Embodiment

[0030] A multi-mode user terminal signal detection and access method in this embodiment, such as figure 1 shown, including the following steps:

[0031] S1: The user terminal receives the synchronization signal broadcast by the cell of the signal transmitting device through multiple frequency bands, so as to obtain the cell identification information of the signal transmitting device.

[0032] Such as figure 2 As shown, the multi-mode terminal network framework may include multiple signal transmitting devices and multi-mode user terminals in different frequency bands. The number of signal transmitting devices and user terminals may be one or more. The figure is a schematic diagram of one user terminal and multiple signal transmitting devices, which is not limited in this embodiment of the present invention.

[0033] The range covered by a signal transmitting device is called a cell of a signal transmitting device, and an identifier of a signal transmitting device may also c...

Abstract

The invention discloses a multimode user equipment signal detection and access method. The objective of the invention is to solve the problem in the prior art that a user equipment cannot receive services when residing in a band cell satisfying an S criterion on an unlicensed band. The method comprises the following steps that: S1: a user equipment receives a cell broadcast synchronization signalfrom signal transmitting equipment through a plurality of frequency bands so as to obtain the cell identifier information of the signal transmitting equipment; S2, the user equipment receives a signalkeeping duration and a signal duration threshold according to the cell identifier information of the signal transmitting equipment; S3, the user equipment determines whether the signal transmitting equipment can access and reside in a cell of the signal transmitting equipment according to the signal holding duration and a signal duration threshold, wherein the cell access criterion of the signaltransmitting equipment at least comprises that the signal holding duration is greater than the signal duration threshold. By the method, the problem is solved that the user equipment cannot reside inand access the band cell or receive services when residing in the used licensed / unlicensed band cell meeting the S criterion.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a multi-mode user terminal signal detection and access method. Background technique [0002] With the rapid development of society, various applications in the five links of power generation, power transmission, power transformation, power distribution, and power consumption have exponential requirements for power supply and monitoring coverage, power quantity and power quality. The performance of the traditional power network has gradually failed to keep up with the growing demand for electricity. Based on this, a new generation of "smart grid" (SmartGrid, SG) came into being. [0003] In the prior art, the scheme of selecting the licensed frequency band for the resident cell generally occurs after the selection of the Public Land Mobile Network (PLMN), and the purpose is to select a channel as soon as possible after the User Equipment (UE) is powered on....
