Description

Information reporting and receiving method, device and storage medium
Technical Field
The present invention relates to the field of wireless communication technologies, and in particular, to an information reporting and receiving method, an information reporting and receiving device, and a storage medium.
Background
With the rapid development of wireless communication technology, internet of Things (IoT) technology comes up, where machine-to-machine (M2M) is an important direction for IoT development, and M2M devices are mostly smaller and smaller battery-powered systems, such as intelligent meter reading systems, and need to periodically monitor and report the use conditions of water, electricity, gas, and the like.
The concept of a Coverage Enhancement Level (CE Level) is introduced to NB-IOT terminals and Bandwidth Limited (BL) terminals. The CE Level is divided into three levels from 0 to 2, which respectively correspond to the signal attenuation against 144dB, 154dB and 164 dB.
The base station may configure a corresponding NPRACH (narrow band Physical Random Access Channel) resource for each CE Level. The terminal selects corresponding PRACH resources and PRACH retransmission times according to the CE Level where the terminal is located. When the random access procedure is not successful due to the Preamble transmission phase, the NB-IoT terminal will perform the random access procedure again on the NPRACH resource of a higher CE Level until all NPRACH resources of CE levels are tried.
However, for the NB-IoT terminal that successfully enters the MSg3 transmission phase of the RACH (Random Access Channel) in the Preamble phase, when the Random Access procedure fails, the NPRACH resource that retains the same CE Level is reserved for Random Access retry again. The premise of this design is that it is assumed that NB-IoT can enter MSg3 (Message 3, info 3) phase, i.e. CE Level selection representing the NB-IoT terminal is proper, and Preamble transmission can be successfully received by the base station.
Because the wireless network environment is constantly changing, the NB-IOT terminal may not successfully perform the random access Preamble transmission phase using the NPRACH resource corresponding to the CE Level that was last attempted to be randomly accessed, and if the CE Level and the maximum number of Preamble retransmissions are set to be inappropriate, unnecessary Preamble retransmissions may be caused, which may cause interference to the network, and may also increase the time delay for the NB-IOT terminal to access the network.

Detailed Description
In order to reduce network interference and reduce time delay of an internet of things terminal or a bandwidth-limited terminal accessing a network, embodiments of the present invention provide an information reporting and receiving method, an apparatus and a storage medium.
The preferred embodiments of the present invention will be described below with reference to the accompanying drawings of the specification, it being understood that the preferred embodiments described herein are merely for illustrating and explaining the present invention, and are not intended to limit the present invention, and that the embodiments and features of the embodiments in the present invention may be combined with each other without conflict.
The terminal random access process is as follows: a base station broadcasts an RSRP threshold corresponding to each CE Level, and RACH resources and configuration information corresponding to each CE Level on a BCCH (Broadcast Control Channel); the terminal measures the RSRP (reference signal received power) of the current serving cell and compares the RSRP with the threshold of the CE Level received on the BCCH to determine the coverage enhancement Level corresponding to the terminal. And initiating a random access process by using the corresponding PRACH resource parameter according to the determined coverage enhancement level. When the random access process fails in the Preamble transmission phase, the terminal may select an NPRACH (narrowband physical random access channel) resource corresponding to a higher-Level CE Level to perform a random access procedure again until all NPRACH resources corresponding to the CE Level are tried. If the set wireless network parameters such as the CE Level threshold, the maximum Preamble retransmission times and the like are not suitable, preamble retransmission can be caused, interference is brought to the network, and the time delay of the terminal accessing the network can be increased. Therefore, in the embodiment of the present invention, the terminal reports the relevant information in the random access process to assist the network side in setting more reasonable wireless network parameters such as the CE level threshold, the Preamble maximum retransmission times, and the like. Specifically, the terminal records information in the random access process during the random access process according to the CE level indicated by the network or the CE level selected by the terminal, selects a proper time to report to the base station, and reports to the network management device or the server by the base station to optimize the wireless network parameters.
As shown in fig. 1, which is a schematic view of an implementation flow of an information reporting method according to an embodiment of the present invention, the method may include the following steps:
s11, initiating a random access process by using the physical random access channel resource parameter corresponding to the initial coverage enhancement level.
Before sending a first Preamble, the terminal measures the RSRP of the current service cell, compares the RSRP with a CE Level threshold received from the BCCH, and determines an initial coverage Level according to the comparison result; or the terminal obtains the initial coverage enhancement level from signaling sent by the base station, where the signaling sent by the base station may include MAC (medium access control) signaling, RRC (radio resource control) signaling, or PDCCH order (for example, the base station has data to send to the terminal, and initiates the PDCCH order when detecting the terminal UL link lost), and so on.
In specific implementation, before initiating a random access procedure, the terminal first reads the BCCH to obtain an available RACH (random access channel) resource, and initiates the random access procedure according to the obtained RACH (random access channel) resource.
