Detailed description of the preferred embodiment The wireless system communication restoration method according to an embodiment provides information on neighboring cells and / or zones that can be used and can be used to restore a mobile station that may lose communication links. Each call recoverable base station has a preset forward call recovery frequency -6-This paper size is applicable to the Chinese National Standard (CNS) A4 specification (210X 297 mm) 1235614 A7 B7 5. Description of the invention (4) channel, by the predetermined code Identify. In another embodiment, each adjacent configuration has more than one preset forward call recovery channel and the mobile station uses IMSI (International Mobile Station Identification), TIMSI (Temporary International Mobile Station Identification), ESN (electronic serial number), system time or The combined chaos function determines the channels that receive and transmit from each recoverable base station. The mobile station can then use this channel to receive signals before the base station was restored. When the mobile station approaches the base station, the previous information can be used to instruct the mobile station to combine the power control sub-channels from multiple adjacent recovery base stations. This may happen when the mobile station moves into the coverage area of the base station and the mobile station is in an idle state, that is, there is no continuous communication link, the channel information from the beginning of the call, or the change of the mobile station's role set. The wireless communication system 10 illustrated in FIG. 1 has a plurality of cells 12, 14, 16, 18, 20, 22, 24. Cells 12, 14, 16, 18, 20, 22, 24 communicate with the BSC 26 via a radio air interface. Cells 12, 14, 16, 18, 20, 22, 24 each have corresponding adjacent groups that form cells in a geographic and / or transport environment. For example, the adjacent group of cells 18 includes cells 12, 14, 16, 20, 22, 24. In a TIA / EIA / IS-95 mobile station-base station compatible standard such as a dual-mode broadband spread spectrum cellular system (hereinafter referred to as the IS-95 standard), or the TIA / EIA / IS-2000 of the cdma2000 spread spectrum system In the spread spectrum transmission system of the code division multiple acquisition (CDMA) system specified by the standard (hereinafter referred to as the cdma2000 standard), the spread spectrum signals have the same bandwidth, and each signal has its own difference. Column. The operation of the CDMA system is assigned to US Patent No. 4,901,307 entitled "SPREAD SPECTRUM MULTIPLE ACCESS COMMUNICATION SYSTEM USING SATELLITE OR TERRESTRIAL REPEATERS," and US Patent No. 5,103,459 entitled to the assignee of this patent application. Paper size applies Chinese National Standard (CNS) A4 specification (210 x 297 mm) 1235614 A7 B7 _ V. Description of invention (5) "SYSTEM AND METHOD FOR GENERATING WAVEFORMS IN A CDMA CELLULAR TELEPHONE SYSTEM" Reference. In this way, multiple users send messages at the same bandwidth at the same time. Fig. 2 illustrates a part of the system 10 of Fig. 1, which includes the communication between the base station 32 labeled MS1 and MS 38. BS1 32 is in cell 18 of Fig. 1. The other two base stations 34, 36, labeled BS2 and BS3, are in cells 16, 24, respectively. The radio air interface provides forward links (FL) from BS1 32 to MS 38 and reverse directions from MS 38 to BS1 32 Link (RL) communication medium. It is necessary to know that MS 38 can move in the system 10 to degrade the signal quality to and from BS1 32. When the call starts, MS 38 sends out the transmission in the incoming channel. BS1 32, BS2 34 And BS3 36 sends channel configuration information on the calling channel. The channel configuration identifies the Walsh code index of each base station. The signal quality is usually measured by the signal-to-noise ratio (SNR) and can lead the signal energy (Ec) to each chip of the total received power density / I〇). Figure 3 illustrates the signal quality of BS1 32 and BS2 34 measured at MS 38. The signal quality of BS2 34 starts to increase at time t0 and continues to increase to the critical level labeled D_ADD at time ti The critical level t_add provides a reference signal quality above which instructs the MS 38 to notify the base station to add a base station to its active group (AS). The AS is formed by the base station transmitting and receiving communication with the MS 38. AS Usually selected from base stations in the selected group (CS). CS includes base stations that can communicate with the MS 38. CS is usually selected from base stations in the neighboring group (NS). Continue to see Figure 3, when the signal quality of BS2 34 is improved The signal quality of BS1 32 is degraded. The increase of the signal energy level received from BS2 34 increases the signal degradation of BS1 32, because the signal quality of a given base station is this base station letter -8-This paper standard applies to Chinese national standards ( CNS) A4 size (210X297 male ) 1235614 A7 B7 V. invention is described in all the comparisons No. (6) and the energy of other signals. At time t1, the MS 38 measures the BS2 34 signal energy above T_ADD. This means that MS 38 needs to take appropriate action to trigger a change of hand. At time t2, MS 38 transmits a Leading Strength Measurement Message (PSMM) with BS1 32 and BS2 34 measurement information to BS1 32 and BSC 26. At time t3, BSC 26 sets the MS 38 link from BSC 26 to BS2 34. The BSC 26 has a selector. Compared with MS 38, the communication link set by BSC 26 forms a circuitous communication network between BS1 32, BS2 34 and BSC 26. At time t4, BS1 32 sends a handover direction message (HDM), which includes the BS1 32 and BS2 34 and BS1 32 and BS2 34 forward link (FL) channel correlation code indices. This information enables the MS 38 to receive