A method is disclosed for authorizing a prepaid network service in a data network. A network end station issues a request for a prepaid network service. At a network node, such as a router serving as a gateway for selecting services, a determination is made about whether a user associated with the end station is authorized to access the prepaid network service. Network traffic from the end station is forwarded to a service provider only when the user is authorized to use the prepaid network service. Specific embodiments provide message flows among a mobile station, gateway support node, router, and authentication server that support providing prepaid services in a packet-switched network for mobile communication. In certain embodiments, a connection is held open for an end station while a prepaid quota value is refreshed at a portal, thereby reducing overhead and precluding the need to repeat user logon steps. Further, unused quota amounts can be returned to the authentication server for use in association with multiple concurrent connections of the same device.

To send a connection control message associated with a first set of attributes, only a difference of the first set of attributes from a second set of attributes associated with an already active virtual circuit (to a common destination) may be sent (contained in the connection control message). The devices receiving the message may create the necessary configuration for the new virtual circuit by modifying a copy of the configuration of the active virtual circuit. Processing requirements may be minimized as the devices may not need to parse and decode long list of information element. The feature may be particularly important in setting up a virtual circuit for voice calls, as a long list of attributes may be associated with each virtual circuit, but the difference of attributes being only minimal.

Described is a method and system for context aware profiling for wireless networks. The system may include a mobile unit and an access point. The mobile unit may includes a plurality of predefined contexts; each context including corresponding network settings. The mobile unit selects one of the predefined contexts and formatting and transmitting a request signal to enable the one of the predefined contexts. The access point includes the plurality of predefined contexts and receives the request signal from the mobile unit. The access point determines if the mobile unit has permission to enable the one of the predefined contexts and sends one of a permission signal and a denial signal to the mobile unit. When a permission signal is sent, the access point and the mobile unit apply the network settings corresponding to the one of the predefined contexts.

Several keep-alive messages of point to point (PPP) sessions received from a remote system are aggregated into a single packet in an aggregation device (e.g., network access server). The aggregated packet is sent to a peer aggregation device (e.g., home gateway) at the other end of the PPP session. The peer aggregation device may send the status of the sessions in a single packet. As a result, the data traffic on a communication backbone due to keep-alive status checks may be reduced. Without waiting for the peer aggregation device to provide the status information, a proxy reply may be generated from the aggregation device.
摘要:
Described is a system and method for controlling bandwidth at a wireless endpoint. The method comprises receiving a bandwidth request from a device and placing the device in a bundle which includes a plurality of radios to communicate with the device. A packet addressed to the device is received and transmitted to the device via the plurality of radios.

Described is a system comprising a computing device detachably coupled to an input arrangement. Upon authenticating a user, a corresponding user profile is retrieved from a memory module and uploaded into at least one of the device and the arrangement. The profile stores user's preferences for inputting data via the input arrangement. The memory module is situated in at least one of the device and the arrangement.

Described is a system and method for management of a wireless environment. The system may includes a network management arrangement (“NMA”), a wireless mobile unit (“MU”) and an access point (“AP). The AP receives a request for an association from the MU and transmits the request to the NMA. The NMA determines if the request is to be granted as a function of at least one of a plurality of predetermined factors which may include a data traffic load of the AP. If the request is not granted, the NMA determines a further AP to grant the request instead of the AP and instructs the AP to transmit a response to the MU including identification data of the further AP.
摘要:
A network device (e.g., network access server or home gateway) providing different QOS (quality of services) to different layer-3 datagrams when transporting on tunnels. A tunnel may be implemented to provide different QOS to different packets depending on the packet header. The network device examines the header of each datagram to determine the specific QOS to be provided. At least the data portion in the datagram is encapsulated for transportation on the tunnel. The encapsulated data portion in turn is encapsulated in the form of one or more packets, with the packet format to reflect the QOS determined for the datagram. When the tunnel is implemented on UDP/IP and the datagram is an IP (Internet protocol) datagram, the TOS/Precedence bits of the IP datagram may be copied into the precedence/TOS bits of the UDP/IP packet(s).

Described is a system and method for scheduling delivery of traffic in a wireless network. The method comprises receiving packets addressed to a plurality of wireless computing units. A classification of each packet is determined. A transmission schedule is generated for the corresponding packet as a function of at least one of the classification and a priority request from at least one of the plurality of units. An indication message is generated as a function of the transmission schedule. A signal including the indication message is wirelessly transmitted.
摘要:
Described is a method which includes receiving an association request from a first wireless device to establish an emergency connection via a wireless communications network. A wireless bandwidth availability required to grant the request is analyzed. When the bandwidth is unavailable, a wireless connection between a second wireless device and the wireless network is terminated and the request of the first device is granted.
