Abstract

A method and an arrangement for re-establishing connectivity or reachability (116) between a server (100) and a client (108), for example following interruption or deterioration in the connectivity or reachability. A client and/or application handles connectivity or reachability with or towards at least one server comprising: establishing connectivity or reachability between said client and/or application (604, Figure 6) and said at least one server; transmitting a registration message (Figure 4) to said server comprising a client communication port identifier (624, Figure 6) and optionally a terminal address (620, Figure 6) of the client and/or application; and receiving a re-establishment message (Figure 5) using a different type of communication than the connectivity or reachability, the re-establishment message making or enabling said client and/or application re-establish said connectivity or reachability with or towards said at least one server. The communication port identifier may identify a WAP-push port and the address may be a MSISDN. The connectivity or reachability may comprise a TCP or TLS based connection and the re-establishment message may be sent using a different network such as using an SMS message. The connectivity or reachability may be established via or through a pinhole in a firewall (106). A deterioration in the connectivity or reachability may be monitored and detected by termination or expiry of an open state of the pinhole, which occurs for example when keep alive messages are not received or the firewall behaves in an unexpected way. A SIP or IMS platform may also be used.
