Problems solved by technology

For another example, the terminal only needs non-serving PoAs to return its own MIH capability, but these non-serving PoAs may broadcast the request message to other network elements, thus causing a network storm
[0019] To sum up, each network element in the current system usually cannot determine the sending method of the MIH_Capability_Discover.request message according to the needs, nor can it inform other network elements what to do after receiving the MIH_Capability_Discover.request message when forwarding the message

Embodiment Construction

[0058] The solution of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0059] The solution of the present invention firstly needs to add a request type field in the existing MIH_Capability_Discover.request message, and this field can be set with multiple identifiers as required, and each identifier corresponds to a processing scheme. In the preferred embodiment provided by the present invention, an optional field named ActionCode is added to Table 1 above. The message format after adding this field is shown in Table 2. The specific definition of this field is shown in Table 3.

Abstract

The method comprises: in the first, adding a MIH capability finding request type field into the capability finding request message, and setting the identifiers for different type requests. The method also comprises: a) when the net element in the system sends a capability finding request message, setting up a request type identifier currently required in the request type field; b) after receiving the capability finding request message, according to the identifier in the request type field of the message, the net element having MIHF executes relevant MIH capability finding process; c) the net element initiating the capability finding request gets the MIHF information relating to the relevant net element according to the processing result in step b.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method for realizing media-independent handover (MIH) capability discovery in heterogeneous network handover. Background technique [0002] At present, the development of communication technology is changing with each passing day, and various new access technologies emerge in an endless stream. Since the networks corresponding to various access technologies usually have their own suitable coverage and application scenarios, in order to realize ubiquitous communication services, multi-mode terminals supporting multiple access technologies emerge as the times require. A network using different access technologies is called a heterogeneous network. There are many kinds of heterogeneous networks, for example, the 802 networks provided by IEEE 802.3, IEEE 802.11 and IEEE 802.16, and the cellular networks provided by 3GPP and 3GPP2 are all heterogeneous networks. [0003] A ...
