A system and method are described whereby a mobile device controls access to mobile applications based on access conditions associated with a current access network. To prevent mobile applications from running when the access conditions are not suitable, the mobile device includes a policy database used to store a list of access conditions that are inappropriate for launching the installed applications. The access conditions are based on the type of the current access network used by the mobile device for launching or maintaining the requested application session. The access conditions indicate whether the mobile device is currently accessing its home network or roaming on another provider's network. Similarly, the access conditions indicate the type of network access interface used by the current network to provide the data connection necessary to run the requested application. The policy database correlates predetermined actions with the access conditions associated with a given application session.

A fast authentication and access control method of authenticating a network access device to a communications network having an access point communicating with a remote authentication (home AAA) server for the network access device. The method includes the step of receiving an access request having an authentication credential from the network access device at the access point. The authentication credential includes a security certificate having a public key for the network access device and an expiration time. The security certificate is signed with a private key for the remote authentication server. The access point locally validates the authentication credential by accessing the public key of the remote authentication server from a local database, and checking the signature and expiration time of the security certificate. If the authentication credential is validated at the access point, the access point grants the network access device conditional access to the network by sending an access granted message to the network access device. The access granted message includes a session key encrypted with a public key for the network access device. The session key is stored in a database associated with the access point. The access point contacts the remote authentication server to check a revocation status of the security certificate for the network access device. If the access point receives a message from the remote authentication server that the authentication credential for the network access device has been revoked, it suspends network access for the network access device.

Under Simple Multicast Extension for Mobile IP, when a mobile node arrives at a foreign wireless domain, it listens for an agent advertisement sent by a foreign agent. The foreign agent attaches a network access identifier (NAI) extension to the agent advertisement. The mobile node uses the NAI extension to decide which action to take. If the mobile node determines that it is receiving an agent advertisement message from the same foreign agent it previously was in communication with, no action is required. If the mobile node discovers that it has entered a new foreign domain, it sends a registration request to the foreign agent. If the mobile node identifies that it is still in the same domain but has moved from a previous foreign agent to a new one, it sends a multicast subscription request to the new foreign agent.

If a home agent supports the Simple Multicast Extension for Mobile IP, it allocates a source specific multicast address and inserts the address in a source specific multicast address extension after the registration reply. In addition, tunneling is used to route datagrams from correspondent nodes to the mobile node while the mobile node is in a foreign domain. The destination address of the tunnel is set to the source specific multicast previously allocated. Finally, update messages are used to inform correspondent nodes of a mobile nodes' new location.

A database is populated with geographic locations for network devices by providing a node on a network and making a connection into a network service provider (NSP) point of presence (POP) to obtain a connection to the network via the NSP. A message is then transmitted to the node over the network connection obtained from the NSP. The message is received at the node and a source network identifier is extracted from the message. The source network identifier is then associated with a known geographic location for the POP in a database. The foregoing steps are then repeated for multiple different POPs. Also, a database is populated with geographic locations for network devices by providing a node on a network and making a connection into a network service provider (NSP) point of presence (POP) to obtain a connection to the network via the NSP. A message is then transmitted to the node over the network connection obtained from the NSP. The message is received at the node and a source network identifier is extracted from the message. The route over the network between the node and the POP is then probed to obtain network identifiers for routers along the route. The foregoing steps are then repeated for multiple different POPs.

A method is provided for conducting surveillance on a network. Data is captured on a network for a plurality of aggregated channels. The data is from individuals with network access identifiers that permit the individuals to gain access to the network, or applications on the network. The data is used to construct a plurality of session data streams. The session data streams provide a reconstruction of business activity participated in by the application or the individual with the network. A window of data is read in at least one of the plurality of session data streams to determine deviations. The window of data is tested against at least one filter. The at least one filter detects behavioral changes in the applications or the individuals that have the network access identifiers to access to the network. Defined intervention are taken in response to the deviations.

