In the fusion networking process of second generation mobile communication (2G) system and 3G (Third Generation) Moblie (3G) system, because at 3G system first stage of construction, it is more relatively that 3G network covers the cavity, therefore usually need terminal between 2G system and 3G system, to carry out the sub-district gravity treatment, and, along with deepening continuously that 2G system and 3G system merge, based on switching and may progressively carry out between professional and/or congested system, this will make terminal interoperability between the sub-district gravity treatment under the overlay area that 2G system and 3G system overlap etc. two is netted become more frequent.Communication quality when terminal is carried out the sub-district gravity treatment between 2G system and 3G system is the key factor that influences user's perception.
Present 2G system all is divided into its network's coverage area different lane place (LAC) with the 3G system, a plurality of sub-districts are arranged under each LAC, when terminal is carried out the sub-district gravity treatment, if place, cell-of-origin LAC is different with Target cell place LAC, be the sub-district gravity treatment that terminal is striden LAC, then terminal needs to carry out the LAC renewal in cell reselection process.
Fig. 1 is the fusion networking schematic diagram of present 2G system and 3G system.
As shown in Figure 1, regional A is a LAC under the 2G system, is designated as LAC-2G, and area B is a LAC under the 3G system, is designated as LAC-3G, and common described LAC-2G is different with described LAC-3G.Zone A and area B have the intersection zone C, after terminal enters zone C, if its work at present under the 2G system, then the LAC at this current place of terminal is LAC-2G, if its work at present under the 3G system, then the LAC at this current place of terminal is LAC-3G.
Referring to Fig. 1, when terminal moves to zone C when carrying out the sub-district gravity treatment from the supplementary set zone of zone C area B, if terminal switches to the 2G system from the 3G system, then terminal needs LAC is updated to LAC-2G by original LAC-3G in the process of sub-district gravity treatment.

Embodiment
For making purpose of the present invention, technical scheme and advantage clearer, below with reference to the accompanying drawing embodiment that develops simultaneously, the present invention is described in more detail.
The applicant is when attempting to solve terminal strides LAC between 2G system and 3G system sub-district gravity treatment, during long technical problem of sub-district gravity treatment time delay, various integrated planning schemes to 2G Internet resources and 3G network resource have been carried out theory analysis and field test, the result shows, the partial converage zone that 2G network equipment and 3G network side apparatus are overlapped or all the overlay area be planned to identical LAC and can solve the problems of the technologies described above effectively.
Fig. 3 is a networking communication system schematic diagram provided by the invention.
Referring to Fig. 3, zone 1 is the overlay area of 2G network equipment, and zone 2 is overlay areas of 3G network side apparatus, and zone 3 is the intersection in zone 1 and zone 2, and the subregion or the Zone Full in zone 3 are divided into identical LAC.
Normally, network equipment number in the 2G network is a plurality of, and the network equipment number in the 3G network also is a plurality of, therefore, the number in the coincidence zone of zone similarity 3 also is a plurality of, and the coincidence zone of each zone similarity 3 can be divided into a LAC zone.That is to say that each continuum in the overlay area that 2G network equipment and 3G network side apparatus are overlapped is planned to a LAC zone, different continuums is planned as different LAC zones.
The coverage in further, can also the 2G network equipment identical with 3G network side apparatus LAC zone is set to identical.
Be example with global mobile communication (GSM) system and TD-SCDMA system below, introduce the situation of diverse network integrated planning scheme being carried out theory analysis and field test:
Merge in the networking process at GSM and TD-SCDMA, the networking model that can adopt comprises at least " being total to MSC LAC altogether ", " MSC is not total to LAC altogether ", " MSC is total to LAC SGSN altogether altogether ", " MSC is not total to LAC altogether ", " MSC is total to the different LAC of SGSN altogether " five kinds of patterns.Wherein " MSC altogether " is meant the LAC-2G at place, same place and the networking structure of the same MSC that LAC-3G receives core net, " altogether MAC " is meant the networking structure of the different MS C that 2G and 3G network are received core net with the LAC-2G and the LAC-3G at place, same place, " LAC altogether " is meant that the same place of 2G and 3G network is set to the networking structure of identical LAC, " altogether LAC " i.e. " different LAC " is meant that 2G and the same place of 3G network are set to the networking structure of Different L AC, and " common SGSN " is meant the LAC-2G at place, same place and the networking structure that LAC-3G receives the same SGSN in core network data territory.
