Compared with the single CDMA chip dual card dual standby mobile phone paging listening method described in the prior art, it is possible to realize single CDMA chip single protocol stack dual card dual standby mobile phone in the same operator's network environment to listen for Hu, solved the problem of single CDMA chip dual card dual standby mobile phone standby. The method uses a set of protocol stacks to manage and control two UIM cards, and realizes the application of two UIM cards on a single CDMA chip dual card dual standby mobile phone. 5 201038092 [Embodiment] As shown in Fig. 1, it is an architectural diagram of a preferred embodiment of a single CDMA chip dual card dual standby handset of the present invention. The dual-card dual standby mobile phone includes a physical control layer 1 ' (referred to as "L1 layer"), a link layer 2 (referred to as "L2 layer"), signaling processing, layer 3 (referred to as "L3 layer"), call management layer 4, user interface 5, and two user identification modules (hereinafter referred to as UIM1 card and UIM2 card) 6. Among them, L2 layer and L1 layer and L3 layer are connected to each other, and can exchange information in both directions, call management layer 4 respectively Connected to the L3 layer and the user interface 5. The L1 layer is used to provide an interface between the mobile phone CDMA chip and the application layer software, and controls the wireless communication between the internal chip of the mobile phone and the application layer software. It is used to send data, receive data, data flow control and perform authentication processing. The L3 layer includes a set of CDMA chips for listening to paging frequency, paging channel and paging of UIM1 card and UIM2 card. Paging listening parameters such as time limit, and management of radio resources, mobility, and supplementary services of the dual-card dual standby mobile phone. The call management layer 4 refers to the interface layer of the user interface 5 and the protocol stack, which is used to implement Call management. The UIM1 card and UIM2 card are respectively associated with L The Layer 2, L3 layer, the call management layer 4 and the user interface 5 are connected to implement the paging function of the dual card dual standby mobile phone. The L2 layer includes the data sending module 21, the data receiving module 22 and the security. The data transmission module 21 is configured to send the data processed by the L3 layer to the wireless channel, and control the traffic of the data to be sent. The data receiving module 22 is configured to receive the data transmitted by the wireless channel. And controlling the traffic of the received data. The security supervision module 23 6 201038092 is used for authenticating the UIM1 card and the UIM2 card. The authentication process refers to screening legitimate users and allowing access to the network. In the process of obtaining the service, the process actually refers to the process of “interrogation and response” between a UIM card and the network. „ As shown in FIG. 2, it is a message sequence of the single CDMA chip dual card dual standby mobile phone system standby according to the present invention. Figure. The dual-card dual-standby mobile phone utilizes the communication between the L1 layer, the L2 layer, the L3 layer and the UIM1 card and the UIM2 card to listen to the paging of the UIM1 card and the UIM2 card. Listening to UIM1 cards and UIM2 The key to card paging is to receive pages for each UIM card according to their respective search frequency, paging channel and paging time limit. Assume that the dual-card dual-standby mobile phone first uses the UIM1 card for paging, and the L3 layer sends the wake-up parameters (for example, L1_WAKEUP_R, 1^1—1^8. 0_11, 1〇^_\¥8{^1;?_] ^) to 1; 1]\11 card, so that the 1]1]^1 card is in the awake state, the L3 layer is notified on the paging time limit of the UIM1 card, and the data receiving module 22 of the L2 layer is used from the paging channel. Receive paging & messages on. If the UIM1 card is not called, the U L3 layer determines whether the paging frequency of the UIM1 card and the UIM2 card are the same. When the paging frequency of the UIM1 card and the UIM2 card are different, the L1 layer causes the UIM2 card to be awake by transmitting the above-mentioned wake-up parameter to the UIM2 card, and sends a sleep parameter (for example, L1-SLEEP_M, L1_REACQ_R) to UIM1. The UIM1 card is put to sleep on the card. The L3 layer switches the paging frequency to the paging frequency of the UIM2 card, notifies the L3 layer on the paging time limit of the UIM2 card, and uses the data receiving module 22 of the L2 layer to receive the paging message from the paging channel. If the UIM2 card is not called, the L3 layer determines whether the paging frequency of the UIM1 card and the 7201038092 UIM2 card are the same. When the paging frequency of the UIM1 card and the UIM2 card are different, the L1 layer causes the UIM1 card to be awake by transmitting the wakeup parameter to the UIM1 card, and the UIM2 is enabled by sending the sleep parameter to the UIM2 card. The card is in a sleep state. The L3 layer will page. The frequency point is switched to the paging frequency of the UIM1 card, and the L3 layer is notified on the paging time limit of the UIM1 card, and the data receiving module 22 of the L2 layer receives the paging