本发明涉及无线通信技术领域，具体涉及更新激活集的方法、系统、无线接入终端及网络服务端。The invention relates to the technical field of wireless communication, in particular to a method and system for updating an active set, a wireless access terminal and a network server.
背景技术Background technique
无线接入终端通常可以处于三种状态：即非激活态、空闲态和连接态。非激活态一般是指无线接入终端(AT)刚开机捕获网络，马上要转移到空闲态的一种状态；空闲态是指AT捕获网络后，已经与网络同步并且可以随时进行呼叫的状态；连接态则是指AT建立连接以后的状态。在空闲态时，AT自动对收到的所有导频进行管理；而在连接态时，AT和无线接入网络服务端(AN)相互配合对所有的导频信号进行管理。其中，在连接态时，将所有的导频信号分成激活集、候选集、相邻集和剩余集。其中激活集就是当连接建立时，所有正在对AT进行服务的导频信号；而连接关闭时，AT将只监听激活集中导频的控制信道。候选集则是所有可以随时进入激活集的导频组成，是激活集的候选。一般激活集和候选集的管理都是通过一定的门限来进行，即超过一定门限，则可以将候选集的导频加入激活集，否则，将激活集的导频从激活集搬到候选集中。A wireless access terminal can generally be in three states: an inactive state, an idle state and a connected state. The inactive state generally refers to a state in which the wireless access terminal (AT) has just started to capture the network and is about to transfer to the idle state; the idle state refers to the state in which the AT has synchronized with the network and can make calls at any time after capturing the network; The connected state refers to the state after the AT establishes a connection. In the idle state, the AT automatically manages all received pilot signals; while in the connected state, the AT and the wireless access network server (AN) cooperate with each other to manage all pilot signals. Wherein, in the connected state, all pilot signals are divided into active set, candidate set, adjacent set and residual set. The active set is all the pilot signals that are serving the AT when the connection is established; and when the connection is closed, the AT will only monitor the control channel of the pilot in the active set. The candidate set is composed of all pilots that can enter the active set at any time, and is a candidate for the active set. Generally, the management of the active set and the candidate set is carried out through a certain threshold, that is, if the threshold exceeds a certain threshold, the pilot of the candidate set can be added to the active set; otherwise, the pilot of the active set is moved from the active set to the candidate set.
在3GPP2(3rd Generation Partnership Project 2，第三代移动通信合作项目组织2)的演进项目LBC(松散的后向兼容)中，前反向数据传输使用OFDMA(Orthogonal Frequency Division Multiplexing Access，正交频分多址)技术。并且前反向数据传输都是采用某个特定扇区服务的方式，即存在前向服务扇区和反向服务扇区。而服务扇区选择的依据则是根据扇区导频强度，扇区负荷等因素综合考虑，由扇区对应的AN来进行分配。因此在LBC中，也存在激活集管理，即AT可能同时监听到多个强度很强的不同扇区的导频信号，并且它们同时被加入AT的激活集。一种AT与扇区的通信如图1所示：In the evolution project LBC (loose backward compatibility) of 3GPP2 (3rd Generation Partnership Project 2, the third generation mobile communication cooperation project organization 2), the forward and reverse data transmission uses OFDMA (Orthogonal Frequency Division Multiplexing Access, orthogonal frequency multiple access) technology. In addition, the forward and reverse data transmission adopts a specific sector service mode, that is, there are forward serving sectors and reverse serving sectors. The basis for selecting the serving sector is based on comprehensive consideration of factors such as sector pilot strength and sector load, and allocation is made by the AN corresponding to the sector. Therefore, in LBC, there is also active set management, that is, the AT may simultaneously monitor the pilot signals of multiple strong sectors in different sectors, and they are added to the AT's active set at the same time. A communication between an AT and a sector is shown in Figure 1:
AT能够测量到3个扇区：扇区1、扇区2和扇区3，其中扇区1是AT的服务扇区，那么AT将从扇区1接收和发送数据，但是由于AT的移动性，AT还必须不断的测量扇区2和扇区3的导频强度，以便随时选择更好的扇区进行前向服务，另外AT还必须发送反向导频到扇区2和扇区3，通过每个扇区测量反向导频强度，并且反馈给AT，从而可以选择最好的反向服务扇区。AT can measure 3 sectors: sector 1, sector 2 and sector 3, where sector 1 is the serving sector of AT, then AT will receive and send data from sector 1, but due to the mobility of AT , AT must also constantly measure the pilot strength of sector 2 and sector 3, so as to select a better sector for forward service at any time, and AT must also send reverse pilot to sector 2 and sector 3, through Each sector measures the reverse pilot strength and feeds it back to the AT so that the best reverse serving sector can be selected.
