Problems solved by technology

[0007] (2) Cross-system switching is realized, but the switching process controlled by the mobile terminal device is not involved, that is, the software and hardware architecture of the mobile terminal device side is not improved
[0009] For the Android system, at this stage, users can only use the unified authentication communication dialing function of mobile broadband + wireless broadband in the mobile terminal device of the Android system, and choose two different networks of mobile broadband or wireless broadband for access. The switch between mobile broadband and wireless broadband network access will cause the user's business connection to be interrupted, requiring re-selection of the network, re-initiation of service access authentication, and allocation of a new IP address, and automatic seamless switching cannot be achieved

[0063] image 3 Shown is a schematic flow chart of the method for switching from a mobile broadband network to a wireless broadband network in the Android system of the present invention, including the following steps:

[0064] In step 301, the mobile terminal equipment uses the mobile broadband network to access the Internet. When the handover control unit judges that the handover condition is satisfied, it calls the SIP session unit to establish a SIP session to trigger handover to the wireless broadband network.

[0065] The handover condition defines the signal strength threshold for the wireless broadband network. If the mobile terminal device accesses the Internet through the mobile broadband network, it detects that the signal strength of the wireless broadband network is greater than the first strength threshold, it triggers switching from the mobile broadband network to the wireless broadband network; if the mobile terminal device accesses the Internet through the wir...

[0104] Figure 12 It is a schematic flow diagram of a method for switching from a wireless broadband network to a mobile broadband network in an Android system according to the present invention, comprising the following steps:

[0105] In step 1201, the mobile terminal equipment uses the wireless broadband network to access the Internet. When the handover control unit judges that the handover condition is satisfied, it sends a link establishment request to the RIL interface to trigger handover to the mobile broadband network.

[0106] In step 1202, the RIL interface redirects the link establishment request sent by the handover control unit to the newly added PPP protocol unit in the application processor, and the PPP protocol unit calls the interface of the mobile broadband communication unit in an AT command mode to initiate PPP dialing and process PPP packets. Wherein, the process of the PPP protocol unit initiating PPP dialing and processing the PPP message is the same as...

Abstract

The invention discloses a different-network switching method and terminal based on an AP (application processor) in an Android system. When a mobile broadband network is switched to a wireless broadband network and an SIP (session initiation protocol) session is established, a PPP (point-to-point protocol) unit initiates a PPP dial and processes a PPP message, a switching control unit intercepts a PPP data message transmitted by the mobile broadband network, and the data message undergoes a tunnel encapsulation and then is transmitted to the wireless broadband network. When the wireless broadband network is switched to the mobile broadband network, an RIL (radio interface layer) interface redirects a link establishment request to the PPP unit, i.e., a whole switching process uses the PPP unit in the AP, and the switching control unit intercepts PPP data originally transmitted by the wireless broadband network and sends the PPP data to the mobile broadband network. According to the invention, the continuous operation connection is guaranteed without the PPP renegotiation authentication required in different-network switching and without the redistribution of IP addresses of the mobile terminal device.

Description

technical field [0001] The present invention relates to the field of mobile terminal equipment (mobile phone, tablet computer, etc.), in particular to a method and a terminal for realizing seamless switching between a mobile broadband network and a wireless broadband network based on an AP (Application Processor, application processor) in an Android system. Background technique [0002] The integration and synergy of mobile broadband (CDMA, WCDMA, HSPA, LTE, etc.) and wireless broadband (WiFi) has become a hot spot in the industry. [0003] figure 1 Shown is a prior art architecture diagram of WiFi and CDMA network fusion networking. Among them, PDSN, AN / AAA, HLR / AuC, DO RNC, BSC / PCF, and BTS are standard network elements of CDMA network, AP, AC / BAS are standard network elements of WiFi network, and WAG is a wireless LAN access gateway for unified authentication , the above-mentioned network elements are network elements of the live network. [0004] The integration of mo...
