The MIB message is the MIB message that target BS is sent in Target cell.
Notification information can be sent to terminal independently of switching command by network side, can also be loaded in switching command and be sent to terminal.When switching command carries notification information, end objectives cell can be notified to the sending method of MIB message in the support situation or Target cell of eMTC when sending switching command, thus saving signaling.
Notification information can be the instruction information from target BS of source base station forwarding.Alternatively, notification information can be generated and sent according to the instruction information from target BS to terminal by source base station.Information indicated above is used to indicate whether Target cell supports eMTC or be used to indicate the sending method of MIB message in Target cell.
It includes following methods that terminal, which receives MIB message according to notification information:
1) when notification information is for when notifying the sending method of MIB message in end objectives cell, the reception mode that terminal matches according to the sending method with notice to receive MIB message.For example, terminal receives mode using eMTC and is received when the sending method of notice is eMTC sending method.When the sending method of notice is non-eMTC sending method, terminal receives mode using non-eMTC and is received.
2) when notification information is for notifying end objectives cell to support eMTC, and terminal supports eMTC, mode is received according to eMTC and receives MIB message, it is the reception mode to match with eMTC sending method that eMTC, which receives mode,.
3) when notification information is for notifying end objectives cell to support eMTC, and terminal does not support eMTC, mode is received according to non-eMTC and receives MIB message, it is the reception mode to match with non-eMTC sending method that non-eMTC, which receives mode,.
Optionally, when terminal does not support eMTC, network side can not issue a notice information.At this point, terminal does not support eMTC, mode directly is received according to non-eMTC and receives MIB message.Certainly, if network side do not consider terminal to the support situation of eMTC, not tube terminal support eMTC all issue a notice information when, terminal knows that itself does not support eMTC, can by directly according to non-eMTC receive in a manner of receive MIB message, without considering Target cell to the support situation of eMTC.
4) when notification information is for when end objectives cell being notified not support eMTC, terminal to receive mode according to non-eMTC and receives MIB message.When terminal supports eMTC, terminal can know that Target cell does not support eMTC, therefore receive mode using non-eMTC and receive MIB message.
Wherein, non-eMTC sends the mode of MIB message, is to repeat the method for sending MIB message in a kind of system-frames multiple in one cycle, and only send MIB in a subframe in each system-frame Message.EMTC sends the mode of MIB message, is a kind of interior mode for repeating to send MIB message in more than one subframe of system-frame.In addition, can also repeat to send MIB message in symbol rank in subframe.

3), " multiple " refer to two or more."and/or" describes the incidence relation of affiliated partner, indicates may exist three kinds of relationships, for example, A and/or B, can indicate: individualism A exists simultaneously A and B, these three situations of individualism B.Character "/" typicallys represent the relationship that forward-backward correlation object is a kind of "or".
More than, the part term in the application is explained, be convenient for those skilled in the art understand that.The embodiment of the present application is described with reference to the accompanying drawing.
Referring to FIG. 1, it is a kind of schematic diagram of wireless communication system provided by the embodiments of the present application.As shown in Figure 1, the communication system includes base station 110, base station 120 and terminal 130.The cell cell1 of base station 110 is source serving cell (abbreviation source cell), serves terminal 130.When terminal 130 is moved to Target cell cell2 from source cell cell1, the service of terminal 130 needs to be switched to Target cell cell2.It should be noted that cell1 and cell2 also may belong to the same base station, only example herein.
In order to facilitate discussion, the base station where source cell is known as source base station in following embodiment in the application, as shown in figure 1 base station 110.Base station where Target cell is known as target BS, as shown in figure 1 base station 120.
Currently, network side is by increasing whether cell indicating cell supports eMTC newly in MIB message.When terminal 130 switches from source cell cell1 to Target cell cell2, the MIB message for needing first to receive Target cell cell2 just can know that whether Target cell supports eMTC, however terminal 130 is not aware that whether Target cell cell2 supports eMTC before the MIB message for not receiving Target cell cell2.If Terminal 130 repeats to receive MIB message not by the way of eMTC, then can not obtain merging gain the case where Target cell supports eMTC, under the scene of weak covering, be unfavorable for switching.If terminal 130 repeats to receive MIB message by the way of eMTC, in the case where Target cell does not support eMTC, network side does not press eMTC mode and repeats to send MIB message, is likely to result in negative gain.As it can be seen that terminal, when not knowing whether Target cell supports eMTC, if the sending method that terminal receives MIB message in the mode and Target cell of MIB message mismatches, the probability of handover failure increases, it also will increase handover delay, influence user experience.
