As shown in FIG. 3, a plurality of wireless routers are deployed, and a relay function of the wireless router is configured according to different situations, and parameters of the wireless router are set at the same time. So that WIFI can roam.
- FIG. 4 is a software flow diagram of application software provided by an embodiment of the present invention. As shown in FIG. 4, the method includes the following steps:
- Step S400 the application is started
- Step S401 determining whether the mobile phone uses a static IP address
- step S402 If yes, go to step S402, if no, go to step S403.
- Step S402 prompting the user to use the DHCP service to allocate an IP address
- Step S403 determining whether the mobile phone opens the WIFI and connects to the AP (Access Point, access point); if yes, proceeds to step S405, and if not, proceeds to step S404.
- AP Access Point, access point
- Step S404 prompting the user to open the WIFI and connect to the AP;
- Step S405 Release the acquired IP and send a DHCP RELEASE release message; the purpose is to re-initiate a REQUEST request message, so that other users in the network can listen to the user entering the network through the broadcast.
- the DHCP RELEASE message is sent once because the WIFI is connected and assigned IP when the application is not open, but the host name carried in the DHCP REQUEST packet at the time is the default "Android+ random number", so other online users will not It is judged that someone is online, here to send RELEASE - under, to regain the IP, the host name will use "ZTE + user-defined group + user-defined host name,, other online users can also judge that someone is online.
- Step S406 determining whether the user actively requests to leave the program
- step S420 If yes, go to step S420, if no, go to step S407.
- Step S407 determining whether a broadcast DHCP message is received
- step S410 If the packet is received, further analysis is performed according to the packet type, and the process proceeds to step S410. If not, the process proceeds to step S408.
- Step S408 determining whether voice data of the network is received
- step S409 If the voice data is received, the data needs to be stored and played back to step S412. If not, the process proceeds to step S409.
- Step S409 determining whether voice information needs to be sent
- step S406 If the user needs to send a voice message, the recorder function is turned on to save the user voice, and the object is sent according to the object selected by the user, and the process proceeds to step S413, otherwise, the process proceeds to step S406.
- Step S410 Determine whether the received DHCP packet is a REQUEST request packet.
- step S415 it is proved that the user is requesting the IP or renewing the IP address, and then proceeds to step S415 to further determine whether the IP acquisition is successful, and if not, the process proceeds to step S411.
- Step S411 determining whether the received DHCP packet is a RELEASE message
- step S414 If it is proved that the user is actively offline, the process proceeds to step S414 to update the user status, and if not, the process proceeds to step S406.
- Step S412 locally save and play the received voice data
- Step S413 starting the recording function, recording and encoding the user voice, and transmitting according to the sending object selected by the user;
- Step S414 updating the user status to the offline status
- step S415 it continues to monitor whether the DHCP server receives the ACK message. If it is sent, it proves that the IP address requested in the previous REQUEST message is successful, and proceeds to step S416. If the ACK message is not received or other messages are received, the certificate is proved. If the IP address is not correctly obtained, the process proceeds to step S406.
- Step S416, comparing the IP address and the host name in the previously received REQUEST packet with all online users in the existing mobile phone;
- step S406 If the IP address and the host name are the same, if it is proved that the user is not a new user, the process proceeds to step S406, otherwise, the process proceeds to step S417.
- Step S417 judging that the user is based on the host name in the previously received REQUEST packet. Whether to enable the walkie-talkie function;
- "user-defined group” and “user-defined host name”, this can be saved into the database according to the user's input in the interface, and can be read and filled from the database when using. At the same time, this field can be expanded as needed in addition to "ZTE".
- Step S419 actively sending a REQUEST message to notify the newly added user that I am online;
- the newly added user can implement the status update function for the online users.
- Step S420 ending the application.
- the RELEASE message is sent unsolicited to notify other online users that the machine is offline.
- the host name carried in the REQUEST packet has already used the system default "Android+ random number". The instant receipt of such a message by the network user will not affect the judgment of the user status.
- IP and host names in the DHCP protocol correspond to the fields: Requested IP Address and Host Name Address.
- the walkie-talkie function is built into an application and placed in the phone.
- the Android system you can make a separate APK to implement the walkie-talkie function.
- FIG. 5 is a schematic diagram of a software module of an application software according to an embodiment of the present invention.
- the method includes: a user dynamic information collection module 501: determining a user's online and offline status according to a DHCP protocol; and a transmission module 502: the module Responsible for receiving voice data through the network, and sending data to the network, and sending the received data to the storage module; storage module 503: the module is negative Responsible for storing the voice received from the transmission module and the voice information to be sent to the network and related user ID, IP address and other information; also responsible for storing the local user ID and group information;
