Abstract

Provided are system and method for performing access screening in a CDMA network. In one embodiment, the method comprises comparing a strength of a reference pilot specified in an origination message (“ORM”) received from the mobile unit to at least one of an upper pilot strength threshold (“UPST”) and a lower pilot strength threshold (“LPST”); responsive to the reference pilot strength failing to exceed the LPST, redirecting the mobile unit; responsive to the reference pilot strength exceeding the LPST but failing to exceed the UPST, determining whether an additional pilot is reported having a strength greater than that of the reference pilot; and responsive to a determination that no additional pilot is reported having a strength greater than that of the reference pilot, redirecting the mobile unit.

Claims9

Dependent claims

A base station for a code division multiple access (CDMA) network, the base station comprising:

an RF interface operable to couple the base station to the CDMA network to transmit RF signals to and receive RF signals from the CDMA network, the received RF signals including origination messages;
at least one signal processor coupled to the RF interface and operable:
to compare a reference pilot strength specified in an origination message received from a mobile unit with an upper pilot strength threshold and a lower pilot strength threshold;
to redirect originations when the specified reference pilot strength is between the upper pilot strength threshold and the lower pilot strength threshold and no additional pilot is reported having a strength between the upper pilot strength threshold and the lower pilot strength threshold;
and
to redirect originations when the specified reference pilot strength is below the lower pilot strength threshold.
