技术领城 Technical collar city

本发明涉及移动通信技术,更具体的说,本发明涉及一种多栽频 The present invention relates to a mobile communication technology, and more particularly, the present invention relates to a multi-frequency planted

TD-SCDMA移动通信系统中通过Iur接口在漂移无线网络控制器和服务无线网络控制器之间实现终端栽频信息交互的方法, TD-SCDMA mobile communication system via the Iur interface between the drift radio network controller and serving radio network controller implemented method of interactive terminals planted audio information,

髓" marrow"

TD-SCDMA是目前迅速m的笫三代移动通信的三个主要标准之一,这是一种采用了时分双工方式、并在上行方向保证所有终端信号同步到达基站的基于码分多址的移动通信系统,又称为时分-同步码分多址移动通信系统。 TD-SCDMA is one of three main criteria of the current rapid m Zi generation mobile communications, which use a time division duplex mode and to ensure that all uplink signals arrive synchronously at the mobile terminals based on code division multiple access base station communication system, also known as Time division - synchronous Code division Multiple Access mobile communication system. TD-SCDMA系统由第三代合作伙伴计划(3GPP)組织进行标准化,对这一系统的详细描述可参见3GPP的有关标准和技术报告。 TD-SCDMA system standardized by the Third Generation Partnership Project (3GPP) organization, a detailed description of this system can be found in standards and technical reports on the 3GPP.

图1给出了TD-SCDMA系统的网络结构。 Figure 1 shows the network structure of the TD-SCDMA system. 系统由用户设备UE、无线接入网(UTRAN)部分和核心网(CN)部分组成。 System by a user equipment UE, the radio access network (UTRAN) and a core network section (CN) part. 其中无线接入网由l或多个无线网络子系统(RNS)组成,每个RNS包括一个无线网络控制器(RNC)和一个或多个基站(NodeB)组成。 Wherein the radio access network is given by l or more radio network subsystems (RNS), each RNS includes a radio network controller (RNC) and one or more base stations (the NodeB) composition. RNC与核心网之间的接口为Iu接口, NodeB和RNC 之间的接口为Iub"接口,而RNC之间进行通信的接口为Iur接口,上述接口及其接口之间通信的协议均在3GPP相关规范中定义。 Between the RNC and the core network interface Iu interface, the interface between the NodeB and the RNC Iub "interface and the communication interface between the RNC Iur interface, said interface protocol for communication between their associated interfaces of the 3GPP defined in the specification.

在早期的3GPP标准中,每个NodeB被定义为在一个小区仅支持一个栽频, 然而由于单个栽频所能支持的话务量有P艮,不能满足日益增长的移动通信要求。 In earlier 3GPP standard, each NodeB is defined as a plant cell supports only one frequency, however, since a single pilot plant can support a P-Gen traffic, can not meet the increasing requirements of mobile communications. 为此,在TD-SCDMA系统中引入了多栽频的概念,即一个NodeB下的每个小区均支持多个载频,其中一个载频为主载频,而其余的栽频为辅助栽频,这样就可以大大地提高TD-SCDMA系统的容量,其具体技术细节可参看TD-SCDMA的相关行业标准。 For this reason, the introduction of the TD-SCDMA system, the concept of multi-frequency plant, i.e., each cell under a NodeB support multiple carrier frequencies, wherein a main carrier frequency carrier frequency, and the remaining pilot plant auxiliary pilot plant so that it can greatly increase the capacity of TD-SCDMA system, the technical details can be found in the relevant industry TD-SCDMA standard. 然而,由于最初的系统在进行系统设计时没有预见到这种多载频引入后带来的影响,因此在涉及网络实体间的消息交互时,原有的协议以及 However, because the initial system during the system does not foresee affect the introduction of such multi carrier frequency caused by the design, so when the message relates to the interaction between network entities, the original protocol, and

消息交互方法就不能满足多载频TD-SCDMA系统的需求。 Message interaction method can not meet the needs of multi-carrier TD-SCDMA system. 特别是在实际的网络中,很有可能会出现仅支持单载频小区的系统和支持多载频的系统共存的情况, 此时在支持单载频小区的RNC和支持多栽频小区的RNC之间的通信方式就会受到很大约束,在修改协议时必须考虑这种后向兼容性。 Especially in the actual network, it is likely to occur only supports single-carrier system supporting multi-cell and carrier frequency systems coexist, in this case supports a single carrier frequency supports a multi-cell RNC and RNC planted frequency cell communication between will be greatly constrained, backward compatibility must be considered when modifying the protocol.

