Seamless integrated network system for wireless communication systems
View Patent ↗To create a network that connects a plurality of wireless communication systems to create optimal systems for various environments, and that seamlessly integrates the resulting systems together in order to provide more efficient and advanced service in general. A network system that can seamlessly integrate wireless communication systems employs a heterogeneous network architecture with at least four building blocks, including a mobile host 40 , a wireless access network 41 , a common core network 42 , and an external network 43.
1. A network system that seamlessly integrates wireless communication systems, such network system being characterized in that:
an architecture of the network system including a mobile host, a wireless access network, a basic access network independent from the wireless access network, a common core network, and an external network; the external network having a correspondent node;
the external network and the common core network being connected together via at least one gateway router;
the common core network having two functional modules including a resource manager and a mobility manager;
the wireless access network internally comprising at least one set of base stations or access points, base station or access point interfaces, and network interfaces;
the base station or access point interfaces realizing an access mechanism that enable access between the common core network and the base stations or access points;
the network interface of the wireless access network realizing an access mechanism that enables access between the base stations or access points and the mobile host;
the basic access network internally comprising a network interface of base stations or access points, base stations or access points, and a basic access component, the basic access network allowing the mobile host to determine a location of the mobile host;
the network interface of base stations or access points of the basic access network realizing an access mechanism that enables access between the common core network and base stations or access points; and
the mobile host comprising at least a network interface, a network selector, a locator, a basic access component, and a local resource manager, the basic access component of the basic access network and the basic access component of the mobile host communicating with each other.
2. The network of claim 1 , wherein the basic access network has a larger service coverage than the wireless access network.
3. The network of claim 1 , wherein the basic access network provides discovery of available wireless system to the mobile host.
4. The network of claim 1 , wherein the basic access network is used for paging.
5. The network of claim 1 , wherein the basic access network provides low bandwidth messaging services including at least one of paging and broadcasting.
6. The network of claim 1 , wherein the basic access network is dedicted only to low bandwidth messaging services including at least one of paging and broadcasting, discovering available wireless system to the mobile host, and allowing the mobile host to determine the location of the mobile host.
7. The network of claim 1 , wherein the wireless access network and the basic access network are respectively dedicated to different specialized traffics for communicating with the mobile host.
