Description of the Invention: [Technical Field of the Invention] The present invention relates to a system, apparatus and method for wireless communication. More specifically, the present invention relates to cellular wireless communication system technology that enables user equipment to convert its serving cells. [Prior Art] The abbreviations used in the following statements are defined as follows: DCH-specific channel DPDCH-specific entity data channel DPCCH-specific entity control channel EDCH Enhanced uplink-specific channel E-DPDCH Enhanced proprietary entity data channel E-RNTI enhancement Radio network temporary identification code HARQ hybrid automatic repeat request HSUPA high speed uplink packet access IE information element MAC-e enhanced media access control Node B For example, base station and other network node RNC radio network controller RNTI radio network temporary identification code RRC radio resource control SG service permission UE, for example, the user equipment of the mobile terminal, etc., is concerned with the uplink of the 1300312 packet data transportation mentioned in, for example, the attached file A. Road DCH (EDCH), file A is the 6th release version of 3GPPTS 25.309, third generation partner program; technical specification for class-collected line access network; enhanced uplink FDD; overall specification; 2 (6th release version). In HSUPA, today's enhancements are made by assigning some packet scheduler functions to Node Bs to provide faster burst scheduling, so it can be provided by Layer 3 (L3, Network Layer) of the RNC. Instant transportation. The principle of φ driving this approach is that with faster links, it is possible to make the uplink power resources more efficiently shared among the packet data users. For example, when the user completes the packet transmission, the predetermined resource can be immediately used by another user. This technique is intended to avoid variability in the distribution of noise peaks, such as when high data rates are allocated to high data rate applications that are performing bursts. In the current architecture, the packet scheduler is located at the RNC. Since at least a portion of the bandwidth is limited to the RRC communication interface between the RNC and the UE, the function of the packet scheduler is limited to match the immediate transportation. Therefore, to accommodate variability, the packet scheduler must carefully configure the uplink power to account for the impact of inactive users during the next scheduled period. However, this solution is considered to be very inefficient when used for high data rate allocation and long release timer values. When using EDCH, most of the packet scheduler functions are transferred to Node B, that is, there is a Node B scheduler responsible for handling the configuration of the uplink resources and including the SG controlling the UE.
每次當UE進入一個新細胞時，該UE接收源自RNC 1300312 且透過RRC傳訊之SG，或者源自服務中之Node B且透過 第2層（L2，資料連結層）傳訊之SG(絕對許可通道）。 然而，當UE從一個細胞移動至另一個細胞時，卻沒有 方法用以保持SG。因此使得服務之連續性變得困難而且 HSUPA之功能被限制為以保證之位元傳輸速率有效率地支 援服務。 此外，RNC可從所接收到之資料存取所預定之許可 _ 值，而且當細胞轉換時，RNC可將該預定之許可值包含於 RRC傳訊中。然而，由於SG係根據E-DPDCH到DPCCH 之最大功率比而被授與，故UE可被允許將其使用作為預定 資料，就RNC而言，此估計值係不明確且可能常有大的錯 誤。換言之，RNC係困難去估計被服務細胞所使用之SG 值，因此，於細胞轉換時RNC亦係困難去保持正確之SG 值。 【發明内容】 依本發明之示範實施例，係為一種方法，該方法包括 φ 儲存第一服務許可（SG)值以作為在第一服務細胞中使用、進 入第二服務細胞、接收源自更高一層之資訊元件、假如資 訊元件並未包含第二SG值時保持第一 SG值及假如資訊元 件包含第二SG值時將第一 SG值變更為第二SG值。 依本發明之另一示範實施例，係為一種行動終端機， 該行動終端機包括當行動終端機位於第一服務細胞中時用 以儲存第一服務許可（SG)值之記憶體、當進入第二服務細胞 時用以接收源自更高一層之資訊元件之裝置、用以測定是 1300312 否資訊元件包含第二SG值之裝置、假如資訊元件並未包含 第二SG值時用以保持第一 SG值之裝置、及假如資訊元件 包含第二SG值時用以將第一 SG值變更為第二SG值之裝 置。 · 依本發明之另一示範實施例，係為一種機器可讀之指 令程式，該程式係具體地收錄於資訊方面之媒體並且係可 由數位資料處理器所執行，用以針對於建立服務許可（SG) 執行動作，其中該動作包括儲存第一服務許可（SG)值以作為 在第一服務細胞中使用、當進入第二服務細胞時接收源自 更高一層之資訊元件、測定是否資訊元件包含第二SG值、 假如資訊元件並未包含第二SG值時保持第一 SG值及假如 資訊元件包含第二SG值時將第一 SG值變更為第’二SG值。 【實施方式】 茲參照附圖，詳細說明本發明之實施例。 依本發明之示範實施例，至少一部份係有關提供例如 於附件之文件Α所提及之用以封包資料運輸之上行鏈路 DCH(EDCH)之增強，文件A之名稱為第6發行版本之3GPP TS 25.309,第三代合作伙伴計晝；類集線電存取網路之技 術說明書；增強式上行鏈路FDD;整體性說明書；階段2(第 6發行版本），其亦為本說明書之一部分。 茲參照圖1之簡易區塊示意圖，係說明適合使用於本 發明之示範實施例之各種不同電子設備。圖1之無線網路1 包括UE 10、Node B(基地台）12、RNC 14。UE 10包括資料 處理器（DP) 10A、用以儲存程式（PROG) 10C之記憶體（MEM) 1300312 10B及用以與Node B 12進行雙向無線通訊之合適射頻（RF) 收發器10D〇Node B 12亦包括DP 12A、用以儲存PROG 12C 之MEM 12B及合適之RF收發器12D«Node B 12係經由資 料路徑13與RNC 14連接，而RNC 14亦包括DP 14A及用 以儲存 PROG 14C 之 MEM 14B。上述之 PROGs 10C、12C 及14C係被認定為包含程式指令，因此當其被組合之DP所 執行時，使得電子裝置能夠依本發明之示範實施例而運 作，而其細節將詳述如下。如圖1顯示，Uu介面係為UTRAN 與UE間之介面，而Iu係為RNC或BSC(基地台控制器）與 3G(第3代行動通訊技術）核心網路（CN)之互連點。 一般而言，依本發明各種不同實施例之UE 10可包括 例如蜂巢式行動電話、具有無線通訊功能之個人數位助理 (PDAs)、具有無線通訊功能之可攜式電腦、影像拍攝裝置（例 如，具有無線通訊功能之數位相機）、具有無線通訊功能之 遊戲裝置、具有無線通訊功能之音樂儲存與播放裝置、可 無線存取與瀏覽網際網路之網際網路裝置及具有上述功能 之混合組合之可攜式裝置或終端機。 為履行本發明之實施例，乃係可藉UE 10之DP 10A與 其他DPs、或藉硬體、或藉硬體與軟體之組合，而執行電腦 軟體。 MEMs 10B、12B及14B之類型可為適合於區域技術環 境之任何類型並且可被使用於任何適合之資料儲存技術， 諸如半導體基礎之記憶體裝置、磁性記憶體裝置與系統、 光學記憶體裝置與系統、固定式記憶體及抽取式記憶體之 9 1300312 類等。DPs 10A、12A及14A之類型可為適合於區域技術環 境之任何類型，並且可包括例如一個或多個一般用途之電 腦、特殊用途之電腦、微處理器、數位信號處理器（DSPs) 及根據多核心處理器架構之處理器之類等。 ~ 接下來將詳述本發明之示範實施例中有關當UE經歷 細胞轉換時如何測定UE之SG值。依本發明之實施例，當 從事於RRC傳訊時，在E-DPDCH中服務許可（SG)資訊元 件（IE)則變成為選擇項目，並且當SG IE未呈現時，UE 10 • 則保持SG使其相同於細胞轉換前所使用之SG。依本發明 之另一實施例，當排程E-DCH細胞資訊時，SG亦將變成 為選擇項目。 圖2之圖示說明，係源自3GPP TS 25.331之第10.3.6.99 節（如附件之文件B並且其亦為本說明書之一部分）之 E-DPDCH資訊及本發明所最關注之服務許可資訊元件（如 圖2B所示）。依本發明之示範實施例，該IE係變成為選擇 項目並且被標示為“Need”屬性之OP (代表“選擇項目”）。當 UE 10經歷EDCH服務細胞轉換時，其更高一層則與UE 10 鲁溝通以組構具有SG值之MAC-e於新細胞中使用，並且指 示UE 10是否應該使用其次要E-RNI1監視絕對許可訊息。 更具體言之，當進入新細胞時，其更高一層指示UE應該監 視主要E_RNT1或次要E-RN1TI。此處所謂之“更高一層”係 指與UE溝通之實體，例如包括Node B及RNC之類等。 茲參照圖3之流程圖，係圖示說明本發明示範實施例Each time the UE enters a new cell, the UE receives the SG originating from the RNC 1300312 and transmitting through the RRC, or the SG originating from the Node B in the service and communicating through the Layer 2 (L2, data link layer) (absolute permission aisle). However, when the UE moves from one cell to another, there is no way to maintain the SG. As a result, the continuity of the service becomes difficult and the functionality of HSUPA is limited to efficiently support the service at a guaranteed bit rate. In addition, the RNC may access the predetermined license_value from the received data, and when the cell transitions, the RNC may include the predetermined grant value in the RRC communication. However, since the SG system is granted according to the maximum power ratio of the E-DPDCH to the DPCCH, the UE can be allowed to use it as a predetermined data, and in the case of the RNC, this estimate is ambiguous and may often have a large error. . In other words, the RNC is difficult to estimate the SG value used by the serving cells, so RNC is also difficult to maintain the correct SG value at the time of cell switching. SUMMARY OF THE INVENTION According to an exemplary embodiment of the present invention, a method includes φ storing a first service grant (SG) value for use in a first serving cell, entering a second serving cell, receiving a source derived from The information element of the higher layer, if the information element does not include the second SG value, maintains the first SG value and changes the first SG value to the second SG value if the information element includes the second SG value.

According to an embodiment of the present invention, when engaged in RRC communication, a Service Grant (SG) Information Element (IE) becomes a selection item in the E-DPDCH, and when the SG IE is not presented, the UE 10 • keeps the SG It is the same as the SG used before cell transformation. According to another embodiment of the invention, the SG will also become a selection item when scheduling E-DCH cell information.

When the cell is switched, the UE 10 initiates all necessary HARQ 10 1300312 private sequences (step A) aUE 10 continues to make a determination as to whether the transmission originating from the higher layer includes the IE service grant (step b). The type of the higher layer communication includes, for example, RRc communication and transmission performed via the L2 data link layer. If the higher layer of the message contains the ιέ service license, the SG value indicated by the ue 10 message and enter the new cell with the SG value of the indication (step C), σ, UE 10's Serving-Grant and Primary-Grant An Available state variable is set to the value provided by the higher layer. # However, if the higher layer of the message does not contain the IE service license, then the current SG is not changed and the UE enters the new cell with the same SG as the SG used for the old cell (step d). Specifically, UE 10 continues to operate using values previously stored in the Serving-Grant and Primary-Grant-Available state variables. Regardless of the instance (step C or step D), the UE 10 continues to initialize the Stored_Secondary_Grant state variable to "Zero_Grant". As defined in the attached document C, the SG may use a preset value such as Minimiim_Grant or Spring Zero_Grant if the service permission IE is not present at the time of initial access. The name of the document C is 3GPP TS 25.309, the third generation partner program; the technical specification of the class line access network; the media access control (MAC) agreement specification (the sixth release), which is also the specification portion. In addition, since the RRC controls the initial access, it can include, for example, a value equivalent to Minimum-Grant or Zero-Grant, etc., as a Service License IE. In accordance with an exemplary embodiment of the present invention, UE 10 may convert cells within the same Node B 11 1300312. In this example, both the old service cell and the new service cell have the ability to share information internally. In addition, both the old serving cell and the new serving cell are able to exchange information about the SG, which does not need to be engaged in changing the current SG value of the UE 1 when the UE 10 switches from one cell to another cell. In accordance with the above description, an embodiment of the present invention provides a method, apparatus, and computer product for determining whether a service license is specified to a UE when a cell is switched, and whether the UE uses the specified service license value, and when entering a new cell. Do not use the current SG value. In general, the various embodiments of the invention can be implemented in a hardware or special purpose circuit, software, logic or any combination thereof. In the awkward, certain features of the invention may be implemented in hardware, while other features may be implemented in a body or software implemented by, for example, a controller, microprocessor or other computer device. The various features of the invention may be described in detail, for example, by block diagrams, flow diagrams, or other illustrative representations and the like, and the devices, systems, techniques, or methods described in detail can be Body, software, firmware, special purpose circuits or logic, general purpose hardware or controllers or other computer devices, or any combination thereof, and the like. , σ Embodiments of the present invention can be practiced in various components such as integrated circuit modules. The design of the integrated circuit is largely self-contained. Complex and powerful software tools can be used to convert logic levels into semiconductor circuits designed for etching and molding on semiconductor substrates. 12 1300312 Programs provided by, for example, Synopsys Inc., of Mountain View, California and Cadence Design, San Jose, California, use a well-established library of suitable rule design and pre-storage design modules that can be automatically routed on a semiconductor wafer. Conduct the conductor and find the component. Once the design of the semiconductor circuit is completed, the design results in accordance with standard electronic sputum (eg, Opus, GDSII, etc.) can be transmitted to a semiconductor fabrication facility or "fab" manufacturing. The present invention has been described with reference to the drawings and examples, and many variations and modifications may be made without departing from the spirit and scope of the invention.