在现有LBC的连接态激活集管理实现中，对激活集中的导频进行更新的方法如图2所示：In the implementation of the active set management in the connected state of the existing LBC, the method for updating the pilots in the active set is shown in Figure 2:
步骤201、AT向AN发送导频报告(PilotReport)消息；Step 201, AT sends pilot report (PilotReport) message to AN;
AT通过不断测量来自相邻扇区的前向导频，并且上报PilotReport消息给AN，由AN来进行激活集成员的管理，即决定增加某些导频进入激活集或者从激活集中删除某些导频。这是一种完全由AN来进行控制的手段。通过设置门限PilotDrop，当AT检测到某个导频的导频强度低于PilotDrop，则启动一个定时器，定时时长为PilotDropTimer，如果定时器超时，该导频的强度一直低于PilotDrop，则AT会发送PilotReport消息给AN，请求AN从激活集中删除该导频；此时即使导频的强度非常低，现有的无线接入终端也不能删除该导频，而需要得到AN的指示才对其进行删除；相应的，AN也需要提供更多的系统资源来重新进行激活集的指配。AT continuously measures the forward pilots from adjacent sectors and reports the PilotReport message to AN, and AN manages the members of the active set, that is, it decides to add some pilots to the active set or delete some pilots from the active set . This is a means that is completely controlled by the AN. By setting the threshold PilotDrop, when the AT detects that the pilot strength of a certain pilot is lower than PilotDrop, it starts a timer with a timing duration of PilotDropTimer. If the timer expires and the strength of the pilot is always lower than PilotDrop, AT will Send a PilotReport message to the AN, requesting the AN to delete the pilot from the active set; at this time, even if the strength of the pilot is very low, the existing wireless access terminal cannot delete the pilot, and needs to be instructed by the AN to proceed Correspondingly, the AN also needs to provide more system resources to reassign the active set.
步骤202、AN向AT返回资源指配(MACResourceAssignment)消息；Step 202, AN returns a resource assignment (MACResourceAssignment) message to AT;
AN根据接收到的PilotReport消息确定可以从激活集中删除该导频，通过资源指配消息通知AT，也就是通过消息重新进行激活集的指配；AN determines that the pilot can be deleted from the active set according to the received PilotReport message, and notifies AT through the resource assignment message, that is, reassigns the active set through the message;
步骤203、AT向AN发送MACResourceAssignmentComplete(资源指配响应)消息；Step 203, AT sends MACResourceAssignmentComplete (resource assignment response) message to AN;
AT从激活集中删除了对应的导频后，通知AN，AN也从自身维护的激活集中删除对应的导频，从而保证AT和AN维护的激活集一致。After the AT deletes the corresponding pilot from the active set, it notifies the AN, and the AN also deletes the corresponding pilot from the active set maintained by itself, so as to ensure that the active sets maintained by the AT and the AN are consistent.