When being total to MSC, terminal is carried out the sub-district gravity treatment between gsm system and TD-SCDMA system, with do not compare carrying out the sub-district gravity treatment between gsm system and TD-SCDMA system during MSC altogether, reduced the flow processs such as Signalling exchange between different MS C, the sub-district gravity treatment time delay when therefore the sub-district gravity treatment time delay of MSC ratio is not total to MSC altogether is short.Under the situation of LAC altogether, terminal does not need to carry out the position when carrying out the sub-district gravity treatment between gsm system and TD-SCDMA system upgrades, and to upgrade the time that takies longer owing to carry out the position, and therefore LAC can obviously shorten sub-district gravity treatment time delay altogether.Under the situation of SGSN altogether, between gsm system and TD-SCDMA system, carry out sub-district gravity treatment under the PS business and will reduce Signalling exchange between different SGSN, compare with the situation that is not total to SGSN, also will shorten sub-district gravity treatment time delay.
Table one is to adopt the S660 of Huawei (T3G) and 2 sections of terminals of TCL U398 (spreadtrum), to the measured result contrast table of gravity treatment time delay in sub-district under the PS business of above-mentioned 5 kinds of networking models.
Table one
By table one as seen, when between gsm system and TD-SCDMA system, carrying out the sub-district gravity treatment under the PS business, the pass of sub-district gravity treatment time delay and networking model is: sub-district gravity treatment time delay according to not altogether MSC altogether LAC altogether SGSN → altogether MSC altogether LAC altogether the MSC of SGSN → altogether or not LAC altogether the MSC of SGSN → altogether altogether LAC altogether the MSC of SGSN → altogether altogether LAC altogether the order of SGSN shorten successively, conform to theory analysis.
Above-mentioned theory analysis and measured result show, the partial converage zone that 2G network equipment and 3G network side apparatus are overlapped or when all the overlay area scheme that is planned to identical LAC can solve terminal effectively stride the sub-district gravity treatment of LAC between 2G system and 3G system, ping-pong is serious, the technical problem that gravity treatment time delay in sub-district is long.In order to verify the technique effect of this scheme, the applicant has also carried out checking on the spot to this scheme in the mobile communications network of Xiamen, specifically asks for an interview the following describes:
Fig. 3 is a BSC2F1 overlay area schematic diagram in the RNC4 in the TD-SCDMA communication system and the gsm communication system in the mobile communications network of Xiamen.
As shown in Figure 3, the overlay area of RNC4 comprises TDa and TDb, and the LAC district under TDa and TDb are original is 24576; The overlay area of BSC2F 1 comprises GSMa and GSMb, and the LAC district under GSMa and GSMb are original is 24618.Wherein, regional TDb and regional GSMb overlap.
During experiment, the LAC of the overlay area of 79 base stations that the RNC4 in the TD-SCDMA communication system in the mobile communications network of Xiamen is identical with BSC2F1 overlay area in the gsm communication system is modified as the same, being about to regional TDb is modified as the same with the affiliated LAC of regional GSMb, particularly, the LAC under regional TDb and the regional GSMb is set to 24618.
Table two is that the LAC under regional TDb and the regional GSMb is modified preceding and is modified the scope contrast table in LAC zone, back and whether terminal needs to carry out the contrast table that the position is upgraded when carrying out the sub-district gravity treatment between regional TDb and regional GSMb.
Table two
By table two as seen, when the LAC district of TDb is modified to 24618, when promptly being total to LAC, the LAC zone of GSMb and TDb all is 24618, the LAC zone of TDa is 24576, when terminal is carried out the sub-district gravity treatment between TDa and TDb, need carry out the position and upgrade, but when in TDb and GSMb, carrying out the sub-district gravity treatment, do not need to carry out the position and upgrade.When the LAC district of TDb keeps 24576 when constant, during promptly different LAC, when terminal is carried out the sub-district gravity treatment between TDa and TDb, do not need and the position, Xining is upgraded, but when in TDb and GSMb, carrying out the sub-district gravity treatment, need carry out the position and upgrade.Owing to have 79 base stations in TDb and the GSMb zone, the sub-district number that comprises is very many, carrying out the sub-district gravity treatment in TDb and GSMb zone does not need the position renewal then can reduce all terminals are carried out the position renewal in cell reselection process total degree greatly, thereby reduces the average delay that terminal is carried out the sub-district gravity treatment.
