Abstract

The invention relates to a link operation method and a device in heterogeneous network handover. The method includes steps: receiving media irrelevant handover link operation request information with a specified link identifier; when a plurality of links exist among media irrelevant handover function MIHF entities, finishing the operation corresponding to the specified link according to the specified link identifier. The device comprises a link identifier receiving unit for receiving the media irrelevant handover link operation request information with a specified link identifier; a link operation unit connected with the link identifier receiving unit and used for operating the specified link. The method is used for solving the problems that the specified link can not be designated to handover when a service point MIH PoS of media irrelevant handover connected with a plurality of attachment points PoA carries out media irrelevant handover in present protocol. The proposal of the invention can improve media irrelevant handover efficiency to operate the whole handover flow normally.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a link operation technology in handover between heterogeneous networks. Background technique [0002] There are currently many networks with different architectures, such as the wireless local area network defined by the 802.11 protocol, the wireless metropolitan area network defined by the 802.16 protocol, and the third-generation cellular mobile communication network defined by the 3GPP (Third Generation Mobile Communications Standardization Partnership Project). It is said that it is difficult to conveniently switch and roam in heterogeneous networks under the condition of ensuring business continuity, so the 802.21 protocol is proposed for this purpose. The 802.21 protocol is defined by IEEE (Institute of Electronics and Electrical Engineers), and is a standard for optimizing handover in a heterogeneous network by providing link layer information and other related netw...
