Description
本發明有關用於媒體獨立遞交(MIH)之通信資訊,且尤其係有關一種支援行動終端的遞交。The present invention relates to communication information for media independent delivery (MIH), and more particularly to the delivery of a support mobile terminal.
以下大體上將說明依據先前技術之寬頻無線存取系統。與習知2G及3G行動通信系統不同的係,用於寬頻無線存取系統之國際標準化的IEEE 802.16e系統係在進展中,其未設有一分層結構,該結構係用於一本地位置暫存器(HLR)、一訪客位置暫存器(VLR)、一行動交換中心(MSC)、一基地台控制器(BAS)、一無線電網路控制器(RNC)及類似者。然而,IEEE 802.16e系統包括一行動用戶台(MSS)作為行動終端、一基地台(BS)及一作為鑑別管理伺服器之鑑定服務授權(ASA)。此外,一共同實體層(PHY)及一媒體存取控制(MAC)層係在基地台及行動用戶台間界定。Broadband wireless access systems in accordance with the prior art will generally be described below. Unlike the conventional 2G and 3G mobile communication systems, the IEEE 802.16e system for international standardization of broadband wireless access systems is in progress, and it does not have a hierarchical structure, which is used for a local location. A register (HLR), a visitor location register (VLR), a mobile switching center (MSC), a base station controller (BAS), a radio network controller (RNC), and the like. However, the IEEE 802.16e system includes a mobile subscriber station (MSS) as a mobile terminal, a base station (BS), and an authentication service authorization (ASA) as an authentication management server. In addition, a common physical layer (PHY) and a media access control (MAC) layer are defined between the base station and the mobile subscriber station.
第1圖係一用於寬頻無線存取系統中的正交分頻多重存取(OFDMA)實體層之訊框結構的圖式。參考第1圖,一下行鏈路子訊框以一用於在實體層中同步化及等化之前文開始。接著,該前文係界定分配予下行鏈路及上行鏈路之叢發(burst)的位置及用法一之廣播格式化下行鏈路映射(DL-MAP)訊息及一訊框控制標頭(FCH)。一上行鏈路映射(UL-MAP)訊息跟著DL-MAP和FCH以界定整個訊框之結構。Figure 1 is a diagram of a frame structure for an orthogonal frequency division multiple access (OFDMA) physical layer in a broadband radio access system. Referring to Figure 1, the downlink subframe is started with a syntax for synchronization and equalization in the physical layer. Then, the foregoing defines the location of the burst allocated to the downlink and uplink, and the usage of the broadcast formatted downlink mapping (DL-MAP) message and the frame control header (FCH). . An uplink mapping (UL-MAP) message follows the DL-MAP and FCH to define the structure of the entire frame.
DL-MAL及UL-MAP訊息的實例分別在表1及表2中。Examples of DL-MAL and UL-MAP messages are shown in Tables 1 and 2, respectively.
在叢發模式實體層中,DL-MAP訊息界定分配予一下行鏈路間隔之叢發的用法,且UL-MAP界定分配予一上行鏈路間隔之叢發的用法。對於配置DL-MAP訊息之資訊元素(如表3中顯示),一下行鏈路訊務間隔係在使用者端藉由一下行鏈路間隔使用碼(DIUC)、一連接識別符(CID)及叢發位置資訊(如次通道偏移、符號偏移、次通道號碼及符號號碼)辨識。對於配置UL-MAP訊息的資訊元素(如表4中顯示),用法係藉由每一連接識別符(CID)一上行鏈路間隔使用碼(UIUC)決定。一對應間隔之位置係藉由持續時間調節。在此情況下,係依據一用於UL-MAP中之UIUC值決定每一間隔一用法。各間隔在離由UL-MAP IE調節之一先前資訊元素(IE)起點一些距離的一點開始。In the burst mode entity layer, the DL-MAP message defines the usage of the bursts allocated to the downlink interval, and the UL-MAP defines the usage of the bursts allocated to an uplink interval. For the information element of the DL-MAP message (as shown in Table 3), the downlink traffic interval is at the user end by the downlink interval usage code (DIUC), a connection identifier (CID), and Identification of burst location information (such as secondary channel offset, symbol offset, secondary channel number, and symbol number). For information elements that configure UL-MAP messages (as shown in Table 4), usage is determined by each Connection Identifier (CID) - Uplink Interval Usage Code (UIUC). The position of a corresponding interval is adjusted by duration. In this case, each interval is used in accordance with a UIUC value used in the UL-MAP. Each interval begins at a point some distance from the start of one of the previous information elements (IE) adjusted by the UL-MAP IE.
DL-MAP前之訊框控制標頭(FCH)係一指示編碼資訊及一DL-MAP長度之標頭。表5顯示FCH之訊框結構。The frame control header (FCH) before the DL-MAP is a header indicating the coded information and a DL-MAP length. Table 5 shows the frame structure of the FCH.
表6顯示一相鄰者廣告(MOB_NBR-ADV)訊息之實例成為一相鄰基地台之廣播訊息。一基地台週期性地經由MOB_NBR-ADV訊息廣播關於相鄰基地台的資訊。一行動用戶台接收該訊息且參考其用於掃描及遞交。Table 6 shows an example of a neighbor advertisement (MOB_NBR-ADV) message as a broadcast message of a neighboring base station. A base station periodically broadcasts information about neighboring base stations via MOB_NBR-ADV messages. A mobile subscriber station receives the message and references it for scanning and delivery.
表7及表8分別係一基本能力請求(SBC-REQ)訊息及一基本能力回應(SBC-RSP)訊息之具體實施例。已接收DL-MAP及UL-MAP之行動用戶台針對一網路存取程序執行測距,且傳輸一SBC-REQ訊息至基地台,以起始一對於基本能力之協商。為回應該協商,基地台發送一有關符合其效能之部分的SBC-RSP訊息。Tables 7 and 8 are specific embodiments of a basic capability request (SBC-REQ) message and a basic capability response (SBC-RSP) message, respectively. The mobile subscriber station that has received the DL-MAP and UL-MAP performs ranging for a network access procedure and transmits an SBC-REQ message to the base station to initiate a negotiation for basic capabilities. In order to negotiate, the base station sends a SBC-RSP message about the part that matches its performance.
一旦完成針對基本能力之協商,行動用戶台經由一註冊請求(MOB-REG-REQ)訊息及一註冊回應(MOB-REG-RSP)訊息執行一註冊程序。表9及表10分別顯示MOB-REG-REQ及MOB-REG-RSP訊息的實例。Once the negotiation for the basic capabilities is completed, the mobile subscriber station performs a registration procedure via a registration request (MOB-REG-REQ) message and a registration response (MOB-REG-RSP) message. Tables 9 and 10 show examples of MOB-REG-REQ and MOB-REG-RSP messages, respectively.
現將解釋媒體獨立遞交(MIH)技術。IEEE 802.21系統(針對異質間網路媒體獨立遞交之國際標準化進行)之目的,係要藉由在異質網路間提供無縫遞交及服務連續性,以增強行動終端裝置之使用者便利。一MIH功能、事件觸發、命令服務及資訊服務(IS)係界定為IEEE 802.21系統之基本需求。Media Independent Submission (MIH) technology will now be explained. The purpose of the IEEE 802.21 system (for international standardization of heterogeneous network media independent delivery) is to enhance the user convenience of mobile terminal devices by providing seamless delivery and service continuity between heterogeneous networks. An MIH function, event triggering, command service, and information service (IS) are defined as the basic requirements of the IEEE 802.21 system.
一行動用戶台係一支援至少一介面類型的多節點,其中一介面可在各種類型中實施。可能之介面類型包括一諸如IEEE 802.3為基之導線類型介面、基於IEEE 802.XX之(包括IEEE 802.11、IEEE 802.15、IEEE 802.16或類似者)無線介面類型、及由諸如3GPP及3GPP2之胞狀標準化組織所界定的介面。A mobile subscriber station supports multiple nodes of at least one interface type, one of which can be implemented in various types. Possible interface types include a wire type interface such as IEEE 802.3, a wireless interface type based on IEEE 802.XX (including IEEE 802.11, IEEE 802.15, IEEE 802.16 or the like), and cell standardization such as 3GPP and 3GPP2. The interface defined by the organization.
