Problems solved by technology

[0009] In traditional handover measurement control messages, the measurement objects of the designated UE are generally all or some cells in the base station’s neighbor cell list. These designated cells for measurement have not been deleted (including cells with poor state information), that is, the designated UE The measurement object is blind

Embodiment Construction

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only an illustration of the present invention.

[0034] The embodiment of the present invention provides a mobile communication system handover measurement control method, which can avoid taking cells with heavy load, excessive interference or poor communication link quality as UE measurement objects, and improve the handover success rate.

[0035] image 3 It is a schematic flow chart of the handover measurement control method of the embodiment of the present invention, specifically including steps:

[0036] Step 1. When the macro cellular network is initialized, a neighboring cell information list is generated and periodically maintained in each RNC. The neighbor cell information list includes, but is not limited to, frequency points, ...

Abstract

The invention discloses a handover measurement control method for a mobile communication system. 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 [0001] The invention relates to the method of measurement control and Uu interface (air interface) message construction in the third generation UMTS (Universal Mobile Communication System) and its evolution system, especially the handover measurement control method of the mobile communication system. Background technique [0002] Time Division-Synchronous Code Division Multiple Access (TD-SCDMA) is a 3G wireless transmission scheme for the third generation mobile communication system submitted by China to the International Telecommunications Union (ITU) in 1998. It is a brand new mobile communication system that adopts TDD mode. At the same time, a series of high technologies such as synchronous CDMA, smart antenna, software radio, relay switching and dynamic channel allocation are adopted. Compared with WCDMA and CDMA2000, TD-SCDMA has obvious advantages such as no need for paired frequency bands, high spectrum utilization, strong flexibility, suitable for s...
