一种追踪区域更新方法及其设备 One kind of tracking area update method and apparatus

技术领域 FIELD

[0001]本发明涉及无线通信技术领域,尤其涉及一种追踪区域更新方法及其设备。 [0001] The present invention relates to wireless communication technologies, and in particular, to a method and apparatus tracking area update.

背景技术 Background technique

[0002]现有的LTE(Long Term Evolut1n长期演进网络)中,引入了TA(Tracking Area追踪区域)的概念,目前的协议规定每个小区属于且只属于一个TA,在网络规划时,会将网络中的每一个小区进行TA规划,并且在该小区的广播信息中加入TAC(Tracking Area Code,追踪区域编码)信息以及CSG ID(Closed Subscriber Group ID,闭合用户组标识)信息,发送给终端。 [0002] existing LTE (Long Term Evolut1n Long Term Evolution network), the introduction of the concept (Tracking Area tracking area) of the TA, the current agreement provides for each cell belongs to and only belong to a TA, when the network planning, will network each cell by TA plan, and adding TAC in the broadcast information of the cell in (Tracking area Code, tracking area code) information and a CSG ID (closed Subscriber group ID, closed subscriber group identification) information, to the terminal. 与此同时,终端与核心网MME(Mobility Management Entity,移动管理实体)分别存储有针对该终端的TA List(Tracking Area List,追踪区域列表),当有呼叫到达时,MME会按照该列表进行寻呼,从而找到该终端。 At the same time, the terminal and the core network MME (Mobility Management Entity, mobility management entity) are stored seeking for TA List (Tracking Area List, tracking area list) of the terminal, when a call arrives, MME will be carried out in accordance with the list call in order to find the terminal.

[0003]当终端进入新的小区,发现该小区TAC并不在自身所存储的TA List中时,会发起TAU(Tracking Area Update,追踪区域更新),此外,当终端目前所存储的TAC超过一定时间后,也会发起TAU。 [0003] When the terminal enters a new cell, found that the cell TAC not when the TA List itself stored, initiates a TAU (Tracking Area Update, Tracking Area Update), furthermore, when the terminal currently stored TAC than a certain time after, it will initiate TAU.

[0004]由于目前的协议规定每个小区属于且只属于一个TA,当移动终端需要进行TAU时,只能够依据所在小区的唯一的TAC进行TAU,使得TAU的灵活性受到限制。 [0004] Since the current of each cell belonging to a predetermined protocol and only a part of the TA, when the mobile terminal needs TAU, can only be based on a unique TAC TAU camped cell, such that the limited flexibility of TAU.

具体实施方式 Detailed ways

[0019]针对现有小区内追踪区域更新存在的上述问题,本发明实施例在进行网络规划时,在一些小区中配置2个TAC,即这些小区属于两个TAC对应的TA,其中一个TA在另一个TA的覆盖范围之内;当移动终端接收到的小区广播系统信息中包含有2个TAC,则按照区域范围较小TA的TAC进行TAU。 [0019] updates the tracking area for the problems existing within the cell, when performing network planning Example embodiments of the present invention, configured with two TAC in some cells, i.e. cells belonging to the corresponding two TAC TA, where TA is a another within the coverage of the TA; when the mobile terminal receives the cell broadcast system information includes two TAC, TAC is performed in accordance with TAU area smaller range of TA. 由此可见,移动终端能够有更多的TAC进行选择来发起TAU,使得TAU更为灵活,此外,选择区域范围较小TA的TAC进行TAU,缩小寻呼范围,减少了冗余寻呼信令的产生,在节约网络资源的同时也减少了不必要的信令开销。 Thus, the mobile terminal is able to select more TAC initiates TAU, TAU more flexible so that, in addition, the scope of the selection area for a TAC TA TAU smaller, narrow range of paging, paging signaling reduces redundancy generating, saving network resources while also reducing unnecessary signaling overhead.

