The present invention provides preferred implementation for step 4 in the foregoing description, and as shown in Figure 3, described step 4 comprises:
Step 41, described terminal are monitored current area and adjacent area under idle pulley, record the network signal relevant parameter;
Be example explanation terminal network selection and cell selecting process with the WCDMA network below.
After the UE start, at first should select a PLMN.Elected suffered a PLMN after, just begin to select to belong to the sub-district of this PLMN.After finding a such sub-district, from system information (broadcasting), just can know the information of adjacent area (neighboring cell), like this, UE just can select a sub-district that signal is best in all these sub-districts, residently gets off.And then, UE will initiate location registration (attach or location update).After the success, UE just resides in this sub-district and has suffered.
When UE resides in the sub-district, and after registering successfully, along with moving of UE, the signal correction parameter of current area and adjacent cells is all in continuous variation.UE will select an only sub-district, Here it is cell reselection process.
Be example explanation terminal cell reselection process with the gravity treatment of WCDMA sub-district to the flow process of GSM sub-district below.
(1) UE monitors the signal quality of current area and sub-district, adjacent area at any time under idle pulley, and the network signal quality of survey is Sx.
(2) WCDMA issues in current area system information block SIB3 in the WCDMA system message to GSM cell reselection parameters current area part, and neighbor cell just adjacent area part issues in the system information block SIB11 of adjacent area.The preferential access network attribute information of UE basis reads SIB3 and the SIB11 in the WCDMA network, obtains and described UE corresponding district reselecting parameters, and form 1 has provided the parameter that is closely related with sub-district gravity treatment strategy.
Table 1 and the closely-related parameter of sub-district gravity treatment strategy
(3) if Sx〉Sintrasearch, UE does not carry out common frequency measurement; If Sx＜Sintrasearch, UE carries out common frequency measurement.If current area does not send Sintrasearch to UE, UE carries out common frequency measurement.
(4) if Sx〉Sintersearch, UE does not carry out different-frequency measure; If Sx＜Sintersearch, UE carries out different-frequency measure.If current area does not send Sintersearch to UE, UE carries out different-frequency measure.
(5) if Sx〉SsearchRATn, UE does not carry out isosystem measurement; If Sx＜SsearchRATn, UE carries out isosystem measurement.If current area does not send SsearchRATn to UE, UE carries out isosystem measurement.
(6) Sintrasearch, Sintersearch and SsearchRATn measure thresholding accordingly, point out in " the Cell selection and re-selection info " of SIB3.Sx is the network signal quality that UE records.
(7) MS at first measures the signal correction parameter outcome record of current area in Qmeas_LEV.For existing FDD, the overlay area of TDD, GSM is arranged again, the network signal relevant parameter between the different radio access technologies can't directly compare, and need be mapped as unified standard.MS is mapped to Qmeas_LEV among the Qmap according to " mappinginfo " among the SIB3.The Qmap that current area is recorded according to said method is exactly Qmap, s.To adjacent cell Qmap, the method for measurement of n is the same.
(8) if at sub-district gravity treatment timing length (Treselection) in the time, the sub-district reselection criterion still is met, and UE just selects this sub-district, residently gets off, and reads its broadcast, and the sub-district gravity treatment finishes.
Because what the UE of different user types read can be the different districts reselecting parameters, thereby can realize operator according to the service operation strategy, allow dissimilar user's gravity treatments in specifying preferred network, thereby realize the purpose of sharing network load.The present invention realizes simply, compares with load sharing mode between other system, network quality and customer service is experienced not influence, and realize that operator is controlled fully flexibly.
