Description
Technical field
The present invention relates to the mobile communication technology field, specifically relate to a kind of method, Apparatus and system from the macrocell gravity treatment to limited network.
Background technology
Along with the development of mobile communication system, the service quality that system can provide is more and more higher.For keeping the long-term competitive advantage of 3GPP, the standard formulation work of long evolving system (LTE) is carried out.
In the LTE system, user's request is along with the development of system is more and more diversified, system equipment variation also occurred in order to adapt to this demand, and the inside coverage base station of coverage base station, enterprise-level and some other limited network equipment arise at the historic moment in the family room that receives much concern.These equipment and pairing network thereof comprise: Home eNodeB (Home NodeB/Home eNodeB), home cell (Home Cell), access point (Access Point), private network (Private Network), private cell (Private Cell), contracted user organize (CSG, and the limited network of some characteristic frequency layers Closed Subscriber Group) etc..The user that these network/cell only allow some to have the corresponding network authority is resident/insert, also require simultaneously these users can be resident in public network/insert, these networks are referred to as limited network.
The coverage of this limited network is little, quantity is bigger, coverage base station enormous amount in the family room particularly, in this case, need the user who belong to limited network effectively be managed, reduce the influence of the each side such as public network load increase that cause because of limited network simultaneously as far as possible.And be exactly to the management of user from the macrocell gravity treatment to limited network to the importance that the user who belongs to limited network effectively manages.
A kind of re-selection process scheme in UMTS is at present, when the signal quality that measures Serving cell when the user terminal (UE) that resides in Serving cell and be in idle condition is lower than certain threshold value, this UE begins to start to the measurement of the adjacent sub-district of frequency/different frequency/different system together, and adjacent cell signal is judged, thereby determine whether to carry out the sub-district gravity treatment according to the R criterion.This R criterion mainly is, when UE measured adjacent sub-district, if think that adjacent sub-district is better than Serving cell, perhaps signal quality was stronger, and then gravity treatment is to adjacent sub-district.
In realizing process of the present invention, the inventor finds, when using above-mentioned gravity treatment scheme to carry out the limited network gravity treatment, if limited network is in the position near the macrocell center, then the signal quality of the service macrocell that measures in macrocell of UE nearly all is higher than the threshold value that starts nearby region measurement, therefore UE can not start the measurement to limited network, just there is no fear of gravity treatment to limited network yet.
In addition, even the signal quality of Serving cell is lower than the threshold value that starts nearby region measurement, and UE started the measurement to limited network, can gravity treatment but UE still can not be better than Serving cell because of the signal quality of limited network to limited network.
In the above two kinds of cases, all can cause under the stronger situation of macrocell signal quality, even be positioned at the operate as normal needs that macrocell or near limited network signal quality can satisfy UE, UE also can't gravity treatment to this limited network.
In sum,, can make UE the time, under the stronger situation of macrocell signal quality, can also farthest preferential gravity treatment arrive limited network near limited network at present not at the reselecting method of limited network.

Embodiment
For making the purpose, technical solutions and advantages of the present invention clearer, various embodiments of the present invention are described in further detail below in conjunction with accompanying drawing.
The realization flow of the inventive method embodiment as shown in Figure 1, corresponding following steps:
This gravity treatment threshold value is specifically as follows the signal quality threshold value.
If what obtained is the signal quality threshold value, then this obtain manner has multiple.
Such as, can be provided with by the network side of public network and allow the signal quality threshold value of gravity treatment, and in macrocell, send this threshold value by network side to limited network; UE then can obtain this threshold value from the message that the service macrocell issues.Specifically can broadcast this threshold value in this cell range by macrocell, and can broadcast this threshold value by system message, this threshold value specifically can be arranged among the P-BCH or D-BCH of broadcast message.。And the network side of public network is specifically as follows a plurality of limited networks same threshold value is set; Also limited network can be classified, a threshold value is set at each class limited network; Can also threshold value be set respectively for each limited network.
Can also be by the network side signalization quality gate limit value of limited network, and in the limited network community scope, send this threshold value by network side, UE then obtains this threshold value from the message that limited network issues.Equally, concrete send mode can be this threshold value of broadcasting equally, and can broadcast this threshold value by system message equally, and this threshold value specifically can be arranged among the P-BCH or D-BCH of broadcast message.Certainly, the network side of limited network also can be provided with the signal quality threshold value of other limited networks, and this threshold value is handed down to UE.Under this disposition, the corresponding same threshold value of a plurality of limited networks can be set also; Limited network can also be classified, at threshold value of each class limited network predefine; Can also be each limited network difference predefine threshold value.
Can also be limited network predefine threshold value in UE, then UE can directly obtain the signal quality threshold value among this UE.Can also make amendment to this signal quality threshold value according to the order that public network or limited network issue afterwards, perhaps make amendment by craft or other modes.And in UE, under the situation of predefine threshold value, the corresponding same threshold value of a plurality of limited networks can be set also; Limited network can also be classified, at threshold value of each class limited network predefine; Can also be each limited network difference predefine threshold value.
