The embodiment of the present invention is suitable for several scenes, when being suitable for the concept of virtual subdistrict, when terminal is located inside a virtual subdistrict, terminal keeps wireless heterogeneous networks (Radio Resource Control usually between a prevailing transmission point or cluster head (cluster head), abbreviation RRC) link connection, when terminal carries out increase, change, transfer or the switching of link in virtual subdistrict, terminal usually requires to carry out information exchange with prevailing transmission point or cluster head.For example, terminal needs to carry out in virtual subdistrict the switching of micro-base station, at this time terminal needs and prevailing transmission point or cluster head progress information exchange, rather than macro base station；And under the scene of non-virtual cell, when terminal switches between micro-base station, terminal needs to carry out information exchange between macro base station.

Various aspects are described herein in connection with terminal and/or base station.Terminal refers to the equipment (device) for providing a user voice and/or data connectivity, including wireless terminal or catv terminal.Wireless terminal can be the handheld device with wireless connecting function or other processing equipments for being connected to radio modem, the mobile terminal communicated through wireless access network with one or more core nets.For example, wireless terminal can be mobile phone (or being " honeycomb " phone) and the computer with mobile terminal.For another example, wireless terminal be also possible to portable, pocket, hand-held, built-in computer or vehicle-mounted mobile device.For another example, wireless terminal can be a part of movement station (mobile station), access point (access point) or user equipment (user equipment, abbreviation UE).

It can be seen that, on the one hand, macro base station needs measured value and some other parameter in the measurement report sent according to terminal to decide whether to initiate link change in the prior art, some other parameter may also need terminal to be reported at this time；Some other parameter is such as the parameters such as the movement speed of terminal, carrier type and wireless access technology (the Radio Access Technology that terminal is supported for another example, abbreviation RAT) the parameters such as type, at this time, terminal reports such measured value to will cause time delay to macro base station, since the amount of the measured value of transmission is larger, therefore macro base station makes decisions according to these measured values received can then have a time delay, in turn result in the time delay of terminal links change, when terminal is more, the link change time delay of terminal is bigger.But the link change of terminal is more demanding to time delay, it is desirable to which time delay is the smaller the better, especially in multi-hop communication, more wishes that time delay reduces.

On the other hand, terminal needs measured value and above-mentioned some other measurements in reporting measurement reports Value, increases the network load of terminal side.The third aspect, macro base station is when deciding whether to change the link of terminal, also need to consider the load condition of terminal, but the load condition of terminal is constantly in variation again, therefore when terminal is sent to one load condition parameter of macro base station at this time, when judging, the load condition of terminal just may be changed macro base station again, and the situation for so then causing macro base station judgement inaccuracy occurs.

Therefore, in the embodiment of the present invention, when terminal determines at least one adjacent base station for existing at least one adjacent base station and meeting preset rules, the source base station connected to terminal sends the information for being used to indicate link change；Or when determining the target BS for existing at least one adjacent base station and meeting preset rules, the information for being used to indicate link change is sent to target BS according to the measured value of at least one adjacent base station for terminal.The information of link change is used to indicate during this by terminal initiation, on the one hand, there are a large amount of micro-base stations under a macro base station, when the problem of link switching, frequently occurs for terminal, terminal can be directly according to the measured value and some other measured value in measurement report, the moving parameter of some other measured value such as terminal, the carrier type that terminal is supported etc. parameter terminal can all be known, and the measured value in measurement report is also that terminal oneself measurement obtains, therefore terminal sends a large amount of measured value to oneself without other equipment, it can make decisions, therefore the delay problem during link switching is greatly reduced, time delay especially in multi-hop communication is reduced.On the other hand, since terminal is not necessarily to measured value being reported to macro base station, so that macro base station carries out the judgement of link switching, therefore the load of terminal is reduced, improves the business transmitting efficiency of terminal.

