Embodiment Construction

[0048] Exemplary embodiments of the present invention will be described below with reference to the accompanying drawings. In this exemplary embodiment, an LTE system is taken as an example. But those skilled in the art should understand that the scope of the present invention is not limited thereto. The schemes for automatically assigning physical cell identities in the example scenarios all fall within the protection scope of the present invention.

[0049] The scheme proposed by the present invention for automatically calculating the available PHY_ID for a cell or one or more newly added eNBs in the network has the following three key principles.

[0050] Principle 1: Store and update in real time the information about the associated cell of each cell that needs to be assigned a PHY_ID.

[0051] for cells x , and its associated cells can be defined as follows:

[0052] -cell x neighboring districts;

[0053] - collection {cell y}, cell y Indicates that the cell x a...

Abstract

The invention provides a method and device for automatically distributing physical cell identity (PHY_ID). The method comprises the following steps: respectively distributing corresponding PHY_ID for cells in a network and associated cells by utilizing a first, second and third sets; and updating a mapping table according the distributed PHY_ID, so that the mapping table finally comprises pairs of all the cells in the network and the associated cells, and the unique PHY_ID is respectively distributed to each cell in the network and the associated cell.

Description

technical field [0001] The present invention relates to the field of communication, more specifically, to a method and equipment for automatically assigning physical cell identifiers in a mobile communication system. Background technique [0002] Although the wireless performance of the current communication network has been greatly improved, from the perspective of commercial operation, operators require lower network construction and operation costs in order to provide users with lower-priced network services to win the market. The key to reducing operating costs is to reduce the manual network planning and optimization process and expand network automation functions. The automatic allocation of the physical cell identifier PHY_ID ((Physical Cell Identify)) is an important content of automatic planning and optimization of the current wireless network system. [0003] PHY_ID is an important configuration parameter of the cell. In actual networking, for example, there are ...