and demodulate signals from BS1 32 and BS2 34. At time t5, the MS 38 receives the HDM from BS1 32 and demodulates the signal from BS2 34 outside BS1 32. In this example, only a new base station is involved in the handover. However, the handover situation can involve any number of base stations, and these base stations communicating with MS 3 8 form an AS. When the MS 38 receives signals containing symbols from multiple base stations in the AS, the MS 38 can combine these signals to obtain a stronger signal. This combination process is called soft combination of FL and is often performed in combination with the best ratio, which is based on the weight of signal quality. At time t6, the MS 38 sends a transfer completion message (HCM) that acknowledges the HDM received from the BS1 32 or indicates successful completion of the transfer. Referring again to FIG. 3, it may happen that the signal quality of the BS2 34 increases too quickly. In this case, the signal strength of BS2 34 relative to BS1 32 causes the signal quality of BS1 32 to deteriorate. This prevents the MS 38 from communicating with the infrastructure until it receives the necessary information to identify the BS2 34 or BS2 34 to shift the pseudo-random noise (PN) required by the channel used by the MS 38. -9-This paper size is in accordance with Chinese National Standard (CNS) A4 (210 X 297 mm) 1235614

I platform coverage area, changing hands can prevent communication link from missing. After the software changes hands, the mobile station maintains connection with two or more base stations at the same time. The position of the mobile station can be regarded as the source cell, and the mobile station can move to the next cell: it is the target cell. The mobile station uses a separate multipath type receiver to demodulate multiple signals received by the FLs of multiple base stations. The two signals are combined to obtain a composite signal of improved quality. Each base station related to the soft handover separately demodulates the received signal, and each sends demodulation and decoding information to the BSC. Bsc has a selector to select the best box from the boxes received. For various conditions and system requirements, other types of resale can be used. Measure the signal quality of multiple base station FL leading signals at a mobile assisted handover (MAHO) mobile station. This information is reported to the source base station. This signal quality is compared with various thresholds to decide whether to add a base station to the AS. If the quality of the established pilot signal is greater than the critical detection threshold T_ADD, add the pilot in the AS. In an alternative embodiment, the lead may be added to the CS before AS. As a result, the threshold changes the base station status. When the negotiation cannot be rescheduled, the mobile station information is provided in advance. Call recovery is initiated in various situations. In normal operation, the mobile station and base station use triggers to determine appropriate operations. For example, a mobile station operating in the system 10 uses multiple thresholds to decide to report base station information. A critical point is that the above-mentioned T-ADD indicates the signal quality level of the AS Likou base station. When the mobile station receives the signal on T-ADD, the mobile station moves this base station to cs, increases the number of times to search for this base station 'and reports this condition to the system from the existing AS. Another critical T-DROP makes the base station below the signal quality level -10-^ Paper size is 3 medium ® ® Family Standard (CNS) A4 specification (210X297 mm) 1235614 A7 ------- -One B7 5. Invention description (8) " --- The signal received by the Tian mobile station exceeds T-TDROP during T-DROP (Next, the mobile station reports this condition to the system from the existing AS. In each The base station in the situation sends this information to the base station controller. Seek any possible trigger at the base station of the Tongju Recovery AS. In the first case, the original trigger occurs when the FL signal quality is at a critical level. Patriarch-Critical Length. This trigger involves receiving a power control (pc) request from the mobile station at the base station to increase the transmission level of the base station. The base station has often been sent to the mobile station at the maximum power level. For example, the FL traffic transmission dimension $ is at a high level in the pre-sufficient time. The mobile station can choose many requirements to increase the power, that is, the UP command. The mobile station can report a lot of deletions instead. Determining that there is a desired value, delete occurs. Transmission in another 'mobile station' The base station is informed that its external loop setting is very south 'or at its maximum allowable level or too long at these levels. The second trigger occurs when a specific response is expected from the mobile station, but no response is received or received. Different responses. This trigger involves the mobile station not accepting the message sent by the base station. The message can be resent a predetermined number of times before the trigger is implemented. This predetermined number of times can be fixed or variable and can change with the air. Similar The local base station can receive repeated RL messages from the mobile station that need to be acknowledged, and the message is received after the base station transmits the acknowledgement. The third trigger is related to the low quality of the reverse link, such as when the frame error rate (FER ) At the critical level. Rl can replace a predetermined period of time at a high level. There are still other situations that can have a high RL set value. The base station added to the AS also has a call recovery trigger that