Embodiment Construction

[0034] Below we will describe the embodiments of the present invention in detail with reference to the accompanying drawings.

[0035] see figure 1 , which is a flow chart of a method for detecting a data link provided in an embodiment of the present invention, the method includes steps:

[0036] Step 101: Detect the data flow of the GPRS interface; there are many ways to detect it: it can be periodic detection, real-time detection, or a combination of the two, which is not limited in this embodiment.

[0037] Step 102: When it is determined that the data traffic has not changed, send a data message to the GPRS server; wherein, the data message can be a data message in a fixed format, such as sending a fixed message to the GPRS server regularly, in real time, or both interactively. A data message in a fixed format, the data message in a fixed format may be a "heartbeat" signal, but is not limited thereto.

[0038] Step 103: If no response from the GPRS server is received wit...

Abstract

The invention embodiment relates to a detection method and a detection device of a data link. The method comprises the following steps: detecting the data flow of a general packet radio service (GPRS) interface; sending a data message to a GPRS server after confirming that the data flow is not changed; and reestablishing GPRS data connection if not receiving an answering response sent by the GPRS server within a preset time. The invention detects and maintains the GPRS data link by combining a data flow detection method and a heartbeat detection method so as to reduce an invalid data flow and network blockage at terminals and improve the detection efficiency.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a data link detection method and device. Background technique [0002] With the development of communication technology, when using General Packet Radio Service (GPRS, General Packet Radio Service) to communicate, in order to maintain the data connection and ensure that the GPRS terminal is always online, the GPRS terminal and the GPRS server usually use "heartbeat" detection to maintain the GPRS connection link. Among them, the "heartbeat" detection has two functions: one is to detect the online status of the GPRS server, and judge the normal state of the GPRS data link; the other is to notify the GPRS server that "the GPRS terminal is still Online, please don't hang up." [0003] That is to say, the GPRS terminal periodically sends fixed-format messages (usually referred to as heartbeat signals) to the GPRS server. When the signal reaches a certain number, the GPRS te...
