Fig. 4 has provided the flow chart of group calling authentication, and concrete steps are as follows:
Step 405 after PDS obtains the authorization message of all group members, sends the message that the group member message pick-up finishes to PHR.
Fig. 5 has provided the flow chart that secret is exhaled (another user's of customer call calling in the group system) authentication, and concrete steps are as follows:
Does step 503 judge that authentication passes through? authentication is by then forwarding step 504 to, otherwise forwards step 505 to.
Fig. 6 has provided the flow chart of Call Forwarding authentication.Calledly in group system be provided with Call Forwarding, and other conditions also satisfy the Call Forwarding condition, PDS can change authentication before the request of commentaries on classics authentication request message before PHR sends, and concrete steps are as follows:
Does step 603 judge that authentication passes through? authentication is by then forwarding step 604 to, otherwise forwards step 605 to.
Fig. 7 has provided the flow chart of group member authentication.In group system, when a group member that just adds after group calling is set up was initiated group calling, PDS can send the authentication of group member authentication request message request group member to PHR, and concrete steps are as follows:
Does step 703 judge that authentication passes through? authentication is by then forwarding step 704 to, otherwise forwards step 705 to.
Fig. 8 has provided the flow chart of subscription authentication.In group system, as the user being added by force in the ongoing group calling, PDS can send the subscription authentication of subscription authentication request message requests to PHR, and concrete steps are as follows:
Does step 803 judge that authentication passes through? authentication is by then forwarding step 804 to, otherwise forwards step 805 to.
Fig. 9 has provided the flow chart of position registering and authentifying, in group system, terminal is exhaled rising, regularly registration, all can carry out location registers under the multiple situations such as switching to right discriminating system, PDS can send position registering and authentifying request message requests position registering and authentifying to PHR during location registers, and concrete steps are as follows:
Does step 903 judge that authentication passes through? authentication is by then forwarding step 904 to, otherwise forwards step 905 to.
Step 904, PHR accepts message message to PDS loopback authentication, and user's information such as IMSI, ESN, MDN and positional information are arranged in the message, and the position is upgraded authorizing procedure and is finished.
Figure 10 has provided the flow chart of management and group authentication.The group leader of group plans additions and deletions and changes group member in group system, and PDS can send management and group authentication request message request management and group authentication to PHR, and concrete steps are as follows:
Does step 1003 judge that authentication passes through? authentication is by then forwarding step 1004 to, otherwise forwards step 1005 to.
Step 1005, PHR contains failure code to PDS loopback authentication refusal message message in the message, show failure cause, and the management and group authorizing procedure finishes.
In sum, the present invention proposes a kind of interface and its implementation that solves the required authentication of group service, constitute a ring important in the GoTa group system.And interface and its implementation of the required authentication of above-mentioned group service are not only applicable to the GoTa system, are fit to too for other digital cluster systems; And the bag of IP wherein not only can adopt udp protocol alternately, also can adopt other modes such as Transmission Control Protocol.
Certainly; the present invention also can have other various embodiments; under the situation that does not deviate from spirit of the present invention and essence thereof; those of ordinary skill in the art work as can make various corresponding changes and distortion according to the present invention, but these corresponding changes and distortion all should belong to the protection range of the appended claim of the present invention.
