Problems solved by technology

During this time period, if NB-IoT receives a new data request initiated by the user, the RRC layer cannot directly send the message to the network at this time, nor can it initiate a connection establishment request, it will choose to discard the data, and eventually the user data will be sent fail

specific Embodiment 1

[0097] Such as Figure 4 As shown, methods to improve the efficiency of uplink data transmission include:

[0098] Step S401, the RRC layer processing process of the NB-IoT terminal receives radio resource control connection release (RRC connection release) information from the base station, and starts a release timer.

[0099] In a possible implementation manner, the duration of the release timer is 10 seconds.

[0100] Step S402, the NAS layer processing process of the NB-IoT terminal receives the uplink data, and saves the uplink data.

[0101] In step S403, the NAS layer processing process sends a request for transmitting uplink data to the RRC layer processing process.

[0102] In step S404, the RRC layer processing process sends an uplink data transmission failure response to the NAS layer processing process. The response carries the reason for the failure of the uplink data transmission, which is that the RRC connection has been released.

[0103] Step S405 , the re...

specific Embodiment 2

[0112] Such as Figure 5 As shown, methods to improve the efficiency of uplink data transmission include:

[0113] Step S501, the RRC layer processing process of the NB-IoT terminal receives radio resource control connection release (RRC connection release) information from the base station.

[0114] Step S502, the NAS layer processing process of the NB-IoT terminal receives the uplink data, and saves the uplink data.

[0115] In step S503, the NAS layer processing process sends a request for transmitting uplink data to the RRC layer processing process.

[0116] In step S504, the RRC layer processing process sends an uplink data transmission failure response to the NAS layer processing process. The response carries the reason for the failure of the uplink data transmission, which is that the RRC connection has been released.

[0117] Step S505, the RRC layer processing process sends a release acknowledgment (Release ack) instruction.

[0118] In step S506, the RRC layer proc...

Abstract

The invention discloses a method and device for improving uplink data transmission efficiency. The method disclosed by the invention is applied to a narrowband Internet of Things terminal, and comprises the following steps: storing uplink data needing to be sent in a process of converting the narrowband Internet of Things terminal from a connected state to an idle state; and after the narrowband Internet of Things terminal enters the connected state again, sending the uplink data to a network device. The technical scheme disclosed by the invention can ensure that the valid data is not discarded.

Description

technical field [0001] The present invention relates to wireless communication technology, in particular to a method and device for improving uplink data transmission efficiency. Background technique [0002] In the traditional data transmission scheme, it is generally necessary to use the upper computer MCU to preset the service process, and send the service process to the 2G network, and the network performs service transmission according to the requirements of the service process. Due to the high cost of the MCU host computer and complicated wiring, the final operation is often complicated. [0003] NB-IoT is a cellular-based Narrow Band Internet of Things (NB-IoT), which is an important branch of the Internet of Everything. NB-IoT is built on a cellular network and consumes about 180KHz of bandwidth. It can be directly deployed on a GSM network, UMTS network or LTE network, which can reduce deployment costs and achieve smooth upgrades. [0004] The 3GPP protocol stipul...
