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.
Claims21
-16. (canceled)
method of operating when handing off a mobile device between different types of wireless access networks, comprising:
- determining that a mobile device should be handed off from a packet data wireless access network to a circuit wireless access network;
- in response to the determining, delaying sending a message that commands a node to send a handoff message to the mobile device to perform the handoff until after a predetermined trigger has occurred;
- and
- sending the message that commands the node to send a handoff message to the mobile device after the predetermined trigger has occurred, wherein the message comprises a 1x handoff direction message.
A node, comprising:
- communication circuitry;
- and
- processing hardware coupled to the communication circuitry, wherein the processing hardware and the communication circuitry are configured to operate together to:
- determine that a mobile device should be handed off from a packet data wireless access network to a circuit wireless access network;
- in response to the determining, delay sending a message that commands a node to send a handoff message to the mobile device to perform the handoff until after a predetermined trigger has occurred;
- and
- send the message that commands the node to send a handoff message to the mobile device after the predetermined trigger has occurred, wherein the message comprises a 1x handoff direction message.
A non-transitory, computer accessible memory medium storing program instructions executable by a processor to:
- determine that a mobile device should be handed off from a packet data wireless access network to a circuit wireless access network;
- in response to the determining, delay sending a message that commands a node to send a handoff message to the mobile device to perform the handoff until after a predetermined trigger has occurred;
- and
- send the message that commands the node to send a handoff message to the mobile device after the predetermined trigger has occurred, wherein the message comprises a 1x handoff direction message.
