Problems solved by technology

[0004] In the case that the user-side device and the network-side device initiate MIH at the same time, it will cause an increase in the load of the Information Server (IS) (for example, before MIH is initiated The network-side device and the user-side device may need to query information from the IS. Generally, the information returned by the IS will be relatively long, that is, the capacity is relatively large, which increases the load of the IS), and it will also increase the load of the network, resulting in the failure of the MIH. The speed becomes slower; in addition, if each equipment manufacturer handles inconsistently when the user-side equipment and the network-side equipment initiate MIH at the same time, it will easily lead to the failure of MIH and cause serious impact on users

[0084] Figure 7 The flow chart of the first embodiment showing the priority negotiation method of the present invention includes the following steps:

[0085] Step S701: Obtain a set of devices that are pre-designated to initiate MIH with priority. Specifically: network-side devices, user-side devices, or a third party can pre-designate devices with priority to initiate MIH. For example, the above-mentioned set may only include network-side devices Pre-designated equipment (such as network-side equipment itself or user-side equipment), or only include equipment pre-designated by user-side equipment (such as user-side equipment itself or user-side equipment), or include devices pre-designated by network-side equipment , The device pre-designated by the user-side device. At this time, the device pre-designated by the network-side device and the device pre-designated by the user-side device may be the same or different, or may be initiated by a third-party server (such as a poli...

[0091] The flow of the priority negotiation method in the embodiment of the present invention can be completed on the network side device, or can be completed on the user side device, as follows Figure 8 , to further describe in detail the process of completing the priority negotiation method on the network side of the present invention, please refer to Figure 8 , Figure 8 The flow chart of the second embodiment showing the priority negotiation method of the present invention includes the following steps:

[0092] Step S801: Receive the MIH capability discovery request message of the user-side device, such as the MIH_Capability_Discover request message. The MIH capability discovery request message may carry the device identifier that the user-side device pre-designates to initiate MIH first, or may not carry a certain device identifier ( That is, the user-side device does not designate a device that initiates MIH first);

[0093] Step S802: Parse the identifier from the M...

[0125] When a network-side device that does not have priority initiates MIH due to some abnormal reasons (such as loss of network-side change request message, loss of state after network-side restart, etc.), please refer to Figure 13 , Figure 13 The flow chart of the first embodiment of the method of rejecting the MIH request of the present invention is shown, including the following steps:

[0126] Step S1301: the user-side device with priority receives the MIH request sent by the network-side device without priority, specifically, the MIH request may be MIH network-side candidate network query (MIH_Net_HO_Candidate_Query) request information;

[0127] Step S1302: The user-side device returns a response message to the MIH request to the network-side device, and the status value carried in the response message is Rejected. For example, the Status value carried in the response message may be 2 (Rejected), rejecting this request. Switch request.

Abstract

The invention discloses a priority consulting method which comprises the following steps: obtaining a device congregation which is preassigned to prior initiate media independent handoff (MIH); and according to a consultation principle, determining a device in the congregation and distributing a priority for prior initiating the MIH to the determined device. Correspondingly, the invention also discloses an MIH method, a priority consulting entity, an MIH device and an MIH system. By applying the embodiment of the invention, the condition of simultaneously initiating the MIH of a plurality of devices is avoided, thus the condition that the devices repeatedly initiate information inquiry to an information system (IS) in the same MIH is avoided so as to reduce the load of the IS and the loadof a network and accelerate the speed of the MIH. The problem that the MIH is failed because the devices simultaneously initiate the MIH is solved so as to improve the degree of satisfaction of users.

Description

technical field [0001] The present invention relates to the communication field, in particular to a priority negotiation method, a media-independent handover method, a priority negotiation entity, a media-independent handover device and a media-independent handover system. Background technique [0002] With the rapid development of mobile communication technology, many different wireless network access technologies have emerged. In order to switch between various heterogeneous networks and improve user experience, Media Independent Handover (MIH) is proposed. Based on the concept of MIH, MIH provides a switching capability between different link layer access technologies. It provides a unified interface based on different access technologies, trigger events and other information obtained based on the second layer. The switching process of network access technology. [0003] In the current MIH protocol standard, both user-side equipment and network-side equipment can freely ...
