Problems solved by technology

[0005] The technical problem to be solved by the present invention is that the traditional access network architecture divides the cells, which makes the interference among the increasing number of base stations in the mobile communication network increasingly serious, making it difficult to schedule users. Performance management, load management and interference suppression cannot be effectively implemented in such a dense multi-level, heterogeneous hybrid network

Embodiment 1

[0045] This embodiment discloses a mobile communication access network architecture, such as figure 1 As shown, the architecture includes:

[0046] Antenna unit (AE): The antenna unit is responsible for transmitting and receiving wireless signals while providing coverage for user equipment (UE). The size of its transmission power determines the coverage of its user plane. The main characteristics of the antenna unit include resources such as transmission power, bandwidth, time slot, codeword, and spatial angle. In addition, the antenna unit has its own unique identification ID, and uploads its identification ID to the controller and the resource pool when accessing the network architecture to dynamically update the flow table maintained in the resource pool. When disconnected, The antenna unit also needs to send signaling to notify the controller and resource pool to delete its unique identification ID from the flow table so as to avoid allocating the antenna unit to the UE to pr...

Embodiment 2

[0073] This embodiment is directed to one of the hybrid networking conditions of Macro cell, Micro cell, Picocell, Femto cell, Relay Station, and WLAN. Mobile communication network architecture, such as image 3 Shown:

[0074] Different types of AEs are responsible for the functions of the antenna unit, CPEs are responsible for the functions of the centralized processing unit, the X2 interface is responsible for the functions of the interface between the CPEs, the X1 interface is responsible for the functions of the interface between the CPE and AE, and the control interface is responsible for all For the function of the control interface, the S-GW is responsible for the function of the serving gateway, the P-GW is responsible for the function of the data gateway, the OpenFlowController is responsible for the function of the controller, and the Resource Pool is responsible for the function of the resource pool.

[0075] Among them, various types of antenna units (Macro AE, Micro ...

Description

Technical field [0001] The present invention relates to the field of communication technology, in particular to a mobile communication access network architecture. Background technique [0002] With the gradual popularization of smart phones and tablet computers, users’ demand for wireless capacity has grown rapidly, and the cost of capacity gains that rely solely on innovations in wireless transmission technology is very high. Therefore, the current research focus on capacity growth is Meet users' growing capacity demands by deploying base stations more densely. In order to cope with complex scenarios such as indoor hotspots, new types of base stations have gradually emerged. Based on the existing macro base stations (Macro Cell), there have been micro base stations (Micro Cell), pico cells (Pico Cell), and femto base stations / homes. Base stations (Femto Cell / HomeeNB) and remote radio heads (RRH) and other base station forms, and relay stations (Relay Station) are also consider...