initiates a recovery function. The most important trigger is the BSC Inform the established mobile station that there may be a problem. At this time, the base station starts to search from this -11-This paper size applies the Chinese National Standard (CNS) A4 specification (210 X 297 mm) 1235614 A7 B7 Explanation (9) The signal of the mobile station. The mobile station can also use a variety of call recovery triggers to enter the call recovery. The first trigger occurs when there is an abnormal error in the received signal. For example, the erase of FL in a mobile window may exceed a predetermined threshold Level. In one embodiment, the critical level is that 12 consecutive frames are deleted. In this case, the mobile station will turn off the transmitter part of the mobile station and can restart the transmitter when at least two FL consecutive frames are not deleted. The two types of mobile station recovery triggers occur when the mobile station receives a PC command from the base station to increase power. The base station may have difficulty receiving the RL signal because the mobile station has a large amount of path loss. The third type of recovery trigger occurs when one or more rl messages require approval by the base station to be acknowledged. This is considered a resend retry trigger. Similarly, the base station may respond inappropriately or not to mobile station messages. A similar trigger type occurs after the mobile station actually transmits the acknowledgement and receives a repeated FL message from the requester. The four types of recovery triggers occur when the mobile station transmits at a high level during a predetermined period. It is assumed in this case that the RL does not pass through the base station with sufficient energy. In one embodiment, a flexible threshold is implemented for one or more of these call recovery triggers. Call recovery triggers can be transmitted in system 10 based on multiple attempts. + This attempt is often made at the bond layer between the signal and the physical bond. This chain = layer layer 2 is discussed below with reference to FIG. 8. The recovery procedure is performed at the recoverable H ... MS 38 of the system 10 as shown in Fig. 1 so that the communication link is decomposed when the communication link such as Fl deteriorates.

Examples such as RL <repeat number of transmissions or time between consecutive deletions or MS 38 transmitter prohibition can respond to the system 10 infrastructure such as muscle 32 and / or I% =. In-Alternative embodiments define fixed parameters for a specific role, such as a specific maximum number of resends. In another embodiment, the movement condition and / or location provides a trigger. The MS 38 current transmission level near the predetermined maximum can trigger a call recovery. Other triggers include the deletion of the measurement of H with the current AS transmission, the inadequacy of the inner loop power control, and the MS 38's main role and the inner loop are different. There are still other embodiments that can be combined with specific data and movement conditions as triggers. The basic architecture of the system 10 can provide MS 38 operation type information to help determine the call recovery trigger threshold, and use this information to select fixed parameters for the MS 38 as the trigger threshold. In one embodiment, the general number of call retries is problematic or abandoned. An alternative embodiment uses the RL load to set and adjust the threshold. There are also alternative embodiments that can utilize the partitioning of the MS 38 location in the system 10 as a predetermined cell. Still other embodiments take into account the time of day and / or day of the week related to the established mobile traffic pattern. Any combination of these architectures can also be implemented as applicable or needed. In the system 10 of Figs. 1 and 2, each base station 32, 34, 36 transmits the previous information to the mobile station with which it communicates. Information prior to BS 32, 34, 36 each contains a separate proximity list. The neighbor list identifies the corresponding pseudo-random noise (PN) code offsets of the neighbors. Referring to FIG. 4, the BSC 26 responds to any kind of trigger using a set and a circuitous connection between BS1 32 and BS2 34. According to an embodiment, the method of call recovery 100 -13-This paper size applies the Chinese National Standard (CNS) A4 specification (210 X 297 mm) 1235614 A7 ___ B7_ ΐ Description of the invention (11) ~~ ^ See Figure 6 Instructions start. FIG. 5 illustrates an example of specific signal quality leadership. In this example, having time to identify the MS 38 may be problematic. 6A and 6B illustrate a call recovery method 100 according to an embodiment. In step 102, the BS1 32 sends the preset channel configuration of the adjacent base station group to the MS 38. The base station of the adjacent group is a recoverable unit having the software and / or hardware required to implement call recovery, and the base station coverage area with the coverage area and the neighbor group overlaps. The default channel configuration index used to identify the base station in the adjacent group includes the BS2 34 code. The base stations in the adjacent group can be restored, and have a preset spread code to identify the mobile stations that need to be restored by calling. An embodiment code is a special Walsh code. In step 104, BS2 34 sends a resend trigger to MS 38. Resend Retry Trigger specifies the number of retries that ms 38 can have before the call resume operation begins. BS1 32 then decides at decision block 106 whether a reset trigger has occurred. If no recovery trigger has occurred, processing waits for the trigger to occur. When a trigger occurs, processing continues at step 108, instructing all base stations in the NS of BS1 32 and MS 38 to