Description of the Invention: TECHNICAL FIELD OF THE INVENTION The present invention generally relates to wireless communication systems. More specifically, the present invention relates to power management in a unified wireless transmit/receive unit (WTRU) capable of operating over a variety of radio access technologies (RATs). [Prior Art] A unified WTRU is a mobile device capable of communicating via a variety of radio access technologies (RATs). Integrated WTRUs provide a rich set of services, including voice, mobile access to email and personal information, website browsing, audio and video replay and streaming, gaming, and more. However, communication via multiple RATs requires a lot of power, resulting in a rapid drain on the integrated WTRU battery. In a unified WTRU, communication via multiple RATs requires a unified WTRU to transmit and receive in each of a variety of RATs. To further address this problem, a unified WTRU may have multiple RF keys or be able to communicate via multiple RATs simultaneously. Since integrated WTRUs are typically portable devices, it is undesirable to meet the demand for power by increasing the size of the battery. Therefore, minimizing the consumption of power in a unified WTRU is desirable. Of all the elements in a unified WTRU, the transceiver typically consumes the most amount of power. Therefore, the easiest way to conserve power is to turn it off or reduce its activity when the transceiver is not needed. This can be achieved by placing the WTRU in a sleep state or discontinuous reception (DRX) mode. Different radio access technologies (RATs) have their own power saving mechanisms, and generally consider the above two states (sometimes using different terms from below). The first state is an awake state when the WTRU's radio is turned on. In this state, the WTRU may actively transmit or receive data, or the WTRu may be in a power saving mode, which generates traffic for the rib monitoring radio, and if needed, it quickly switches to the data and receives the second state to sleep. The WTRU's radio was hired by Lai Xinxia U to intermittently wake up to receive information from the network. For example, the beacon in EEE8〇2 11RAT, in the third generation partner program (3Gpp;) j^T Pilot channel (PCH), etc. The network can save the packets destined to sleep in the buffer' and send the packets when the WTRU is awake. It should be noted that the RAT protocol defines the required and optional power management modes for a given technology. To illustrate, in the wireless local area network (DAN), in order to reduce the battery consumption of the wireless client, the client radio will alternate between two states, including: (1) an active state during which the wireless client continuously transmits And receiving:; and (2) a power saving state that occurs when the wireless client is intermittently sleeping. The WLAN access point in the infrastructure network tracks the status of each associated WTRU, which buffers the traffic directed to the WTRU in a dormant state. At a fixed time interval, the AP will send a TIM (Traffic Indication Map) message indicating which of the dormant WTRUs buffered traffic waiting at the access point. The WTRU in a dormant state will intermittently start its receiver and receive the TIM. If the WTRU has a waiting flow' then it will send a Packet Switched (PS) poll frame to the AP. The WTRU will wait for traffic 'until it is received, or the AP will send another TIM ΊΗ» box to indicate that there is no buffered traffic. In Global System for Mobile Telecommunications (UMTS) technology, a WTRU may be in either of two basic states: an idle state or a connected state. In the idle state, the WTRU is "in the cell," however, the WTRU is still able to receive signaling information, such as paging. The WTRU will wait in an idle state until a radio resource controller (r^C) connection is established. Various connection state modes are defined in UMTS, including cell-specific channel (CELL-DCH), cell forward access channel (CELL-FACH), cell phone channel (CELL-PCH), and UMTS terrestrial radio access. The network (UTRAN) registers area paging channels (URA-pCH), each of which has variable amplitude communication functions and power saving effects. Other access technologies have their own respective power management states and modes. The UMT power mode is merely exemplary and does not represent a limitation on the scope of the present invention, which can be applied to any desired radio access technology. Referring to Figure 1, the prior art integration is shown in a multi-RAT wireless environment. WTRU 110 » Each RAT (RATI, RAT2, ..., RANN) can be used for communication via their respective protocols. The integration ... Ding fat 11() includes multiple communications for each RAT, RAT2, ..., RANn, respectively. The RAT processes the early elements 120, 12, 2. The power states of each RAT processing unit 12 (^, 12〇2, ... 120N are controlled by the respective RAT battery management units 130, 1302, ..., 130N. These rat battery management Units 13〇1, 13〇2, ...130N; manage power and resources according to their respective RAT protocols. Thus 'tegral WTRU 110 includes functionality 1364918 to communicate over multiple RATs - and according to each RAT protocol and power mode To manage power and resource functions. Other WTRU elements 140 include various other components and functions, including displays, input devices, transmitters, etc. To illustrate, when integrated

