Abstract
Access between a data terminal 1 and a data network 5 by way of a first wireless-enabled access point 3 is restored after a primary connection 4 between the first access point and the data network is lost by having the access point 3 scan for a further wireless-enabled access point 6 and establishing a wireless connection between the first access point 3 and the further access point 6 such that the data terminals 1 etc can connect to the data network by way of the access points 3, 6 and the wireless connection between them.
Claims9
A process for restoration of access between one or more data terminals and a data network by way of a first wireless-enabled access point in communication with the one or more data terminals through a wireless interface after a primary connection between the first wireless-enabled access point and the data network is lost, comprising:
- a) detecting loss of the primary connection to the data network;
- b) conducting a scan for a further wireless-enabled access point;
- c) establishing a wireless connection using the wireless interface between the first wireless-enabled access point and the further wireless-enabled access point;
- d) attempting connection between the first wireless-enabled access point and the data network by way of the further wireless-enabled access point;
- and
- e) if the first wireless-enabled access point successfully connects to the data network by the first wireless-enabled access point, establishing connection between the one or more data terminals and the data network by way of the first and further wireless-enabled access points;
- wherein the first wireless-enabled access point continues to monitor for availability of the primary connection to identify when connection by way of the primary connection becomes available, and restores its settings to effect such reconnection;
- and
- wherein such reconnection is deferred until any data session in progress has been completed.
A process for restoration of access between one or more data terminals and a data network by way of a first wireless-enabled access point in communication with the one or more data terminals through a wireless interface after a primary connection between the first wireless-enabled access point and the data network is lost, comprising:
- a) detecting loss of the primary connection to the data network;
- b) conducting a scan for a further wireless-enabled access point;
- c) establishing a wireless connection using the wireless interface between the first wireless-enabled access point and the further wireless-enabled access point;
- d) attempting connection between the first wireless-enabled access point and the data network by way of the further wireless-enabled access point;
- and
- e) if the first wireless-enabled access point successfully connects to the data network by the first wireless-enabled access point, establishing connection between the one or more data terminals and the data network by way of the first and further wireless-enabled access points;
- in which the first wireless-enabled access point transmits a message to the one or more user terminals connected to the first wireless-enabled access point to notify a user that connection is defaulting to a different access route.
A process for restoration of access between one or more data terminals and a data network by way of a first wireless-enabled access point in communication with the one or more data terminals through a wireless interface after a primary connection between the first wireless-enabled access point and the data network is lost, comprising:
- a) detecting loss of the primary connection to the data network;
- b) conducting a scan for a further wireless-enabled access point;
- c) establishing a wireless connection using the wireless interface between the first wireless-enabled access point and the further wireless-enabled access point;
- d) attempting connection between the first wireless-enabled access point and the data network by way of the further wireless-enabled access point;
- and
- e) if the first wireless-enabled access point successfully connects to the data network by the first wireless-enabled access point, establishing connection between the one or more data terminals and the data network by way of the first and further wireless-enabled access points;
- in which the first wireless-enabled access point suspends advertising its presence whilst the primary connection is unavailable;
- and
- in which once the first wireless-enabled access point has successfully restored connection to the data network by way of a further wireless-enabled access point, the first wireless-enabled access point resumes advertising its presence such that yet further wireless-enabled access points may, in turn, restore connection to the data network by way of the first and further wireless-enabled access points after deferring such reconnection until any data session in progress has been completed.
A wireless-enabled access point for connecting one or more user terminals to a data network, the wireless-enabled access point comprising:
- a wireless interface to communicate with the user terminals,
- a second interface arranged to provide a primary connection to the data network,
- a connection monitor to detect loss of the primary connection,
- a scanner to detect the presence of one or more further wireless-enabled access points, and arranged to establish a wireless connection to the data network by way of the wireless interface and one of the further wireless-enabled access points, and
- a switching processor for connecting user terminals to the data network by way of the first and further wireless-enabled access points;
- wherein the connection monitor is arranged to continue to monitor for availability of the primary connection, and the switching processor is arranged to restore connection between the user terminals and the primary connection when connection by way of the primary connection becomes available;
- and
- wherein the connection monitor is arranged to detect running of a data session by way of the further wireless enabled access point and defer reconnection over the primary connection until the data session in progress has been completed.
A wireless-enabled access point for connecting one or more user terminals to a data network, the wireless-enabled access point comprising:
- a wireless interface to communicate with the user terminals,
- a second interface arranged to provide a primary connection to the data network,
- a connection monitor to detect loss of the primary connection,
- a scanner to detect the presence of one or more further wireless-enabled access points, and arranged to establish a wireless connection to the data network by way of the wireless interface and one of the further wireless-enabled access points, and
- a switching processor for connecting user terminals to the data network by way of the first and further wireless-enabled access points;
- wherein the wireless-enabled access point is arranged to transmit a message to one or more user terminals connected to the wireless-enabled access point indicative of the redirection of the connection.
A wireless-enabled access point for connecting one or more user terminals to a data network, the wireless-enabled access point comprising:
- a wireless interface to communicate with the user terminals,
- a second interface arranged to provide a primary connection to the data network,
- a connection monitor to detect loss of the primary connection,
- a scanner to detect the presence of one or more further wireless-enabled access points, and arranged to establish a wireless connection to the data network by way of the wireless interface and one of the further wireless-enabled access points, and
- a switching processor for connecting user terminals to the data network by way of the first and further wireless-enabled access points;
- wherein the wireless-enabled access point is arranged to suspend advertising its presence whilst the primary connection is unavailable;
- and
- wherein the wireless-enabled access point is arranged to resume advertising its presence when the wireless-enabled access point has successfully restored connection to the data network by way of a further wireless-enabled access point, such that yet further wireless-enabled access points may, in turn, restore connection to the data network by way of the first and further wireless-enabled access points after deferring such reconnection until any data session in progress has been completed.
