Description
Technical field
The present invention relates to the interdepartmental unified test metering method of a kind of multimode terminal.
Background technology
In the 3-G (Generation Three mobile communication system) standard, the information of adjacent cells of the required acquisition of terminal issues from network side at present.For WCDMA and TD-SCDMA network, terminal finish the sub-district resident after, utilize the neighboring BS information of indication in the system information block (SIB11, SIB12) receive, go adjacent sub-district is measured, according to the strategy of network settings, finish cell selecting.For the terminal that is in connected state, also can come adjacent sub-district is measured according to the neighboring BS information in the measurement control messages that receives (MEASUREMENT CONTROL), provide reference information for switching to adjacent sub-district.
The adjacent sub-district of WCDMA and TD-SCDMA is divided three classes: together frequently with the adjacent sub-district (Intra-frequency neighbor cell) of access technology; Alien frequencies is with the adjacent sub-district (Inter-frequencyneighbor cell) of access technology; The adjacent sub-district (Inter-RAT neighbor cell) of different radio interface access technology.In the middle of network operation, network is by broadcast system message or send the information that the measurement control messages is notified the adjacent sub-district of terminal, as frequency, cell ID and cell scrambling etc., inform the measurement of going to carry out adjacent sub-district in the terminal of this sub-district, when satisfying the sub-district reselection conditions, resident again or be linked into new sub-district.At present in the Inter-RAT of WCDMA and TD-SCDMA neighbor cell information of adjacent cells; has only the information of adjacent cells setting of GSM and IS2000 (being cdma2000); but there is not LTE; the cell information of UMB and WiMAX system; this will be to later support LTE and TD-SCDMA/WCDMA; UMB and TD-SCDMA/WCDMA; bimodulus such as WiMAX and TD-SCDMA/WCDMA or multi mode terminal bring difficulty when carrying out the sub-district network selection; resident or insert when terminal in TD-SCDMA or WCDMA sub-district following time; just can't know and measure adjacent LTE; the sub-district of UMB or WiMAX; at LTE; when UMB or WiMAX cell signal are better than with regional TD-SCDMA or WCDMA signal, also can't be resident fast or switch to LTE; UMB or WiMAX sub-district.
Being in the third generation mobile system of representative with WCDMA and TD-SCDMA,, different system information tissues is become 18 system information blocks (SIB) according to the feature and the type of system information parameters.Also have 1 Master Information Block (MIB) and 2 schedule information pieces (SB1, SB2) in addition, comprise reference and schedule information, also carried the PLMN type information that current area is supported in the Master Information Block other system block of information.Main SIB1～7 and SIB11, the SIB12 of using in the TD-SCDMA system.
The situation of cdma20001x network is similar.Behind the terminal success access network, can measure adjacent sub-district according to the Neighboring Cell List message that receives, and finish cell selecting according to the cell selecting criterion of network settings.Be in the terminal of connection status, also can monitor Neighboring Cell List message, adjacent sub-district is measured, to select the better service sub-district.The connection status lower network also can send candidate frequency search (CFS) request and control information by Traffic Channel in addition, makes terminal search for other Candidate Frequencies.

For HRPD network (being cdma20001x EV-DO network), behind the terminal success access network, according to the adjacent area list information that receives in the Sector Parameter Message (SectorParameters), to measuring and report in adjacent sub-district, and, finish cell selecting according to the measurement of network settings.Equally, be in the terminal of connection status, also can the measurement of adjacent sub-district be reported, to select the better service sub-district according to the Neighboring Cell List message in the R.U.P.
Support in the HRPD technology with switching with the access technology adjacent area frequently, switch with the access technology adjacent area with alien frequencies, and with the switching of cdma20001x network.In network operation, network is notified to terminal by control channel with information of adjacent cells, and as adjacent area scrambler, frequency range classification, frequency etc., terminal is according to the adjacent cell signal of these information measurements, reporting measurement result, when satisfying the sub-district reselection conditions, be linked into new sub-district.Present HRPD technology is not supported the switching with access technologies such as LTE, UMB, WiMAX, this will bring difficulty when the network selection of sub-district to the following dual-mode handset of supporting LTE and HRPD, UMB and HRPD, WiMAX and HRPD, resident or insert when terminal in HRPD sub-district following time, just can't know the cell information of adjacent LTE, UMB or WiMAX, when the HRPD cell signal is worse than the LTE, the UMB that cover with the region or WiMAX sub-district, can't be resident fast and switch to LTE, UMB or WiMAX sub-district, have a strong impact on professional use and user impression.
3GPP Long Term Evolution (Long Term Evolution is hereinafter to be referred as LTE) project is the new technology development project of the maximum that starts of 3GPP over the past two years, and this is that the technology of core can be counted as " accurate 4G " technology with OFDM/FDMA.3GPP LTE can provide the peak rate of descending 100Mbps, up 50Mbps in the 20MHz spectral bandwidth; Can improve the performance of Cell Edge User; Improve cell capacity; Reduce system delay; Support the sub-district of 100Km radius to cover; Can provide the two-forty access service for 350Km/h high-speed mobile user; Support paired or non-paired frequency spectrum, but and flexible configuration 1.25MHz to the 20MHz various bandwidth.
WiMAX (Worldwide Interoperability for Microwave Access, be that worldwide interoperability for microwave inserts) be also referred to as 802.16, be an emerging wireless access wide band technology, can provide towards the high speed of the Internet to connect that data transmission distance can reach 50km farthest.Use to adapt to all kinds of wideband multimedias in order to improve frequency spectrum resource utilization rate, WiMAX has adopted a large amount of new technologies (as OFDM/OFDMA, MIMO, adaptive coding and modulating etc.).WiMAX simultaneously also is the technical system of the following public wireless broadband data network that proposes of camp, a kind of the Internet, is representing the broadband of future broadband wireless communication systems and intelligent characteristic to have advantages such as QoS guarantees, transmission rate height, business be rich and varied.
UMB is the evolution upgraded version of CDMA2000 series standard, and scalable bandwidth to 20MHz can be disposed in existing or newly assigned frequency range.The UMB system is based on OFDMA (OFDM access) technology, specially at the mobile wireless wide-band system of wireless mobile environment with real-time optimizing application, it has inherited the adaptive coding and modulating of HRPD system, HARQ (physical layer is mixed re-transmission) and QoS controlling mechanism, combine CDMA, TDM, QOFDMA (accurate OFDMA), LDPC technology such as (low density parity check codes), introduced simultaneously based on MIMO (multichannel input and output), SDMA (space division multiplexing access) and Beamforming multi-antenna technologies such as (wave beam inborn nature) make system support all kinds of application with qos requirement cost-effectively in the high-transmission efficient reaching more.
These the three kinds technology that high data rate more is provided need to consider the coordinated development of existing network in moving towards the process of using in market gradually.Common initial stage in networking, the network coverage is perfect inadequately, leak is more, need provide the seamless and continuous network coverage for the user by the existing commercial mobile network who extensively covers especially, need to support common cooperation of multimode terminal of multiple wireless access technology to satisfy such demand simultaneously.So just need network side to possess corresponding mechanism, support that multimode terminal is seamless in the network of different access technologies to move and finish business.