[0020]下面结合附图对本发明的技术方案进行清楚、完整的描述,显然,所描述的实施例是本发明一部分实施例,而不是全部的实施例。 [0020] DRAWINGS The technical solution of the present invention are clearly and completely described, obviously, the described embodiments are part of the embodiments of the present invention rather than all embodiments. 基于本发明中的实施例,本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例,都属于本发明的保护范围。 Based on the embodiments of the present invention, those of ordinary skill in the art to make all other embodiments without creative effort shall fall within the scope of the present invention.

[0021]本发明实施例中,通信系统在进行TA规划时,为某些特殊小区配置2个TAC,其中一个TAC所对应的TA在另一个TAC所对应的TA范围之内。 When the embodiment, the communication system during planning TA embodiment [0021] of the present invention, configured with two TAC some special cell, within which a corresponding TA TAC TAC corresponding to another TA range. 为区分该2个TAC,本发明实施例中将其中一个称为临时TAC,另一个称为永久TAC,永久TAC对应的TA在临时TAC对应的TA之内。 To distinguish the two TAC, in the embodiments of the invention wherein a temporary called TAC, TAC called permanent another, corresponding to the permanent TAC TAC TA in the TA corresponding to the temporary.

[0022]本领域技术人员应当知晓,所述TAC是唯一的,S卩,不同小区的永久TAC和/或临时TAC都是唯一的,以便核心网根据TAC进行寻呼时,能够唯一确定移动终端所在的小区。 [0022] Those skilled in the art should be aware of the TAC is unique, S Jie, different cells TAC permanent and / or temporary TAC is unique, so that when the core network according TAC paging, the mobile terminal can be uniquely determined district is located.

[0023]所述特殊小区,可以是低功率基站小区,如家庭基站或高速铁路列车中的车载基站(或称车载终端)等,所覆盖的小区,进出这些小区的移动终端有可能只是路过或短暂停留,因而无需移动终端进行TAU。 [0023] The specific cell, the cell may be a low power base station, such as a home base station or a high-speed train in-vehicle station (or car terminal) or the like, covered by cells moving out of these cells may have a terminal or just passing short stay, eliminating the need for mobile terminals TAU. 该特殊小区还可以是节假日中人群活动相对集中的热点区域所在小区。 The special cell may be a cell population where the hot spot area holiday activities in relatively concentrated. 通信系统为这样的小区配置的临时TAC对应的TA可以规划的较大,保证移动终端不需要进行频繁的TAU,而永久TAC对应的TA可以按照区域、终端指纹信息以及业务习惯等,规划的较小,可以包含一个或者几个相邻小区。 Provisional TAC TA corresponding to a communication system configured such cell planning can be large, to ensure that the mobile terminal does not need frequent the TAU, permanently TAC TA can be corrected by the corresponding terminal information and the service fingerprint habits, more planning small, it may comprise one or several adjacent cells.

[0024]基于上述网络规划,图1和图2示出了本发明实施例一提供的移动终端的TAU流程示意图,其中图1为逻辑框图,图2为信令示意图,如图所示,该流程可包括: [0024] Based on the above network planning, FIG. 1 and FIG. 2 shows a schematic flow diagram of the present invention TAU mobile terminal according to a first embodiment, wherein FIG. 1 is a logical block diagram, FIG. 2 is a schematic signaling, as shown, the the process may include:

[0025]步骤1I,移动终端接收到小区广播系统信息后,当从中获取到2个TAC,其中一个是临时TAC(本流程中称为TAC1),另一个是永久TAC(本流程中称为TAC2),并根据获取到的TAC判断自己处在TAC2对应的小区范围内,并在开始驻留或连接到该小区(即在TACl对应的TA(本流程中称为TA1),并从TAC2对应的TA(本流程中称为TA2)之外进入TA2之内或开始驻留)时,启动定时器。 [0025] Step. 1I, the mobile terminal after receiving the cell broadcast system information, which is acquired when the TAC 2, wherein a temporary TAC (this process is called TACl), the other is a permanent TAC (this process is referred TAC2 ), and determines according to the acquired TAC themselves in the cell area corresponding to TAC2, and resides at the beginning of or connected to the cell (i.e., corresponding to TACl TA (TA1 referred to as the present process), and corresponds to the TAC2 when the TA (this process is called TA2) outside the resident to enter or start the TA2), a timer is started.

