a transceiver configured to broadcast the first system information of the first cell in a second cell of the apparatus;
- wherein the transceiver is further configured to receive a system information change request message sent by a second apparatus, wherein the system information change request message comprises changed first system information;
- and
- wherein the instructions comprise further instructions for determining an effective time point of the changed first system information.
