Description

Routing method, system and mobile communication router providing multiple services

The present invention relates to a routing method, system, and router for providing services, and more particularly to a routing method, system, and mobile communication router for providing multiple services.

Currently, existing mobile communication routers (for example, 3rd-generation/Long Term Evolution (3G/LTE) routers) can provide access devices on a local area network (Local Area Netwofk, LAN). Through the Wireless Wide Area Network (WWAN), it is like a 3G or LTE mobile communication network connected to the Internet.

In addition, in addition to providing Internet services, mobile communication operators are also offering new services such as Multimedia Messaging Service (MMS), Voice over Internet Protocol (VoIP) and mobile video services. Currently, users can use these new services through handheld devices such as mobile phones.

The first figure shows the network architecture of the current Internet access device connected to the mobile communication router. As shown in FIG. 1, the Internet access devices 101 and 102 on the local area network 110 are connected to the base station 130 through the mobile communication router 120, and then use the Internet Access Point Name (Internet Access Point Name, Internet APN) and the mobile communication. An Internet Gateway 150 on the Core Network 140 is connected to the Internet 160.

FIG. 2 is a block diagram showing the module of the current mobile communication router 120. As shown in FIG. 2 and referring to FIG. 1, the mobile communication router 120 includes a mobile communication module 121, a router processor 122, and a regional network module/wireless area network module 123. The mobile communication module 121 can connect the mobile communication router 120 to a mobile communication network (for example, a 3G or LTE network). The router processor 122 is responsible for the connection management and network packet forwarding of the mobile communication network (including routing and network address translation (NAT). Regional network module/wireless area network module 123 allows the Internet devices 101 and 102 to be connected to the mobile communication router 120.

However, today's mobile operators have provided new services through different access point names. The mobile communication router can identify the service required by the Internet access device on the local area network through the Internet address, protocol ID and port number in the network packet. Then use the corresponding access point name to direct the network packet to the correct gateway. However, in this multi-service network, the network connected to each gateway usually has a separate Domain Name System Server (DNS Server). If the architecture of today's mobile communication routers is used, Internet devices on the local area network will not be able to distinguish when to use which domain name system server.

In view of this, a routing method, a system, and a mobile communication router that further provide multiple services are yet to be developed.
