Abstract
To perform an inter-technology handoff, an indicator in a service request message is received by a mobile switching center (MSC). The indicator is to indicate to the MSC that an inter-technology handoff from a packet-data wireless access network to a circuit wireless access network has been requested. The behavior of the MSC is modified in response to the indicator to reduce the communication silence during the inter-technology handoff.