[0026]本步骤中,移动终端可将其上保存的前次驻留小区的TAC与当前接收到的小区广播系统信息中的TAC进行比较,当定时器超时时,判断自己当前是否仍驻留在所述永久TAC对应的TA小区内。 [0026] In this step, the mobile terminal may save the TAC cell residing thereon previous to the currently received broadcast system information in the cell is compared TAC, when the timer expires, it is determined whether the current still reside their TAC permanent within the cell corresponding to TA. 具体的,在移动终端前次驻留小区配置有临时TAC和永久TAC的情况下,若移动终端前次驻留小区的临时TAC与从小区广播系统信息中获取到的TACl相同,但前次驻留小区的永久TAC与从小区广播系统信息中获取到的TAC2不同,则判断自己开始驻留或连接到在所述永久TAC对应的小区内。 Specifically, the mobile terminal is configured with the previous case where the resident cell temporary and permanent TAC TAC, if the previous temporary TAC acquired from resident cell is a cell broadcast system information to a mobile terminal TACl the same, but in the previous TAC left permanent cell acquired from broadcast system information in the cell to TAC2 different, it is determined that he started or connected to reside permanently within the cell corresponding to TAC. 在移动终端前次驻留小区配置有一个TAC的情况下,若移动终端在该TAC与从小区广播系统信息中获取到的TACl相同,则判断自己开始驻留或连接到在所述永久TAC对应的小区内。 Previous mobile terminal residing in a cell is configured with a case where the TAC, the same as if the mobile terminal acquires the system information from the cell broadcast TACl to the TAC, it is judged that their start or resident in the permanent connection to a corresponding TAC in the cell.

[0027]具体实施时,可在移动终端中存储驻留小区的临时TAC以及驻留小区的永久TAC。 [0027] In specific implementation, the temporary storage TAC may reside in a mobile terminal in a cell and a permanent resident TAC cell. 当移动终端进入到上述TAl和TA2共同覆盖的区域时,会从小区广播系统信息中获取到TACl和TAC2,移动终端将获取到的TACl与存储的前次驻留的TAC比较,如果相同,则将接收到的TAC2与存储的前次驻留的TAC比较,如果不同,或者终端中未存储前次驻留小区的该种类型的TAC,则移动终端判断自己在TAl内,且从TA2之外进入该TA2之内或开始驻留。 When the mobile terminal enters the area of ​​the common coverage TAl and TA2, the cell will be acquired from the broadcast system information and the TACl TAC2, the mobile terminal will compare the acquired TAC TACl the stored previous resides, if the same, then the received and the stored previous TAC2 residing TAC comparison, if a different or previous terminal resident cell is not stored in this type of TAC, the mobile terminal determines its own in TAl, TA2 and from outside or enter the start of the dwell TA2.

[0028]步骤102,当定时器超时时,移动终端判断自己当前是否仍驻留在TA2内,若是,则使用TAC2发起TAU。 [0028] Step 102, when the timer expires, the mobile terminal judges whether it still resides in the current TA2, if yes, initiate the use of TAC2 TAU.

[0029]其中,移动终端使用TAC2所发起的TAU的过程与现有技术类似。 [0029] wherein, the mobile terminal uses TAC2 initiated by the TAU procedure is similar to the prior art. 具体的,移动终端按照TAC2更新自己的TA List,并将该TAC2发送给MME,以使其更新网络侧针对该终端保存的TA List,以便在后续寻呼过程中使用该TAlist进行寻呼。 Specifically, according to the mobile terminal to update their TAC2 TA List, and transmits the TAC2 to the MME, so as to update the network-side stored for the terminal TA List, for use in a subsequent paging TAlist the paging procedure.

