Description of the invention: [Technical field to which the invention pertains] The present invention relates to a mobile communication system, and more particularly to a method for enabling a mobile station in an idle state mobile station to perform more efficiently and to assist in handoff. [Prior Art] Fig. 1 illustrates an example of an overall call processing program that starts from a power source of a mobile station of a mobile communication system. When the power is applied to the mobile station, the necessary system information is read from the memory and set in a RAM (or other storage device), and the system is executed by using a navigation channel and a synchronization channel. Synchronize and enter a mobile station start state for receiving the required system information. Included in the message passing through the synchronization channel (eg, a synchronization channel message), system information, associated with a call channel or a P-BCCH (primary broadcast control channel) to allow an idle station to decode the call channel or Frequency information of the P-BCCH, and data rate or coding rate information. If the P-BCCH is used, it additionally includes transmission diversity related information. The idle state of the mobile station means that when the mobile station in the initial state receives all system information and completes the general operation and has received the management from a base station through the call channel or the P-BCCH by using the information transmitted through a synchronous channel message. The status after the message. Some examples of these management messages are a System Parameter Message (SPM) containing system related information, and an Extended System Parameter Message (ESPM) containing information about neighboring bees.

The system access status refers to allowing the mobile station to access a state of the system, and the traffic status refers to when the mobile station is performing communication, i.e., a call is being executed. When a mobile station in the system access state completes a particular operation, it returns to the idle state or traffic state. When in the idle state, if a message transmitted through the call channel or the P-BCCH is not received, the initial procedure is re-executed. For one of the traffic states, if a call ends in execution, the initial procedure is re-executed to re-establish synchronization. The mobile station not only measures the pilot signal strength of a servo base station, but also obtains information about neighboring cells such as PILOT-PN and the like through neighbor messages such as GNLM, ENLM, UNLM, etc., and continuously monitors the guidance of the neighboring cells. Signal strength. Due to this monitoring, if the pilot signal strength of a neighboring cell has exceeded a certain threshold value compared to the pilot signal strength of the servo base station, the mobile station performs a free hand replacement, which means that it has a stronger pilot signal. One of the strength base stations receives a call channel or P-BCCH. Thereafter, the base station that the mobile station is facing when performing the idle replacement hand is referred to as a target base station, and the current base station is referred to as a source base station. In the case where one of the call channels has been received facing a target base station and a P-BCCH has to be received, the problem encountered by the prior art is that the mobile station does not receive decoding of the P-BCCH from the source base station. Any information needed. In detail, as described in Figures 2a and 2b, during the idle state change, the idle state does not directly change to the idle state, but the 6
1292675 行動台朝向該目標基地台,並於進入一系統判定子狀態之 後接收該導引通道及同步通道且自其接收關於該P-BCCH 之資訊,此後才進入該閒置狀態。此造成產生延遲之問題。 此外,在已自該來源基地台接收一呼叫通道且一呼叫 通道於朝向該目標基地台時將被接收的情況中,若於朝向 該目標基地台時由於換手而使該資料速率改變(例如自 4 8 00 bps變為9600 bps ),由於該相關技術行動台應進入該 系統判定子狀態且隨後進入該閒置狀態,因而可能發生延 遲之問題。類似的問題發生於該相關技術行動台已自該來 源基地台接收一 P-BCCH時需要在執行換手至該目標基地 台後接收一呼叫通道。 類似地,在一 P-BCCH已自該來源基地台接收且將自 該目標基地台接收的情況中,若該資料速率或編碼速率或 Walsh編碼於該目標基地台改變,該相關技術行動台應進 入該系統判定子狀態且隨後進入該閒置狀態,因而造成延 遲問題。 若此延遲發生於閒置狀態換手期間,若該相關技術行 動台於閒置狀態中已自該來源基地台接收一廣播服務,則 這些延遲將嚴重影響該廣播服務品質(Q〇s )。換句話說, 由於該相關技術行動台在閒置狀態中透過一轉送補充頻道 (F-SCH )接收一廣播服務,故在執行閒置換手時通過該 系統判定子狀態所造成的該閒置狀態進入延遲所消耗的時 間中無法接收該廣播服務。 7The 1292675 mobile station faces the target base station, and after receiving a system determination substate, receives the pilot channel and the synchronization channel and receives information about the P-BCCH therefrom, and then enters the idle state. This creates a problem of delay. Moreover, in the case where a call channel has been received from the source base station and a call path is to be received towards the target base station, the data rate is changed due to the hand change when facing the target base station (eg Since 4 8 00 bps becomes 9600 bps), since the related technology mobile station should enter the system decision substate and then enter the idle state, a delay problem may occur. A similar problem occurs when the related technology mobile station has received a P-BCCH from the source base station and needs to receive a call channel after performing a handover to the target base station. Similarly, in the case where a P-BCCH has been received from the source base station and will be received from the target base station, if the data rate or coding rate or Walsh code is changed at the target base station, the related technical mobile station should Entering the system determines the substate and then enters the idle state, thus causing a delay problem. If the delay occurs during the idle state handover, if the related technology platform has received a broadcast service from the source base station in the idle state, these delays will seriously affect the broadcast service quality (Q〇s). In other words, since the related technology mobile station receives a broadcast service through a transfer supplement channel (F-SCH) in an idle state, the idle state entry delay caused by the substate is determined by the system when the idle replacement hand is executed. The broadcast service cannot be received during the elapsed time. 7