使用上述方法可以实现对激活集的更新，但是在某些情况下，例如随着AT的移动，AT如果检测到某个导频的强度已经很弱，AT仍然需要通过先上报PilotReport，然后由AN重新下发资源指配来指示AT删除该导频，处理过程比较繁琐；并且新的资源指配消息要携带很多的控制信息，导致了较多的传输信令开销；而且在下发新的资源指配消息时，AN并没有进行删除激活集中导频的处理，而是要等收到AT发送的资源指配的响应消息后，AN才会删除自身维护的激活集中的导频，进一步加大了处理的繁琐程度；进一步，现有的无线接入终端不能主动的从激活集中删除不符合条件的导频，而必须得到AN的指示才能对其删除，加大了处理的复杂度；相应的，AT不能主动删除导频，必然会导致AN的处理复杂性，使现有的AN需要较多的处理资源来指示AT对导频进行删除。The above method can be used to update the active set, but in some cases, for example, as the AT moves, if the AT detects that the strength of a certain pilot is already weak, the AT still needs to report the PilotReport first, and then the AN Re-issue resource assignment to instruct AT to delete the pilot, the process is cumbersome; and the new resource assignment message will carry a lot of control information, resulting in more transmission signaling overhead; When assigning messages, the AN does not delete the pilots in the active set, but waits for the resource assignment response message sent by the AT before deleting the pilots in the active set maintained by the AN, which further increases the The complexity of processing; further, the existing wireless access terminal cannot actively delete pilots that do not meet the conditions from the active set, but must be instructed by the AN to delete them, which increases the complexity of processing; correspondingly, The AT cannot actively delete the pilot, which will inevitably lead to the processing complexity of the AN, so that the existing AN needs more processing resources to instruct the AT to delete the pilot.

具体实施方式Detailed ways
为使本发明的目的、技术方案、及优点更加清楚明白，以下参照附图并举实施例，对本发明进一步详细说明。In order to make the object, technical solution, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples.
参见图3，本发明提供的方法的第一实施例主要包括：Referring to Fig. 3, the first embodiment of the method provided by the present invention mainly includes:
步骤301、AT监测到一个导频符合预置的删除条件；
预置的删除条件可以有多种情况，例如导频信号的强度较弱，或者导频信号失去与扇区的前向同步等情况；本说明书都是采用监测到一个导频的情况进行说明，如果同时监测到多个导频符合预置的删除条件，处理方式也和一个时的处理方式相同，以下以导频信号的强度较弱为例进行说明：The preset deletion conditions can have many situations, such as the strength of the pilot signal is weak, or the pilot signal loses the forward synchronization with the sector, etc.; this manual uses the situation of monitoring a pilot to illustrate, If multiple pilots are detected at the same time and meet the preset deletion conditions, the processing method is the same as that of one. The following takes the weak pilot signal strength as an example to illustrate:
在连接态情况下，AT与激活集中多个扇区的前向保持同步，并且监听来自多个扇区的前向导频，测量这些导频的信号强度，在一般情况下，估计导频信号强度可以使用Ec/Io来表示，即单位chip上接收到的导频能量与所有接收信号谱密度之比；一般情况下，AT还会对这些导频强度进行信号处理，比如滤波。通过在一段时间内的测量，如果AT发现某些激活集导频的信号强度低于预置的删除门限(PilotRemove)，PilotRemove与PilotDrop不同，一般来说，PilotRemove的值设置的比PilotDrop的值小，如果导频强度小于PilotDrop的值但是大于PilotRemove的值，此时还可以按照现有技术的流程进行处理，也就是Pilot的最后删除由AN来确定；如果Pilot的值小于PilotRemove的值，则AT可以立即从激活集中删除这个Pilot；至于Pilot的值等于PilotRemove的值的情况，可以直接删除也可以不直接删除，这个可以由技术人员根据具体情况进行设置；In the connected state, the AT is synchronized to the forward direction of multiple sectors in the active set, and listens to the forward pilots from multiple sectors, measures the signal strength of these pilots, and in general, estimates the pilot signal strength It can be represented by Ec/Io, which is the ratio of the pilot energy received on the unit chip to the spectral density of all received signals; under normal circumstances, AT will also perform signal processing on these pilot strengths, such as filtering. Through measurement over a period of time, if the AT finds that the signal strength of some active set pilots is lower than the preset deletion threshold (PilotRemove), PilotRemove is different from PilotDrop. Generally speaking, the value of PilotRemove is set smaller than the value of PilotDrop , if the pilot strength is less than the value of PilotDrop but greater than the value of PilotRemove, it can also be processed according to the process of the prior art, that is, the final deletion of Pilot is determined by AN; if the value of Pilot is less than the value of PilotRemove, then AT The Pilot can be deleted from the activation set immediately; as for the case where the value of the Pilot is equal to the value of PilotRemove, it can be deleted directly or not directly, which can be set by the technician according to the specific situation;