[0030] 上述步骤102中,若移动终端判断当前已经离开TA2,则可能有以下几种情况: [0030] In the above step 102, it determines if the mobile terminal has left the current TA2, it may have the following situations:

[0031]情况一:移动终端仅是短时(即在定时器超时时间内)路过或停留在TA2内然后移出TA2,但仍在TAl覆盖范围内时,移动终端此时接收到的小区广播信息中仅包含一个TAC,且与TACl值相同,因此移动终端不会发起TAU。 [0031] Case 1: The mobile terminal only short cell broadcast information (i.e., the timer timeout time) or remains in a pass out of TA2 and TA2, TAl but still within the coverage area, the mobile terminal received at this time contains only one the TAC, and TACl same value, the mobile terminal does not initiate a TAU.

[0032]情况二:移动终端仅是短时(即在定时器超时时间内)路过或停留在TA2内然后移出TA2,但进入TA I覆盖范围内的另一个TA (如TA3),该TA3所覆盖的小区配置有2个TAC,表明移动终端进入到TAl区域内的另一个配置有2个TAC的特殊小区,此种情况下,移动终端会按照本发明实施例提供的方式进行处理。 [0032] Case 2: the mobile terminal is only a short time (i.e., the timer timeout time) or remains in a pass out of TA2 and TA2, but the I into another TA TA inner coverage (e.g. TA3), which is TA3 cell covered arranged two TAC, indicate that the mobile terminal enters another region TAl arranged in two TAC of special cells, in this case, the mobile terminal provided by the embodiment will be treated in accordance with the embodiment of the present invention.

[0033]情况三:移动终端仅是短时(即在定时器超时时间内)路过或停留在TA2内然后移出TA2,并且移出TAl,此时,移动终端接收到的TAC会发生变化,移动终端将按照现有方式发起TAU ο [0033] The three cases: the mobile terminal is only a short time (i.e., the timer timeout time) or remains in a pass out of TA2 and TA2, TAl and removed, at this time, the mobile terminal receives the TAC will change, the mobile terminal We will initiate a TAU ο back to the way

[0034]优选的,定时器的时长由网络侧配置,定时器时长参数作为小区系统信息广播,移动终端根据该定时器时长参数设定定时器时长。 [0034] Preferably, the duration of the timer is configured by the network side, as long cell parameter information broadcast system, the mobile terminal according to the duration parameter setting length when the timer Timer timer. 这样,网络侧可根据具体规划或业务需要等情况,灵活调整定时器时长参数,并配置到相应基站上。 Thus, the network side according to the situation specific programs or other business needs, flexibility to adjust the timer when the size parameter, and arranged to the respective base station. 当然,定时器时长参数也可以预先配置在移动终端中,如通过半静态方式由网络侧配置或在移动终端中预先预置,这样就无需在小区系统信息中携带该定时器时长参数,可以节省网络资源开销。 Of course, when the timer duration parameter may be pre-configured in the mobile terminal, such as semi-statically configured by the network side or preset in advance in the mobile terminal, so that the parameters need to carry long timer cell system information, can be saved network resource overhead.

[0035]通常,小区广播系统信息中还携带有CSG ID信息,针对这种情况,本发明提供的实施例二中,移动终端根据从小区广播系统信息中获取到的CSG ID信息判断本移动终端是否为该CSG成员,并在判断为是的情况下,使用TAC2发起TAU;若判断本移动终端不是该CSG成员,则不会使用TAC2发起TAU。 [0035] Generally, a cell broadcast system information further carries the CSG ID, for this situation, the present invention provides the second embodiment of the mobile terminal determines that the mobile terminal based on the acquired broadcast system information from a cell to the CSG ID for the case where the CSG member if, and if yes, the use of TAC2 initiate the TAU; if it is determined that the mobile terminal is not a member of the CSG is not used to initiate TAC2 TAU.

[0036]本实施例中将CSG成员作为发起TAU的判断条件,排除了非CSG成员发起TAU的情况,能够避免不必要的TAU过程,节约网络资源。 [0036] CSG member in the present embodiment examples of the determination condition initiates a TAU, excluding the case where non-CSG members initiates a TAU, it is possible to avoid unnecessary TAU procedure, save network resources.

