High-speed mobility communication systems and methods

A communication device adapted for communicating in a communication system, the communication device comprising:

• a transceiver configured to communicate with first and second communication networks;
• and
• a controller coupled to the transceiver and configured to:
• determine a mobility status of the communication device;
• adjust a cell order of cells of the first and the second communication networks, based on a signal characteristic of the cells of the first and the second networks and the mobility status of the communication device, to generate a prioritized cell list;
• and
• select, based on the prioritized cell list, a cell corresponding to the first communication network to establish a communication using the selected cell of the first communication network.

A communication device adapted for communicating in a communication system, the communication device comprising:

• a transceiver configured to communicate with first and second communication networks, the first and the second communication networks each including a main network and fallback network;
• and
• a controller coupled to the transceiver and configured to:
• determine a mobility status of the communication device;
• receive release information from the first communication network using the transceiver, the release information lacking redirection information;
• prioritize cells of the fallback network of the first communication network over cells of the second communication network within a cell list, based on the mobility status and a signal characteristic of the cells of the fallback network of the first communication network while ignoring system information of the cells of the fallback network of the first communication network, to generate a prioritized cell list;
• and
• select, based on the prioritized cell list, a cell of the fallback network of the first communication network to establish a communication on the selected cell.

A method for performing wireless communication by a communication device in a communication system including first and second communication networks, the first and the second communication networks each including a main network and fallback network, the method comprising:

• determining a mobility status of the communication device;
• receiving release information from the first communication network in response to a request to initiate a fallback communication, the release information lacking redirection information;
• prioritizing cells of the fallback network of the first communication network over cells of the second communication network, based on the mobility status and a signal characteristic of the cells of the fallback network of the first communication network while ignoring system information of the cells of the fallback network of the first communication network, to generate a prioritized cell list;
• and
• selecting, based on the prioritized cell list, a cell of the fallback network of the first communication network to establish the fallback communication on the selected cell.
