As a typical operation of a wireless communication system, BS 270 receives reverse link signals from various terminals 100. Terminal 100 typically participates in calls, messaging, and other types of communications. Each reverse link signal received by a particular BS 270 is processed within a particular BS 270. The obtained data is forwarded to the relevant BSC 275. The BSC provides call resource allocation and coordinated mobility management functions including a soft handoff procedure between the BSs 270. The BSC 275 also routes the received data to the MSC 280, which provides additional routing services for interfacing with the PSTN 290. Similarly, PSTN 290 interfaces with MSC 280, MSC 280 interfaces with BSC 275, and BSC 275 controls BS 270 accordingly to transmit forward link signals to terminal 100.

Specifically, in an embodiment of the present invention, the first processing unit 130 and the second processing unit 140 are connected through a data interface (for example, a UART data interface). The information of the subscriber identity card is passed to the second processing unit 140.

In order to realize the interaction of the card information between the first processing unit 130 and the second processing unit 140, the communication protocol between the first processing unit 130 and the second processing unit 140 is divided into a physical layer, a transport layer, and an application layer. The physical layer is configured to transmit and receive data. The transport layer can extend multiple interfaces and are configured to correspond to different services opened by the application layer. The application layer is configured to enable the service to perform the corresponding information acquisition function.

Specifically, referring to FIG. 4, first, the first processing unit 130 and the second processing unit 140 respectively perform configuration of one or more ports. In an embodiment of the invention, the port is a virtual logical port, and the configuration port includes a port number for which to be set, and the like. According to the function division, the port includes two types. The first one is used for the port corresponding to the service registered by the application layer, and the information acquired by the application layer service is transmitted to the transport layer; the second is used for the physical interface with the physical layer. Corresponding ports transmit information to the corresponding physical interface to enable the transmission (or reception) of information.

Specifically, the first processing unit 130 registers a service to perform a corresponding function. In an embodiment of the invention, the service may be a preset service. For example, if the information of the acquisition card is used as the preset service, when the second processing unit 140 sends the synchronization frame to establish a connection with the first processor, the first processor can register the preset service. Thereby performing the function of the preset service. In an embodiment of the invention, the preset service is information for acquiring a user identification card.

In the embodiment of the present invention, the functions of different services are different, for example, a service for acquiring card information can be registered. Other types of services, such as services for obtaining status information, control information, and the like, may also be registered in embodiments of the present invention. Each service corresponds to a port, that is, the information acquired by the service will be transmitted through the port corresponding to the service. The port here refers to the first port described above.

Therefore, in the embodiment of the present invention, since a plurality of ports (the first type of ports described above) are expandable, respectively corresponding to different services, and different transmission layers can be called according to actual communication transmission requirements to transmit information. To the physical layer interface (for example, USB interface, shared memory interface, etc.) Support for extending multiple transport layer protocols. For example, for a first service, transport layer 1 is called for information transmission, and for a second service, transport layer 2 can be called for information transmission. The transport layer protocols used by different transport layers are different.

The second processing unit 140 transmits a sync frame (synchronization frame) to the first processing unit 130; the first processing unit 130 is further configured to receive a sync frame and reply an acknowledgment frame (ACK) for the first processing unit 130 and the second processing. A connection is established between units 140. In an embodiment of the present invention, when the preset condition is satisfied, the second processing unit 140 initiates a process of connection establishment, that is, transmits a sync frame. Preset conditions can be initialized for power on, restart, etc.

It should be understood that, in the embodiment of the present invention, the first processing unit 130 and the second processing unit 140 establish a connection by sync and ACK, and the first processing unit 130 registers the service in no order. The first processing unit 130 registration service may be before or after the connection is established.

The second processing unit 140 performs service discovery and registers a client corresponding to the service. In one embodiment, the client registered by the second processing unit 140 corresponds to the service registered by the first processing unit 130. And the first processing unit 130 registers the same service, and the client registered by the second processing unit 140 also corresponds to a corresponding port to transmit information to the transport layer through the port, and to the corresponding port through the port of the transport layer. Physical interface.

After the second processing unit 140 registers the client, the first processing unit 130 and the second processing unit 140 may perform information interaction. Specifically, when performing information interaction, a data packet format as shown in FIG. 5 may be adopted. It includes the flag bit (header part), the length (the length of the entire packet), the control flag (the flag is the client or the server), the port number (local port), the service ID, the customer ID, the data ID, the control bit, the message ID, data length, and data.

