With the increase of wireless communication frequency band and the increase of communication pattern, and with network hierarchy and isomerization Develop, the base station type in communication network is increasing, such as there is macro base station to provide large-scale covering, there is also small base stations To provide the transmission of high speed data rate.In view of operator may possess different frequency range and standard, different type of base station can Different patterns can be worked in, as macro base station works in fdd mode and small base station operation is in tdd mode.

In this multimode, multi-mode networks, it is more in multifrequency that tradition only supports that the terminal of single-frequency single mode transport cannot be satisfied The communication of efficient low delay in lay wire network.In order to improve the communication performance of terminal, the communication capacity of terminal also it is corresponding promoted with It is adapted to the transmission network of multi-frequency multi-mode.Multimode terminal can be TDD the and FDD multimode terminals for supporting different duplex modes, It can be same duplex mode but be operated in the multimode terminal of different frequency range.

When existing simultaneously multifrequency, Multi-Mode Base Station and multimode terminal in network, if still using traditional single mode transport mode The communication that base station and terminal room are carried out with agreement, then can not efficiently use the transfer resource of multi-frequency multi-mode to improve communication performance. Specifically, when for example terminal carries out data traffic transmission with small base station, a priority higher has been initiated simultaneously in network New business（Such as speech business）, a kind of traditional method is the data service for enabling small base station terminate between user, and is initiated excellent First grade higher new business.But if if the coverage area of small base station is small, and backbone network situation is undesirable, Gao You may be cannot be satisfied The transmission quality of first grade new business.For legacy communications system, if small base station cannot be satisfied certain business（Predicate sound as above Business）Performance requirement, then enable small base station by switching flow by this service switching to can meet business demand other Base station（Such as above-mentioned macro base station）, detailed process includes：Small base station obtains the new business content of user from core net first, and passes through The control plane information and user plane information of user are all transmitted to incision by the multiple handshake mechanism between small base station and base station to be cut Then base station is communicated by cutting base station with user.

However, when backbone network is undesirable between base station（As small base station and macro base station are from setting for different vendor It is standby, cause communication between devices delay very big and transmission capacity very little）, the service switching time can be caused very long with upper type, dropped Low user experience.

In addition, in the following multimode, multi-mode networks, the type of service that different base station can be supported may be further thin Change, as macro base station can support low latency, low Packet Error Ratio requirement speech business, and small base station can only support the high number of high latency According to the data service of rate, since terminal must just pre-establish the business before carrying out base station switching with current base station, this Above-mentioned switching flow can not be supported to enable speech business switch to macro base station from small base station under kind of scene, can only enable user abandon with Business transmission between small base station, then to the base station of new business can be supported to redirect and establish new connection.This process Not only delay is big, and after new business end of transmission can not fast fallback to old service resumed, cause user in difference User experience when switching between business is poor.

It can be seen that multimode terminal how to be enable rapidly to carry out accessible switching between the base stations, become this field Technical staff's technical problem urgently to be resolved hurrily.

Specific implementation mode

In order to improve the switching efficiency of multimode terminal and ensure the rollback property after switching, the present invention is based on terminals The scene of data traffic transmission is carried out with small base station, if having initiated the higher new business of priority simultaneously in network（Such as language Sound business）, from traditional switching or to redirect flow different, it is contemplated that the backbone network between base station may postpone very greatly and capacity compared with It is small, in order to reduce switching delay, for a certain base station（Cut out base station）The terminal for establishing connection, when system has new business When initiating and cutting out base station and cannot be satisfied new business demand, the present invention is directly sent the solicited message of new business by core net The base station of new business performance requirement can be supported to other（Cut base station）, new business paging is sent to establish by base station to be cut New business connects, so as to avoid enabling incision base station from being put down with the control for repeatedly interact handshaking information and user between base station is cut out Face and user plane information, to improve switching efficiency.

