Abstract
The invention provides a roaming control method and device. When a mobile terminal enters a roaming community, a roaming zone mobile exchange center carries out roaming control on a mobile terminal according to supplementary service information of the mobile terminal, which is obtained from an attribution home location register, and a pre-set roaming control policy corresponding to a roaming service provided by the roaming community; and the supplementary service information is used for carrying out the roaming control so that the aim of limiting the previous mobile terminal which can carry out domestic roaming to roam in the community is realized through reforming the supplementary service information of the mobile terminal which is allowed to roam in the community; and therefore, wildcard characters which are stored in the attribution HLR (Home Location Register) and are used for indicating to allow the domestic roaming are prevented from being reformed, and the technical problems of great reformation working amount and high reformation cost are solved.
Description
Technical field
The present invention relates to the communication technology, relate in particular to a kind of roam control method and device.
Background technology
In mobile communication technology, if mobile terminal can carry out National roaming, at ownership place attaching position register (Home Location Register, asterisk wildcard is set HLR), can carry out National roaming to identify above-mentioned mobile terminal, make above-mentioned mobile terminal realize roaming between each different districts.If but mobile terminal is roaming restricted movement terminal, VLR Visitor Location Register (the Visitor Location Register that allows roaming is set in HLR, VLR) list, when mobile terminal is roamed, (the Mobile Switching Center of roaming place mobile switching centre, MSC) according to roaming place VLR whether in the VLR list of the permission roaming that ownership place HLR stores, judge whether above-mentioned mobile terminal can be roamed.
in prior art, when being that specific mobile terminal is when setting up the residential quarter in isolated island or desert area, because above-mentioned residential quarter only provides service to the appointment mobile terminal, the former roaming of mobile terminal in above-mentioned residential quarter of carrying out National roaming will be restricted, be that the former mobile terminal that carries out National roaming becomes roaming restricted movement terminal, therefore, need to carry out the asterisk wildcard that National roaming becomes the limited mobile terminal of roaming to former in ownership place HLR transforms, asterisk wildcard is revised as the VLR list that allows roaming, to realize that the former mobile terminal of National roaming that carries out of restriction is in the purpose of roaming of above-mentioned residential quarter, but carry out National roaming to become the limited mobile terminal quantity of roaming huge due to former, the VLR quantity that relates in the VLR list that allows simultaneously to roam is more, cause the retrofit work amount large, improvement cost is high.
Summary of the invention
The invention provides a kind of roam control method and device, when being used for setting up the residential quarter only to the opening of appointment mobile terminal, realization is avoided being used to indicate in ownership place HLR limited former mobile terminal roaming in above-mentioned residential quarter of carrying out National roaming when the asterisk wildcard that allows National roaming is transformed, solve the retrofit work amount large, the technical problem that improvement cost is high.
An aspect of of the present present invention is to provide a kind of roam control method, comprising:
The location update request message that mobile terminal receive sends;
According to described position updating request, obtain the supplementary service information of described mobile terminal from ownership place attaching position register HLR; Described supplementary service information is used to indicate the business that described mobile terminal has been ordered;
According to roaming control strategy corresponding to services of roaming that described supplementary service information and predefined and roaming cell provide, described mobile terminal is roamed control, described roaming cell refers to the residential quarter that described mobile terminal roaming arrives.
Another aspect of the present invention is to provide a kind of roaming control device, comprising:
Receiver module is used for the location update request message that mobile terminal receive sends;
Acquisition module is used for according to described position updating request, obtains the supplementary service information of described mobile terminal from ownership place attaching position register HLR; Described supplementary service information is used to indicate the business that described mobile terminal has been ordered;
Roaming control strategy corresponding to services of roaming that provide according to described supplementary service information and predefined and roaming cell is provided control module, and described mobile terminal is roamed control, and described roaming cell refers to the residential quarter that described mobile terminal roaming arrives.
roam control method provided by the invention and device, by the supplementary service information of roaming place MSC according to the mobile terminal that obtains from ownership place HLR, and roaming control strategy corresponding to services of roaming that provide of predefined and roaming cell, described mobile terminal is roamed control, roam control owing to utilizing supplementary service information, only need the supplementary service information of the mobile terminal that can roam at roaming cell is transformed, avoided when isolated island or desert area are set up as the open residential quarter of specific mobile terminal, allow the asterisk wildcard of National roaming to transform to being used to indicate in ownership place HLR, when having solved the residential quarter only to the opening of appointment mobile terminal, the retrofit work amount is large, the technical problem that improvement cost is high.