第2圖係一多模式行動用戶台的範例性圖式。參考第2圖,一多模式行動用戶台包括每一模一實體層(PHY),且每一模一媒體存取控制(MAC)層。此外,一MIH層置於IP層下。Figure 2 is an exemplary diagram of a multi-mode mobile subscriber station. Referring to FIG. 2, a multi-mode mobile subscriber station includes each Modular Physical Layer (PHY) and each Modular Media Access Control (MAC) layer. In addition, an MIH layer is placed under the IP layer.
媒體獨立遞交(MIH)係界定在IEEE 802系列介面等之間,或在一IEEE 802系列介面及一非IEEE 802系列介面(例如3GPP或3GPP2介面)間。同樣地,一例如行動IP之上層的行動性支援協定及對話初始協定(SIP)被支援用於無縫遞交服務。Media Independent Submission (MIH) is defined between IEEE 802 series interfaces and the like, or between an IEEE 802 series interface and a non-IEEE 802 series interface (eg, 3GPP or 3GPP2 interface). Similarly, an mobility support agreement and a SIP Initial Agreement (SIP), such as the upper layer of the Mobile IP, are supported for seamless delivery of services.
以下解釋在初始化一寬頻無線存取系統中之網路註冊程序。第3圖係在寬頻無線存取系統中之行動台初始化程序的流程圖。參考第3圖,一旦打開行動用戶台的開關,行動用戶台搜尋一下行鏈路通道且經由一DL-MAP及一UL-MAP獲得與一基地台之上行鏈路/下行鏈路同步化(1)。行動用戶台經由RNG-REQ及RNG-RSP訊息藉著與基地台的測距來調整上行鏈路傳輸參數,且基地台分配一基本管理連接識別符(CID)及主要管理CID至行動用戶台(2)。行動用戶台接著經由SBC-REQ及SBC-RSP訊息與基地台協商一基本能力(3)。之後,係在行動用戶台上實施授權(4)。接著行動用戶台經由REG-REQ及REG-RSP訊息施行一註冊程序至基地台,其中基地台將一次要管理CID分配予由一網際網路協定(IP)管理的行動用戶台(5)。一旦產生IP連接(6),則設定一目前日期及時間(7)。接著係自一簡易檔案傳送協定(TFTP)伺服器下載該行動用戶台之組態檔案(8),且產生一用於已預備服務之連接(9)。The following describes the network registration procedure in initializing a broadband wireless access system. Figure 3 is a flow chart of the mobile station initialization procedure in a broadband wireless access system. Referring to FIG. 3, once the switch of the mobile subscriber station is turned on, the mobile subscriber station searches for the downlink channel and obtains uplink/downlink synchronization with a base station via a DL-MAP and a UL-MAP (1). ). The mobile subscriber station adjusts the uplink transmission parameters by RNG-REQ and RNG-RSP messages by ranging with the base station, and the base station allocates a basic management connection identifier (CID) and a primary management CID to the mobile subscriber station ( 2). The mobile subscriber station then negotiates a basic capability (3) with the base station via the SBC-REQ and SBC-RSP messages. After that, the authorization is implemented on the mobile subscriber station (4). The mobile subscriber station then performs a registration procedure to the base station via the REG-REQ and REG-RSP messages, wherein the base station will assign the management CID to the mobile subscriber station (5) managed by an Internet Protocol (IP). Once the IP connection (6) is generated, a current date and time (7) is set. The configuration file (8) of the mobile subscriber station is then downloaded from a Simple File Transfer Protocol (TFTP) server and a connection (9) for the prepared service is generated.
在媒體獨立遞交(MIH)中,一MIH功能係置於一IP層下且實現一遞交處置過程,其使用來自一第二層(層2)之一觸發事件及一輸入值,諸如其他網路及類似者的資訊。MIH功能可包括基於可能影響遞交過程之使用者策略及組態的輸入值。通用介面係在MIH功能及一第三層(層3)實體間界定,諸如一行動網際網路協定(行動IP)及一對話初始協定(SIP)。此等介面提供有關一第一層(實體層)、一第二層(層2;MAC層)及行動性管理之資訊。MIH在事件及資訊服務協助下取得有關下層及一網路的資訊。因此,應將MIH功能置於更高層以監視及控制行動用戶台內之其他鏈路的狀態。第4圖係功能實體的圖表及一包括MIH功能及網路之終端的傳送協定,其中點線指示一原語、一事件觸發及類似者。In Media Independent Submission (MIH), an MIH function is placed under an IP layer and implements a delivery process that uses one of the triggering events and an input value from a second layer (layer 2), such as other networks. And similar information. MIH functions may include input values based on user policies and configurations that may affect the delivery process. The generic interface is defined between the MIH function and a Layer 3 (Layer 3) entity, such as a Mobile Internet Protocol (Mobile IP) and a Session Initiative (SIP). These interfaces provide information about a first layer (physical layer), a second layer (layer 2; MAC layer), and mobility management. MIH has access to information on the underlying and one network with the assistance of the event and information services. Therefore, the MIH function should be placed at a higher level to monitor and control the status of other links within the mobile subscriber station. Figure 4 is a diagram of a functional entity and a transport protocol including a MIH function and a terminal of the network, wherein the dotted line indicates a primitive, an event trigger, and the like.
以下解釋一用於在異質網路間遞交之事件觸發。對於快速遞交,一網路層需要使用來自一鏈路層之資訊以儘早重建一連接。一鏈路層事件協助估計一使用者之運動及可協助行動用戶台及網路提前準備遞交。一用於遞交的觸發可用實體層(PHY)及媒體存取控制層(MAC)開始。此觸發之起源可為一本地堆疊或或遠端堆疊。第5圖係一觸發模型的圖式。The following explains an event trigger for submitting between heterogeneous networks. For fast delivery, a network layer needs to use information from a link layer to re-establish a connection as early as possible. A link layer event assists in estimating the motion of a user and assists the mobile subscriber station and the network in preparing for delivery. A trigger for delivery can begin with a physical layer (PHY) and a medium access control layer (MAC). The origin of this trigger can be a local stack or a remote stack. Figure 5 is a diagram of a trigger model.
一事件觸發提供目前信號的狀態、另一網路之狀態改變及已估計的改變。該事件觸發亦提供有關在實體層及媒體存取控制層間之改變及一特定網路的屬性變化的資訊。可將事件類型分類如下:(1)PHY層事件;(2)MAC層事件;(3)管理事件;(4)L3事件;及(5)應用事件。An event trigger provides the status of the current signal, the state change of the other network, and the estimated change. The event trigger also provides information about changes between the physical layer and the media access control layer and changes in attributes of a particular network. Event types can be classified as follows: (1) PHY layer events; (2) MAC layer events; (3) management events; (4) L3 events; and (5) application events.
現將解釋基本觸發事件。當一層2(L2)連接係在一特定鏈路介面間建立及當層3(L3)訊包可從一更高層傳送時,一「Link_Up」觸發事件會發生。在此情況下,係決定所有配置該鏈路之L2組態已完成。事件起源係一本地MAC及一遠端MAC。參數係顯示在表11中。The basic triggering event will now be explained. A "Link_Up" trigger event occurs when a layer 2 (L2) connection is established between a particular link interface and when a layer 3 (L3) message can be transmitted from a higher layer. In this case, it is determined that all L2 configurations configuring the link have been completed. The origin of the event is a local MAC and a remote MAC. The parameter is shown in Table 11.
當一L2連接係在一特定鏈路介面上釋放且當不再需要傳送L3訊包時,一「Link_Down」觸發事件會發生。一事件起源係一本地MAC。參數係顯示在表12中。A "Link_Down" trigger event occurs when an L2 connection is released on a particular link interface and when it is no longer necessary to transmit an L3 packet. The origin of an event is a local MAC. The parameter is shown in Table 12.
[表12]
當估計一L2連接係將於特定時間內下行鏈結時,一「Link Going Down」觸發事件會發生。「Link Going Down」觸發事件可為一用於初始化遞交程序之信號。事件起源係一本地MAC及一遠端MAC。參數係顯示在表13中。A "Link Going Down" trigger event occurs when it is estimated that an L2 connection will be downlinked within a specified time. The "Link Going Down" trigger event can be a signal used to initialize the delivery process. The origin of the event is a local MAC and a remote MAC. The parameter numbers are shown in Table 13.
