Description

一种切换控制方法、终端、源基站及目标基站 A control method for a terminal, the source base station and target base station handover

技术领域 FIELD

[0001] 本发明涉及移动通信技术领域,具体涉及一种切换控制方法、终端、源基站及目标基站。 [0001] The present invention relates to the technical field of mobile communications, particularly to a handover control method, a terminal, a source base station and target base station.

背景技术 Background technique

[0002] 数据通f目中应用程序专属拥塞控制(ACDC,Application specific Congestion control for Data Communication)是一种接入控制机制,运营商可以允许或者阻止用户设备(UE)空闲态时特定应用程序的接入请求。 [0002] f mesh data through the application-specific congestion control (ACDC, Application specific Congestion control for Data Communication) is an access control mechanism, the operator can allow or block a particular application when a user equipment (UE) in idle state access request. ACDC只适用于空闲态的UE,不适用于连接态的UE,其作用是减轻接入网或核心网的负载超载,ACDC的基本特性如下: ACDC UE only applies to the idle state, connected state not applicable for the UE, its role is overloaded to reduce the load of the access network or core network, ACDC basic characteristics are as follows:

[0003] 1 .ACDC适用于通用移动通信系统地面无线接入网(UTRAN)和演进UTRAN(E-UTRAN)〇 [0003] 1 .ACDC applicable to Universal Mobile Telecommunications System Terrestrial Radio Access Network (UTRAN) and Evolved UTRAN (E-UTRAN) square

[0004] 2.家乡网络为UE配置至少4个ACDC类别,分别对应到运营商定义的应用。 [0004] 2. The home network for the UE is configured ACDC least four categories that correspond to the application operator-defined.

[0005] 3 •开通UE内的A⑶C类别是家乡网络的义务,如何分类不受3GPP定义。 A⑶C category in the [0005] 3 • opened UE is the obligation of the home network, how to classify is not defined by 3GPP.

[0006] 4. UE有一套机制来验证为其开通ACDC类别的是一个受信源。 [0006] 4. UE have a mechanism to verify its opening ACDC category is a trusted source.

[0007] 5 •服务网络在接入网侦彳广播控制信息,包括:每一个ACDC类别的阻拦信息、一个漫游的UE是否应该受限于A⑶C控制。 [0007] 5 • service network in the access network reconnaissance left foot broadcast control information, including: ACDC each category of information block, a roaming UE whether it should be limited to A⑶C control.

[0008] 6.每个小区内广播的阻拦信息是不同的,UE内应用与M:DC类别的对应关系由家乡网络配置。 [0008] 6. The information broadcast in each cell block are different, the UE applies the M: DC category corresponding relationship configured by the home network.

[0009] 7.基于广播的这个阻拦信息和UE内部的ACDC类别配置,UE可以决定是否允许特定应用的接入请求的传输。 [0009] 7. The blocking categories based ACDC broadcast information and internal configuration of the UE, UE can decide whether to allow access to a particular application of the transfer request.

[0010] 8.服务网络应该在执行其他接入控制的同时指示ACDC,当ACDC和接入类型受限(ACB,Access Class Barring)控制同时指不时,ACDC应该覆盖ACB。 [0010] 8. The network shall indicate ACDC service while performing access control in the other, and when the access type is limited ACDC (ACB, Access Class Barring) while the control means from time to time, should cover ACDC ACB.

[0011] 9.在多个核心网共享同一个接入网时,接入网应该可以为不同的核心网分别单独执行ACDC。 [0011] 9. A plurality of core network while sharing the same access network, the access network may be performed separately for different ACDC separate core network. 为了缓和一个共享的接入网的拥塞,为了公平,对不同的运营商的阻拦比率设置应该相同。 In order to ease the congestion of a shared access network, to be fair, it should be the same for different block ratios operators.

[0012] UE的操作系统为每一个应用程序分配应用程序标识(ID),UE通过接收家乡网络广播或者通过核心网的远程SIM卡写入,获得应用程序ID与ACDC类别的对应关系。 [0012] UE operating system for each application assigned application identification (ID), remote SIM UE by writing a core network by receiving a broadcast or home network, a corresponding relationship with the application ID ACDC category. 可能会有多个不同的应用程序ID对应一个ACDC类别。 There may be a plurality of different application ID corresponding to a category ACDC.

[0013] 家乡网络为UE配置ACDC应用类别: [0013] ACDC home network configuration application category for UE:

[0014] 1.被限制得最轻的应用(接入优先级最高),被配置为最高的ACDC类别,即为ACDC# 1; [0014] 1. The application is limited to be the lightest (highest access priority), configured to ACDC highest category, i.e. ACDC # 1;

[0015] 2•被限制得比ACDC#1多的应用,被配置为第二高的ACDC类别,即为ACDC#2;以此类推。 [0015] 2 • ACDC # 1 is larger than the limit number of applications, configured to ACDC second highest category, i.e. ACDC # 2; and so on.

[0016] 3.被限制得最多的应用(接入优先级最低),或者被配置为最低的ACDC类别,或者不配置ACDC类别。 [0016] 3. The application is limited to the most (lowest access priority), or configured to ACDC lowest category or categories ACDC not disposed.