The embodiment of the present invention is suitable for several scenes, for example terminal switches to macro base station etc. from macro base station, is introduced by taking following scene as an example in the embodiment of the present invention:

Terminal is connected in a macro base station, while terminal needs to increase a link between micro-base station.Macro base station is source base station at this time, and micro-base station to be increased is target BS.In the concept of virtual subdistrict, source base station is main transfer point or cluster head in such cases, i.e. source base station is a micro-base station, and micro-base station to be increased is target BS.

Alternatively, terminal is connect with macro base station and micro-base station simultaneously, terminal needs to change from a micro-base station or is transferred to another micro-base station at this time, and two micro-base stations are all in the coverage area of macro base station at this time.Source base station is micro-base station at this time, and to be changed or transfer micro-base station is target BS.

Alternatively, terminal is connect with macro base station, terminal needs to switch to another macro base station at this time, and source base station is macro base station at this time, and to be switched macro base station is target BS.

In the embodiment of the present invention, macro base station is master base station, and all micro-base stations are prothetic group station (Secondary eNodeB).

In order to improve the scope of application of the embodiment of the present invention, source base station can be macro base station or micro-base station in the embodiment of the present invention, and target BS can also be macro base station or micro-base station.Preferably, source base station is macro base station or micro-base station, target BS is micro-base station.Optionally, macro base station is master base station, base station supplemented by micro-base station.

Optionally, in step 202, terminal is determined at least one adjacent base station according to the measured value of at least one adjacent base station with the presence or absence of at least one adjacent base station for meeting preset rules.Another optionally embodiment are as follows: terminal is according to the measured value of at least one adjacent base station, and the parameter of terminal itself, it determines at least one adjacent base station with the presence or absence of at least one adjacent base station for meeting preset rules, when determining at least one adjacent base station for existing at least one adjacent base station and meeting preset rules, the information for being used to indicate link change is sent to source base station.

Optionally, in the case where centralized non-virtual cell, source base station is macro base station, and target BS is micro-base station.In the case where distributed virtual cell, source base station is micro-base station, and target BS is micro-base station.

Optionally, in order to make source base station quickly determine at least one adjacent base station, and then accelerate link change efficiency, terminal sends the information for being used to indicate link change to source base station, comprising:

It includes the information for being used to indicate link change for meeting the mark of at least one adjacent base station of preset rules that terminal is sent to source base station.Or terminal sends the mark for meeting at least one adjacent base station of preset rules to source base station, and is used to indicate the information of link change.

Optionally, for source base station when determining that receiving is used to indicate the information of link change, source base station receives the information for being used to indicate link change that terminal is sent, comprising:

Source base station receives the information for being used to indicate link change of the mark at least one adjacent base station including meeting preset rules that terminal is sent.Or source base station receives the mark at least one adjacent base station for meeting preset rules that terminal is sent, and is used to indicate the information of link change.

In the embodiment of the present invention, optionally, optionally embodiment is one kind, and terminal transmission continues to work normally under source base station after being used to indicate the information of link change, until source base station triggering terminal completes link change.Another optionally embodiment mode are as follows: if the source base station that is used to indicate that terminal does not receive source base station return in preset duration receives the response message for being used to indicate the information of link change:

Terminal is measured again according to at least one adjacent base station, obtains the measured value of at least one adjacent base station；When determining at least one adjacent base station for existing at least one adjacent base station and meeting preset rules, the information for being used to indicate link change is sent to source base station according to the measured value of at least one adjacent base station for terminal.In the embodiment of the present invention, preset duration is an empirical value, such as 50 seconds, 2 minutes etc..

That is, terminal initiates the information for being used to indicate link change for the first time, if in preset duration, for example the response message for being used to indicate source base station receiving and being used to indicate the information of link change of source base station return is not received by 5 minutes, then terminal is again introduced into the process for initiating to be used to indicate the information of link change for the second time, terminal needs again to measure at least one adjacent base station for the source base station currently connected that can be listened at this time, obtains the measured value of at least one adjacent base station；When determining at least one adjacent base station for existing at least one adjacent base station and meeting preset rules, the information for being used to indicate link change is sent to source base station according to the measured value of at least one adjacent base station for terminal.

