In the method, by virtue of architectural characteristic of a TD-SCDMA (Time Division-Synchronous Code Division Multiple Access) system, RNCs (Radio Network Controllers) can carry out information interaction via an Iur interface or a core network (CN) and maintain a neighboring cell information list in real time; and according to the maintained neighboring cell information list, the RNCs only configure the cells with light load, small interference and good link quality in the neighboring cell information list in a measurement control message issued to UE (User Equipment), while the cells with severe or worse information are not used as measuring objects of the UE so as to prevent the cells with insufficient available resource, too big interference or poor communication link quality from being used as the measuring objects, which decreases number of the cells measured by the UE, reduces measuring burden of the UE, lowers time cost during the measuring process, realizes prior optimization for a measuring object list of the UE to a certain degree and reduces trial times during the handover process so as to reduce handover delay and drop call rate during the handover process and improve handover success rate.
Description
Technical field
The present invention relates to measure in third generation UMTS (universal mobile telecommunications system) and the evolution system thereof the method, particularly mobile communication system handover measurement control method of control and Uu mouth (air interface) message constructing thereof.
Background technology
Time Division-Synchronous Code Division Multiple Access (TD-SCDMA) is Chinese the 3rd 3G of the third-generation mobile communication system wireless transmission scheme of submitting to International Telecommunication Association (ITU) in 1998; It is a kind of brand-new mobile communication system; Adopt tdd mode, and adopted a series of new and high technologies such as synchronization CDMA, smart antenna, software radio, baton handover and dynamic channel allocation simultaneously.With respect to WCDMA and CDMA2000, TD-SCDMA has does not need that paired frequency band, the availability of frequency spectrum are high, flexibility is strong, be fit to symmetry and obvious advantage such as asymmetric data is professional, the system equipment cost is low.
As shown in Figure 1, be the structural representation of the wireless access network of TD-SCDMA system.Wireless access network (UTRAN) is made up of Radio Network System (RNS).A RNS comprises a radio network controller (RNC) and one or more NodeB.NodeB links to each other with RNC through Iub interface.RNC is responsible for the switching controls of UE, the combination/functions such as division of grand branch collection information flow between the different N that provides support odeB.RNC between the RNS links to each other through the Iur interface.The Iur interface can directly link to each other through the physical connection between the RNC, also can link to each other through any suitable transmission network.
Hard-switching technology be at present the most basically, the simplest handoff technique.In the TD-SCDMA system, its direct-cut operation mechanism is with reference to the handover mechanism of existing gsm system, i.e. Mobile Assisted Handover mode.Functions such as measurement that main guiding theory is switching and processing are distributed in each mobile device, are promptly measured the signal strength signal intensity of this base station and peripheral base station by travelling carriage, measurement report are analyzed and are handled to RNC, thereby make relevant decision-making of switching.Handoff procedure can be divided into following three steps: 1) handover measurement; 2) switch decision; 3) switch execution.Handover measurement is accomplished by UE, RNC and Node B, and switch decision carries out in RNC, switches to carry out under the common cooperation of UE, RNC and Node B to accomplish.
In wireless communication system, because UE (user terminal) is in mobile status, for grasping state and the channel circumstance thereof of UE; And carry out corresponding decision; For example switch, change Radio Resource etc., network need be controlled UE one tittle is measured, and requires UE to report by specific mode.Measuring control, is the important means of keeping the Radio Link reliability.
Measurement Control (measuring control) message, by RRC (Radio Resource control) agreement structure, and defeated in the Uu oral instructions.Article one, construct good Uu mouth message by agreement, after MAC (medium are got involved control) layer and the processing of RLC (Radio Link control) layer protocol, be converted into binary bit stream, deliver to the physical layer of transmitting terminal.In physical layer, this bit stream is through a series of processing, comprise add CRC, piecemeal or cascade, chnnel coding, interweave, the segmentation of multiplexing, the physical channel of rate-matched, transmission channel, subframe segmentation etc.; Be mapped to physical channel at last, again via aerial emission.
In cellular system, UE will measure the NodeB of this sub-district and adjacent sub-district.As shown in Figure 2, be a typical example of measuring control flow.UTRAN constructs message, and sends measurement control message to UE, i.e. Measurement control message comprises information such as the measurement target tabulation that is used to indicate UE to measure, measuring amount, measurement report rule in this Measurement control message; UE stores the content of this message, or according to this message content local canned data is made amendment; And the specified measuring amount of message measured, by the report rule of message appointment, send measurement report message, i.e. Measurement Report message to UTRAN.
