The contents of the present document are subject to continuing work within the TSG and may change following formal TSG approval. Should the TSG mo
24、dify the contents of the present document, it will be re-released by the TSG with an identifying change of release date and an increase in version number as follows: Version x.y.z where: x the first digit: 1 presented to TSG for information; 2 presented to TSG for approval; 3 or greater indicates TS
25、G approved document under change control. y the second digit is incremented for all changes of substance, i.e. technical enhancements, corrections, updates, etc. z the third digit is incremented when editorial only changes have been incorporated in the document.

The key characteristics of 3GPP - WLAN Interworking are found in 3GPP TS 23.234 1. 4.2 Key characteristics of IP Networks Refer to 3GPP TS 29.061 4. 5 Interworki

44、234 1. 8 Interworking with PDN (IP) NOTE: The application of procedures in this subclause is not recommended if user authentication and authorisation with AAA server is required because of the following reason: In order to perform RADIUS Authentication, the user ID and password information have to b
45、e passed from WLAN UE to PDG. However, this function is missing in the IKEv2 protocol that 3GPP TS 33.234 16 refers in this release. In addition, user authentication and authorisation with AAA server will be standardised in release 7. 8.1 General Packet Domain with the 3GPP - WLAN Interworking acces
46、s shall support interworking with networks based on the Internet Protocol (IP). These interworked networks may be either intranets or the Internet. 8.2 PDN Interworking Model When interworking with the IP networks, the Packet Domain with the 3GPP - WLAN Interworking access can operate IPv4 or IPv6.
47、The interworking point with IP networks is at the Wi reference point, refer to scenario 3 in the clause Interworking Architecture in 3GPP TS 23.234 1. ETSI ETSI TS 129 161 V12.0.0 (2014-10)93GPP TS 29.161 version 12.0.0 Release 12The PDG for interworking with the IP network is the access point of th
48、e Packet Domain. In this case the Packet Domain network will look like any other IP network or subnetwork. Typically in the IP networks, the interworking with subnetworks is done via IP routers. The Wi reference point is between the PDG and the external IP network. From the external IP networks poin
49、t of view, the PDG is seen as a normal IP router. The L2 and L1 layers are operator specific. It is out of the scope of the present document to standardize the router functions and the used protocols in the Wi reference point. Interworking with user defined ISPs and private/public IP networks is subject to interconnect agreements between the network operators. No user data or header compression is done in the PDG. 8.2.1 Access to Internet, Intranet or ISP through Packet Domain The access to Internet, Intra