message from the paging channel. . As shown in FIG. 3, it is a flowchart of a preferred embodiment of the paging ping method for a single CDMA chip dual card dual standby mobile phone according to the present invention. In step S10, the mobile phone is turned on, and the mobile phone system is initialized. In step S11, the L1 layer reads the message of the UIM1 card and initializes the UIM1 card. In step S12, the L1 layer searches for the wireless network according to the normal CDMA protocol procedure using the paging listening parameter of the UIM1 card, and the paging listening parameters include a paging frequency, a paging channel, and a paging time limit. In step S13, the L3 layer reads the overhead message of the mobile phone system, and records the paging frequency, paging channel and paging time limit of the UIM1 card. Step S14, ^ L3 layer controls the UIM1 card to initiate a network registration process to the wireless network, and completes the registration of the UIM1 card network. In step S15, the L3 layer determines whether the UIM2 card is in an awake state. If the UIM2 card is in the awake state, in step S16, the L1 layer reads the message of the UIM2 card and initializes the UIM2 card. In step S17, the L1 layer uses the paging listening parameter of the UIM2 card to search for the wireless network according to the normal CDMA protocol procedure. In step S18, the L3 layer re-reads the overhead message of the mobile phone system, and records the paging frequency, paging channel and paging time limit of the UIM2 card. In step S19, the L3 layer controls the UIM2 card to initiate a network registration to the wireless network, and completes the registration of the UIM2 card network. In the step S15, if the UIM2 card does not exist or is in the dormant state, the flow directly proceeds to step S20. Step S20, and the L3 layer determines whether the paging frequency of the UIM1 card and the UIM2 card are the same. In step S21, if the paging frequency of the UIM1 card and the UIM2 card are the same and the paging channel is the same, the method of performing the same frequency point and the paging channel is used to listen to the paging (see FIG. 4). In step S23, if the paging frequency or the paging channel of the UIM1 card is different from the UIM2 card, the inter-frequency paging method is used to listen to the paging (see FIG. 5). As shown in FIG. 4, step S21 in FIG. 3 uses the same frequency point and the paging channel method to listen to the detailed flowchart of paging. In step S210, the L3 layer determines whether the paging time limit of the UIM1 card and the UIM2 card are the same. The paging time limit specified herein refers to the value of the paging time limit period period in the usual sense. If the paging time limit of UIM1 and UIM2 is the same or the difference is less than or equal to the overhead time of the system switching, the flow proceeds to step S211. If the paging time limit of the UIM1 card ^ and the UIM2 card is different and the difference is greater than the overhead time of the system switching, the flow proceeds to step S219. Step S211, the L3 layer configures the paging listening parameter of the UIM1 card to the L1 layer. In step S212, the L3 layer notifies the L1 layer to enter a sleep state, calculates the time of the next wakeup, receives the page when the wakeup is awakened, and sends a message to the L3 layer. In step S213, the L3 layer matches the paging message sent by the L1 layer with the UIM1 card. In step S214, the L3 layer determines whether the paging message matches the information of the UIM1 card. In step S215, if the paging message does not match the information of the UIM1 card, the L3 layer configures the paging listening parameter of the UIM2 card to the L1 9 201038092 layer. Step S216 'L3 layer notifies the L1 layer to enter a sleep state'. The L1 layer counts the time of the next wake-up, then the layer sleeps, wakes up, receives the paging, and the L1 layer sends a paging message to the L3 layer. Step S217, the L3 layer matches the paging message sent by the L1 layer with the card. Step S218: The L3 layer determines whether the paging message matches the information of the UIM2 card. If the paging message does not match the information of the UIM2 card, the flow moves to step S211 to repeat the above process from the UIM1 card. In step S214 and step S218, if the paging message matches any UIM card (UIM1 card or UIM2 card), the flow proceeds to step S225 to end standby, that is, the matching UIM1 card or UIM2 card initiates a response process to the wireless network. . In step S219, the L3 layer compares the time of searching for the beer between the UIM1 card and the UIM2 card, and configures the paging parameter of the former to the L1 layer. Step S220' L3 layer notifies the L1 layer to enter a sleep state, and the L1 layer calculates the time of the next wake-up, receives the page when it is woken up, and sends a message to the L3 layer. When the sleep command sent by L3 is not received, the L1 layer will always receive the ^page message and send it to the L3 layer. In step S221, the L3 layer matches the paging message sent by the L1 layer to match the UIM1 card or the UIM2 card. In step S222, the L3 layer determines whether the paging message matches the information of the UIM1 card. Step S223: If the paging message does not match the information of the UIM1 card, the