AI Technical Summary

Problems solved by technology

Constraint-based routing within an MPLS network can guarantee trunk bandwidth or other class-of-service characteristics, but it cannot guarantee corresponding resources for individual communication sessions
Furthermore, MPLS does not provide a means for selecting a network based on criteria defined within the first network

Embodiment Construction

[0036] In the figure, the solid line represents the session control, the dashed line represents the connectivity path, the BE represents the border element, and the SS session server.

[0037] figure 2 The selection of networks 1-5 is schematically illustrated, each network having a network selection system according to the invention for establishing a desired communication channel. The exchange of network information, such as network parameter values, between respective network selectors is performed via the network selector communication channel 10 . The protocol for exchanging network information is called the Network Selection Protocol (ONSP). A network selection communication channel 10 represents a commercial relationship between network operators. The network selector has an advertising policy for each communication channel 10, which is the use of the commercial relationship between the two operators of the corresponding network.

[0038] The network selection system...

Abstract

The present invention relates to data communication over multiple communication networks such as IP, ATM, STM, PLMN etc. networks, and more particularly to network selection of connections. A system is provided within the first network for receiving and storing information from the second network on the services offered, the quality of service and costs, and for transmitting corresponding information from the first network to the second network, so that the The selection of the second network for data transmission is performed based on criteria such as desired quality of service and cost defined within the first network.

Description

technical field [0001] The present invention relates to data communication over multiple communication networks such as IP, ATM, STM, PLMN etc. networks, and more particularly to network selection of connections. Background technique [0002] Until recently, network operators built and configured their networks to carry voice traffic only. Each residential user requires at most one telephone line, which is used for voice. In the late twentieth century, fixed and mobile telephony and data communications have proliferated within a separate networked world. These networks share the same type of transport equipment, and a growing portion of telephony traffic consists of dial-up Internet access. Broadband access has primarily emerged as high-speed data circuits for large companies. [0003] Each of these known networks has its own management system, its own resources for switching, transmission and access, and its own terminal types. Each operator is responsible for all affai...