In view of this, the embodiment of the present application provides information transferring method and device in cell switch process in order to reduce the problem of mode that terminal receives the mode of MIB message and target BS sends MIB message mismatches and leads to the increase of handover failure probability.In handoff procedure, i.e. before the MIB message of terminal reception target BS, network side notifies the eMTC of end objectives cell to support the sending method of MIB message in situation or Target cell, so that terminal receives MIB message according to corresponding mode, the mode for sending MIB message with target BS matches, to improve the probability of handover success, handover delay is reduced.
In the embodiment of the present application, the sending method of MIB message includes: eMTC sending method and non-eMTC sending method.Both modes are described below with reference to Fig. 2 and Fig. 3.
Referring to FIG. 2, it illustrates a kind of schematic diagrames of non-eMTC sending method provided by the embodiments of the present application.Here, for sending MIB message based on LTE mode.As shown in Fig. 2, in the present embodiment, non-eMTC sending method is using 40ms as a cycle, which includes 4 system-frames, 1 MIB message is sent in each system-frame, then sends 4 MIB message in a cycle.Meet in system-frame and transmit MIB message for the first time in the system-frame that System Frame Number mould 4 is 0, remaining system-frame is for repeating the MIB message of transmission transmission for the first time in same period.For example, the system-frame that System Frame Number is 0 in Fig. 2 meets the condition that mould 4 is 0, then MIB message, such as MIB1 can be transmitted for the first time in the system-frame, and 3 repetition transmission MIB1 in the system-frame 1,2 and 3 in the period where No. 0 system-frame.For another example, the system-frame that System Frame Number is 4 meets the condition that mould 4 is 0, then can transmit MIB message, such as MIB2 for the first time in the system-frame, and 3 repetition transmission MIB2 in the system-frame 5,6 and 7 in the period where No. 4 system-frames.Transmission for MIB message in other system-frames for meeting mould 4 and being 0 and where them in periods on remaining system frame the transmission of MIB message with it is described above similar, details are not described herein.
In the case where channel quality is good enough, terminal may only receive the MIB message wherein once transmitted in a cycle, it will be able to successfully solve MIB message.If channel quality is poor, terminal will The MIB message received in a cycle is successively merged, then is decoded, until successfully solving MIB message.
It should be noted that the MIB message in the same period be it is identical, the MIB message in different cycles can be different.
It is to repeat the method for sending MIB message in a kind of system-frames multiple in one cycle, and only send MIB message in each system-frame in a subframe as it can be seen that non-eMTC sends the mode of MIB message.
Referring to FIG. 3, it illustrates a kind of schematic diagrames of eMTC sending method provided by the embodiments of the present application.Here, for sending MIB message based on eMTC mode.As shown in figure 3, in the system-frame of transmission MIB message, increasing subframe relative to the non-eMTC sending method in Fig. 2 for repeating and sending MIB message.For example, in the present embodiment, MIB message is not only sent on 0 work song frame, also add 9 work song frames for repeat transmission MIB message.Further, can in 9 work song frame symbol ranks duplicate transmission MIB message.Using eMTC sending method, it is adapted to the poor environment of channel quality, bigger merging gain is obtained by more repeating, to achieve the purpose that enhancing covering.
As it can be seen that eMTC sends the mode of MIB message, it is a kind of interior mode for repeating to send MIB message in more than one subframe of system-frame.In addition, can also repeat to send MIB message in symbol rank in subframe.
It should be noted that Fig. 2 or Fig. 3 only illustrates non-eMTC sending method or eMTC sending method, with no restrictions to above-mentioned specific value, such as period length, number of repetition, duplicate frame number, subframe numbers.