The multi-raT wireless communication environment includes: RATi, RAT2, ... RATN (by way of example) These may be, but are not limited to, the scope of the present invention), integrated packet radio service technology (GPRS) network 'Universal Mobile Telecommunications (UMTS) network, Global System for Mobile Communications (GSM) network' GSM enhanced data rate GSM evolution ( EDGE) Wireless Access Network (GERAN) and Wireless Local Area Network (WLAN), such as the IEEE 802.1 lx compatible network. The integrated WTRU 210® includes other WTRU elements 250' which may include transceivers, memory, displays, etc. CMRBM Unit 220 Each RAT battery management unit 24 of the integrated WTRU 210 (h, 24〇2, ... 24〇n. To achieve this, three general power states are preferably used by the CMRBM unit 220. The first power state is the awake state. In the awake state, the integrated WTRU 210 actively transmits and/or receives data. The CMRBM awake state is similar to the WLAN start state and the UMTS connection state described above. The second power state is the sleep state. In the sleep state, the RAT is to reduce functionality and The mode of reducing power consumption operates, typically only periodically. The sleep power state is similar to the UMTS idle state described above. The third power state is the off state. In the off state, the RAT is completely powered off and not periodically transmitted or Receiving communication. Referring to Figure 3, the state machine 300 used by the CMRBM unit 220 of the integrated WTRU 210 for controlling the RAT battery management unit is shown. In the closed state 310, the given rat processing is completely turned off. In the open state 320, a given RAT processing unit is started, and at least the RAT processing unit is partially operational. The startup state 32〇 also includes The awake mode 330 and the sleep mode 340. In the awake mode 330, the RAT processing unit is fully operational 'and can even actively send data to or receive data from the network. In the sleep mode 340, the RAT processing unit functions to reduce functionality. Operating in a sexual manner. Typically, in sleep mode 340, as described above, the RAT processing unit will periodically turn off its transceiver and reduce control message transmission. It should be noted that the CMRBM unit 220 power state is a general power state that is used when adjusting multi-RAT battery management. A given _ agreement can define multiple sub-states or patterns for a given CMRBM power state. For example, the start state in UMTS access technology includes at least four sub-states (URA-PCH, CELL_DCH, CELL-PCH, and CELL-FACH as described above). When the CMRBM unit 220 normally regulates battery management, the particular sub-state selected by the RAT battery management unit is ultimately determined by the RAT battery management unit in accordance with its respective RAT agreement. This is not limited to wake-up mode 330' and includes CMRBM sleep mode 340' and various other power management details specific to each rat protocol. 1364918 Still referring to Figure 3, the state change is indicated by a dashed line. The RAT battery management unit can change from the off state 310 to the on state 320 by receiving a state change request, and vice versa. In the on state, the rat battery management unit can select between the awake mode 330 and the sleep mode 340 by way of a state change request. Alternatively, the rat battery management unit can unilaterally change its state or mode based on its respective RAT protocol and battery management structure. Referring again to Figure 2, the CMRBM unit 220 preferably communicates with the respective RAT battery management units 240, 24, 2, ... 240N of the integrated WTRU 210 by the detailed transport message primitives of the examples in Table i below. Other primitives may also be used and the primitives discussed below may include other additional information elements other than those explicitly recited in the specification as needed. Table 1 Primitive Direction Description State change CMRBM Single CMRBM unit request RAT battery management unit Change request -------. Yuan 1 RAT battery management unit Change the power status. It should be noted that the RAT Battery Management Unit is finally executed to execute the request. For example, in a UMTS RAT, the WTRU cannot automatically enter a sleep state; this is a network decision. If there is a substate, it also indicates the substate. State Change The CMRBM Single RAT Battery Management Unit indicates whether its status changes indicator - the RAT battery management unit changes. The status change may be the result of a status change request from the CMRBM unit, or the 11-state status CMRBM single message request element initiated by the RAT battery management unit based on the RAT protocol <-RAT power ------ pool management unit status CMRBM single message response element - RAT power --- pool management unit open please CMRBM single request element - RAT battery management unit off please CMRBM single request yuan one RAT battery management unit configuration