Patent Images
1. A method for determining a presence of a relay node in a wireless communications system, wherein the relay node is configured to wirelessly communicate with an access node in the system, the method comprising:
- receiving, by a user agent in the system, information indicating the presence of at least one of the access node and the relay node from a network node in the system, wherein the user agent is not a relay node; and
determining, by the user agent, whether the network node is the access node or the relay node, based on the information,wherein the information comprises a list of node identifiers for at least one relay node in a cell covered by the access node, and wherein the list is included in a connection-setup message sent to the user agent by the access node upon the user agent sending a random access message to the access node.

Abstract
A method for determining a presence of a relay node in a wireless communications system. The method includes receiving, from a network node in the system, information indicating the presence of at least one of an access node and the relay node. The method further includes determining whether the network node is the one of the access node and the relay node based on the information.

4. A user agent for operating in a wireless communications network including an access node configured to wirelessly communicate with a relay node, comprising:
-
a processor configured to receive information indicating a presence of at least one of the access node and the relay node, and further configured to analyze the information to determine whether a network node is the access node or the relay node, wherein the user agent is not a relay node, wherein the information comprises a list of relay node identifiers for at least one relay node in a cell covered by the access node, and wherein the list is included in a connection-setup message sent to the user agent by the access node upon the user agent sending a random access message to the access node. - View Dependent Claims (5, 6)

7. A wireless communications system, comprising:
-
a network node configured to transmit a connection setup message including information indicating that the network node is a relay node, the information usable to determine whether the network node is the relay node, wherein the connection setup message further includes a list of node identifiers for at least one relay node in a cell covered by an access node, wherein the connection-setup message is sent to a user agent by the network node upon the network node receiving a random access message from the user agent. - View Dependent Claims (8, 9, 10, 11)

12. A method for determining that a network node in a wireless communications system is a relay node, the method comprising:
-
receiving from the network node a connection setup message including a subset of information indicating that the network node is a relay node; and determining that the network node is the relay node by using the subset of information, wherein the connection setup message further includes a list of node identifiers for at least one relay node in a cell covered by an access node, wherein the connection-setup message is sent to a user agent by the network node upon the user agent sending a random access message to the network node. - View Dependent Claims (13)