As shown in Figure 1, being a kind of multimode terminal switching method flow diagram proposed by the present invention, following step is specifically included Suddenly：

S101, the connection that multimode terminal receives transmitted by instruction of one or more incision base stations to be selected according to core net are built Vertical request message, one or more of incision base stations to be selected are the new hair of multimode terminal described in the support of core net selection The base station for the business of rising.

S102, the multimode terminal establish the business information selection incision base carried in request message according to the connection It stands, and instruction is kept to cutting out base station and sending, so that the base station that cuts out retains the multimode terminal currently business to be transmitted Contextual information.

S103, the multimode terminal establish RRC with the incision base station and connect and obtain incision base station configuration Transmission mode, and communicated with the incision base station according to the transmission mode.

Specifically, which enables multimode terminal be established during RRC is connect to incision base station with incision base station first The signaling for carrying configuration information is sent, configuration information includes multimode terminal and cuts out the business information between base station and cut out base station Duplex mode；

Then, multimode terminal receives the transmission mode that incision base station is sent by signaling, and transmission mode is by cutting base station root It is determined according to business information and incision base station and the duplex mode for cutting out base station.

Wherein, business information includes type of service and service priority numerical value, according to the difference that base station configures, transmission side The determination process of formula distinguishes processing according to following different situations：

（1）When the incision base station be FDD or TDD operating modes, it is described cut out base station be FDD operating modes when, if institute The service priority numerical value that base station is cut out described in the service priority numeric ratio for stating incision base station is less than preset threshold value, the biography Defeated mode be uplink corresponding with the threshold value resource distribution, the resource distribution for instruct the incision base station and Uplink is gone out with the configuration free time of fixed cycle and fixed number of sub-frames in continuous uplink subframe between the multimode terminal Transfer resource so that the multimode terminal using it is idle go out resource switch to cut out the communication operation mode between base station；

（2）When the incision base station be FDD or TDD operating modes, and it is described cut out base station be FDD operating modes when, if BTS service numerical priority value, which is cut out, described in the service priority numeric ratio of the incision base station is more than preset threshold value, the biography Defeated mode is the resource distribution of uplink corresponding with the threshold value, the resource distribution indicate the incision base station with it is described Uplink money is gone out with preassigned specific resources position and number free time in continuous uplink subframe between multimode terminal Source so that the multimode terminal using it is idle go out resource switch to the communication operation mode cut out between base station；

（3）When the incision base station be FDD or TDD operating modes, it is described cut out base station be TDD operating modes when, if institute BTS service numerical priority value is cut out described in the service priority numeric ratio for stating incision base station is more than preset threshold value, the transmission Mode is that the resource distribution of corresponding uplink, the money are matched with the threshold value and the uplink and downlink timeslot for cutting out base station Source was configured in the uplink subframe between the incision base station and the multimode terminal with fixed cycle and fixed number of sub-frames The configuration free time go out uplink transmission resource, the fixed idle subframe is at the time of cutting out corresponding to base station uplink subframe It is interior so that the multimode terminal using it is idle go out resource switch to the communication operation mode cut out between base station；

（4）When the incision base station be FDD or TDD operating modes, it is described cut out base station be TDD operating modes when, if institute BTS service numerical priority value is cut out described in the service priority numeric ratio for stating incision base station is less than preset threshold value, the transmission Mode is that the resource distribution of corresponding uplink, the money are matched with the threshold value and the uplink and downlink timeslot for cutting out base station With specified specific money in continuous uplink subframe of the source configuration instruction between the incision base station and the multimode terminal Source position and number free time go out uplink transmission resource, and the specified idle subframe is being cut out corresponding to base station uplink subframe At the time of it is interior so that the multimode terminal using it is idle go out resource switch to the communication work mould cut out between base station Formula.

It should be pointed out that in multimode terminal after being communicated with the incision base station according to the transmission mode, If multimode terminal judges to need to reconfigure, which can send transmission mode to incision base station and reconfigure finger Show, so that matching for the idle subframe after detecting that the transmission mode reconfigures instruction, is cancelled in the incision base station It sets and continues to be communicated with the multimode terminal.

