Problems solved by technology

[0010] In the prior art, the network judges whether the wireless link fails by configuring periodic uplink resources and testing their quality. However, limited by the available resources in the actual system, it cannot guarantee that periodic configuration is performed for each connected user. Uplink resources, or even if periodic uplink resources are configured, if the user enters the uplink out-of-sync state without data transmission and reception for a long time, the periodic uplink resources will be released automatically, that is, the existing technology cannot effectively detect the terminal link quality

Embodiment 1

[0031] Embodiment 1 of the present invention provides a wireless link failure processing method to detect the wireless link of the terminal, wherein the network side can detect the terminal link status in real time, or detect the terminal link status in a triggered manner. Status, for example, only when data needs to be sent and received, the terminal link status is triggered to be detected. Such as image 3 As shown, the method includes the following steps:

[0032] In step 301, the network side requests the terminal to send an uplink signal by presetting a first period (for example, period T1), and performs a first signal quality detection.

[0033] Among them, (1) the network side can detect whether the terminal is in the uplink synchronization state, and when the terminal is not in the uplink synchronization state, request the terminal to send an uplink signal through the preset first cycle; (2) the network side can detect whether the terminal is configured with a cycle ...

Embodiment 2

[0046] Embodiment 2 of the present invention provides a wireless link failure processing method, such as Figure 4 As shown, the method includes the following steps:

[0047] Step 401, the network side judges whether the terminal is in the uplink synchronization state, if yes, execute step 402, otherwise, execute step 405.

[0048] Step 402, the network side judges whether the terminal is configured with periodic uplink resources, if yes, execute step 403, otherwise, execute step 405.

[0049] The periodic uplink resource may be an uplink sounding reference symbol SRS (Sounding Reference Symbol, sounding reference symbol) or an uplink dedicated resource used by the terminal to feed back downlink channel quality information (for the LTE system, it is a PUCCH resource).

[0050] Step 403, the network side detects the signal quality of the periodic uplink resource of the terminal.

[0051] Step 404, the network side judges whether the signal quality of the periodic uplink resou...

Embodiment 3

[0062] Based on the same inventive concept as the above method, Embodiment 3 of the present invention also provides a network side device, such as Figure 5 As shown, the equipment includes:

[0063] The first processing module 11 is configured to request the terminal to send an uplink signal through a preset first cycle, and perform a first signal quality detection;

[0064] The second processing module 12 is configured to request the terminal to send an uplink signal through a preset second cycle if the first signal quality is detected to be lower than the preset first threshold within the first preset number of consecutive times, and perform a second signal quality Detection; the preset second cycle is greater than the preset first cycle;

[0065] The third processing module 13 is configured to release network resources corresponding to the uplink wireless link if it is determined according to the second signal quality that the recovery of the uplink wireless link of the t...

Abstract

The invention discloses a method and equipment for processing radio link failure. The method comprises the following steps that: a network side requires a terminal to send an uplink signal by presetting a first cycle, and detects the quality of a first signal; if the quality of the first signal is continuously lower than a first preset threshold in the first time, the network side requires the terminal to send the uplink signal by presetting a second cycle, and detects the quality of a second signal; and if the uplink radio link recovery of the terminal fails according to the quality of the second signal, the network side releases a network resource corresponding to the uplink radio link. In the embodiment of the invention, the network side actively requires the terminal to send the uplink signal and detects the quality of the signals so as to accurately acquire the radio link state of the terminal, solve the problem of judging the link state of the terminal, effectively avoid maloperation caused by error judgment, and improve the reliability of the system.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a method and equipment for processing wireless link failure. Background technique [0002] Such as figure 1 As shown, in the cellular mobile communication system, the communication link on the wireless side is divided into two directions: uplink and downlink. The downlink is the link for the base station to send data to the terminal, and the uplink is the link for the terminal to send data to the base station. The following takes the LTE (Long Term Evolution, long-term evolution) system as an example to illustrate the communication process between the terminal and the network and the link state detection process. [0003] In the LTE system, when a terminal needs to initiate a service, the terminal first establishes a communication connection with the network, then sends uplink data through uplink radio resources, and receives downlink data through downlink radio re...
