Description
Technical field
The present invention relates to communication technical field is and in particular to method for handover control, device and communication system.
Background technology
The radio communication department of International Telecommunication Union（International Telecommunication Union R
Adio, ITU-R）By super 3 g mobile communication system（Beyond Third Generationin mobile co
Mmunication system, B3G）It is named as ternational Mobile Telecommunications AS（IMT-Advanced）.One side IMT-
Advanced proposes very high requirement to power system capacity, on the other hand supports the big wide frequency of IMT-Adva nced high power capacity
Spectrum typically can only find in higher frequency band, and the path loss of high band and penetration loss are all larger, the covering being difficult to realize.
In order to meet the demand to power system capacity and high covering of IMT-Advanced, in prior art, in proposing to be introduced into
Continue technology, and for improving power system capacity and covering, in legacy network, the wireless connection between base station and terminal is direct nothing
Line connects, that is, the network of single-hop.And introducing relaying technique is to increase one or more repeaters between the base station and the terminal,
The wireless signal being responsible for sending base station does one or many signal and forwards, until terminal receives this wireless signal.With simpler
Double bounce relaying as a example, a base station terminal wireless link is divided into base station wireless to two, terminal to relay station and relay station
Link, thus have an opportunity a second-rate link to be replaced with the preferable link of two quality, to obtain higher link
Capacity and more preferable covering.
