Definitions
- the invention relates to a method and a terminal for selecting a communication network and for registering a terminal in a communication network in the coverage area it is located.
- 3GPP services will be offered in the future via various IP based access networks.
- Examples include so-called interworking-capable WLANs (I-WLAN, Interworking Wireless Local Area Network) which are connected to mobile networks and standardized in the 3GPP.
- Other examples are WIMAX and xDSL access networks, and WIMAX in particular is thinking of a similar architecture for connecting to mobile networks such as WLAN.
- WIMAX In connection with wireless access networks such as WLAN, one of the most important problems is network search. It is both the search for an optimal
- Access network in a hotspot, for example, several wireless networks can be operated) and in roaming the search for an optimal mobile network or other intermediate networks that can be reached via the access network, a problem to be solved.
- the terminal has selected an I-WLAN, this can be connected to several mobile networks. These communication networks must be announced to the terminal by the I-WLAN so that it can select a preferred mobile network.
- the lists of preferred networks are stored either in the terminal or on the USIM card.
- the terminal searches for all available WLANs, then logs into each WLAN in turn and tries to authenticate itself to its home mobile radio network (automatic selection procedure).
- the selected WLAN is not an I-WLAN, this attempt fails and the terminal must log in to the next available WLAN.
- the WLAN network is an I-WLAN according to the 3GPP standard, but not directly connected to the subscriber's home mobile radio network (roaming case)
- the I-WLAN sends to the terminal a list of the mobile radio networks to which it is directly connected.
- the terminal then continues its search for I-WLAN networks. Based on the information obtained, the terminal selects an I-WLAN and mobile network to which it connects, according to preconfigured lists of preferred I-WLAN and mobile networks at the end of the search process.
- the standard also describes a method in which an I-WLAN can already inform the terminal during its search for WLAN networks of its ability to interoperate (interworking) and the connected mobile radio networks. Since this information (so-called SSID, Service Set Id) is transmitted by the WLAN radio stations in the broadcast method (multiversand method) prior to logging into the WLAN network, this would simplify the search procedure.
- SSID Service Set Id
- the WLAN technology 802.11 3GPP does not necessarily prescribe the structure of the SSID in the WLAN broadcast, not standardized by 3GPP but by IEEE.
- the SSID field has a limited length (32 bytes), so that it may not be possible to store all the information about all the connected mobile radio networks there.
- the SSID is also configured by the wireless network operator and can therefore be flawed or misleading.
- the 3GPP standard offers only the optional option within the WLAN SSID information about the interworking Ability to send a WLAN.
- the connected mobile networks can determine the terminal only after it has checked in with all available I-WLANs and received from there the corresponding data.
- the optimal access network and the preferred mobile radio network is determined by statically preconfigured lists on the (U) SIM card or the terminal itself. These lists are stored by the home network operator once on the (U) SIM or can be manually supplemented and prioritized by the user. This procedure is inflexible and expensive for the network operator, difficult and uncomfortable for the subscriber.
- the object of the invention is to propose for a terminal a simple and efficient way to select a communication network.
- a core of the invention is to be seen in that the selection of a communication network, for example an access network, a WLAN network, a cellular mobile radio network, an IP network or another communication network through the use of a further network unit, for example a register unit, a Database, a storage unit, etc., for example, in the HPLMN network (home network) flexibilized and accelerated.
- this further network unit can also be operated, for example, on the Internet or another communications network and receive data via all possible communication networks.
- this requires further agreements between the network operators and an entity that then operates this further network entity.
- This further network unit could be called "IP Access Register.”
- the terminal is looking, for example, for an I-WLAN-capable access network in a hotspot (the distinction between I-WLAN and "normal" WLAN networks can be made, for example, by a special SSID Values are accelerated).
- the search is terminated by the terminal and the terminal books temporarily in this I-WLAN.
- the I-WLAN allows the terminal to send a request via a network unit of the I-WLAN to the further network unit, for example in its home network. This can be achieved for example by special port filters in the access routers (access routers) or by the use of virtual LAN networks.
- Such a request can be made with a SIP, H.323, HTTP, HTTPS or other (secure) (signaling) protocol for security reasons, in which case the server authentication is sufficient.
- the terminal can log in to any WLAN and reach the further network unit, for example in the home network, for example via the Internet.
