FIELD: physics.
SUBSTANCE: invention relates to cellular mobile communication systems. Functional element for implementing policies and charging rules (PCRF) functions as a mobile router and performs steps of: receiving, from an additional node, a packet data network (PDN) connection request for a first UE, wherein the request comprises routing information of the first UE; receiving, from an application functional element (AF), a resource reservation request for a service based on a request from the second UE, wherein the request comprises an Internet Protocol (IP) address of the second UE; and correlating the routing information of the first UE with the IP address of the second UE.
EFFECT: technical result of the invention consists in achievement of services demarcation for the second UE connected to the first UE acting as a mobile router.
