Problems solved by technology

However, this does not take into account the signal coverage of each cell, which may seriously affect the system performance
[0005] For example, if the signal coverage capability of the low-load cell is weaker than that of the balanced users, or there is no signal coverage, then after the user is balanced to the low-load cell, the signal will be poor and the service cannot be used smoothly , at this time, the low-load cell cannot guarantee the user's service quality, and in severe cases, the user will be in a frequent ping-pong equilibrium state, that is, it will be repeatedly balanced between the low-load cell and the heavy-load cell. Obviously, this will make the balanced user The business cannot be used normally, which seriously reduces the performance of the system and affects the stability of the system

Embodiment Construction

[0023] In order to achieve effective load balancing in the LTE system, in the embodiment of the present invention, the management device can administer the eNBs in the network through the performance data reported by each eNB acquired in the OMC (Operation and Maintenance Center) database. Real-time monitoring of the load status of each community, and determine that when the performance indicators selected for monitoring within the preset monitoring period meet certain conditions, the load balancing optimization analysis is automatically triggered, and then load balancing adjustments are made to each community according to the analysis results.

[0024] In the embodiment of the present invention, the management device may be a system background server, or an independently configured device for load balancing adjustment, or a certain functional module in O&M, which will not be described here.

[0025] Preferred embodiments of the present invention will be described in detail bel...

Abstract

The invention relates to the field of communication, and discloses a method and device for realizing the load balance in a long term evolution (LTE) system, which are used for improving the system performance. The method comprises the steps of: determining key performance indicators (KPI) of all communities according to performance indicators, determining the communities which have the probabilities that the KPIs are higher than a set first performance indicator threshold in a monitoring time and reach a preset probability threshold as communities to be balanced, screening N adjacent communities with KPIs lower than a preset second performance indicator threshold respectively according to each community to be balanced, and carrying out load balancing adjustment between each community to be balanced and the corresponding N adjacent communities, wherein N is a positive integer which is more than 1. Consequently, the load balancing efficiency is increased, meanwhile, the service quality of the communities with low loads can be effectively ensured, so that balanced users can normally use the service, accordingly, the system service quality is ensured, the whole system performance is effectively improved, the safety, stability and capacity of the system are increased, and the system reaches an overall optimization state.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method and device for realizing load balancing in an LTE system. Background technique [0002] In the LTE (Long Term Evolution, Long Term Evolution) communication system, the increase in cell load will affect the index performance of user services. If the load of the cell cannot be reduced in a timely and effective manner, when the system load increases to the warning line of the system, it will The performance of the system deteriorates sharply and even causes the system to crash; at the same time, due to the uneven load distribution, for heavy-loaded cells, the resources they have are relatively scarce, which can easily lead to insufficient guarantee of user service quality, and for low-loaded cells However, there is a waste of resources. [0003] For the above questions, see figure 1 As shown, at present, the solution adopted in the LTE system is: each eNB reports its own...
