Description

一种实现增强上行专用信道切换的方法技术领域 BACKGROUND enhancement method for implementing uplink dedicated channel switching

[0001] 本发明涉及高速上行链路分组接入(HSUPA,High Speed Uplink PacketAccess) 技术,尤指一种实现增强上行专用信道(E-DCH,Enhanced UplinkDCH)切换的方法。 [0001] The present invention relates to high speed uplink packet access (HSUPA, High Speed ​​Uplink PacketAccess) technology, particularly to a method for implementing the enhanced uplink dedicated channel (E-DCH, Enhanced UplinkDCH) handover. 背景技术 Background technique

[0002]对于版本 99(Release99)或Release4 的宽带码分多址接入(WCDMA,Wide-band Code Division Multiple Access)系统,承载业务的上下行容量比较有限,理论上不超过2Mbps,单个用户的实际吞吐率比较低,通常允许的最大传输速率为384Kbps。 [0002] For the version 99 (Release99) or Wideband Code Division Multiple Access Release4 of (WCDMA, Wide-band Code Division Multiple Access) system, uplink and downlink bearer service capacity is limited, theoretically no more than 2Mbps, a single user the actual throughput is relatively low, generally the maximum allowable transmission rate of 384Kbps. 而实际使用的传输速率往往达不到这么高的速率,这对提供高速数据业务的服务来说,存在明显不足。 The transmission rate is often less than the actual use of such a high rate, this service provides high-speed data services, the existence of significant deficiencies.

[0003] 第三代移动通信技术的主要目的是提供比较大的传输带宽,保证用户传输高速多媒体业务。 [0003] The main purpose of the third generation mobile communication technologies to provide a relatively large transmission bandwidth, to ensure that users transmit high-speed multimedia service. 为了进一步提高频谱利用率,更好的开展多媒体通信和包数据传输,继Release 标准中引入了提高下行容量和传输速率的高速下行链路分组接入(HSDPA)技术后,第三代合作伙伴计划(3GPP)组织在制定的Releasee标准中引入了HSUPA技术。 To further improve the spectrum efficiency, better carry out the packet data transmission and multimedia communications, following the standard Release introduced to improve the downlink capacity and the transmission rate of high speed downlink packet access (HSDPA) technology, the Third Generation Partnership Project (3GPP) organization introduces HSUPA technology in Releasee standard setting in. HSUPA采用基站NodeB的上行快速调度、混合自动请求重传(HARQ)、2ms短帧等技术,同时还新增了一个上行专用信道即E-DCH来支持HSUPA的传输。 HSUPA uses an uplink base station NodeB fast scheduling, hybrid automatic repeat request (HARQ), 2ms short frame technology, and also adds one uplink channel that is dedicated to support HSUPA E-DCH transmission. 采用E-DCH来传输数据,使得用户的上行吞吐率获得了极大的提高,理论上支持最高峰值速率达到5. 76Mbps,系统上行容量也获得了很大的提升。 Using the E-DCH data to transmit, so that the user uplink throughput was greatly improved, theoretically supports rates up to the highest peak 5. 76Mbps, the capacity of the system up also achieved a significant improvement.

[0004] 通常,当业务量大时,为了提高上行传输速率,采用E-DCH传输数据,而当业务量减少时,为了降低对无线功率和码资源的消耗,应该将采用E-DCH传输的数据切换到由低速信道如DCH/FACH/PCH传输,即进行信道切换。 [0004] Generally, when the traffic volume, in order to enhance the rate of uplink transmission using E-DCH transmission data, while reducing the amount of traffic, in order to reduce the power consumption of wireless resources and the code should be transmitted using the E-DCH switching to a low-speed data channel such as DCH / FACH / PCH transmission, i.e. channel switching. 其中,DCH为专用信道,FACH为前向接入信道,PCH为寻呼信道,本文所提到的低速信道是相对于E-DCH而言的信道。 Wherein, DCH is a dedicated channel, the FACH as a forward access channel, the PCH for the paging channel, low-rate channel is referred to herein in terms of relative channel E-DCH.

[0005] 为了保证信道切换的成功率,在进行信道切换之前,应该分别对切换前后的信道进行测量,获知目前承载在各信道上的实际业务量,并根据该实际业务量决定是否进行切换,只有当信道满足4B事件标准,即信道上承载的业务量均低于某个预设绝对门限值时, 才进行信道切换。 [0005] In order to ensure the success rate of the channel switching, prior to the channel switching, should each channel before and after switching of measurement, known currently as the actual traffic carried in each channel, and determine whether to switch the basis of the actual traffic, 4B only when the channel is satisfied event criteria, i.e. bearer channel traffic volume is below a predetermined threshold absolute, before channel switching.

