description The present invention provides a method for obtaining a monitoring frequency channel number, and an access terminal. The method includes: when an Evolution-Data Optimized session of an access terminal is in a closed state or in an initialization process, and when a first expected frequency channel number obtained by the access terminal according to a first session seed and a first sector parameters message is different from a current frequency channel number of a signal currently received by a access terminal, generating, by the access terminal, a second session seed different from the first session seed, where N is a positive integer, and a monitoring frequency channel number of the access terminal is a current monitoring frequency channel number; receiving, by the access terminal, a second sector parameters message; obtaining, by the access terminal, a second expected frequency channel number according to the second sector parameters message, the second session seed, and a non-coherence parameter; and using, by the access terminal, the second expected frequency channel number as the monitoring frequency channel number when the second expected frequency channel number is the same as the current frequency channel number. According to the foregoing technical solutions, a technical problem in the prior art of EVDO service unavailability caused by a failure to switch a monitoring frequency channel number is resolved.
