| --- | MS0032 | --- | --- | Grp02 | Secure group |
S22: the group attribute of the call service group that inquiry and call service group's number are corresponding is flexible group that the non-member terminal of restriction adds the secure group of group calling or allows non-group membership's terminal to add.
In the present embodiment, the group attribute that call service group's number is Grp01 is flexible group, and termination number is that the call service group that the colony terminal request of MS0001, MS0011, MS0021, MS0031 will participate in group calling allows non-group membership's terminal to add; Group call number is Grp02 group attribute is secure group, and termination number is that call service group that the colony terminal request of MS0002, MS0012, MS0022, MS0032 will participate in group calling limits non-group membership's terminal and adds.
S23: judge whether the colony terminal that termination number is corresponding is group membership's terminal of the call service group that call service group's number is corresponding.Particularly, step S23 comprises: judge that corresponding participation sets of numbers is organized in participation under colony terminal whether consistent with call service group number.
If it is consistent with call service group number to participate in sets of numbers, colony terminal is group membership's terminal of the call service group that call service group's number is corresponding.In the present embodiment, the participation sets of numbers of the colony terminal that termination number is MS0012 is consistent with call service group number, is Grp02, therefore the colony terminal that termination number is MS0012 is group membership's terminal of the Grp02 of call service group.Termination number is that the participation sets of numbers of colony terminal of MS0001 is consistent with call service group number, is Grp01, therefore the colony terminal that termination number is MS0001 is group membership's terminal of the Grp01 of call service group.
If it is inconsistent to participate in sets of numbers and call service group's number, group membership's terminal of the call service group that colony terminal Bu Shi call service group number is corresponding.In the present embodiment, termination number is that participation sets of numbers and the call service group's number of colony terminal of MS0002, MS0022, MS0032 is inconsistent (wherein, termination number is that the participation sets of numbers of the colony terminal of MS0032 is sky), therefore termination number is group membership's terminal of the colony terminal Jun Bushi Grp02 of call service group of MS0002, MS0022, MS0032.In like manner, termination number is group membership's terminal of the colony terminal Bu Shi Grp01 of call service group of MS0011, MS0021 and MS0031.
Understandably, in the present embodiment, the order of step S22 and step S23 can be exchanged.
S3: if the group attribute of call service group is secure group, and group membership's terminal of colony terminal Bu Wei call service group, restriction set group terminal adds the group calling of call service group, to colony terminal feedback restricted participation group calling information.More specifically, in step S3, also comprise: in terminal information table, register information corresponding to termination number is arranged to enrollment status.
In the present embodiment, termination number is MS0002, MS0012, MS0022, the group attribute that the colony terminal request of MS0032 will participate in the Grp02 of call service group of group calling is secure group, and termination number is MS0002, MS0022, group membership's terminal of the colony terminal Jun Buwei Grp02 of call service group of MS0032, therefore by the MS0002 in terminal information table shown in table one, MS0022, MS0032 is updated to enrollment status (as shown in Table 2), it cannot be rested on participation group Grp02, do not record its register information, take limiting terminal number as MS0002, MS0022, the colony terminal of MS0032 participates in the group calling of the call service group that the number Grp02 of call service group is corresponding, make the call-information that it cannot monitored call group Grp02, and restricted participation group calling information is fed back to colony terminal.Understandably, core net can not fed back restricted participation group calling information to colony terminal, and with tacit declaration mode restriction set group terminal, adds the group calling of call service group.
S4: if the group attribute of call service group is flexible group, or the colony terminal group membership's terminal that is call service group, allow colony terminal to add the group calling of call service group, to colony terminal feedback, allow to participate in group calling information.More specifically, step S4 also comprises: in terminal information table, register information corresponding to termination number is arranged to enrollment status.
In the present embodiment, termination number is that the group attribute that the colony terminal request of MS0001, MS0011, MS0021, MS0031 will participate in the Grp01 of call service group of group calling is flexible group.Termination number is that the colony terminal of MS0012 is that group membership's terminal of the Grp02 of call service group, the colony terminal that termination number is MS0001 are group membership's terminal of the Grp01 of call service group.Therefore by the termination number in terminal information table shown in table one, be that MS0001, MS0011, MS0021, MS0031, MS0012 register information are updated to enrollment status (as shown in Table 2), the colony terminal that the permission termination number of take is MS0001, MS0011, MS0021, MS0031 participates in the group calling of the call service group that call service group's number is Grp01, and the colony terminal that permission termination number is MS0012 participates in the group calling of the call service group that call service group's number is Grp02; And feed back to by allowing to participate in group calling information the colony terminal that termination number is MS0001, MS0011, MS0021, MS0031, MS0012.Understandably, core net yet can not send and allow to participate in group calling information to colony terminal, and allows colony terminal to add the group calling of call service group in tacit declaration mode.
