Description
Technical Field

Background
Currently, in an Evolved network (Long Term Evolution, LTE), for some reasons, a cell access state may be set to "disallowed access" to indicate that the cell is not accessible, and an Evolved NodeB (eNB) carries a parameter of an "disallowed access" attribute in a broadcast message, so that an idle terminal may not reside in the cell after reading the information, and an active terminal may not be handed over to the cell. However, in the existing scheme, the eNB to which the neighboring cell of the cell whose state is changed belongs cannot acquire the access state of the cell, and the eNB may still switch the terminal to the cell, which results in that the terminal service is rejected, and the user experience is seriously affected.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
As shown in fig. 1, a cell 1 and a cell 2 are neighboring cells, and both the cell 1 and the cell 2 are normally used, that is, the cell state is "allowed to access", at this time, when a terminal moves from a location a to a location B, the terminal reports a measurement value related to the cell 2 to a base station to which the cell 1 belongs, and the base station to which the cell 1 belongs determines that the terminal can be switched to the cell 2 according to a switching judgment criterion; if the cell state of the cell 2 is changed to "not allow access" at a certain moment, according to the existing flow, the base station to which the cell 1 belongs still judges according to the measurement reported by the terminal and switches the terminal to the cell 2, however, since the state of the cell 2 is unavailable at this time, the base station to which the cell 2 belongs rejects the switching message sent by the base station to which the cell 1 belongs, and the terminal fails to switch from the cell 1 to the cell 2, which may directly cause the terminal to drop the call.
In view of the foregoing problems, embodiments of the present invention provide an information sending method and apparatus, and in the following embodiments, an example of changing an access state of a first cell is described, and a base station to which the first cell belongs is referred to as a first base station, and a base station to which a neighboring cell of the first cell belongs is referred to as a neighboring cell belonging base station.
The information sending method provided by the embodiment of the invention comprises the following steps: and if the first cell is started or the access state information of the first cell is changed, sending the access state information of the first cell to a base station to which the adjacent cell of the first cell belongs, wherein the access state information indicates whether the terminal is allowed to access the first cell or indicates the priority information of the terminal which is allowed to access by the first cell. The priority information may be a priority threshold, for example, a high priority threshold, that is, only a terminal with a priority higher than the priority threshold may access the first cell, or a low priority threshold, that is, only a terminal with a priority lower than the priority threshold may access the first cell; or the priority information may also be a priority list, that is, only terminals with priorities in the priority list may access the first cell; and sending the access state information of the first cell to a base station to which the adjacent cell of the first cell belongs.
In the implementation of the present invention, after a cell is started or a cell access state is changed, the access state information of the cell is notified to a base station to which a neighboring cell of the cell belongs, and the base station to which the neighboring cell of the cell belongs can perform a switching operation on a terminal according to the access state of the cell, for example, if the access state information indicates whether the terminal is allowed to access, when the cell is in a state of 'not allowing access', the base station to which the neighboring cell belongs does not switch the terminal to the cell; or when the cell is in the 'access permission' state, the base station to which the adjacent cell belongs can switch the terminal to the cell; or, if the access state information indicates priority information of a terminal allowed to access the first cell, when the base station to which the neighboring cell belongs needs to switch to the first cell, only the terminal with the priority meeting the priority information is switched to the first cell. Of course, the specific implementation may be performed according to the policies of the actual operator.

Referring to fig. 3, an embodiment of the present invention provides an information sending method, including:
s301, receiving access state information of the first cell sent by OAM.
In this embodiment, the OAM sets the access status of the first cell first, for example, if the first cell is originally in the "access allowed" status, it may be changed to the "access disallowed" status, and vice versa, or set the priority information of the terminal allowed to access the first cell. Specifically, the access status of the first cell may be set by an NMS or EMS in the OAM. The NMS, if set by the NMS, may send the access status information of the first cell to the first base station directly or send the access status information of the first cell to the first base station via the EMS; if set by the EMS, the EMS directly transmits access status information of the first cell to the first base station.

s401, the first base station sends a confirmation message to OAM;
in this embodiment, the base station sends a confirmation message to the OAM to notify the OAM that the access status of the first cell has been updated, for example, the base station directly sends the confirmation message to the NMS or the EMS, or sends the confirmation message to the NMS through the EMS.
S402, OAM sends the access state information of the first cell to the base station which the adjacent cell belongs to.
In this embodiment, OAM sends access status information of the first cell to the base station to which the neighboring cell belongs, specifically, if the NMS in S401 receives the confirmation message sent by the base station, the NMS sends the access status information of the first cell to the base station to which the neighboring cell belongs directly or through EMS, if the EMS in S401 receives the confirmation message sent by the base station, the EMS sends the access status information of the first cell to the base station to which the neighboring cell belongs directly.
Method four, as shown in fig. 5, S302 specifically includes:
s501, the first base station sends the access status information of the first cell to a Mobility Management Entity (MME).
In this embodiment, the first base station sends the access status information of the first cell to the MME through the S1 interface.
S502, the MME sends the access state information of the first cell to the base station to which the adjacent cell belongs.
In the embodiment of the invention, after the access state information of the cell is changed, the updated access state information of the cell is sent to the base station to which the adjacent cell belongs, so that the base station to which the adjacent cell belongs obtains the current access state information of the cell, thereby switching control can be carried out on the terminal according to the access information of the cell, and the switching control efficiency and the user experience degree are improved.
With reference to the scenario in fig. 2, an embodiment of the present invention provides an information sending method, as shown in fig. 6, including:

In this embodiment, the first base station sends the access state information of the first cell to the base station to which the neighboring cell belongs through an X2 interface. The X2 interface message may be an existing message, for example, if the X2 interface has been established between base stations, the access status information of the first cell may be transmitted through a base station configuration update message (eNB configuration update), or, if the X2 interface has not been established between base stations, through an X2 interface SETUP REQUEST message (X2SETUP REQUEST), or an X2 interface SETUP response message (X2SETUP response).
