Description

將終端設備重新導向到私人網路的方法、終端設備及基地台 Method for redirecting terminal equipment to private network, terminal equipment and base station

本發明屬於通訊技術領域，特別是關於一種將終端設備重新導向到私人網路的方法及裝置。 The invention belongs to the field of communication technology, and particularly relates to a method and device for redirecting terminal equipment to a private network.

隨著機器型通訊(Machine-Type Communication，MTC)的大量使用，網路需要面臨大量終端存取到網路的問題，同時不同的終端有不同的特性，支持的業務呈現多樣化；例如自動售貨機等的MTC設備可能不需要支援移動性，醫療監測等的MTC設備需要保證資料的即時傳輸，而水錶電錶等的MTC設備則只需要在特定的時間進行小資料傳輸等。為了避免這些MTC設備對現有使用者的服務造成影響，同時對於不同的使用者網路可以為其提供適當的優化服務，營運商可能選擇部署不同類型的核心網路；因此不同的使用者類別的使用者設備(User Equipment，UE)將存取到不同的特定網路中。這個特定的網路稱之為Décor(專用)網路。 With the heavy use of Machine-Type Communication (MTC), the network needs to face the problem of a large number of terminals accessing the network. At the same time, different terminals have different characteristics, and the supported services are diversified; for example, automatic sales MTC devices such as cargo planes may not need to support mobility, MTC devices such as medical monitoring need to ensure the instant transmission of data, and MTC devices such as water meters and electricity meters only need to transmit small data at a specific time. In order to avoid the impact of these MTC devices on the services of existing users, and at the same time can provide appropriate optimization services for different user networks, operators may choose to deploy different types of core networks; User equipment (UE) will access different specific networks. This particular network is called a Décor (dedicated) network.

但是在網路部署時，可能存在前期部署的網路由於沒有進行升級，而不支援Décor網路特性；或者部署網路時營運商只在部分地方部署了Décor網路的情況。對於這種情況UE就只能存取到非Décor網路中，但若當UE移動到了某一支持Décor特性的位置，或者網路檢測到有UE特性的Décor網路的存在，在附著(attach)、追蹤區更新(Tracking Area Update，TAU)或者路由區更新(Routing Area Update，RAU)過程中將會發起如圖 1所示的網路存取伺服器(Network Access Server，NAS)訊息重新導向程序。 However, when the network is deployed, there may be cases where the previously deployed network does not support the Décor network feature because it has not been upgraded; or when the network is deployed, the operator only deployed the Décor network in some places. In this case, the UE can only access the non-Décor network, but if the UE moves to a location that supports Décor characteristics, or the network detects the existence of the Décor network with UE characteristics, it attaches ), Tracking Area Update (TAU) or Routing Area Update (RAU) The network access server (NAS) message redirection process shown in FIG. 1.

步驟1：當第一個新的移動管理實體(Mobility Management Entity，MME)/服務GPRS支援節點(Serving GPRS(General Packet Radio Service，通用分組無線服務技術))Support Node，SGSN)收到UE發起的附著請求(attach request)/TAU請求(TAU request)/RAU請求(RAU request)訊息後，第一個新的MME/SGSN從舊的MME/SGSN或者歸屬家庭用戶伺服器(Home Subscriber Server，HSS)中獲取UE的UE類型資訊。第一個新的MME/SGSN根據UE的UE類型資訊以及配置的資訊確定是否有滿足這一UE需求的Décor網路。 Step 1: When the first new Mobility Management Entity (MME) / Serving GPRS (General Packet Radio Service) Support Node (SGSN) receives the UE-initiated After the attach request / TAU request / RAU request message, the first new MME / SGSN is from the old MME / SGSN or the Home Subscriber Server (HSS) To obtain the UE type information of the UE. The first new MME / SGSN determines whether there is a Décor network that meets the needs of this UE based on the UE type information and configuration information of the UE.

第一個新的MME/SGSN向居民存取網路(Residential Access Network,RAN)發送NAS重新導向請求，請求中攜帶完整的NAS訊息，同時包含第一個新的MME/SGSN為UE選擇的Décor網路的標識資訊。在目前的協定中Décor網路是通過MME群組身份(MME Group ID，MMEGI)(演進的UMTS(Universal Mobile Telecommunications System，通用移動通訊系統)陸地無線存取網路(Evolved UMTS Terrestrial Radio Access Network)，E-UTRAN)或者空的網路資源識別字(Null-NRI(Network Resource Identifier)/SGSN Group ID(UMTS陸地無線存取網路(UMTS Terrestrial Radio Access Network，UTRAN)/GSM(Global System for Mobile Communication，全球移動通訊系統)EDGE(Enhanced Data Rate for GSM Evolution，增強型資料速率GSM演進技術)無線存取網路(GSM EDGE Radio Access Network，GERAN))來進行標識的。 The first new MME / SGSN sends a NAS redirection request to the Residential Access Network (RAN). The request carries the complete NAS message and contains the first new MME / SGSN Décor selected by the UE. Network identification information. In the current agreement, the Décor network is based on the MME Group ID (MMEGI) (Universal Mobile Telecommunications System, Universal Mobile Telecommunications System) terrestrial radio access network (Evolved UMTS Terrestrial Radio Access Network) , E-UTRAN) or Null-NRI (Network Resource Identifier) / SGSN Group ID (UMTS Terrestrial Radio Access Network (UTRAN) / GSM (Global System for Mobile Communication (Global System for Mobile Communications) to identify the EDGE (Enhanced Data Rate for GSM Evolution, Enhanced Data Rate for GSM Evolution) radio access network (GSM EDGE Radio Access Network, GERAN).

