Problems solved by technology

This approach has significant disadvantages: high power consumption
Since the current Bluetooth module of the extension is running at full power when it initiates a connection and waits for the other party to respond whether it is connected or not, the power consumption of the Bluetooth module is the largest at this time. If the extension initiates registration with the gateway repeatedly, it will quickly The power consumption of the extension is greatly reduced, so that the standby time of the extension is greatly reduced
The probability that the extension is not registered on the gateway due to the extension leaving the gateway or the power failure of the gateway is not low

Embodiment Construction

[0028] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0029] figure 1 is a flowchart of an embodiment of the method of the present invention. As shown in the figure, the method specifically includes the following steps:

[0030] A. Create an extension information list. When an extension is connected to the gateway for the first time and registered to the gateway, the gateway will place the registration information of the extension in the extension information list and monitor it through a process. Once it detects that an extension is in an unregistered state, Then set the "registration flag" of the corresponding extension in the extension information list to "unregistered" and enter step B;

[0031] B. The gateway initiates an active search for the dropped extension;

[0032]C. After the extension is found, the gateway compares it with the information in the extension information list to confirm...

Abstract

The invention discloses a method for recovering the ACL link between a Bluetooth telephone gateway and an extension. By adopting the method / system, the large-extent decrease of the standby duration of the extension due to the processing of recovering the ACL link can be effectively avoided. The system of the invention comprises a gateway and the extension; wherein, the gateway is used for searching for the off-line extension when the extension is disconnected and sending a login request to the off-line extension when the off-line extension is found, so as to complete the registration of the extension; the extension is used for completing the registration process cooperating with the gateway when being found by the gateway after the extension is off line. In the method of the invention, four timers are adopted to manage the method flow; wherein, a cycle timer is used for the cycle management of the whole flow, a searching timer is used for controlling the searching time, a connecting timer is used for controlling the single connection between the gateway and the extension and a dormancy timer is used for the processing in case of failure in connection. The invention requires no change of the hardware, which has the advantage of universality and the meaning of popularization.

Description

technical field [0001] The invention belongs to the technical field of short-distance wireless communication, and in particular relates to a method and a system for restoring an asynchronous connectionless link (ACL, ACL) link between a Bluetooth telephone gateway and an extension. Background technique [0002] Bluetooth is a short-range wireless communication technology that operates in the 2.4GHz ISM (Industrial-Science-Medical) frequency band. The basic network structure of Bluetooth is a wireless micro-network (Piconet) composed of a master device and up to seven slave devices. The master device and slave devices communicate by means of time division multiple access (TDMA). Using Bluetooth technology, various devices can be connected in a low-cost way, such as: Bluetooth phone gateways and Bluetooth phone extensions. [0003] The bluetooth telephone gateway and the bluetooth telephone extension constitute a cordless telephone application environment. Both the cordless ...