The present invention provides a method performed by a base station of a mobile communication system to support the idle state of a mobile station. The present invention provides a method of performing a handoff of an idle state mobile station of a mobile communication system that continuously receives a broadcast or multicast service before or after performing an idle state handoff. More specifically, the present invention determines whether the configuration information of the target base station exists in the configuration information previously received and stored from the neighboring base station, and uses the configuration information stored in the target base station when determining that the configuration information exists. The idle replacement hand is executed, or a system judgment substate is returned when it is determined that the configuration information does not exist. Additional advantages, objects, and features of the invention will be set forth in the description which follows. The objects and advantages of the invention will be apparent from the appended claims. 8 1292675 [Embodiment] The present invention has been described as being implemented in a 3 G P P 2 type mobile communication system.

Figure 4 illustrates a program flow of an exemplary embodiment of the present invention. A mobile station in the idle state receives, from the source base station, a management message (S 4 1 ) containing channel information of at least one neighboring base station's P-BCCH through a call channel. The source base station may receive the channel information from a base station controller (B S C ) or some other network entity having similar functions. Some examples of such management messages are General Neighborhood List Message (GNLM), an Extended Neighbor List Message (ENLM), a Universal Neighbor List Message (UNLM), BCMC Service Parameter Message (BSPM), and the like. Here you can see that other types of messages with the same or similar functions can also be used. The BSPM message is a message broadcast to a mobile station that needs to receive a broadcast service, and includes a control message for receiving broadcast service data. It should be noted that if the BSPM is not received, the mobile station can enter the system decision substate before entering the idle state to obtain the necessary broadcast/multicast service parameters. The channel information refers to information used to decode the P-BCCH, and may include information about the P-BCCH usage frequency, coding rate, data rate, and transmission diversity of the P-BCCH.

When performing a handoff, the mobile station uses the channel information retained when receiving from the source base station to receive the P-BCCH transmitted by the target base station with a minimum delay (S43). Therefore, when the mobile station in the idle station is receiving a different service through an F-SCH (Transfer Supplemental Channel), even if the idle replacement hand for a target base station is performed, since it can directly enter the idle state, no The service provided by the source base station can continue to be received from the target base station without interrupting the service connection by the delay caused by a system determination state before entering the idle state. When the mobile station performs an idle state change hand, the operation procedure of the target base station will be described in more detail below. When the mobile station performs the start of the sequence number associated with the management message to be received from the target base station through the P-BCCH, first initiate management associated with an access channel or an enhanced access channel The sequence number associated with the message, from which the source base station receives the PILOT_PNS of the memory to set the value of the BCMC - NGBHR - PN remaining in the store. After receiving a management message from the P-BCCH of the target base station, if the management information retained in the storage is regarded as the latest, the received information is used to execute the hashed new F-CCCH, and since The F-CCCH receives a call and the like. After receiving a management message, if the management information retained in the store is deemed to be non-latest, the mobile station performs initialization of the sequence number of the related message. The tube can be determined by comparing the sequential number of the corresponding message with a stored sequential number.

