Embodiment
Should be appreciated that specific embodiment described herein only in order to explanation the present invention, and be not used in qualification the present invention.
With reference to Fig. 2, propose the present invention is based on method one embodiment of multicast mode down load application, comprising:
The application that step S10, multicast source server multicast portable terminal need be downloaded;
In the present embodiment, realization multicast mode down load application is finished by following functional units share: the multicast source server, use shop server, wireless multicast controller and portable terminal.The function of each functional unit is as follows:
The multicast source server: the application that management is downloaded for portable terminal is created multicast group and multicast application as uploading, issue, upgrade and deletion etc. in the suitable time.
Use shop server: connect with the application shop client of installing in the portable terminal, provide the list information of using all application in the shop to using the shop client, and download finish after to the application authentication of chargeing.
Wireless multicast controller: provide and transmit mobile multicasting service.Transmit the input point of service as content in the multicast service, it is responsible for setting up, controlling the transmission bearer of multicast service, also is responsible for the scheduling and the transmission of multicast service transmission simultaneously.The wireless multicast controller also provides all necessary informations (multicast service identifier, IP multicast address, transmission time etc.) of service announcements such as terminal access to multicast service to portable terminal, it also is responsible for administering the safety problem under the multicast pattern simultaneously.
Portable terminal: the shop client is used in download, installation and operation, and the access application shop server is downloaded according to the list of application selection application that the application shop server is returned.
At first, the multicast source server is used to the multicast address cyclic multicast according to the application build multicast group.
Step S11, portable terminal are downloaded described application by using the multicast group that shop server adds described multicast source server from the multicast source server.
When portable terminal needs down load application, start the application shop client in the portable terminal, land the application shop server, use shop server and return list of application, as: application software, classification such as media entertainment, application software comprises: focus recommendation, mobile office, mobile phone safety, network communication, palm life etc.
Portable terminal is by using shop client browse application shop server, select interested application, click " download ", send download request to using shop server, by using the multicast group that shop server adds the multicast source server, the data of the application of beginning receiving group group.
After the multicast source server sends the data of application, send the conversation end notice to portable terminal, the expression data transfer phase finishes.
After portable terminal successfully receives the data of application, send the request of leaving multicast group.
After the wireless multicast controller is received request, this portable terminal is deleted from multicast group, portable terminal leaves multicast group.
Use shop server according to the application program of downloading, report charge information, so far portable terminal down load application program finishes.
In the present embodiment, by adopting the multicast download mode,, alleviate the load of using shop server, save Internet resources with speed down load application efficiently.It should be noted that above-mentioned multicast source server and use shop server can concentrate in the station server and realize, also can be distributed in the different servers.
With reference to Fig. 3, in one embodiment, step S11 can comprise:
Step S111, portable terminal send download request to using shop server, so that use the multicast address of shop server feedback multicast source server;
Portable terminal is when the needs down load application, send download request to using shop server, use shop server and receive the download request of using the shop client, resolve the message body of download request, to using the multicast address that the shop client sends down load application, as 224.10.10.10.
Step S112, add the multicast group of described multicast source server according to described multicast address;
The application shop client of portable terminal is received the message of using the shop server response, message body resolved, and according to given multicast address such as 224.10.10.10, the portable terminal adding multicast group that initiates a session request.Wireless multicast controller handle mobile terminal adds the request of multicast group, this portable terminal is added a member that becomes in the multicast group.
Data in step S113, the receiving group group.
After portable terminal successfully adds multicast group, the data in the beginning receiving group group.
In the present embodiment, portable terminal obtains multicast address by using shop server, and adds the multicast group of multicast source server, realizes the reception of multicast packet.
In the above-described embodiments, step S112 can further comprise:
When the multicast source server is listened to the described application of multicast, add the multicast group of described multicast source server according to the multicast address of using the shop server transmission.
When portable terminal when using shop server and send download request, use the relevant information of the portable terminal that the shop server record request downloads, as the portable terminal model, operating system, IMEI number and IMSI number etc.
Use shop server and judge whether multicast this application of multicast source server, if do not have, then continuation supervision; In the present embodiment, also other audiomonitor is monitored the multicast source server, and snoop results is reported to using shop server.
If multicast source server multicast should use, then use shop server and send PUSH message to portable terminal, the multicast address such as the 224.10.10.11 of down load application program is provided.
After portable terminal was received PUSH message, according to given multicast address initiation session, request added multicast group.
Wireless multicast controller handle mobile terminal adds the request of multicast group, this portable terminal is added a member that becomes in the multicast group.
After portable terminal successfully adds multicast group, the data in the beginning receiving group group.
In the present embodiment, the multicast source server is monitored, when listening to the multicast source server, then notified portable terminal to add multicast group and receive data, realized that the delay of multicast packet receives in multicast application.
With reference to Fig. 4, portable terminal 10 1 embodiment of the present invention are proposed, comprising:
Sending module 11 is used for sending download request to using shop server, so that use the multicast address of shop server feedback multicast source server;
Add module 12, be used for adding the multicast group of described multicast source server according to described multicast address;
Receiver module 13 is used for receiving group group data.
In the present embodiment, portable terminal 10 is downloaded, is installed and shop client, access application shop server are used in operation.According to using the list of application that shop server is returned, sending module 11 sends download request to using shop server, after the application shop server is received the download request of sending module 11, resolve the message body of download request, to the multicast address that adds module 12 transmission down load application, as 224.10.10.10.Add module 12 and receive the message of using the shop server response, message body is resolved,, add the module 12 adding multicast group that initiates a session request according to given multicast address such as 224.10.10.10.The wireless multicast controller is handled and is added the request that module 12 adds multicast group, and this portable terminal 10 is added a member that becomes in the multicast group.After portable terminal 10 successfully adds multicast group, the data in the receiver module 13 beginning receiving group groups.
