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

[0034] Such as Figure 4 As shown, the service access notification process in this embodiment includes:

[0035] Steps 401-402: After the WLAN user terminal and the 3GPP AS complete the WLAN network access; immediately send to the 3GPP AS a message requesting establishment and authorization of a public channel for transmitting service access notifications; after the 3GPP AS receives the message, First judge whether there is a packet data gateway specified by the network, if yes, send the address of the specified packet data gateway to the WLAN user terminal currently sending the request, otherwise, the 3GPP AS sends the address of the packet data gateway to which the WLAN user terminal currently sending the request belongs sent to the WLAN user terminal.

[0036] Steps 403-404: After the WLAN user terminal obtains the address of the packet data gateway, establish a public channel for transmitting service access notifications according to the address and the corresponding pack...

Embodiment 2

[0046] Such as Figure 5 As shown, in the present embodiment, the SMS service unit is used as the service notification unit, and the service access notification process in the present embodiment includes:

[0047] Steps 501 to 502: are basically the same as steps 401 to 402 in Embodiment 1, except that the WLAN user terminal applies to the 3GPP AS to establish an SMS service channel, and the 3GPP AS returns the business service unit to the WLAN user terminal after receiving the application address, the business service unit in this embodiment is an SMS service unit.

[0048] Step 503: After receiving the IP address of the SMS service unit, the WLAN user terminal directly establishes a public channel for transmitting service access notifications with the SMS service unit through the packet data gateway to which it belongs. After the public channel is established, the WLAN user terminal needs to identify the user terminal The relevant information such as the IP address correspond...

Embodiment 3

[0053] Such as Figure 6 As shown, in this embodiment, the PUSH service unit is used as a service notification unit, and the service access notification process in this embodiment includes:

[0054] Steps 601 to 602: are exactly the same as steps 401 to 402 in Embodiment 1, except that after the 3GPP AS receives the connection establishment request, it returns the address of the business service unit to the WLAN user terminal. The business service unit in this embodiment It is the PUSH service unit.

[0055] Steps 603-605: are exactly the same as steps 503-505 in the second embodiment, except that the SMS service unit in the steps is replaced by the PUSH service unit.

[0056] Similarly, after step 605, step 606 may be further included: after receiving the service access notification, the WLAN user terminal may automatically activate service A, or choose to activate service A or reject service A, and the specific implementation process is the same as step 409.

Abstract

The present invention discloses a method for transmitting service data to wireless local area network (WLAN) users. A service notification unit is set in the network for use in transmitting service access notices to WLAN users. After accessing the network, a WLAN user terminal immediately establishes a continuous connection between itself and the network as a common channel for transmitting service access notices. Before a service serving unit transmits service data to a WLAN user terminal that has no direct connection with the serving unit, the method comprises as well: the said service serving unit sending a service access notice to the said service notification unit; after receiving the service access notice, the said service notification unit inquiring and acquiring the routing information of the established common channel , and sending the service access notice to the said WLAN user terminal via the established common channel in accordance with the acquired routing information. In accordance with this invention, service access notices can be sent to user terminals when the user terminals have no direct connections with the service to be accessed.

Description

technical field [0001] The invention relates to a service access technology in a wireless local area network, in particular to a method for sending service data to a wireless local area network user by actively establishing a service access notification sending channel by a 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 data transmission rate of 802.11g can reach 54Mbps. Other new technologies s...
