Description
Technical field
The present invention relates to wireless communication field, particularly relate to a kind of method that network mobility optimizes.
Background technology
Along with the development of wireless mobile telecommunication technology, two-forty, low latency, low cost are proposed more by people
Carry out the highest requirement.LTE (Long Term Evolution) project creates the most in this context,
Pursue higher peak rate and shorter propagation delay time.
The main performance target of LTE project includes: can provide descending in 20MHz spectral bandwidth
100Mbps, the peak rate of up 50Mbps, improve the performance of Cell Edge User, improves community and holds
Amount；Reducing system delay, the internal unidirectional transmission time delay of user plane, less than 5ms, controls plane from sleep shape
State is to state of activation migration time less than 50ms, and the migration time from resident state to state of activation is less than
100ms；Support the MPS process of 100Km radius；Can provide for 350Km/h high velocity mobile users
> access service of 100kbps；Support paired or non-paired frequency spectrum；Support bandwidth varying, maximum 20M band
Wide.
LTE uses the simple squamous being made up of access network eNB (Evolved Node B) in the network architecture
Changing All-IP Network Architecture, this structure is conducive to simplifying network and reduction postpones, it is achieved that low time delay, low
Complexity and the requirement of low cost.ENB include physical layer, MAC (Medium Access Control) layer,
RRC (Radio Resource Control), scheduling, Access Control, carrying control, access mobile management
Deng.Grid (Mesh) mode direct interconnection will be used between eNB and eNB, progressively level off to typical IP
Broadband network structure.
In physical-layer techniques, LTE have employed OFDM (Orthogonal Frequency Division
Multiplexing), advanced for MIMO (Multiple Input Multiple Output) etc. Radio Transmission Technology
And link circuit self-adapting scheduling mode of based on channel and interference coordination technique.Further increase the speed of user
Rate and cell throughout, improve cell-edge performance.
Along with the development of wireless communication technology, and the further serious hope of low time delay, two-forty, at LTE-A
The technology that stage introducing is new, such as carrier aggregation CA (Carrier Aggregation), relaying Relay technology,
Multipoint cooperative CoMP (Coordinated Multipoint), eICIC (Enhanced Inter-Cell
Interference Coordination) etc. wireless technology.
Carrier aggregation CA was incorporated in LTE-A in the R10 stage, supported the carrier aggregation of most 5 carrier waves.
In R11, further enhance CA, support that many TA (Time Advance) scene and different up-downgoing are joined
Than the carrier aggregation between TDD under scene (Time Division Duplexing) community.R12 enters one
Step strengthens to be supported between FDD (Frequency Division Duplexing) and TDD different systems community
Carrier aggregation.In R12, introduce concept and the network of dual link DC (Dual Connectivity) simultaneously
Framework.Purpose is to further enhance small-cell covering scene lower network performance and speed.
In the framework of DC, two eNB provide Radio Resource for UE simultaneously, are wherein connected with MME
For MeNB, another is SeNB.Can be serviced for UE by multiple communities inside two eNB simultaneously,
I.e. CA configuration mode.The community having PUCCH channel inside MeNB is referred to as Pcell, inside SeNB
The community having PUCCH channel is Pscell.
MDT (Minimization of Drive Test) is that one utilizes business terminal collection drive test data to carry out
The ways and means of the network optimization.Such as according to signal quality and the position letter thereof of certain path measurements community
For the network optimization, such as, there is some event in breath and temporal information report network side, such as handoff failure,
Radio Link Failure, RRC connection establishment unsuccessfully etc., time record cell signal quality at that time, positional information
With temporal information report network side for the network optimization and positioning problems etc..
In CA, only detect the Radio Link Failure of Pcell, DC also simply detects Pcell and Pscell
Radio Link Failure, but the link failure of Pscell simply records Fail Type, signal quality measured etc.,
Do not trigger RRC connection reconstruction.For the measurement data in Radio Link Failure moment of Pscell for net
Network travelling performance optimization and network problem location have definite meaning, it is therefore necessary to PSCell wireless link
Failure scene is as a scene of MDT, and corresponding measurement data is as the input data of the network optimization.
In prior art, not the Radio Link Failure of Pscell as the scene of MDT, the most not
It is defined and the measurement data in this moment is reported the network backend TCE (Trace that MDT data is collected
Collection Entity), so lost network optimization data.
Summary of the invention
For the problems referred to above, the present invention proposes a kind of method that network mobility optimizes, including: UE is at Pscell
When occurring Radio Link Failure or SCG to change unsuccessfully, measure and record Fail Type, Serving cell and
The Pcell community letter of adjacent cell signal quality, positional information, timestamp information, cell information and MeNB
Breath, then reports network side, the input data optimized for network side.
Further, described Fail Type includes: T313 time-out, random access failure, RLC reach
Big number of retransmissions and SCG change unsuccessfully.
Further, described Serving cell and adjacent cell signal quality include Reference Signal Received Power RSRP
With Reference Signal Received Quality RSRQ.