当然，这只是本发明提供的一种比较优选的实现方式，在实际应用中，也可以将PilotRemove直接取代PilotDrop，也就是采用本发明实施例提供的技术方案完全取代现有技术，只要测得Pilot的强度小于预置的PilotRemove就直接删除；Of course, this is only a relatively preferred implementation mode provided by the present invention. In practical applications, PilotRemove can also be directly replaced by PilotDrop, that is, the technical solution provided by the embodiment of the present invention is used to completely replace the prior art. If the intensity is less than the preset PilotRemove, it will be deleted directly;
步骤302、所述AT从激活集中删除所述导频；
如果AT测得所述导频满足预置的删除条件，如所述导频的强度小于预置的PilotRemove，或者所述导频失去了与扇区的前向同步，都将所述导频从所述AT维护的激活集中删除所述导频；If the AT detects that the pilot meets the preset removal conditions, for example, the strength of the pilot is less than the preset PilotRemove, or the pilot loses forward synchronization with the sector, the pilot will be removed from the deleting the pilot from the active set maintained by the AT;
步骤303、所述AT将删除的所述导频的信息通知AN；
可以新增加一个导频删除消息，消息中携带待删除导频的标识，可以将该消息命名为PilotRemove，在消息中携带的待删除导频的标识包括导频的PN(PilotPN)和载波ID(CarrierID)，PilotPN和CarrierID可以唯一确定一个导频，因此只需要在PilotRemove消息中携带PilotPN和CarrierID以及必要的通信消息，从而减少不必要的信令传输开销；此处虽然将消息命名为PilotRemove，但是本发明的实施例并不对消息名称进行限定；A new pilot deletion message can be added, the message carries the identifier of the pilot to be deleted, and the message can be named PilotRemove, and the identifier of the pilot to be deleted carried in the message includes the pilot PN (PilotPN) and the carrier ID ( CarrierID), PilotPN and CarrierID can uniquely determine a pilot, so it is only necessary to carry PilotPN and CarrierID and necessary communication messages in the PilotRemove message, thereby reducing unnecessary signaling transmission overhead; although the message is named PilotRemove here, but The embodiment of the present invention does not limit the name of the message;
进一步的，本发明提供了另外一种实施方式，将删除的导频的信息通知AN；该方式不需要增加新的消息，而是在现有流程的基础上实现；如表1所示，是现有流程中PilotReport消息的格式：Further, the present invention provides another implementation mode, which notifies the AN of the deleted pilot information; this mode does not need to add new messages, but is implemented on the basis of the existing process; as shown in Table 1, it is The format of the PilotReport message in the existing process:
表1、现有PilotReport消息格式Table 1. Existing PilotReport message format
对现有的PilotReport消息进行修改，例如可以在Keep字段前新增加Removed字段，该字段占用一个比特，当Removed字段为1时，表示AT已将该导频删除；如果Removed字段为0，则表示AT没有删除该导频，由AN做进一步的指示是否删除该导频；本实施例并不排除使用Removed字段为0表示已经删除，而采用字段为1时为未删除的情况；Modify the existing PilotReport message. For example, you can add a Removed field before the Keep field. This field occupies one bit. When the Removed field is 1, it means that the AT has deleted the pilot; if the Removed field is 0, it means The AT does not delete the pilot, and the AN further indicates whether to delete the pilot; this embodiment does not exclude the use of the Removed field as 0 to indicate that it has been deleted, and when the field is 1, it is not deleted;
修改后的PilotReport消息格式如表2所示：The modified PilotReport message format is shown in Table 2:
表2、本发明提供的PilotReport消息格式Table 2, PilotReport message format provided by the present invention
表2只是本实施例提供的一种消息格式方案，本实施例并不排除在其他位置添加其他字段名称的字段来表示AT是否对该导频进行了删除；Table 2 is only a message format scheme provided by this embodiment, and this embodiment does not rule out adding fields with other field names in other positions to indicate whether the AT has deleted the pilot;
步骤304、所述AN根据所述导频的信息，从为所述AT维护的激活集中删除所述导频；
