Method of communication link acquisition using search pattern
摘要
說明書
For example, the time of a last location update may be longer than a first maximum threshold time, a time of last detection of the other communication device may be longer than a second maximum threshold time, a level of confidence of being in the same location as the last location update may be lower than a first minimum threshold level of confidence, or a level of confidence of a location of a last received beacon may be lower than a second minimum threshold level of confidence. The first and second maximum threshold time may be, for example, 5 minutes and 10 minutes, respectively, or may both be the same amount of time, such as, for example, 5 minutes. The first and second minimum threshold level of confidence may be, for example, 20% and 10%, respectively, or may both be the same percentage, such as, for example, 10%. The secondary device designation may also be assigned to both the first and second communication device 200a, 200b when the primary and secondary search patterns 700, 800 have been completed without establishing a communication link 22 or when primary and secondary search patterns 700, 800 have been completed after swapping designations without establishing a communication link 22.