No matter be network side setting by public network, still being by the network side setting of limited network, still is predefine signal quality threshold value in UE, and this threshold value can be determined by operator, also can be provided with, can certainly formulate jointly by operator and webmaster by webmaster.For by the network side setting of limited network and in UE predefine threshold value both of these case, this threshold value can also be determined according to the characteristic of limited network by the user.
In addition, when concrete signalization quality gate limit value, can be provided with according to information such as limited network community transmitting power and coverages, such as, set threshold value will guarantee the transmitting power of limited network and/or the normal use needs that coverage can satisfy UE.
The difference of this step and prior art is that prior art is when the signal quality of macrocell is lower than certain thresholding, just starts the measurement to limited network community; And this step 102 does not need to carry out this processing, can directly start.
When specific implementation, the meaningless measurement of being done when avoiding UE not have limited network nearby, UE can also determine whether by the corresponding relation of macrocell and adjacent limited network community to exist and the adjacent limited network of service macrocell, and after determining there is adjacent limited network, determine that this adjacent limited network is a limited network to be measured, and start measurement determined limited network.
For the LTE system, it has replaced LA in the UMTS system with TA, at this situation, do meaningless measurement when avoiding UE not have limited network nearby, then can in terminal, write down the sign of the TA at the macrocell place adjacent with the limited network community that allows to insert, when in terminal is determined the information of self record, having comprised the sign of service macrocell place TA, then can determine current need the measurement, and the limited network community around the service macrocell is measured limited network.
The signal quality threshold value of obtaining in the signal quality of the limited network community that step 103, basis measure and the step 101, whether gravity treatment is to this limited network to determine UE.
Specifically, if what obtained is the signal quality threshold value, then step 103 is: whether the signal quality of judging the limited network community that measures is greater than the signal quality threshold value of being obtained, if determine that then this UE gravity treatment is to this limited network.
In addition, if measure the limited network that a plurality of these UE of permission insert in the step 103, then can compare a plurality of limited network community measurement results, gravity treatment is to optimum subdistrict.Can certainly carry out gravity treatment by other selection modes according to the situation of these limited networks.
By above-mentioned handling process, can guarantee that UE arrives limited network according to the gravity treatment to the full extent of signal quality threshold value, and whether gravity treatment depends primarily on the situation of limited network to this UE, and can can't gravity treatment not arrive limited network because the macrocell signal quality of serving is good.
And UE preferably arrives limited network community, has also alleviated the load of public network, and the user is enjoyed in limited network community as far as possible initiate professional charging preferential.
In addition, above-mentioned steps 101 and 102 order there is no strict restriction, promptly can first execution in step 101, also can first execution in step 102, and can also carry out this two steps simultaneously.
Other method embodiment of the present invention judges according to the deviant between limited network and the adjacent macro cell (Qoffset).
Specifically, the signal gravity treatment threshold value of being obtained in the above-mentioned steps 101 is specifically as follows the deviant (Qoffset) between limited network and the adjacent macro cell.In this case, because the quantity of limited network is bigger usually, and the quantity of macrocell is less, so preferable implementation is that network side by limited network is provided with the Qoffset between this limited network community and the adjacent macro cell, and issues this Qoffset.Similar with aforementioned signal quality threshold value, this Qoffset also can be provided with and record in UE, and this Qoffset value can also be made amendment according to the information that limited network issues, and can certainly otherwise make amendment.
Specifically being provided with of this Qoffset is same similar with the signal quality threshold value, can be determined by operator, also can be by the webmaster setting, and can also be definite according to the characteristic of limited network by the user.
In this method embodiment, except needs are carried out above-mentioned steps 102, promptly in macrocell, start measurement to limited network community, obtain outside the signal quality information of limited network community, also need to carry out measurement to the macrocell signal quality.
Correspondingly, in the above-mentioned steps 103, determine according to the signal quality and the gravity treatment threshold value of the limited network community that measures whether gravity treatment specifically also needs to judge according to the signal quality of macrocell to limited network UE.In this embodiment, the operation that above-mentioned steps 103 needs to carry out is specially: with signal quality, the signal quality of service macrocell and the Qoffset that is obtained of the limited network community that measures, whether gravity treatment is to this limited network to judge UE according to the R criterion.Specifically can be to calculate Rn according to the signal quality of limited network and Qoffset, i.e. Rn=Qmeasure, n-Qoffset calculates Rs according to the signal quality of macrocell, i.e. Rs=Qmeasure, if s+Qhyst is Rn＞Rs then carry out gravity treatment.
In addition, embodiment is similar with first method, the above-mentioned signal quality that obtains limited network community and service macrocell, and obtain Qoffset value and there is no special sequencing and limit.
By above-mentioned processing, can guarantee that UE arrives limited network according to the gravity treatment to the full extent of the Qoffset between limited network and macrocell, and whether gravity treatment depends primarily on the situation of limited network to this UE, and can can't gravity treatment not arrive limited network because the macrocell signal quality of serving is good.
