ABSTRACT:
A method and system are disclosed where both a mobile station (105) and the infrastructure logically treat all access probes of an access attempt as if they were transmitted to a first base station (101). This is accomplished by having the mobile station (105) store both the registration parameters received from the first base station (101) to which an access probe is transmitted and a characteristic, such as the PN offset, of the first base station (101). When the mobile station (105) determines that it should perform an access probe handoff, it transmits an access probe to a different base station, identifying in the probe the characteristic, such as the PN offset, of the first base station (101). This allows the infrastructure to identify the base station that the mobile station (105) intends to register with. When the mobile station (105) receives acknowledgment to the access attempt, it then updates its registration variables with respect to the parameters received from the first base station (101).
