Method and device for short-range communication

Abstract

A method for data transmission in a wireless local area network (WLAN) is proposed, comprising the following steps: a short-haul communication chip of a first communication device receives a message sent by a first port of a second communication device through a receiver, and the short-haul communication chip determines whether the first port belongs to a set of ports according to the information of the first port; the set of ports is a set of ports allowing transmission of messages to the first communications device; if the short-haul communications chip determines that the first port does not belong to the set of ports, the short-haul communication chip prohibits transmission of the message to a master chip of the first communication device; and if the short-haul communication chip determines that the first port belongs to the set of ports, the short-haul communication chip sends the message to the master chip. As a result, since the WLAN device recognizes and filters the remote ports that carry out WLAN transmission with the WLAN device, the power consumption of the WLAN device is reduced.

Description

technical field [0001] The invention relates to the field of communication, in particular to a method and device for short-distance communication in a wireless local area network in the field of communication. Background technique [0002] In a short-distance communication technology, such as a traditional wireless local area network (Wireless Local Area Networks, "WLAN") networking, WLAN devices can be divided into two types, namely access points (Access Point, "AP") and stations ( Station, referred to as "STA"). This classification will not cause any problems when mobile terminals such as notebooks and mobile phones are used as the main STA. Because all these devices have a common feature, access each other or access the Internet through the AP. [0003] With the rise of the Wireless Fidelity (Wireless Fidelity, "WIFI" for short) Internet of Things, devices of various types of services appear in the WLAN, such as Internet of Things devices such as refrigerators, washing ...

AI Technical Summary

Problems solved by technology

Since it is sleeping most of the time, it is susceptible to increased power consumption due to data from other devices in the network

[0004] In addition, in the scene of a digital video camera (Digital Video, referred to as "DV"), although the DV acts as an AP, it cannot provide the service of accessing the Internet.

If the mobile phone still sends a large amount of Hyper Text Transfer Protocol (HTTP) or Domain Name System (Domain Name System, DNS) data, it will not only increase the power consumption of the mobile phone itself, but also increase the DV power consumption
