What does RNC mean in wireless communication?

The Radio Network Controller (Radio Network Controller) is the main network element in the third generation (3G) wireless network, which is an integral part of the access network and is responsible for mobility management, call handling, link management, and handover mechanisms.

Also known as a wireless network controller. As a key network element of the 3G network, RNC is mainly used to manage and control multiple base stations under it. The whole functionality of the RNC is divided into two parts:

Radio resource management functions and control functions. Radio resource management is mainly used to maintain the stability of wireless propagation and the quality of service of wireless connections. The control function includes all functions related to the establishment, holding, and release of the wireless bearer.

Let's talk about RNC first.

Connection sequence: nodeb---rnc---msc(sgsn)--ss7 network. The device connected to the RNC downlink is NodeB (corresponding to the BTS in 2G), and the uplink connection is MSC (circuit domain) and SGSN (packet domain).

RNC role: I won't talk about any professional esoteric terms here, its role, control nodeb, transmit data, control and manage wireless networks.

Let's talk about MSC again

The connection sequence has been drawn earlier, the downlink is connected to RNC, and the uplink is connected to the SS7 network. MSC completes the management of RNC, mobile phone location management, wireless resource allocation, data link establishment, data transmission, etc.

The real mobile communication network is far more complicated than the connection sequence I drew above, and here is just a general meaning. If you want to discuss it in depth, please contact us often in the future.

The RNC is divided as follows:

RNC Planning.

It includes two parts: the estimation of the number of RNC and the planning of the RNC area. The former estimates the number of RNCs required based on factors such as the estimated number of nodebs, the number of cells, the cell capacity, and the interface flow weights (interface type and number of links), and is part of the wireless network estimate. The latter plans the coverage of an RNC based on the estimated number of RNCs and the coverage of each cell.

The RNC (Radio Network Controller) is the main network element in the third generation (3G) wireless network, which is an integral part of the access network and is responsible for mobility management, call handling, link management, and handover mechanisms.

First, the control position is different.

1. RNC: It is the main network element in the third-generation (3G) wireless network, and is an integral part of the access network, responsible for mobility management, call processing, link management and handover mechanism.

2. BSC: It is the control and management part of the base station subsystem, located between MSC and BTS, which is responsible for completing wireless network management, wireless resource management and monitoring and management of wireless base stations, and controlling the establishment, continuation and dismantling of wireless connections between mobile stations and BTS.

Second, the functions are different.

1. RNC: It mainly completes the functions of connection establishment and disconnection, switching, macro division and merger, wireless resource management and control, etc.

Third, the characteristics are different.

1. RNC: The supporting platform subsystem provides a distributed operation platform for isolating the underlying RTOS platform and multi-processor system for other subsystems, and completes the functions of process scheduling, timer management, memory management, inter-process inter-board communication, and device management.

2. BSC: Located between MSC and BTS, its task is to manage the wireless network, that is, to manage the wireless cell and its wireless channel, the operation and maintenance of wireless equipment, the business process of the mobile station, and provide the interface between the base station and the MSC.

Radio Network Controller (RNC) is a key network element in emerging 3G networks. It is an integral part of the access network and is used to provide mobility management, call handling, link management, and handover mechanisms.

Base Station Controller (BSC): BSC controls a group of base stations, and its task is to manage the wireless network, that is, to manage the wireless cell and its wireless channel, the operation and maintenance of wireless equipment, the business process of the mobile station, and provide the interface between the base station and the MSC. Simplify the equipment of the base station by centralizing the functions related to wireless control to the BSC as much as possible.

In the CDMA2000 system, the core network is also led out of the access network, and the first wireless network control part is called BSC.

Wireless is an access technology and is responsible for accessing mobile terminals; NetOptim is responsible for wireless network optimization.

After the wireless signal is processed by the base station equipment, it enters the core network through the transmission equipment for information exchange.

Wireless, network optimization, access, transmission, core.

Let's not talk about the definition, let's talk about it briefly:

Wireless: Wireless access is a mobile phone wireless network connection or something. Wifi or something:

Network optimization, adjust the transmission power, angle, etc., so that the signal is better accessed: it can refer to the mobile phone access to the base station (nodeb), or the base station access to RNC or something, which has a wide meaning.

Transmission: Signal transmission, data, voice transmission, etc.

Core: There is a core network, which refers to a large one in a broad sense, SGSN, HLR or something, and in a narrow sense, it refers to HLR, database, which is ** card, SIM or UIM card, IMSI or other information content, including various businesses you handle, card types.
