Problems solved by technology

[0015] However, for the command service information supported by the MIHF entity, the prior art does not specify how to obtain it. Obviously, the initial MIHF entity does not know which command service information it should provide to the upper layer (MIH User)

Embodiment Construction

[0047] The present invention will be described in detail below with reference to the accompanying drawings.

[0048] The present invention provides a method for the MIHF entity to know the supported service information when the upper-layer entity wants to query the service information supported by the media-independent handover function entity in a heterogeneous network; and provides a method for the upper-layer entity to support the service information of the lower-layer entity Query method.

[0049] Wherein, the method for the media-independent handover functional entity to obtain the supported service information includes steps:

[0050] The media-independent switching function entity queries the service information supported by the lower layer (Lower Layer) entity;

[0051] Judging the service information provided by the media-independent switching functional entity for the upper-layer entity according to the query result;

[0052] Wherein, the service information is com...

Abstract

The present invention provides a method for a media-independent handover functional entity in a heterogeneous network to obtain supported service information, including steps: the media-independent handover functional entity queries the service information supported by a lower-level entity; and judges that the media-independent handover functional entity is The service information provided by the upper layer entity; wherein, the service information is command service information, or event service information and command service information. Through the present invention, the media-independent handover function entity is made aware of the command service information it supports, and can accurately notify the upper layer entity of the command service information and event service information it supports, thereby more effectively promoting terminal handover in heterogeneous networks .

Description

technical field [0001] The present invention relates to the field of mobile communication, and in particular to a heterogeneous network. When an upper layer entity wants to query the command service information and event service information supported by a Media Independent Handover Function (MIHF: Media Independent Handover Function) entity, the MIHF entity knows the supported A method for command and event service information; and a method for querying service information supported by a lower-level entity by an upper-level entity. Background technique [0002] With the rapid development of communication technology and the emergence of various new network technologies, how to solve the problems of handover and roaming between existing heterogeneous networks is very prominent. In order to solve the problems of users in the current IEEE (Institute of Electrical and Electronics Engineers; Institute of Electrical and Electronics Engineers) 802.11, IEEE 802.15, IEEE 802.16, 3GPP ...
