An automobile's maintenance port is wirelessly connected (for example, via an IEEE 802.11-based connection) to a plurality of gateways/routers that forward automobile diagnostic data (such as a series of diagnostic codes) to a network analyzer server. The network analyzer server offers subscribers a service providing analysis of the received diagnostic data, wherein such analyzed information is transmitted to one or more predetermined locations (such as to a personal computer of the subscriber or a mechanic's diagnostic device at a service station). Thus, homeowners and garages receive the same data and the system eliminates the need for garages to purchase expensive engine analyzers.

Methods and apparatus for maintaining connectivity with an Internet protocol (IP) phone operating behind a firewall are disclosed. An example method disclosed herein comprises registering the IP phone in response to receiving a first registration request from the IP phone, the first registration request including first registration information, the first registration information including a first public IP address associated with the firewall, storing the first registration information, reregistering the IP phone in response to receiving a second registration request from the IP phone, the second registration request including second registration information, the second registration information including a second public IP address associated with the firewall, the second public IP address different from the first public IP address, and reverting to the stored first registration information to process calls associated with the IP phone.

A residential gateway connects an Internet connection to an in-home network that has at least one residential device connected to the residential gateway. The residential gateway has software that receives control parameters from a control server via the Internet connection. The control server determines the control parameters from operational information of the residential device and relevant control information accessed from an information server on the Internet. The software causes the residential gateway to communicate with the residential device to provide control of the residential device based on the received control parameters. In a particular implementation, the residential device is a home irrigation system connected to the residential gateway via a wireless interface and the information server is a weather station server storing climatic information from a plurality of weather stations.

A network node sets up a virtual connection in a network based on a virtual connection request initiated from an access port different from a first location previously associated with an account of a user. The network node includes a receiver for receiving a signaling message from the access port requesting the virtual connection. The signaling message has at least one field modified to include an address of the access port. The network node further includes a profile database and a registration server. The profile database stores a service policy associated with the user account. The registration server stores an address of the first location associated with the user account as a default registration, determines whether the user is authorized to establish the virtual connection based on the service policy, and replaces the first location address with the access port address when the user is authorized.

A connection between an external host and a host internal to a network (e.g., VPN or LAN) and located behind a firewall and/or NAT-enabled device is established and maintained. A dynamic DNS server is updated with the remote location (RL) information associated with the internal host. This information includes the dialed number (i.e. the number assigned to the internal host), the physical address of the internal host, the private IP address corresponding to the internal host, the public IP address corresponding to the firewall, and the port on which voice data is to be communicated. Each time the internal host's location changes, a new and updated record is sent to the dynamic DNS server. The call placed by an external host reaches its final destination based on the record information in the DNS server table. Once the connection between the external host and the internal host is established, voice traffic is “cut-through” the firewall on this channel associate with the port designated by the RL record.

A system allows switch signaling to be processed in a controller adjunct to a switch, and for the controller to effect the connection by signaling to the switch. This is accomplished by an end unit communicating service information to a controller and the controller instructing the switch to carry out the service transaction. The service information from the end unit is routed through the switch being controlled by the controller.