[0006] 按目前的协议规定,对于上行信道,用户终端(UE)只能对随机接入信道(RACH), DCH或时分双工(TDD)模式下的上行共享信道(USCH)进行测量,也就是说,当UE使用E-DCH 时,由于协议中未规定对该E-DCH进行测量,因此,UE不能上报承载在E-DCH上的实际业务量,这样,当前上行使用E-DCH,且当上行业务量减少时: [0006] At the current agreement, for uplink channel, the user terminal (UE) only on the random access channel (the RACH), uplink shared channel (the USCH) under DCH or time division duplex (TDD) mode for measurement, and That is, when the UE using the E-DCH, since no predetermined protocol of the E-DCH is measured, therefore, UE can not report actual traffic carried on the E-DCH, so that, using the current uplink E-DCH, and when reducing the amount of uplink traffic:

[0007] (1)若无线网络控制器(RNC)希望根据UE所有上行传输信道和下行传输信道的业务量4B事件来实现信道切换,却由于E-DCH没有业务量上报,始终无法满足E-DCH切换的条件,而无法根据业务量测量来进行E-DCH向低速信道的切换。 [0007] (1) If the radio network controller (RNC) desired to achieve channel switching according to the traffic UE all uplink transport channels and downlink transport channel 4B events, but since the E-DCH no traffic reports, still can not meet the E- DCH handover conditions, and can not be switched to the low E-DCH channel in accordance with traffic volume measurement.

[0008] (2)若RNC仅根据UE上行DCH信道和下行信道的业务量4B事件来实现信道切换, 那么,当数据从承载于E-DCH切换到DCH/FACH/PCH后,很可能由于原E-DCH上承载的实际业务量还比较大,RNC为了保证业务服务质量(QoS),需要再次将切换到DCH/FACH/PCH的数据重新迁移回E-DCH,从而造成了不断乒乓切换的问题,大大降低了信道切换的成功率。 [0008] (2) if the RNC merely is achieved according to the traffic UE uplink DCH channel and the downstream channel 4B event channel switching, then, when the data is switched from the bearer to E-DCH to the DCH / FACH / PCH, probably due to the original the E-DCH actual traffic bearer is still relatively large, RNC in order to ensure quality of service (QoS), you need to switch to a DCH / FACH / PCH again the data re-migrate back to the E-DCH, resulting in problems keep ping-pong handover greatly reduces the success rate of the channel switching. [0009] 从目前协议规定来看,由于未对E-DCH进行测量,导致了在实现E-DCH到低速信道的信道切换时,要么根本不能实现,浪费了无线功率和码资源,影响信道切换的灵活性;要么即使实现了也会大大降低E-DCH向低速信道切换的成功率,从而严重影响了信道切换的稳定性。 [0009] From the current agreement, due not to the E-DCH is measured, resulting in the realization of E-DCH to a low speed channel, channel switching, or simply can not be achieved, wasting wireless power and code resources, effects of the channel switching flexibility; or implements will be greatly reduced even if the success rate of E-DCH channel is switched to a low speed, thereby seriously affecting the stability of the channel switching.

[0036] 图1是本发明方法的流程图,包括以下步骤: [0036] FIG. 1 is a flowchart of a method of the present invention, comprising the steps of:

[0037] 步骤100 :设置E-DCH业务量测量信息。 [0037] Step 100: Set E-DCH traffic measurement information.

[0038] 为支持UE对E-DCH信道的业务量测量,分别在已有业务量测量对象信息、业务量测量事件结果、及业务量测量报告标准配置中的上行传输信道类型信元中,新增E-DCH信道类型;并新增用于区别承载在E-DCH上的各PS业务的E-DCH MAC-d flow identity信元。 [0038] The support of UE traffic measurement of E-DCH channel, respectively, the existing traffic measurement object information, traffic volume measurement event results, and traffic volume measurement uplink transport channel type cell report standard configuration, the new E-DCH by channel type; and a new E-DCH MAC-d flow carried on the difference between the E-DCH each PS service identity information element. 这样,UE能测量E-DCH所对应的逻辑信道上的业务量,即当E-DCH信道上承载的业务量低于某个预设绝对门限值时,上报4B测量报告。 Thus, the UE can measure the traffic on the logical channel corresponding to the E-DCH, i.e. when the traffic bearer channel E-DCH is lower than a predetermined absolute threshold, 4B reports the measurement report.

