Embodiment 1

[0062] Such as figure 1 As shown in FIG. 1 , it is a schematic flow chart of a cell access method provided in Embodiment 1 of the present invention. The method can be described as follows.

[0063] Step 101: The terminal device receives the system information sent by the serving cell where it resides.

[0064] Wherein, the system information includes a cell residency risk identifier and measurement information.

[0065] In step 101, when receiving the reference information sent by the serving cell, the terminal device selects the serving cell corresponding to the reference information to camp on.

[0066] During the process of selecting the serving cell to reside in, the terminal device receives reference information that includes reference information that increases the reflection path due to the influence of the lakeside effect.

[0067] Wherein, the reference information for increasing the reflection path due to the influence of the lakeside effect is sent by the service...

Embodiment 2

[0107] Such as figure 2 As shown in FIG. 2 , it is a schematic flow chart of a cell access method provided in Embodiment 2 of the present invention. Embodiment 2 of the present invention is an invention under the same inventive concept as Embodiment 1 of the present invention, and the method may be described as follows.

[0108] Step 201: The serving cell broadcasts system information.

[0109] Wherein, the system information includes a cell residency risk identifier and measurement information.

[0110] In step 201, before the serving cell broadcasts system information, the method further includes:

[0111] The cell camping risk identifier sent by the network side is received.

[0112] Among them, the methods of generating the cell residence risk identification include but are not limited to the following methods:

[0113] The first way:

[0114] First, the network side receives the cell access failure event information sent by the terminal device.

[0115] Wherein, th...

Embodiment 3

[0139] Such as image 3 As shown, it is a schematic structural diagram of a terminal device for cell access provided by Embodiment 3 of the present invention. Embodiment 3 of the present invention is an invention under the same inventive concept as Embodiment 1 to Embodiment 2 of the present invention. The terminal device includes: a receiving module 11, a determination detection module 12 and an access module 13, wherein:

[0140] The receiving module 11 is configured to receive system information sent by the serving cell where the cell resides, where the system information includes a cell residency risk identifier and measurement information;

[0141] A determination detection module 12, configured to determine, according to the cell residency risk identifier, that the serving cell is in a serving cell prone to the lakeside effect, and detect the signal quality of the serving cell according to the measurement information;

[0142] The access module 13 is configured to use t...

Abstract

Disclosed are a cell access method and device, comprising: a terminal device receives system information comprising residence risk identification and measurement information transmitted by a serving cell where the terminal device resides, and determines that the serving cell is a serving cell vulnerable to lake effect according to the residence risk identification of the cell, and detecting the signal quality of the serving cell according to the measurement information; utilizing the obtained signal quality information to determine whether lake effect currently occurs on the terminal device, and accessing the serving cell when determining that no lake effect currently occurs. Before accessing a serving cell, a terminal device determines whether lake effect occurs, so as to effectively allowing the terminal device within the coverage of the serving cell to access the base station device successfully, while timely identifying the terminal devices residing outside the coverage of the serving cell due to the lake effect and prohibiting access of the terminal devices to the serving cell, thus effectively avoiding access failure of terminal devices caused by lake effect.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a cell access method and device based on inconsistent coverage of uplink and downlink signals. Background technique [0002] With the development of communication technology, in order to achieve full coverage of the communication system, more and more base station devices are deployed. Some base station equipment is deployed indoors, some base station equipment is deployed in hotspot areas, some base station equipment is deployed on high mountains, and some base station equipment is deployed near water, etc. [0003] Because the signals transmitted and received by the base station equipment deployed at the water's edge are affected by the reflection of the atmosphere and water surface, a strong reflection path is formed, and when these reflection paths are superimposed with the direct path of the base station equipment, a strong signal is formed (This kind...
