Embodiment Construction

[0027] Below in conjunction with accompanying drawing, the present invention will be further described:

[0028] like figure 1 as shown, figure 1The long-term scale context-aware SON architecture that this method relies on is implemented. The long-term environment-aware SON entity is constructed on the network side, and the UE location estimation module is enabled on the network side and UE location measurement is performed as an aid to obtain environmental information. The long-term environment-aware SON entity includes the following sub-modules: environment-aware SON interface for information exchange with other protocol layers, environment information collection module, environment characterization processing module, environment characteristic information database, and SON configuration self-optimization module (the module consists of an optimization algorithm library and a network self-configuration module). Through the large-scale environment-aware SON module interface...

Abstract

The invention discloses a handover parameter self-configuration method based on high frequency handover failure region sensing in a heterogeneous cellular network, and belongs to the technical field of wireless communication. According to the method, an environment sensing SON (Self-Organizing Network) entity is constructed at a network side; handover event information in a network environment is collected for a long time through an RRC layer; the information is characterized, thus obtaining a handover performance geographical distribution table; when the network is operated, an SON takes the distribution table as an optimization reference, generates specific measuring parameters for UE entering into a high frequency HOF (handover failure) region and sends the parameters to the UE through the RRC layer, thus modifying the measuring configuration of the UE and increasing the handover performance of the UE in the high frequency HOF (handover failure) region.

Description

technical field [0001] The invention belongs to the technical field of wireless communication, and relates to a handover parameter self-configuration method based on high-frequency handover failure area perception in a heterogeneous cellular network. Background technique [0002] During the evolution of the mobile communication system, due to the popularization of various smart terminals, the data traffic will experience a blowout growth. In the future, data services will be mainly distributed indoors and hotspots. Therefore, the dense heterogeneous small cell network will become one of the main means to improve network coverage and greatly increase system capacity. The increasingly dense network deployment also makes the network topology more complex. Mobility enhancement solutions based on terminal capability enhancement, rapid cell discovery, intensive inter-cell collaboration, and self-organizing network SON that comprehensively considers all aspects are currently hetero...
