Embodiment Construction

[0047] In order to make the object, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below with reference to the accompanying drawings and examples.

[0048] The embodiment of the present application provides an eMTC cluster implementation method. When reporting the eMTC capability information, the eMTC cluster terminal not only reports the eMTC PS capability information, but also reports the eMTC cluster capability information. According to the eMTC capability information reported by the eMTC cluster terminal, the base station is The eMTC cluster terminal determines the narrowband where it resides. This solution can realize trunking service bearer compatible with eMTC and B-TrunC.

[0049] The implementation process of the eMTC cluster in the embodiment of the present application will be described in detail below with reference to the accompanying drawings.

Abstract

The present application provides a method for implementing an eMTC cluster, the method comprising: an eMTC cluster terminal reports eMTC capability information to a core network through a base station; wherein, the eMTC capability information includes: eMTC PS capability information and eMTC cluster capability information; a core network server Start the eMTC cluster process according to the eMTC capability information reported by the eMTC cluster terminal, and determine that the eMTC cluster terminal resides in the eMTC; the base station determines the resident narrowband for the eMTC cluster terminal according to the eMTC capability information reported by the eMTC cluster terminal; the eMTC cluster terminal Receive the Attach Accept sent by the base station, and determine the narrowband where the eMTC cluster terminal resides. The method can realize trunking service bearer compatible with eMTC and B-TrunC.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to an enhanced machine type communication (eMTC) cluster realization method. Background technique [0002] For low-rate IoT services, 3GPP formulated the eMTC standard in R13. eMTC is used in Low Power Wide Area (LPWA) IOT applications. Typical applications include smart meter reading, smart parking, smart environment monitoring, smart agriculture, etc. The network side is required to provide: [0003] Coverage enhancement: 15dB enhancement compared to GPRS coverage; [0004] Low power consumption: the battery life can reach more than 5 years; [0005] Low cost: module <10$; [0006] Massive connections: a single cell supports 50,000 users. [0007] B-TrunC cluster can introduce eMTC technology to reduce terminal power consumption and improve cell coverage: [0008] Scenario 1: The eMTC mode is used in both the normal coverage area and the coverage enhancement area. ...