In this step, the terminal selects a preamble according to the available PRACH resource parameters corresponding to the initial coverage enhancement level, and initiates a random access procedure according to the maximum retransmission times of each preamble and the retransmission times of the preamble configured by the base station for the initial coverage level.
And S12, recording the log information of the random access channel when the random access response is received or the random access failure is judged.
In this step, the terminal records the log information of the current random access channel when receiving the random access response or judging that the current random access fails. The log information recorded by the terminal comprises at least one of the following items:
(1) RSRP (reference signal received power) of a current serving cell anchor carrier before initiating the first preamble;
i.e. RSRP of the current serving cell anchor carrier before the first Preamble (Preamble) is initiated.
(2) SINR (signal to interference plus noise ratio) of current serving cell anchor carrier before initiating the first preamble;
i.e. SINR of the current serving cell anchor carrier before initiating the first Preamble (Preamble).
(3) CQI (channel quality indication) of current serving cell anchor carrier before initiating the first preamble;
i.e. CQI of the anchor carrier of the current serving cell before the first Preamble (Preamble) is initiated.
(4) A serving cell identity.
(5) An initial coverage enhancement level determined prior to initiating the first preamble;
before initiating the first preamble, the terminal obtains the Level according to the CE Level determined by the measured RSRP or the indication (MAC or RRC or PDCCH order) from the eNB (base station).
(6) Coverage enhancement level used for random access message3 (MSg 3) transmission;
namely, when the preamble sent by the terminal is detected by the base station, the coverage enhancement level corresponding to the used PRACH resource.
(7) A resource number used for PRACH (physical random access channel) resource selection;
the resource number may be randomly selected by the terminal itself, or may be obtained according to a PDCCH (Physical Downlink Control Channel) order from the base station.
(8) The carrier number used for MSg3 transmission;
the carrier number may be a carrier number of an anchor carrier or may be a carrier number of a non-anchor carrier.
(9) The number of retransmissions of the Preamble when the Preamble response is received;
i.e. the last Preamble receives the response, this Preamble is retransmitted several times.
(10) GPS (global positioning system) geographical location information;
the geographical location information may be geographical location information of the terminal.
(11) Time stamp information.
The terminal records one or more items of the information and stores the information locally.
And S13, reporting the log information of the random access channel to network side equipment.
In specific implementation, the network side device related in the embodiment of the present invention may include a base station, a core network control plane functional entity, or a network management system.
In specific implementation, the terminal may select a suitable time to report the locally stored log information to the network side device, for example, the terminal may report the log information of the random access channel to the network side device in a process that the network side device initiates signaling-based minimization of drive test or cell-based minimization of drive test. The base station reports the received log information to network management equipment or a server, and the network management equipment or the server optimizes wireless network parameters after carrying out statistical processing on the received log information.
For better understanding of the embodiment of the present invention, the following describes an implementation process of the embodiment of the present invention with reference to a random access procedure of a terminal, and as shown in fig. 2, the implementation process may include the following steps:
s21, broadcasting the threshold corresponding to each CE Level and RACH resources and configuration information corresponding to each CE Level on the BCCH by the base station.
S22, the terminal reads the BCCH to acquire the available RACH resources.
And S23, the terminal determines the initial coverage enhancement level.
In this step, the terminal may determine the initial coverage enhancement level by any one of the following methods:
in the first method, before initiating a random access procedure, a terminal measures the channel quality of a current serving cell, and determines an initial coverage enhancement level according to a mapping relationship between the measured channel quality level of the serving cell and an initial coverage enhancement level configured by a base station.
For example, before initiating the random access procedure, the terminal measures RSRP of the current serving cell, and determines an initial coverage enhancement Level according to the measurement result and the CE Level obtained from the BCCH.
The second way, the terminal obtains the initial coverage enhancement level from the indication from the base station.
In specific implementation, the terminal may obtain the initial coverage enhancement level from MAC signaling, RRC signaling, PDCCH Order, or the like. For example, before initiating the random access procedure, the terminal acquires initial coverage enhancement level information from a MAC (medium access control) signaling or a PDCCH (physical downlink control channel) command transmitted by the base station.
And S24, the terminal initiates a random access process by using the physical random access channel resource parameter corresponding to the determined initial coverage enhancement level.
And S25, when the terminal receives the random access response, recording the log information of the random access channel.
S26, the terminal reports the log information of the random access channel to the base station.
And S27, the base station reports the received log information to the network management equipment or the server.
And the network management equipment or the server optimizes the wireless network parameters after performing statistical processing on the received log information.
In the information reporting method provided by the embodiment of the invention, the terminal records the selection of the PRACH process in the PRACH access process, and reports the selection to the network side in a log mode to assist the network side in optimizing the wireless network parameters, so that the network interference can be reduced, and the time delay of accessing the terminal to the network can be reduced.
