specific Embodiment approach 1

[0060] The threshold for the number of established tunnels of the IKE SA is preset in the PDG. When the WLAN UE initiates tunnel establishment, it is determined whether to assign a tunnel to the WLAN UE according to whether the number of established tunnels in the IKE SA reaches the set threshold. For example, Image 6 As shown, it specifically includes the following steps:

[0061] S11. The WLAN UE initiates a tunnel establishment request in an established IKE SA;

[0062] S12. The PDG judges whether the number of tunnels established in the IKE SA reaches the threshold of the number of tunnels established by the corresponding preset IKE SA. If not, proceed to step S3, and if yes, proceed to step S4;

[0063] S13. The PDG establishes a tunnel for the WLAN UE.

[0064] The PDG sends a tunnel establishment response to the WLAN UE, the tunnel establishment response accepts the tunnel establishment request of the WLAN UE, and adds 1 to the tunnel counter for the IKE.

specific Embodiment approach 2

[0073] The threshold for the number of tunnels established by the current user is preset in the 3GPP AAA Server. When the WLAN UE initiates tunnel establishment, it is determined whether to assign a tunnel to the WLAN UE according to whether the number of tunnels established by the current user reaches the set threshold. For example, Figure 8 As shown, it specifically includes the following steps:

[0074] S21. The WLAN UE initiates a tunnel establishment request in an established IKE SA;

[0075] S22, 3GPP AAA Server determines whether the number of tunnels established by the current user reaches the corresponding threshold, if not, enter step S23, if yes, enter step S24;

[0076] In this step, the number of tunnels that the current user has established can be obtained by counting the second counter set.

[0077] S23. The 3GPPAAA Server establishes a tunnel for the WLAN UE.

[0078] The 3GPPAAA Server sends a tunnel establishment response to the WLAN UE (possibly forwarded...

specific Embodiment approach 3

[0085] The threshold for the number of established tunnels of IKE SA and the threshold for the number of tunnels established by the current user is preset in the PDG. When the WLAN UE initiates tunnel establishment, according to whether the number of established tunnels in each IKE SA reaches the set threshold and the number of tunnels established by the current user Whether the threshold is reached to determine whether to allocate a tunnel for the WLAN UE, such as Figure 10 As shown, it specifically includes the following steps:

[0086] S31. The WLAN UE initiates a tunnel establishment request in an established IKE SA;

[0087] S32. The PDG judges whether the number of tunnels established in the IKE SA reaches the threshold of the number of tunnels established by the corresponding preset IKE SA. If not, proceed to step S33, and if yes, proceed to step S35;

[0088]S33. The PDG judges whether the number of tunnels established by the current user reaches the corresponding th...

Abstract

This invention discloses a method for setting up tunnels in WLAN and a system, in which, the method includes: A, a WLAN terminal starts up a request for setting up tunnels in an established IKE SA, B, judjing if the amount of the built tunnels in the IKE SA reaches to the corresponding first threshold value, if not, it enters into step C, if so, it enters into step D, C, setting up tunnels for the WLAN terminal, D, refusing setting up tunnels for the WLAN terminal.

Description

technical field [0001] The invention relates to the communication field, in particular to a tunnel establishment method and system in a wireless local area network. 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 such as IEEE 802.11a and ETSI BRAN Hiperlan2 both use the 5GHz frequency band, and the highest transmission rate can reach 54M...
