METHOD FOR SOURCE CORE NETWORK NODE, SOURCE CORE NETWORK NODE, AND NON-TRANSITORY COMPUTER-READABLE MEDIUM: abstract simplified (18012464)

• This abstract for appeared for patent application number 18012464 Titled 'METHOD FOR SOURCE CORE NETWORK NODE, SOURCE CORE NETWORK NODE, AND NON-TRANSITORY COMPUTER-READABLE MEDIUM'

Simplified Explanation

This abstract describes a method for managing user data control in a network. The method involves receiving a message to cancel the handover of a terminal from one network to another, transmitting messages between different network nodes, and releasing a secured resource in a core network device.

Original Abstract Submitted

An object is to appropriately manage a resource for user data control. A method for a source core network node according to one aspect of the present disclosure, includes: receiving, from a source RAN associated with a 5GS, a first message for canceling handover of a terminal from the 5GS to an EPS; transmitting a second message to a target core network node associated with the EPS when receiving the first message; receiving a third message from the target core network node when transmitting the second message; transmitting a fourth message to the source RAN when receiving the third message; and transmitting a fifth message for releasing a resource being secured in a core network device when transmitting the fourth message.
