Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a terminal access method and apparatus.
Background
NBIOT (Narrow Band Internet of Things) technology has become mature with the push of the Internet of Things. In the initial NBIOT internet of things, position immobilization (such as a water meter, an ammeter, a well lid and the like) of access equipment is mainly considered, and relevant parameters under different coverage level information (level) are selected according to the received signal strength of the equipment at different positions when the equipment is accessed, so that the access success rate of the access equipment is ensured. At present, along with the gradual maturity of the internet of things, the position of the access equipment exists in a network edge zone (such as a basement) or a fixed position (such as a boundary zone of coverage grade information), and if the access equipment still adopts related parameters under corresponding levels under different coverage grade information, the access success rate of the access equipment is reduced, so that the indexes of Key Performance Indicators (KPIs) of the network are reduced.
In the current phase scheme, for Access devices, it is necessary to evaluate coverage level information of a cell in which a UE (User Equipment) is located according to received signal strength during Access, and select Random Access parameters at different levels for Access, which mainly relate to Nprach (Narrowband Physical Random Access Channel) Access location/period, Nprach repetition times, and maximum repetition times of Npdcch (Narrowband Physical downlink shared Channel). After the access device sends a preamble (random access preamble) at a corresponding position according to the level, the access device waits for scheduling of Npdcch, correctly receives a npdch Channel (Narrowband Physical Downlink Shared Channel) after decoding is correct, that is, receives an msg2 message, and at this time, the access device can send an npuch Channel (Narrowband Physical Uplink Shared Channel) to the base station side by msg 3. If the maximum number of times of npdcch repetition sent by the base station side reaches the maximum number of times under the level, the access equipment does not decode correctly, which will result in the failure of the random access.
Especially in NB-IOT Inband networking, NRS (Narrowband Reference Signal) power is set to 23dbm, and the maximum transmit power of the terminal is 23dbm, so that when the access device is in the edge zone of the network, the uplink and downlink power are equivalent, and the uplink and downlink channel limitation is not easy to distinguish. Referring to the protocol, the value range of the number of times of repetition of the Npdcch channel (r 1-r 2048), and the gain of the downlink Npdcch channel is improved by repeatedly sending the Npdcch channel for multiple times by combining the technical principle. However, when the access device is located at the boundary of different level levels or at the network edge zone, because of the limitation of the maximum repetition times of Npdcch at different level levels, the Npdcch decoding is often incorrect, and the terminal cannot be accessed, thereby affecting the access success rate of the device and causing the network access KPI index to be reduced.

Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below.
Example one
Referring to fig. 1, a flowchart illustrating steps of a terminal access method according to an embodiment of the present invention is shown, which may specifically include the following steps:
step 101: and determining the current coverage grade information of the terminal according to the quality of the synchronous channel and the quality of the physical downlink control channel of the cell in which the terminal is positioned.
The coverage capability of the same terminal in different cells is different, and the terminal coverage grade information is one embodiment of the coverage capability. The scheme of the embodiment of the invention aims to carry out network connection according to the current coverage level of the terminal so as to avoid the low success rate of accessing the equipment into the network.
The embodiment of the invention can determine the current coverage grade information of the terminal according to the quality of the synchronous channel and the quality of the physical downlink control channel of the cell in which the terminal is positioned.
In a CIoT (Cellular IoT) system, a terminal determines its coverage level information in a downlink measurement manner before a Random Access (Random Access), for example, the terminal determines the coverage level information according to the quality of a synchronization channel and the quality of a physical downlink control channel of a cell. Random access refers to a process from a terminal attempting to access a network by transmitting a random access preamble until a basic signaling connection is established with the network. And the terminal reports the coverage grade information selected by the terminal to the base station in the random access request.
And the base station schedules the terminal or switches the terminal coverage grade information according to the current coverage grade information of the terminal and the load condition or the data receiving condition (including the condition that the base station receives uplink data and the terminal receives downlink data) of the CIoT network. The scheduling of the base station to the terminal comprises downlink scheduling and uplink scheduling. Downlink scheduling refers to a base station scheduling terminal receiving Downlink data transmitted by a base station, and the Downlink data is transmitted through a PDSCH (Physical Downlink shared Channel). Uplink scheduling refers to that a base station schedules a terminal to transmit uplink data, and the uplink data is transmitted through a Physical Uplink Shared Channel (PUSCH). The base station generally transmits scheduling information including downlink scheduling information and uplink scheduling information through a PDCCH (Physical downlink control Channel). The PDCCH is used for carrying control information for scheduling PUSCH data and PDSCH data, and includes data transmission format, resource allocation, uplink and downlink scheduling grants, power control, retransmission information, and the like.
In practical application, a person skilled in the art may adopt other methods for acquiring the coverage level information of the terminal according to actual needs, and the embodiment of the present invention is not limited thereto.
In general, the coverage level information of the terminal may include three levels, level0, level1 and level2, where in the case of level0, the maximum number of repetitions of npdcch is small, and in the case of level2, the maximum number of repetitions of npdcch is large, and the maximum value is r 2048. The solution of the embodiment of the present invention is mainly explained for two cases of level0 and level1, and specifically, the three levels will be described in detail in the following embodiments, which are not described herein again.
After determining the current coverage level information of the terminal, step 102 is entered.
Step 102: and judging whether the terminal receives the physical uplink shared channel message.
After determining the current coverage grade information of the terminal, further judging whether the terminal receives the physical uplink shared channel message, when the terminal does not receive the physical uplink shared channel message, indicating that the channel quality of the cell where the terminal is located has a problem, if the maximum repetition frequency of the current coverage grade information needs to be adjusted to execute the access of the terminal, executing the next step 103; and when the terminal receives the physical uplink shared channel message, the channel quality of the cell in which the terminal is located is good, and the access of the terminal is directly executed according to the maximum repetition times of the current coverage grade information.
When the terminal does not receive the physical uplink shared channel message, step 103 is entered.
Step 103: and adjusting the maximum repeating number value of the narrow-band physical downlink control channel according to the coverage grade information and a preset rule to obtain a target repeating number value.
In this embodiment of the present invention, the target repetition number refers to a maximum repetition reference protocol value of the narrowband physical downlink control channel under the current coverage level information, and different coverage level information has different maximum repetition reference protocol values of the narrowband physical downlink control channel.

The first coverage level information may be level0 or level 1. When the first coverage level information is level0, the second coverage level information is level1, and when the first coverage level information is level1, the second coverage level information is level 2.
It can be understood that, when the first coverage level information is level0 and the terminal does not receive the Pusch message, the maximum repetition number value of Npdcch is adjusted to be the maximum repetition reference protocol value of Npdcch of level1, and then the access procedure of the terminal device is performed again with the maximum repetition reference protocol value of Npdcch of level 1. At the terminal, when the network access of the terminal device is unsuccessful with the maximum repetition number value of Npdcch of level1, the maximum repetition number value of Npdcch is continuously adjusted to be the maximum repetition reference protocol value of Npdcch of level2, i.e. r2048, and the access process of the terminal device is continuously executed with the maximum repetition reference protocol value of Npdcch of level2 as the target repetition number value.
When the first coverage level information is level1 and the terminal does not receive the Pusch message, the maximum repetition frequency of the Npdcch is adjusted to be the maximum repetition reference protocol value of the Npdcch of level2, that is, r2048, and then the access process of the terminal device is executed by taking the maximum repetition reference protocol value of the Npdcch of level2 as the target repetition value.

sub-step M2: comparing the quality of the synchronization channel and the quality of the physical downlink control channel with the first set value and the second set value;
sub-step M3: and determining the current coverage grade information of the terminal according to the comparison result.

When the quality of the synchronization channel of the cell where the terminal is located is smaller than the first set synchronization channel quality value and the physical downlink control channel quality value is smaller than the first set physical downlink control channel quality value, it can be determined that the coverage level information of the cell where the terminal is currently located is the first coverage level information.
And when the quality of the synchronous channel of the cell where the terminal is located is greater than the first set quality value of the synchronous channel and the quality value of the physical downlink control channel is greater than the first set quality value of the physical downlink control channel, comparing the quality of the synchronous channel of the cell where the terminal is located with a second set value respectively, and when the quality of the synchronous channel of the cell where the terminal is located is less than the second set quality value of the synchronous channel and the quality value of the physical downlink control channel is less than the second set quality value of the physical downlink control channel, judging that the coverage grade information of the cell where the terminal is located currently is second coverage grade information.
And when the quality of the synchronous channel of the cell where the terminal is located is greater than the quality value of the second set synchronous channel, and the quality value of the physical downlink control channel is greater than the quality value of the second set physical downlink control channel, the coverage grade information of the cell where the terminal is located can be determined to be third coverage grade information.