Referring to FIG. 4, it is the flow chart of the information transferring method in a kind of cell switch process provided by the embodiments of the present application, method includes the following steps:
S410: source base station, which is determined, is switched to Target cell from source cell for terminal, and sends switching request message to target BS.Wherein, terminal is switched to Target cell from source cell for requesting by switching request message.
In this way, target BS can receive the switching request message of source base station transmission.
When not being directly connected between source base station and target BS, source base station can trigger equipment of the core network and send switching request message to target BS.Step S410 ' in such as figure.At this point, target BS can receive the switching request message of equipment of the core network transmission.
S420: after target BS receives switching request message, in response to the switching request message to source base station Send instruction information.
Wherein, instruction information is used to indicate whether Target cell supports eMTC or be used to indicate the sending method (eMTC sending method or non-eMTC sending method) of MIB message in Target cell.
Target BS directly can send instruction information to source base station, can also send instruction information to source base station by equipment of the core network.For example, switching request message is when sending from equipment of the core network to target BS, and instruction information can be sent to equipment of the core network by target BS, and equipment of the core network will indicate that information is transmitted to source base station when not being directly connected between source base station and target BS.Step S420 ' in such as figure.
In this way, source base station can receive the instruction information of target BS transmission.
S430: source base station notifies whether end objectives cell supports the sending method of MIB message in eMTC or Target cell according to the instruction information received.That is, notification information is sent to terminal, the sending method for notifying end objectives cell whether to support eMTC or for notifying MIB message in end objectives cell.
In this way, terminal can receive the notification information of source base station transmission, which is used to indicate whether Target cell supports eMTC or be used to indicate the sending method of MIB message in Target cell.
S440: terminal receives MIB message when receiving the switching command of source base station transmission, according to notification information.
As it can be seen that in the embodiment above, network side has just been notified of end objectives cell to the sending method of MIB message in the support situation or Target cell of eMTC in handoff procedure.So, terminal can know whether Target cell supports the sending method of MIB message in eMTC or Target cell when receiving switching command, and then MIB message is received by the way of matching, the success rate of MIB message sink is improved, to improve the success rate of switching.
It should be noted that notification information can be sent to terminal independently of switching command by network side, it can also be loaded in switching command and be sent to terminal.Notification information is loaded in switching command, it is possible to reduce the signaling in handoff procedure.In short, notification information can be loaded in switching command, it can also be transmitted in other message, or individually transmission, herein with no restrictions.
In above step S410 or S410 ', terminal is switched to Target cell from source cell to determine by the measurement report that source base station can be reported according to terminal.For example, terminal, after accessing source base station, source base station can configure measurement strategies for terminal, and terminal is measured and reported according to the configuration of source base station.Source base station receives terminal reporting measurement reports, and judgement can be switched over according to policy report, for example, can determine when the signal quality for finding Target cell is more preferable and switch the terminal into Target cell.And then switching request message or triggering equipment of the core network transmission switching request message are sent to target BS.
When being directly connected between source base station and target BS, such as when being connected by X2 interface, switching request message can be transmitted directly to target BS by source base station.When not being directly connected between source base station and target BS, source base station can trigger equipment of the core network and switching request message is sent to target BS.This will be described in detail in subsequent embodiment.
Optionally, whether switching request message carried terminal supports the information of eMTC.The ability information of oneself can be reported to source base station by terminal, and whether which can support the information of eMTC with carried terminal.Whether source base station further can support the information of eMTC by carried terminal in switching request message, to notify target BS terminal to the support situation of eMTC, or whether terminal can be supported the information of eMTC to be sent to equipment of the core network by source base station, whether equipment of the core network carried terminal in switching request message supports the information of eMTC, to notify target BS terminal to the support situation of eMTC.In this way, target BS can just issue instruction information when terminal supports eMTC, in this way, can be with saving signaling.
Certainly, whether source base station can not also support whether terminal can not be supported the information of eMTC to be sent to equipment of the core network by the information of eMTC or source base station by carried terminal in switching request message.Whether tube terminal does not support eMTC to target BS, and sending method of the Target cell to MIB message in the support situation or Target cell of eMTC is all sent to source base station.