[0017] UE上未被配置ACDC类别的应用,应该被UE认为是最低的ACDC类别。 [0017] ACDC application categories are not configured on the UE, UE should be regarded as the lowest category of ACDC. 当使用ACDC时, 服务网络广播阻拦信息,阻拦信息从ACDC类别的最高到最低依次发送。 When ACDC, service network broadcast information block, block information sent from ACDC category of highest to the lowest. 家乡网络和服务网络可能使用不同的分类方法。 Home network and service network may use different classification methods. 服务网络决定是否将ACDC应用到漫游的UE上。 ACDC service network to decide whether to apply to roaming UE.

[0018] UE上的ACDC类别个数可能和服务网络广播的A⑶C类别数不同。 [0018] ACDC number of categories on the UE and the number of possible network broadcast A⑶C different categories. 这种情况会发生于UE漫游时,服务网络广播的ACDC类别数与UE的家乡网络不同。 When this happens in UE roaming, ACDC number of categories of broadcast services network and the home network of the UE different. 因此,此时采用如下策略: Therefore, this time using the following strategies:

[0019] 1.如果服务网络广播的ACDC类别数比UE自身配置的多,UE使用与ACDC对应的阻拦信息,对于未分类别的应用采用服务小区广播中最低类别的阻拦信息。 [0019] 1. If the information block of a broadcast network service class configuration ACDC number more than the UE itself, the UE using the corresponding ACDC, unclassified other applications for use of the lowest class of service cell broadcast information block. 并忽视其他与自身ACDC类别不匹配的阻拦信息。 And ignore the other block information itself ACDC category does not match.

[0020] 2.如果服务网络广播的阻拦信息对应的ACDC类别数少于UE自身的配置,UE为匹配的ACDC类别采用对应的阻拦信息,对其他应用采用服务小区中最低类别的阻拦信息。 [0020] 2. If the number of categories ACDC network broadcast information block corresponding to the configuration than the UE itself, the UE using the block matching information corresponding to the ACDC category serving cell using the lowest blocking class information to other applications.

[0021] 这里,一个匹配的ACDC类别是指,服务网络广播的阻拦信息的ACDC类别排序与UE 自身配置的ACDC类别排序相同。 [0021] Here, a category ACDC matching means, the same ACDC ACDC Sort Sort UE and network broadcast service information block itself configuration.

[0022] 服务网络内的ACDC接入控制过程中,服务网络顺序广播不同类别的ACDC阻拦参数,包含“阻拦时间” “阻拦概率”,具体的, [0022] ACDC access control procedure in the network service, network order service broadcast different types of ACDC block parameters, including "stop time" "blocking probability" Specifically,

[0023] 阻拦时间:若应用程序a对应的ACDC类别为#1,广播的ACDC#1的阻拦时间为100ms, 则应用程序a的连接请求一旦被ACDC策略阻拦后,在接下来的阻拦时间100ms内,应用程序a 的连接请求将一直被阻拦。 [0023] The blocking time: a connection request if the application corresponding to ACDC category # 1, broadcast stop time ACDC # 1 is 100ms, the application of a policy ACDC is blocked once, the next time block 100ms the application has a connection request to be blocked.

[0024] 阻拦概率:若应用程序b对应的ACDC类别为#2,广播的A⑶C#2的阻拦概率为0.6,应用程序b发起连接请求时,UE为其生成0-1之间的随机数,若随机数小于或等于0.6,则允许接入,若大于0.6,则拒绝接入。 [0024] The blocking probability: If the application corresponding to b ACDC category # 2, A⑶C # 2 broadcast blocking probability is 0.6, b application initiates a connection request, the UE for generating a random number between 0 and 1, If the random number is less than or equal to 0.6, the access is allowed, if it exceeds 0.6, the access is denied.

[0025] 传统ACDC是空闲态的UE发起随机接入前,非接入层(NAS)层把服务请求(SR, Service Request)传下来给无线资源控制(RRC)层,包含ACDC类别(category) ;RRC层从系统消息中可以知道阻拦参数,RRC层执行ACDC判决。 [0025] Traditional ACDC before the idle state UE initiates a random access, a non-access stratum (NAS) layer of the Service Request (SR, Service Request) passed down to the radio resource control (RRC) layer, comprising ACDC category (category) ; from the RRC layer system information block can be known parameters, RRC layer performs ACDC judgment.

[0026] 然而当UE处于连接态时,由于已经建好用户面承载,UE会在应用层直接发数据, NAS层不再发SR请求给RRC层,因此连接态时发起的新业务不会通过ACDC。 [0026] However when a UE is in a connected state, since the user plane bearer has been completed, the UE will send the data directly to the application layer, the NAS layer request to the SR send no RRC layer, thus initiating a new service connection state not by ACDC.