例如,当终端在切换过程中需要经过Iur接口与网络保持通信连接时, 在这种情况下通过Iur接口连接的两个RNC分别称为服务无线网络控制器(SRNC)和漂移无线网络控制器(DRNC),其中SRNC负责处理终端与核心网(CN)之间通信连接和终端进行信令交互、DRNC控制终端所在小区的无线资源,此时终端切换前后的原小区和目标小区分别由SRNC和DRNC控制。 For example, when the terminal in a handover procedure needs to communicate via an Iur interface remains connected to the network, in this case two RNC is connected via the Iur interface are referred to as serving radio network controller (SRNC) and the drift radio network controller ( DRNC), wherein the SRNC handles the communication between the terminal and the connection terminal and the core network (CN) for signaling interaction, DRNC controlling radio resources of the cell terminal is located, at this time before and after the handover original cell and the target terminal, respectively, by the SRNC and DRNC cell control. 原小区和目标小区可能分别是采用单载频技术的基站或采用多载频技术的基站,而对于终端来说即可能是仅支持单载频技术的终端也可能是能够支持多载频技术的终端。 Original cell and the target cell may be employed are the single carrier base station using the base station frequency technology or multi-frequency technique, i.e. for the terminal and may be a terminal that supports only single-carrier frequency technology may also be capable of supporting the multi-frequency technique terminal. 所谓能够支持多载频技术的终端是指该终端与网络通信时,网络可以在终端所在的小区内的不论主载频还是辅助载频中任意选择一个载频分配资源,而仅支持单载频技术的终端即使在一个采用多栽频技术的小区内,网络也只能为其分配使用主载频上的资源。 The so-called support multi-frequency technique of the terminal means that the terminal and the network communication, the network may regardless of the primary carrier or secondary carrier frequency selected arbitrarily a carrier frequency allocation of resources within a cell terminal is located, but only supports single-carrier frequency terminal technology even in a multi-frequency technique plant cell, the network can only allocate resources for the primary carrier frequency. 这样,在涉及跨越Iur接口进行无线资源的管理与控制时,在多栽频系统情况下,无法在多载频系统中的辅载频执行如图2、 3、 4、 5所示的无线链路建立过程、 无线链路增加过程、同步无线链路重配置过程与物理信道重配置过程,致使资源分配与控制不尽合理,不能充分利用DRNC所管辖小区的辅载频资源, 甚至可能引起主载频资源紧张而辅载频资源得不到利用的极端情况,不能充分发挥多载频系统在容量和通信质量方面的优势。 Thus, when it comes across the Iur interface radio resource management and control, in systems where the multi-frequency plant, not secondary carrier in a multi-carrier system performing frequency wireless link shown in FIG. 2, 3, 4, 5 channel establishment procedure, a radio link addition procedure, the synchronous wireless link reconfiguration procedure the physical channel reconfiguration process, and so that the resource allocation control is not reasonable, the DRNC can not fully utilize resources of the cell under the jurisdiction of the secondary carrier frequency, and may even cause the main the carrier frequency resource constraints and the secondary carrier frequency resources are not utilized in extreme cases, can not take full advantage of multi-carrier system in terms of capacity and quality of communication.

具体实施方式 Detailed ways

本发明的核心在于对于多栽频系统,在涉及跨越Iur接口进行无线资源的管理与控制时,在相应的Iur接口消息中增加用于表示终端的载频编号的信息元素,使得SRNC可以控制DRNC中的终端,并取决于进行无线资源的管理与控制的具体过程而在相应的消息中采用不同的方法来确定是否增加该栽频信息元素。 The core of the present invention is planted for multi-frequency system, when it comes across the Iur interface to manage and control the radio resource information element to increase the carrier frequency number is used to indicate the corresponding terminals Iur interface message, SRNC may control such that the DRNC in the terminal, and depending on the specific process control and management of radio resources and determines whether to increase the frequency information element planted in different ways in the corresponding message.

