Embodiment 1

[0039] In order to solve the problem that the base station cannot obtain the real and effective resource information of the eMTC cell under the existing hybrid networking conditions, the embodiment of the present invention provides a hybrid networking resource information acquisition method, please refer to figure 1 , including the following steps:

[0040] Step S11: Send a resource status request to an adjacent base station.

[0041] The resource status request sent to the adjacent base station may include a cell type identifier and / or a BL / CE user resource identifier, and the cell type identifier may be used to distinguish cell types, such as eMTC LTE cells, pure LTE cells, etc. ; The BL / CE user resource identifier can be used to distinguish BL / CE users and ordinary users in the eMTC cell. It should be understood that the resource status request may not include the appealed cell type identifier and / or BL / CE user resource identifier, but it should be ensured that when the ad...

Embodiment 2

[0049] An embodiment of the present invention provides a hybrid networking resource information reporting method corresponding to the hybrid networking resource information acquisition method described in Embodiment 1. The hybrid networking resource information reporting method can request a pre-agreed format according to the resource status The difference is divided into two ways:

[0050] Method 1, see figure 2 , including the following steps:

[0051] Step S21: Receive a resource status request sent by the base station, where the resource status request includes a cell type identifier and / or a BL / CE user resource identifier.

[0052] It should be understood that the resource status request includes, but is not limited to, the cell type identifier and / or the BL / CE user resource identifier, and may also include the ID of the cell to be measured, the measurement period T, and the measurement start time t.

[0053] Step S22: Determine whether the resource status request cont...

Embodiment 3

[0071] On the basis of the first and second embodiments above, this embodiment of the present invention provides a method for acquiring and reporting hybrid networking resource information. Please refer to Figure 4 ,include:

[0072] S41: The base station sends a resource status request to a neighboring base station.

[0073] The information exchange between the local base station and the adjacent base stations can be accomplished through public signaling RESOURCESTATUS REQUEST, RESOURCE STATUS RESPONSE, and RESOURCE STATUS UPDATE on the X2 interface.

[0074] Specifically, in step S41, the base station sends a resource status request to an adjacent base station, please refer to Figure 5 , that is, the resource status request process, which can be started through the RESOURCE STATUS REQUEST message of the X2 interface. The RESOURCE STATUS REQUEST message may include resource message types that need to be reported: resource PRB of neighboring cells, TNL (base station transm...

Abstract

The embodiment of the invention provides a base station, a hybrid networking resource information acquisition method, a hybrid networking resource information report method and a cell switching method. The acquisition method comprises the steps of sending a resource state request to a neighbor base station; and receiving resource state report information fed back by the neighbor base station according to the resource state request, wherein the resource state report information comprises resource information of a neighbor cell requested by the resource state request, and when the neighbor cellis an enhanced machine type communication neighbor cell, the resource information comprises resource information distributed by the neighbor cell for a BL / CE user. The problem that when the neighbor call is the enhanced machine type communication neighbor cell, the resource report information is lack of the resource information distributed to the BL / CE user by the neighbor cell is solved, and thecondition that the base station can accurately and effectively acquire the resource information of the corresponding neighbor cell is ensured, so that the accuracy and effectiveness of a load balancing measure, such as cell switching, made according to the true resource information of each neighbor cell are ensured, and thus the communication quality of the terminal user is ensured, and the user experience of the terminal is improved.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method for acquiring, reporting and cell switching resource information of a base station and hybrid networking. Background technique [0002] eMTC (Enhanced Machine Type Communication) is one of the most popular Internet of Things technologies in the field of wireless communication at present. It is deployed based on the existing cellular mobile network and can support TDD (Time Division Duplexing) and FDD (Frequency Division) at the same time. Duplexing) two frame structures. eMTC has bandwidth reduction to uplink and downlink 1.4MHz and coverage enhancement. Therefore, when deploying eMTC to cells, only a few cells need to be deployed with eMTC to achieve continuous network coverage. Taking the deployment of eMTC on the LTE (Long Term Evolution, long-term evolution) system as an example, we provide BL (Bandwidth reduced Low complexity) / CE (Coverage En...