The present invention by improving the communication process between multimode terminal and the base station of different mode, specific to multimode terminal with Communication process, the introducing of new signaling and the design of frame structure between base station are cut, to ensure the continuity of dual mode signal transmission And high efficiency, and terminal can be enabled fast and effectively to switch between different mode.For the technology think of that the present invention is further explained Think, in conjunction with specific application scenarios, technical scheme of the present invention is illustrated.As shown in Fig. 2, for present invention specific implementation A kind of multimode terminal switching method that example proposes, is as follows：

S201, when terminal with a certain base station（Cut out base station）When communication, if the terminal needs to send out there are one new business It rises, then can cut out base station according to type of service judgement by core net support new business to transmit.Since core net has service class Type arbitration functions to judge whether base station supports a certain business, if therefore cut out base station support new business transmission, then enable this base It stands erectly and connects service terminal；It does not support new business to transmit if cutting out base station, goes to S202；

S202, core net selection can support several base stations that new business is transmitted, and these base stations is enabled to send paging message Established and connected with terminal with request, in order to enable terminal be capable of deciding whether response new business, newly increased in the paging message with Type of service and the relevant information of priority, the signaling are denoted as S_seq.

In the step, for the instruction of service priority, the present invention proposes following two schemes：

（1）In network Paging message（S_Req i.e. described above）The inside carries service priority instruction

As it appears from the above, being existing LTE Paging IE message formats, industry is carried inside Paging message to realize The precedence information of business can increase following field：

Paging-vxxx-IEs ::= SEQUENCE {

priority INTEGER (1..?),

}

Wherein, priority is used to indicate the priority for the business for initiating calling, and terminal is quickly cut according to priority selection The pattern changed.

（2）It is notified by System Information

Symtem Information mainly indicate in Symtem Information Blocks, including SystemInformationBlockType1~SystemInformationBlockType16 etc., can by wherein certain The precedence information of a SIB instructions business, for example indicated in SystemInformationBlockType1, format is as follows It is shown：

SystemInformationBlockType1-vxx-IEs::= SEQUENCE {

priority INTEGER (1..?),

}

S203, the type of service and priority that terminal includes in the paging message according to the transmission of incision base station judge whether to connect Enter to cut base station.If judging result be "Yes", terminal to cut out base station send signaling with enable cut out base station retain it is to be transmitted Business contexts information, then goes to S204.

This step makes terminal cut out base station to enable and retain business contexts information to be transmitted to cutting out base station and send signaling. The signaling is denoted as N_seq.If judging result is "No", it is not responding to the paging information of incision base station.

During specific implementation, in order to realize that system supports terminal to cut out base station guarantor to base station transmission signaling is cut out to enable The instruction of business contexts information to be transmitted is stayed, such as lower word can be increased in existing LTE RRC connections signaling as shown above Section：

S204, terminal are established RRC with incision base station and are connect, and need to send letter to incision base station in establishing RRC connection procedures It enables and remains business contexts information to be transmitted to inform that its order cuts out base station.

New signaling is added with cutting out base station and establish in terminal in the step in the signaling that RRC is connect, with comprising its with cut out The type and priority of base station to station service cut out the duplex mode of base station, if cutting out the non-tdd mode in base station, need in signaling Middle addition cuts out time slot proportion scheme used by base station.This signaling is denoted as FB_seq.

RRCConnectionRequest message

During specific implementation, signaling is sent in order to realize terminal to incision base station to inform it and cut out industry between base station The contents such as the type and priority of business, the duplex mode for cutting out base station, can be in existing LTE RRC connection requests as shown above Increase following field in signaling：

S205 after incision base station obtains the related signaling information of terminal feedback, according to incision base station and cuts out the double of base station The transmission mode of the setting incision of the type of service of work mode and terminal base station and terminal, and corresponding transmission mode is passed through into signaling It is transferred to terminal.