[0037]在本发明的实施例三中,可将上述实施例一和实施例二结合使用。 [0037] In the three embodiments of the present invention, the above-described first embodiment and second embodiment in combination. 具体的,移动终端从接收到的小区广播系统信息中获取到TACl和TAC2后,判断自己处在TAl内,并从TA2之外进入TA2之内时,启动定时器。 Specifically, after the mobile terminal obtains from the received cell information to the broadcast system and TAC2 TACl, their determination is within TAl, TA2 and enters the inside of the timer is started from outside TA2. 当定时器超时时,移动终端判断自己当前仍驻留在TA2内,且根据从小区广播系统信息中获取到的CSG ID信息判断本移动终端为该CSG成员时,使用TAC2 发起TAU。 When the timer expires, the UE determines the current still reside in their TA2, and it is determined that the mobile terminal when the present CSG member, using TAC2 initiates a TAU based on the acquired broadcast system information from a cell to the CSG ID.

[0038] 本发明实施例可适用于以下场景: [0038] Example embodiments of the present invention is applicable to the following scenarios:

[0039] 在家庭基站场景中,可为家庭基站覆盖的小区配置2个TAC,即该家庭基站所覆盖的小区属于2个TA,其中一个为家庭基站所覆盖区域,另一个是宏基站所覆盖的区域。 [0039] In the home base station scenario, the home base station may cover a cell configuration 2 the TAC, i.e., the home base station belongs to a cell covered by the TA 2, wherein one of the areas covered by the home base station, the other covered with a macro base station Area. 当移动终端进入家庭基站覆盖区域时,并不立即进行TAU,当移动终端在该家庭基站区域内驻留超过一定时长时,才按照家庭基站区域对应的TAC发起TAU,从而使MME更新该移动终端TAList,后续使用更新后的TA List进行寻呼。 When the mobile terminal enters the coverage area of ​​the home base station, TAU is not carried out immediately, when the mobile terminal exceeds a certain length of time resides in the home base station area, only an area corresponding to the home base station according TAC TAU initiated, so that the mobile terminal updates the MME TAList, subsequent use TA List updated paging.

[0040]在节假日场景中,可为热点区域的小区配置2个TAC,即该区域所覆盖的小区属于2个TA,其中一个为该区域所覆盖区域,另包含该区域的更大范围的区域。 [0040] In the holiday scene, the cell may be configured to the TAC hotspot zone 2, i.e., the area covered by cells belonging to the TA 2, wherein the coverage area for a region, the other region including the region of the larger . 当移动终端进入该热点区域时,并不立即进行TAU,当移动终端在该热点区域内驻留超过一定时长时,才按照该热点区域对应的TAC发起TAU,从而使MME更新该移动终端TA Li st,后续使用更新后的TAList进行寻呼。 When the mobile terminal enters the hot spot area, TAU is not carried out immediately, when the mobile terminal exceeds a certain length of time residing within the hot spot area, only a corresponding region in accordance with the hot spot to initiate TAU TAC, such that the MME to update the mobile terminal TA Li st, subsequent use TAList updated paging.

[0041]在家庭基站场景和节假日场景中应用本实施例,移动终端长期驻留在家庭基站区域或者热点区域内时,MME可仅在该区域范围内进行寻呼时,即寻呼区域缩小为家庭基站区域或者热点区域,从而与现有技术在较大范围内寻呼移动终端相比,减少了寻呼资源开销,提高了寻呼效率。 When [0041] the home base station of the present application and holiday scene Scene embodiment, the mobile terminal residing in the home base station long area or hot spot area, the MME may be paged only within the region, i.e. the paging area is reduced to the home base station area or hot spot area, as compared with the prior art paging mobile terminals in a wide range, reduce the overhead of paging resources, improving the efficiency of paging.