report CMRBM single caller - RAT battery management unit configuration please CMRBM single request element - 'RAT battery management unit automatic status change. Indicate this new status in the message. Before the RAT battery management unit automatically enters the new state, it requests confirmation of the status change from the CMRBM unit. Indicate the new status in the message. In response to the status information request, the CMRBM unit responds by indicating the status of the acknowledgment. It should be noted that the final state decision depends on the RAT battery management unit. The RAT battery management unit preferably notifies the CMRBM unit of the selected state by a status change indication message. The command causes the CMRBM unit to turn on the RAT battery management unit and then turn on the RAT processing list to cause the CMRBM unit to turn off the RAT battery management unit' and then turn off the RAT processing unit 0 RAT battery management unit to provide internal configuration parameters related to its current power state to CMRBM unit. The CMRBM unit uses its primitives to customize the power state parameters of the rat, resulting in the best power consumption. Figure 4 is a flow diagram 400 of a method for adjusting multi-rat 12 1364918 'battery management in the integrated WTRU of Figure 2; CMRBM unit 220 monitors each RAT battery management unit included in the unified WTRU 210 2401, 2402, ... 240N and RAT various signal and link metrics (step 41). Based on this monitoring, the CMRBM unit 220 determines whether it is desired to make a state change or mode change to any of the ht battery management units (step 42A). This determination may be based on any of the principles used to minimize the battery power of the integrated WTRU 220. For example, when there is no available network for a given RAT (e.g., RAT), it is desirable to place the corresponding RAT battery management unit 230 and RAT processing unit 240! in an off mode to conserve energy. Likewise, if the network becomes available, then the RAT battery management unit 23 and the RAT processing unit 240 can be placed in an on state. Alternatively, when the integrated WTRU 21 〇 senses a lower power level, the predetermined RAT processing unit may be placed in an off mode permanently or periodically to conserve battery power. Alternatively, the user of the integrated WTRU 210 can configure the CMRBM unit 220' to adjust the power mode and status as needed. Alternatively, the CMRBM unit 22 may request that the state of the RAT battery management unit 230 be changed from the sleep mode to the awake mode, or when it is about to switch to it, it rejects the RAT battery management unit 230 based on its respective power management agreement to change to Sleep mode, the link quality metrics that may be utilized to affect the state change of either RAT will be described in more detail below with respect to FIG. For example, when the WTRU 21 is connected to multiple RATs and the quality of the links on these RATs is good, the CMRBM may request that rat change its state to sleep mode' or vice versa. In the case where the CMRBM unit 220 determines that the state change 13 1364918 - or the mode change is required in step 420, the CMRBM unit 220 requests the RAT battery management unit 230 to perform a state change or mode change (step 43 〇) «> preferably , CMRB1V [unit 220 requests a state change using the primitive defined in Table 1 above. Specifically, the CMRBM unit 220 transmits a "state change request" message to the RAT battery management unit 230 that is requested to change the state or mode. Upon receiving the state change request, the RAT battery management unit 230 indicates that it will comply based on its RAT-specific agreement. The request, and preferably a "status•change indication" message is sent to confirm its current status (step 440). It should be noted that 'when a particular RAT changes mode (eg, from awake mode to sleep mode, or vice versa), typically In this way, the network is notified of this mode change or state change' so that the traffic directed to the integrated WTRU 210 can be buffered over the network, as described above, or for other reasons. Utilizing the RAT that synchronizes the power mode with the network A specific agreement to implement the process. If the CMRBM unit 220 does not expect a state change at step 420, then it is determined whether any of the battery management units 230 desire a state change (step 450). The 〇RAT battery management unit 230 can make based on the RAT specific agreement. Independent judgment about this state. If there is no battery management unit 23, the desired state changes, the party The method returns to the step for further monitoring. If the RAT battery management unit 230 desires a state change, the rat battery management unit 230 requests permission from the CMRBM unit 220 for a state change (step 460). Preferably, as described in Table! , the request is a status information request "primitive." Upon receiving the status change request, the CMRBM unit 220 determines whether to permit the status change request and accordingly signals the requested RAT battery management unit 23 (step 470). 