After the above procedure, the mobile station compares to determine whether the NGBHR_FSCH_FREQ (ie, the corresponding frequency information for receiving one of the FSCH channels of a broadcast monthly service) received by the BSPM of the source base station is related to the target base station. The CDMACHS matches. If they do not match, the CDMACHS is set to NGHBR - FSCH - FREQ and the broadcast from the FSCH is monitored when performing adjustments to a new CDMA channel. So far, it has been explained that the mobile station has received a call channel from the source base station and has received a P-BCCH towards the target base station. In another embodiment, the mobile station receives a P-BCCH from the target base station during the process of receiving a P-BCCH from the source base station, and receives a P-BCCH if the data rate and the coding rate are received. And/or Walsh coding changes, the features of the present invention can be applied. The foregoing case is explained in more detail: when a related technology mobile station performs a handover and has approached a target base station, a delay occurs because the idle state is entered by first entering a system determination state. According to the present invention, the mobile station receives the P-BCCH channel information (frequency, data rate, coding rate, Walsh code, etc.) of the target base station from the source base station in advance through the P-BCCH management message, thereby changing hands. The channel information is used after completion to receive the P-BCCH of the target base station to allow for minimal or no delayed management message reception. In another embodiment of the present invention, if a call channel has been received from the source base station and a call channel is received again toward the target base station, the data rate is changed even when facing the target base station ( Example 18

In this case, the mobile station receives the call channel information of the neighboring base station from the source base in advance through the management message (eg GNLM, ENLM UMLM). , BSPM, etc.), thus using the channel to receive the P-BCCH of the target base station after the handover is completed, allowing the reception of the message without delay. In a further embodiment of the present invention, if a P-BCCH is received from the source base station but a call channel is received after the target base station, the preset data rate of the call channel is transmitted by the target base station (eg, 9600 bps) may be applied to the target base station due to the change of hands, and the features of the present invention can still be applied. In this case, the source base transmits the call channel information (especially, a current data rate) of the target base station to the mobile station through management messages to avoid or minimize unnecessary delays in the handover sequence. In order to implement the various features described above, various types of hardware and/or software components (modules) can be used with the present invention. For example, various hardware groups can include the various circuits and components required to perform the steps of the foregoing methods. Different software modules (by processors and/or other hardware) may contain the various codes and protocols required to perform the steps of the method of the present invention.

The determining step includes: returning to a system determining substate if the configuration information does not exist. The determining step includes: if the configuration information exists, using the storage configuration information of the target base station to perform a free replacement hand. The configuration information is received through management messages. The management message contains a broadcast/multicast service parameter message (B SPM) and a neighbor list message. The neighbor list message includes at least one of a general neighbor list message (GNLM), an extended neighbor list message (ENLM), and a universal neighbor list message (UNLM). The management message includes a field indicating the information of the physical channel used by the mobile station to transmit one of the management messages in the idle state. Information about this physical channel indicates whether transmission diversity is supported. If transmission diversity is supported, appropriate values including parameters for frequency allocation, data rate, marshalling rate, W a 1 s h encoding, transmission diversity mode, and power level can be used. If the mobile station has monitored a PCH before performing the idle handoff and selects a neighboring base station for supporting the P-BCCH idle hand, and the mobile station has received the P-BCCH parameter of the neighboring base station from the BSPM , the mobile station performs a normal handoff procedure. The source base station transmits the management message through a first control channel for managing the message, and the target base station transmits the management message through a second control channel for managing the message. The first and second control channels are broadcast control channels. The first control channel is a PCH and the second control channel is a P-BCCH. 20