In an embodiment of the invention, the port number is the port number of the second port, which is used to mark which physical interface the data packet is transmitted to. For example, when the physical interface includes a USB interface and a shared memory interface, the data packet can be correctly transmitted to the corresponding physical interface through the port number, thereby implementing interaction with the second processing unit 140. Thus, when the packet is transmitted to the physical layer, the port number The field can be deleted, that is, the port number field is not included in the packet transmitted to the peer.

In the embodiment of the present invention, the port numbers of different physical interfaces (hardware interfaces) are different. Therefore, by specifying the port number in the data packet, the data packet can be correctly forwarded, so that the information acquired by the application layer registration service can be realized. Send through an accurate physical interface. Thus, the dual-core communication device of the embodiment of the present invention can support extending multiple physical interfaces (that is, extending multiple physical layer protocols).

The service ID is the ID number of the registered service. The client ID is the ID number of the client corresponding to the service. The control bit is used to identify the data packet as a request packet, a reply packet, and the like. The data (data) adopts the type-len-value format, where type is used to indicate the type of the entire data block, len is used to indicate the size of the value area, and value is the data area.

In an embodiment of the invention, a service may need to send multiple data packets, whereby the message ID indicates the sequence number of the transmitted data packet. The data ID is used to distinguish the message type of the packet. A plurality of different types of data may be included in each data packet, whereby one message ID may correspond to multiple types. For example, information such as signal strength and network format can be transmitted as one data packet, and types of different data blocks are indicated by type in the data field, thereby implementing one data packet to transmit multiple information belonging to the same message type. .

It should be understood that the packet format shown in FIG. 5 is merely exemplary, and other similar formats may also be employed.

In an embodiment of the present invention, specifically, the first processing unit 130 configures a first logical port corresponding to the preset service, and configures a second logical port corresponding to the physical interface of the first processor. The information obtained by the preset service is transmitted to the second logical port through the first logical port to be transmitted to the second processing unit 140 through the physical interface of the first processor. The second processing unit 140 configures a third logical port corresponding to the client, and configures a fourth logical port corresponding to the physical interface of the second processing unit 140. The information received by the physical interface of the second processing unit 140 is transmitted to the third logical port through the fourth logical port for transmission to the client.

In an embodiment of the present invention, when the second processing unit 140 is powered off, or an abnormal restart occurs, the second processing unit 140 turns off the client and the port. When it returns to normal, the connection may be re-established with the first processing unit 130 by sending a synchronization frame (sync frame) to re-execute the registration service, register the client, and the like, and perform information interaction.

Similarly, if the first processing unit 130 is shut down or an abnormal restart occurs, the first processing unit 130 will close the corresponding service and port. When the first processing unit 130 returns to normal, the connection may be re-established with the second processing unit 140 by sending a synchronization frame (sync frame) to re-execute the registration service, register the client, and the like, and perform information interaction.

In the embodiment of the present invention, the C/S communication architecture is adopted between the first processing unit and the second processing unit 140 to implement sharing of card information. Therefore, the first processing unit 130 can share the acquired information to the second processing unit 140, so that the second processing unit 140 can obtain the information on the instant. And because different ports are registered for different services, corresponding transmissions can be extended, and multiple physical layer protocols can be extended.

In an embodiment of the invention, both the second processing unit and the first processing unit can perform data services and voice services. Specifically, the second processing unit acquires information of the first user identification card and the second user identification card from the first processing unit by the foregoing method.

The internet.

The second processing unit is configured to perform a web search based on the information of the first subscriber identity card obtained from the first processing unit such that the first subscriber identity card resides in the first 4G network by the second processing unit.

In the embodiment of the present invention, the voice service of the first subscriber identity card and the second subscriber identity card may be performed through a 4G network, or may be a CS voice service through a 2G/3G network. Therefore, in the search period of the search network, the first subscriber identity card can also be registered to the 2G/3G network, and the second subscriber identity card can also be registered to the 2G/3G network. In some embodiments, the first subscriber identity card may also be registered in the 4G network, and when voice is played, fall back to the 2G/3G network. The second subscriber identity card is registered on the 4G network, and when the voice is played, it falls back to the 2G/3G network.