AN收到AT发送的删除的导频的信息后，从自身维护的激活集中删除对应的导频；After AN receives the deleted pilot information sent by AT, it deletes the corresponding pilot from the active set maintained by itself;
如果AN收到的是新增的PilotRemove消息，就根据所述消息携带的PilotPN和CarrierID两个字段唯一确定需要删除的导频；If the AN receives the newly added PilotRemove message, it uniquely determines the pilot to be deleted according to the PilotPN and CarrierID fields carried by the message;
如果AN收到的是原有的PilotReport消息，则判断新增的字段Removed是否为1，如果Removed为1，则表示AT删除了对应的导频，AN就根据PilotReport消息中的PilotPN和ChannelBand两个字段唯一确定需要删除的导频，其中ChannelBand和CarrierID是一一对应的；If AN receives the original PilotReport message, it will judge whether the newly added field Removed is 1. If Removed is 1, it means that AT has deleted the corresponding pilot, and AN will use PilotPN and ChannelBand in the PilotReport message The field uniquely determines the pilot to be deleted, where ChannelBand and CarrierID are in one-to-one correspondence;
在本发明提供的方法的第一实施例中，AT测得一个导频符合预置的删除条件时，直接从激活集中删除该导频，再通知AN对所述导频进行删除，因而采用简单的流程实现了对导频进行了删除，进一步，由于流程减少，也减少了信令传输所需要的开销；在第一实施例的一种实现方式中，采用了新增的消息PilotRemove，在该消息中只携带了少数的几个字段，进一步减少了信令传输所需要的开销。In the first embodiment of the method provided by the present invention, when the AT detects that a pilot meets the preset deletion condition, it directly deletes the pilot from the active set, and then notifies the AN to delete the pilot. Therefore, a simple The process realizes that the pilot is deleted, and further, due to the reduction of the process, the overhead required for signaling transmission is also reduced; in an implementation of the first embodiment, the newly added message PilotRemove is used, and in this Only a few fields are carried in the message, which further reduces the overhead required for signaling transmission.
在实际应用中，AN从激活集中删除了对应的导频后，将会给AT返回一个确认消息，通知AT已经对所述导频进行了删除，从而使AT确认AT和AN分别维护的激活集保持一致；如果所述导频归属于为所述AT服务的服务扇区，则AN可以直接通过所述服务扇区通知所述AT已经从激活集中删除对应的导频；如果所述导频归属于为所述AT服务的非服务扇区，则所述AN需要通过所述非服务扇区将已经从激活集中删除对应导频的信息，转发给为所述AT服务的服务扇区，再由所述服务扇区将信息转发给所述AT。In practical applications, after AN deletes the corresponding pilot from the active set, it will return a confirmation message to AT, informing AT that the pilot has been deleted, so that AT can confirm the active sets maintained by AT and AN respectively. Keep consistent; if the pilot belongs to the serving sector serving the AT, the AN can directly notify the AT through the serving sector that the corresponding pilot has been deleted from the active set; if the pilot belongs to For the non-serving sector serving the AT, the AN needs to forward the information that the corresponding pilot has been deleted from the active set to the serving sector serving the AT through the non-serving sector, and then The serving sector forwards information to the AT.
针对第一实施例中的两种实现方式，AN对应有两种方式通知AT：如果AT使用新增加的PilotRemove通知AN，则AN对应的使用新增加的导频删除响应消息返回给AT，例如可以将所述导频删除响应消息命名为PilotRemoveRsp；如果AT是使用现有的PilotReport消息，通过在所述PilotReport消息中新增Removed字段，AN收到PilotReport消息后，判断Removed字段的值是否表示AT已经删除对应的导频，如果否，AN按照现有技术的正常流程进行处理；如果是，AN也删除对应的导频，并采用现有的MACResourceAssignment消息通知AT，当然也不排除采用新增消息对AT进行通知的情况。For the two implementations in the first embodiment, there are two ways for the AN to notify the AT: if the AT uses the newly added PilotRemove to notify the AN, then the AN correspondingly uses the newly added PilotRemove response message to return to the AT, for example, The pilot frequency deletion response message is named as PilotRemoveRsp; if the AT uses the existing PilotReport message, by adding the Removed field in the PilotReport message, after the AN receives the PilotReport message, it is judged whether the value of the Removed field indicates that the AT has Delete the corresponding pilot, if not, the AN will process it according to the normal process of the prior art; if yes, the AN will also delete the corresponding pilot, and use the existing MACResourceAssignment message to notify the AT, of course, it does not rule out the use of a new message to Situation of notification by AT.
