US 2019/0104563 A1 · METHOD AND NODES FOR HANDLING BEARERS

Abstract

The embodiments herein relate to a method performed by a gateway (108, 110, 1308, 1310). The gateway (108, 110, 1308, 1310) detects that a procedure for activating or deactivating a bearer has been initiated. The gateway (108, 110, 1308, 1310) receives a first modify bearer or modify access bearers request message for the same PDN connection and UE (101) as the bearer activation or deactivation procedure is intended for. The gateway (108, 110, 1308, 1310) detects a bearer mismatch between a first set of bearers and a second set of bearers known by the gateway (108, 110, 1308, 1310) and associated with said same PDN connection and UE (101). The gateway (108, 110, 1308, 1310) accepts, during a time interval, the received modify bearer or modify access bearers request message even though the bearer mismatch has been detected.

Dependent claims

A method performed by a gateway (108, 110, 1308, 1310) for handling bearers in a communications system (100), the method comprising:

detecting (1402, 1504 1803) that a procedure for activating or deactivating a bearer has been initiated, which bearer is associated with a Packet Data Network, PDN, connection and a User Equipment, UE, (101);
receiving (1404, 1507, 1806) a first modify bearer or modify access bearers request message from a mobility node (105, 1305) for the same PDN connection and UE (101) as the bearer activation or deactivation procedure is intended for, which message identifies a first set of bearers associated with said same PDN connection and UE (101);
detecting (1405, 1807) at least one bearer mismatch between the first set of bearers and a second set of bearers known by the gateway (108, 110, 1308, 1310) and associated with said same PDN connection and UE (101);
accepting (1406, 1808), during a time interval from the procedure has been detected, the received modify bearer or modify access bearers request message even though the bearer mismatch has been detected.

1 more element

A gateway (103, 105) for handling bearers in a communications system (100), the gateway (103, 105) being adapted to:

detect that a procedure for activating or deactivating a bearer has been initiated, which bearer is associated with a Packet Data Network, PDN, connection and a User Equipment, UE, (101);
receive a first modify bearer or modify access bearers request message from a mobility node (105, 1305) for the same PDN connection and UE (101) as the bearer activation or deactivation procedure is intended for, which message identifies a first set of bearers associated with said same PDN connection and UE (101);
detect at least one bearer mismatch between the first set of bearers and a second set of bearers known by the gateway (108, 110, 1308, 1310) and associated with said same PDN connection and UE (101);
and to
accept, during a time interval from the procedure has been detected, the received modify bearer or modify access bearers request message even though the bearer mismatch has been detected.