當估計一L2連接係將於特定時間內上行鏈結時,一「Link Going Up」觸發事件會發生。「Link Going Up」觸發事件係用於當欲初始化之網路需要一段長時間時。事件起源係一本地MAC及一遠端MAC。參數係顯示在表14中。A "Link Going Up" trigger event occurs when it is estimated that an L2 connection will be uplinked within a specified time. The "Link Going Up" trigger event is used when the network to be initialized takes a long time. The origin of the event is a local MAC and a remote MAC. The parameter numbers are shown in Table 14.
一「Link_Available」觸發事件指示一新特定鏈路係可用或有空。再者,該「Link_Available」事件指示一新基地台或存取點(AP)或附接點(POA)可提供品質比目前由一行動用戶台存取之基地台或AP或POA更好之鏈路的可能性。事件起源係一本地MAC及一遠端MAC。參數係顯示在表15中。A "Link_Available" trigger event indicates that a new specific link is available or available. Furthermore, the "Link_Available" event indicates that a new base station or access point (AP) or point of attachment (POA) can provide a better quality than a base station or AP or POA currently accessed by a mobile subscriber station. The possibility of the road. The origin of the event is a local MAC and a remote MAC. The parameter numbers are shown in Table 15.
現將解釋一用於異質間網路遞交的資訊服務。媒體獨立資訊服務(MIIS)在一階層異質網路上提供一類似訊框網路,以有利於搜尋及選擇各種類之出現網路。即,媒體獨立資訊服務(MIIS)提供關於一需要搜尋之網路及選擇一網路且應可從任何種類之網路存取的詳細資訊。媒體獨立資訊服務(MIIS)應包括以下資訊元素,諸如鏈路存取參數、保全機制、相鄰者映射、位置、供應者及其他存取資訊、鏈路之費用及類似者。An information service for the submission of heterogeneous networks will now be explained. The Media Independent Information Service (MIIS) provides a similar frame network on a heterogeneous network to facilitate the search and selection of various types of emerging networks. That is, Media Independent Information Services (MIIS) provides detailed information about a network that needs to be searched and a network that should be accessible from any type of network. The Media Independent Information Service (MIIS) should include the following information elements such as link access parameters, security mechanisms, neighbor mapping, location, provider and other access information, link costs, and the like.
第6圖係根據相關技術用於獲得資訊服務之程序的流程圖。參考第6圖,一行動用戶台(MS)之MIH傳送一MIH_info.request訊息至其MAC,以請求一資訊服務(S610)。行動用戶台之MAC接著傳送一資訊請求訊框至一基地台(BS)(S620)。該基地台之一MAC經由MIH_info.indication訊息將資訊請求自行動用戶台傳遞至其MIH(S630)。基地台之MIH接著經由一MIH_info.response訊息將一保留媒體獨立資訊服務傳遞至MAC層(S640)。此使得基地台的MAC發送一資訊回應訊框以回應行動用戶台(S650)。行動用戶台之MAC接收該資訊回應訊框,及將已接收資訊服務的內容經由一MIH_info.confirm訊息傳遞至其MIH(S660)。Figure 6 is a flow chart of a procedure for obtaining an information service according to the related art. Referring to FIG. 6, an MIH of a mobile subscriber station (MS) transmits an MIH_info.request message to its MAC to request an information service (S610). The MAC of the mobile subscriber station then transmits an information request frame to a base station (BS) (S620). One of the base stations, the MAC, transmits the information request from the mobile subscriber station to its MIH via the MIH_info.indication message (S630). The base station MIH then passes a reserved media independent information service to the MAC layer via a MIH_info.response message (S640). This causes the base station's MAC to send a message response frame in response to the mobile subscriber station (S650). The MAC of the mobile subscriber station receives the information response frame and transmits the content of the received information service to its MIH via a MIH_info.confirm message (S660).
然而,在寬頻無線存取系統之相關技術中,一試圖從另一介面網路(如,IEEE 802.11、3GPP或3GPP2)遞交至一寬頻無線存取系統的多模式行動用戶台,一試圖遞交至一在相同寬頻無線存取系統中之另一基地台的行動用戶台,或一在一寬頻無線存取系統之基地台內執行一初始網路存取程序的行動用戶台,係無法知道一基地台之MIH能力是否可用。因此,需求一種能解決相關技術之問題的發明。However, in the related art of the broadband wireless access system, an attempt is made to submit to a multi-mode mobile subscriber station of a broadband wireless access system from another interface network (eg, IEEE 802.11, 3GPP, or 3GPP2). A mobile subscriber station of another base station in the same broadband radio access system, or an active subscriber station that performs an initial network access procedure in a base station of a broadband radio access system, cannot know a base. Whether the MIH capability of Taiwan is available. Therefore, there is a need for an invention that solves the problems of the related art.

In an aspect of the invention, the multi-mode mobile subscriber station and the base station negotiate with each other for mutual MIH capabilities.
依據本發明第六具體實施例,一行動用戶台經由一來自基地台之信標訊息獲得MIH能力資訊。According to a sixth embodiment of the present invention, a mobile subscriber station obtains MIH capability information via a beacon message from the base station.
基地台可不僅將有關相鄰寬頻無線存取系統基地台之MIH能力資訊提供予目前存取之行動用戶台,且亦可提供關於能接收信號之無線LAN存取點(AP)或附接點(POA)及胞狀基地台的MIH能力資訊。此可經由一相鄰基地台廣告(MOB-NBR-ADV)廣播訊息而完成。較佳的是,此訊息可包括一指示對應的基地台及AP或POA是否可將一從資訊服務(IS)伺服器取得之資訊服務提供予一行動用戶台的資訊服務(IS)支援欄位。表16顯示一附加至MOB-NBR-ADV訊息之格式以表示關於一相鄰基地台及無線LAN POA或胞狀系統基地台的MIH能力資訊之實例。The base station can provide not only the MIH capability information about the adjacent broadband wireless access system base station to the currently accessed mobile subscriber station, but also the wireless LAN access point (AP) or the attachment point that can receive the signal. (POA) and MIH capability information of the cell base station. This can be done via a neighboring base station advertisement (MOB-NBR-ADV) broadcast message. Preferably, the message may include an information service (IS) support field indicating whether the corresponding base station and the AP or POA can provide an information service obtained from an information service (IS) server to a mobile subscriber station. . Table 16 shows an example of the format attached to the MOB-NBR-ADV message to indicate MIH capability information for a neighboring base station and a wireless LAN POA or cell system base station.
一新近附加至先前MOB-NBR-ADV訊息之MIH INFO位元映像表示關於一鄰近一行動用戶台正存取之寬頻無線網路基地台的一可用無線LAN POA或胞狀系統基地台之MIH能力及IS支援。一MIH INFO位元映像2指示位於相鄰寬頻無線存取基地台(即無線LAN POA或胞狀系統基地台)鄰近之一異質附接點的MIH能力及IS支援存在與否。較佳的是,MIH INFO位元映像2可指示有關位於一同質相鄰基地台鄰近之一異質附接點的MIH能力及IS支援存在與否之資訊,以及一目前基地台之相鄰異質附接點資訊。A MIH INFO bit map newly attached to the previous MOB-NBR-ADV message indicates the MIH capability of an available wireless LAN POA or cell system base station for a broadband wireless network base station that is being accessed by a mobile subscriber station And IS support. A MIH INFO bit map 2 indicates the presence or absence of MIH capabilities and IS support located at one of the heterogeneous attachment points adjacent to the adjacent broadband radio access base station (ie, the wireless LAN POA or the cellular system base station). Preferably, the MIH INFO bit map 2 may indicate information about the presence or absence of MIH capabilities and IS support for a heterogeneous attachment point located adjacent to a homogeneous neighboring base station, and an adjacent heterogeneous base station of the current base station. Contact information.
