Methods of detecting protocol support in wireless communication systems
First Claim
1. A method by which a source node of a wireless network detects whether a destination node supports a given protocol version, so as to establish communications, via the source and destination nodes between a user of the wireless network and an external network, comprising:
- sending a request message from the source node to the destination mode based on a first protocol version that is not supported by the destination node;
receiving, at the source node, an indication message in reply to the request; and
detecting that the destination node does not support the first protocol version based on the indication message.

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.

-
sending a request message from the source node to the destination mode based on a first protocol version that is not supported by the destination node;
receiving, at the source node, an indication message in reply to the request; and
detecting that the destination node does not support the first protocol version based on the indication message. - View Dependent Claims (2, 3, 4, 5, 6, 7, 8, 9, 10)

11. A method by which a destination node indicates that it does not support a given protocol version to a source node of a wireless network, comprising:
-
receiving a request message from the source node that is based on a first protocol version not supported by the destination node, the request message for establishing communications, via the source and destination nodes between a user of the wireless network and an external network; and
sending an indication message in reply that informs the source node that the first protocol version is not supported by the destination node, so as to enable the source node to re-send the request message using a second protocol version supported by the destination node. - View Dependent Claims (12, 13, 14, 15, 16)

17. A method of facilitating an activation routine to enable a user of a wireless network to make its presence known to a given external network, comprising:
-
sending an activation message from the user to a source node of the wireless network to establish communications between the source node and a destination node that enables access to the external network;
sending a request message from the source node to the destination mode based on a first protocol version that is not supported by the destination node;
receiving an indication message at the source node in reply to the request message that informs the source node that the first protocol version is not supported by the destination node; and
re-sending the request message from the source node to the destination mode at a second protocol version supported by the destination node, responding to the source node with an accept message, and confirming the activation message at the source node so that the user'"'"'s presence is known to the external network. - View Dependent Claims (18, 19, 20)
