Claim 10:
11. A network node of a communication network, comprising:
a processor; and
a memory containing instructions executable by the processor, wherein execution of the instructions configures the network node to:
obtain an evolved packet system (EPS) bearer identity (ID), associated with a terminal device, from a mobility management entity (MME) or an evolved packet data network gateway (ePDG) of the communication network; and
select, for the terminal device, a particular protocol data unit (PDU) session ID from a group of PDU session IDs that are not allocated to the terminal device by the communication network, wherein the particular PDU session ID is selected based on the EPS Bearer ID and the following:
a first mapping relationship to the EPS Bearer ID when the EPS Bearer ID is obtained from the MME; and
a second mapping relationship to the EPS Bearer ID when the EPS Bearer ID is obtained from the ePDG.
