Problems solved by technology

[0008] However, if the user terminal has connected to the WLAN network at this time, but has not yet established a channel connection with the network service through the PDG, or has not established a channel for a certain service or a certain group of services, and there is a service need Send data to the user terminal, including two situations: the user terminal has connected to the WLAN network, but only connected to WLAN local services such as local internet / intranet; the user terminal has connected to the WLAN and activated some services based on 3GPP PS , but does not access the service that needs to send data to it, there is currently no plan to notify the user terminal to establish a connection and perform service interaction

Embodiment 1

[0043] This embodiment is an example of the process of sending information to the destination user terminal by the packet data gateway using the private network identification + IP address method. In this embodiment, the access public land mobile network (VPLMN) allocates the private IP address. In this embodiment, the network data sending unit is the packet data gateway, the user authentication, authentication and charging unit and the user address registration query unit are both 3GPP AS, the user address allocation unit is WAG1, and the private network data gateway is WAG2. Such as Figure 5 As shown, the process of sending information from the network to the destination user terminal in this embodiment includes:

[0044] Steps 501-503: When a WLAN user terminal accesses the 3GPP-WLAN interactive network, it first completes the access authentication of the WLAN network with the 3GPPAS; then WAG1 in the local PLMN network allocates a private network for the user terminal cur...

Embodiment 2

[0051] This embodiment is an example of the process of sending information to the destination user terminal by the packet data gateway using the private network identifier+IP address method. In this embodiment, the WLAN access network allocates the private IP address. In this embodiment, the network data sending unit is a packet data gateway, the user authentication, authentication and billing unit and the user address registration query unit are both 3GPP ASs, the user address allocation unit is a WLAN access network, and the private network data gateway is a WLAN private network data gateway. like Image 6 As shown, the process of sending information from the network to the destination user terminal in this embodiment includes:

[0052] Steps 601-603: When a WLAN user terminal accesses the 3GPP-WLAN interactive network, it first completes the access authentication of the WLAN network with the 3GPP AS; IP address: after the user terminal currently accessing the network obta...

Abstract

The invention discloses a method that network transmits information to user terminal, including: as each wireless local area network (WLAN) user terminal accesses to the WLAN, the WLAN allocates a private IP address of private network to the current access user, and the user terminal registers the allocated private IP address and identification of a private network where it is; as the network transmits information to WLAN user terminal which does not build a direct connection with it, it sends information to the user terminal according to the address information registered by the user terminal. It transmits information to user terminal on the condition that the user terminal does not build a direct connection with the current network data-transmitting unit.

Description

technical field [0001] The present invention relates to the information transmission technology in the intercommunication network between wireless local area network (WLAN) and mobile communication network, especially a method for mobile communication network to send information to user terminal according to the private IP address assigned to WLAN user terminal. Background technique [0002] As users have higher and higher requirements on wireless access rates, a wireless local area network (WLAN, Wireless Local Area Network) emerges at the historic moment, which can provide high-speed wireless data access within a small range. Wireless local area network includes a variety of different technologies. A technical standard that is widely used at present is IEEE802.11b, which uses the 2.4GHz frequency band, and the maximum data transmission rate can reach 11Mbps. IEEE 802.11g and Bluetooth (Bluetooth) technology are also used in this frequency band. , Among them, the highest da...
