A method and system for providing seamless mobile IP connectivity between mobile stations (MS) connected to a PCS network via base stations (HS) connected to base station switching centers (BSCs). The BSCs are connected to a mobile station switching station (MSC) and are configured to direct voice traffic from the MS to the MSC. A gateway muter (GR) is connected between the BSCs and the Internet and each BSC is configured as an IP data node. One or more subsets are defined, each of which includes at least one BSC. Each MS is assigned a permanent IP address and associated with a home subset. When the system detects that the MS is connected to a BSC outside of its home subset, it is assigned a care-of address to the MS to which IP data can be forwarded. IP data from the MS is muted though the GR. IP data directed to the MS is directed to the MS's permanent IP address. If the MS is connected to a BSC outside of its home subset, the data tragic is forwarded to the MS's care-of address. A mobile station and base station controller for use in such a network is also presented.