transmit on individual preset channels. It should be known that some base stations in Ns may not be able to establish a communication link because the FL or RL is too weak, but each base station in NS starts transmitting to ms 38. Multiple transmission provides a stronger FL signal from MS 38 and a more reliable RL from BSC 26. It should be understood that according to this embodiment, the number of retries of RL messages or the number of consecutive deletions of storage is determined by BSC 26 and provided by the radio link messages and broadcasts to MS 38. In an alternative embodiment, fixed parameters which are different from other parameters are used. An embodiment incorporates a mobile station status function. The movement can be regarded as the closeness between the actual transmission level and the maximum transmission level of the MS 38. Similarly, the quality of FL is also considered in the mobile situation, such as the deletion of the current AS. There are other -14-This paper size applies Chinese National Standard (CNS) A4 specification (210 X 297 mm) 1235614 A7 B7 V. Description of the invention (12) The internal circuit is insufficient due to the movement conditions. Insufficient internal loop is the difference between the target SNR and the Snr sent by the internal loop PC. Another embodiment combines movement conditions and transmission types. The allowable weight can be adjusted according to the statistics related to the interrupted call or problem call. For example, there can be an average number of retries above which most problems cannot be recovered. Other considerations include RL payload, MS 38 location and / or time or date. In the latter case, the specific mobile traffic pattern affects the number of mobile stations that need fast call recovery. Continuing with step 11 of FIG. 6A, the BSC 26 determines the current AS of the MS. The BSC 26 then starts the hdm timer in step 112 and transmits the HDM in step 114. At this time, the system wants to remove the communication link of the preset channel. The preset channels can be used by any mobile station in the system 10, thus optimizing the use. When the MS 38 uses a preset channel, the channel will not be available for other mobile stations. Instruct NS base station and preset channel transmissions to start transmission on alternate or new channels in parallel. This is the beginning of a change of hand. If the MS 38 message received at decision block 118 BSC 26 indicates that the handover is complete, proceed to step 120 to terminate the communication link between the MS 38 and the NS member on the preset channel. Processing continues at step 124. Conversely, if no handover completion message is received, the BSC 26 checks at decision block 122 whether the HDM timer has expired. If the HDM timer expires, the appropriate preset channel is aborted and transmitted to the MS 38, the call resume is canceled at step 124 and the use of the preset channel and the new channel is aborted at step 125. Normal operation resumes at step 126. If the timer has not expired at decision block 122, the process returns to decision block 118 and waits for a handover completion message from MS 38. -15-

Description of invention (15) group. One problem is that the last transmitted PSMM received may be incorrect, in which case the PSMM used to identify the subgroup is incorrect. For example, when the PSMM is finally received to identify BS1 32 and BS3 36, but the MS 38 is not received, and then the PSMM identifying BS1 32 and BS2 34 is sent, the call recovery is blocked. The detour network of BSC 26 settings and BS3 36 and BS3 36 starts to transmit to MS 38 with preset channels. Unfortunately, MS 38 assumes that call recovery communication is established with BS2 34 and is prepared on a different preset channel. The extra transmission of BS3 36 is wasted, and more noise is generated in the system 10. When the MS 38 begins to resume a call, a timer can be used to delay the start of the call after the call triggers. The timer period can be set by BSC 26. When the timer expires, the MS 38 transmits the preface on the RL lead channel. The preface contains a call recovery message. The preamble in one embodiment is a predetermined constant, which can be set by the BSC 26. In an alternative embodiment, the preamble is a variable of length determined by the system operator. After the preamble was transmitted, MS 38 sent a message about the FL change. This message can be PSMM. This message can be sent multiple times to ensure that BS2 34 is received. The combination of the above methods can provide various advantages of call recovery. In one embodiment, the call recovery method is based on the radio transmission environment of the source cell base station. When the number of recoverable neighbors is small (such as 2), BSC 26 will instruct all neighbors to transmit on individual preset channels. AS update and MS 38 transmitter startup were not delayed. For larger recoverable proximity groups, BSC 26 will indicate that the proximity follows the signal of MS 38. After waiting for a delay caused by the proximity report to receive a signal from MS 38, instruct those hearing neighbors to use the preset channel. Similarly, if the PSMM of the MS 38 is received within a preset period, the base stations identified by these PSMMs are instructed to use the preset channel. It should be known that when the FL is fixed as a continuous good box-18-This paper size applies the Chinese National Standard (CNS) A4 specification (210 X 297 mm) 1235614 A7 B7 V. Description of the invention (16) Define the appropriate operation by the PC subchannel PC commands transmitted are considered valid. FIG. 8 illustrates the architecture of the wireless communication system 10 of FIG. 1 in a layered architecture. The architecture 700 includes three layers: a signal layer 702, a link layer 704, and a physical layer 