Description
Technical field
The present invention relates to radio honeycomb communication technology, particularly relate to a kind of method and system determining interference source.
Background technology
Interference controls to be an important problem inside wireless telecommunication system.Under community is with frequency deployment scenario, presence of intercell interference can be more outstanding, and in alien frequencies situation, minizone also also exists the situation of adjacent frequency interference in addition.The method solving interference is different according to the generation scene of interference, and the descending interference typical method such as processing cell edge adopts channeling technology exactly.Can accomplish that the elimination disturbed minimizes by common solution interference method and making rational planning for for macro base station network.But along with the development of wireless technology, introduce the concept of Femto community, the introducing of Femto increases the complexity of wireless network, make the problem of interference more outstanding.Home eNodeB is exactly a kind of typical Femto community.Home eNodeB is a kind of small-sized, lower powered base station, be deployed in the indoor place such as family and office, Main Function is to provide higher service rate to user and reduce the expense used required for high rate services, making up the deficiency that existing distributed cellular radio communication system covers simultaneously.The advantage of Home eNodeB is economical, convenient, low-power output, plug and play etc., but is subscriber equipment due to it, disposes not through the network planning, so may introduce larger interference.
Be briefly described description for Home eNodeB, described method is adapted to any community.As shown in Figure 1 and Figure 2, femtocell user is connected to core net network by Home eNodeB Access Network, and wherein Home eNodeB Access Network is made up of jointly Home eNodeB and femto gateway.Here, the function that femto gateway mainly performs is: the fail safe of checking Home eNodeB, and the registration of process Home eNodeB and access control, be responsible for the data of exchcange core net and Home eNodeB.Home base station management system carries out operation maintenance management to Home eNodeB, according to Carrier Requirements configuration and control Home eNodeB, mainly realize configuration management function for Home eNodeB, comprising the examining of positional information, for Home eNodeB carries out parameter configuration, be mainly concerned with the parameter configuration of core net (CN) rank, the parameter configuration of wireless access network (RAN) side and the parameter configuration of radio frequency (RF).For the family base station system of evolution, Home eNodeB directly can not be connected with Mobility Management Entity (MME) by femto gateway; For the family base station system of 3G, Home eNodeB must be connected by femto gateway and then with CN.
The deployment of introducing Home eNodeB increases the disturbed condition between cellular cell.Due to Home eNodeB Numerous, so cannot demarcate completely with macrocell and other contiguous Home eNodeB frequency, and Home eNodeB is more under the coverage of macro base station, in addition the complexity that grouping management too increases interference is carried out for user.In order to carry out grouping management to user, Home eNodeB introduces the concept of closed signed user group (CSG) community, for CSG cell, only allows the user carrying out contracting with its CSG to access.The CAMEL-Subscription-Information list of user is all preserved, i.e. Allowed CSGList at subscriber equipment (UE) and network side.Whether UE can carry out judging whether oneself can access this community by the CSG mark of searching community in the Allowed CSG List oneself preserved; Network side can lead to Allowed CSG List to applying for that the UE of access carries out access control simultaneously.Owing to not having signing user to be linked into CSG cell, so in this case, CSG cell is in time Macro Cell covers will cause serious interference to the domestic consumer that cannot access.For the interference problem in wireless system, the existence that its research contents is not only confined to how to find to disturb, how to solve interference, determine interference source no less important.
According to the difference that interference produces, interference can be divided into uplink interference and descending interference two kinds.For the situation of uplink interference, adopt prior art, although the measurement of UE and the transmission power information of UE can be passed through in base station, predict UE under certain community and may create uplink interference to around adjacent area, but this measurement by UE judges to determine the method for interference source in order to realize interference, be decided by the algorithm of the parameter configuration that base station is initial and realization, whether the generation of true interference only has target side to know.So, this "ball-park" estimate accurately can not judge whether interference source present really creates interference, so also just cannot determine interference source accurately, and this kind of mode is only the judgement for the base station producing interference, although but cannot interference source be determined for receiving interference target BS.At present in the urgent need to a kind of solution determining interference source.
Prior art is that this judgment mode both accuracy is not high, is again one indirectly judgment mode, does not have specific aim by the measurement of UE to realize the judgement to interference; And the present invention is different from prior art, target network element directly receives interference indication information from source network element, using the foundation that the interference indication information received judges as target network element specific aim, to realize the judgement to interference.Owing to adopting the present invention, interference indication information can be supplied to target network element as with reference to information, as the foundation that specific aim judges, therefore, adopt the present invention, can precisely determining interference source be realized, greatly improve judgement precision when determining interference source, can judge accurately the real interference of current whether really generation.