On the other hand, if terminal initiates the information for being used to indicate link change for the first time, the source base station that is used to indicate that source base station return is received in preset duration does not receive the response message for being used to indicate the information of link change, then terminal is again introduced into the process for initiating to be used to indicate the information of link change for the second time.In alternatively possible implementation, if terminal initiates the information for being used to indicate link change for the first time, the source base station that is used to indicate that source base station return is received in preset duration receives the response message for being used to indicate the information of link change, then terminal enters link change process.

Optionally, when determining at least one adjacent base station for existing at least one adjacent base station and meeting preset rules, the information for being used to indicate link change is sent to source base station also according to some parameters of terminal itself according to the measured value of at least one adjacent base station for terminal.Some parameters of terminal itself such as moving condition estimates (mobility state estimation, abbreviation MSE), the parameters such as the movement speed of terminal, the parameters such as the type of carrier type and wireless access technology (Radio Access Technology, abbreviation RAT) that terminal is supported for another example.

Optionally, the preset rules that the macro base station that terminal receives that terminal is connected is sent, the macro base station that the terminal is connected in non-virtual cell can be source base station, and in virtual subdistrict, source base station is a micro-base station.Fig. 2 b illustrates the embodiment of the present invention and provides a kind of process of linked operation method based on micro-base station Schematic diagram.As shown in Figure 2 b, in distributing cell, terminal is connect with macro base station (Macro eNB) and source base station (Source eNB).The adjacent base station of source base station is respectively adjacent base station 1 (target 1) and adjacent base station 2 (target 2).Source base station, adjacent base station 1 and adjacent base station 2 can be micro-base station, and there are the feature X that a target BS can be supported in preset rules, 1 supported feature X of adjacent base station, not supported feature X (Feature X:target1 supported, the target2 unsupported of adjacent base station 2；)；Feature X such as can be the ability connect with double-strand.This method comprises:

Step 2201, terminal receives the system information (system information) that source base station and/or macro base station are sent；It include preset rules in system information, preset rules may include that signal quality threshold and some Else Rules, Else Rule can are as follows: the feature X that target BS can be supported.It may include the information of 1 supported feature X of adjacent base station and adjacent base station 2 not supported feature X in system information；It in system information can not also include the information of 1 supported feature X of adjacent base station and adjacent base station 2 not supported feature X, but be broadcasted respectively by adjacent base station 1 and adjacent base station 2, and then be interrupted and listen to；

Step 2202: terminal periodic measures the signal of adjacent base station 1, judge whether the signal quality of adjacent base station 1 can reach switching standards (1 radio quality is good enough to support handover of measurement:target), and the signal of adjacent base station 2 is measured, judge whether the signal quality of adjacent base station 2 can reach switching standards (2 radio quality is good enough to support handover of measurement:target)；

Step 2203: considering the signal quality of source base station and adjacent base station 1, adjacent base station 2；And whether supported feature X (consider source radio quality, target1 radio quality and target2 radio quality；and support/non-support of feature X).Judged that adjacent base station 1 and the signal quality of adjacent base station 2 are all larger than signal quality threshold, and still due to 1 supported feature X of adjacent base station, and the not supported feature X of adjacent base station 2, therefore, adjacent base station 1 is determined as target BS by final terminal, that is to say, that target BS can reach switching standards；

Step 2204: terminal sends the information for being used to indicate link change to source base station, for example terminal can send the switching request (handover request for source to target 1) that adjacent base station 1 is switched to from source base station to source base station.