706. The signal layer 702 provides an upper layer signal 708, a data service 710, and a sound service 712. The signal layer 702 provides sound, package data, simple circuit data, and synchronous sound and package data services. This layer provides communication protocols and services corresponding to the bottom two layers. The link layer 704 is divided into a link access control (LAC) sublayer 714 and a media access control (MAC) sublayer 716. The application and signal layer 712 protocol utilizes the services provided by the LAC sublayer 714. The link layer 704 serves as a communication protocol and an application interface above the signal layer 702 and the physical layer 706. The MAC sublayer 716 further includes a multiplexing and quality of service (QoS) transport block 722. The link layer 704 couples the signal layer 702 and the physical layer 706. The physical layer 706 is formed by a transport physical channel 724. FIG. 9 illustrates a system 10 and operation timing of FIG. 1 according to an embodiment. Refer to Figures 6A, 6B, and 7. The horizontal axis represents time and the vertical axis represents the channel used for transmission. The source cell base station BS 1 32 is in the middle, and the information is sent to the MS 38 by the channel. Explain the two channels of MS 38: transmit channel Tx and receive channel Rx. Explain the two situations of receiving channels: Rxi and Rx2. The adjacent base station of base station BS2 34 is also described for the purpose. Describe the default and new channels. The new channel is the one that communicates with MS 38 after changing hands. Processing begins with MS 38 receiving the transmission of the first AS, denoted AS (0). MS 38 was simultaneously transmitted in the channel of source cell BS1 32. A call recovery trigger occurs at time tl. Both MS 38 and BS1 32 found the trigger. It should be noted that the trigger can be a common event, such as the continuous PC requirement of BS1 32 by MS 38 to increase the FL transmission power, or -19-This paper size applies the Chinese National Standard (CNS) A4 specification (210 X 297 mm)

Description of the invention (17) is a separate event. In addition, MS 38 and BS1 32 may not detect triggers at the same time. MS 38 often finds triggers before BS1 32. When the identification trigger occurs at time t1, the BS1 32 starts the preset channel transmission from the neighboring BS2 34. This start may be performed by the BSC 26. At time t2 BS2 34 starts transmitting on the preset channel. This transmission is the same as that of BS1 32. When the trigger starts, the MS 38 inhibits the transmitter for a predetermined waiting period. At the time t3, the waiting period ends and the MS 38 transmits the preamble at period Y. At the same time, the AS of MS 38 changes from AS (O) to AS (1). The base stations identified by AS (1) are all base stations referenced by the final PSMM. In an alternative embodiment AS (1) may also be all neighbors of BS1 32. The preamble is suspended at time t4 and the MS 38 starts transmitting the current PSMM. Response PSMM received at time t5, BS1 32 and BS2 34 send HDM at time t6. At time t8 the HDM notifies the AS (2) AS change. Note that the next PSMM is sent at time t7, where PSMMs are sent periodically to identify signals received by the MS 38. At time t8 BS2 34 starts transmitting on the new channel to MS 38. The MS 38 transmits the HCM at time t9 to trigger the suspension of transmission of the MS 38 on the preset channel. In the case illustrated in FIG. 9, the call resume starts at time t2 and is suspended at time t9. The handover is completed at time t9 and BS2 34 is the current source cell base station for MS 38. The receiver channel RX2 illustrates an alternative scenario. Here AS (O) is still active before time t5. After time t5, MS 38 continues to receive from AS (O) for a predetermined period X, and then becomes eight 3 (1).

An alternative embodiment may use an open-circuit power controller. Open circuit, for the transmitter (mobile station or base station) control operation, not directly V and receiving state. For example, a special reverse link open-circuit power control call for a mobile station adjusts the reverse link transmission according to the power level of the signal received by the forward link from the base station. $ Power L force rate control extends the open-circuit operation, so the receiver is functional. Ground participates in power adjustment decisions. For example, for rl closed-loop power control, the base station will compare the signal power level and threshold value of the signal received from a predetermined mobile station. The base station then instructs the mobile station to increase or decrease the reverse-link transmission power based on the comparison result. Conversely, the mobile station monitors the power level of the signal received by the FL and provides the FL quality &lt; feedback to the base station. Closed-circuit operation can be used to compensate for power changes related to the fading of a given link, such as fading in Korat. Immediately after the handover and before power control is established, the MS 38 starts transmitting at the starting power level. The RL transmit power level can be restored just before the MS 3 8 transmitter is disabled. The power level may remain at this starting level before the closed-loop power control is restored. In an alternative embodiment, the power level starts at the final level before the transmitter is disabled and then ramps up at a predetermined rate until the power control resumes. . This increase speed is set by BS1 32 and / or BS2 34 and can be a fixed value or variable. This is increased until the RL closed-loop power control resumes. Another embodiment starts restoration with open circuit control based on the total received power of the frequency band. This procedure is similar to the entry procedure.

