Embodiment Construction

[0032] Hereinafter, the present invention will be described in detail with reference to the drawings and in conjunction with the embodiments. It should be noted that the embodiments in the application and the features in the embodiments can be combined with each other if there is no conflict. In addition, it should be noted that, for the purpose of clarity, representations and descriptions of components and processes that are not related to the present invention and are known to those skilled in the art are omitted from the drawings and the description.

[0033] The invention discloses a method and a terminal for a terminal to automatically switch data links:

[0034] The method includes: after the application processor (AP) receives the notification from the modem (MODEM, also called the wireless side) to establish the first network connection, it retrieves the APN required to establish the first network connection, and when the APN retrieval is empty, it notifies The MODEM is sw...

Abstract

Disclosed are a terminal and method for a terminal automatically switching data link. The method comprises: after receiving a notification from a modem for setting up a first network connection, an application processor retrieves an access point name (APN) required for setting up the first network connection, and notifies the modem to switch to a second network connection when the retrieved APN is null; the modem switches to the second network after receiving a network connection change notification transmitted by the application processor, and notifies the application processor. The method and terminal of the present invention can automatically switch to a second network to set up a data link when the APN required for setting up a first network connection does not exist and data traffic cannot be used.

Description

Technical field [0001] The present invention relates to the field of mobile communication, in particular to a method and terminal for a terminal to automatically switch data links. Background technique [0002] HRPD (High Rate Packet Data), also known as EVDO (Evolution-Data Optimized), is a high-speed wireless data technology based on CDMA (based on 3GPP2 protocol specifications). In recent years, the fourth-generation communication technology has become increasingly mature, and 4G LTE networks have been widely used because of its ultra-high data transmission speed and good performance. And LTE is based on 3GPP protocol specifications, so eHRPD (enhanced High Rate Packet Data) was born as a bridge from CDMA to LTE. eHRPD is an evolution and enhancement of the original HRPD network. It uses the core network of LTE and the access network of EVDO, which can smoothly switch with LTE. Improved the way of network integration so that resources can be used rationally. eHRDP and HRPD...
