A method of determining the direction of a mobile communication device, the method comprising receiving an encoded locator signal from the device over a wireless link; decoding the locator signal to generate a decoded output; and measuring the direction of arrival of the locator signal by analyzing the decoded output. A method of maintaining a connection with a mobile communication device, the method comprising establishing a connection with the device; receiving a request from the device to release the connection; and repeatedly sending a request for information to the device to prevent the device from releasing the connection. A method of maintaining communication with a mobile cellular communication device, the method comprising establishing a connection with the device by broadcasting a first cell configured with a first location code to the device; and re-establishing the connection with the device after the device has released the connection by broadcasting a second cell configured with a second location code to the device.
A method of maintaining a connection between a separately introduced device and a mobile communication device registered with a network which has performed authentication and integrity procedures that ensure that the mobile communication device is confident that the network is legitimate and the network is confident that the mobile communication device is legitimate, the method comprising:
A method of maintaining communication between a separately introduced device and a mobile cellular communication device registered with a network, the method comprising:
A non-transitory computer readable medium embodied with a computer program product having instructions embedded thereon which, when executed by a processor, causes a separately introduced device not registered with a network to perform the following steps:
A separately introduced device configured to maintain communication with a mobile cellular communication device, the separately introduced device not being registered with a network and the mobile cellular communication device being registered with the network, wherein comprising:
