Description of the Invention (2) Background of the Invention This application claims the key points and advantages of US Provisional Patent Application No. 60 / 282,486 filed on April 10, 2001, and is incorporated into the reference as a whole. Scope of the invention The present invention relates to wireless telecommunications, and more specifically, to the handover of Internet wireless access technologies used in wireless telecommunications. Related techniques and other important points In order to communicate with, for example, other mobile terminals or one or more core networks, some mobile terminals can use more than one form of radio access technology (RAT). In view of the fact that these mobile terminals can use more than two forms of wireless access technology (for example, at different times), they are often referred to as "dual-mode" mobile terminals. Various forms of wireless access technology have been achieved by using related wireless access. The secondary system or network is implemented. Two examples of different wireless access technologies are (1) the Global System for Mobile Communications (GSM) developed in Europe, and its third generation inheritance and UTRAN is essentially a wideband codec Multiple access (W-CDMA) system. An Internet radio access technology (RAT) handover is a procedure in which a mobile terminal is switched from using a first radio access system with a first radio access technology (such as GSM) to having The second wireless access system of the second wireless access technology (such as UTRA). When the quality of the downlink wireless connection of the first wireless access network drops to a certain level, the Internet RAT handover is normally initialized. The quality of the uplink connection of a wireless access network is likely to be worse than the quality of the downlink. -5- This paper size applies to China National Standard (CNS) A4 (210 X 297 mm) gutter 549001 A7 B7 V. Description of the invention (3) In the Internet RAT procedure, the handover command message is sent to the mobile terminal to provide details of the wireless resources to the mobile terminal to be used after the handover (such as when the mobile terminal and the use When the second wireless access technology communicates with the second wireless access network). As an example, consider a situation in which the first wireless access network, the mobile terminal has been using GSM wireless access technology (RAT) Communication, and the measurement authorization dual-mode mobile terminal uses UTRA wireless access technology. In this case, the handover command message transmitted by the GSM wireless access network base station controller across the GSM air interface to the mobile station Contains one or more segments of limited length (each segment is 21 octets). When the 21 octets are not enough to transmit the radio resource information required for the handover, the handover command message Must be segmented to contain multiple segments. However, after the handover command message segment is transmitted, subsequent segments cannot be switched until the reception of the previous segment has been acknowledged The handover command message is transmitted from the base station controller to the mobile terminal via a downlink wireless link. However, in the case where the handover command message is segmented, the successful conversion of the handover command message requires the previous section to acknowledge before the next section transmission. It is converted through the on-chain wireless link. Therefore, if segmentation is used, it is not possible to quickly transfer the handover command message because the quality of the on-chain wireless link is poor. In other words, the handover command in more than two GSM air interface messages Message segmentation has a very unfavorable and unacceptable impact on handover performance. In the case of handover from GSM to UTRAN, the GSM handover command message surrounds the RRC handover to the UTRAN command message. The RRC handover to UTRAN refers to -6. Applicable to China National Standard (CNS) A4 specification (210 X 297 mm) gutter 549001 A7 B7 V. Description of the invention (4) The message contains details of the UTRAN radio resources used in UTRAN after the handover. The RRC handover to UTRAN command message contains a large number of parameters stored in the respective information elements of the RRC handover to UTRAN command message. The size of the RRC handover to UTRAN command message depends on the actual content of these parameters and can be as long as one thousand to two thousand octets. When the RRC handover to UTRAN command message is so large, it obviously cannot be installed in the non-segmented GSM air interface message. As a result, the R R C handover to U T R A N command message must be segmented. A variety of techniques have been used that attempt to reduce the size of handover command messages and thus avoid handover command message segments. For example, the first exemplary technique is pre-configuration. There are two basic forms of pre-configuration. In a predefined configuration, the network can prepare and download one or more wireless configurations to a mobile terminal. This pre-defined wireless configuration contains a large number of wireless carrier parameters, transmission channel parameters, and physical channel parameters. Before the RAT handover, UTRAN first asks which configuration is stored in the mobile terminal. In the case where a suitable pre-defined configuration is stored in the mobile terminal, UTRAN can refer to the storage configuration and then only needs to signal some additional parameters to be used in addition to the storage parameters related to the pre-defined configuration. The second form of pre-configuration is preset parameter configuration. In the preset parameter configuration, some parameters have preset values specified by a standard, such as the RRC protocol specification TS 25.33 1. The preset parameter configuration can be used in the same way, but because it does not need to be downloaded, it can be used more conveniently. As the second demonstration technology for reducing the length of the handover command message, multiple -7-, this paper size applies the Chinese National Standard (CNS) A4 specification (210X297 mm) 549001 A7 B7 V. Description of the invention (5) Initially unnecessary The parameters can be omitted from the handover command message. However, the assumption made by this technique is that the functions corresponding to these parameters do not need to be configured immediately upon handover. As with the third demonstration technique, the use of the parameter minimum range can be predetermined for some parameters that are converted when using pre-configuration. In other words, the size of an information element in the handover command message can be reduced by using a subrange of information parameter values reserved for mobile terminals that are performing an Internet RA transfer. U.S. Patent Application Serial No. 09 / 483,743, filed January 17, 2000, titled 'Methods and Systems for Improved Inter System Handover' provides a description of this third technology, which is fully incorporated herein by reference. This third technique helps to further reduce the size of the handover command message, although there are sometimes performance losses. Although different technologies have been used to reduce the size of handover command messages, handover command messages are still close to the limitations imposed by the effective space in non-segmented GSM air interface messages. Unless other machinery is defined, any space left in the RRC handover to the UTRAN command message is helpful for additional parameter inclusion. When using pre-configuration, one of the parameters that must be included in the RRC handover to the UTRAN command message is an information element with a preset DPCH compensation value. Those skilled in this art will understand that DPCH refers to the exclusive Physical channel, which corresponds to an extended code (refer to, for example, 3GPP TS 25.21 1, v.3.2.0 "Physical Channel and Mapping (FDD) of the transmission channel on the physical channel" or 3GPP TS 25.221, v · 3 · 2 · 0 "Physical channel and mapping (TDD) of the transmission channel on the physical channel (1 ').

使用於以時間平均分配不同行動終端機之處理及傳輸負 載。時間間隔在該分配被執行上是8 〇毫秒，其與最大傳 輸時間間隔（T T I)有關。將預設DPCH補償值參數加至 R R C移又至UTRAN指揮訊息將引出另外的i 〇個位元（5工2 晶片< 6 0 0階）。如先前所指出，這不是我們所想要的， 因為RRC移交至UTRAN指揮訊息的大小已經接近非分段 GSM空中介面訊息之限制。 因此，我們所需要的及本發明之目的是一種有助於與網 際RAT移交結合移交指揮訊息中額外參數傳輸而不會明 顯加長移交指揮訊息之技術。 發明概要 本發明係關於一種雙模式行動終端機（MT)，其能夠經 由具有第一形式無線存取技術之第一無線存取網路或第丄 形式無線存取技術之第二無線存取網路各自通訊（例如與 一中心網路），且係關於網路及迎合使用者設備單元（u E) 能夠雙模式操作之該網路之節點，且係關於操作該行動終 端機（Μ T )、網路及節點之方法。 當第一典線存取網路服務操作第一節點中之行動終端機 (ΜΤ)時，該行動終端機（ΜΤ)監視來自第二無線存取網 路之傳輸。當身分被授權時，一網路節點準備一無線存取 技術（RAT )移交訊息用於傳輸至設備單元（υ Ε )，結合從 第一無線存取網路至第二無線存取網路之行動終端機 (MT)之移交，且結合從第一模式至第二模式行動終端機 (MT)操作模式之相關改變。在一範例中，非限制實施， -9 - 本纸張尺度適用中國國家標準(CNS) A4规格(210 X 297公釐) 549001 A7It is used to distribute the processing and transmission load of different mobile terminals evenly over time. The time interval at which this allocation is performed is 80 milliseconds, which is related to the maximum transmission time interval (TT). Adding the preset DPCH compensation value parameter to R R C and shifting to the UTRAN command message will lead to another i 0 bits (5-chip 2 chip < 600 order). As pointed out previously, this is not what we want because the size of the RRC handover to UTRAN command message is close to the limit of non-segmented GSM air interface messages. Therefore, what we need and the purpose of the present invention is a technique that facilitates the transfer of additional parameters in the handover command message in conjunction with the Internet RAT handover without significantly lengthening the handover command message. SUMMARY OF THE INVENTION The present invention relates to a dual-mode mobile terminal (MT) capable of passing through a first radio access network having a first form of radio access technology or a second radio access network having a first form of radio access technology. And communication with each other (for example, with a central network), and is related to the network and the nodes that cater to the user equipment unit (u E) capable of dual-mode operation, and is related to the operation of the mobile terminal (MT) , Network, and nodes. When the first line access network service operates a mobile terminal (MT) in the first node, the mobile terminal (MT) monitors transmissions from the second wireless access network. When the identity is authorized, a network node prepares a radio access technology (RAT) handover message for transmission to the equipment unit (υ Ε), combining the first radio access network to the second radio access network. The handover of the mobile terminal (MT) is combined with the related changes in the operation mode of the mobile terminal (MT) from the first mode to the second mode.

Description of the invention (9) Wireless access A first wireless access network 12 with technology and a second wireless access network 14 with a second form of wireless access technology. In the non-limiting example shown in Figure 1, the first radio access network 12 uses GSM radio access technology and the second radio access network 14 uses UTRAN radio access technology. Both the first wireless access network 12 and the second wireless access network 14 are connected to an external core network 16 at the same time. This may be, for example, a public switched telephone network (PSTN) and / or integrated service digital Internet (ISDN). The core network 16 is connected to the first wireless access network 1 2 (such as the GSM wireless access network) through an interface that is an A interface. The first wireless access network i 2 includes one or more base station controllers (BSC) 26GSM, and each base station controller (BSC) 26GSM controls one or more base stations (BTS) 28G. In the example shown in Figure i, the base station controller (BSC) 26GSM is connected to two base stations across the Abis interface, specifically base station (BTS) 28G-i and base station (BTS) 28〇_2 . Each base station (BTS) 280 is depicted in Figure 1 serving three cells C. Each cell C is represented by a circle closest to each base station. Therefore, those skilled in this art will understand that the base station can serve more than one cell for communication across the air interface, and different base stations can serve different numbers of cells.

The rnc node 26u is connected to a plurality of base stations (BS) 28u. For example, and again for the sake of simplicity, two base station nodes, a base station (BS) 28 and a base station (BS) are shown connected to the rnc 2 core through an interface that is an Iub interface. We will again understand that a different number of base stations can be served by an RNC, and that this RNC does not need to serve the same base station. As in the GSM network 12, for simplification purposes, in UTRAN, each base station 28u is shown serving three cells (each of which is at least partially labeled C0.

Any or all mobile terminal internet rat handover function -14- This paper standard applies to Chinese national standards (CNS ) A4 specification (210X 297 mm) 549001 A7 B7 V. Description of the invention (12) 1 0 0, Internet RAT handover trigger function 1 0 2 and RAT handover command message preparation function 1 0 4 can be implemented using individual hardware circuits 'Using software functions in combination with a suitable program digital microprocessor or general purpose computer, application specific integrated circuit (ASIC), and / or one or more digital signal processors (DSP). As mentioned herein, the mobile terminal (MT) 30 has a dual mode functionality, for example, with a first form of wireless access technology network, such as a GS M network 12 and a second form of wireless access technology network. , Such as the UTRAN network 14 communication capabilities. What is illustrated here are their network itself and the nodes in the network that provide the dual-mode mobile terminal service. In its different aspects, the present invention is concerned It is used to prepare, format, transmit, decode and use the unique and concise handover command message as an Internet RAT handover procedure. In order to illustrate this aspect, it is assumed that in the case of FIG. 1, the first wireless access network (GSM network) 12 initially handles wireless communication with the mobile terminal (MT) 30. This could mean, for example, that the first wireless access network (GSM network) 1 2 is now responsible for calling any mobile terminal (MT) 30-related phone (eg, a phone from the core network), or for Deciding whether the mobile terminal (MT) 30 requires the establishment of a telephone connection. Processing communications with the mobile terminal (MT) 30 can also mean that the first wireless access network (GSM network) 1 2 is now overseeing an existing phone associated with the mobile terminal (MT) 30. In addition, it is assumed that the mobile terminal (M Jl) j G has the capability of monitoring / measuring, and the characteristics of a certain channel (such as the # strength) are broadcast by the second wireless access network (UTRAN network) 14. Figure 3 depicts an example Internet rat handover procedure for a representative model of the present invention. 15- This paper size is applicable to the GG family standard (CNS) M specifications (⑽χ tear public love) gutter 549001 A7 B7 5. In the description of the invention (13) Included example basic actions. Figure 3 Actions of the Internet RAT Handover Procedure 3-1 shows a measurement report message transmitted from the mobile terminal (MT) 30 to the base station controller (BSC) 26GSm. The measurement report message is "enhanced" in the induction, which includes not only the measurement (such as signal strength) of the selected channel of the first wireless access network (GS Μ network) 1 2 but also the second wireless access Network (UTRAN network) 1 4 Measurement of the selected channel. The measurement report message is a measurement made and reported based on the signal measurement report function 1 0 1 of the mobile terminal (MT) 30. Figure 3 Action of the Internet RAT handover procedure 3-2 Describes the base station controller (BSC) 26GSM Internet RAT handover trigger function 102, which evaluates the action contained in the measurement report message 3-1 and determines whether an Internet RAT is necessary transfer. When the quality of the wireless connection with the first wireless access network (GSM network) 1 2 downlink, as reported by the action 3-1 measurement report message, falls below a predetermined level, an Internet AT transfer can be initiated . In the scheme shown in FIG. 3, it is assumed that, in action 3-2, the base station controller (BSC) 26GSM internet R a T handover trigger function 1 〇 2 judges that an internet RAT handover is required, for example, an internet ra T handover to hand over the mobile terminal (mt) 30 from the first radio access network (GSM network) 12 to the second radio access network (UTRAN network) 14. For example, if the Internet RAT handover trigger function 1 02 results in action 3-2 judgment, an Internet RAT handover is required. For example, action 3-3 Base Station Controller (BSC) 26gsm prepares and transmits a handover request message to the core network 16. In response, the core network transmits a location change request message to the target RNC (t-RNC), such as action 3 -4. By changing the location request message of action 3 -4, the core network -16-this paper standard is applicable ® g family standard (CNS) A4 specification (21Qχ297 public love) 549001 A7 B7 V. Description of the invention (14) 1 6 The t-RNC is required to reserve resources to accommodate Internet RAT handover. Actual resource reservations are indicated by actions 3-5 in Figure 3. Installation In addition, if action 3-6, t-RNC's RAT handover command message preparation function 104 prepares an Internet RAT handover command message. Figure 4 depicts a non-limiting example format of at least a selected portion of an example internet RAT handover command message generated by t-RNC as actions 3-6. For example, the example Internet RAT handover command message of FIG. 4 includes a universal wireless network temporary identifier (U-RNT1) information element 4-1; a serving wireless network temporary identifier (S-RNT2) information element 4 -2 , Which is part of the information element 4-1; a predefined wireless configuration identification information element 4-3; and a physical channel (PhyCH) information element 4-4. The predefined wireless configuration identification information element 4-3 indicates a predefined configuration of wireless base station, traffic and physical channel parameters for use. The physical channel (PhyCH) information element 4-4 contains a scrambling code number. The service-specific wireless network temporary identifier used in the illustrated embodiment, i.e., S-RNTI2, is a special version of SRNTI previously used in the Internet RAT handover to UTRAN procedure. A smaller range of identification values is used in S-RNTI 2 in order to reduce the number of bits transferred in the Internet RAT. The wireless access technology handover message prepared in actions 3-6 contains a first information element representing the first parameter. The value of the second parameter can be derived from the first parameter, so the second parameter does not need to be included as the Internet. Wireless access technology handovers individual information components in messages. The absence of a second parameter as a separate element in the RAT handover message facilitates non-segmentation of the RAT handover message. -17- This paper size applies the Chinese National Standard (CNS) A4 specification (210 X 297 mm) 549001 A7 B7 V. Description of the invention (1S) In detail, in the description, the wireless access technology transfer message is a The RRC handover to the UTRAN message, the second parameter of the RRC handover to the UTRAN message is prepared, so it can be derived by the mobile terminal (MT) 30 from the first parameter of the RRC handover to the UTRAN message. As shown in FIG. 4, the first parameter is the serving wireless network temporary identifier (S-RNTI 2) of the information element 4-2, and the second parameter is helpful for load distribution and Information components for traffic transmission (for example, the default DPCH compensation value). In an example application, the second parameter (P 2, for example, a preset DPCH compensation value) is derived from the first parameter, using the formula P2 = (PI mod C1) * C2, where Cl is the first constant and C2 is the second constant. In a special example of FDD, the value of C 1 may be, for example, 5 9 or 6 0 0, and the value of C 2 may be, for example, 5 1 2. In a special example of TDD, the value of C 1 may be, for example, 7 and the value of C 2 may be, for example, 1. The handover command message prepared as actions 3-6 is included in the replacement location request confirmation message transmitted by core network 16 as actions 3-7. The Replacement Location Request Confirmation message for actions 3-7 is therefore used to confirm that the resources are reserved by t-RNC and contains details of the UTRA radio resources that will be used after the Internet RA T handover. According to the confirmation of the request to change the location of actions 3-7, the core network 16 then transmits a GSM handover command message to the base station controller (BSC) 26 as described in actions 3-8. The GSM commands the performance of the Internet RAT handover. The GSM handover command message contains details of the UTRA radio resources used after the handover, because the GSM handover command message essentially contains the RRC handover to UTRAN command message as prepared in actions 3-6. -18- This paper size applies to China National Standard (CNS) A4 (210X297 mm) binding line 549001 A7 B7 V. Description of the invention (16) If action 3-9, base station controller (BSC) 26GSM transfer in action 3 -8 The received GSM handover command message passes through the air interface to the mobile terminal (MT) 30. Advantageously, in the technical viewpoint of the present invention, the RRC handover to UTRAN command message of the present invention is suitable to be placed in the GSM handover command message, which need not be segmented through the GSM air interface. Therefore, actions 3-9 include the transmission of GSM handover command messages to the mobile terminal (MT) 30 via the GSM air interface. The transfer command message of action 3.9 contains the RRC transfer to UTRAN command message generated by action 3-6. The action 3-10 of the internet RAT handover procedure in Fig. 3 shows the mobile terminal internet handover function of the mobile terminal (MT) 30 that processes the handover command message. Different actions included in actions 3-10 and performed by the mobile terminal are described in 3GPP TS 25.33 1 v3.7.0 (2001-06), the third generation partnership project; technical specifications group wireless access network Road; RRC Agreement Specification (published in 1999), which is incorporated herein by reference in its entirety. Among these actions are stored certain parameters transmitted in Action 3-9 Handover Command message; initial variables, counters and timers; and (depending on the mode) initial wireless carrier and transfer channel configuration. As in the processing part of action 3-10, the mobile terminal's Internet RAT handover function 1 0 0 automatically makes 3-9 handover command values contained in the S-RNTI 2 parameter to derive or calculate the preset DPCH compensation value to be used by the mobile terminal ( MT) 30 is used in UTRAN. In the implementation of the illustrated example, the preset DPCH compensation value is calculated from S-RNTI2 using Equation 1 provided above. When the wireless access network 14 detects the mobile terminal 30, the wireless access network 14 knows that the mobile terminal 30 has completed from the first network (GSM network-19-this paper standard applies to China National Standard (CNS) A4 specification (210X297 mm) gutter 549001 A7 B7 5. Invention description (1.7) 1 2) Switch to or transfer to the second network (UTRAN network 1 4). Therefore, as in action 3-11, the t-RNC transmits a location change detection message to the core network 16. This instruction can be used for the initial release of resources related to the old network. According to the successful completion of the Internet RAT handover, such as actions 3-12, the mobile terminal (MT) 30 also transmits a handover to UTRAN completion message, through the air interface, to the t-RNC. In response, as in action 3-13, the t-RNC transmits a position change detection message to the core network 16. According to the change of action 3-13, the reception of the message is completed, and the core network recognizes the release of the GSM wireless connection. The release of the GSM wireless connection is transmitted as 3-1 4 from the core network 16 to the base station controller (BSC). The GSM clear command is known, followed by the action 3-1 5 from the base station controller (BSC). ) 26GSM clearing message transmitted to the core network 16. Therefore, when the condition is authorized, the network node of the second wireless access network prepares a radio access technology (RAT) handover message for transmission to the mobile terminal and from the first wireless access network to the second wireless storage. The mobile terminal that takes the network is handed over and used to change the mobile terminal (MT) from the first mode to the second mode operation mode. As described above, as in the present invention, instead of including the second parameter in the handover command message, a rule / algorithm is defined to judge the value of the second parameter from the first parameter included in the handover command message (excluding the Handover of independent information components in the command message). In the description scenario, the preset DPCH compensation value is related to the SRNTI 2 parameter. The SRNTI 2 parameter is usually included in the RRC handover to the UTRAN command message. -20- This paper size applies to Chinese National Standard (CNS) A4 (210 X 297 mm) binding line 549001 A7 B7 V. Description of the invention (18) SRNTI 2 is a suitable parameter, which is deduced from this to include The second parameter, because the SRNTI 2 parameter is an information element, no further role is associated here. That is, SRNTI 2 is just an identity, and its value can generally be arbitrarily specified without any impact, for example, on the performance of mobile terminals or system performance or other similar things. Therefore, SRNI 2 is suitable for combining the second parameter, such as the preset DPCH compensation value, and can be dispatched to allow load distribution to enter the account without any side effects. The solution of the present invention makes it possible to distribute load uniformly from UTRAN by assigning SRNTI 2 accordingly. However, if a smaller portion of the load is generated by a mobile terminal that has been handed over from GSM, then when assigning the SRNTI 2 parameters, UTRAN may not need to include the load distribution in the account. Advantageously, the present invention makes it possible to distribute loads and transmissions for different mobile terminals without increasing the size of handover command messages (such as RRC handover to UTRAN command messages). Therefore, it is possible to transfer the handover command message of the present invention within a non-segmented GSM air interface. Beneficially, it will not abandon the effectiveness of the Internet RT transfer. The invention simultaneously applies the UTRA-FDD and UTRA-TDD modes of the UTRAN standard such as the 3rd Generation Partnership Project (3GPP). Although the description of the present invention has been considered in connection with the most practical and optimal embodiment, we will understand that the present invention is not limited to the embodiment of the invention, but on the contrary, it is intended to cover various modifications and Equivalent configurations are included in the spirit and scope of the scope of additional patent applications. -21-This paper size applies to China National Standard (CNS) A4 (210X 297mm) binding line
