Embodiment 1

[0023] refer to figure 1 , which shows a flow chart of steps of a terminal access method provided by an embodiment of the present invention, which may specifically include the following steps:

[0024] Step 101: Determine the current coverage level information of the terminal according to the synchronization channel quality and physical downlink control channel quality of the cell where the terminal is located.

[0025]The coverage capability of the same terminal in different cells is different, and the terminal coverage level information is a reflection of the coverage capability. The solution of the embodiment of the present invention aims to perform network connection according to the current coverage level of the terminal, so as to avoid a low success rate of device accessing the network.

[0026] In the embodiment of the present invention, the current coverage level information of the terminal can be determined according to the synchronization channel quality and the phy...

Embodiment 2

[0063] refer to figure 2 , which shows a flow chart of steps of a terminal access method provided by an embodiment of the present invention, which may specifically include the following steps:

[0064] Step 201: Determine the current coverage level information of the terminal according to the synchronization channel quality and physical downlink control channel quality of the cell where the terminal is located.

[0065] In this embodiment of the present invention, the implementation manner of step 201 is similar to the implementation manner of step 101 in the first embodiment above, and will not be repeated here.

[0066] Step 202: Start a timer for timing.

[0067] After the current coverage level information of the terminal device is acquired, a preset timer is started for timing.

[0068] Step 203: Determine whether the terminal has received a physical uplink shared channel message.

[0069] When the timing time reaches the threshold time, it is judged whether the termi...

Embodiment 3

[0080] refer to image 3 , which shows a schematic structural diagram of a terminal access device provided by an embodiment of the present invention, which may specifically include:

[0081] The determining module 310 is used to determine the current coverage level information of the terminal according to the synchronization channel quality and the physical downlink control channel quality of the cell where the terminal is located; the judging module 320 is used to judge whether the terminal has received a physical uplink shared channel message; the target The value acquisition module 330 is used to adjust the maximum repetition value of the narrowband physical downlink control channel according to the preset rules according to the coverage level information when the terminal does not receive the physical uplink shared channel message, and obtain the target repetition value; wherein, the The target repetition value refers to the maximum repetition reference protocol value of t...

Abstract

The invention provides a terminal access method and device. The terminal access method comprises the steps: determining current coverage level information of a terminal according to synchronization channel quality and physical downlink control channel quality of a cell where the terminal is located; judging whether the terminal receives a physical uplink shared channel message or not; if not, adjusting the maximum repetitive value of the narrowband physical downlink control channel according to the coverage level information and a preset rule to obtain a target repetitive value, wherein the target repetition value refers to a maximum repetition reference protocol value of a narrowband physical downlink control channel under the current coverage level information, and the different coveragelevel information has different maximum repetitive reference protocol values of the narrowband physical downlink control channel; and executing an access process of the terminal according to the target repetition value. According to the invention, the success rate of terminal equipment access can be improved, and the network access KPI index is improved.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a terminal access method and device. Background technique [0002] NBIOT (Narrow Band Internet of Things, Narrowband Internet of Things) technology has gradually matured with the promotion of the Internet of Things. In the early days of NBIOT IoT, the main consideration was to fix the location of the connected devices (such as water meters, electric meters, manhole covers, etc.). parameter to ensure the access success rate of the access device. At present, with the gradual maturity of the Internet of Things, the access devices are located at the edge of the network (such as the basement) or in a fixed location (such as the boundary area of ​​coverage level information). Relevant parameters at a lower level reduce the access success rate of the access device, thereby reducing network KPI (Key Performance Indicators, key performance indicators) indicators. [00...
