Problems solved by technology

This method has the following disadvantages: In a dual-card dual-VoLTE terminal, only the main card provides LTE data services through the data service PDN connection, and the secondary card only needs to provide voice services
If the main card is idle at this time, considering that the LTE paging cycle is generally 1.28s, the above process is likely to conflict with the paging subframe of the main card; if the main card is performing LTE data services at this time, the above process will affect Main card LTE data service experience

Abstract

The embodiment of the invention discloses a public data network (PDN) connection control method and a terminal. The terminal comprises a first user identification card used for bearing data business and a second user identification card used for bearing non-data business. The method comprises the steps of when the terminal detects a preset mode, detecting a resident network of the second user identification card; and when the second user identification card is registered to an IP multimedia sub-system (IMS), deleting a data business PDN connection of the second user identification card.

Description

technical field [0001] The present invention relates to wireless communication technology, in particular to a public data network (PDN, Public DataNetwork) connection control method and terminal. Background technique [0002] According to the service characteristics of IMS-based voice services (VoLTE, Voice over LTE) and full packet switching (PS, PacketSwitch), VoLTE+G (where G represents the Global System for Mobile Communications (GSM, Global System for Mobile Communication) network) has been proposed. The card terminal solution enables long-term evolution (LTE, LongTerm Evolution) dual-card terminals to also have VoLTE features. With the commercialization of VoLTE by all domestic operators, it is necessary to continue to promote the upgrading of dual-card terminal products to meet the needs of dual-card dual-card VoLTE voice calls, that is, dual-card dual-VoLTE terminals. [0003] In a dual-card dual-VoLTE terminal, although both cards can access the LTE network, only o...