[0027]由于传统ACDC只作用于空闲态的UE,而不作用于连接态的UE,这会导致搭便车的问题:由于ACDC只能在空闲状态做准入判决,当有一个应用被允许接入网络,与网络建立RRC连接;在RRC连接断开之前,其他低优先级的应用都不会再做ACDC判决,便可以绕过ACDC 判决,直接接入网络。 [0027] Since the conventional UE ACDC to act only on the idle state, the UE does not act on the connected state, which can lead to free-rider problems: Since only do ACDC access idle judgment, when there is an application is allowed to access to the network, the establishment of RRC connection with the network; before the RRC connection is broken, other low-priority applications will not do ACDC decision, they can bypass the ACDC judgment, direct access to the network. 显然,现有技术的ACDC不利于对不同的应用程序分别管控,不利于应用程序之间优先级的公平性。 Obviously, ACDC prior art is not conducive to different applications respectively control, is not conducive to the priority of fairness between applications.

[0028] 下面简单介绍现有技术中的切换流程,例如,3GPP TS36 • 300协议提供的一种切换流程如图1所示,包括以下步骤: [0028] The following outlines the prior art handover process, for example, a handover process 3GPP TS36 • 300 provided by the protocol shown in Figure 1, comprising the steps of:

[0029] 101)源基站向UE下发测量控制,通过RRC Connection Reconfigration消息对UE 的测量类型进行配置; [0029] 101) the source base station to send the UE measurement control, measurement type configure the UE by RRC Connection Reconfigration message;

[0030] 102) UE按照测量配置向基站上报测量报告; [0030] 102) UE reports a measurement report to the base station according to measurement configuration;

[0031] 103)源基站根据测量报告进行判决,判决该UE发生基站间切换,也有可能负荷分担的原因触发切换; [0031] 103) The source base station according to the measurement report which held inter-base station handover of the UE occurs, load balancing is also possible to cause the trigger switch;

[0032] 104)源基站向目标基站发生Handover Request消息,指示目标基站进行切换准备,切换请求消息包含源基站分配的Old eNB UE X2AP ID,MME分配的MME UE S1AP ID,需要建立的EPS承载列表以及每个EPS承载对应的核心网侧的数据传送的地址。 Handover Request message [0032] 104) the source base station occurs to the target base station, indicating that the target base station for handover preparation, the handover request message includes a source base station allocates the Old eNB UE X2AP ID, MME assigned MME UE S1AP ID, to be established EPS bearer list and the address data of each EPS bearer corresponding to the core network side of the transmission. 目标ENB收到Handover Request后开始对要切换入的e-RABs进行接纳处理; It starts to switch into the e-RABs receiving treatment for the target ENB receives Handover Request;

[0033] 105)目标基站进行接纳判决,为现的接入分配空口资源和业务的SAE承载资源; [0033] 105) for receiving the judgment target base station, an access bearer resource allocation for the current air interface resources and the SAE operations;

[0034] 106)目标基站资源准入成功后,向源基站发送切换请求确认Handover Request ACK消息,指示切换准备工作完成,“切换请求确认”消息包含New eNB UE X2AP ID、01d eNB UE X2AP ID、新建EPS承载对应在D侧上下行数据传送的地址、目标侧分配的专用接入签名等参数; [0034] 106) after a successful access to the target base station resources, the source base station sends a handover request acknowledgment Handover Request ACK message indicating handover preparation is completed, the "Handover Request Acknowledge" message comprising New eNB UE X2AP ID, 01d eNB UE X2AP ID, new EPS bearer corresponding to uplink and downlink data transmission in the D side address, the access target side allocated dedicated signature parameter;

[0035] 107)源基站向终端发送RRC连接重配置(RRC Connection Reconfiguration)消息,终端接收到RRC Connection Reconfiguration消息后,从源基站中去附着,然后通过随机接入过程与目标基站建立同步。 [0035] 107) to the source base station sends the terminal RRC Connection Reconfiguration (RRC Connection Reconfiguration) message, the terminal receives the RRC Connection Reconfiguration message, detach from the source base station, and establishes synchronization through a random access procedure with the target base station. 为节约篇幅,对于后续步骤不再详细说明。 To save space, for the subsequent steps will not be described in detail.

[0036]从现有技术的切换方案的接纳控制(步骤1〇1〜105)来看,目标基站只根据源基站发来的E-RAB QoS信息进行接纳控制,并没有考虑UE当前的应用程序(APP)。 [0036] The target base station only admission control according to the source base station is sent information from the E-RAB QoS admission control scheme of the prior art handover (step 1〇1~105) point of view, it does not consider the current application UE (APP). 比如,文字聊天和在线看视频两种应用,它们各自的E-RAB QoS等级可能相同,但对网络资源的消耗有着明显区别。 For example, text chat and watch video online two applications, each of the E-RAB QoS levels may be the same, but the consumption of network resources, there is a clear difference. 另一方面,源小区与目标小区的ACDC阻拦参数配置也可能不同,比如源小区对某视频程序的阻拦参数是完全通过,而目标小区由于某些原因对该视频程序的阻拦较高,切换时如果不考虑ACDC阻拦参数,不利于目标小区的公平性。 On the other hand, the ACDC source cell block parameters with the target cell may be different, such as source cell block parameters for a video program is completely through, but the higher the target cell for some reason stop the video program, when the switch If you do not consider ACDC block parameters, it is not conducive to the fairness of the target cell.
