HNBID (Home evolved node B identifier)

HNBID (Home evolved Node B identifier) is a unique identifier assigned to a Home evolved Node B (HeNB) in a mobile network. A HeNB is a small cell base station that is typically deployed in a residential or small business environment to improve coverage and capacity in a specific area.

In a mobile network, the HeNB connects to the core network via the Home NodeB Gateway (HNB-GW). The HNB-GW provides a secure connection to the core network, allowing the HeNB to provide mobile services to users in the area it covers.

The HNBID is an important element in the identification and management of HeNBs in the mobile network. The HNBID is a 32-bit value that uniquely identifies each HeNB in the network. The HNBID is allocated by the mobile network operator and is used by the core network to manage the HeNB and the mobile devices connected to it.

The HNBID is composed of three parts: the operator ID, the region ID, and the HeNB ID. The operator ID identifies the mobile network operator that owns the HeNB. The region ID identifies the geographic area where the HeNB is located, and the HeNB ID identifies the specific HeNB within the region.

The HNBID is stored in the HeNB and is transmitted to the HNB-GW during the initial setup process. The HNB-GW uses the HNBID to identify the HeNB and to establish a secure connection between the HeNB and the core network. The HNBID is also used by the core network to manage the HeNB, including configuration, monitoring, and troubleshooting.

In addition to the HNBID, the HeNB is also assigned a physical cell ID (PCI), which is used to identify the HeNB and its associated radio resources. The PCI is a 16-bit value that is assigned by the HeNB during the initial setup process. The PCI is used by mobile devices to identify the HeNB and to access its radio resources.

The HNBID and PCI are important elements in the management of HeNBs in a mobile network. They allow the network operator to identify, configure, and manage HeNBs in a secure and efficient manner. They also allow mobile devices to access the radio resources of the HeNB and to receive mobile services in areas where coverage and capacity are limited.

In conclusion, the HNBID is a unique identifier assigned to a HeNB in a mobile network. It is composed of three parts, including the operator ID, region ID, and HeNB ID, and is used by the core network to manage the HeNB and the mobile devices connected to it. The HNBID, along with the PCI, are important elements in the identification and management of HeNBs in a mobile network, allowing for efficient and secure access to mobile services in areas with limited coverage and capacity.