In above step S420 or S420 ', when target BS receives switching request message, know that source base station will switch the terminal into target BS, when target BS determines that oneself can provide service for terminal, resource is got out for terminal, and response message is sent to source base station or equipment of the core network, wherein the response message is properly termed as switching request acknowledgement message again.At this time, instruction information can be carried in the response message, inform source base station Target cell whether support eMTC perhaps in Target cell the sending method of MIB message so that whether source base station notice end objectives cell supports the sending method of MIB message in eMTC or Target cell.
When whether switching request message carried terminal supports the information of eMTC, whether target BS can support the information of eMTC according to terminal, when determining that terminal supports eMTC, generate the response message for carrying instruction information；Otherwise, the response message for not carrying instruction information is generated.Then, response message is sent to source base station or equipment of the core network；That is target BS sends instruction information, does not otherwise send instruction information when determining that terminal supports eMTC.Whether carried terminal does not support the information of eMTC in switching request message.Target BS does not consider that terminal only generates the response message for carrying instruction information to the support situation of eMTC according to Target cell to the support situation of eMTC, and is sent to source base station or equipment of the core network；I.e. target BS does not consider that terminal to the support situation of eMTC, directly transmits instruction information.When the above target BS is by indicating that information is sent to core equipment, it will indicate that information is transmitted to source base station by equipment of the core network.
Optionally, which can be 1bit cell, when its value is " 0 ", indicate that Target cell does not support that the sending method of MIB message in eMTC or Target cell is non-eMTC mode；When its value is " 1 ", indicate that Target cell supports that the sending method of MIB message in eMTC or Target cell is eMTC mode.It is of course also possible in turn, when its value is " 1 ", indicate that Target cell does not support that the sending method of MIB message in eMTC or Target cell is non-eMTC mode；When its value is " 0 ", indicate that Target cell supports that the sending method of MIB message in eMTC or Target cell is eMTC mode.Herein, be only for example, the application to instruction information form with no restrictions.
Optionally, target BS can also just send instruction information only when terminal supports eMTC and Target cell also supports eMTC.That is, target BS is only when terminal supports eMTC and Target cell also supports eMTC, just notice source base station oneself supports the sending method of MIB message in eMTC or Target cell for eMTC mode the support situation of eMTC at this point, instruction information is used to indicate Target cell.In this way, signaling can be further saved.
When being directly connected between source base station and target BS, such as when being connected by X2 interface, instruction information can be transmitted directly to source base station by target BS.When not being directly connected between source base station and target BS, target BS can will indicate that information is sent to source base station by equipment of the core network.
In above step S430, source base station is after receiving switching request acknowledgement message, it is known that Target cell is agreed to receive terminal, then sends switching command to terminal, notice terminal is switched to Target cell.At this point it is possible to carry the notification information whether notice end objectives cell supports the sending method of MIB message in eMTC or Target cell directly in switching command.In this way, terminal is when receiving switching command, it can know Target cell to the sending method of MIB message in the support situation or Target cell of eMTC, to receive the MIB message of Target cell transmission using the reception mode to match.
The above switching request acknowledgement message can be sent to source base station by target BS, can also be sent to source base station by equipment of the core network, this will be described in detail in embodiment below.
Optionally, instruction information directly can be transmitted to terminal by source base station, which is notified whether end objectives cell supports the sending method of MIB message in eMTC or Target cell as notification information.Alternatively, source base station can notify whether end objectives cell supports the sending method of MIB message in eMTC or Target cell with the notification information according to instruction Infomiation Production notification information.
Optionally, whether terminal can not supported the information of eMTC to notify to target BS by source base station in above step S420.But whether eMTC is supported to judge terminal by source base station.At this point, source base station can determine terminal support eMTC when, notice end objectives cell whether support eMTC or The sending method of MIB message in person's Target cell.For example, source base station is transmitted to terminal when determining that terminal supports eMTC, by instruction information, otherwise without forwarding.Furthermore, source base station can also further determine that Target cell to the support situation of eMTC, when determining terminal support eMTC, and determining that Target cell also supports eMTC according to instruction information, Target cell described in terminal is notified to support that the sending method of MIB message in eMTC or Target cell is eMTC mode.For example, source base station determines that Target cell supports that the sending method of MIB message in eMTC or Target cell is eMTC mode according to instruction information, further determine that terminal supports eMTC；Notification information is sent to terminal after and, notice end objectives cell supports that the sending method of MIB message in eMTC or Target cell is eMTC mode.In this way, the case where can further saving signaling, not supporting eMTC for terminal, does not give instruction, since terminal does not support eMTC, received in the way of non-eMTC, therefore, does not indicate that also there is no problem.