- a network unit for example an HTTP proxy server, in the I-WLAN or, for example, any cellular cellular network connected, uses source information such as, for example, country code MCC (Mobile Country Code) and network code MNC (Mobile Network Code) or x / y local number. Coordinates in the request message. Alternatively or additionally, this could also afford the terminal, if it has this information (eg by means of positioning methods via GPS (Global Positioning System)).
- the terminal or the application on the terminal can additionally send data or requirements such as the required bandwidths or the security of the access network to the further network unit, which can be taken into account by the further network unit in the selection of the communication networks.
- the further network unit receives this request and determines from the source data and the additional requirements of the terminal the optimum access network or communication network in the hotspot (coverage area of the communication network) which sends and sends preferred visited communication network VPLMN and optionally further intermediate networks or communication networks this information for example in the form of SSID and MNC / MCC in a response message back to the terminal.
- this information can be adapted flexibly according to country, location, tariff, network load and time.
- the terminal books depending on the received information in a communication network.
- the terminal for example a mobile computer, a computer, a mobile terminal, a mobile organizer, etc., could also interrogate the further network unit at periodic intervals or after changing the network configuration (possibly by changing the location) in order to possibly obtain more favorable connection coordinates , Authentication messages are sent according to the 3GPP standard over the visited mobile network specified by the home network operator. This eliminates a balance of existing mobile networks with those on the (U) SIM card stored networks. It could even continue to use existing (U) SIM cards. After successful authentication in the home network, for example, the terminal is able to establish a connection there via the visited mobile network and to use the services in the home network.
- This invention disclosure describes a method such as the use of a central, further network unit, for example a register unit, that simplifies and optimizes access to IP-based radio technologies such as WLAN for mobile operators and subscribers. The selection process is therefore accelerated and the resource consumption in the terminal is reduced.
- the described register unit also offers the possibility of storing further data which may be relevant to the terminal or the communication network for optimized roaming or handover.
- IP-based access networks can be specified by 3GPP or, more generally, simply connected to the 3GPP core network via a router. The invention will be explained in more detail with reference to an embodiment shown in a figure. Show
- FIG. 1 shows the method according to the invention on the basis of a simplified system architecture
- Figure 2 shows an inventive terminal
- FIG. 1 shows how a terminal, for example a mobile terminal, a mobile computer, a mobile organizer, a computer etc., temporarily logs into a communication network VPLMN 1 via the access network I-WLAN 1 in a hotspot and makes a request by means of the HTTPS protocol via a network unit HTTP Proxy of the communication network VPLMN 1 to another network unit WLAN DB of the home network HPLMN the terminal MS sends.
- the network unit HTTP Proxy can be a proxy server, a network unit of the access network I-WLAN 1, etc.
- the request could be supplemented by the network unit HTTP Proxy or the terminal MS with at least one information date, such as the country code, the network code of the currently used communication network, the location information regarding the current location of the terminal MS, etc.
- the terminal MS could additionally add to the request data or requirements, such as the required bandwidth, the security requirements for the communication network, etc.
- the further network unit WLAN DB for example a register unit, a database, a memory unit, etc. in the home network WLAN DB checks the request and sends a response with at least one information, for example the SSID identity of the preferred access network I-WLAN2 and the country code or Network identification number MNC2 / MCC2 of the preferred (visited) communication network VPLMN2.
- Temporary means that the terminal only in the communication network VPLMN 1 via the access network I-WLANl logs to ask the request to the other network unit can.
- the terminal MS posts depending on the information received in the communication network VPLMN2 (for example via the authentication network unit AAA Proxy WAG) via the access network I-WLAN2 (for example via the WLAN access point WLAN AP), authenticates itself to the home network HPLMN (for example in the authentication network unit AAA PDG) according to the 3GPP standard and then builds one A connection for performing communication to the home network HPLMN, for example, there to use certain subscribed services.
- the communication network or access network may be a cellular mobile radio network, a WLAN network, an IP network, an IWLAN network, etc. Also due to a network configuration or in periodic or non-periodic time intervals, the terminal MS could send such a request regarding at least one communication network to be used for communication to the other network unit WLAN DB and thus have the ability to always select the optimal for communication communication network.
- FIG. 2 shows a terminal MS for carrying out the method according to the invention with a receiving unit E, a transmitting unit S and a processing unit V.