Invention ^ ~ 9—y &quot; —A knot base station can correct this process. Open circuit control continues until closed circuit power control resumes. FIG. 10 illustrates the power adjusted according to this embodiment. The horizontal axis indicates time and the vertical axis indicates the transmission power level of 7F. At the first time ti the transmission power is at the starting power level. After the first period, the transmission power is increased by a predetermined increase 2 at time t2. The increase may be a fixed value or a variable that increases or decreases with time. The value added in Guan Shi Ju Ju can be adapted and responded to according to the system's 10 status, where the added value can be increased or decreased from one time to the subsequent period. Finally, a predetermined maximum transmission power level can be reached after a predetermined period. The transmitted power then spikes and waits for closed-loop power control to resume. In another embodiment, the starting power is based on the received signal quality. Signal quality is measured by leading Ec / I0 or leading Ec who want AS. In open-circuit power control, the transmission power relationship is usually Τχ = (-ΙΙχ) + 1ί, where k is the cumulative correction coefficient &apos; Tx is the transmission energy of RL and Rx is the reception energy of FL. For closed-circuit power control methods, the transmission power relationship is often Tx == (_ Rx) + k + y (t), where y⑴ is another cumulative correction variable. The item (k + y⑴) is called cold. An alternative form is the following relationship: Tx + Rx = k + y (t). The determination of the initial transmission power refers to the previous transmission to the new transmission. Then calculate the new transmission power level with Tx (t) = (-Rx (t) + Tx (0) + Rx (0), where τχ (〇) is the transmission energy before the call resumes, and Rx (0) is the call resume The previous received energy. In this way the transmission power is adjusted according to the previous ratio of the transmitted power level to the received power level. Figure 11 illustrates a wireless device MS 38, such as a cellular phone or a personal digital assistant (PDA), operating in the system 10 of Figure 1 ). MS 38 includes an antenna 300 for transmission and reception.

The communication bus 318 is also coupled with the memory 322 and the restoration adjustment unit 316. The memory 322 stores computer-readable instructions for various operations and functions available in the MS 38. The processor 320 executes The instructions stored in the memory 322. Under normal operating conditions, the power control unit generates a PC signal from the multiplexer 3 12 to the power adjustment 310. The power adjustment 310 then converts the pC signal to the amplification level of the amplifier 304. When When the call is restored, the MS 38 can disable the transmitter. When the transmitter is restarted, the handover completion signal is supplied to the restoration adjustment unit 316. The handover completion signal instructs the restoration adjustment unit 3 16 to generate a predetermined PC signal. This pc signal can be used for any The above-mentioned generation of the starting RL transmission power structure or an alternative method can be implemented. The handover completion signal is also used to control the multiplexer 3 12. After the call is restored, the PC signal generated by the 'restore adjustment unit 3 16' is sent to the power adjustment unit 3 10. At the same time, the closed-circuit power control is started. Once the closed-circuit power control is completely restored, the cancel handover completion signal and the multiplexer 3 12 select the power control unit 3 14 to generate The PC signal is supplied to the power adjustment 310. The operation of the restoration adjustment unit 316 can be performed by the microprocessor 320 operated by software instructions or can be implemented by the hardware with effective and reliable operations. -23-This paper standard applies to the Chinese National Standard (CNS) A4 Specifications (210 X 297 mm) 1235614 A7 B7 V. Invention Description (21) In one embodiment, the specific operation of MS 38 or BS1 32 is considered a special event. Special events include a variety of conditions and procedures that can achieve a false trigger. That is, a special event can cause a call recovery trigger to occur but the trigger is not important. A special event is the mobile position locator search. The MS 38 is instructed to search the Global Positioning System (GPS) at an alternative frequency. GPS information provides MS 38 location. Periodically search for the location of mobile stations. MS 38 usually has prior information about this search time. Alternative embodiments can implement any number of special events, where triggers are ignored in special events. Other events may include actions taken by the MS 38 when the trigger is ignored. In this case MS 38 notifies the source cell BS1 32 that there is a special situation. In one embodiment, the special event is a possible frequency search, in which Ms 38 is adjusted to different frequencies to search for neighboring base station signals at that frequency. This enables better conversion of different frequency coverage areas, such as personal communication system (1 &gt; (: 8) frequency and cell frequency. When this mobile station starts a special situation, MS 38 informs the source cell BS1 32 in Ignore the trigger on Ms 38 for a certain period of time or before re-notification. According to an embodiment, in order to avoid this false trigger from occurring in special events, for example, the source cell base station of Bsi notifies MS 38 of the search time, which includes at least the search on time and Search for a long time. Ms 38 prohibits call recovery from triggering a call recovery at a special event. In an alternative embodiment, Ms 38 notifies BS1 32 that a special event has occurred. = 32 In response to this notification, you can agree to the special event, reject the event, or This item is rescheduled. #; Ow this provides MS 38 with enough information to trigger a ban on call reinstatement in a special event. -24-

