Embodiment
The radio resource management method of multi-modulation scheme networking of the present invention, multi-standard communication network are (among the present invention; Be also referred to as the multi-modulation scheme networking) and the main thought of wireless resource management apparatus be; Interconnect through interface between each single system network, obtain wireless resource information and/or resource information in abutting connection with the single system network; Carry out coordinated management according to its place single system network and in abutting connection with the wireless resource information and/or the resource information of single system network again, thereby realize the systematized management of the resource of multi-modulation scheme networking.
As shown in Figure 1; The radio resource management method of multi-modulation scheme networking of the present invention; Realize based on the multi-modulation scheme networking; Each single system network of forming this multi-modulation scheme networking includes RRM, and (Radio Resource Management RRM) installs, and interconnects through interface between the wireless resource management apparatus of each single system network; Provide the interactive function of wireless resource information between different systems also to select suitable standard, to reach the whole system OPTIMAL ALLOCATION OF RESOURCES for the current business that inserts this standard.
This method comprises:
Step 101: the wireless resource management apparatus of single system network is obtained in abutting connection with the wireless resource information of single system network and/or resource information;
Step 102: the wireless resource management apparatus of said single system network is carried out coordinated management according to its place single system network and in abutting connection with the wireless resource information and/or the resource information of single system network.
That is, wireless resource management apparatus is responsible for being sent to other standard to wireless resource information of this standard and/or resource information, and obtains corresponding radio resource information and/or resource information from other standard; When this standard wireless system has when inserting request, the wireless resource information and/or the resource information of cumulated volume standard and other standard, decision-making optimal target sub-district in multiple standard and the system that deposits.
Link to each other through distributed framework between the wireless resource management apparatus of each single system communication network in the multi-standard communication network system; Each single system communication network wireless resource management apparatus can be a physical entity or logical block.
Pass through Co-RRM (Cooperative Radio Resource Management between the different single system communication networks; Collaborative RRM) interface (also being the interface between the inner different systems of multi-mode controller) or Iur-g interface link to each other, and link to each other with the road through Iur interface/Iu mouth between the identical standard.
As shown in Figure 2, the wireless resource management apparatus of each single system communication network links to each other through Co-RRM (Cooperative Radio Resource Management), Iur-g, Iur interface; These wireless resource management apparatus can be radio network controller (the Radio Network Controller in TD-SCDMA, the WCDMA communication network; RNC), (the Base Station Controller of the base station controller in the gsm communication communication network; BSC), the base station controller in the cdma mobile communication network (CDMA Base Station Controller, CBSC) etc.Wherein, two wireless resource management apparatus that link to each other through the Co-RRM interface belong in the same multi-mode controller network element, and the with dashed lines collimation mark is shown among the figure.
Pass through the mutual Radio Resource of corresponding interface, resource information between the different systems communication network RRM device; Wherein only can mutual wireless information on load between Iur-g or the Iur interface; The Co-RRM interface can also mutual cell attribute information, resource information etc. except can mutual wireless information on load.
The pre-configured coordinated management strategy of each wireless resource management apparatus also carries out coordinated management according to said coordinated management strategy, and said coordinated management strategy includes but not limited to following strategy:
Load balancing strategy selects the lightest single system network of load as the objective network that inserts or switch; Promptly; Take all factors into consideration each load state in abutting connection with the single system network, service access or be redirected in the lightest system of load, thereby realize the maximization of wireless resource utility efficiency; Farthest utilize the Radio Resource of multi-standard communication network, and then improve the trunking capacity of multi-modulation scheme overlay area; Realize the switching between each single system network in the multi-mode networks, avoid only considering the frequent switching that the factor of single standard communication network causes, farthest improve user experience.
Or load-threshold strategy, current single system offered load surpass when presetting thresholding, and specific transactions is cut toward specific different standard network;
Or; The Target cell selection strategy; Load is the lightest or sub-district that signal quality is best as loading according to each signal quality in abutting connection with the standard network, no specific electric load, transmission, is confirmed the Target cell of different standard system signal optimal quality as the Target cell that inserts or switch.
For fear of pre-configured each the preferential loaded service of standard system of the conflict of corresponding strategies between different systems, specifically according to the demand customization of operator, like the professional preferential 2G system of CS, the PS business is the 3G system preferentially; Before certain business carried out coordinated management, said wireless resource management apparatus was confirmed type of service according to this professional service request parameter earlier; Wireless resource management apparatus is carried out coordinated management according to present type of service and the preferential loaded service of each standard.