L3 layer determines whether the paging message matches the information of the UIM2 card. Step S224' If the paging message does not match the information of the UIM2 card, the L3 layer determines whether the paging time limit of the UIM1 card and the UIM2 card is terminated by the latter paging time limit. If the paging time limit of the UIM1 card and the UIM2 card is limited by the latter paging time, the flow proceeds to step S220. If the paging time limit of the UIM1 card and the UIM2 201038092 card is not ended by the latter, the flow moves to step S221. In the above steps S222 and S223, if the paging message matches any UIM card (UIM1 card or UIM2 card), the flow turns to • Step S225 ends the standby, that is, the matching UIM1 card or UIM2 card is initiated to the wireless network. Response process. As shown in FIG. 5, step S23 in FIG. 3 uses a different frequency point different calling channel method to listen to the detailed flowchart of paging. In step S230, the L3 layer determines whether the paging time limit of the UIM1 card and the UIM2 card is the same. Step S231, 〇 If the time limit of the UIM1 card and the UIM2 card are the same or the difference is less than or equal to the overhead time of the system switching, the L3 layer configures the paging listening parameter of the UIM1 to the L1 layer. In step S232, the L3 layer notifies the L1 layer to enter the sleep state, and the L1 layer calculates the time of the next wake-up, receives the page when it is woken up, and sends a message to the L3 layer. Step S233, the L3 layer matches the paging message sent by the L1 layer with the UIM1 card or the UIM2 card. In step S234, the L3 layer determines whether the information of the paging message and the UIM1 card is ^ no match. In step S235, if the paging message is not matched with the information of the UIM1 card, the layer I] L3 determines whether the paging frequency of the UIM1 card and the UIM2 card are the same. Step S236, if the paging frequency of the UIM1 card and the UIM2 card are different, the L3 layer tunes the paging frequency point to the paging frequency of the UIM2 card. Step S237, the L3 layer configures the paging listening parameter of the UIM2 card to the L1 layer. If the frequency of the UIM1 card and the UIM2 card are the same, the flow directly proceeds to step S237. In step S238, the L3 layer notifies the L1 layer to enter a sleep state, the L1 layer calculates the time of the next wake-up, then sleeps, wakes up, receives the page, and the L1 layer sends a paging message to the L3 layer. 11 201038092 Step S239, the L3 layer determines whether the paging message matches the information of the UIM2 card. In step S240, if the paging message does not match the information of the UIM2 card, the L3 layer determines whether the paging frequency of the UIM1 card and the UIM2 card are the same. Step S241, if the paging frequency of the UIM1 card and the UIM2 card are different, then the L3 layer tunes the paging frequency to the paging frequency of the UIM1 card. If the paging frequency of the UIM1 card and the UIM2 card are the same, the flow moves to step S230 °. In the above steps S234 and S239, if the paging matches any UIM card (UIM1 card or UIM2 card), the flow directly proceeds to the step. S242 ends the standby, that is, the matching UIM1 card or UIM2 card initiates a response process to the wireless network. In the above step S230, if the paging time limit of the UIM1 card and the UIM2 card is different and the difference is greater than the overhead time of the system switching, the flow further performs steps S231 to S242. Although the processes of the two are the same, the implementation principles are different. When the time limit of the UIM1 card and the UIM2 card are different ^ or the difference is greater than the overhead time of the system switching, the inter-frequency paging channel method implements switching between the UIM1 card and the UIM2 card within a paging time period. However, when the paging time limit of the UIM1 card and the UIM2 card are the same and the difference is less than or equal to the overhead time of the system switching, the inter-frequency paging channel method is implemented between the UIM1 card and the UIM2 card in two paging time periods. Switching, that is, one paging cycle is used to receive the paging of the UIM1 card, and the next paging cycle is used to receive the paging of the UIM2 card. Since a page that receives only one UIM card in one paging cycle will miss another page of the UIM card, the network will continuously resend three 12 201038092 times for one page, even if a page may be missed. However, the other two must be able to detect the paging of the UIM1 card and the UIM2 card. The invention solves the problem of standby of a single CDMA chip dual card dual standby mobile phone by providing a single CDMA chip single protocol stack dual card dual standby mobile phone in the same operator's network environment to listen to paging. It uses a set of protocol stacks to manage and control two UIM cards to implement two UIM card applications. Since the two UIM cards belong to the same carrier, the two UIM cards in the same carrier's network environment are in the same wireless environment (such as wireless signal quality, community location, etc.), so two The UIM card can be used in a dual card dual standby mobile phone with a single CDMA chip.
