A system and method set specific communication parameters, with the method including identifying a communication relay for allocating addresses. A STUN communication relay can be directed to a specific type of communication such as IMS-specific communication. The communication server ID information is then transmitted to a network, with the communication server being identified as IMS specific. Media flow to and from the communication server for non-specific sessions is therefore blocked. Addresses are allocated by the communication server to user equipment only for specific sessions. Optionally, outbound/uplink traffic may routed from the relay and inbound/downlink traffic may be routed to IMS-specific IP addresses by a policy and charging enforcement function. Also, a time-out unit may re-configure the relay to enable non-IMS sessions if there has been no IMS traffic for a period of time. |
