Techniques of controlling discovery of a proxy node (103, 103-1, 103-2, 103-3), e.g., a P-CSCF, by a user equipment (201) of a communication network are provided. The user equipment (201) seeks to establish a data connection with a packet-based multimedia core network (250), e.g., an IMS, via the proxy node (103, 103-1, 103-2, 103-3). Based on an availability condition of the proxy node (103, 103-1, 103-2, 103-3), an identity of the proxy node (103, 103-1, 103-2, 103-3) is selectively signaled to the user equipment (201). |