Optionally, there are two types of in order to preferably compatible with the prior art, in the embodiment of the present invention, terminal can have Ability, one kind are ability in the prior art, i.e. terminal measures adjacent base station, and feeds back measurement report, so that macro base station decides whether the information for initiating to be used to indicate link change.Another, terminal as in the embodiment of the present invention has the ability for the information for initiating to be used to indicate link change, that is terminal is but locally stored by measurement report no longer to macro base station reporting measurement reports, and decides whether by terminal oneself information for initiating to be used to indicate link change.

Specifically, in a kind of optionally embodiment, the ability that terminal has the information for initiating to be used to indicate link change can be preset.Another optionally embodiment are as follows: when source base station is macro base station, terminal receives the permission terminal that is used to indicate that source base station is sent and sends the instruction information for being used to indicate the information of link change；When source base station is micro-base station, terminal receives the instruction information for being used to indicate the information for allowing terminal transmission to be used to indicate link change that the macro base station that terminal is connected or source base station are sent.That is, source base station reception terminal transmission is used to indicate before the information of link change, source base station, which sends to be used to indicate to terminal, allows terminal to send the instruction information for being used to indicate the information of link change.

Specifically, the instruction information that being used to indicate allows terminal to send the information for being used to indicate link change can be sent by some system informations, such as in Master Information Block (Master Information Block, abbreviation MIB) it is sent in information, in system information block (System Information Blocks, abbreviation SIB) or dedicated RRC information.Or the instruction information for being used to indicate the information for allowing terminal transmission to be used to indicate link change is individually sent with a signaling.

Optionally, the instruction information that being used to indicate allows terminal to send the information for being used to indicate link change can also be implicit instruction information, for example, being used to indicate the instruction information for allowing terminal to send the information for being used to indicate link change is to be used to indicate the information of preset rules.Such as preset rules are that double-strand is supported to connect, source base station sends a signaling to terminal: requiring target BS that double-strand is supported to connect in preset rules.Or being used to indicate the instruction information for allowing terminal to send the information for being used to indicate link change is the information to be used to indicate the threshold value for including in preset rules.For example signal quality threshold, source base station send a signaling to terminal: requiring the signal quality of target BS in the range of the signal quality threshold in preset rules.Or being used to indicate the instruction information for allowing terminal to send the information for being used to indicate link change is for for requesting that terminal to the measurement that at least one adjacent base station measures, for example, source base station sends a signaling to terminal: it is required that terminal measures at least one adjacent base station.That is, being used to indicate the information of preset rules when terminal receives and thinking that source base station allows terminal initiation to be used to indicate the information of link change, and then terminal initially enters link change process.Alternatively, when terminal is received for making terminal think the ability for oneself having the information for initiating to be used to indicate link change to the measurement request that at least one adjacent base station measures, and then terminal initially enters link change process.

Optionally, preset rules are at least one of following:

The information for the threshold value that need to meet；The instruction information for the ability that carrier wave belonging to adjacent base station or cell have.

For example, for example preset rules are the information for the threshold value that need to meet, the information of threshold value includes the parameter area of mobile state of terminal estimation MSE, at this time, if terminal meets the requirement in preset rules, the MSE of terminal is located in the parameter area of the MSE in the preset rules.

Optionally, after the source base station transmission that terminal is connected to terminal is used to indicate the information of link change, source base station receives the information for being used to indicate link change that terminal is sent；Source base station handles the information for being used to indicate link change.

The method of Fig. 2 c and Fig. 2 d can be used for: terminal needs the case where switching from the chain road connecting with the first micro-base station or be transferred to the chain road connecting with the second micro-base station, and terminal has been connected on macro base station, it is also necessary to the case where increasing the link between a terminal and the second micro-base station.The case where terminal needs switch or are transferred on the chain road connecting with the second micro-base station from the chain road connecting with the first micro-base station Under, after terminal random access target BS, terminal needs are disconnected with source base station.

