Service processing method, a baseband processor chip and a terminal

Abstract

A service processing method, a baseband processor chip and a terminal are disclosed in embodiments of this invention, wherein the service processing method comprises: in response to a need for processing a CS domain service by a terminal, identifying whether PS domain data that is being received / transmitted in a PS domain service currently processed by the terminal is critical data for maintaining the QoS level of the PS domain service; in response to that the PS domain data being received / transmitted is not critical data, suspending the processing of the PS domain service and processing the CS domain service. The embodiment of this invention enables a terminal of Class B to process a CS domain service during the process of receiving / transmitting PS domain data.

AI Technical Summary

Benefits of technology

[0022]Based on the service processing method, the baseband processor chip and the terminal provided in the above embodiments of this invention, when a terminal requires to process a CS domain service, whether PS domain data being received / transmitted in a currently processed PS domain service is critical data for maintaining the QoS Level of the PS domain service is identified, if the PS domain data being received / transmitted is not critical data, the processing of the PS domain service is suspended and the CS domain service is processed. The problem of unable to process a CS domain service during the processing of a PS domain service on a terminal of Class B in the prior art can be solved. As compared to the prior art, the terminal of Class B is enabled to process a CS domain service during its reception / transmission of PS domain data, so that user experiment about the CS domain service and the QoS level of the CS domain service can be improved; in addition, because the PS domain data being received / transmitted is not critical data, suspending the processing of the current PS domain service will not cause the degradation in QoS level of the PS domain service, such as, a break of the PS domain service or a significant decrease in data transmission speed of PS domain data.

Problems solved by technology

A terminal of class B can be attached to a GPRS network and a GSM network simultaneously, but it does not support the concurrent operation of a PS domain service and a GSM voice service, and can only operate one service at a certain time.

However, in existing networks, a terminal of Class B is unable to receive a GSM service message, such as a voice call or a SMS message while receiving a PS domain data transmission.

The operation of a terminal of Class A needs a large amount of Central Processing Unit (CPU) bandwidth, which results in high cost and expensive price.

Terminals of Class C are not suitable for PS domain service requests, and thus most of the GPRS terminals available on the current market are terminals of Class B.

Because a terminal of Class B does not support the concurrent processing of a PS domain service and a Circuit Switched (CS) domain service, when the terminal of Class B is engaged in a continuous reception / transmission of PS domain data during the process of a PS domain service, it is unable to process a CS domain service.

For example, when a terminal of Class B is continuously receiving PS domain data, if a calling user makes a call to a called user, the call request can not be admitted to the called terminal, and the called terminal does not present any prompt except to the called user while the calling terminal will receive a prompt that “the number you dialed is engaged”, which may impacts the success admission rate of a GMS voice service consequently.

If the missed call reminder service is not turned on, the called user cannot be informed about the missed call at all, leading to serious impacts on user experience about the service.