步驟2：RAN節點的網路節點選擇功能基於MMEGI或者 Null-NRI/SGSN Group ID為UE選擇一個新的MME/SGSN。 Step 2: The network node selection function of the RAN node is based on MMEGI or The Null-NRI / SGSN Group ID selects a new MME / SGSN for the UE.

步驟3：演進型基地台(evolved Node B，eNB)/無線網路控制器(Radio Network Controller，RNC)向選擇的MME/SGSN發送初始UE訊息(Initial UE message)，其中攜帶UE的NAS請求資訊，以及MMEGI或者Null-NRI/SGSN Group ID資訊。MMEGI或者Null-NRI/SGSN Group ID資訊指示這是一個重新導向的訊息。第二個新的MME/SGSN不能將這一NAS訊息進行再次重新導向。 Step 3: The evolved Node B (eNB) / Radio Network Controller (RNC) sends an Initial UE message to the selected MME / SGSN, which carries the NAS request information of the UE , And MMEGI or Null-NRI / SGSN Group ID information. The MMEGI or Null-NRI / SGSN Group ID information indicates that this is a redirect message. The second new MME / SGSN cannot redirect this NAS message again.

另外如果UE在源小區時不支援Décor網路，而切換後的新小區支援Décor網路，那麼將執行圖2中的步驟： In addition, if the UE does not support the Décor network in the source cell, and the new cell after the handover supports the Décor network, then the steps in Figure 2 will be performed:

步驟4：當切換後的MME決定要將UE重新導向到Décor網路時，MME向UE發起全球唯一臨時標識(Globally Unique Temporary Identity，GUTI)重分配程序，其中攜帶一個沒有廣播的追蹤區標識(Tracking Area Identity，TAI)/路由區標識(Routing Area Identity，RAI)。 Step 4: When the switched MME decides to redirect the UE to the Décor network, the MME initiates a Globally Unique Temporary Identity (GUTI) reassignment procedure to the UE, which carries a tracking area identifier that is not broadcast ( Tracking Area Identity (TAI) / Routing Area Identity (RAI).

步驟5：MME/SGSN釋放RAN側連接，UE移動到閒置狀態。 Step 5: The MME / SGSN releases the RAN side connection, and the UE moves to the idle state.

步驟6：沒有廣播的TAI/RAI觸發UE發起TAU程序。MME/SGSN收到TAU/RAU請求訊息。 Step 6: The TAI / RAI without broadcast triggers the UE to initiate a TAU procedure. The MME / SGSN receives a TAU / RAU request message.

步驟7：MME/SGSN根據圖1所示的程序發起NAS重新導向程序。 Step 7: The MME / SGSN initiates a NAS redirection procedure according to the procedure shown in FIG. 1.

但是相關技術的方案因為考慮到對之前版本終端的相容，不能對UE的行為有影響，所以最後設計的方案比較複雜。特別是切換後發生重新導向，程序更加複雜。相關技術的協議中規定NAS重新導向程序只能發生在UE閒置狀態的TAU/RAU程序中，切換(Hand Over，HO)程序導致 的TAU是不能發起NAS重新導向的。根據相關技術中的程序，UE發生切換後，若離開了原來的追蹤區域清單(Tracking Area(TA)list)，UE需要在切換過程中發起TAU程序。等這一程序結束後，由MME/SGSN發起GUTI重新分配程序，觸發UE再次發起TAU，在這一次的TAU程序中，MME在發起NAS重新導向程序。實現複雜，UE和網路中的互動很多。 However, the scheme of the related technology is more complicated because it considers compatibility with the terminal of the previous version and cannot affect the behavior of the UE. In particular, redirection occurs after switching, and the procedure is more complicated. The related technology agreement stipulates that the NAS redirection procedure can only occur in the TAU / RAU procedure of the UE in an idle state, and the handover (HO) procedure results in TAU cannot initiate NAS redirection. According to the procedures in the related technology, after the UE has switched, if the UE leaves the original Tracking Area (TA) list, the UE needs to initiate a TAU procedure during the handover. After this procedure ends, the MME / SGSN initiates a GUTI re-assignment procedure, which triggers the UE to initiate a TAU again. In this TAU procedure, the MME initiates a NAS redirection procedure. The implementation is complicated, and there are many interactions between the UE and the network.

本發明的目的在於提供一種將終端設備重新導向到私人網路的方法、終端設備及基地台，解決了相關技術中終端設備切換後重新導向時程序複雜，終端設備和網路互動較多，影響重新導向效率且佔用網路頻寬的問題。 The purpose of the present invention is to provide a method for redirecting a terminal device to a private network, a terminal device, and a base station, which solves the complicated procedure when the terminal device is redirected after switching in the related art, and the terminal device interacts with the network more, which affects Redirection issues that consume network bandwidth.
