ABSTRACT:
In a method of detecting whether a given node supports a given protocol version, a source node sends a request message to the destination mode based on a first protocol version. The source node receives an indication message in reply to the request, and may detect that the destination node does not support the first protocol version based on the indication message. Accordingly communications may be established between a user of the wireless network and an external network via the source and destination nodes.
