example 1

[0050] Example 1 is based on the hierarchical structure of the Telecommunications Management Network (TMN) proposed by the International Telegraph Union (ITU), for example, image 3 As shown, it includes the network management system (NMS) and the network element management system (EMS). The NMS mainly completes the management of all network elements in the managed network, and the EMS mainly completes the management of one or more network elements. These network elements are usually From the same equipment vendor, the interface between NMS and EMS is a northbound interface (Itf-N), which can be standardized.

[0051] In this example, the NMS may add the NMS performance measurement statistical analysis function, which is optional, and optionally, the function realized by it may also be realized by a third-party tool.

Abstract

The invention provides a distribution method and a distribution system of a Un subframe. According to the method, a base station (DeNB) receives the property information allocated by a network management facility in advance, wherein the property information comprises the maximum numerical value of the Un subframe connected with DeNb and capable of being used by every radio navigator (RN); and the DeNB distributes Un subframe to every RN according to the maximum numerical value. According to the technical solution provided by the invention, the DeNb can reasonably distribute resource to RN, and Un subframe can be more effectively utilized.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a method and system for allocating Un subframes. Background technique [0002] Long-Term Evolution Advance (LTE-A for short) is an evolution version of LTE release-8. LTE-A adds a new network element relay node (Relay Node, referred to as RN). The eNB supporting RN is the Donor base station (Donor eNB, referred to as DeNB). The interface between RN and DeNB is Un interface, and the Un sub frame, the DeNB can only complete the data transmission process with the RN by scheduling physical resource blocks (Physical Resource Block, PRB for short) on the Un subframe. [0003] At present, 3GPP mainly discusses Type 1 RN, that is, RN has its own independent cell. DeNB can be connected to multiple RNs at the same time, and it is necessary to set the maximum number of Un subframes that can be used in one wireless frame for each RN. In each data transmission process, DeNB allocates Un t...