It may be seen from the foregoing that the source base station connected to terminal sends the information for being used to indicate link change when terminal determines at least one adjacent base station for existing at least one adjacent base station and meeting preset rules；Or when determining the target BS for existing at least one adjacent base station and meeting preset rules, the information for being used to indicate link change is sent to target BS according to the measured value of at least one adjacent base station for terminal.The information of link change is used to indicate in the above process by terminal initiation, so, measured value can need not be reported to source base station by terminal, but terminal oneself is determined according to measured value, and when determining the base station for existing and meeting preset rules, initiate the information for being used to indicate link change, to realize the link change between terminal and target BS, since terminal is without to source base station reporting measurement value so that the information that source base station determines whether to initiate to be used to indicate link change according to the measured value that this is reported in the program, therefore the load of terminal is reduced, improve the business transmitting efficiency of terminal.

Fig. 3 a illustrates the embodiment of the present invention and provides a kind of flow diagram of linked operation method based on micro-base station.

Based on same idea, as shown in Figure 3a, the embodiment of the present invention provides a kind of linked operation method based on micro-base station, comprising:

Step 301, terminal measures at least one adjacent base station, obtains the measured value of at least one adjacent base station；

Step 302, when determining the target BS for existing at least one adjacent base station and meeting preset rules, the information for being used to indicate link change is sent to target BS according to the measured value of at least one adjacent base station for terminal.

Optionally, the information for being used to indicate link change can be link change command.It is used to indicate after the information of link change at this point, target BS receives this, does not judge whether the process for receiving the information of use instruction link change, directly execution link change process.That is, at this point, carrying out judging whether to execute link change process by terminal.

In another optionally embodiment, the information for being used to indicate link change can request for link change.It is used to indicate after the information of link change at this point, target BS receives this, judges whether the process for receiving the information for being used to indicate link change, execute chain when receiving the information for being used to indicate link change Road changes process.That is, at this point, being judged whether to execute link change process by target BS.

Optionally, target BS is when receiving to be used to indicate the information of link change, or target BS, after receiving and being used to indicate the information of link change, target BS executes link change process when determining that receiving is used to indicate the information of link change between source base station and terminal.

Based on above-mentioned discussion, the information for being used to indicate link change is the information initiated by terminal.Optionally, the information of link change is used to indicate for making target BS when determining that receiving is used to indicate the information of link change, and link change process is executed between source base station and terminal.

Optionally, in step 302, terminal determines at least one adjacent base station according to the measured value of at least one adjacent base station with the presence or absence of at least one adjacent base station for meeting preset rules.Another optionally embodiment are as follows: terminal is according to the measured value of at least one adjacent base station, and the parameter of terminal itself, it determines at least one adjacent base station with the presence or absence of the target BS for meeting preset rules, when determining the target BS for existing at least one adjacent base station and meeting preset rules, the information for being used to indicate link change is sent to target BS.

Optionally, in order to make source base station quickly determine one adjacent base station of instruction, and then accelerate link change efficiency, terminal sends the information for being used to indicate link change to target BS, comprising:

Terminal sends the information for being used to indicate link change of the mark including source base station to target BS；Or terminal sends the mark of source base station to target BS, and is used to indicate the information of link change.

Correspondingly, target BS receives the information for being used to indicate link change that terminal is sent, comprising:

Target BS receives the information for being used to indicate link change for the mark including source base station that terminal is sent；Or target BS receives the mark for the source base station that terminal is sent, and is used to indicate the information of link change.

That is, the mark of source base station can be carried on and is used to indicate link by terminal in the embodiment of the present invention Source base station or terminal are sent in the information of change to be sent to source base station for the mark of source base station by an individual signaling or other signalings.

In the embodiment of the present invention, optionally, optionally embodiment is one kind, and terminal transmission continues to work normally under source base station after being used to indicate the information of link change, until target BS triggering terminal completes link change.Another optionally embodiment mode are as follows: if the target BS that is used to indicate that terminal does not receive target BS return in preset duration receives the response message for being used to indicate the information of link change:

Terminal is measured again according to at least one adjacent base station, obtains the measured value of at least one adjacent base station；When determining the new target BS for existing at least one adjacent base station and meeting preset rules, the information for being used to indicate link change is sent to new target BS according to the measured value of at least one adjacent base station for terminal.

