Abstract
The embodiments herein relate to a method performed by a gateway. The gateway detects that a procedure for activating or deactivating a bearer has been initiated. The gateway receives a first modify bearer or modify access bearers request message for the same PDN connection and UE as the bearer activation or deactivation procedure is intended for. The gateway detects a bearer mismatch between a first set of bearers and a second set of bearers known by the gateway and associated with said same PDN connection and UE. The gateway accepts, during a time interval, the received modify bearer or modify access bearers request message even though the bearer mismatch has been detected.
Claims25
A method performed by a gateway for handling bearers in a communications system, the method comprising:
- detecting that a procedure for activating or deactivating a bearer has been initiated, wherein the bearer is associated with a network connection and a User Equipment (UE);
- receiving a first bearer modification request message, wherein the first bearer modification request message identifies a first set of one or more bearers associated with the network connection and the UE;
- detecting a first bearer mismatch between the first set of bearers and a second set of one or more bearers associated with the network connection and the UE;
- determining whether a condition is satisfied, wherein determining whether the condition is satisfied comprises determining whether the first bearer mismatch was detected during a particular time interval;
- and
- as a result of determining that the condition is satisfied, accepting the received bearer modification request message even though the first bearer mismatch has been detected.
A gateway for handling bearers in a communications system, the gateway comprising:
- a memory;
- and
- processing circuitry coupled to the memory, wherein the gateway is adapted to:
- detect that a procedure for activating or deactivating a bearer has been initiated, wherein the bearer is associated with a network connection and a User Equipment (UE);
- receive a first bearer modification request message, wherein the first bearer modification request message identifies a first set of bearers associated with the network connection and the UE;
- detect a first bearer mismatch between the first set of bearers and a second set of bearers associated with the network connection and the UE;
- determine whether a condition is satisfied, wherein the gateway is configured to determine whether the condition is satisfied by performing a process that comprises determining whether the first bearer mismatch was detected during a particular time interval;
- and
- as a result of determining that the condition is satisfied, accept the received bearer modification request message even though the first bearer mismatch has been detected.
