Embodiment Construction

[0029] Embodiments of the present invention will now be described in detail with reference to the accompanying drawings. In the drawings, the same or similar parts are marked with the same reference numerals. In the following description, for the sake of brevity, known functions and structural features are not described in detail.

[0030] One of the most important problems for multicast services is switching connections. Embodiments of the present invention can solve the problems related to frequent handovers caused by multicast services used in micro cells, and can also solve problems caused by The overload problem caused by the high-speed multicast service provided. That is, users located in micro cells belonging to macro cells can use high-speed services by efficiently providing multicast services that must maintain a specific data rate according to the carrier-to-interference ratio (hereinafter expressed as C / I) of macro cells.

[0031] At the same time, the ratio of th...

Abstract

A method for providing a multicast service from a macrocell or a microcell to a mobile station in a mobile communication system having a hierarchical cell structure in which a given area is divided into at least one macrocell and at least one microcell overlapping with each other. The mobile station receives a multicast service by accessing the macrocell or the microcell according to a carrier-to-interference ratio (C / I) for the multicast service measured in a macrocell area and according to an existence or non-existence of a concurrent call currently in service. When there is no concurrent call currently in service, the mobile station receives the multicast service by accessing the macrocell in an area where the measured C / I is equal to or greater than a required C / I. However, when there is a concurrent call currently in service, the mobile station receives the multicast service by accessing the macrocell or the microcell based on the current cell and the C / I.

Description

technical field [0001] The present invention generally relates to a mobile communication system, in particular to a method for effectively providing multicast services in a hierarchical cell structure. Background technique [0002] In a mobile communication system, various cell types such as extra-large cells, macro cells, micro cells, and pico cells can be performed according to the service range and data rate defined in International Telecommunication Union-Telecommunication Standardization Sector (ITU-T) Q.1711. wireless access. And, according to the type of the cell, the service coverage is different. Similarly, the service coverage and data rate vary to some extent according to the level of mobile communication services, and the following examples illustrate the service methods of each cell. [0003] The extra-large cell uses the satellite communication network to provide broadband services covering a large area, and its cell radius is less than 100 to 500Km. Extra-l...