Consider that terminal still maintains and cut out the communication between base station, for supporting double terminals for receiving single-shots, due to its It is only capable of carrying out uplink communication with a base station on same running time-frequency resource, between enabling it keep and switch in and out two base stations Communication, the present invention proposes the design of corresponding base station and terminal room transfer process and the design of signaling, to reach different moulds The purpose that high efficiency works together between formula base station, such as business being switched fast and retract.Specifically, mentioned by this step Transmission mode can be selected according to following several schemes：

If option A incision base station is FDD operating modes and to cut out base station be FDD operating modes, or incision base station is TDD operating modes and cut out base station be FDD operating modes, and when incision base station service priority numeric ratio cut out base station industry When numerical priority value of being engaged in is less than given value Q, the uplink transmission resource of terminal is selected to configure according to the size of Q values, without loss of generality This configuration set is denoted as ConfigTable1, and sends Resource-Allocation Result to terminal by ground.This resource distribution is that instruction is cut Enter in the continuous uplink subframe of base station and terminal room and uplink biography is gone out with the configuration free time of fixed cycle and fixed number of sub-frames Defeated resource（Namely resource does not send the information with incision inter base station communication in this section）, terminal can utilize it is idle go out resource Switch to and cut out the communication operation mode between base station.

If option b incision base station is FDD operating modes and to cut out base station be FDD operating modes, or incision base station is TDD operating modes and cut out base station be FDD operating modes, and when incision base station service priority numeric ratio cut out base station industry When numerical priority value of being engaged in is more than given value Q, the uplink transmission resource of terminal is selected to configure according to the size of Q values, without loss of generality This configuration set is denoted as ConfigTable2, and sends Resource-Allocation Result to terminal by ground.This resource distribution indicates Go out uplink in the continuous uplink subframe of incision base station and terminal room with specified specific resources position and number free time to pass Defeated resource（Namely resource does not send the information with incision inter base station communication in this section）, terminal can utilize it is idle go out resource Switch to and cut out the communication operation mode between base station.

If it is TDD operating modes that scheme C. incisions base station cuts out base station for FDD operating modes, or incision base station is TDD operating modes and cut out base station be TDD operating modes, and when incision base station service priority numeric ratio cut out base station industry When numerical priority value of being engaged in is more than given value Q, then according to the size of Q values and the uplink and downlink timeslot proportioning selection terminal for cutting out base station Uplink transmission resource configures, and without loss of generality, this configuration set is denoted as ConfigTable3, and Resource-Allocation Result is passed Give terminal.This resource distribution refers in the uplink subframe of incision base station and terminal room with fixed cycle and fixed subframe The configuration free time of number goes out uplink transmission resource（Namely resource does not send the information with incision inter base station communication in this section）, and And the fixed idle subframe needs of institute are interior at the time of cutting out corresponding to base station uplink subframe, terminal can be gone out using the free time Resource switch to cut out the communication operation mode between base station.

If it is TDD operating modes that scheme D. incisions base station cuts out base station for FDD operating modes, or incision base station is TDD operating modes and cut out base station be TDD operating modes, and when incision base station service priority numeric ratio cut out base station industry When numerical priority value of being engaged in is less than given value Q, then according to the size of Q values and the uplink and downlink timeslot proportioning selection terminal for cutting out base station Uplink transmission resource configures, and without loss of generality, this configuration set is denoted as ConfigTable4, and Resource-Allocation Result is passed Give terminal.This resource distribution indicates in the continuous uplink subframe of incision base station and terminal room with specified specific Resource location and number free time go out uplink transmission resource（Namely resource does not send the letter with incision inter base station communication in this section Breath）, and specified idle subframe needs are interior at the time of cutting out corresponding to base station uplink subframe, and terminal can utilize The resource switch that free time goes out to cut out the communication operation mode between base station.

In order to realize that incision base station sends signaling to inform that its transmission mode configures to terminal, can increase as follows IE：

DualConnectGapConfig informaion element

Wherein, periodicity=0 refers to option b and the corresponding options of scheme D in S205；Periodicity=1 refers to Option A and the corresponding options of scheme C in S205；Dual Connectgap Offset refer to the object of the idle subframe of concrete configuration Mapping position is managed, Dual Connect Interval refer to the period of concrete configuration.