A loop carrier system includes a home local area network having plural telephone modules and a hub coupled to in-home telephone wiring. The telephone modules and the hub communicate voice signals over the in-home wiring in a dedicated frequency band above baseband POTS. The hub converts between voice signals and voice packets and is connected to a network access device for transferring the voice packets from the home local area network to a telecommunications network which routes the voice packets to a gateway. The gateway converts between the voice packets and a circuit format compatible with a local digital voice switch. The gateway includes an ATM switch and a call processing adjunct coupled to the ATM switch. The call processing adjunct controls the conversion between voice packets and the circuit format at the ATM switch. The call processing adjunct communicates with the home local area network using a first signaling protocol such as Media Gateway Control Protocol, Session Initiation Protocol or H.323, and with the local digital switch using a second signaling protocol such as GR-303 for controlling call processing in the communication system.

A method of modifying network identifiers at data servers is disclosed. A virtual private network (VPN) gateway server generates a Hypertext Transfer Protocol (HTTP) request. The HTTP request not only requests data from a data server that is within a VPN, but also instructs the data server to modify (“mangle”) URLs that are contained within the requested data so that the URLs refer to the VPN gateway server. The VPN gateway server sends the HTTP request toward the data server. As a result, the data server modifies the URLs so that the VPN gateway server does not need to. When such a modified URLs is selected in a web browser, the web browser generates an HTTP request that is directed to the VPN gateway server's URL, which, unlike the unmodified URLs, can be resolved by domain name servers that are outside of the VPN.

A new extensions structure for mobile IP control message extensions is employed to conserve the type field. Certain types of extensions, such as network access identifiers, are initially aggregated and subtypes are employed to identify the precise content of the extension (e.g., mobile node network access identifier, home agent network access identifier, foreign agent network access identifier, etc.). Long and short formats for the new extension structure are defined, with the long format applicable to nonskippable extensions carrying more than 256 bytes and the short format backwards compatible with currently defined skippable extensions with less than 256 bytes of data. This will greatly reduce usage of the type field.

A mechanism for selecting a serving network access entity for a mobile node in a communication system including network access entities broadcasting periodic advertisement messages. The method utilizes a waiting period measured from a first reference moment. When no advertisement message is received within the waiting period from the network access entity being currently the serving network access entity for the mobile node, the node issues a router solicitation message and initiates a measurement of a solicitation period from a second reference moment. The mobile node further monitors whether a response to the router solicitation message is received from the network access entity within the solicitation period, and based on the monitoring step decides whether it remains connected to the said network access entity.

The present invention supports a protocol for a mobile node to specifically designate a home agent and Authentication, Authorization, and Accounting (AAA) server to use in a communication session. By specifying the AAA server, a specific security association can be selected to support secure information packet transmission between a specified home agent and a mobile node. The specific home agent and AAA server are designated using a network access identifier extension on a binding update message, and the security association data is transmitted back to the mobile node using an extension to the binding acknowledgment message. The mobile node and the home agent then use the security association generated by the AAA server to support information packet communication between the mobile node and the home agent.

An apparatus and method of controlling unsolicited traffic are disclosed herein. The apparatus and method can be applied to wireless communication networks such as CDMA2000, UMTS, GPRS and the like so that traffic which is not solicited by wireless communication devices operating on those networks is not sent over the air needlessly. The present application provides techniques to block unsolicited traffic based on the identity of a user (for example based on International Mobile Station Identity (IMSI), Network Access Identifier (NAI), Mobile Station Internet Services Digital Network Number (MSISDN), Session Initiation Protocol (SIP) Universal Resource Locator (url)) as opposed to techniques that are based on a session or IP address, such as a traditional firewall. In accordance to this application, user identity based techniques are applied to block unsolicited traffic whenever a user has established a data session. Further in accordance with this application, user identity based techniques are persisted across changes in IP address and/or session.

Embodiments of the present disclosure provide for configuring and managing mesh nodes during occasional failure of mesh nodes or addition of new mesh nodes. The disclosed system first determines whether a mesh node is a mesh portal or a mesh point. If it is a mesh portal, the mesh node will advertise its capacity as a mesh portal to other mesh nodes in the network. If it is a mesh point, the mesh node attempts to automatically recover connection to the wireless mesh network if it identifies a unique wireless network based on its associated network identifier. If more than one network identifiers are discovered, the mesh node delays establishing connection to the wireless mesh network until a selection is received.
