Embodiment Construction

[0048] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0049] Such as figure 1 Shown is a communication system in which a terminal switches between two hierarchical heterogeneous distributed base stations (or more hierarchical heterogeneous distributed base stations), where each hierarchical heterogeneous distributed base station includes a macro cell layer And a micro cell layer, the wireless nodes in the macro cell layer work in FDD mode, and the wireless nodes in the micro cell layer work in TDD mode. The macro cell layer of the hierarchical heterogeneous distributed base station A includes one wireless node 101a covering the macro cell 102a; and several wireless nodes 103a covering the micro cell 104a. The hierarchical heterogeneous distributed base station A further includes a baseband processing and control unit 105a, configured to perform baseband processing and control on the wireless no...

Abstract

The invention provides a method for switching a terminal among heterogeneous hierarchical distributing type base stations, comprising the steps: the terminal reports the measurement of a signal of a macrocell and the measurement of a signal of a microcell to a network; the network judges whether the terminal needs to be switched among the distributing type base stations or not according to the measurement reported by the terminal and a preset decision threshold; if the terminal needs to be switched among the distributing type base stations, the network confirms a duplex mode after terminal switch according to an available frequency spectrum resource of the target base station; the network transmits a switching control command to the terminal and carries the duplex mode after switch; and the terminal is switched according to the switching control command transmitted by the network. By using the invention, the terminal can be freely switched among the heterogeneous hierarchical distributing type base stations according to the use condition and a terminal state of network resources.

Description

technical field [0001] The present invention relates to the wireless access network technology in the communication network, and in particular to a method for realizing terminal handover among layered heterogeneous distributed base stations. Background technique [0002] The previous handover technologies of layered wireless access networks can be divided into two basic categories: intra-layer parallel handover and inter-layer vertical handover. Since the intra-layer parallel handover of layered wireless access networks can be realized by traditional handover methods, therefore, The handover technology of the existing layered access network mainly solves the problem of vertical handover between layers. [0003] Chinese patent application No. CN1503580 disclosed a mobile terminal scheduling method in a layered cell system on 2004.06.09. First, the speed of the terminal is measured; if the terminal is in a high-speed moving state, it is judged whether there is a higher-level c...