In the present embodiment, termination number is that the participation group of the colony terminal of MS0031 is not determined by writing frequently, when system is opened an account, determine that it can participate in the group calling that call service group's number is the call service group of Grp01, can determine that the colony terminal of termination number MS0031 is for participating in group membership's terminal of the participation group that sets of numbers is Grp01, its number of base stations can be the number of base stations TSC01 of the base station that sends group calling request signal.
Understandably, when if core net receives same group calling request signal again, can to colony terminal, send and allow to participate in group calling information or restricted participation group calling information according to the register information of terminal information table (as shown in Table 2), or allow or restriction set group terminal participates in the group calling of call service group in tacit declaration mode.
Table two terminal information table
| Participate in sets of numbers | Termination number | Register information | Number of base stations | Call service group's number | Group attribute |
| Grp01 | MS0001 | Enrollment status | TSC02 | Grp01 | Flexible group |
| Grp01 | MS0002 | Remove enrollment status | TSC01 | Grp02 | Secure group |
| Grp02 | MS0011 | Enrollment status | TSC01 | Grp01 | Flexible group |
| Grp02 | MS0012 | Enrollment status | TSC01 | Grp02 | Secure group |
| Grp03 | MS0021 | Enrollment status | TSC01 | Grp01 | Flexible group |
| Grp03 | MS0022 | Remove enrollment status | TSC01 | Grp02 | Secure group |
| Grp01 | MS0031 | Enrollment status | TSC01 | Grp01 | Flexible group |
| --- | MS0032 | Remove enrollment status | TSC01 | Grp02 | Secure group |
In the present embodiment, by the group attribute difference minute secure group of call service group corresponding to call service group's number and group flexibly, by the setting of secure group, can effectively avoid non-group membership's terminal to be added in the group calling of the call service group that group attribute is secure group, avoiding organizing attribute and be the call-information of the call service group of secure group reveals because of the eavesdropping of non-group membership's terminal, and its process can effectively be saved system resource, the processing speed of raising group system.And, in the situation that group attribute is flexible group, the colony terminal that can directly allow to send group calling request signal adds the group calling of call service group, to increase flexibility and the convenience of group calling, avoid directly determining whether group membership's terminal and determine that can it participate in the group calling of call service group, and restriction set group terminal adds the group calling of other call service groups.
In the present embodiment, the way to manage that introducing group is adhered in the group calling management method of digital packet terminal, as shown in Table 1, the group attribute of determining Grp01 when writing is frequently for allowing non-group membership's terminal to participate in flexible group of group calling, and the group attribute of the Grp02 manufacture-illegal group membership terminal that is limited participates in the secure group of group calling.While writing frequently, can make termination number is MS001, the colony terminal of MS002 belongs to and participates in sets of numbers is the participation group under Grp01, be that termination number is MS001, the colony terminal of MS002 for participate in sets of numbers Grp01 group membership's terminal of participation group, when the colony terminal that termination number is MS001 is initiated the group calling request signal of the call service group that is Grp01 to call service group's number on the TSC02 of base station, core network processing terminal number is the group calling request signal of the colony terminal of MS001, judgement participates in all group membership's terminal registration positional informations of the participation group that sets of numbers is Grp01, for example, if there is the register information of group membership's terminal of the participation group that participates in sets of numbers Grp01 under the base station except master station TSC02 (TSC01), it is its allocation of channel resources, otherwise this calling allocation of channel resources under the TSC01 of base station that core net is not initiated for MS001, to save Radio Resource.
Understandably, in the present embodiment, can adopt OTAP to eat dishes without rice or wine to write mode frequently, fast a plurality of colony terminals be write frequently to a participation group, to tackle, in emergency circumstances need to gather in the situation that a plurality of colony terminals participate in a participation group.As when large-scale earthquake occurs, while needing a large amount of personnel of set to participate in earthquake relief work, making all personnel participate in call service group's number is that the group calling of the call service group of Grp01 is example, local police strength is 500 people (termination number is MS0001～MS0500), 500 local colony terminals all write in the participation group that its participation sets of numbers is Grp01, number of base stations is TSC01, in addition from A, B, C tri-cities are interim increasing person 300 people respectively, termination number is A city (MS0501～MS0800), B city (MS0801～MS1100), mode is frequently eated dishes without rice or wine to write by core net OTAP by C city (MS1101～MS1400), fast literary sketch is frequently to participating in participation group that sets of numbers is Grp01, its number of base stations is respectively TSC02, TSC03 and TSC04, adopt in this way, when having large-scale contingency tasks, can the group calling of Rapid Establishment super large scope, thereby at utmost alleviate personnel and property loss.