一用以包括一目前基地台之MIH能力資訊的位元被新增,藉由其一新近進入目前基地台區域之行動用戶台可獲得指示一目前或相鄰基地台之MIH能力及一IS功能是否可依一接收下行鏈路通道描述符(DCD)訊息之方式提供的資訊。行動用戶台使用該資訊以獲得一叢發檔用於將一廣播訊息解碼,從DL-MAP獲得MOB_NBR-ADV訊息的起始位置,且將MOB_NBR-ADV訊息解碼成為一自對應位置接收之廣播訊息。一MIH未知位元係加入MIH INFO位元映像1或2中,用於指示一基地台允許MIH或不允許MIH之出現與否係未知,即基地台之該能力未確認。例如,若發現無線LAN POA可用於MIH INFO位元映像1,且接收諸如[1]可用WLAN POA、[0]可用POA MIH允許及[1]可用WLAN POAMIH未知之位元映像資訊,儘管一無線POA允許遞交存在於目前基地台鄰近,MIH能力的狀態未知。因此,未聯結MIH允許位元的意義。A bit to include MIH capability information of a current base station is added, and an MIH capability and an IS function indicating a current or adjacent base station can be obtained by a mobile subscriber station newly entering the current base station area. Whether the information can be provided in a manner that receives a Downlink Channel Descriptor (DCD) message. The mobile subscriber station uses the information to obtain a burst file for decoding a broadcast message, obtains the start position of the MOB_NBR-ADV message from the DL-MAP, and decodes the MOB_NBR-ADV message into a broadcast message received from the corresponding location. . An MIH unknown bit is added to the MIH INFO bit map 1 or 2 to indicate whether a base station allows MIH or does not allow the presence or absence of MIH to be unknown, that is, the capability of the base station is not confirmed. For example, if a wireless LAN POA is found to be available for MIH INFO bit map 1, and receive such information as [1] available WLAN POA, [0] available POA MIH allowed, and [1] available WLAN POAMIH unknown bit map information, despite a wireless The POA allows submissions to exist in the vicinity of the current base station, and the status of the MIH capability is unknown. Therefore, the meaning of the unallowed MIH allowed bits.
一基地台可藉由將資訊包括在一訊框檢查標頭(FCH)來通知一行動用戶台其MIH能力之可用性。因此,該行動用戶台可在接收FCH後從一MIH能力資訊元素獲得關於對應基地台的MIH能力資訊,以解碼基地台之下行鏈路訊框。此外,行動用戶台可自一IS支援資訊元素獲得有關基地台是否可提供從資訊服務(IS)伺服器獲得的資訊服務至行動用戶台之資訊。表17顯示一可用格式的實例,其中「MIH能力」及「IS支援」資訊元素係附加至FCH訊息。透過此格式,基地台可通知一行動用戶台是否一MIH功能及一資訊服務可支援至該行動用戶台。A base station can inform an mobile subscriber station of the availability of its MIH capabilities by including the information in a frame check header (FCH). Therefore, the mobile subscriber station can obtain the MIH capability information about the corresponding base station from an MIH capability information element after receiving the FCH to decode the downlink frame of the base station. In addition, the mobile subscriber station can obtain information about whether the base station can provide information services obtained from the information service (IS) server to the mobile subscriber station from an IS support information element. Table 17 shows an example of an available format in which the "MIH Capabilities" and "IS Support" information elements are attached to the FCH message. Through this format, the base station can notify a mobile subscriber station whether an MIH function and an information service can be supported to the mobile subscriber station.
[表17]
一基地台可在DL-MAP訊息包括其MIH能力之可用性,且通知一行動用戶台該可用性。已接收用於與基地台同步之DL-MAP訊息的行動用戶台可獲得關於對應基地台的MIH能力資訊。較佳的是,基地台從一IS伺服器獲得一資訊服務且可包括一資訊服務支援欄位,其在DL-MAP訊息中指示是否可提供資訊服務至行動用戶台。表18顯示一格式的實例,其可表示加入一包括在DL-MAP訊息中之資訊元素(IE)的MIH能力資訊。一MIH_Capability_IE通知該網路之MIH能力。該MIH能力可藉由使用MAC管理訊息指示MIH功能訊息可與BS交換,以供MS存取網路之MIH功能的服務。此外,該MIH_Capability_IE通知透過目前BS由網路之MIH功能支援的MIH服務類型。提供網路之MIH功能的能力指BS能直接使用MIH功能之服務,且BS能經由NCMS存取MIH功能實體。A base station may include the availability of its MIH capabilities in the DL-MAP message and inform a mobile subscriber station of the availability. The mobile subscriber station that has received the DL-MAP message for synchronization with the base station can obtain MIH capability information about the corresponding base station. Preferably, the base station obtains an information service from an IS server and may include an information service support field indicating whether the information service can be provided to the mobile subscriber station in the DL-MAP message. Table 18 shows an example of a format that can represent MIH capability information added to an information element (IE) included in a DL-MAP message. A MIH_Capability_IE informs the MIH capability of the network. The MIH capability can be exchanged with the BS by using the MAC management message to indicate that the MIH function message can be exchanged for the MS to access the MIH function of the network. In addition, the MIH_Capability_IE notifies the MIH service type supported by the MIH function of the current BS through the current BS. The capability of providing the MIH function of the network refers to the service that the BS can directly use the MIH function, and the BS can access the MIH functional entity via the NCMS.
參數係用以通知目前BS是否可經由NCMS存取MIH功能服務。此應用於一其中目前BS具有MIH功能之能力的情況。若參數係設定成「1」,MS可經由目前BS存取MIH功能,且可使用關聯MIH之MAC管理訊息(如,MOB_MSMIH-REQ、MOB_MSMIH-RSP、MOB_BSMIH-REQ、MOB_BSMIH-RSP)以與MIH功能通信。一事件服務支援參數係一用來通知該MIH功能(其可使用BS存取)是否支援事件服務(ES)的參數。一命令服務支援參數係一用來通知該MIH功能(其可使用BS存取)是否支援命令服務(CS)的參數。一資訊服務支援參數係一用來通知該MIH功能(其可使用BS存取)是否支援資訊服務(IS)的參數。。The parameter is used to inform the current BS whether the MIH function service can be accessed via the NCMS. This applies to a case where the current BS has the capability of MIH function. If the parameter is set to "1", the MS can access the MIH function via the current BS, and can use the MAC management message of the associated MIH (eg, MOB_MSMIH-REQ, MOB_MSMIH-RSP, MOB_BSMIH-REQ, MOB_BSMIH-RSP) to interact with the MIH. Functional communication. An event service support parameter is used to inform the MIH function (which can use the BS access) whether to support the parameters of the event service (ES). A command service support parameter is a parameter for notifying whether the MIH function (which can use the BS access) supports the command service (CS). An information service support parameter is used to notify the MIH function (which can use the BS access) whether to support the parameters of the information service (IS). .
TLV(類型、長度及值)係用於與一基地台協商關聯媒體獨立遞交之功能。在包括一MIH層之行動用戶台施行MIH功能的情況下,行動用戶台設定一對應位元以傳輸至一基地台。若包括一MIH層之基地台係能支援此功能,則該基地台在一欲傳輸之回應訊息中設定該位元。The TLV (Type, Length, and Value) is used to negotiate the independent delivery of associated media with a base station. In the case where the mobile subscriber station including an MIH layer performs the MIH function, the mobile subscriber station sets a corresponding bit to transmit to a base station. If the base station including an MIH layer can support this function, the base station sets the bit in a response message to be transmitted.
關於資訊服務,當試圖經由一過基地台接收資訊服務時,一行動用戶台設定一對應位元以進行請求。若該基地台係能藉由與一資訊服務伺服器通信或藉由作為資訊服務伺服器,以將資訊服務提供至行動用戶台,該基地台藉由設定該位元回應以致能在行動用戶台及基地台間協商。Regarding the information service, when attempting to receive an information service via a base station, an action subscriber station sets a corresponding bit to make a request. If the base station can provide information services to the mobile subscriber station by communicating with an information service server or by acting as an information service server, the base station can activate the subscriber station by setting the bit response Negotiation between the base stations.
表19根據本發明之一具體實施例在SBC-RSP訊息或REG-RSP訊息中依一TLV格式顯示該MIH能力資訊。如表19中所示,若MS將該對應位元設定成「1」且基於該設定發送一請求,此指示該對應能力係由MS之MIH支援。若BS將對應位元設成「1」且因此發送一回應,此指示該對應能力係由包含BS之網路的MIH功能支援。或者是,一「0」之位元設定指示未支援該能力。Table 19 shows the MIH capability information in a TLV format in an SBC-RSP message or a REG-RSP message according to an embodiment of the present invention. As shown in Table 19, if the MS sets the corresponding bit to "1" and sends a request based on the setting, this indicates that the corresponding capability is supported by the MIH of the MS. If the BS sets the corresponding bit to "1" and therefore sends a response, this indicates that the corresponding capability is supported by the MIH function of the network containing the BS. Or, a bit setting of "0" indicates that the capability is not supported.
