(HomeGateway), wireless LAN system and method. Background technique

Currently, for fixed and mobile network convergence, FMC strategy is increasingly valued by telecom operators and equipment manufacturers. Without FMC, voice services will continue to move from fixed networks to mobile networks.

The present invention utilizes the wireless local area network system of FIG. 2 to implement a method for merging fixed and mobile networks, including the following steps:

First, the wireless LAN is constructed indoors based on the indoor gateway of the universal mobile communication system, and the protocol stack, the database, the rule base, the transceiver, and the public mobile network interface are arranged in the indoor gateway, and the data required for the local self-organizing network capability is stored in the database. The data forwarding rule information in the data service processing is stored in the rule base, and the data conforming to the rule requirements will not be transmitted to the public mobile network;

Then, receiving signaling and data of the indoor mobile public network interface of the indoor gateway, processing the signaling and the data by using the protocol stack, determining which are based on the self-organizing network data saved in the query database and the data forwarding rule information saved in the rule base. Signaling and services need to be done locally, and which signaling and services require the processing of public mobile networks;

Exchange IP data over the Internet or a private network; Finally, the determined signaling and services requiring public mobile network processing are forwarded to the public mobile network through the public mobile network interface.

Referring to FIG. 3, a voice call process flow according to an embodiment of the present invention,

First, the signaling and data obtained from the Uu interface or the Iub interface include signaling and data from the UE to the base station, signaling and data from the UE to the RNC, and signaling data from the UE to the CN (core network). The protocol resolution will be first performed inside the indoor gateway (step 301), and then the cell selection process or the handover process is performed. The device needs to find those users who are allowed to camp in the cell, and only the users allowed by the device are allowed to reside in the present. Cell (step 302). Next, the HGW rule base and the database are queried (step 303), and it is judged whether the user who initiated the call and the called user are camped on the HGW cell (step 304 and step 305), only when the user who initiated the call and the called user reside. In the HGW cell, the call process is completed inside the HGW, that is, the simplified 3GPP protocol stack is executed on the HGW (step 306), so that the call flow is completed inside the HGW (step 308), and not forwarded to the public mobile network through the Iub port. RNC and CN; otherwise, as long as the user who initiated the call and the called user do not reside in the HGW cell, they need to forward to the RNC and CN of the public mobile network through the Iub interface, and execute the public network protocol stack (step 307). The 3GPP public network completes the call flow (step 309).

Referring to FIG. 4, the data session process flow is performed in the embodiment of the present invention. Here, the data session process between the UE and other UEs is similar to the voice service call flow shown in FIG. 3, and details are not described herein. In the following, only the data session process in which the UE shares data with the portable device or the UE accesses the Internet is briefly described.

First, the signaling and data obtained from the Uu interface or the Iub interface, including the signaling and data from the UE to the base station, the signaling and data from the UE to the RNC, and the signaling data from the UE to the CN, will first be in the indoor gateway. Internally performing protocol parsing (step 401), and then performing a cell selection process or a handover procedure, the device needs to find those users who are allowed to camp in the cell, and only the user allowed by the device is allowed to camp in the cell (step 402). . Next, the HGW rule base and database need to be queried (step 403) to determine whether the UE shares the database with the portable device or accesses the Internet (step 404). If the UE shares the database with the portable device (step 405), it is necessary to determine whether the UE and the portable device are in the same indoor WLAN (step 407). If the same WLAN is under, the data session process can be completed within the HGW, that is, in the HGW. Performing a simplified 3GPP protocol stack (step 409), thereby completing the data session flow (step 411) within the HGW, and not forwarding to the RNC and CN of the public mobile network through the lub interface; otherwise, it is required to switch to the lub interface (step 410), The public network protocol stack function is executed (step 410), and the data service session flow of the UE and the portable shared database is completed through the 3GPP public network (step 412). If the UE accesses the Internet (step 406), it is determined whether the Internet IP address accessed by the UE falls within an IP address range that allows direct access to the Internet through the HGW (step 408). If yes, the process proceeds to step 409, where the data is completed within the HGW. The session process is not forwarded to the RNC and CN of the public mobile network through the lub port. If the Internet IP address accessed by the UE does not belong to the IP address range that allows the HGW to directly access the Internet, the public network protocol stack function is executed through the lub interface (step 410), and then the data service session flow of the UE accessing the Internet is completed through the 3GPP public network. (Step 412). Industrial applicability