[0039] 需要说明的是,UE对E-DCH所对应的逻辑信道上的业务量的测量方法,与对RACH、 DCH或USCH的测量方法相同,只是针对不同的信道,属于现有技术,这里不再详述。 [0039] Incidentally, the traffic measurement method for the UE on the E-DCH corresponding to the logical channel, the same method of measuring RACH, DCH or USCH, but for different channels, belonging to the prior art, where not elaborate.

[0040] 步骤101 :网络侧根据用户终端上报的E-DCH业务量测量报告,并在满足预设切换条件时,进行E-DCH到低速信道的切换。 [0040] Step 101: the network side of the E-DCH according to a measurement report reported by the UE traffic, and a preset switching condition is satisfied, for E-DCH to the low speed channel switching.

[0041] 当业务承载在E-DCH上时,本发明方法基于对E-DCH的测量,在E-DCH的业务量测量报告满足预设的切换条件,即业务量测量报告为4B事件测量报告时,进行E-DCH到低速信道如DCH的切换。 [0041] When the traffic carried on the E-DCH, the method of the present invention is based on the measurement of the E-DCH, the traffic volume measurement report E-DCH meets a preset switching condition, i.e. traffic volume measurement report of a measurement report event 4B when, for E-DCH to the DCH, such as switching the low-rate channel.

[0042] 需要说明的是,如果是从E-DCH向如FACH/PCH的低速信道切换,那么,该方法还进一步包括:网络侧判断用户终端上报的与切换相关的信道业务量测量报告,是否同时满足预设切换条件,若满足,则执行E-DCH到低速信道的切换;否则,结束本发明流程。 [0042] Incidentally, if E-DCH switching to the low-rate channel such as FACH / PCH from, then the method further comprises: the network side judges reported by the UE handover-related channel traffic volume measurement report, whether preset switching condition is satisfied, if yes, performing a handover to E-DCH low-rate channel; otherwise, ending the process of the present invention. 相关信道是指UE当前使用的其它所有信道。 Related channel refers to all other channel the UE is currently in use. [0043] 从图1所示的流程可见,本发明方法通过对E-DCH上的业务量的测量,实现了从E-DCH到低速信道的信道切换,降低了由于使用E-DCH对无线功率和码资源的消耗,增强了信道切换的灵活性。 [0043] The process shown in Figure 1 can be seen, the method of the present invention is by measurement of the traffic on the E-DCH, and from the E-DCH to a low speed channel, channel switching, reducing the use of E-DCH radio power and consumption of code resources, enhanced channel switching flexibility.

[0044] 进一步地,预先设置一时间段,并统计该时间段内E-DCH或E-DCH及相关信道上报的4B事件测量报告的次数是否达到预设信道切换门限值,若均达到,才进行E-DCH到低速信道的切换;否则,不进行信道切换。 [0044] Further, a pre-set period of time, and counts the period 4B event E-DCH or E-DCH related channel and a measurement report message number reaches a preset channel switching threshold, if reached, before switching to the E-DCH for low-rate channel; otherwise, channel switching is not performed. 容易看出,本发明这样的处理,很好地解决了乒乓切换的问题,提高了信道切换的成功率,从而进一步加强了信道切换的稳定性。 Readily seen, the present invention is such a process, a good solution to the problem of ping-pong handover and improve the success rate of the channel switching, thereby further enhance the stability of the channel switching.

[0045] 下面结合两个实施例详细描述本发明方法的实现。 [0045] The following implementation of the method of the present invention is described in detail in conjunction with two embodiments.

[0047] 步骤200 :用户终端向网络侧上报E-DCH的4B事件测量报告。 [0047] Step 200: the user terminal reports the measurement report event 4B E-DCH to the network side.

[0048] 步骤201 :网络侧根据预设切换信息判断是否允许从E-DCH向FACH的切换,若允许,则进入步骤202,否则,结束本流程。 [0048] Step 201: the network side in accordance with a preset handover information, whether switching from the E-DCH to the FACH, if allowed, the process proceeds to step 202, otherwise, the process ends.

[0049] 本实施例中,假设在网络侧设置有标识是否允许E-DCH向低速信道切换的切换信息,且该切换信息显示为允许从E-DCH向FACH的切换,进入步骤202。 [0049] In the present embodiment, it is assumed in the embodiment is provided with a network identifier whether to allow the handover information to the handover E-DCH low-rate channel, and the handover information as to allow switching from the FACH E-DCH, proceeds to step 202.
