Embodiment Construction

[0066] The preferred embodiments of the present invention will now be described in detail, and examples thereof are illustrated in the accompanying drawings. Whenever possible, the same reference numbers will be used throughout the drawings to indicate the same or similar parts.

[0067] In this application, the term mobile station (MS) may also be referred to as mobile subscriber station (MSS), mobile terminal (MT), mobile node (MN), terminal, and so on.

[0068] Figure 5 illustrates the structure of MIH events and link events according to an embodiment of the present invention. More specifically, the MIH event includes event information transmitted from the MIH to the upper management entity (UPE) or upper layer (or upper layer). Compared with conventional technology, this MIH event corresponds to an event trigger signal. The link event is transmitted from the lower layer (for example, the MAC layer or the physical layer) to the MIH. In addition, the link event uses primitives...

Abstract

A method of discovering at least one of a homogeneous and a heterogeneous network module to perform handover with in a wireless mobile communication network is disclosed. More specifically, the method includes establishing a network handover module for converging information from at least one network interface module associated with at least one of a homogeneous and a heterogeneous network handover module into a unified presentation and transmitting a broadcast request message from a mobile station (MS) to a source point of attachment (PoA) which transmits the broadcast request message to at least one interface module to identify whether the at least one interface module supports at least one of the homogeneous and the heterogeneous network handover module and a capability of the at leastone of the homogeneous and the heterogeneous network handover module. The method further includes initiating a timer for a specified time period when the broadcast request message is transmitted and receiving at least one response message from the at least one interface module via the source PoA prior to expiration of the timer, wherein the response message indicates that the at least one interface module supports at least one of the homogeneous and the heterogeneous network handover module and the capability of the at least one of the homogeneous and the heterogeneous network handover module.

Description

Technical field [0001] The present invention relates to a method of supporting handover, and in particular, to a method of supporting handover in a multi-mode mobile station. Although the present invention is suitable for a wide range of applications, it is particularly suitable for supporting handover of multi-mode mobile stations in a wireless mobile communication system. Background technique [0002] Generally, the goal of IEEE 802.21, which is currently underway for international standardization of media-independent switching between heterogeneous networks, is to enhance the convenience of users for mobile station (MS) devices by providing seamless switching and service continuity. The basic requirements here include MIH functions, event triggers (or event services), command services (CS) and information services (IS) defined as basic requirements. [0003] A mobile station (MS) may also be called a mobile subscriber station (MSS) or a mobile terminal, which is a multi-mode no...
