Mobile terminal and service processing method thereof, and baseband processing chip

Abstract

Disclosed are a mobile terminal and a service processing thereof, and a baseband processing chip. The service processing method of the mobile terminal comprises: in response to that a first subscriber identity module card in an online state needs to process a highly real-time service, identifying whether PS domain data being received or sent in a currently processed PS domain service of a second subscriber identity module card is key data for maintaining the quality of the PS domain service, the highly real-time service being beyond the real-time requirement of the PS domain service, and the first subscriber identity module card and the second subscriber identity module card belonging among multiple subscriber identity module cards inserted in the same mobile terminal; in response to that the PS data being received or sent is non-key data, suspending processing of the PS domain service and processing the highly real-time service. The embodiments of the present invention enable the multi-card multi-standby mobile terminal based on the single-radio frequency single-baseband scheme to process highly real-time services on other subscriber identity module cards while processing the PS domain service on one of the subscriber identity module cards.

Description

technical field [0001] The invention relates to communication technology, in particular to a mobile terminal, a service processing method thereof, and a baseband processing chip. Background technique [0002] At present, a user of a mobile communication system registers with a mobile communication network and uses various communication services provided by the mobile communication network by inserting a user card into a mobile terminal. Existing mobile terminals mostly use a single user card, and a user can only use one user card at the same time on the mobile terminal. However, with the gradual increase of users' needs in work and life, each user needs to use multiple user cards at the same time. In order to meet this demand, a multi-card multi-standby mobile terminal emerges as the times require. The multi-card multi-standby mobile terminal refers to a mobile terminal that can insert more than two user cards at the same time, and multiple user cards can be in the standby ...

Problems solved by technology

However, regardless of whether the two carriers belong to the same operator or different operators, because the Global System for Mobile Communications (Global System for Mobile Communications, hereinafter referred to as: GSM) network design does not consider a radio frequency chip to receive two carriers at the same time, especially In the case of two carriers of different operators, and if the distance between the two carriers is large, it is difficult for the same RF chip to receive two different carriers at the same time, resulting in packet switching (Packet Switch, hereinafter referred to as: PS) on one of the SIM cards. ) domain service conflicts with other services other than the PS domain service on other SIM cards, making it impossible to process high real-time services on other SIM cards in a timely manner during the PS domain service on one SIM card, such as circuit Switching (Circuit Switch, hereinafter referred to as: CS) domain services, thus increasing the failure rate of high real-time services on other SIM cards

[0006] For example, when one SIM card is performing PS domain services, the other SIM card cannot receive CS domain paging messages, so it cannot normally process CS domain communication services and perform location area updates based on CS domain paging messages.

If the location of the mobile terminal changes when one of the SIM cards is performing PS domain services, the failure to update the location area will cause the other SIM card to be out of sync with the mobile communication network, which will cause the other SIM card to be out of sync with the mobile communication network. The phenomenon of card disconnection is serious and increases the failure rate of subsequent services
