Abstract
A system in which a wireless communication device (e.g. a NB-IoT device) can obtain assistance information from a location server which can help the WCD select the right target RAT. A method performed by a wireless communication device, the method comprising: receiving inter-Radio Access Technology (inter-RAT) assistance information; determining a RAT based on the received inter-RAT assistance information; and utilizing the determined RAT.
Claims25
A method performed by a wireless communication device for determining a suitable Radio Access Technology (RAT), the method comprising:
- receiving a first indication, transmitted by a network node, indicating that the network node is capable of inter-RAT support, wherein the network node is one of a server and a radio access node;
- transmitting an inter-RAT assistance request to the network node;
- receiving a request for location information of the wireless communication device;
- determining the location information of the wireless communication device at a current location of the wireless communication device;
- transmitting the location information;
- receiving inter-RAT assistance information;
- determining a RAT based on the received inter-RAT assistance information;
- and
- utilizing the determined RAT.
A method performed by a server, the method comprising:
- receiving a request for inter-Radio Access Technology (inter-RAT) assistance for a wireless communication device;
- obtaining location information of the wireless communication device;
- determining inter-RAT assistance information for the wireless communication device based on the obtained location information;
- and
- transmitting the determined inter-RAT assistance information.
A wireless communication device, the wireless communication device comprising:
- communication circuitry;
- and
- processing circuitry configured to:
- receive a first indication, transmitted by a network node, indicating that the network node is capable of inter-Radio Access Technology (inter-RAT) support, wherein the network node is one of a server and a radio access node;
- transmit an inter-RAT assistance request to the network node;
- receive a request for location information of the wireless communication device;
- determine the location information of the wireless communication device at a current location of the wireless communication device;
- transmit the location information;
- receive inter-RAT assistance information;
- determine a RAT based on the received inter-RAT assistance information;
- and
- utilize the determined RAT.
A server comprising:
- a network interface;
- and
- processing circuitry configured to:
- receive a request for inter-Radio Access Technology, inter-RAT, assistance for a wireless communication device;
- obtain location information of the wireless communication device;
- determine inter-RAT assistance information for the wireless communication device based on the obtained location information;
- and
- transmit the determined inter-RAT assistance information.
