Embodiment 1

[0221] Embodiment 1: In one embodiment, mobility domain information is included in FILS Discovery (FD) frames. One option is to introduce mobility domain information as a new information element into the FILS discovery frame. An example of a resulting FILS discovery frame is Figure 13 shown.

[0222] Therefore, refer to Figure 13 As an example, a fast initial link establishment FILS discovery frame 1400 for network signaling in a wireless communication network is provided, wherein the FILS discovery frame includes mobile domain information 1401 .

[0223] Another option is to introduce mobility domain information into the FILS discovery frame as a vendor specific element.

[0224] In this case, the vendor-specific elements may be formatted according to the directives and policies of the WFA for formatting vendor-specific elements introduced into the Wi-Fi Alliance program. exist Figure 14 An example of element formatting is shown in .

Embodiment 2

[0231] Embodiment 2: In another embodiment related to embodiment 1, the mobile domain information is a complete mobile domain element MDE. This would mean that the FD frame would include the MDE as another element in the list of currently present elements. An alternative is that the Mobile Domain Information only carries the Mobile Domain Identifier MDID field, which is one of the fields contained in the MDE. This would mean that the FD frame could include the MDID as another field or element into the list of currently present fields and elements. In the latter scheme, only 2 octets are added to the FD frame, as opposed to 5 octets including the entire MDE.

Embodiment 3

[0232] Embodiment 3: In another embodiment related to Embodiments 1 and 2, according to the two options described in Embodiment 2, the mobility domain information added to the FD frame is a hash value of MDE or MDID.

[0233] A hash function is any function that can be used to map numeric data of arbitrary size to numeric data of fixed size. The value returned by a hash function is called a hash value, hash code, hash sum, or simply hash.

[0234] There are several benefits to using hashed values, one of which is to reduce the size of the MDE and MDID during the hashing process. The reduced size means that a smaller amount of information is added to the FD frame and ultimately sent over the air. This further improves the performance of the network node 811 and the wireless communication device 830 .

Abstract

The proposed technology relates to the procedure of generating a fast initial link setup, FILS, discovery frame (1400) including mobility domain information (1401) and / or the exchange of such a frame between a network node and a wireless communication device, e.g. to enable the wireless communication device to determine whether to associate with the network node through a full authentication procedure or through a reduced authentication procedure.

Description

technical field [0001] The proposed technology generally relates to wireless communication and mobility in a wireless communication network, and more specifically, to a method for assisting a wireless communication device in determining an association procedure with a network node in a wireless communication network, and a method for Method for determining an association procedure with a network node, a method for generating a frame for wireless communication, a fast initial link establishment FILS discovery frame for network signaling, and corresponding network nodes, wireless devices, devices and Computer programs and computer program products. Background technique [0002] Wireless communication is growing at an increasing rate, and there are various wireless communication technologies including a wide range of wireless communication, and local area network communication technologies. [0003] For example, wireless local area network (WLAN) technology provides the basis ...