Table three is statistical forms of the position updating request number of times when carrying out the sub-district gravity treatment with modification back terminal to the LAC zone modification of TDb is preceding in RNC4 overlay area and BSC2F1 overlay area.
Table three
From table three data as can be seen, when no matter being busy or the whole day data, the position updating request number of times of VLR is to compare 33.85% and 42.54% reduction is arranged respectively with different LAC in lane place 24618 and the lane place 24576.
Usually, the paging capability of terminal in the TD-SCDMA system (being called for short the TD terminal) is lower than the paging capability of (being called for short the GSM terminal) of terminal in the gsm system, therefore, when gsm system and TD-SCDMA system are carried out common LAC networking, in order to make TD terminal and GSM terminal all have enough paging capabilities to communicate, the present invention has provided the solution that TD-SCDMA system and gsm system carry out common LAC TD terminal and unbalanced technical problem of GSM paging terminal ability when merging networking.
The application reduces the paging load of TD-SCDMA system by the paging parameters in the network equipment of revising the TD-SCDMA system, thereby promotes the paging capability of TD terminal.Usually, the calling retransmission number of times of setting is not more than first predetermined value, and paging cycle is not less than second predetermined value.
Particularly, obtain the paging parameters in the network equipment of TD-SCDMA system and the relation of TD paging terminal ability by means such as emulation or actual measurements in advance, revise described paging parameters according to this relation.
The application specifically improves the paging capability of TD terminal by the parameters such as calling retransmission of revising Tpbp and RNC side.Parameters such as calling retransmission wherein comprise the code channel number of calling retransmission number of times, paging cycle (TPBP) and SCCPCH etc.Because changing covering for the TD-SCDMA network, SCCPCH code channel number purpose may produce big influence, the present invention shirks the heavy work ands choose the light in risk control, mainly be to reach the purpose that improves paging capacity by modification to calling retransmission number of times and paging cycle, specifically take measures into: adjust the paging interval of Tpbp and RNC side and retransmit parameter such as number of times, paging interval changed 4 seconds into by 3 seconds, paging is initiated number of times and is changed into 4 times by 6 times, the effect of paging load is in the then corresponding minimizing TD-SCDMA network: the paging congestion ratio is by being improved as near 0 near 2%, thereby improved the paging capability of TD terminal.
In addition, in the original T D-SCDMA network, because 2, " paging is unreachable " phenomenon of bringing of 3G ping-pong reselection is serious, the present invention is when implementing " 2,3G LAC networking altogether ", be set to-78dbm (25dB) by TD-SCDMA network side parameter S searchRAT, GSM network side reselecting parameters keeps existing network default value QsearchI=7 (always), TDD_Offset=5 (12db), the called paging success rate under investigation 2, the 3G ping-pong reselection.Test method is: called every 5s, 10s, 15s, 20s paging, and keep the calling of network connection state more than 10 seconds to be considered as the paging success to the back paging, paging is considered as paging failure to back network connection state less than 10 seconds calling.The test point field intensity is about G net-70dbm, about T net-80dbm, result of the test such as following table four:
Table four
Can see that from table the called paging success rate the ping-pong reselection state under was 100% (haveing nothing to do at interval with called paging) after rising to " common LAC networking " by 40% " different LAC networking " under.Shown employing " LAC networking altogether " scheme,, also can effectively evade " paging is unreachable " phenomenon even under worst situation.
As seen, carrying out " LAC networking altogether " is the effective ways that shorten the gravity treatment time delay, the compare networking model of " altogether MSC/LAC ", can shorten nearly 50% time delay, the time delay of unidirectional gravity treatment shortens to about 2s from 4-5s, and can promote the called paging success rate under the ping-pong reselection state.
The above is preferred embodiment of the present invention only, is not to be used to limit protection scope of the present invention, all any modifications of being made within the spirit and principles in the present invention, is equal to replacement, improvement etc., all should be included within protection scope of the present invention.
