Description

Technical Field

[0001] This application relates to the field of communication technologies, and in particular, to a downlink data processing method, apparatus, and communication device. Background Art

[0002] In an Internet of Things (IoT) system, a frame schedule table has a period of 64 frames; a downlink physical channel occupies a fixed time slot therein with a period of 8 frames. After a current IoT terminal powers on and registers with the network side, if it supports the long listening mode, then the terminal has to continuously listen for the downlink physical channel on the fixed time slot to receive downlink data frames. For each terminal within the coverage range of the network side, it listens for and receives each data frame sent by the access network; each terminal passes the data frame to the protocol stack through the physical layer. After the protocol stack parses the terminal identifier in the data frame header and confirms that the data frame is sent to this terminal, it continues with subsequent processing, otherwise it discards the frame. For the terminal side, a terminal has to listen for and receive all downlink data frames on the fixed time slot; pass the data frame to the protocol stack through the physical layer. After the protocol stack parses the terminal identifier in the data frame header and confirms that the data frame is sent to this terminal, it continues with subsequent processing, otherwise it discards the frame. Based on the method in the related art, due to the large number of terminals, this method causes a large number of terminals to perform a large amount of ineffective listening, receiving, and frame header parsing, thereby resulting in high terminal power consumption and resource waste.

[0029] It should be noted that the above one or more processors and / or other data processing circuits are generally referred to as "data processing circuits" herein.

It should be pointed out that Figure 1 is only an example of a specific specific instance and is intended to show the types of components that may exist in the above computer terminal.

[0034] Under the above operating environment, an embodiment of a downlink data processing method is provided in the embodiments of the present application. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and although the logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in a different order than here.

[0035] Figure 2 is a flowchart of a downlink data processing method according to an embodiment of the present application. As Figure 2 shown, the method includes the following steps:

[0036] Step S202, obtain a Temporary Mobile Subscriber Identity (TMSI) assigned to the terminal side from the network side;

[0037] Step S204, perform a modulo operation on the TMSI and a preset value, and determine a data frame with a specified frame number according to the modulo operation result;

[0038] In step S204, the preset value can be set according to the actual scenario. For example: 10. While the terminal performs a modulo operation on the preset value, the network side also performs a modulo operation on the preset value.

[0039] Step S206: Ignore data frames with other frame numbers, listen for data frames with the specified frame number, and receive the data frames with the specified frame number sent by the network side.

[0040] In step S206, the terminal only listens for data frames with the specified frame number and receives the data frames with the specified frame number sent by the network side.

[0041] Through the above steps S202 to S206, the temporary mobile subscriber identity TMSI assigned to the terminal side is obtained from the network side; the modulo operation is performed on the TMSI and a preset value, and the data frame with the specified frame number is determined according to the modulo operation result; data frames with other frame numbers are ignored, the data frame with the specified frame number is listened for, and the data frame with the specified frame number sent by the network side is received. By only listening for data frames with the specified frame number, receiving downlink data frames achieves the purpose of reducing ineffective listening, thereby realizing the technical effect of improving the resource utilization rate of the terminal, and further solving the technical problem of low resource utilization rate of the terminal in the related art. The following is a detailed description.

[0042] In some embodiments of the present application, the specific steps for determining the data frame with the specified frame number according to the modulo operation result are as follows: obtain the last digit of the frame number of the downlink data frame; determine the data frame with the last digit of the frame number being the same as the modulo operation result as the data frame with the specified frame number.

[0043] Specifically, taking the preset value as 10, there are 10 kinds of modulo operation results, 0, 1, 2, 3, 4, 5, 6, 7, 8, 9. If the result of the terminal's TMSI mod 10 is 3, then the terminal will only listen for data frames with the last digit of the frame number being 3, and the remaining data frames are all ignored.

[0044] When the network side sends downlink data frames to the terminal, they are sent on a fixed batch of selected frame numbers. The rule for selecting frame numbers is that the last digit of the frame number is the same as the result of TMSI mod 10. In the above manner, for the network side, a downlink data frame sent by the access network (network side) no longer needs to be listened for by each terminal; for the terminal, a Tiantong Internet of Things terminal no longer needs to listen for all downlink data frames in a fixed time slot, but only needs to listen for several selected data frames, reducing the power consumption of the terminal and also saving resources, improving the resource utilization rate.

