Method and apparatus for handling redundant protocol data unit sessions in a communication system

A method comprising:

• establishing at least two redundant protocol data unit sessions to at least one user equipment, wherein the at least two redundant protocol data unit sessions are established based on dual connectivity in a radio access network;
• collecting network status information related to the at least two redundant protocol data unit sessions;
• configuring a set of protocol data unit session switching patterns for the at least two redundant protocol data unit sessions based on the network status information;
• and
• causing transmission of an indication of the set of protocol data unit session switching patterns to the at least one user equipment and the radio access network.

An apparatus comprising processing circuitry and at least one memory including computer program code for one or more programs, the at least one memory and the computer program code configured to, with the processing circuitry, cause the apparatus at least to:

• establish at least two redundant protocol data unit sessions to at least one user equipment, wherein the at least two redundant protocol data unit sessions are established based on dual connectivity in a radio access network;
• collect network status information related to the at least two redundant protocol data unit sessions;
• configure a set of protocol data unit session switching patterns for the at least two redundant protocol data unit sessions based on the network status information;
• and
• cause transmission of an indication of the set of protocol data unit session switching patterns to the at least one user equipment and the radio access network.

A computer program product comprising at least one non-transitory computer-readable storage medium having computer executable program code instructions stored therein, the computer executable program code instructions comprising program code instructions configured, upon execution, to:

• establish at least two redundant protocol data unit sessions to at least one user equipment, wherein the at least two redundant protocol data unit sessions are established based on dual connectivity in a radio access network;
• collect network status information related to the at least two redundant protocol data unit sessions;
• configure a set of protocol data unit session switching patterns for the at least two redundant protocol data unit sessions based on the network status information;
• and
• cause transmission of an indication of the set of protocol data unit session switching patterns to the at least one user equipment and the radio access network.

A method comprising:

• receiving an indication of a set of protocol data unit session switching patterns from a core network;
• selecting a protocol data unit session switching pattern from the indicated set of protocol data unit session switching patterns;
• and
• causing transmission of an indication of the selected protocol data unit session switching pattern from the indicated set of protocol data unit session switching patterns to the core network.
