Problems solved by technology

[0008] Although the amount of data reported by the MTC device is very small each time, it also requires a complete set of connection establishment and bearer establishment procedures. In this way, the amount of signaling data accounts for a very large proportion of the total air interface communication data amount, and the transmission efficiency is low.
[0009] In addition, due to the large number of MTC devices, each MTC device needs to perform random access when accessing, which will occupy a large amount of random access resources, resulting in an increase in the collision probability of random access and affecting the communication experience of other normal terminals.

Embodiment 1

[0032] Embodiment 1 of the present invention provides a method for transmitting data, such as figure 2 , including the following.

[0033] 20. The device receives the paging message.

[0034] When the base station needs to trigger the device to report user data, it sends a paging message to the device, and the paging message includes a list of terminals that need to be paged.

[0035] 21. The above-mentioned device determines an opportunity to acquire an uplink transmission resource based on the subframe in which the paging message is received.

[0036] Wherein, based on the subframe in which the above paging message is received, determining the timing of acquiring uplink transmission resources includes:

[0037] 1) When the above-mentioned device is an MTC device, the above-mentioned timing for acquiring uplink transmission resources=the subframe of the above-mentioned paging message or the subframe indicated by the above-mentioned paging message+fixed offset+K*the index n...

example 1

[0055] The scenario is: eNB needs to trigger a group of MTC devices to report data, and send a paging message at a certain paging time. In this example, the paging message contains a list of two MTC devices (MTC device 1 and MTC device 2) as an example , the process of MTC device reporting data is as follows image 3 , including the following.

[0056] 30. After receiving the paging message, each MTC device calculates its target subframe respectively according to the subframe in which the paging message is received and its position in the paging list, that is, determines the timing for acquiring uplink transmission resources.

[0057] In this embodiment, the method for the MTC device to determine the timing of acquiring uplink transmission resources is as follows: the subframe where the above paging message is located can be used as a reference, and a fixed value is added, and then according to the position of each MTC device in the paging list, sequentially analogy. For exa...

example 2

[0066] The eNB needs to trigger a group of MTC devices to report data and send a paging message at a certain paging time. In this example, the paging message contains a list of two terminals (MTC device 1 and MTC device 2). This example is It saves PDCCH resources, simplifies air interface messages, and adopts a method of scheduling once and transmitting multiple times. Such as Figure 4 As shown, the process of the MTC device reporting data specifically includes the following contents.

[0067] 40. After receiving the above paging message, if the MTC device finds itself in the paging list, it uses the subframe of the paging message as a reference, and after a fixed time interval, obtains the PDCCH message of the base station to obtain uplink transmission resources. That is, based on the subframe of the paging message, the timing after a fixed time interval is used as the timing for acquiring the uplink transmission resource.

[0068] The aforementioned fixed time interval m...

Abstract

The invention provides a method for transmitting data in the field of communication. The method comprises the following steps that: equipment receives a page message and determines the timing of acquiring uplink transmission resources by utilizing a subframe which receives the page massage as reference; the equipment acquires the uplink transmission resources at the timing of acquiring the uplink transmission resources; and the equipment reports user data in the uplink transmission resources by utilizing timing advance which is stored in the equipment and is corresponding to the current position. The embodiment of the invention further provides equipment for transmitting data. By utilizing the method and the equipment provided by the embodiment of the invention, MTC (Magnetic Tape controller) equipment can transmit uplink data without performing random access and establishing an RRC (Radio Resource Control) connection and a user interface carrier, so that the data transmission process of the equipment is greatly simplified, the equipment can rapidly and efficiently transmit the uplink data, the transmission efficiency is improved, and the signaling load of a base station is lightened.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and device for transmitting data. Background technique [0002] M2M (Machine-to-Machine, device-to-device) is a technology to realize direct communication between devices. Its goal is to enable all machines and devices to have networking and communication capabilities. Therefore, M2M technology has very important significance and broad markets and applications. [0003] At present, most M2M devices are fixed, do not move frequently, and their communication volume is not high, and the number of times of data transmission is not much, such as electric meters, water meters and other devices, only need to report data once a month through the wireless network. The amount of data transferred at a time is also small. However, due to the large absolute number of M2M devices, how to manage the communication between so many M2M devices and the wireless network has...
