METHOD, NETWORK SYSTEM AND DESTINATION NETWORK FOR TRANSMITTING QOS DURING A HANDOVER PROCESS BETWEEN SYSTEMS

摘要

A method for transmitting QoS during handover between systems and network system and destination network thereof enable a user terminal to transmit Q oS to a second network access network during handover between systems. The m ethod of the present invention includes: a second network mobility managemen t network unit acquires service quality parameter QoS of a user terminal dur ing the user terminal handover from a first network to a second network; and the second network mobility management network unit transmits the acquired QoS to the second network access network and/or a user panel network unit. T he system of the present invention includes:a user terminal, a first network and a second network, the second network includes: a second network mobilit y management network unit and a second network access network; the second ne twork mobility management network unit is used for acquiring service quality parameter QoS of a user terminal during the user terminal handover from a f irst network to a second network, and transmits the QoS to the second networ k access network; the second network access network is used for receiving th e transmitted QoS from the second network mobility management network unit.