本技术领域人员知道,保持移动用户与核心网的Iu (UTRAN与CN之间的接口)连接的RNC是SRNC,负责核心网和用户之间的数据传送和Iu接口RANAP (无线接入网络应用部分)信令的转送和接收,负责进行无线资源控制,负责 In the art will appreciate that, holding the mobile subscriber and the core network Iu (interface between UTRAN and CN) connected to the RNC is the SRNC, and for data transfer RANAP Iu interface between the core network and the user (Radio Access Network Application Part ) signaling transfer and reception, is responsible for radio resource control, is responsible for

并执行基本无线资源管理操作,如切换判决、负荷控制、分组数据调度和RAB(无线接入承栽)的参数向空口传输信道参数的转化等。 And perform basic radio resource management operations, such as a handover decision, load control, packet scheduling and the data RAB (Radio Access bearing plant) air interface transmission parameters to the channel conversion parameters and the like. DNRC是SRNC以外的其他RNC,它们控制该移动用户使用的小区,除非该用户使用公共传输信道, DRNC不会进行用户面数据的L2层处理,而只是将Iub接口数据透明的通过Iur 接口的路由传递给SNRC。 DNRC is another RNC other than the SRNC, which control a cell of the mobile users, unless the users use a common transport channel, the DRNC does not perform the L2 layer processing user plane data, but only the Iub interface data transparent over the Iur interface routing passed to SNRC. 当UE因发生切换而进入由DRNC控制的小区的服务范围时,对UE的无线链路控制就分别需要SRNC和DRNC分别来参与完成,并通过信令交互来保证对无线资源管理的一致性。 When the UE enters the handover occurs due to cell service area controlled by a DRNC, the UE RLC will SRNC and DRNC are needed to participated respectively, and to ensure consistency of the radio resource management through signaling interaction.

为了使本技术领域的人员更好地理解本发明方案,下面结合附图和实施方式对本发明作进一步的详细说明。 In order to make those skilled in the art a better understanding of the invention, The present invention will be described in further detail in conjunction with the accompanying drawings and embodiments.

图2示出了本发明方法的具体实施流程,这一流程适合于无线链路建立、无线链路增加和同步无线链路重配置等过程,包括以下步骤: FIG 2 shows a specific embodiment of the method according to the present invention process, this process is suitable to establish a wireless link, a radio link addition and radio link reconfiguration synchronization process and the like, comprising the steps of:

步骤201: DRNC根据接收到的来自SRNC的消息对终端执行无线资源管理过程; Step 201: DRNC performs radio resource management for the terminal based on the message received from the SRNC;

在这一步骤中,DRNC在终端所在的小区内为其分配资源,并根据资源分配的结果进行无线链路控制。 In this step, the DRNC for allocating resources within a cell terminal is located, and a radio link control according to the result of resource allocation. 其中,在无线链路建立时,DRNC必须知道终端是否支持多栽频处理能力,因此在这一步骤之前,SRNC需要向DRNC发送无线链路建立消息,其中,当终端支持多栽频技术时,发送的消息中包括"UE specific requirement indicator"信息元素,否则,所述发送的消息中不包括这一信息元素,以向DRNC指示终端是否支持多栽波处理能力。 Wherein, when the radio link is established, the DRNC must know whether the terminal supports multiple audio processing plant capacity, so before this step, the SRNC sends a radio link setup message needs to the DRNC, wherein, when the terminal supports the multi-frequency technique when planted, message transmitted includes "UE specific requirement indicator" information element, otherwise, the message transmission does not include this information element to indicate to the DRNC whether the terminal supports multi-wave processing plant capacity. 实际上,如果SRNC采用现有技术,既便终端能够支持多栽频,则此SRNC也不能向DRNC指示终端是否支持多栽波,这主要是由于所必须遵循的通信协议的版本的限制,此时,如果DRNC收到该SRNC发送的无线链路建立请求消息,则只能认为终端只支持单栽波而只在主栽波上尝试为该终端分配资源而不管其是否支持多栽波。 In fact, if the SRNC prior art, both terminals will be able to support multi-planted frequency, this can not SRNC to DRNC indicating whether the terminal supports multi-planted wave, which is mainly due to the version of the communication protocol that must be followed limitation, when, if DRNC receive the radio link setup request message sent by SRNC, you can only think that the terminal supports only a single wave planted only try for the terminal on the main cultivated wave allocating resources and whether or not it supports multi-planted waves. 而在无线链路增加时,由于DRNC已经获得了UE是否支持多栽频的信息,因此不必在无线链路增加请求消息中判断是否需要增加"UE specific requirement indicator"信元。 And when the wireless link increases, since the DRNC has received information about whether the UE supports multiple frequency planted, it is not necessary to increase request message determines whether to increase the "UE specific requirement indicator" information element in the radio link.

