Embodiment Construction

[0008] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0009] figure 1 It is the method that the present invention utilizes wireless local area network (WiFi) and Internet voice communication (VoIP) home gateway to GSM mobile communication equipment (VoIP / GSM mobile phone) to realize automatic setting call transfer indoors, adopts the following steps: step 301 is when VoIP / When the GSM mobile phone enters the room, first confirm whether it has entered the basic service group of the wireless LAN. If the result is "No", it will return to the GSM service status; , a host can simultaneously perform identity verification actions with multiple hosts, including access points (APs). In step 102, the mobile phone obtains identity confirmation, and determines that it is already in an indoor wireless local area network. Then proceed to step 103, the VoIP / GSM mobile phone sets call forwarding according to the forwarding s...

Abstract

Present invention discloses mobile communication equipment call transfer method, i.e utilizing wireless local area network ( WiFi ) and speech communication ( VoIP ) home gateway to realize indoor VoIP GSM handset automatically configuring call transfer to public switched telephone network VoIP service. When VoIP / GSM handset entering wireless local area networks basic service, proceeding bidirectional identity confirming, after obtained identity confirming VoIP / GSM proceeding calling to public switched telephone network according to precedence order configuring call transfer and self calling transfer configuration. When after VoIP / GSM handset leaves specifically indoor environment, judging whether leaving local area network basic service group or not, if can not receive VoIP signal in short periods of time, then automatically cancel call transfer and entering GSM service state.

Description

technical field [0001] The present invention relates to a kind of mobile user equipment, especially utilizes IEEE802.11 wireless local area network (WiFi) and Internet voice communication (VoIP) home gateway to let the global digital mobile communication equipment (VoIP / GSM mobile phone) realize automatic setting call forwarding indoors A method of accessing Public Switched Telephone Network (PSTN) services. Background technique [0002] The radiation power of GSM mobile phones is generally between several hundred milliwatts and one watt. Such strong radiation for a long time will cause great damage to the human brain. consumer. Therefore, when the user is at home or in the office, he should try to use a fixed phone or a VoIP phone with a lower cost. At present, some mobile communication operators have launched call forwarding services, but the known call forwarding methods are all manually set, and the user must first apply to the mobile communication operator, and the ma...
