Gateway device for wireless networks
This document discloses a solution for connecting wireless networks. According to an aspect, a method comprises: establishing, by a gateway device, a first physical layer connection with a first device of a two-way radio network operating according to a two-way radio network protocol, establishing, by the gateway device, a second physical layer connection with a second device of a wireless network operating according to a wireless communication protocol different from the two-way radio network protocol; and connecting, by the gateway device, a communication connection established between the second device and the wireless network to the first device through the first physical layer connection and the second physical layer connection.
1. A method for connecting wireless networks, the method comprising:
establishing, by a gateway device, a first physical layer connection with a first device of a two-way radio network operating according to a two-way radio network protocol,
establishing, by the gateway device, a second physical layer connection with a second device of a wireless network operating according to a wireless communication protocol different from the two-way radio network protocol; and
connecting, by the gateway device, a full duplex communication connection established between the second device and the wireless network to the first device through the first physical layer connection and the second physical layer connection and performing, by the gateway device, adaptation between the full duplex communication connection and half duplex communication of the two-way radio network,
wherein the gateway device is an accessory device of at least one of the first device and the second device.
2. The method of claim 1 , wherein said performing the adaptation comprises as performed by the gateway device:
receiving a push-to-talk request from one of the first device and the second device;
adapting the push-to-talk request for the other one of the first device and the second device and transmitting the adapted push-to-talk request to the other one of the first device and the second device;
receiving, from the other one of the first device and the second device, a push-to-talk grant message; and
adapting the push-to-talk grant message for the one of the first device and the second device and transmitting the adapted push-to-talk grant message to the one of the first device and the second device.
3. The method of claim 1 , wherein first physical layer connection and the second physical layer connection are wired connections.
4. The method of claim 3 , wherein the gateway device is integrated into a cable connecting the first device and the second device.
5. The method of claim 1 , further comprising:
receiving, by the gateway device, digital non-voice data of the communication connection from the second physical layer connection; and
converting, by the gateway device, the digital non-voice data and transmitting the converted non-voice data to the first physical layer connection.
6. The method of claim 1 , further comprising:
receiving, by the gateway device, an AT command from the second device over the second physical layer connection; and
extracting the AT command and performing, by the gateway device, a function instructed by the AT command.
7. The method of claim 1 , further comprising by the gateway device:
providing, by the gateway device, a device-to-device communication connection between the first device and the second device while neither the first device nor the second device is connected to a base station of the respective network.
8. A gateway device comprising:
a first interface configured to provide a first physical layer connection with a first device of a two-way radio network operating according to a two-way radio network protocol,
a second interface configured to provide a second physical layer connection with a second device of a wireless network operating according to a wireless communication protocol different from the two-way radio network protocol; and
processing circuitry configured to connect a full duplex communication connection established between the second device and the wireless network to the first device through the first physical layer connection and the second physical layer connection and to perform adaptation between the full duplex communication connection and half duplex communication of the two-way radio network,
wherein the gateway device is an accessory device of at least one of the first device and the second device.
9. The gateway device of claim 8 , further comprising audio conversion circuitry configured to perform audio conversion between the first physical layer connection and the second physical layer connection.
10. The gateway device of claim 9 , wherein the audio conversion circuitry is configured to output an audio signal received from one of the first physical layer connection and the second physical layer connection and output the audio signal in a converted form to the other one of the first physical layer connection and the second physical layer connection, and further configured to output audio signal in a converted form to an audio speaker of the gateway device.
11. The method of claim 8 , wherein the gateway device is integrated into a cable configured to connect the first device and the second device.
