Embodiment 1

[0062] Such as figure 1 As shown, this embodiment provides a method for obtaining actions supported by the media link layer, including:

[0063] Step 11, the MIH user layer sends a media-independent handover capability query request command (MIH_Capability_Discover.request) to the MIHF, and the media-independent handover capability query request command includes the action list option supported by the link layer, when the action list option supported by the link layer When it is valid, query the actions supported by the link layer. When the action list option supported by the link layer is invalid, you do not need to query the actions supported by the link layer. In this embodiment, it is assumed that the action list option supported by the link layer is valid.

[0064] In order to obtain the actions supported by the link layer, it is necessary to extend the media-independent handover capability query request command, that is, add the action list supported by the link layer ...

Embodiment 2

[0153] Such as image 3 As shown, this embodiment provides a method for obtaining the actions supported by the media link layer by extending the link layer capability confirmation command. Refer to image 3 The method for obtaining actions supported by the media link layer in this embodiment is described.

[0154] Step 31, the MIHF sends a link layer capability query request command to the link layer.

[0155] In order to save the amount of data to be transmitted, the capability parameter option to be queried (list of supported events, list of supported commands, list of supported actions) may also be added to the link layer capability query request command. In this way, the format of the link layer capability query request command is as follows:

[0156] Link_Capability_Discover.request(

[0157] SourceIdentifier,

[0158] Supported Link EventList,

[0159] Supported Link CommandList,

[0160] SupportedIsQueryTypeList,

[0161] SupportedTransportList

[0162] Supporte...

Embodiment 3

[0181] Such as Figure 4 Shown, this embodiment through the newly defined Link_Action_Discover. request (link layer action query request command) and Link_Action_Discover. Confirm (link layer action query confirmation command), provides a method to obtain actions supported by the media link layer, see below Figure 4 The method for obtaining actions supported by the media link layer in this embodiment is described.

[0182] Step 41, the MIHF sends a link layer action query request command to the link layer.

[0183] Step 42, the link layer determines the supported actions.

[0184] Step 43, the link layer sets the determined action in the action list.

[0185] Step 44: The link layer sets the action list in the link layer capability confirmation command, and returns the link layer action query confirmation command to the MIHF.

[0186] In order to realize the embodiment of the present invention, a pair of new command primitives need to be defined for the MIHF layer to query...

Abstract

The embodiment of the invention provides a method and a device for obtaining actions supported by a link layer, which can solve the problem that the action capacity supported by a media link cannot be obtained in the prior art. The method includes the following steps: a media-independent switching functional entity transmits a request instruction for inquiring the link layer action to the link layer; the link layer determines and returns the action supported by the link layer to the media-independent switching functional entity by an action list. The device includes the media-independent switching functional entity and a link layer entity. According to the embodiment of the invention, an action list item supported by the link layer is added into the existing instruction primitive or newly-defined instruction primitive, so that the MIHF and MIH user layers can obtain the action supported by the link layer so as to lead the MIHF and MIH user layers to transmit a link action request to the link layer according to the link action supported by the link layer for carrying out effective operation to the link action, thereby improving the efficiency of the system.

Description

technical field [0001] The present invention relates to a communication technology, in particular to a method and device for obtaining actions supported by a link layer. Background technique [0002] With the development of communication technology, multiple communication networks coexist in a certain area, and multi-mode terminal equipment that can simultaneously support communication with multiple networks is also produced along with the needs of users. Due to differences in service areas and service capabilities of different networks, users hope that their mobile terminal equipment can realize media-independent switching between different media networks, so as to ensure the continuity of their services. In the prior art, such as in the P802.21 protocol, a framework for implementing media-independent handover services for multi-mode terminals is proposed. The main idea of ​​this architecture is to add a media-independent handover layer (MIH layer) between the second layer...
