In the such scheme, exist in same geographic area under the situation of many wireless networks, because bad channel quality or other reason are can not in time obtain service request the time, former Serving cell is used at the Radio Resource of other good network of same covering position channel quality and is finished service to this terminal when the terminal in the network.Network wherein to be used can be according to service request kind and terminal capability decision.
The application scenarios of the embodiment of the invention is described below in conjunction with Figure 14, Figure 15, Figure 16.
Should be with in the scene, WCDMA is first network, LTE is the network that is superimposed upon on the former network WCDMA overlay area, i.e. second network.Can stand and two kinds of same networking modes that cover of base station coexistence altogether for the base station in the base station of two kinds of systems.Under these two kinds of networking modes, two systems cover same sector, and promptly WCDMA sub-district and LTE sub-district cover the residing same position of terminal jointly.
As shown in figure 14, the method for processing terminal service request comprises in the mixed networking system:
Perhaps, the WCDMA base station judges whether the network base station of needs switching terminal according to the load condition of WCDMA base station self, to carry out the wireless side transmission by the LTE base station.If the load of WCDMA base station self is overweight, then can't be the professional enough resources of terminal distribution of new application.
Step 143 judges whether the base station to be switched to the LTE base station, when judged result when being, execution in step 144.The step of judging specifically is decomposed into the flow process among Figure 15.
Terminal in the step 145, WCDMA network inserts the LTE base station, connects between WCDMA base station and the LTE base station simultaneously.
As shown in figure 15, step 143 may further comprise the steps:
Step 152 if terminal is not supported dual mode capability, then directly finishes.Otherwise, execution in step 153.In this enforcement, terminal need have dual mode capability, can support the LTE system, also can support the WCDMA system.
In the foregoing description, in data transmission procedure, utilize vacant LTE resource to eat dishes without rice or wine to transmit, fully take into account utilization Radio Resource.Simultaneously, terminal inserts WCDMA system core net and charges, and does not change the charging method of terminal, and charging way is fairly simple, also need not change the existing any configuration of terminal, and it still resides in the WCDMA system.
As shown in figure 16, carry out the flow graph of business data transmission by LTE base station and WCDMA base station for terminal.Transmits data packets is drawn together two aspects, is the radio open transfer of data on the one hand, i.e. the wireless side transfer of data.In the wireless side data transmission procedure, the decoding work that wireless side sends the coding of data and receives data is being responsible for as WCDMA base station and terminal data terminal in the LTE base station.
Be the transfer of data between the base station on the other hand.Interconnect between two base stations and carry out data and transmit fast, without the LTE core net.LTE system base-station and WCDMA system base-station cover same zone simultaneously, and the two can be stood or coexist altogether, and the two can be made in the machine frame if stand altogether, and coexistence can connect with optical fiber.In two base stations, add a Transmit-Receive Unit respectively, bill unit separately and receipts unit are finished packing respectively and are conciliate packet function, between the base station with a specific interface (DMA (Direct Memory Access for example, direct memory access) wired connection interface), be responsible for the transmission of the big data quantity after the packing between two base stations, realize the quick transmission of data between the base station.Because what transmit between two base stations is before the coding or decoded data, is again wire transmission, can be directly to the transmission fast of data packing back.Optionally, can carry out wireless connections between the base station.
The present invention is under the mixed networking condition, can make full use of wireless network resource, reduce presence of intercell interference and improve a kind of method of cell throughout based on the support of dual-mode terminal, can be applicable to the mixed networking system (for example mixed networking system of WCDMA, LTE OFDMA) of communication field.On the basis of the charge mode that does not change original terminal, can accomplish that to the making full use of of Radio Resource elevator system throughput and capacity improve the terminal impression.Consider from the angle of operator, in the networking stage at the initial stage of newly-built system, the number of terminals that needs to serve may be fewer, load is less, and vacant resource is many, and original overlay network may exist the unappeasable situation of the support of big data rate services, adopt such scheme not only can solve original network problem, and newly-built grid also can seamlessly transit, and do not change existing charging policy simultaneously, and charging way is simple.If two kinds of covering systems are the networks by different operator's operations, the operator of so former network only need pay the overall performance that certain expense just can be improved network, for more terminal provides favorable service.
Service request in the embodiment of the invention is not limited to the data service request, can be other service request.: network of the present invention is not limited to LTE and WCDMA, applicable to other networks.Terminal can be mobile phone etc.