目前3GPP TS25.423标准定义的无线链路建立过程中的RADIO LINKSETUP REQUEST消息结构如表1所示。 Currently 3GPP TS25.423 standard defines a radio link setup RADIO LINKSETUP REQUEST message structure as shown in Table 1 in the process.

目前的方案只针对单频点系统,因此无法在该消息中指明频点信息。 The current program is only for single-frequency system, it can not specify the frequency information in the message. 在本 In this

发明中,在SRNC发送给DRNC的RADIO LINK SETUP REQUEST消息中增加可选的"UE specific requirement indicator"信元,如表2所示,提供DRNC将无线链路建立在多载频小区的可能性。 In the invention, the DRNC transmits to the RADIO LINK SETUP REQUEST message added optional "UE specific requirement indicator" information element in the SRNC, as shown in Table 2, the DRNC provide radio link is established the possibility of a multi-carrier cell. 其中增加的"UE specific requirement indicator" 信元用于将UE支持多载频的信息指示给DRNC。 Wherein an increase in the "UE specific requirement indicator" information element for the information that the UE supports multiple carrier frequencies indicated to DRNC.

步骤202: DRNC根据无线资源管理过程中对终端分配载频的执行结果确定是否需要在发向SRNC的响应消息中包含载频信息元素。 Step 202: DRNC determined according to the results of the radio resource management process of carrier frequency assigned to the terminal whether to include the carrier frequency information element sent in a response message to the SRNC.

需要说明的是,如果所涉及的过程为无线链路建立过程,在SRNC发给DRNC的无线链路建立消息中,会有存在还是不存在D-RNTI信息元素两种。 Incidentally, if during the process of establishing a radio link is involved, issued DRNC radio link setup message, there will be the presence or D-RNTI information element is not present in the two kinds SRNC. 当存在D-RNTI信息元素时,则DRNC发向SRNC的无线链路建立响应消息中必须携带载频信息元素,本发明的方法则适合于后一种情况。 When the D-RNTI information element is present, the DRNC must send setup response message carries the information carrier element to the SRNC a radio link, the method of the present invention is suitable for the latter case.

当涉及无线链路建立过程和无线链路增加过程时,步骤202又可以进一步分解为以下的具体步骤: When referring to a radio link setup procedure and a radio link addition procedure, step 202 can be further broken down into the following specific steps:

步骤301: DRNC对无线资源管理过程中分配给终端的载频信息进行判断; 步骤302:如果终端被分配的载频信息为小区中的主载频,则执行步骤303, 否则执行步骤304; Step 301: DRNC allocation of radio resource management to the carrier during the determination of the information terminal; Step 302: If the terminal is allocated for the carrier frequency information of the primary carrier frequency in the cell, step 303 is performed, otherwise step 304 is performed;

步骤303: DRNC向SRNC发送响应消息,其中不包括载频信息元素,然后转步步骤305;步骤304: DRNC向SRNC发送响应消息,其中包括载频信息元素,用于指明终端^皮分配的载频编号信息; 步骤305:结束。 Step 303: DRNC transmits to the SRNC a response message, wherein the information element does not include the carrier frequency, then go to step step 305; step 304: DRNC transmits to the SRNC a response message, which includes the carrier frequency information element for indicating a terminal assigned carrier transdermal ^ No frequency information; step 305: end.

其中当涉及无线链路建立过程时,DRNC向SRNC发送的响应消息为无线链路建立响应消息,它需要采用3GPPTS25.423标准定义的无线链路建立过程中的RADIO LINK SETUP REQUEST消息结构,目前的消息结构如表3所示。 Wherein when a radio link establishment procedure relates to the response message sent DRNC to the SRNC radio link establishment response message, it takes for a radio link established standard definition 3GPPTS25.423 RADIO LINK SETUP REQUEST message configuration process, the current The message structure as shown in table 3.

