Claim Text:
1. A device access method, wherein the method comprises: generating, by an access point, a broadcast frame, wherein the broadcast frame comprises a feature identifier of an access device paged by the access point and includes a length (L) of a contention service period, and sending, by the access point, the broadcast frame to the access device, to enable the access device in the broadcast frame to access the access point within the contention service period; wherein the length (L) of the contention service period is linearly proportional to a product of a timeslot (tslot) for the access device to connect through a contention and a value (N) of a greatest number of backoff windows; wherein the contention service period is used to enable the access device which corresponds to a unique equipment identifier in the broadcast frame to access the access point by means of through contention in the contention service period; wherein a maximum time duration of the backoff windows equals N*tslot where the value N equals −1 and the length (L) of the contention service period equals b*N*tslot; wherein n denotes a quantity of access devices that are paged by the access point and comprised in the broadcast frame; a is a constant greater than 1; b is a constant greater than 1; and denotes rounding down.
