Problems solved by technology
However, for the sake of network integration, access devices such as base stations and base station controllers defined by standard systems such as 3GPP or 3GPP2 may not be able to use the IP network to access the core network. WiFi (802.11x), WiMax ( 802.16x) or Bluetooth (Bluetooth) and other technologies that use unlicensed wireless access frequency bands to achieve broadband wireless access, but wireless access points (WLAN APs) or other wired access methods in these unlicensed frequency bands cannot realize area information broadcast, the terminal cannot bring the area identifier of the roaming area to the core network
Therefore, in the existing technology, the core network cannot perform roaming and multi-scenario charging management on terminals accessed using unauthorized access technologies

[0050] attached image 3 It is a flow chart of the implementation steps of the first embodiment of the method for managing multiple scenarios of a terminal according to the present invention.
[0051] Step S210, configuring different virtual network labels for different access scenarios in the local access network. For example, when there are three scenarios of home, business building and hotel in the local access network, set the virtual network label VLAN1 corresponding to the home scenario, VLAN2 corresponding to the business building scenario, and VLAN3 corresponding to the hotel scenario for the three different scenarios. In this specific implementation manner, the corresponding information between the virtual network label and the access scene is set in a terminal access point, aggregation / switching device or router of the local access network.
[0052] Step S220, the address server configures the IP address-virtual network label binding relationship, and configures a d...

The invention discloses a method for carrying out roaming management to a terminal, which comprises the following steps: (a) an IP address is selected by a local access network according to the IP address-region mapping relationship and then distributed to the terminal; (b) the terminal transmits an access gateway domain name to the DNS server of the local access network; (c) a local DNS server provides an IP address of the access gateway for the terminal; (d) the terminal reports the own IP address to the access gateway by the signaling or data messages; (e) the access gateway determines theroaming region where the terminal is positioned; and (f) the access gateway reports the roaming region where the terminal is positioned to a core network. The invention also provides a method for carrying out multi-scene management to the terminal. The invention has the advantages that the terminal can be accessed to the access gateway by the broadband network or the internet by the unauthorized access technique, and then converged to the core network by the access gateway, and the invention can be applied to the access of the terminal by using the unauthorized wireless access technique and using the wired mode, thus having universality.
Description
【Technical field】 [0001] The invention relates to the technical field of communications, and in particular to methods for roaming management and multi-scenario access management for terminals. 【Background technique】 [0002] Roaming billing in existing mobile communication systems is mainly based on the concept of the user's roaming location and home location. When the user leaves the home location, the information of the user's visited location will be recorded in the home location register, which is used as the basis for the user's roaming. This is reflected in standards such as 3GPP and 3GPP2. [0003] For service scenario charging, 3GPP has SAI and SAC codes, that is, the concept of service area; 3GPP2 has the definition of user zone (user zone), and charges are distinguished according to the user's access area (scenario). [0004] The existing technical solutions are mainly aimed at the types of access networks defined by standards such as 3GPP and 3GPP2, and there are...
