Embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present invention is described.
When multimode UE start selects the sub-district resident, in available network list,, select a best sub-district of signal to carry out resident according to the minimum standard of basic service rate.
When UE initiates service request, business according to request, selecting in available network list to provide this business and the minimum network of rate, selectively initiate the sub-district gravity treatment again by UE, resident to this sub-district, send service request then, guarantee under the situation that signal allows, to satisfy the service request of UE.
As shown in Figure 2, when multimode UE starts shooting, need finish by following process and select the sub-district resident functions:
1) searches for network available in current overlay area;
2) the basic service rate of each available network of comparison;
3) select the wherein minimum network of rate;
4) judge the best sub-district of signal in the selected network, it is resident to select this sub-district to carry out;
5) registration location district information;
6) UE enters idle condition.
Above-mentioned flow process is all adopted in the same cell selecting/gravity treatment of UE under idle condition.
As shown in Figure 3, after UE is under the idle condition, initiates service request, need finish following process:
1) judges that can current area provide this business;
2) if this business can not be provided, carry out the sub-district gravity treatment, then search can provide this professional sub-district;
If search, then initiate the sub-district gravity treatment, it is resident to select wherein the best sub-district of signal to carry out in the minimum optional sub-district of rate, and goes to 4);
If do not search, then illustrating does not have in the current area of coverage such professional sub-district can be provided, and goes to 5);
3), judge that then whether current area is for providing this service tariff minimum sub-district in the current area of coverage if this business can be provided;
If, do not carry out the sub-district gravity treatment, go to 4);
If not, the sub-district of the network type that the search rate are lower.If search, then initiate the sub-district gravity treatment, it is resident to select wherein the best sub-district of signal to carry out, and goes to 4); If do not search, send request in current area, go to 4);
4) initiate service request to network, set up professional the connection with network, professional initiation process finishes.
5) return service fail, process finishes.