較佳的是,位元#0指示MIH是否由MS或BS支援。此外,位元#1指示是否支援ES,位元#2指示是否支援CS且位元#3指示是否支援IS。詳盡言之,位元#3查詢BS是否有能力以從IS伺服器接收IS,或BS是否可施行IS伺服器之能力。Preferably, bit #0 indicates whether the MIH is supported by the MS or the BS. Further, bit #1 indicates whether or not the ES is supported, bit #2 indicates whether CS is supported and bit #3 indicates whether or not IS is supported. In detail, bit #3 queries whether the BS has the ability to receive IS from the IS server, or whether the BS can implement the IS server.
此外,位元#0其一不同指示係若此指示符被設定且由BS傳輸,該BS可經由過NCMS存取MIH功能,或MIH功能的服務可由BS提供。此外,若該指示符的值被設定且傳輸至MS,此指示係可使用與MIH關聯(如MOB_MSMIH-REQ、MOB_MSMIH-RSP、MOB_BSMIH-REQ、MOB_BSMIH-RSP)之MAC管理訊息。In addition, bit #0 has a different indication that if this indicator is set and transmitted by the BS, the BS can access the MIH function via the NCMS, or the service of the MIH function can be provided by the BS. In addition, if the value of the indicator is set and transmitted to the MS, the indication may use MAC management messages associated with the MIH (eg, MOB_MSMIH-REQ, MOB_MSMIH-RSP, MOB_BSMIH-REQ, MOB_BSMIH-RSP).
表20及表21分別顯示能包括MIH能力之其他格式。當藉由試圖遞交而執行一網路再進入程序,或在已與欲執行一初始網路進入程序之目標基地台完成測距程序後,一行動用戶台可當與基地台協商基本能力時,在一欲傳輸之SBC-REQ訊息中包括其MIH能力資訊,且接著將該訊息傳輸至基地台。表21以一TLV格式顯示可包括在一SBC-REQ訊息中之MIH能力欄位的實例。若MIH能力係可用,一目標基地台藉由將MIH能力位元設成1來傳輸一SBC-RSP訊息。在此情況下,MIH能力位元係包括在表20所示之格式中的SBC-RSP訊息之TLV內。Tables 20 and 21 show other formats that can include MIH capabilities, respectively. When a network re-entry procedure is performed by attempting to submit, or after a ranging procedure has been completed with a target base station that is to perform an initial network entry procedure, an active subscriber station can negotiate basic capabilities with the base station. The MIH capability information is included in an SBC-REQ message to be transmitted, and then the message is transmitted to the base station. Table 21 shows an example of a MIH capability field that can be included in an SBC-REQ message in a TLV format. If the MIH capability is available, a target base station transmits an SBC-RSP message by setting the MIH capability bit to one. In this case, the MIH capability bits are included in the TLV of the SBC-RSP message in the format shown in Table 20.
一行動用戶台可在一欲傳輸用於執行一註冊程序之MOB-REG-REQ訊息中包括其MIH能力資訊,然後將該訊息傳輸至基地台。表20顯示依一TLV格式顯示包括在REG-REQ訊息中之MIH能力欄位的實例。若MIH能力係可用,一目標基地台藉由將MIH能力位元設成1來傳輸一REG-RSP訊息。在此情況下,MIH能力位元係包括在表20所示之格式中的REG-RSP訊息之TLV內。A mobile subscriber station may include its MIH capability information in a MOB-REG-REQ message intended to transmit a registration procedure and then transmit the message to the base station. Table 20 shows an example of displaying the MIH capability field included in the REG-REQ message in a TLV format. If the MIH capability is available, a target base station transmits a REG-RSP message by setting the MIH capability bit to one. In this case, the MIH capability bits are included in the TLV of the REG-RSP message in the format shown in Table 20.
在施行掃描時,一行動用戶台之MAC層從基地台接收一包括MIH能力資訊之信標訊息。因此,行動用戶台之MAC層將此資訊包括在一Link_Available觸發裡且將該資訊通知一MIH。When performing the scanning, the MAC layer of a mobile subscriber station receives a beacon message including MIH capability information from the base station. Therefore, the MAC layer of the mobile subscriber station includes this information in a Link_Available trigger and notifies the MIH of the information.
表22顯示一用於在一Link_Available觸發中包括MIH能力資訊之具體實施例。Table 22 shows a specific embodiment for including MIH capability information in a Link_Available trigger.
在從基地台接收包括MIH能力資訊之DL-MAP後,行動用戶台之MAC層經由一「MIH_Capability.indication」原語傳遞基地台的MIH能力資訊至其MIH。現「MIH_Capability.indication」原語之一具體實施例將加以解釋。After receiving the DL-MAP including the MIH capability information from the base station, the MAC layer of the mobile subscriber station transmits the MIH capability information of the base station to its MIH via a "MIH_Capability.indication" primitive. A specific embodiment of the "MIH_Capability.indication" primitive will now be explained.
首先將解釋「MIH_Capability.indication」原語的功能。一行動用戶台之MAC層經由此原語將一目標基地台的MIH能力資訊傳遞至其MIH。該原語接著係從MIH傳遞至一上管理實體,以將一相鄰基地台的MIH_Capability資訊傳遞至上管理實體。上管理實體可用以決定是否欲執行遞交至一網路支援MIH。此外,可藉由MAC層直接將原語傳遞至上管理實體。該上管理實體可將此資訊用於決定相對於網路支援MIH之可能性施行遞交。The function of the "MIH_Capability.indication" primitive will be explained first. The MAC layer of an active subscriber station transmits MIH capability information of a target base station to its MIH via this primitive. The primitive is then passed from the MIH to an upper management entity to pass the MIH_Capability information of a neighboring base station to the upper management entity. The upper management entity can be used to decide whether to perform the delivery to a network support MIH. In addition, the primitives can be directly passed to the upper management entity by the MAC layer. The upper management entity may use this information to determine the likelihood of delivery relative to the network to support the MIH.
「MIH_Capability.indication」原語之語意係表示如下。The meaning of the primitive "MIH_Capability.indication" is as follows.
MIH_Capability.indication{來源,目的,LinkIdentifier,BS MIH能力,BS事件服務支援,BS命令服務支援,BS IS支援,}MIH_Capability.indication{Source, destination, LinkIdentifier, BS MIH capability, BS event service support, BS command service support, BS IS support,}
在一寬頻無線存取系統之情況中,「BS MIH Capability」及「BS IS支援」參數分別表示一新基地台之MIH能力及IS支援的可能性。依據各異質媒體,「BS MIH Capability」及「BSIS支援」參數表示一無線LAN(IEEE 802.11)系統之POA、一3GPP系統的節點B、或3GPP2系統之一基地台(BTS)的MIH能力及IS支援的可能性。In the case of a broadband wireless access system, the "BS MIH Capability" and "BS IS Support" parameters respectively indicate the MIH capabilities of a new base station and the possibility of IS support. According to the heterogeneous media, the "BS MIH Capability" and "BSIS Support" parameters indicate the POH of a wireless LAN (IEEE 802.11) system, the Node B of a 3GPP system, or the MIH capability and IS of a base station (BTS) of the 3GPP2 system. The possibility of support.
以下解釋用於產生「MIH_Capability.indication」原語之時間。若一行動用戶台之MAC層接收含有一附接點之MIH能力資訊的一信標、DL-MAP或相鄰者廣告訊息,則會產生「MIH_Capability.indication」原語以將資訊傳遞至MIH或上管理實體。若MIH發現一新網路(如IEEE802.16、IEEE802.11、3GPP、或3GPP2)具有一MIH功能或該新網路支援資訊服務(IS),則會產生「MIH_Capability.indication」原語以將所發現之資訊通知一上管理實體。The time for generating the "MIH_Capability.indication" primitive is explained below. If the MAC layer of an mobile subscriber station receives a beacon, DL-MAP or neighbor advertisement message containing MIH capability information of an attachment point, a primitive "MIH_Capability.indication" is generated to transmit the information to the MIH or the upper layer. Manage entities. If the MIH finds that a new network (such as IEEE802.16, IEEE802.11, 3GPP, or 3GPP2) has an MIH function or the new network support information service (IS), the "MIH_Capability.indication" primitive is generated to The information found is notified to the management entity.
以下解釋接收「MIH_Capability.indication」原語之影響。在接收該原語後,MIH或上管理實體獲得目標基地台的MIH能力資訊。The following explains the effect of receiving the primitive "MIH_Capability.indication". After receiving the primitive, the MIH or the upper management entity obtains the MIH capability information of the target base station.