参见图4，本发明提供的方法第二实施例主要包括以下步骤：Referring to Fig. 4, the second embodiment of the method provided by the present invention mainly includes the following steps:
步骤401、AT监测到一个导频符合预置的删除条件；
步骤402、所述AT从激活集中删除所述导频；
步骤403、所述AT将删除的所述导频的信息以及与所述预置的删除条件对应的删除原因通知AN；
删除原因可以在如方法第一实施例中所述的PilotRemove消息或PilotReport消息中增加一个删除原因字段，字段的长度可以根据已知的删除原因的数量进行设定；举个例子，假如已知有两种删除原因，则可以将字段长度设置为2，用00表示没有删除，01表示导频强度太低，10表示导频失去了与扇区的前向同步，11表示删除原因未知；AN收到消息后，根据删除原因字段的值就可以知道对应的删除原因；当然也不排除采用一个新的消息单独发送删除原因的情况；Deletion reason can add a deletion reason field in the PilotRemove message or PilotReport message as described in the first embodiment of the method, and the length of field can be set according to the quantity of known deletion reason; For example, if known If there are two reasons for deletion, you can set the field length to 2, use 00 to indicate no deletion, 01 to indicate that the pilot strength is too low, 10 to indicate that the pilot has lost forward synchronization with the sector, and 11 to indicate that the reason for deletion is unknown; AN accepts After receiving the message, you can know the corresponding deletion reason according to the value of the deletion reason field; of course, it does not rule out the case of using a new message to send the deletion reason separately;
步骤404、所述AN根据所述导频的信息从该AN维护的激活集中删除所述导频，触发所述导频对应的扇区根据所述删除原因作对应的处理；
AN收到AT发送的消息后，根据消息中删除原因字段的值确定删除原因，并触发所述导频对应的扇区作对应的处理；例如，如果删除原因是导频强度太低，就加大发射功率；如果是失去与扇区的前向同步，则调整系统时间；从而使扇区作对应的处理，避免再次出现相同的情况；After the AN receives the message sent by the AT, it determines the reason for the deletion according to the value of the deletion reason field in the message, and triggers the sector corresponding to the pilot to perform corresponding processing; for example, if the reason for deletion is that the pilot strength is too low, add High transmit power; if the forward synchronization with the sector is lost, adjust the system time; so that the sector can deal with it accordingly to avoid the same situation from happening again;
步骤405、AN将已经将所述导频从激活集中删除的信息通知AT；
AN删除了对应的导频后，通知AT，从而使AT知道二者的激活集是保持一致的；After AN deletes the corresponding pilot, it notifies AT, so that AT knows that the active sets of the two are consistent;
在第二实施例中，AT将删除导频的原因通知AN，从而使AN触发所述导频对应的扇区作对应的处理，避免了再次发生相同的情况。In the second embodiment, the AT notifies the AN of the reason for deleting the pilot, so that the AN triggers the sector corresponding to the pilot to perform corresponding processing, and avoids the same situation from happening again.
AT与扇区导频不断的进行通信，扇区导频为了保证与AT的通信正常，必须为所述AT分配一些资源来保障通信的正常进行，例如为AT分配的MACID，MAC ID是扇区导频用来唯一标识所述AT的，当然还有其它保障通信正常进行的其它必要的资源；但是扇区导频的资源是有限的，AT从激活集中删除了一个导频后，不会再与该导频进行通信，因而该导频为所述AT分配的资源就没有用了，所以为了节省扇区导频的资源，本发明提供的第三实施例在AT从激活集中删除了导频后，还包括步骤：The AT communicates with the sector pilot continuously. In order to ensure the normal communication with the AT, the sector pilot must allocate some resources to the AT to ensure the normal communication, such as the MACID assigned to the AT, and the MAC ID is the sector The pilot is used to uniquely identify the AT, and of course there are other necessary resources to ensure normal communication; however, the resource of the sector pilot is limited, and after the AT deletes a pilot from the active set, it will no longer Communicate with the pilot, so the resources allocated by the pilot to the AT are useless, so in order to save sector pilot resources, the third embodiment of the present invention deletes the pilot from the AT in the active set After that, also include the steps:
所述AT通知所述导频对应的扇区释放为所述AT分配的资源。The AT notifies the sector corresponding to the pilot to release the resource allocated for the AT.