[0045] In the related art, the current Internet of Things standard requires the terminal protocol stack to complete the parsing of the downlink data packet header and determine whether the current downlink data packet is sent to the terminal according to the parsed terminal identifier. The process of receiving downlink data is as Figure 3As shown in the figure, each terminal within the coverage range of the network side listens to and receives each data frame sent by the access network; each terminal passes the data frame to the protocol stack through the physical layer. After the protocol stack parses the terminal identifier in the data frame header and confirms that this data frame is sent to this terminal, it continues with subsequent processing; otherwise, it discards the data frame. Therefore, in the related art, by passing the data frame to the protocol stack through the physical layer and having the protocol stack parse the terminal identifier in the data frame header, the protocol stack that can identify whether this data frame is sent to this terminal is awakened multiple times, and the terminal power consumption is relatively high. To solve the above problems, the specific steps of the downlink data processing method proposed in the embodiments of this application for receiving the data frame with the specified frame number sent by the network side are as follows: receiving a preset message sent by the protocol stack on the terminal side through the physical layer on the terminal side, where the preset message contains the identifier of the terminal side; receiving the data frame with the specified frame number sent by the network side through the physical layer on the terminal side according to the identifier of the terminal side.

[0046] Among them, the specific steps of receiving the data frame with the specified frame number sent by the network side through the physical layer on the terminal side according to the identifier of the terminal side are as follows: decoding the frame header of the received data frame with the specified frame number through the physical layer on the terminal side to obtain the terminal identifier in the data frame with the specified frame number; when the terminal identifier in the data frame with the specified frame number is consistent with the terminal identifier in the preset message, determining that the data frame with the specified frame number is the data frame that the terminal side should receive; receiving the data frame with the specified frame number sent by the network side.

[0047] Optionally, the specific steps of receiving the data frame with the specified frame number sent by the network side are as follows: reporting the data frame with the specified frame number to the protocol stack on the terminal side through the physical layer; processing the data frame with the specified frame number through the protocol stack to obtain the downlink data.

[0048] When the terminal identifier in the data frame with the specified frame number is inconsistent with the terminal identifier in the preset message, determining that the data frame with the specified frame number does not belong to the data frame that the terminal side should receive; discarding the data frame with the specified frame number through the physical layer.

[0049] It can be understood that after obtaining the identifier of the terminal side included in the preset message, store the identifier of the terminal side included in the preset message through the physical layer.

[0050] As Figure 4 shown, the specific process of receiving downlink data in the embodiments of this application includes:

[0051] Step 1, after the terminal is powered on, it registers to the Tian Tong network, the network assigns a terminal identifier to the terminal, and the terminal protocol stack stores the terminal identifier;

[0052] Step 2, the terminal protocol stack sends the terminal identifier of this terminal to the terminal physical layer;

[0053] Step 3, the terminal physical layer stores the terminal identifier of this terminal;

[0054] Step 4, the terminal listens to the downlink physical channel and receives a downlink data frame;

[0055] Step 5, the physical layer decodes the terminal identifier from the data frame header and matches it with the terminal identifier of this terminal; instead of directly reporting the data frame to the terminal protocol stack;

[0056] Step 6, if the terminal identifier match is successful, the physical layer reports the entire data frame to the terminal protocol stack;

[0057] Step 16, the terminal protocol stack processes this downlink data;

[0058] Step 19, if the terminal identifier match fails, the physical layer discards the data frame.

[0059] Through the above method, when the terminal listens to a large number of downlink channel data frames of non-this terminal, only the physical layer at the bottom layer needs to decode the packet header and discard it, and there is no need to report it to the upper layer protocol stack and no need to wake up the upper layer protocol stack, reducing power consumption.

[0060] In the embodiment of the present application, a downlink data processing method is also proposed, as Figure 5 shown, including:

[0061] Step S502, allocate a Temporary Mobile Subscriber Identity (TMSI) to the terminal side;

[0062] Step S504, perform a modulo operation on the TMSI and a preset value, and determine the data frame with the specified frame number according to the modulo operation result;

[0063] Step S506, send the data frame with the specified frame number to the terminal side only through the data frame with the specified frame number.