依據本發明之較佳具體實施例,現將解釋在寬頻無線存取系統中用於將基地台的MIH能力提供至一多模式行動用戶台的方法。在以下具體實施例中,係描述自IEEE 802.11系統遞交至IEEE 802.16系統。然而,如先前描述中所揭,本發明係可應用於在一寬頻無線存取網路、一無線LAN、及一胞狀網路至少其一中操作的系統。因此,致能遞交至各種無線LAN、胞狀網路或其他寬頻無線存取網路。In accordance with a preferred embodiment of the present invention, a method for providing base station MIH capabilities to a multi-mode mobile subscriber station in a broadband wireless access system will now be explained. In the following specific embodiments, the description is submitted from an IEEE 802.11 system to an IEEE 802.16 system. However, as disclosed in the foregoing description, the present invention is applicable to a system operating in at least one of a wideband wireless access network, a wireless LAN, and a cellular network. Therefore, it can be delivered to various wireless LANs, cellular networks or other broadband wireless access networks.
如下解釋根據本發明一具體實施例之方法。首先,一基地台初始在一DL-MAP的一資訊元素(IE)內包括MIH能力及IS(資訊服務)支援資訊,接著傳輸該DL-MAP。在根據本發明之此具體實施例的方法中,係說明自一無線LAN遞交。較佳的是,該無線LAN在IEEE 802.11系統中操作。A method in accordance with an embodiment of the present invention is explained as follows. First, a base station initially includes MIH capabilities and IS (Information Service) support information in an information element (IE) of a DL-MAP, and then transmits the DL-MAP. In the method according to this embodiment of the invention, the description is submitted from a wireless LAN. Preferably, the wireless LAN operates in an IEEE 802.11 system.
第7圖顯示一基地台當一目前在IEEE802.11系統中操作之多模式行動用戶台試圖遞交至一IEEE 802.16系統時,藉由在DL-MAP中包括MIH能力資訊及IS支援資訊來傳輸一DL-MAP,且接收用於MAC同步化之DL-MAP的實例。Figure 7 shows a base station transmitting a UH capability information and IS support information in the DL-MAP when a multi-mode mobile subscriber station operating in an IEEE 802.11 system attempts to submit to an IEEE 802.16 system. DL-MAP, and receives an instance of DL-MAP for MAC synchronization.
參考第7圖,一多模式行動用戶台(MSS)之IEEE 80211 MAC藉由週期性或請求掃描來測量目前連接鏈路的品質。若目前連接之鏈路的品質已降級,一「Link_Going_Down」觸發會傳輸至MSS的MIH(S710)。在搜尋一新鏈路後,MSS之IEEE 802.16 MAC將一「Link_Available」觸發傳輸至MSS的MIH(S720)。該MSS之802.16MAC接著接收DL-MAP及將其解碼,其係每一訊框傳輸。MSS之802.16MAC從DL-MAP獲得一目標基地台之MIH能力資訊及IS支援資訊(S730)。之後,MSS之802.16MAC將目標基地台之MIH能力及IS支援資訊經由一「MIH_Capability_indication」原語傳輸至MSS之MIH(S740)。Referring to Figure 7, the IEEE 80211 MAC of a Multi-Mode Mobile Subscriber Station (MSS) measures the quality of the currently connected link by periodic or request scanning. If the quality of the currently connected link has been degraded, a "Link_Going_Down" trigger is transmitted to the MIH of the MSS (S710). After searching for a new link, the IEEE 802.16 MAC of the MSS transmits a "Link_Available" trigger to the MIH of the MSS (S720). The 802.16 MAC of the MSS then receives and decodes the DL-MAP, which is transmitted for each frame. The MSS 802.16MAC obtains MIH capability information and IS support information (S730) of a target base station from the DL-MAP. Thereafter, the 802.16MAC of the MSS transmits the MIH capability and IS support information of the target base station to the MIH of the MSS via a "MIH_Capability_indication" primitive (S740).
在一多模式行動用戶台試圖從一IEEE 802.16基地台遞交至另一IEEE 802.16基地台,或一初始網路進入程序係藉由在一IEEE 802.16基地台內啟動一多模式行動用戶台來執行之情況下,MIH能力及IS支援資訊可根據第7圖之實例經由一DL-MAP獲得。In a multi-mode mobile subscriber station attempting to hand over from an IEEE 802.16 base station to another IEEE 802.16 base station, or an initial network entry procedure is performed by initiating a multi-mode mobile subscriber station in an IEEE 802.16 base station. In this case, MIH capabilities and IS support information can be obtained via a DL-MAP according to the example of FIG.
以下解釋根據本發明另一具體實施例之方法。較佳的是,當行動用戶台與一基地台協商基本能力時,MIH能力資訊及IS支援資訊係經由SBC-REQ及SBC-RSP訊息獲得。The method according to another embodiment of the present invention is explained below. Preferably, when the mobile subscriber station negotiates basic capabilities with a base station, MIH capability information and IS support information are obtained via SBC-REQ and SBC-RSP messages.
在本發明之此具體實施例中,係描述遞交至一胞狀網路中之無線LAN、寬頻無線存取網路及無線LAN。較佳的是,該無線LAN係一IEEE 802.11系統。In this particular embodiment of the invention, a wireless LAN, a broadband wireless access network, and a wireless LAN are delivered to a cellular network. Preferably, the wireless LAN is an IEEE 802.11 system.
第8圖顯示當試圖遞交至一IEEE 802.16系統及與一基地台協商基本能力時,一目前在IEEB 802.11系統中操作的多模式行動用戶台經由SBC-REQ及SBC-RSP訊息獲得MIH能力資訊及IS支援資訊之實例。Figure 8 shows that when attempting to submit to an IEEE 802.16 system and negotiating basic capabilities with a base station, a multi-mode mobile subscriber station currently operating in the IEEB 802.11 system obtains MIH capability information via SBC-REQ and SBC-RSP messages and Examples of IS support information.
參考第8圖,若行動用戶台(MSS)目前連接之鏈路的品質係降級,MSS之一IEEE 802.11MAC將一「Link_Going_Down」觸發傳輸至MSS的MIH(S810)。在搜尋一新鏈路後,MSS之IEEE 802.16 MAC將一「Link_Available」觸發傳輸至MSS的MIH(S820)。該MSS接著自一基地台接收一DL-MAP且執行MAC同步化(S830)。之後,該MSS自基地台接收一UL-MAP(S840)。其後,MSS將一RNG-REQ訊息(S850)傳輸至基地台,且基地台發送一RNG-RSP訊息以回應(S860)。Referring to FIG. 8, if the quality of the link currently connected by the mobile subscriber station (MSS) is degraded, one of the MSS IEEE 802.11 MACs transmits a "Link_Going_Down" trigger to the MIH of the MSS (S810). After searching for a new link, the IEEE 802.16 MAC of the MSS transmits a "Link_Available" trigger to the MIH of the MSS (S820). The MSS then receives a DL-MAP from a base station and performs MAC synchronization (S830). Thereafter, the MSS receives a UL-MAP from the base station (S840). Thereafter, the MSS transmits an RNG-REQ message (S850) to the base station, and the base station transmits an RNG-RSP message in response (S860).
在接收到RNG_RSP訊息後,MSS在欲傳輸用於協商基本能力之SBC-REQ訊息中包括其MIH能力資訊,及將該訊息傳輸至基地台(S870)。在回應中,基地台將其MIH能力及IS支援資訊包括在一SBC-RSP訊息中,及將對應訊息發送至MSS(S880)。該MSS在一「M_Basic_Capability_Nego.confirmation」原語中包括基地台的MIH能力資訊,及將其發送至MSS之MIH(S890)。因此,多模式行動用戶台的MIH可辨識該基地台是否支援一MIH功能及資訊服務功能。應注意的是,在步驟S830至S880中,一在IEEE 802.16MAC及行動用戶台的MIH間傳送的原語,及另一在IEEE 802.16MAC及基地台之MIH間傳送的原語被省略。After receiving the RNG_RSP message, the MSS includes its MIH capability information in the SBC-REQ message to be used for negotiating basic capabilities, and transmits the message to the base station (S870). In response, the base station includes its MIH capabilities and IS support information in an SBC-RSP message and sends the corresponding message to the MSS (S880). The MSS includes the MIH capability information of the base station in a primitive "M_Basic_Capability_Nego.confirmation" and sends it to the MIH of the MSS (S890). Therefore, the MIH of the multi-mode mobile subscriber station can identify whether the base station supports an MIH function and an information service function. It should be noted that in steps S830 to S880, a primitive transmitted between the IEEE 802.16 MAC and the MIH of the mobile subscriber station, and another primitive transmitted between the IEEE 802.16 MAC and the MIH of the base station are omitted.