[0042]在高铁场景中,可为列车中的车载终端所覆盖的区域配置2个TAC,一个对应于该车载终端所覆盖区域,另一个对应于列车停靠站所在的较大范围的区域。 [0042] In the high-speed scenario, may be configured to train in-vehicle terminal region covered by the TAC 2, corresponding to the area covered by the vehicle-mounted terminal, the other region corresponding to the wide range in the train stops located. 当移动终端进入车厢后,并不立即进行TAU,当移动终端驻留在车厢内超过一定时长时,才按照车厢内的TAC发起TAU,使MME更新该移动终端TAList,后续使用更新的后TA List进行寻呼,其中,定时器时长参数根据列车在站台停靠的时间来确定,如定时器时长参数等于列车在站台停靠时间。 When the mobile terminal enters the cabin, the TAU is not carried out immediately, when the mobile terminal residing in a certain period exceeds the cabin, only in accordance with the TAC in the compartment to initiate the TAU, so MME updating a TA list of the mobile terminal, the subsequent use of the updated TA List paging, wherein the parameter determining the timer length according to the train stops at the platform of time, such as long-time parameter is equal to the train stops at the platform when the timer.

[0043]在高铁场景中应用本实施例TA更新方法,针对在站台接送亲友的情形,即移动终端仅仅在车厢内做短暂停留,在列车开车之前就会离开车厢,采用本实施例可仅对开车时仍驻留在车厢内的移动终端按照车厢内的TAC发起TAU,减少了不必要的TAU,节约了网络资源。 [0043] Application of high-speed scene TA update procedure of the present embodiment, for friends and relatives in the case of pick-up station, i.e. the mobile terminal only for a short stay in the compartment, the train will leave the vehicle before driving, with the present embodiment may only mobile terminal while driving still reside in the compartment in accordance with the TAC in the cabin initiate TAU, reducing unnecessary TAU, saving network resources.

[0044]通过以上流程可以看出,通信系统在进行TA规划时,为某些特殊小区配置2个TAC,从而使该小区属于2个范围大小不同的TA,当移动终端进入小范围TA但仍在该大范围TA内时,并不立即发起TAU,而是启动定时器,在定时器超时后判断自己仍在该小范围TA内时才发起TAU,从而避免进行不必要的TAU,进而节省了资源开销;另一方面,移动终端在小范围TA内发起TAU时使用小范围TA所对应的TAC,从而使网络侧根据该小范围的TAC更新该终端的TA List,进而在寻呼该终端时可在较小范围内寻呼,提高了寻呼效率,并减少了寻呼时延。 [0044] As can be seen by the above process, the communication system during planning TA arranged two TAC for certain special cells so that the cells belong to two different size ranges TA, when the mobile terminal enters a small but still TA within this large range TA, did not immediately initiate TAU, but starts a timer, the timer expires after the judge himself is still small when initiated within the TAU TA, thereby eliminating unnecessary TAU, thereby saving on the other hand, when the mobile terminal initiates a TAU using a small area in a small area TA corresponding TAC TA, so that the network side of the small-sized TAC update the terminal TA List, and further to the paging terminal; resource overhead may page a lesser extent, to improve the efficiency of paging, paging and reduce delay.

[0045]基于相同的技术构思,本发明实施例四还提供了一种移动终端,包括:获取模块,用于接收小区广播的系统信息,并从中获取TAC;更新模块,用于当获取模块获取到临时TAC和永久TAC时,使用永久TAC发起TAU;其中,临时TAC和永久TAC是通信系统为小区配置的,7欠久TAC对应的TA在临时TAC对应的TA之内。 [0045] Based on the same technical concept, according to a fourth embodiment of the present invention further provides a mobile terminal, comprising: obtaining means for receiving system information broadcast by the cell, and obtain the TAC; updating module, configured to, when acquiring module acquires the temporary and permanent TAC TAC, TAC permanent initiate the TAU; wherein, temporary and permanent TAC TAC communication system is configured for a cell, within 7 years under TAC TAC corresponding TA in the TA corresponding to the temporary.

[0046]优选的,本发明实施例五还提供了一种移动终端,如图3所示,该移动终端300可包括: [0046] Preferably, according to the fifth embodiment of the present invention further provides a mobile terminal, shown in Figure 3, the mobile terminal 300 may comprise:

[0047]获取模块301,用于接收小区广播的系统信息并从中获取TAC; [0047] The acquisition module 301, a system for receiving information broadcast by the cell and obtain the TAC;