14 1364918 Preferably, the CMRBM unit 220 signals the requested RAT battery management unit 230 using the "state resource response" message as in Table 1 above. It is contemplated that the CMRBM unit 220 may or may not permit the requested state change, and the requested RAT battery management unit 230 may continue with the state change regardless of the permission or rejection permitted by the CMRBM unit 220. In another embodiment, referring to FIG. 5, a flow diagram 500 is shown for using a configuration report to adjust multi-RAT battery management in the integrated WTRU 210. When the integrated WTRU 210 is turned on (step 510), each RAT battery management unit 230 notifies the CMRBM unit 220 of its respective battery management configuration (step 520). Preferably, the 'RAT battery management unit 230 transmits a "Configuration Report" message as defined in Table 1 above to the CMRBM unit 220. It should be noted that the initial battery management configuration is typically specified by a particular RAT agreement. Next, CMRB1V [unit 220 compiles the report and determines if any RAT battery management unit 230 needs to be requested to make a state change, thereby minimizing energy consumption (step 530 > if CMRBM unit 210 determines that no state change is required (also That is, the integrated wtru 21 is currently operating in the state of optimal power configuration, then the method proceeds to step 550. If, on the other hand, the CMRBM unit 220 determines the desired state change (ie, the 'integrated WTRU 210 may be more efficiently configured) Then, the CMRBM unit 220 § seeks the RAT battery management unit 230 to make a state change (step 540). Preferably, the view is in the form of a "configuration request" message as defined in Table 1 above. Then 'request to change the state. The battery management unit 230 can determine whether to perform a state change according to its own specific RAT agreement. In the next configuration report, the selected state will be indicated by the RAT battery management unit 23. Optionally, each RAT battery management unit 230 periodically Repeat the configuration report (step 550). The periodic report can be performed at regular intervals or can be based on user control or The CMRBM unit 22 is dynamically adjusted. In addition to the methods described with reference to Figures 4 and 5, the CMRBM unit 220 may request the RAT battery management unit 230 to completely turn off the power, thereby turning off its respective RAT processing unit 240. Preferably, This processing is implemented by transmitting a "shutdown request" message as defined in Table 1 above. Similarly, the CMRBM unit 220 can request that the rat battery management unit 230 in the power-off state is turned on. Preferably, by transmitting the above table 1 The process is implemented by a defined "on request" message. The integrated WTRU 210 can power the RAT battery management unit 230 such that the corresponding RAT processing unit 240 is turned "on" or "off" in various situations to conserve power. For example, in the absence of a scan In the case of a network, when the power supply is below a predetermined threshold, or when the user does not use a particular RAT network for a predetermined amount of time, the CMRBM unit 220 may turn off the RAT battery management unit 230 and the corresponding RAT processing unit 240. .

In this embodiment, referring to Fig. 6, the CMRBM unit 220 operates in conjunction with the handover policy function between the RATs of the integrated WTRU 210 to improve the execution of handover between RATs by reducing handover delay. The CMRBM unit 220 of the integrated WTRU 210 monitors each RAT 1364918 battery management list it23G and RAT signal quality and power management metrics (step 610). Based on the handover measurements between the RATs of the integrated WTRU 210, it is determined whether a handover between RATs is desired (step 62). For example, it may be desirable to switch a boot session from a RAT network with a lower or reduced link quality to a RAT network with stronger or improved link quality. When it is determined in step 62 that the desired handover is made, it is then determined if the target RAT processing unit 240 is in the awake state (step 630). If the target rat processing unit is not in the awake state' then the CMRBM unit 220 signals the target rat battery management unit 230 to place the target rat processing unit 24 to the appropriate awake state for handoff (step 640). This can be achieved by referring to the above methods of Figs. 4 and 5 (i.e., each RAT signaling or configuration report). The target RAT processing unit is then in an awake state and the integrated WTRU 21 〇 performs a handover between RATs (step 650). Finally, CMRBM unit 220 signals each RAT battery management unit 230' in integrated WTRU 210 to achieve a minimum power consumption configuration (step 660). For example, when the integrated WTRU 21 is in the active state using the first RAT processing unit 240, but the CMRBM unit 22 detects a decrease in link quality (ie, a predetermined criterion indicating handover), the CMRBM unit 220 requests the second. The RAT battery management unit 2302' or a plurality of other rat battery management units 230^...230 and the corresponding rat processing units 240], 2402, ... 24〇n currently in a sleep state are changed to the awake state.