Description of the invention (provide new and improved methods to maintain communication in the wireless communication system. When there is a problem with the communication link between the mobile station and the corresponding source cell base station 'Pre-arrangement of the mobile station and basic architecture Possible rescue base stations. Source cell base stations contact all recoverable neighbors as possible rescuers. Rescue neighbors have predetermined preset channels and mobile station soft handovers. The preset channels are only temporarily used in the initial handover part. Instructions Each rescue station uses the preset channel for rescue transmission. The rescue transmission is considered as a call recovery operation. The mobile station and the rescue base station establish a soft handover, of which FL uses the preset channel. The rescue base station then starts transmitting on the alternative channel. Once the handover is completed The rescue base station stopped using the default channel transmitted to the mobile station. In one embodiment, the source cell base station provided the mobile station with a recoverable proximity list during transmission and before forming a communication link problem, as mentioned earlier. So, In the case of missing the FL before receiving the handover information, the mobile station has enough information to perform the handover. For example, more than one preset channel is allocated to the neighboring BS2 34. Using multiple preset or rescue channels will increase the call resilience of the system 10. Each neighboring can then recover more than one mobile station such as MS 38. During the call Before recovery, the source cell BS1 32 provides the identification codes corresponding to multiple channels related to MS 38 and BS2 34. _ 38 and BS2 34 each store a decision function such as a messy signal function to match the identification code with a specific channel. The messy signal function is special It is used for pseudo-random procedures. In addition, an electronic serial number is allocated to MS 38.

Description of the invention (2 ~)---- The messy signal function of the data structure can be used only to check in the data structure: secondary identification-keywords in the group word. The chaotic signal function compares its parameters with pre-locked results. Messy signal functions are known and stateless. That is, the value of f is only related to the parameters and the same parameters get the same results. Minimizing the impact is important for the clutter signal function, where impact is two different parameters that clutter the same value. It is also important that the clutter signal value is uniformly distributed, that is, the probability of the clutter signal function to reply to any predetermined type of specific value should be about the same as that of any other value. Other forms of cryptographic functions may be implemented in alternative embodiments to identify multiple preset channels for call recovery. When the call resumes, the transmission power level of the mobile station is not controlled by the base station. When the mobile station starts or restarts the transmitter, it decides which transmission power to choose. In one case, the transmission power of the PSMM and the initial power level of the PSMM are determined before the call resumes. The starting level can be a fixed level or can be dynamically adjusted based on system architecture, environmental considerations, geographic considerations, usage records, or any factors that affect communications. For the system of Figure 1, the MS 38 determines the transmission power level for transmitting the preamble and pSMM information. It can be implemented in various scenarios to adjust the transmission power ', two of which are shown in FIG. In one embodiment, as shown in FIG. 12A, the preamble and PSMM are transmitted in a predetermined interval named kl. The transmission power level is predetermined to be a fixed value PFixed. This fixed value can be the final transmit power level before the call resumes. The fixed transmission power level is the final transmission power level adjusted by the difference between the increase and decrease of the received power after the transmitter is disabled after MS 3 8 is disabled. Instead of calculating the transmission power level as a function of the previous transmission power level, such as adding one to increase the value △. In one embodiment, the transmission power level is first -26-This paper size applies the Chinese National Standard (CNS) A4 specification (210X 297 mm) 1235614 Invention description (a constant level of 24 mobile stations.

