Description
Technical Field
The present invention relates to wireless communication technologies, and in particular, to an information processing method and a terminal.
Background
With the popularization of Voice over LTE (VoLTE) based IMS, VoLTE + G dual-card single-pass terminals are now on the market. The VoLTE + G dual card single-pass terminal can solve the problem that a user inserts a USIM (Universal Subscriber Identity Module) card subscribed to VoLTE, that is, only one card can be used to dial VoLTE calls, while the other card must use traditional Circuit Switched (CS) voice to dial calls. This is a positive push for operators to release Global System for Mobile communications (GSM) frequency bands through full commercial maturity of VoLTE, leading existing CS users to upgrade to VoLTE with adverse effects. It is highly desirable to provide a dual-card dual-LTE-capable single-pass terminal, in which the primary card or the secondary card can selectively support VoLTE or support VoLTE simultaneously.
The technical scheme of the current dual-LTE dual-card single-pass terminal realizes that dual cards respectively reside in an LTE network by using the advantage of a radio frequency architecture that a main card of the current terminal supports carrier aggregation. That is to say, when the main card supports the carrier aggregation between downlink bands, the main card has two relatively independent receiving channels and one uplink transmitting channel; when the dual-LTE dual-card terminal is in the VoLTE coverage area, because the terminal is a single-pass terminal, only two radio frequency receiving channels of the main card for downlink carrier aggregation can be separated into one channel for standby of the secondary card. When any card of the main card and the auxiliary card has VoLTE voice or data service, the uplink transmitting channel is occupied.
The disadvantages of the prior art solutions are as follows:
1. in the prior art, a radio frequency architecture that a main card supports downlink carrier aggregation must be used to support standby of an auxiliary card LTE, otherwise, it cannot be guaranteed that the auxiliary card can receive a VoLTE or Circuit Switched Fallback (CSFB) page; the technical scheme that the main card has downlink carrier aggregation is basically applied to high-end machines, and the low-end machines cannot support the carrier aggregation technology due to the reason of cost and the like, so that the scheme cannot be applied to all types of terminals.
2. In the prior art, because a carrier aggregation radio frequency architecture needs to be borrowed and each operator has a specific carrier aggregation radio frequency combination, even if a radio frequency carrier aggregation high-end computer is pushed out, the mobile phone dual cards cannot be supported to adopt different operator card combinations. For example, if the main card supports china mobile carrier aggregation radio frequency combination, the mobile phone does not support the use of dual VoLTE by inserting the main card into a smart card of china mobile and inserting the auxiliary card into a smart card of china unicom. The main problem is how to guarantee that the secondary card can monitor the paging from VoLTE or CSFB when the primary card performs data service. Because the dual standby is realized between the main card and the auxiliary card of the terminal in a radio frequency punching mode, if the auxiliary card is in an LTE connection state and the auxiliary card is called, the network side directly sends an Invite message to the auxiliary card of the terminal, and the terminal can miss the Invite message, so that the calling of the auxiliary card fails.
