Techniques for controlling a network connection in accordance with connection information associated with a destination location on a network are disclosed. Controlling of the network connection in accordance with connection information associated with the destination location can be achieved in a variety of ways.

In either case, the connection information includes information with which the selection of the network transport and/or connection parameters can be made. The controlling of the network connection impacts quality of service provided to a requestor that is requesting use of the connection.

The present invention provides a method and an apparatus for controlling service quality of data communications in a wireless network in which quality of service control for voice over internet protocol packets is provided on a downlink shared channel. A method is provided for a wireless communications between at least a first and a second service user. The method comprises prioritizing transmission of voice over internet protocol packets for the first and second service users over a shared downlink channel based on a first end-to-end delay that the first service user experiences relative to a second end-to-end delay that the second service user experiences. For example, such a priority adaptation may provide quality of service control for voice over internet protocol over a high-speed downlink packet access channel based on an end-to-end delay that a mobile-to-mobile user may be currently experiencing relative to a mobile-to-land user. In this way, a scheduler at a base station of a communications system may maximize use of voice over internet protocol capacity while maintaining an acceptable level of end-to-end delay for different users of mobile stations.

There is provided methods, devices and computer program products for distributing a plurality of virtual IEEE 802.11 wireless networks through a heterogeneous infrastructure. A terminal sends a service provider request to an access point. The service provider request is forwarded to a master server which searches for available service providers. Acknowledgement information relating to available service providers capable of operatively connecting the terminal to the data communications network via the access point is sent by the master server to the access point. The access point forwards this information to the terminal. The access point may thus distribute a plurality of virtual IEEE 802.11 wireless networks, their number only constrained by the number of distinct identifiable service providers and the memory of the master server. A data connection may be established in the absence of a direct service agreement between the service provider of the terminal and the operator of the access point.

Described is a method where a wireless mobile unit (“MU”) transmits an association request and an authentication request to an access point (“AP”). The association request includes an identifier of the MU and the authentication request includes authentication data of the MU. An authentication procedure of the MU is performed as a function of the identifier and the authentication data. The AP adds the identifier and the authentication data to an authenticated list. Access to the list is provided to at least one further AP. When the at least one further AP receives a further association request including the identifier from the MU, the further AP performs a further authentication procedure as a function of the identifier and the list.

A telecommunications system provides mobile internet protocol related communications services to mobile nodes via a plurality of access networks. A mobility manager directs a change of affiliation of a first mobile node between the access networks, or a change of communications session level of the mobile node, in accordance with the congestion state of the access networks, the link quality currently experienced by the mobile node, applications server messages and the level of service quality to which the first mobile node has subscribed. A quality of service for communications sessions of a mobile nodes can be maintained even on unregulated access networks, such as Wireless Local Area Networks (WLAN) independently of a Mobile IP v4/v6 stack. Moreover congested access networks can be decongested by controlling the communications bandwidth used by the mobile nodes.

A system and method for transmitting packet data to a hybrid mobile terminal upon inter-system handoff is provided. The terminal communicates with High Rate Pack Data (HRPD) and voice mobile networks. A Packet Control Function (PCF) system converts received data for transmission to the terminal into Generic Routing Encapsulation (GRE) packet data, stores the GRE packet data combined with a GRE packet key in an active queue, transmits it to an access network, and stores packet data stored in the active queue in a dormant queue when receiving a link release message from the access network. The access network converts GRE packet data received from the PCF system into an Radio Link Protocol Data (RLP) packet, stores it in combination with a GRE packet sequence number, and transmits it to the terminal. When detecting air link loss with the terminal, the access network creates and transmits a link release message including a GRE packet sequence number that has not been transmitted to the terminal.
