Claim:
A method for use in a scenario where a user equipment is moving within a coverage of a first network and a second network, wherein the user equipment is registered with both a first access entity of the first network and a second access entity of the second network, and a first association is established between the first access entity and the second access entity so that when the user equipment needs to be paged, the user equipment is paged in a paging area administered by the first access entity and a paging area administered by the second access entity according to the first association, and the method comprises: receiving, by a third access entity of the second network, a location update request sent from the user equipment; acquiring, by the third access entity, information of the first access entity from the location update request; and determining, by the third access entity, whether a predetermined condition is satisfied, wherein if the predetermined condition is not satisfied, when the user equipment needs to be paged, the paging of the user equipment through the first access entity in the paging area administered by the first access entity is allowed, and if the predetermined condition is satisfied, when the user equipment needs to be paged, the paging of the user equipment through the first access entity in the paging area administered by the first access entity is prohibited, and wherein the predetermined condition comprises one or more of the following: a distance between an area where the user equipment is currently located and the paging area administered by the first access entity exceeds a predetermined threshold; the third access entity cannot be associated with the first access entity; and the speed of the user equipment in a current access entity system is lower than a threshold.
