View Patent ↗This method for changing the radio access point associated with a terminal, within a Wi-Fi-DECT wireless telecommunication network comprising dual-mode Wi-Fi-DECT radio terminals (PP) and Wi-Fi-DECT radio access points (AP 1 , AP 2 ) connected to a local area network; comprises a step consisting of changing the Wi-Fi-DECT radio access point for the Wi-Fi part of the terminal in question (PP) whenever it is decided to change the Wi-Fi-DECT radio access point for the DECT part of the terminal in question (PP).
1. A method for changing the radio access point associated with a dual mode Wi-Fi-DECT radio terminal, within a Wi-Fi-DECT wireless telecommunications network comprising dual-mode Wi-Fi-DECT radio terminals and dual-mode Wi-Fi-DECT radio access points connected to a local area network; comprising the following in order to change the dual-mode radio access point associated with a dual mode Wi-Fi-DECT radio terminal, when a first Wi-Fi mode link and a first DECT mode link have been established between that dual mode Wi-Fi-DECT radio terminal and a first dual-mode Wi-Fi-DECT radio access point:
a second dual-mode Wi-Fi-DECT access point applying a known method for deciding on and executing a change of the radio access point associated with that dual mode Wi-Fi-DECT radio terminal for a first DECT mode link, in order to switch the DECT part of that first dual-mode Wi-Fi-DECT access point to the DECT part of said second dual-mode Wi-Fi-DECT access point;
and said second dual-mode Wi-Fi-DECT access point transferring the first Wi-Fi mode link from the Wi-Fi part of that first dual-mode Wi-Fi-DECT access point to the Wi-Fi part of that second dual-mode Wi-Fi-DECT access point, whenever it decides to change the radio access point associated with that dual mode Wi-Fi-DECT radio terminal for the first DECT mode link, from that first dual-mode Wi-Fi-DECT access point to that second dual-mode Wi-Fi-DECT access point.
2. A method according to claim 1 , wherein, in order to transfer the first Wi-Fi mode link from that first dual-mode Wi-Fi-DECT access point to that second dual-mode Wi-Fi-DECT access point, it comprises:
preserving two links, established in a fixed-line network, connected to the first dual-mode Wi-Fi-DECT access point and respectively coupled to the DECT mode link and to the Wi-Fi mode link;
and relaying these two links by respectively establishing two new links between the first dual-mode Wi-Fi-DECT access point and the second dual-mode Wi-Fi-DECT access point in the fixed-line network.
3. A method according to claim 1 , further consisting of replacing a Wi-Fi data transmission link with a DECT data transmission link whenever that Wi-Fi link is interrupted, until a Wi-Fi data transmission link can be established again.
4. A dual-mode Wi-Fi-DECT access point, for a Wi-Fi-DECT wireless telecommunication network, comprising dual mode Wi-Fi-DECT radio terminals and dual-mode Wi-Fi-DECT radio access points, wherein it comprises:—a DECT part and a Wi-Fi part for simultaneously establishing a first DECT mode link and a first Wi-Fi mode link with a dual mode Wi-Fi-DECT radio mobile terminal;—a control module to apply a known method for changing the radio access point associated with a dual mode Wi-Fi-DECT radio terminal, for a first DECT mode link, to switch from the DECT part of said dual-mode Wi-Fi-DECT access point to the DECT part of a second dual-mode Wi-Fi-DECT access point,
and a control module to transfer the first Wi-Fi mode link from the Wi-Fi part of said dual-mode Wi-Fi-DECT access point to the Wi-Fi part of said second dual-mode Wi-Fi-DECT access point, whenever it is decided to transfer the first DECT mode link from said dual-mode Wi-Fi-DECT access point to that second dual-mode Wi-Fi-DECT access point.
5. A dual-mode Wi-Fi-DECT access point, according to claim 4 , wherein the control module for transferring the first Wi-Fi mode link from that first dual-mode Wi-Fi-DECT access point to a second dual-mode Wi-Fi-DECT access point, comprises a training module for:
preserving two links, established in a fixed-line network, connected to the first dual-mode Wi-Fi-DECT access point and respectively coupled to the DECT mode link and to the Wi-Fi mode link;
and relaying these two links by respectively establishing two new links between the first dual-mode Wi-Fi-DECT access point and the second dual-mode Wi-Fi-DECT access point in the fixed-line network.
6. A dual-mode Wi-Fi-DECT access point, according to claim 4 , further comprising a control module for replacing a Wi-Fi data transmission link with a DECT data transmission link whenever that Wi-Fi link is interrupted, until a Wi-Fi data transmission link can be established again.