It is acknowledged that it can be an HDM message Or it can be approved by PSMM layer 2. If Ms 38 cannot reach HDM or approval within a predetermined period, MS 38 will stop transmitting the foreword and PSMM information and cancel the call recovery. Once MS 38 decides that the forward link has sufficient transmission quality, Transmission power level restores power control. In the _ embodiment, the two correct frames are continuously received by the forward link to achieve the product. According to an embodiment, when the forward link is sufficient to transmit and the reverse power control is restored, the mobile station also resumes the normal traffic transmission of the reverse link when it continues the PSMM transmission with no preamble at ki intervals. Is the link sufficient to meet The transmission quality criterion is usually determined by the system architecture and parameters, but any number of criteria can be used. In addition, the criteria can be dynamically adapted to the system operation. Figure 12B illustrates an alternative embodiment in which the transmission power level is adjusted incrementally during the restart of the transmitter. The first preamble and PSMM are transmitted at the first power level P1. The ratio of the total transmission power of the PSMM and the preamble to the preamble and the subsequent leading channel transmission power is maintained at a predetermined ratio y, expressed in decibels. As shown in the embodiment of FIG. 12A, The foreword and PSMM are repeated in h cycles, but the total transmission power increases with successive occurrences. The increase size can be gradual, where the increase value or step size is predetermined and depends on the system. Increase value or step -27-This paper size is in accordance with Chinese National Standard (CNS) A4 (210 X 297 mm) 1235614 A7 B7 V. Description of the invention (25) The size can be replaced by the base station. Users should note that alternative embodiments can implement variable time intervals. In addition, the number of transmissions of the preface and PSMM information can change with time or each occurrence. The transmission power level is increased to the maximum value Pmax. The transmission power level is no longer available Increase, but maintain the maximum value for subsequent transmissions. In one embodiment, the level P MAX is determined by BS1 32 and sent to the MS 38. An alternative embodiment may fix the PMAX level. When receiving HDM or layer 2 approval from PSMM, move The station resumes normal traffic and reverses the power control of the base station. According to an alternative embodiment, when the forward link reception quality reaches a predetermined level, the transmission of the preamble and PSMM continues until the HDM or Layer 2 approval of the PSMM is received, and the reverse power control of the base station resumes. FIG. 13 illustrates a method 400 for restarting a transmitter at a mobile station in a call recovery according to an embodiment. In step 402, the preamble and the transmission power Pτχ of the PSMM are initialized with the final transmission power PTx0ld function of the mobile station before the restoration process. In one embodiment, PTx is set equal to the total power received by the mobile station before the restoration process and the total power received by the mobile station after the restoration of the call is PRxNEW. The adjusted PtxOLD ° is provided in step 402 of FIG. The initial transmit power level is the final transmit power level adjusted by adding or subtracting the difference between the total received power of the MS 38 and the transmitter's last ban. The preamble and PSMM are transmitted at this power level. The initial transmit power level of the alternative embodiment may refer to a predetermined power level. The mobile station is waiting to receive the approval of the PSMM information from the base station. In the illustrated embodiment, at decision block 404, the mobile station checks whether HDM is received. An alternative embodiment checks the layer 2 approval of the PSMM. There are also embodiments that check for layer 2 approval or HDM. The mobile station transmits the preamble and PSMM information in k! Cycles. The mobile station continues to check the HDM during and between transmissions. When k! -28-This paper size applies the Chinese National Standard (CNS) A4 specification (210 X 297 mm) 1235614 A7 — — ___B7 V. Ming (26) --- ~ — During the receipt of HDM, the mobile station steps 406 returns to normal traffic processing, where the reverse power control continues with the power control command received from the base station. If HDM is not received during ki, the mobile station is ready to transmit the next preamble and psMM. In decision block 408, the mobile station compares the current transmission power Pτχ with the maximum power level ρΜAX. It should be noted that in one embodiment, the process checks after step 406: the received transmission quality. In an example process check to see if there are two consecutive connections: OK. If two consecutive good boxes are not received, processing continues at decision block 408. However, if two consecutive good frames are received, the process transmits the former and PSMM at the control power level and skips to decision block 416. Similarly note that when the mobile station checks whether it has received hdm or other PSMM approval in step 404, the reverse power control restarts after receiving two consecutive good frames. The result of receiving two consecutive good frames is to skip the processing of increasing the preamble and "" 乂 transmission power. ^ Pτχ is smaller than P \ ααχ ', proceed to step 412 and add Pτχ. The increase may be a fixed increase value according to the daily sound or may be a variable step size. Alternative embodiments may transmit multiple times at each transmit power level before each increase. In step 414, the mobile station transmits the preamble and PSMM at the adjusted power level. Decision block 416 is then continued to determine if the transmitter restart cycle has expired. If pTx is equal to or greater than pMAx, proceed to step 410 to transmit with PMAx. Continuing decision block 416 returns to decision block 404 if the period has not expired. If the period expires, the mobile station terminates the call resumption in step 418. In one embodiment, in order to prevent the base station from unnecessarily triggering the call resumption, the mobile user displays a non-use when searching for a possible frequency of the hard handover. In this search, the mobile user can move away from the current frequency during a period sufficient to trigger a call recovery. -29-This paper size applies to China National Standard (CNS) A4 specifications (210 X 297 mm) 1235614 A7 B7 5. Description of the invention ( 27) rate. By providing a display of the base station's actual call recovery status, the call recovery can be avoided. While the transmitter is restarting, the mobile station waits for the forward link to recover, where recovery is usually defined by two consecutive correct boxes received at the mobile station.
