The Minimum System Information (english: Minimum System Information) belongs to a part of the System Information, the System Information includes Minimum System Information and Other System Information (english: Other System Information), the Minimum System Information includes position Information, and the position Information is used for indicating the position of the base station.
Because the minimum system information is only one part of the system information, the data volume of the data transmitted by the base station is reduced, and the resource utilization efficiency is improved.
In step 102, when the location of the user equipment is changed, location change information transmitted from the user equipment is received.
The location change information is used to indicate that the location of the user equipment has changed.

Corresponding to the information transmission method provided in the embodiment corresponding to fig. 1, fig. 3 is a flowchart illustrating an information transmission method according to an exemplary embodiment, and is applied to a user device, where the user device may be a terminal device, such as a smart phone, a tablet computer, and the like. Referring to fig. 3, the information transmission method provided in this embodiment includes steps 301-302:
in step 301, minimum system information transmitted by the base station is received.
The minimum system information belongs to a part of system information, the system information includes minimum system information and other system information, the minimum system information includes location information, and the location information is used for indicating a location of the base station.
In step 302, when it is determined that the location of the user equipment has changed based on the location information, location change information is transmitted to the base station.
The location change information is used to indicate that the location of the user equipment has changed.
In one embodiment, the location information includes at least one of an area number and a cell identity, the area number indicating an area where the base station is located, and the cell identity indicating a cell provided by the base station.
In one embodiment, the area number includes a next generation core network local area number or a core network local area number.
Based on the information transmission method provided by the embodiments corresponding to fig. 1 and fig. 3, fig. 4 is an interaction diagram of an information transmission method shown according to an exemplary embodiment, and may be applied to a base station and a user equipment in an LTE system, where in the LTE system, the base station may be an eNB, and the user equipment may be a terminal equipment such as a smart phone, a tablet computer, and the like, and referring to fig. 4, the information transmission method provided by this embodiment includes steps 401 and 405:
in step 401, the base station acquires minimum system information.
The minimum system information is only a part of the system information. The minimum system information may include at least one of a core network local area number and a cell identity. Generally, in the LTE System, a base station periodically broadcasts and transmits System Information (System Information) on a Physical Broadcast Channel (PBCH), where the System Information includes Cell Access Related Information (such as a core Network local area number and a Cell identity), the System Information further includes a frequency bandwidth indicator, timer Information, a Public Land Mobile Network (PLMN) list of neighboring cells, and the like, and the Information occupies a large amount of resources, and if only minimum System Information is transmitted, the amount of Information can be reduced, and Network resources are saved.
In step 402, the base station periodically transmits minimum system information in the form of broadcasting.
In an LTE system, a base station can broadcast and send minimum system information to all directions through multiple times of beam forming, the multiple times of beam forming enhance the channel quality in multiple directions, and the information transmission quality is improved.
In step 403, the ue receives minimum system information transmitted by the base station.
Since the base station transmits the minimum system information in a periodic broadcast transmission, the ue receives the minimum system information every other period. The user equipment within the cell of which base station receives the minimum system information transmitted by which base station. For example, if the user equipment is in the cell of the base station a in the previous period, the user equipment receives the minimum system information of the base station a in the previous period, and if the user equipment is in the cell of the base station B in the current period, the user equipment receives the minimum system information of the base station B in the current period.
In step 404, the ue determines whether its location has changed according to the minimum system information received in the current cycle and the minimum system information received in the previous cycle.
Because the minimum system information includes the local area number of the core network and the cell identity, if the location of the user equipment changes, the minimum system information received in the previous period and the minimum system information received in the current period will be sent by two different base stations, if the cell where the user equipment is located changes, the cell identity indicated by the cell identity received in the previous period and the current period will be two cells, and if the area where the user equipment is located changes, the cell identity indicated by the local area number of the core network received in the previous period and the current period will be two different areas.
In step 405, when the user equipment determines that its location has changed, it transmits location change information to the base station.
The location change information is used to indicate that the location of the user equipment has changed. The location change information may be represented by one bit at a predetermined location, for example, at a predetermined bit, the location of the user equipment is changed by "1". If the user equipment determines that the position of the user equipment does not change, the user equipment sends the position change information to the base station before, the base station determines that the position of the user equipment does not change, and the user equipment does not need to send the information to the base station.
In the information transmission method provided by the embodiment of the present disclosure, the base station sends minimum system information to the user equipment, and receives location change information sent by the user equipment when the location of the user equipment is changed, where the location change information is used to indicate that the location of the user equipment is changed.
