METHOD, DEVICE AND SYSTEM FOR CONTROLLING TUNNEL IDENTIFIER ALLOCATION Russian patent published in 2015 - IPC H04L29/02

Abstract RU 2554558 C2

FIELD: physics, computer engineering.

SUBSTANCE: invention relates to controlling tunnel identifier allocation. The method includes: determining whether the type of the current procedure allows a SGW to change a TEID and/or an Internet Protocol (IP) address (S110); and sending an modify bearer request message to the SGW, wherein the modify bearer request message is used to notify the SGW on whether the SGW is allowed to change the TEID and/or the IP address (S120).

EFFECT: preventing loss of service data packets of a user or service interruption caused by that the serving gateway (SGW) modifies the tunnel endpoint identifier (TEID) and/or the IP address.
