Specific embodiment

The system architecture that the method that the terminal of the embodiment of the present invention switches between base station is applied simply is situated between first Continue, referring to Fig. 1, Fig. 1 is the application system Organization Chart of the method that terminal of the present invention switches between base station, within the system, core Net side includes mobile management entity (Mobility Management Entity, abbreviation：MME), gateway（Serving Gate Way, referred to as：S-GW）Deng equipment, wherein, the MME is the key control node of 3GPP agreement LTE access networks, and it can To be responsible in terminal（UE）A S-GW is selected during initialization connection for the terminal.Multiple base stations（eNodeB）Can pass through above-mentioned The MME and S-GW of core net is interacted, or can also pass through inter-base station interface（X2 i.e. shown in Fig. 1 is represented between base station Interface）Communicated.

In an embodiment of the present invention, UE is in continuous movement, it is assumed that leftmost base station is source base station in Fig. 1, UE is connected under the source base station, and middle base station is target BS, and UE is in from source base station to target BS during movement （That is shown in the direction of arrow in Fig. 1）.Source base station and target BS can pass through the network equipment 11 of core-network side（That is MME/S- GW）Communicated, or, by the inter-base station interface 12 between source base station and target BS（That is X2 interface）Communicated. In actual enforcement, the communication between base station for example preferentially can be communicated using inter-base station interface 12, but do not existed between base station and connect In the case of mouthful, it is also possible to communicated by the network equipment 11 of core-network side.

It is that DRX cycle is obtained simultaneously according to the metrical information that UE is reported by source base station in UE before target BS is switched to UE is issued to, the interruption that UE is performed in DRX modes according to the DRX cycle monitors PDCCH channels.With the continuous movement of UE, Target BS must be switched to from source base station when reaching switching condition, UE will attempt whether after target BS is switched to DRX modes are enough continuing with, the method that the terminal of the embodiment of the present invention switches between base station is to illustrate in above-mentioned UE in base It is how to reduce the processing procedure with regard to DRX between UE and target BS, to reduce the consumption of terminal during switching between standing Electricity.

Embodiment one

Fig. 2 is the schematic flow sheet of the embodiment of method one that terminal of the present invention switches between base station, the terminal of the present embodiment The method switched between base station is performed by source base station, as shown in Fig. 2 the method can include：

201st, when detecting terminal and will be switched to target BS, handover request is sent to the target BS, it is described Carry in handover request for representing that the terminal supports the information of the first ability；

Wherein, it is to adopt conventional method that whether source base station detection terminal will switch over, and for example, source base station is in discovery and eventually When signal intensity between end drops to default threshold value, by indicating terminal to report itself and the signal between multiple base stations of surrounding Mass parameter（Carry base station information）, and according to the signal quality parameter of terminal to report, judge which terminal will be switched to Individual base station, determines that the base station is target BS, and obtains the information of the target BS.

Source base station to the target BS of above-mentioned determination sends handover request, carries in the handover request for representing terminal The information of the first ability is supported, to inform that the target BS terminal supports the first ability.In the present embodiment, the first described energy Power refers to the DRX abilities of extension, and the DRX abilities of the extension are being determined according to RRM algorithms described in various embodiments of the present invention The information such as terminal traffic, terminal velocity, terminal location calculate the ability of DRX cycle.Also, in the present embodiment, for table Show that terminal supports the packet of the first ability containing two kinds of meanings, a kind of is directly to represent that terminal supports the DRX abilities for extending, can be with It is ability information, another kind is that the source-information for representing terminal for example comes from certain producer, and the terminal of the manufacturer production is all supported The DRX abilities of extension, so the information for carrying the producer just implies represents that terminal supports extension DRX abilities.In the same manner, target BS When by for representing that target BS supports that the information of the first ability returns to terminal, it would however also be possible to employ two kinds of above-mentioned expression sides Formula.

202nd, after confirming that the target BS supports the first ability, send to the terminal and report instruction letter Breath, and the target BS is being received according to for representing the handover request that the terminal supports the information of the first ability to return During confirmation, to the terminal switching command is sent；

Wherein, the described mode for confirming target BS support the first ability, for example, can be that source base station is according to its own The data base of the base station ability information for recording the multiple base stations of periphery of storage, inquiry learns that target BS supports the first ability； Or, or when target BS return Handover Request Acknowledge when, determine target BS support the first ability.

It should be noted that above-mentioned transmission to terminal reports configured information and sends switching command to terminal, can be with Be send together, or separately send；

It is exemplified below：When source base station inquiry data base learns that target BS supports the first ability, source base station just can be by Configured information is reported to be sent to terminal, it can send switching to target BS in source base station to ask that this reports the transmission of configured information Before asking, or before the Handover Request Acknowledge that source base station receives target BS return etc.；When source base station receives mesh During the Handover Request Acknowledge that mark base station returns, show that target BS has been ready for the preparation for switching, then switching is sent to terminal Order.In this case, configured information and switching command is reported to be exactly separately send.

It is exemplified below again：Source base station does not inquire about the data base of itself, but the switching to be returned according to target BS please Ask confirmation determine target BS support the first ability, that in this case, source base station can only when receive target BS return Handover Request Acknowledge when, just confirm target BS support the first ability；Now source base station again to terminal send switching command and Report configured information.In this case, configured information and switching command is reported to be exactly to send together.

Certainly, even if report configured information to send together with switching command, multiple carrying mode is also had, such as will Configured information is reported to carry in the transparent vessel in switching command, or send respectively etc., these are by follow-up each enforcement Describe in detail in example.

Wherein, it is described report configured information to include for represent the target BS support the first ability information, And the target BS needs the metrical information of the terminal to report, the metrical information refers to above-mentioned for obtaining DRX The business of the metrical information in cycle, such as terminal, speed of terminal etc..Target BS after handover request is received, according to cutting Change the information for representing terminal support the first ability carried in request, it will judge whether itself equally supports first energy Power.If supported, target BS will return Handover Request Acknowledge to source base station, and source base station can according to the Handover Request Acknowledge To learn that target BS can support the first ability；Otherwise, if target BS is not supported, target BS is to source base station Switching error messages are returned, source base station can just learn that target BS is not support the first ability according to the switching error messages , then source base station will resend handover request, no longer carry the information that the expression terminal in 201 supports the first ability, Restart to perform conventional switching flow.

The switching command sent according to source base station is performed switching, i.e. company between terminal foundation and target BS by terminal Connect, the handoff procedure is, using existing mode, no longer to describe；Measurement is obtained above-mentioned measurement letter by terminal after switching is completed Cease and report to target BS.

In the method that the terminal of the present embodiment switches between base station, be by source base station by the ability information of target BS, with And target BS needs the metrical information of terminal to report to inform terminal, such terminal just can directly be surveyed after the completion of switching The acquisition of amount information and report, compared to prior art, terminal need not again be performed and is mutually distinguishable and target BS between （Primarily to whether identification both sides support the first ability）Flow process, also need not receive again target BS transmission required measurement Information, equivalent to terminal the interaction twice between target BS is reduced, then will necessarily reduce the power consumption of terminal；And And, due to reducing the interaction between equipment, data transfer is also necessarily reduced, reduce offered load.

It is simple clear for description, in following each embodiment, by taking the DRX for extending as an example, the terminal is cut between base station The method changed is illustrated.

Embodiment two