该方案只针对单频点系统,没有对多载频系统如何使用该消息作出进一步的说明,因此不同的设备制造商在实现时存在理解上的歧异,这样开发出来的设备在互连互通时就存在消息不兼容的现象。 This program is only for a single frequency system, no further explanation of how to make a multi-carrier system using the same message, and therefore the understanding divergent different equipment manufacturers exist in implementing such a device it is developed during interconnection there is a message not compatible with the phenomenon.

在本发明中,在DRNC响应的RADIO LINK SETUP RESPONSE消息中增加对已有"UARFCN"信元的注释,如表4及其注释所示,用于保持该信元已有作用的基础上,扩展该消息在多载频情况下的应用。 In the present invention, an increase in the RADIO LINK SETUP RESPONSE message to the DRNC in response to the comments already "UARFCN" cell, as shown in Table 4 and the annotations for maintaining the existing action based on the cell expansion application of the message in the case of multi carrier frequency.

该方案只针对单频点系统,即SRNC会默认为UE的资源在主载频上或者是与无线链路增加过程之前的栽频保持不变,而当DRNC分配的资源发生变化时,这一消息结构就无法对这种情况给予指示。 This program is only for a single frequency system, i.e., SRNC will default to the resources for the UE primary carrier frequency and the plant or before the process of increasing the frequency of the wireless link remains constant, and when the resource allocation is changed DRNC, the The message structure will not be able to give an indication of the situation.

在本发明中,在DRNC响应的RADIO LINK ADDITION RESPONSE消息中增加可选的频点信息信元,如表6所示,只有无线链路增加在多栽频小区的辅栽频上时该信元在消息中出现,而当无线链路增加在单载频小区或增加在多栽频小区的主栽频时该信元不出现。 In the present invention, frequency information adding optional information element in the RADIO LINK ADDITION RESPONSE message in response to the DRNC, as shown in Table 6, only the radio link addition information element in the multi-frequency time-frequency cell auxiliary plant planted It appears in the message, and when the wireless link increases in a single cell or to increase the carrier frequency does not appear in the cell-frequency multi-cell plant cultivars frequency. 频点信息信元用于携带增加的无线链路的频点信息,该信元的详细描述参见3GPPTS25.423 9.2丄66.

当涉及同步无线链路重配置过程时,步骤202又可以进一步分解为以下的具体步骤: When the synchronous radio link reconfiguration procedure involves, step 202 can be further broken down into the following specific steps:

步骤401: DRNC对无线资源管理过程中分配给终端的栽频信息进行判断; 步骤402:如果终端^皮分配的栽频信息与执行无线资源管理过程之前的栽频 Step 401: DRNC radio resource allocated to the terminal management information during pilot plant judgment; Step 402: If the terminal information transdermal ^ pilot plant and distribution plant before performing radio resource management procedures Frequency

信息一致,则执行步骤403,否则执行步骤404; Consistent information, proceed to step 403, otherwise step 404;

步骤403: DRNC向SRNC发送响应消息,其中不包括栽频信息元素,然后 Step 403: DRNC transmits to the SRNC a response message, wherein the information element does not include pilot plant, and

转步骤405; Go to step 405;

步骤404: DRNC向SRNC发送响应消息,其中包括栽频信息元素,用于指明终端被新分配的栽频编号信息; 步骤405:结束。 Step 404: DRNC transmits to the SRNC a response message, wherein the plant comprises a frequency information element for indicating the terminal being planted newly assigned frequency number information; Step 405: End.

其中DRNC向SRNC发送的响应消息为无线链路重配置准备好消息,它需要采用3GPP TS25.423标准定义的同步无线链路重配置过程中的RADIO LINK RECONFIGURATION READY消息结构,目前的消息结构如表7所示。 Wherein the DRNC transmits the response message to the SRNC a radio link reconfiguration ready message, it needs to use a message structure RADIO LINK RECONFIGURATION READY synchronization 3GPP TS25.423 standard defines a radio link reconfiguration process, the current message structure in Table 7. <table>table see original document page 14</column></row> <table>表7 <Table> table see original document page 14 </ column> </ row> <table> Table 7

该方案只针对单频点系统,即SRNC会默认为UE的资源在主载频上或者是与同步无线链路重配置过程之前的栽频保持不变,而当DRNC分配的资源发生变化时,这一消息结构就无法对这种情况给予指示。 This program is only for a single frequency system, i.e., SRNC will default to the resources for the UE before the primary carrier frequency or synchronous radio link reconfiguration procedure planted frequency remains unchanged, and when the resource allocation is changed DRNC, the message structure can not give directions to this situation.

