Similarly, the mobile terminal records the status into the online status variable. When the mobile terminal is connected to the Internet server, the connection is maintained.
  • the protocol allows the two parties to stay connected at all times, and the connection between the two parties is lost, and the other party can be connected to the Internet (Internet server or mobile).
  • the terminal perceives that if the connection is lost, for example because of a communication failure or if one party loses power, the other party will respond appropriately. For example, if the Internet server finds that the connection is disconnected, then the mobile terminal number should be recorded in its own database. If the mobile terminal finds that the connection is disconnected, the mobile terminal should first modify its online state variable to be offline, and then try to reconnect. The Internet server does not modify the online state variable to online until the connection is successful.
  • the second determining unit 43 is configured to determine, when determining that the Internet is connected, whether the calling party and the called party have logged into the Internet server, specifically, the online status recorded in the remote server returned by the network protocol stack module 6 Determining whether both the calling party and the called party have logged into the Internet server. If the result returned by the network protocol stack module 6 is that both the calling party and the called party are online, it is determined that both the calling party and the called party have logged into the Internet server; If the result returned by the network protocol stack module 6 is that both the calling party and the called party are not online, it is determined that both the calling party and the called party are not logged into the Internet server.
  • the called party uses its mobile terminal number as an account number and logs in to the Internet server through the network protocol stack module 6. If the Internet server is logged in, the online status is recorded, otherwise the record is offline, and after being recorded as offline, Log back in to the Internet server.
  • the method or specification for judging whether the called party logs into the Internet server can be freely designed, for example, sending the called party's telephone number to the Internet server through the network protocol stack module 6, and the Internet server starts the local database query after receiving the telephone number, and checks whether the number is It has been recorded as online. If it is online, it returns the signal of the called party "called party online” through the network protocol stack module 6, otherwise, it returns the signal of the calling party "the called party is not online” through the network protocol stack module 6.
  • the third determining unit 44 is configured to determine whether the Internet meets the communication standard when it is determined that the Internet server is all logged in.
  • the selecting unit 45 is configured to select an Internet call called party when the determination is yes, and otherwise select a mobile communication network to call the called party. For example, after the second determining unit 43 determines that both the calling party and the called party have logged in to the Internet server, the selecting unit 45 selects the Internet and calls the called party through the network protocol stack module 6; the second determining unit 43 determines that the call is made. After both the party and the called party have logged into the Internet server, the selection unit 45 selects the mobile communication network and calls the called party through the communication protocol stack.
  • FIG. 4 another schematic diagram of a mobile terminal according to an embodiment of the present invention includes:
  • the determining module 81 is configured to determine, when the call is received, whether the call is from the Internet;
  • the mobile terminal will always check whether it is connected to the Internet through the network protocol stack. If it is connected to the Internet, it will log in to the Internet server to identify its online status. This status will be recorded by the database of the Internet server and also recorded in the local online state variable. . If the caller is online, the caller initiates a call through the Internet, then the call signal is transmitted to the antenna through the Internet, and then transmitted to the network protocol stack, which is resolved into a call signal; if it is not online, the communication protocol stack will receive The call signal is transmitted to the communication protocol stack via the primary antenna and is parsed into a call signal. The mobile terminal determines whether the call is from the Internet by determining whether the call signal is parsed by the network protocol stack or parsed by the communication protocol stack.
  • the selecting module 82 is configured to select the Internet for voice communication when the determination is yes, and otherwise select the mobile communication network for voice communication;
  • the user When it is determined that the call is from the Internet, the user is prompted to have a new call on the screen of the mobile terminal, and the voice based on the Internet protocol is started (Voice) Over Internet Protocol

Abstract

L'invention concerne un procédé d'appel et un terminal mobile dans une communication vocale. Un appelant détermine si l'appelant est ou non connecté à Internet lors de l'appel d'un appelé; si oui, il est déterminé si l'appelant et l'appelé sont ou non tous les deux connectés au serveur Internet; si oui, il est déterminé si la qualité de réseau de l'appel par l'intermédiaire d'Internet entre l'appelant et l'appelé satisfait ou non une norme de communication; si oui, l'appelant choisit d'appeler l'appelé par l'intermédiaire d'Internet, autrement choisit d'appeler l'appelé par l'intermédiaire d'un réseau de communication mobile.