Optionally, the new target BS and target BS determined by the last time can be same, can also be different.In the embodiment of the present invention, preset duration is an empirical value, such as 50 seconds, 2 minutes etc..

That is, terminal initiates the information for being used to indicate link change for the first time, if in preset duration, for example the response message for being used to indicate target BS receiving and being used to indicate the information of link change of target BS return is not received by 5 minutes, then terminal is again introduced into the process for initiating to be used to indicate the information of link change for the second time, terminal needs again to measure at least one adjacent base station for the source base station currently connected that can be listened at this time, obtains the measured value of at least one adjacent base station；When determining the new target BS for existing at least one adjacent base station and meeting preset rules, the information for being used to indicate link change is sent to new target BS according to the measured value of at least one adjacent base station for terminal.

On the other hand, if terminal initiates the information for being used to indicate link change for the first time, the target BS that is used to indicate that target BS return is received in preset duration does not receive the response message for being used to indicate the information of link change, then terminal is again introduced into the process for initiating to be used to indicate the information of link change for the second time.In alternatively possible implementation, if terminal initiates the information for being used to indicate link change for the first time, the source base station that is used to indicate that source base station return is received in preset duration receives the response message for being used to indicate the information of link change, then terminal enters link change process.

Optionally, terminal periodic measures at least one adjacent base station of the source base station currently connected in the embodiment of the present invention.Optionally, the measured value of at least one adjacent base station includes at least following one: terminal Obtained measurement result is measured at least one adjacent base station；The broadcast of at least one adjacent base station is used to indicate carrier wave belonging at least one adjacent base station or the instruction information of ability that whether cell has.Terminal measures obtained measurement result such as at least one adjacent base station are as follows: Reference Signal Received Power (Reference Signal Receiving Power, abbreviation RSRP), channel state information (: Channel State Information, abbreviation CSI) and Reference Signal Received Quality (Reference Signal Receiving Quality, abbreviation RSRQ) etc..Optionally, further include some other parameters in measured value, for example, the carrier wave supported of adjacent base station characteristic, whether parameter with wireless traffic ability etc., the continuous broadcast acquisition that such parameter passes through adjacent base station.

Since target BS is one at least one adjacent base station, optionally, what target BS received that terminal sends is used to indicate before the information of link change, the instruction information for the ability that carrier wave belonging to target BS broadcast target base station or cell have.

Optionally, when determining at least one adjacent base station for existing at least one adjacent base station and meeting preset rules, the information for being used to indicate link change is sent to source base station also according to some parameters of terminal itself according to the measured value of at least one adjacent base station for terminal.Some parameters of terminal itself such as moving condition is estimated The parameters such as the movement speed of (mobility state estimation, abbreviation MSE), terminal, the parameters such as type of carrier type and wireless access technology (Radio Access Technology, abbreviation RAT) that terminal is supported for another example.

Optionally, the preset rules macro base station that the terminal is connected in non-virtual cell that the macro base station that terminal receives that terminal is connected is sent can be source base station, and in virtual subdistrict, source base station is a micro-base station.It is discussed in detail referring to foregoing teachings and Fig. 2 b related content, details are not described herein.

Optionally, in order to preferably compatible with the prior art, terminal can have there are two types of ability in the embodiment of the present invention, one kind is ability in the prior art, i.e. terminal measures adjacent base station, and feeds back measurement report, so that macro base station decides whether the information for initiating to be used to indicate link change.Another, as ability possessed by the terminal in the embodiment of the present invention, i.e. terminal are but locally stored by measurement report no longer to macro base station reporting measurement reports, and decide whether by terminal oneself information for initiating to be used to indicate link change.

