Fig. 2 is the method flow diagram of adjusting community configured information for mobile communication network of the present invention.As shown in Figure 2, the method for adjustment of community configured information of the present invention comprises following steps:
Step 1: the network equipment control portable terminal of mobile communication network starts the collecting function of subzone network coverage information.
The collecting function that the network controls portable terminal of mobile communication network starts the subzone network coverage information can be accomplished in several ways.
For example, in the terminal of gsm communication system and the location area updating rules between network side, portable terminal can be initiated location area updating request (Location Update Request) when situations such as start, lane place change or lane place periodicity timer expiry take place.The MSC equipment of network side receives can be responded location area updating after the request of terminal and the checking and accept message (Location Update Accept).MSC accepts the information gathering field of increasing network coverage in the message at location area updating, this field can be arranged in location area updating and accept after the Equivalent PLMNs field of message, length is 1 byte, is used for the collecting function that indicating mobile terminal is opened the subzone network coverage information.When the location area updating of replying as MSC is accepted network coverage information in the message and is collected field value and equal 1, the real-time collecting function of mobile terminal activating subzone network coverage information.
Above-mentioned subzone network coverage information comprises sub-district descriptor and metrical information, as subdistrict frequency point ARFCN, NCC, the BCC among the GSM, and measured value pilot frequency intensity RXLEV, incoming level, frame error rate, RXQUAL; Cell scrambling group among TD-SCDMA and the WCDMA, main scrambler and ARFCN information, Active Set and Neighbor Set information, information such as the Ec/N0 of measurement and RSCP.
Equally, also can accept the subzone network coverage information collecting function that message is opened portable terminal for TD-SCDMA and WCDMA by location area updating.
In addition, except passing through the location area updating rules, MSC also can start the subzone network coverage information collecting function of portable terminal by other message that is sent to portable terminal, for example by forms such as Cell Broadcast CBs.But adopt the location updating procedure MSC can be by the positional information of the portable terminal that comprises in the location area updating request, needs are carried out the zone and the portable terminal of the collection of subzone network coverage information and select, with energy consumption and other communication resources that reduce unnecessary communication traffic and portable terminal.
Step 2: the portable terminal that has started subzone network coverage information collecting function begins to collect the subzone network coverage information.
Portable terminal receives after location area updating that MSC sends accepts message, the network coverage information that comprises in this message is collected field judge, if this field equals 1, then begins to collect the subzone network coverage information.
Step 3: when the portable terminal that has started subzone network coverage information collecting function will take place when network abnormal conditions such as sub-district gravity treatment failure or Radio Link Failure take place unusually and portable terminal successfully be stationed (clamp) subzone network coverage information behind the sub-district again and be kept in the memory.
In mobile communication system, portable terminal can be in multiple running status.For example, in gsm communication system, the running status of portable terminal can be divided into IDLE (free time) attitude and DEDICATE (special use) attitude.
Mobile terminal-opening is stationed suitable cell after looking for net, and after normally finishing registration process, enters the IDLE attitude.After portable terminal successfully was stationed the sub-district, it will begin to do homework for cell reselection process.Portable terminal can be measured adjacent sub-district in the IDLE attitude, and the parameter of measurement is to obtain by the adjacent sub-district BA tabulation among the system message SI2 of current service cell broadcasting.Portable terminal is 6 the strongest information of adjacent cells of signal of monitoring and measuring simultaneously.When the path loss C1 of Serving cell value＜0, and the duration surpass 5 seconds, perhaps the C2 value of adjacent sub-district reaches certain value above Serving cell C2 value, and after the certain time, cell reselection process can take place.After the sub-district gravity treatment took place, terminal attempted being stationed the sub-district in these adjacent cell lists, is not the suitable sub-district of being stationed if find these sub-districts, and the time of attempting surpassed 10 seconds, the gravity treatment failure promptly takes place.
When the gravity treatment failure takes place when, the subzone network coverage information when the up-to-date subzone network coverage information recorded and stored that portable terminal will be collected is failed as gravity treatment in memory.
Gravity treatment failure back portable terminal will carry out cell selecting, after portable terminal is stationed suitable cell again, preserve the subzone network coverage information of successfully being stationed behind the sub-district.
Equally, when portable terminal is in DEDICATE attitude or CONNECTED (connection) attitude, if measuring on Radio Link, portable terminal can't be correctly decoded link data information after moving to certain zone, Radio Link Failure promptly takes place, and the subzone network coverage information of the up-to-date subzone network coverage information that portable terminal is collected before with Radio Link Failure during as Radio Link Failure is saved in the memory.
After Radio Link Failure takes place, portable terminal will carry out the sub-district gravity treatment; If cell selecting is then carried out in the gravity treatment failure; Gravity treatment success or cell selecting success back portable terminal are stationed in the proper cell.At this moment, portable terminal is preserved the subzone network coverage information of successfully being stationed behind the sub-district.
Step 4: when sending follow-up location district updating message, whether portable terminal belongs to the current sub-district of being stationed to the subzone network coverage information of being preserved is judged, after the subzone network coverage information that will belong to current area appends to location area updating message, send to the MSC equipment of cordless communication network.
After successfully being stationed the sub-district, portable terminal needs to send the location area updating request to MSC, in this location area updating request, can comprise one or more subzone network coverage information fields, this field comprises: the network coverage information type, the subzone network coverage information when the subzone network coverage information when being used for identifying this subzone network coverage information and being the gravity treatment failure, Radio Link Failure or successfully be stationed the sub-district after subzone network coverage information any; Sub-district descriptor and metrical information are used for depositing ARFCN, NCC, BCC equivalence according to specific order.
Step 5:MSC handles the subzone network coverage information of collecting, and analyzes and adjust the community configured information of respective base station.
Subzone network coverage information when subzone network coverage information when MSC can be to the gravity treatment of collecting failure or Radio Link Failure and successfully be stationed the sub-district after the subzone network coverage information compare and analyze, whether the community configured information such as cell reselection parameters, maximum power Control Parameter, adjacent cell list of judging this sub-district is reasonable, if the result who judges need adjust community configured information, then can come cell base station equipment is configured by the BSSMAP agreement.
Step 6: the network controls portable terminal of mobile communication network is closed the collecting function of network coverage information.
When not needing that a certain zone carried out the collection of subzone network coverage information, MSC can control the collecting function that portable terminal is closed network coverage information.For example MSC can be when receiving the location area updating request, and the network coverage information collection field of accepting in the message by the location area updating of correspondence is set to 0, makes and closes the network coverage information collecting function when portable terminal receives this message.
