It applies in example, base station is if it is determined that the corresponding QCI of terminal current business is 1, then base station can determine the current business of terminal
Type is symmetry classes business.
By taking VOLTE business as an example, in some specific embodiments of the present invention, base station can be with identification terminal current business
It is no to establish the special feature for having QCI=1, determine that the current type of service of terminal is VOLTE business if established, if do not built
The current type of service of vertical then determining terminal is not VOLTE business.
It can be seen that above-described embodiment, base station are capable of determining that the current type of service of terminal, Jin Erke through the invention
To select suitable communication network as terminal according to terminal present type of service.
Specifically, it is contemplated that FDD networks make FDD networks be more suitable for compared with TDD networks with the respective characteristic of TDD networks
In symmetry classes and upload class business data transmission, thus, in some embodiments of the invention, base station is if it is determined that end
It holds present type of service to be symmetry classes business or upload class business, and determines that the current communication network being resident of terminal is not
FDD networks, to make full use of the frequency spectrum of uplink and downlink, are promoted eventually then base station can indicate that the terminal is switched in FDD networks

And when determining that the communication network that terminal is currently resident is FDD networks, instruction terminal is switched to TDD networks.
Correspondingly, in some embodiments of the invention, base station is not if it is determined that terminal present type of service is symmetrical
Class business uploads class business, and determines that the current communication network being resident of terminal is TDD networks, then base station can also
It does not deal with, terminal continues to reside in current TDD networks.
In addition, it is contemplated that TDD Web vector graphic priority is relatively high in the combination network that part operator is provided at present, eventually
End often preferentially resides on TDD networks, thus, in some embodiments of the invention, if the base station determine that terminal is current
Type of service be not symmetry classes business or upload class business, base station can not execute the network being currently resident to the terminal
Determination, terminal continues to reside in former communication network.
Specifically, since in current LTE standard, FDD occupies different frequency bands from TDD respectively, and each frequency band is not by
With frequency point indicate, thus, in some embodiments of the invention, base station can be determined by cell that terminal is presently in
The communication network that terminal is currently resident.
For example, it is corresponding with FDD networks specified to be configured with several in some embodiments of the invention, on base station
Frequency point, however, it is determined that terminal initiates VOLTE business in the cell of non-designated frequency point or uploads class business, then base station can determine
Need to indicate that the terminal is switched in FDD networks, thus base station can first to the terminal configure specify frequency point measurement, etc. terminals
Switched the terminal into after report measurement results in the cell of specified frequency point, and for initiated on specified frequency point VOLTE business or
For person uploads the terminal of class business, then base station will not be dealt with, these terminals continue to reside in former cell.
In addition, in some embodiments of the invention, base station can also determine that terminal present type of service is symmetrical
Class uploads class business and determines terminal when being currently resident in TDD networks, and instruction terminal is switched to before FDD networks, right
The covering of FDD networks and/or the network load of FDD networks are checked.If detect the covering of FDD networks it is weaker (such as
Less than given threshold) or the network load of FDD networks it is larger (for example be higher than given threshold), switch the terminal into the FDD nets
The service-aware of the terminal can be caused poor after network, base station can also refuse to execute instruction the decision that terminal is switched to FDD networks.
It can be seen that in the handover scheme for the communication network that the above embodiment of the present invention is provided, base station can be according to institute
The uplink traffic and/or the corresponding QCI of the terminal current business for stating terminal current business, determine the current service class of terminal
Type, and then such industry can be more suitable for when terminal present type of service is to upload class business or symmetry classes business for terminal determination
The FDD networks of business continue business.The scheme that above-described embodiment is provided through the invention can give full play to FDD networks
When with the carrying efficiency of TDD network integration networkings, promoting the business experience of user, solve current FDD networks and TDD networks and depositing
Caused by traditional network selection technique the problems such as the decline of TDD network capacities, the network downstream wasting of resources, meet future FDD networks
With the growth requirement of TDD network integration networkings.
In addition, the handover scheme for the communication network that the above embodiment of the present invention is provided can business carry out the stage (and
Non-traffic establishment stage) the larger terminal of upstream data amount is effectively distinguished, so as to be adjusted to the logical of terminal service in time
Communication network.
In the handover scheme for the communication network that the above embodiment of the present invention is provided, base station can be in setting time
Uplink and downlink flow and QCI are counted (for example base station is that a caching is respectively created in each terminal) to judge the business of terminal
Type, and determine according to preset decision rule the type of service of terminal, to according to the type of service for the terminal determined,
According to the post-processing strategy of setting, by service bearer to FDD networks and TDD network integration networkings some network or this
On the certain frequency points of network.
The handover scheme of the communication network provided in order to illustrate the embodiments of the present invention more clearly will pass through this hair below
The handover scheme for the communication network that some bright embodiments are provided applies the process flow that base station executes in actual scene to show
Example is explained in detail.
The handover scheme of communication networks of the Fig. 3 to be provided according to some embodiments of the invention applies the base in actual scene
The schematic diagram for the process flow executed of standing.Where it is assumed that under the actual scene, FDD networks and TDD networks are simultaneously deposited and cover phase
When.
As shown in figure 3, base station is by uplink traffic that first can be according to terminal current business and/or the terminal current business
Corresponding QCI determines the current type of service of terminal.
Such as it is illustrated in fig. 3, under the actual scene, base station can be configured first according to the upstream of terminal current business
Amount and/or the corresponding QCI of the terminal current business, the type of service current to terminal are marked (301)；
Specifically, data package size, QCI transmitted in PDCP layers of set period of time of uplink and downlink due to different business etc. is real
When it is non real-time performance it is different, thus, for VOLTE business, base station can identify whether establish have QCI=1 special feature come
It identifies, if it is VOLTE business to establish base station to identify the terminal currently, is not if not establishing；For upper
Class business is passed, base station can be that each terminal creates a BUF, identify the N number of continuous PDCP numbers of plies of a period of time terminal uplink
According to the size of packet, if the size of each data packet in continuous N number of uplink PDCP layer data packets both greater than sets byte,
It is to upload class business that base station, which can mark the terminal currently,；
It, can be to base station configuration and terminal in the case where resource allows in order to make terminal obtain preferable service-aware
The corresponding switching demand of type of service, specifically such as can pair and base station configured with switching corresponding with symmetry classes business need
Ask 1, and switching demand corresponding with class business (big data upload) is uploaded 2.In turn, if the base station determine that the business of terminal
Type is symmetry classes business or uploads class business, then base station, which can be triggered, executes following procedure：If it is determined that terminal currently makes
It is TDD networks, then performs handover to the process of FDD cells；Otherwise, if it is determined that terminal it is currently used be exactly FDD nets
Network is then not processed；
Such as it is shown in Fig. 3, if the base station determine that it is not symmetry classes business to go out the current type of service of terminal, nor on
When passing class business, then base station is not dealt with, and terminal continues to reside in former communication network；If the base station determine that it is current to go out terminal