Optionally, the instruction information that being used to indicate allows terminal to send the information for being used to indicate link change can be explicit indication information, for example terminal is allowed to send the information for being used to indicate the information of link change, such as macro base station sends the signaling for the information that one allows terminal transmission to be used to indicate link change to terminal；Or It is used to indicate terminal and sends the instruction information for being used to indicate the information of link change to source base station or target BS.For example, macro base station to terminal send one require terminal to source base station send be used to indicate link change information signaling.That is, source base station not only can indicate that the ability that terminal has the information for initiating to be used to indicate link change, but also can need whom the information for being used to indicate link change is sent to for terminal designated terminal, for example be destined to source base station or target BS.Specifically, when the instruction information that being used to indicate allows terminal to send the information for being used to indicate link change is explicit indication information, macro base station can send preset rules to terminal by other signaling, perhaps terminal and macro base station appoint that preset rules or macro base station will be used to indicate the instruction information for allowing terminal to send the information for being used to indicate link change and preset rules and be sent to terminal by an information in advance.

Optionally, preset rules are at least one of following:

Optionally, the information of threshold value includes the parameter area of mobile state of terminal estimation MSE；And/or eventually The parameter area of the wireless access technology RAT at end.

Optionally, after terminal is used to indicate the information of link change to target BS transmission, target BS receives the information for being used to indicate link change that terminal is sent；Target BS handles the information for being used to indicate link change.

Optionally, terminal random access target BS；Terminal sends the mark for other micro-base stations that terminal is connected when connecting source base station to target BS, so that target BS determines the micro-base station for needing to activate from other micro-base stations.Correspondingly, what target BS reception terminal was sent is used to indicate after the information of link change, and target BS receives the mark for other micro-base stations that the terminal that terminal is sent is connected when connecting source base station；Target BS determines the micro-base station for needing to activate, and the institute that will be determined from other micro-base stations Show the micro-base station activation that needs activate.

That is, target BS reception terminal transmission is used to indicate after the information of link change, target BS receives the mark for other micro-base stations that the terminal that terminal is sent is connected when connecting source base station；Target BS determines to need the micro-base station that activates from other micro-base stations, and the micro-base station activation for needing to activate shown in determining.

For example, for example, terminal accesses macro base station, the first micro-base station, the second micro-base station and third micro-base station are also accessed at this time, and terminal this time needs to switch to the 5th micro-base station from the first micro-base station, i.e. the first micro-base station is source base station, and the 5th micro-base station is target BS.When terminal successful switch to five micro-base station, terminal is disconnected with the first micro-base station, and terminal is in the state that is not activated with the connection of the second micro-base station and third micro-base station at this time.The mark of second micro-base station and third micro-base station is sent to the 5th micro-base station by terminal, 5th micro-base station is determined oneself to need which micro-base station activated, the closer micro-base station of usual 5th micro-base station meeting active distance oneself, for example third micro-base station the 5th micro-base station of distance is closer, but the 5th micro-base station of the second micro-base station distance is distant, the 5th micro-base station determines activation third micro-base station at this time.

For example, if terminal is connected under macro base station, it is connected under micro-base station 1 simultaneously, target BS is micro-base station 2, the information for being used to indicate link change that terminal is sent is to be used to indicate the instruction information for increasing link for terminal, refer to that terminal needs to establish at this time a new link between terminal and micro-base station 2 But the link between terminal and macro base station does not turn off, the link between terminal and micro-base station 1 is disconnected not to be turned off, and is not processed at this to the link between terminal and micro-base station 1；

Terminal receives source base station and sends radio resource control RRC connection configuration order；Terminal sends RRC connection configuration to source base station and completes response after carrying out RRC connection configuration according to RRC connection configuration order.

Target BS changes to source base station transmission link requests；Target BS receives the link change response that source base station returns；Target BS receives the link change process that source base station is sent and completes order；

Optionally, if source base station is micro-base station:

After target BS receives the link change response that source base station returns, target BS receives source base station hair The link change process sent is completed before order, further includes: conversion carrying path between target BS and source base station.
