Abstract
A method includes storing in a mobile communication terminal a definition of a set of frequency bands in which the terminal is capable of communicating, including at least first and second frequency bands. One or more combinations of at least portions of the frequency bands in the set, which cannot be allocated in proximity to one another due to interference, are determined in the terminal. A search is conducted in the terminal over the set of the frequency bands. Upon detecting a presence of a candidate wireless network in a first portion of the first frequency band, which cannot be allocated in proximity to at least a second portion of the second frequency band in accordance with the specification, at least the second portion is omitted from the search.
Claims20
A method for communication, comprising:
- storing in a mobile communication terminal a definition of a set of frequency bands in which the terminal is configured to communicate, including at least first and second frequency bands;
- determining in the terminal one or more combinations of at least portions of the frequency bands in the set that cannot be allocated in proximity to one another due to interference;
- conducting in the terminal a search over the set of the frequency bands;
- and
- upon detecting a presence of a candidate wireless network in a first portion of the first frequency band, which cannot be allocated in proximity to at least a second portion of the second frequency band in accordance with the specification, omitting at least the second portion from the search.
A communication apparatus, comprising:
- a transceiver, which is configured to communicate with wireless networks;
- and
- a processor, which is configured to store a definition of a set of frequency bands in which the transceiver is configured to communicate, including at least first and second frequency bands, to determine one or more combinations of at least portions of the frequency bands in the set that cannot be allocated in proximity to one another due to interference, to conduct using the transceiver a search over the set of the frequency bands, and, upon detecting a presence of a candidate wireless network in a first portion of the first frequency band, which cannot be allocated in proximity to at least a second portion of the second frequency band in accordance with the specification, to omit at least the second portion from the search.