As it can be seen that the notification information that terminal can receive source base station transmission specifically includes following manner to know whether Target cell supports the sending method of MIB message in eMTC or Target cell:
Mode one, notification information include the instruction information from target BS of source base station forwarding, which is used to indicate the sending method whether Target cell supports MIB message in eMTC or Target cell.
Mode two, notification information are generated and sent according to the instruction information from target BS to terminal by source base station, which is used to indicate the sending method whether Target cell supports MIB message in eMTC or Target cell.
Furthermore, it is possible to trigger the transmission of information indicated above or notification information, just in the case where terminal supports eMTC with saving signaling.For example, can determine whether terminal supports eMTC by target BS, eMTC Shi Caixiang source base station is supported to issue instruction information in terminal.For another example, whether terminal supports eMTC that can also be determined by source base station, and source base station is issued a notice information in the case where terminal supports eMTC to terminal.
In above step S440, when terminal receives the switching command of network side transmission, it is known that terminal is switched to Target cell from source cell by network side.In turn, terminal will receive the MIB message of Target cell transmission, at this point, terminal can determine that the mode to match receive MIB message according to notification information.When terminal does not receive notification information from network side, such as when not including notification information in switching command, default receives MIB message according to non-eMTC mode.When terminal from network side receives notification information, terminal can receive in the following ways MIB message:
1) when notification information is for when notifying the sending method of MIB message in end objectives cell, the reception mode that terminal matches according to the sending method with notice to receive MIB message.For example, the hair of notice Send mode be eMTC sending method when, terminal using eMTC receive mode received.When the sending method of notice is non-eMTC sending method, terminal receives mode using non-eMTC and is received.
2) when notification information is for notifying end objectives cell to support eMTC, and terminal supports eMTC, mode is received according to eMTC and receives MIB message, it is the reception mode to match with eMTC sending method that eMTC, which receives mode,.
3) when notification information is for notifying end objectives cell to support eMTC, and terminal does not support eMTC, mode is received according to non-eMTC and receives MIB message, it is the reception mode to match with non-eMTC sending method that non-eMTC, which receives mode,.
Optionally, according to the description of above embodiments, when terminal does not support eMTC, network side can not issue a notice information.At this point, terminal does not support eMTC, mode directly is received according to non-eMTC and receives MIB message.Certainly, if network side do not consider terminal to the support situation of eMTC, not tube terminal support eMTC all issue a notice information when, terminal knows that itself does not support eMTC, can by directly according to non-eMTC receive in a manner of receive MIB message, without considering Target cell to the support situation of eMTC.
4) when notification information is for when end objectives cell being notified not support eMTC, terminal to receive mode according to non-eMTC and receives MIB message.When terminal supports eMTC, terminal can know that Target cell does not support eMTC, therefore receive mode using non-eMTC and receive MIB message.
As it can be seen that default receives MIB message according to non-eMTC mode when terminal does not have notified information, signaling can be so saved.When terminal has received notification information, the reception mode to match with the MIB message mode in Target cell can be used to receive MIB message according to notification information.In this way, can obtain certain merging gain when Target cell supports eMTC and terminal also supports eMTC by repeating reception MIB message, improve the success rate of switching.Can not also support eMTC in terminal, and when Target cell supports eMTC, reduce because MIB message receiving mode and sending method mismatch and caused by negative gain, improve the success rate of switching.In the above description it has been already mentioned that when source base station is connected with target BS by X2 interface, direct interaction message, the at this time switching based on X2 interface it can be known as X2 switching between source base station and target BS.When not being directly connected between source base station and target BS, but when being connected by equipment of the core network, interacting message between source base station and target BS can be realized by core net, and since the interface between base station and core net is known as S1 interface, the switching at this time based on S1 interface is known as S1 switching.Information transferring method in handoff procedure provided by the embodiments of the present application is described by taking X2 switching and S1 switching as an example separately below.