在本发明中,在DRNC响应的RADIO LINK RECONFIGURATION READY 消息中增加可选的载频信息信元,如表8所示,若重配置的无线链路与原来所在栽频不同,该信元出现,若重配置的无线链路与原来所在栽频相同,该信元不出现。 In the present invention, RADIO LINK RECONFIGURATION READY message in response to the DRNC adding optional carrier frequency information cell, as shown in Table 8, if the radio link reconfiguration to the original frequency where the different plant, the cell appears, If the reconfiguration of a radio link with the original plant where the same frequency, the cell does not occur. 频点信息信元用于携带重配置的无线链路的频点信息,该信元的详细描述参见<table>table see original document page 14</column></row> <table>表8 Frequency information for the cell frequency information carrying radio link reconfiguration, see the detailed description of the cell <table> table see original document page 14 </ column> </ row> <table> Table 8

而对于物理信道重配置过程,虽然也是需要在相应的Iur接口消息中增加用于表示终端的栽频编号的信息元素使得SRNC可以获得DRNC中小区的资源使用状况,但具体的执行过程有所不同。 For a physical channel reconfiguration process, although also need to add the appropriate message for the Iur interface represented planted terminal number information element such that the frequency resource use conditions can be obtained the DRNC SRNC cell, but the specific implementation process is different . 因此,这里再给出本发明的一个实施例,针对物理信道重配置过程,具体包括以下步骤: Thus, the invention herein are given a further embodiment, for the physical channel reconfiguration procedure, includes the following steps:

步骤501: DRNC检测到需M改终端的物理信道W:配置时,确定是否需要在发送给SRNC的物理信道重配置请求消息中包含栽频信息元素; Step 501: DRNC detects that a terminal needs to change the M physical channel W: configuration, determine whether reconfiguration request message includes information elements in a physical plant pilot channel transmitted to the SRNC;

这一过程是由DRNC主动发起的,其具体执行的过程包括:首先、DRNC确定终端所在的小区是否支持多栽频; The process is initiated by the DRNC initiative, which includes specific implementation process: first, determine whether the cell DRNC terminal is located supports multi-planted frequency;

其次、如果终端所在的小区支持多载频,则确定在发送给SRNC的物理信道重配置请求消息中包含载频信息元素,否则则确定在发送给SRNC的物理信道重配置请求消息中不包含栽频信息元素。 Secondly, if the cell terminal is located supports a multi-carrier frequency, it is determined that the reconfiguration information element carrier request message includes the transmission to the SRNC physical channel, otherwise it is determined that the transmission to the SRNC a physical channel reconfiguration request message does not contain plant frequency information element.

步骤502: DRNC向SRNC发送物理信道重配置请求消息。 Step 502: DRNC to the SRNC transmits the physical channel reconfiguration request message.

当DRNC向SRNC发送物理信道重配置请求消息时,需要采用3GPP TS25.423标准定义的物理信道重配置过程中的PHYSICAL CHANNEL RECONFIGURATION REQUEST消息结构,目前的消息结构如表9所示。 When the DRNC transmits a physical channel reconfiguration request message to the SRNC, need 3GPP TS25.423 standard defines a physical channel reconfiguration process in the PHYSICAL CHANNEL RECONFIGURATION REQUEST message structure, the current message structure shown in Table 9.

表9 Table 9

该方案只针对单频点系统,即SRNC会默认为DRNC为UE分配的资源在多栽频系统的主栽频或者单栽频系统上,而当DRNC分配的资源所处的栽频发生变化时,这一消息结构就无法对这种情况给予指示。 This program is only for a single frequency system, i.e., SRNC will default resources allocated to the UE in the DRNC cultivars planted multi-frequency system, the single frequency or frequency system planted, and when a change in which the plant resources allocated frequency generation DRNC this message structure will not be able to give an indication of the situation.
