Abstract
Example embodiments described herein are directed towards a PTC node and wireless terminal, and corresponding methods therein, for extended PMR based services. According to some of the example embodiment, through use of a PTC node, a wireless terminal may be simultaneously registered with the public radio access based network and the PMR based network. Thus, a wireless terminal which is not directly connected (or is unable to connect to) a PMR based network may still receive messages originating from the PMR based network.
Claims28
A method, in a Private Mobile Radio, PMR, Tunnelling Controller, PTC, node for extending PMR group communications to a public radio access based network for a wireless terminal, said wireless terminal being served by the public radio access based network and a PMR based network, the method comprising:
- receiving, from a gateway node in the public radio access based network, a registration request originating from the wireless terminal, said registration request comprising identification information for the wireless terminal;
- establishing access with the public radio access based network on behalf of the wireless terminal utilizing said identification information;
- and
- establishing access with the PMR based network on behalf of the wireless terminal utilizing said identification information;
- wherein the establishing further comprises establishing a Virtual Private Network, VPN, tunnelling connection, wherein endpoints of said VPN tunnelling connection are comprised within the wireless terminal and the PTC node.
A Private Mobile Radio, PMR, Tunnelling Controller, PTC, node for extending PMR group communications to a public radio access based network for a wireless terminal, said wireless terminal being served by the public radio access based network and a PMR based network, the PTC node comprising:
- radio circuitry configured to receive, from a gateway node in the public radio access based network, a registration request originating from the wireless terminal, said registration request comprising identification information for the wireless terminal;
- processing circuitry configured to establish access with the public radio access based network on behalf of the wireless terminal utilizing said identification information;
- and
- the processing circuitry further configured to establish access with the PMR based network on behalf of the wireless terminal utilizing said identification information;
- wherein the processing circuitry is further configured to establish a Virtual Private Network, VPN, tunnelling connection, wherein endpoints of said VPN tunnelling connection are comprised within the wireless terminal and the PTC node.
A method, in a wireless terminal, for participating in group communications with a public radio access based network and a Private Mobile Radio, PMR, based network, the method comprising:
- establishing a connection to a serving base station in the public radio access based network;
- sending, to a PMR Tunnelling Controller, PTC, node, a registration request;
- and
- upon registering with the PTC node, receiving a group communication originating from the public radio access based network and the PMR based network through a Virtual Private Network, VPN, tunnelling connection established by the PTC node and having endpoints within the wireless terminal and the PTC node.
A wireless terminal for participating in group communications with a public radio access based network and a Private Mobile Radio, PMR, based network, the wireless terminal comprising:
- processing circuitry configured to establish a connection to a serving base station in the public radio access based network;
- radio circuitry configured to send, to a PMR Tunnelling Controller, PTC, node a registration request;
- and
- upon registering with the PTC node, the radio circuitry configured to receive a group communication originating from the public radio access based network and the PMR based network through a Virtual Private Network, VPN, tunnelling connection established by the PTC node and having endpoints within the wireless terminal and the PTC node.