在一多模式行動用戶台試圖從一IEEE 802.16基地台遞交至另一IEEE 802.16基地台,或一初始網路進入程序係藉由在一IEEE 802.16基地台內啟動一多模式行動用戶台來執行之情況下,MIH能力及IS支援資訊可依據第8圖之具體實施例經由SBC-REQ及SBC-RSP訊息獲得。In a multi-mode mobile subscriber station attempting to hand over from an IEEE 802.16 base station to another IEEE 802.16 base station, or an initial network entry procedure is performed by initiating a multi-mode mobile subscriber station in an IEEE 802.16 base station. In this case, MIH capabilities and IS support information can be obtained via SBC-REQ and SBC-RSP messages in accordance with the specific embodiment of FIG.
以下解釋一根據本發明另一具體實施例之方法。較佳的是,當一行動用戶台對一基地台執行註冊程序時,MIH能力資訊及IS支援資訊係經由REG-REQ及REG-RSP訊息獲得。A method in accordance with another embodiment of the present invention is explained below. Preferably, when a mobile subscriber station performs a registration procedure for a base station, MIH capability information and IS support information are obtained via REG-REQ and REG-RSP messages.
在本發明之此具體實施例中,係描述遞交至胞狀網路中之一無線LAN、寬頻無線存取網路及無線LAN。較佳的是,該無線LAN係一IEEE 802.11系統。In this particular embodiment of the invention, a wireless LAN, a broadband wireless access network, and a wireless LAN are delivered to the cellular network. Preferably, the wireless LAN is an IEEE 802.11 system.
第9圖顯示當試圖遞交至一IEEE 802.16系統且對一基地台執行註冊程序時,一目前在IEEE 802.11系統中操作之多模式行動用戶台經由REG-REQ及REG-RSP訊息獲得MIH能力資訊及IS支援資訊之實例。Figure 9 shows that when attempting to submit to an IEEE 802.16 system and performing a registration procedure for a base station, a multi-mode mobile subscriber station currently operating in an IEEE 802.11 system obtains MIH capability information via REG-REQ and REG-RSP messages and Examples of IS support information.
參考第9圖,一多模式行動用戶台(MSS)之IEEE 802.11 MAC藉由週期性或請求掃描來測量MSS目前連接之鏈路的品質。若目前連接鏈路的品質係降級,MSS之IEEE 802.11 MAC將一「Link_Going_Down」觸發傳輸至MSS的MIH(S901)。在搜尋一新鏈路後,IEEE 802.16 MAC將「Link_Available」觸發傳輸至MSS的MIH(S902)。該MSS接著自一基地台(BS)接收一DL-MAP且執行MAC同步化(S903)。之後,MSS自基地台接收一UL-MAP(S904)。其後,MSS將一RNG-REQ訊息(S905)傳輸至基地台,且該基地台發送一RNG-RSP訊息以回應(S906)。Referring to Figure 9, an IEEE 802.11 MAC of a Multi-Mode Mobile Subscriber Station (MSS) measures the quality of the link currently connected by the MSS by periodic or request scanning. If the quality of the currently connected link is degraded, the IEEE 802.11 MAC of the MSS transmits a "Link_Going_Down" trigger to the MIH of the MSS (S901). After searching for a new link, the IEEE 802.16 MAC transmits a "Link_Available" trigger to the MIH of the MSS (S902). The MSS then receives a DL-MAP from a base station (BS) and performs MAC synchronization (S903). Thereafter, the MSS receives a UL-MAP from the base station (S904). Thereafter, the MSS transmits an RNG-REQ message (S905) to the base station, and the base station transmits an RNG-RSP message in response (S906).
MSS接著將SBC-REQ訊息發送至此基地台以協商基本能力(S907),且基地台發送SBC-RSP訊息以回應(S908)。在從基地台接收SBC-RSP訊息後,行動用戶台將其MIH能力資訊包括在欲傳輸用於執行註冊程序的REG-REQ訊息中,且將該訊息傳輸至基地台(S909)。因此,基地台將其MIH能力及IS支援資訊包括在一REG-RSP訊息中,且將訊息發送至MSS以回應(S910)。The MSS then transmits an SBC-REQ message to the base station to negotiate basic capabilities (S907), and the base station transmits an SBC-RSP message in response (S908). After receiving the SBC-RSP message from the base station, the mobile subscriber station includes its MIH capability information in the REG-REQ message to be transmitted for performing the registration procedure, and transmits the message to the base station (S909). Therefore, the base station includes its MIH capability and IS support information in a REG-RSP message, and sends a message to the MSS to respond (S910).
在已自基地台接收到REG-RSP訊息後,行動用戶台將含有基地台之MIH能力資訊的「M_Registration.confirmation」原語傳遞至其MIH(S911)。透過此,多模式行動用戶台之MIH可辨識該基地台是否支援一MIH及資訊服務功能。在步驟S903至S910中,一在IEEE 802.16MAC及行動用戶台之MIH間傳送的原語,及另一在IEEE 802.16MAC及基地台之MIH間傳送的原語被省略在一多模式行動用戶台試圖從一IEEE 802.16基地台遞交至另一IEEE 802.16基地台,或一初始網路進入程序係藉由在IEEE 802.16基地台內啟動一多模式行動用戶台來執行之情況下,MIH能力及IS支援資訊可依據第9圖之具體實施例經由REG-REQ及REG-RSP訊息獲得。After receiving the REG-RSP message from the base station, the mobile subscriber station transmits the primitive "M_Registration.confirmation" containing the MIH capability information of the base station to its MIH (S911). Through this, the MIH of the multi-mode mobile subscriber station can identify whether the base station supports an MIH and information service function. In steps S903 to S910, a primitive transmitted between the IEEE 802.16 MAC and the MIH of the mobile subscriber station, and another primitive transmitted between the IEEE 802.16 MAC and the base station MIH are omitted in a multi-mode mobile subscriber station attempting to An IEEE 802.16 base station is handed over to another IEEE 802.16 base station, or an initial network entry procedure is performed by initiating a multi-mode mobile subscriber station in an IEEE 802.16 base station. MIH capabilities and IS support information may be Obtained via the REG-REQ and REG-RSP messages in accordance with the specific embodiment of FIG.
以下解釋一根據本發明另一具體實施例之方法。在本發明之此具體實施例中,係描述遞交至一胞狀網路中之無線LAN、寬頻無線存取網路及無線LAN。較佳的是,該無線LAN係一IEEE 802.11系統。較佳的是,一行動用戶台自一基地台接收一含有MIH能力之廣播資訊。A method in accordance with another embodiment of the present invention is explained below. In this particular embodiment of the invention, a wireless LAN, a broadband wireless access network, and a wireless LAN are delivered to a cellular network. Preferably, the wireless LAN is an IEEE 802.11 system. Preferably, a mobile subscriber station receives a broadcast message containing MIH capability from a base station.
第10圖顯示一目前在IEEE 802.11系統中操作之多模式行動用戶台(MSS)經由來自一IEEE 802.16基地台(BS)的廣播訊息獲得MIH能力資訊。該MSS將資訊包括在一欲傳輸至MSS之MIH的「Link_Available」觸發中,且當因為目前鏈路之信號退化而掃描另一介面時傳輸該觸發。Figure 10 shows a multi-mode mobile subscriber station (MSS) currently operating in an IEEE 802.11 system obtaining MIH capability information via broadcast messages from an IEEE 802.16 base station (BS). The MSS includes the information in a "Link_Available" trigger for the MIH to be transmitted to the MSS, and transmits the trigger when another interface is scanned because the signal of the current link is degraded.