扇区释放了为所述AT分配的资源后，扇区可以用这些资源为其它的AT服务，从而保证了扇区资源的充分利用。After the sector releases the resources allocated for the AT, the sector can use these resources to serve other ATs, thus ensuring full utilization of sector resources.
AT可能同时与多个扇区的多个导频进行通信，但是同时只能有一个扇区为服务扇区，其他的扇区则是非服务扇区；AT may communicate with multiple pilots of multiple sectors at the same time, but only one sector can be the serving sector at the same time, and the other sectors are non-serving sectors;
图5描述的是本发明提供的方法的第三实施例，主要描述的是导频归属于AT的非服务扇区的情况：Figure 5 describes the third embodiment of the method provided by the present invention, mainly describing the situation that the pilot belongs to the non-serving sector of the AT:
步骤501、AT监测到一个归属于非服务扇区的导频符合预置的删除条件；Step 501, the AT detects that a pilot belonging to a non-serving sector meets a preset deletion condition;
步骤502、AT从激活集中删除所述导频，并将所述导频的信息、与所述删除条件对应的删除原因和所述非服务扇区标识发送给AT的服务扇区；Step 502, the AT deletes the pilot from the active set, and sends the pilot information, the deletion reason corresponding to the deletion condition, and the non-serving sector identifier to the serving sector of the AT;
所述非服务扇区标识是只要可以唯一标识所述非服务扇区的信息都可以，如扇区ID等；The non-serving sector identifier is any information that can uniquely identify the non-serving sector, such as a sector ID, etc.;
步骤503、所述服务扇区根据所述非服务扇区标识将所述导频的信息以及与所述删除条件对应的删除原因转发给所述非服务扇区；Step 503, the serving sector forwards the pilot information and the deletion reason corresponding to the deletion condition to the non-serving sector according to the non-serving sector identifier;
这里只描述了服务扇区可以直接将信息转发给所述非服务扇区的情况，但是不排除服务扇区不能直接将信息转发给所述非服务扇区，而需要经过多次转发的情况；This only describes the situation that the serving sector can directly forward the information to the non-serving sector, but it does not rule out the situation that the serving sector cannot directly forward the information to the non-serving sector, but needs to go through multiple forwarding;
步骤504、所述非服务扇区根据所述导频的信息从为所述AT服务的激活集中删除所述导频，根据所述删除原因作对应的处理；Step 504, the non-serving sector deletes the pilot from the active set serving the AT according to the pilot information, and performs corresponding processing according to the deletion reason;
由上可知，当导频归属于AT的非服务扇区时，可以通过服务扇区将信息转发给所述非服务扇区，从而使激活集的更新能够顺利进行；It can be seen from the above that when the pilot belongs to the non-serving sector of the AT, the information can be forwarded to the non-serving sector through the serving sector, so that the update of the active set can be carried out smoothly;
进一步的，非服务扇区释放为AT分配的资源也是通过服务扇区触发的，如图1所示：Further, the non-serving sector releases the resource allocated for AT is also triggered by the serving sector, as shown in Figure 1:
假设服务扇区是扇区1，AT从激活集中删除了扇区2的一个导频；此时AT不能与扇区2直接通信，所以AT从激活集中删除了扇区2的一个导频后，先通知扇区1，再由扇区1通知扇区2释放为所述AT分配的资源，从而使扇区2的有限资源能够被充分利用。Assuming that the serving sector is sector 1, AT deletes a pilot of sector 2 from the active set; at this time, AT cannot communicate directly with sector 2, so after AT deletes a pilot of sector 2 from the active set, The sector 1 is notified first, and then the sector 1 notifies the sector 2 to release the resources allocated for the AT, so that the limited resources of the sector 2 can be fully utilized.
