Embodiment Construction

[0034] figure 1 It is a diagram showing the topological structure of a super cell. In a super cell communication system, macro cells and micro cells form overlapping coverage. The coverage area of ​​a macro cell is much larger than that of a micro cell. But the resource consumption of the macro cell is obviously higher than that of the micro cell.

[0035] Radio resources in both macrocells and microcells can be allocated to data traffic and signaling traffic. However, since the total bandwidth is limited, the allocation ratio needs to be optimized. At this time, not only the service delay, service real-time rate, channel state, and interference level of the known technology are considered, but also the signaling overhead of the service and the mobility of the user requesting the service are considered.

[0036] For measuring the access threshold selection based on user mobility, it is necessary to select appropriate parameters through system optimization.

Abstract

Provided are a hyper-cellular communication system and a hyper-cellular communication method for associating a user to a macro cell base station or a micro cell base station. The hyper-cellular communication system includes: a gateway, which includes a user quality of service classification index table including two parameters, namely user mobility and signaling overhead; and a resource optimization function unit for making decisions on base station association and wireless resource allocation by referring to the quality of service classification index table.

Description

technical field [0001] The invention relates to a super cellular communication system and a super cellular communication method. Background technique [0002] The diverse services brought by smart phones and M2M applications have had a great impact on existing mobile cellular networks. In particular, the proportion of small business traffic in the network is increasing (instant message background business and M2M business), and the signaling overhead generated by them even takes up more than 60% of the resources on the air interface. The concept of super cellular is adopted here to simplify signaling and improve throughput. At present, there is a lack of comprehensive research on the mechanism of optimizing the utilization of system resources through the scheduling design of diverse services in mobile cellular networks. [0003] NTT Docomo proposed the concept of phantom cell in 3GPP RAN. They consider the separation and optimization scenarios of control plane and user pl...
