Background technology
A portable terminal of supporting multiple access technology, it had both had the 2G function, like gsm system (Globe System for Mobile Communications; Global system for mobile communications); Has the 3G function again, like UMTS system (Universal Mobile Telecommunications System, Universal Mobile Telecommunications System); It can be operated in 2G or the 3G network, obtains the network service of 2G or 3G.
When above-mentioned terminal works at the GSM single user state or use GPRS (General Packet Radio Service; When GPRS) professional; Can send measurement report, enhancing measurement report, grouping mea-sure report and divide into groups to strengthen measurement report to network according to network through the parameter in system message, grouping system message, MEASUREMENT INFORMATION (single user state) or the PACKET MEASUREMENT ORDER message such as (divide into groups free time or transmitted in packets attitudes).
The terminal is under the different working state; Quantity according to the indication of XXX_MULTIRAT_REPORTING parameter; And consider report priority, and in above-mentioned various measurement report message, the 3G sub-district of report some; Wherein XXX representes access technology, like FDD (Frequency Division Duplexing: FDD or TDD (Time Division Duplexing: time division duplex) etc.
Consider the realization of gsm system and UMTS system, be limited the opportunity that gsm system can be used for measuring the UMTS system.In packet idle state, consider the problem of mobile phone power saving, can not be used for a large amount of free time periodically to measure the UMTS system, can after paging receiving message, just can provide certain UMTS Measuring Time usually.In single user state or packet transfer state; The Measuring Time that is used for the UMTS system; Only limit to the idle frame of gsm system, and not all idle frame may be used to the measurement of UMTS system, these idle frames also will be used to decode BSIC (Base Station Identity Code: base station identity code) of contiguous GSM sub-district; Under packet transfer state, also to be used to measure work such as interference signal.Therefore the time that can be used for measuring the UMTS system is very limited.In addition; Consider obtaining of UMTS System Reports amount; Received signal code power) and signal to noise ratio Ec/N0 for the FDD system, the 2G terminal need obtain its carrier wave received power RSSI (Received Signal Strength Indicator: receive signal strength signal intensity indication), CPICH (Common Pilot Channel: (the Received Signal Code Power: of the received signal code power RSCP CPICH Common Pilot Channel); For the TDD system, the 2G terminal need obtain its PCCPCH (Primary Common Control Physical Channel: the received signal code power RSCP Primary Common Control Physical Channel).
With the TDD system is example; PCCPCH appears at the Ts0 time slot of TDD system frame structure; The periodic appearance; (Time Division-Synchronous Code Division Multiple Access: the system CDMA that the time-division is synchronous) require all base stations to keep synchronously, so the PCCPCH of all base stations will appear at (in the systematic error scope) on the same time location for TD-SCDMA; Therefore in some idle time slots constituted measurement opportunity of a idle frame that the 2G system provides and its former frame, energy measurement to 1 a TDD sub-district only.
For single user state; This measurement opportunity only the TDMA of 26 2G (Time Division Multiple Access: time division multiple access) frame could obtain once; And under the single user state measurement report cycle be i.e. 104 tdma frames of 480ms, at the measurement report of a single user state at most only arranged 4 measurement opportunitys in the cycle.These measurements might not be used for measuring the UMTS system opportunity, also will tell a part and be used for possible BSIC decoding and heavily confirm action.
For packet transfer state; The tdma frame of this measurement at least 13 2G on opportunity could obtain once; Reporting period be 480ms 2 integer power doubly, the shortlyest be 480ms, the measurement of single user state is sufficient opportunity relatively; But these measurements can not all be used to measure the UMTS system opportunity equally, and they also will be used for possible BSIC decoding and heavily confirm the measurement of action and interference signal.
So just there is a problem; Promptly in reporting period, UMTS fails the sub-district all to have surveyed, in this case; In measurement report, will use previous measurement result; Reason is, if used and currently accomplish the result of (part UMTS sub-district but not the measurement result of all sub-districts) to do by strong to weak ordering and report network, possibly miss the follow-up UMTS sub-district that measures; And the measurement result of these sub-districts may be better than the measurement result of existing sub-district, influences the decision that network is made correct switching and control terminal gravity treatment.Therefore just must use previous measurement result; For network, do not obtain new UMTS cell measurement results, and, because the space of measurement report is limited; The measurement result of the UMTS sub-district that these are repeated to report has taken the space of report, has influenced the GSM cell measurement results and has reported.