參考第10圖,一多模式行動用戶台之IEEE 802.11MAC藉由週期性或請求掃描來測量MSS目前連接之鏈路的品質。若目前連接之鏈路的品質係降級,一「Link_Going_Down」觸發會傳輸至MSS的MIH(S1010)。一MSS之更高管理實體或MIH接著導引MSS之IEEE 802.16 MAC施行掃描以搜尋一可用或有空之基地台(S1020)。施行掃描過程之IEEE 802.15MAC自一IEEE 802.16基地台接收一廣播訊息(S1030)。之後,IEEE 802.16 MAC經由「Link_Available」觸發將包括在廣播訊息中之MIH能力資訊傳送至MSS的MIH(S1040)。Referring to FIG. 10, the IEEE 802.11 MAC of a multi-mode mobile subscriber station measures the quality of the link currently connected by the MSS by periodic or request scanning. If the quality of the currently connected link is degraded, a "Link_Going_Down" trigger is transmitted to the MIH of the MSS (S1010). A higher management entity or MIH of an MSS then directs the IEEE 802.16 MAC of the MSS to perform a scan to search for an available or available base station (S1020). The IEEE 802.15 MAC performing the scanning process receives a broadcast message from an IEEE 802.16 base station (S1030). Thereafter, the IEEE 802.16 MAC transmits the MIH capability information included in the broadcast message to the MIH of the MSS via "Link_Available" (S1040).
在一多模式行動用戶台試圖從一IEEE 802.16基地台遞交至另一IEEE 802.16基地台,或一初始網路進入程序係藉由在一IEEE 802.16基地台內啟動一多模式行動用戶台來執行之情況下,MIH能力及IS支援資訊可依據第8圖之具體實施例經由SBC-REQ及SBC-RSP訊息獲得。In a multi-mode mobile subscriber station attempting to hand over from an IEEE 802.16 base station to another IEEE 802.16 base station, or an initial network entry procedure is performed by initiating a multi-mode mobile subscriber station in an IEEE 802.16 base station. In this case, MIH capabilities and IS support information can be obtained via SBC-REQ and SBC-RSP messages in accordance with the specific embodiment of FIG.
以下解釋一根據本發明另一具體實施例之方法。首先,一基地台將其MIH能力資訊及資訊服務(IS)支援資訊包括在一相鄰者廣告(MOB_NBR-ADV)訊息中且傳輸該訊息。一行動用戶獲得該資訊且使用其以決定是否執行遞交。A method in accordance with another embodiment of the present invention is explained below. First, a base station includes its MIH capability information and information service (IS) support information in a neighbor advertisement (MOB_NBR-ADV) message and transmits the message. An action user obtains the information and uses it to decide whether to perform the submission.
參考第11圖,一目前在IEEE 802.11系統中操作之多模式行動用戶台因為目前鏈路的信號品質降級而執行一針對另一介面網路之掃描過程。進行掃描時,多模式行動用戶台藉由接收一自IEEE 802.16基地台(BS)傳輸之相鄰者廣告(MOB_NBR-ADV)訊息而獲得MIH能力資訊。MSS接著將目標基地台之MIH能力資訊及IS支援資訊經由一MIH_Capability.indication原語傳遞至其MIH。較佳的是,可傳遞此原語至一上管理實體。在自掃描過程中獲得MIH能力資訊之情況下,自MOB_NBR-ADV訊息中獲得之MIH能力資訊可經由一「Link_Available」觸發傳遞至MSS之MIH。Referring to FIG. 11, a multi-mode mobile subscriber station currently operating in an IEEE 802.11 system performs a scanning process for another interface network due to degradation of the signal quality of the current link. When scanning, the multi-mode mobile subscriber station obtains MIH capability information by receiving a neighbor advertisement (MOB_NBR-ADV) message transmitted from an IEEE 802.16 base station (BS). The MSS then passes the MIH capability information and IS support information of the target base station to its MIH via a MIH_Capability.indication primitive. Preferably, this primitive can be passed to an upper management entity. In the case of obtaining MIH capability information during the self-scanning process, the MIH capability information obtained from the MOB_NBR-ADV message can be transmitted to the MIH of the MSS via a "Link_Available" trigger.
一多模式行動用戶台之IEEE 802.11 MAC藉由週期性或請求掃描來測量目前已存取鏈路的品質。若目前已存取鏈路的品質係降級,一「Link_Going_Down」觸發係傳輸至MSS的MIH(S1101)。在搜尋一新鏈路後,IEEE 802.16 MAC將「Link_Available」觸發傳輸至MSS的MIH(S1102)。The IEEE 802.11 MAC of a multi-mode mobile subscriber station measures the quality of the currently accessed link by periodic or request scanning. If the quality of the currently accessed link is degraded, a "Link_Going_Down" trigger is transmitted to the MIH of the MSS (S1101). After searching for a new link, the IEEE 802.16 MAC transmits a "Link_Available" trigger to the MIH of the MSS (S1102).
之後,MSS之IEEE 802.16 MAC接收一DL-MAP且將其解碼,其係自基地台每一訊框傳輸(S1103)。此外,IEEE 802.16 MAC檢查間隔,以瞭解一下行鏈路通道描述符(DCD)何時傳輸(S1105)。已接收DCD之行動用戶台可獲得用於由目前基地台編碼一廣播訊息之叢發設定檔。因此,行動用戶台可使用該叢發設定檔將接收的廣播訊息解碼。藉由接收DL-MAP(S1106),MSS可檢查何時傳輸一相鄰者廣告(MOB_NBR-ADV)訊息,以接收該訊息。目前基地台的MIH能力資訊及IS支援資訊係藉由使用經由DCD獲得之下行鏈路叢發設定檔將已接收之相鄰者廣告(MOB_NBR-ADV)訊息解碼而獲得(S1107)。該行動用戶台接著經由一「MIH_Capability.indication」原語傳遞目前基地台的MIH能力資訊及IS支援資訊至其MIH(S1108),其中可將該原語傳遞至上管理實體(S1108)。Thereafter, the IEEE 802.16 MAC of the MSS receives a DL-MAP and decodes it, which is transmitted from the base station to each frame (S1103). In addition, the IEEE 802.16 MAC checks the interval to see when the Link Channel Descriptor (DCD) is transmitted (S1105). The mobile subscriber station that has received the DCD can obtain a burst profile for encoding a broadcast message by the current base station. Therefore, the mobile subscriber station can use the burst profile to decode the received broadcast message. By receiving the DL-MAP (S1106), the MSS can check when a neighbor advertisement (MOB_NBR-ADV) message is transmitted to receive the message. The MIH capability information and the IS support information of the base station are currently obtained by decoding the received neighbor advertisement (MOB_NBR-ADV) message using the downlink burst profile obtained by the DCD (S1107). The mobile subscriber station then transmits the current base station MIH capability information and IS support information to its MIH via a "MIH_Capability.indication" primitive, wherein the primitive can be passed to the upper management entity (S1108).
在試圖從一IEEE 802.16基地台遞交至另一IEEE 802.16基地台,或一初始網路進入程序係藉由在一IEEE 802.16基地台內啟動一多模式行動用戶台來執行之情況下,該多模式行動用戶台可依據第11圖所示之具體實施例經由MOB_NBR-ADV訊息獲得MIH能力及IS支援資訊。In the case of attempting to transfer from an IEEE 802.16 base station to another IEEE 802.16 base station, or an initial network entry procedure is performed by launching a multi-mode mobile subscriber station in an IEEE 802.16 base station, the multi-mode The mobile subscriber station can obtain MIH capabilities and IS support information via the MOB_NBR-ADV message in accordance with the specific embodiment shown in FIG.
因此,本發明提供以下優勢。首先,一多模式行動用戶台試圖從另一介面網路(如IEEE 802.11、3GPP、3GPP2)遞交至一寬頻無線存取系統,一行動用戶台試圖遞交至相同寬頻無線存取系統中之另一基地台,或一行動用戶台在一基地台的寬頻無線存取系統中執行一初始網路進入程序,藉由試圖連接至基地台以獲取一目標基地台之MIH能力及IS支援資訊,因此易於辨識關聯媒體獨立遞交之目標基地台的能力。Accordingly, the present invention provides the following advantages. First, a multi-mode mobile subscriber station attempts to submit from another interface network (such as IEEE 802.11, 3GPP, 3GPP2) to a broadband wireless access system, and an active subscriber station attempts to submit to another of the same broadband wireless access systems. The base station, or a mobile subscriber station, performs an initial network entry procedure in a base station's broadband wireless access system, thereby attempting to connect to the base station to obtain the MIH capability and IS support information of a target base station, thereby facilitating Identify the capabilities of the target base station to which the associated media is independently submitted.
