Abstract
A method and a mobile device configured, when in idle mode, to select a target frequency from a network in response to a redistribution information from the network, including starting an evaluation timer; performing measurements on a first set of frequencies throughout a duration of the evaluation timer; selecting the target frequency based on the measurements of the first set of frequencies; and starting a second timer, which is distinct from the evaluation timer, during which time the device performs measurements on a second set of frequencies comprising the target frequency.
Claims25
A communication device configured to select a target frequency from a network in response to a redistribution information, comprising:
- a radio frequency transceiver configured to receive a redistribution information from the network;
- a baseband modem configured to:
- trigger an evaluation timer;
- perform measurements on a first set of frequencies throughout a duration of the evaluation timer;
- select the target frequency based on the measurements of the first set of frequencies;
- and
- trigger a second timer, which is distinct from the evaluation timer, during which the communication device performs measurements on a second set of frequencies comprising the target frequency.
A method for a mobile device in idle mode to select a target frequency from a network in response to a redistribution information, comprising:
- starting an evaluation timer;
- performing measurements on a first set of frequencies throughout a duration of the evaluation timer;
- selecting the target frequency based on the measurements of the first set of frequencies;
- and
- starting a second timer, which is distinct from the evaluation timer, during which the mobile device performs measurements on a second set of frequencies comprising the target frequency.
A non-transitory computer readable medium storing instructions thereon that, when executed, cause a processor of a device to perform a selection of a target frequency from a network in response to a redistribution information comprising:
- starting an evaluation timer;
- performing measurements on a first set of frequencies throughout a duration of the evaluation timer;
- selecting the target frequency based on the measurements of the first set of frequencies;
- and
- starting a second timer, which is distinct from the evaluation timer, during which the device performs measurements on a second set of frequencies comprising the target frequency.
