A method for reserving the resource for the terminal

A technology for reserving resources and terminals. It is applied in the direction of network traffic/resource management, electrical components, radio/induction link selection and arrangement, etc. It can solve the problems of increased handover failure, inability to correspond to resources, and inability to guarantee, so as to increase the success of handover. The effect of the probability of

Problems solved by technology

However, in fact, in the method shown in Figure 1, there is no MIH_Handover_Prepare.request sent by the Serving AP to request the Target AP to reserve resources for the terminal, nor in the MIH_Handover_Prepare.response sent by the Target AP to the Serving AP after resources are reserved for the terminal. Carrying the identification information of the terminal will lead to two problems: the first problem is that the resources reserved by the Target AP for the terminal cannot be one-to-one corresponding to the terminal; the second problem is that if the resources reserved by the Target AP for the terminal are Another terminal seizes, it will increase the probability of handover failure
[0017] It can be seen from the above analysis that using the method shown in Figure 1 to reserve resources for the terminal in the handover area does not guarantee that the terminal can use the resources reserved for the terminal to conduct conversations after switching to the handover area, thereby increasing the chance of handover failure. probability

Embodiment Construction

[0036] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail by giving specific embodiments and referring to the accompanying drawings.

[0037] In order to solve the problem that the resources reserved for the terminal correspond to the terminal, so as to ensure that the resources reserved for the terminal will not be occupied by other terminals and increase the probability of successful handover, the present invention sends a handover request in which the Serving AP requests the TargetAP to reserve resources for the terminal. Carry the terminal ID. In this way, when the Target AP reserves resources for the terminal, it can determine which terminal the resource is reserved for, and the terminal can use the resources reserved by the Target AP for the terminal to conduct a session by sending an access request carrying the terminal ID to the Target AP. Thus, the process of swi...

Abstract

The disclosed method resource reserving for terminal comprises: the service entity sends switch request carrying terminal mark to the object entity, the latter stores the mapping relation between reserved resource and terminal mark. This invention adds switch success rate.

Description

technical field [0001] The present invention relates to a media independent handover (MIH, Media Independent Handover) technology of a wireless communication system, in particular to a method for reserving resources for a terminal in the MIH process. Background technique [0002] Changes in the channel environment of the wireless communication system, the movement of terminals, and the selection of different services may lead to handover between wireless communication system networks. In order to improve the performance and enhance the user experience of using the terminal, the MIH technology is proposed. The purpose of MIH in the wireless communication system is to realize seamless handover between heterogeneous networks in the wireless communication system. Switching between terminals and fixed terminals, collaborative application of terminals and network equipment, and switching between various heterogeneous networks of wireless communication systems. [0003] MIH is ma...
