Description
Technical field
The present invention relates to moving communicating field more particularly to the prisons of a kind of LTE network cell signal quality and link load
Examining system and its method.
Background technology
With the mobile communication demand growth of the mankind and technology development, the quality and efficiency of 2/3G communication networks cannot
Meet human demand, therefore 4G-LTE networks gradually start to apply.LTE（Long Term Evolution, long term evolution）Be by
3GPP（The 3rd Generation Partnership Project, third generation partner program）The UMTS organized to set up
（Universal Mobile Telecommunications System, Universal Mobile Communication System）The long-term of technical standard is drilled
Into formally setting up the project and start in the meeting of 3GPP Toronto in December, 2004.LTE system only exists packet domain.It is divided into two
Network element, EPC（Evolved Packet Core, evolution block core net）With eNode B（Evolved Node B, evolution Node
B）.EPC is responsible for core network part, and signaling process part is MME（Mobility Management Entity, mobile management are real
Body）, data processing division is divided into S-GW（Serving Gateway service webmaster）.ENode B are responsible for accessing mesh portions, also referred to as E-
UTRAN（Evolved UTRAN, the UTRAN of evolution）.
The bootings of UE mono-, which are introduced into, just searches state, by attachment and registration process, receives paging message and system information, completes
PLMN selections are synchronous with cell selection, initial downlink, into IDLE states.Before paging or high-rise initiation calling is received, UE
It is constantly in the state.In this state, any uplink physical channel is not had to connect between UE and E-UTRAN.UE is in the state
Listening broadcast channel safeguards the system information of update serving cell；The measurement of adjacent cell is performed, it is one preferably small when finding
Cell reselection is just carried out during area or when meeting cell reselection criteria.When the connection foundation request that UE receives high-rise configuration disappears
Breath, establishes reason according to connection and judges whether cell is prohibited.If cell is not prohibited, the RRC of UE is responsible for that radio resource is configured
And wireless channel, the initial random access processes of MAC are notified by primitive, establish uplink synchronous.When receiving, MAC is next to be connect at random
Enter the instruction message of response, notice high level establishes RRC connections, and establish SRB1.Initial security activates, and AS keys and phase is configured
Related parameter, and low layer is configured, association key required with integrity protection and parameter is encrypted.Responsible connection reconfiguration is put, and is built
Vertical SRB2 and DRBs, completes the wireless link between UE and E-UTRAN.When the Radio Link between UE and E-UTRAN is built
It erects after coming, normal data communication process can be carried out.
It can normally be communicated after user access network success, for wireless communication system, user understands root
A suitable cell to be chosen according to prespecified cell selection criterion to be resident, each cell has certain coverage area, this
A coverage area is related with the number of users in cell with the transmission power of eNodeB.But due to the mobility and nothing of user
The complexity of line network environment in itself, still may result in the failures such as call drop.
During deployment of LTE network, equipment or terminal is unstable or defect may also lead to that network quality is low, stability
Difference, therefore operator is badly in need of having signaling monitoring system that can be monitored, assess to main equipment, pushes the increased quality of network.
