Embodiment 1
[0061] Please refer to image 3 , Embodiment 1 of the present invention is: a method for automatically switching cell types, comprising the following steps:
[0062] S1: The source base station sends a handover request message to the core network; specifically, when the measurement report reported by the mobile terminal meets the handover threshold, the source base station obtains the cell type in the current neighboring cell, and sends a handover request message according to the cell type To the core network, it triggers the handover preparation process and sends HandoverRequired to the core network.
[0063] S2: determine whether the core network returns a handover response signaling message (i.e. HandoverCommand signaling message), if so, then perform step S3, if not, then what the core network returns is a handover preparation failure signaling message (i.e. HandoverPreparationFailur signaling message), go to step S4.
[0064] S3: Determine that the cell type in the curr...
Embodiment 2
[0072] This embodiment is a specific application scenario of Embodiment 1.
[0073] In this embodiment, the type of the target cell (frequency point=39150 / PCI=199) is actually a macro type, and the threshold value T_threshold=4 is set.
[0074] In the neighbor cell list of the source base station, the cell type of the neighbor cell is initially home. After the terminal meets the handover threshold, the HandoverRequired message is used to trigger the S1 handover preparation process, which is carried in the signaling of procedureCode:id-HandoverPreparation(0) The IDs are as follows:
[0075] eNB-ID:homeENB-ID(1)
[0076] homeENB-ID:0006e860[bit length 28,4LSB pad bits,0000 0000 0000 01101110 1000 0110....decimal value 28294]
[0077] Then the core network responds to the HandoverPreparationFailure message, and the Cause carried is clearly marked radioNetwork:ho-failure-in-target-EPC-eNB-or-target-system(6), which means that the target base station cannot be identified.

Embodiment 3
[0084] This embodiment is a computer-readable storage medium corresponding to the above-mentioned embodiments, on which a computer program is stored, and when the program is executed by a processor, the following steps are implemented:
[0085] The source base station sends a handover request message to the core network;
[0086] If the core network returns a handover response signaling message, it is determined that the cell type in the current neighboring cell is valid and saved;
[0087] If the core network returns the handover preparation failure signaling message, then according to the handover preparation failure signaling message, it is judged whether the target base station number in the handover request message is wrong;
[0088] If yes, switch the cell type of the current neighbor cell.
[0089] Further, the "source base station sends a handover request message to the core network" is specifically:
[0090] When the measurement report reported by the mobile termina...
