Embodiment
The basic ideas of technical solution problem of the present invention are: the user that will satisfy certain condition earlier is configured to the designated user of Resources allocation (being designated hereinafter simply as designated user) separately, by identifier (IMSI to this user, ESN etc.) identification, outside the shared resource of original group system, independent Resources allocation, this cover resource can independently distribute and discharge, and relative shared resource has the mobility and flexibility that exceeds the general user when inserting with switching.Thereby guarantee mobility, flexibility and the speech quality of this user in trunking communication.Perhaps avoid the wasting of resources uneven when user distribution or that the interior certain user's mobility of group causes very by force.
Be example with CDMA (Code Division Multiple Access, code division multiple access inserts) standard group communication system below, the present invention will be described in detail in conjunction with the accompanying drawings.
In the present embodiment, can in advance following three kinds of cluster users be set at the designated user of Resources allocation separately:
First kind, the responsible consumer in the group as group leader, leader etc., is set to designated user preferentially to satisfy its call performance requirement by it.
Second kind, there is other cluster user often to reside in the independent zone, these users can be set at designated user.
The third, the user that some mobility is very strong is set at designated user.
Above-mentioned second kind and the third situation, specifically can specify, for example, often reside in a certain zone when a group has only a few users according to user's job specification and behavioural analysis, as the field office, can these users be set to designated user so.When learning that the certain user is often or just at airplane or train, can these users be set to designated user, or the like.Need to prove, more than three kinds of specific modes can combination in any select for use, and the present invention's these three kinds of modes of being not limited to list can correspondingly be specified according to other actual needs of network and user.
The set-up mode of concrete designated user can be finished by the user who is given this administration authority in trunking dispatch server, dispatcher, operator or the cluster, and the present invention does not do agreement.After the setting, can in the cluster user attribute of network side preservation, indicate its whether designated user, generally be arranged in the cluster home location register, inquire about for trunking dispatch server.Simultaneously, whether oneself be specify information such as user, affiliated group number and operating time, these information all be kept in flash terminal in to user terminal if can understand by information updating.
The flow process that the trunked communication system group calling of present embodiment is set up may further comprise the steps:
Step 310, the caller colony terminal is initiated the group calling request, and call message is sent to trunking dispatch server by base station system and cluster client end;
Step 320, trunking dispatch server are judged in this group whether designated user of user, for domestic consumer, and execution in step 330, for designated user, execution in step 360;
Step 330, trunking dispatch server sends the user's connection request message (being also referred to as conventional group calling connection request message) that comprises this group's group descriptor through the base station system of cluster client end to the domestic consumer place;
Step 340, after base station system is received described user's connection request message, the air traffic channels resource of set up sharing and and cluster client end between shared link, transmission comprises the shared channel assignment message of group descriptor, finishes message to trunking dispatch server signalling of bouquet call setup then;
After step 350, user terminal are received the shared channel assignment message, judge oneself whether designated user, if the terminal of designated user does not respond this paging, if domestic consumer's terminal, connecting system finishes automatically;
Step 360, to each designated user in the group, trunking dispatch server sends the user's connection request message (be also referred to as and strengthen group calling connection request message) that comprises this designated user descriptor respectively through cluster client end to its place base station system, user descriptors can be IMSI (InternationalMobile Subscriber Station Identity, international mobile subscriber identity) or ESN (ElectronicSerial Number, Electronic Serial Number) etc.
After step 370, base station system were received described user's connection request message, the user descriptors structure beep-page message according to wherein sent to designated user;
Step 380, user terminal are returned page response to base station system after receiving the beep-page message that sends to oneself separately;
Step 390, after base station system is received page response, transmit this page response by cluster client end and give trunking dispatch server, base station system and trunking dispatch server are that designated user sets up independently that a cover resource transmits voice and signaling, comprise the link between Traffic Channel and base station and dispatch server.
In communication process, dispatch server with designated user and affiliated group binding thereof together, voice and signaling in the group are transmitted to designated user, also the voice of this designated user and signaling are forwarded to simultaneously the domestic consumer in the group, thereby guarantee the link and the same voice and the signaling information of original domestic consumer shared link transmission of designated user.
Above flow process can be with reference to Fig. 3, but it should be noted, the order of the relevant signaling of call setup of domestic consumer and designated user only is the needs that show among the figure, and both walk abreast in practice.
In sum, by being the independent Resources allocation of designated user, for the user of fast moving designated after, just can avoid shared channel resources to move and constantly set up with it, thus conserve network resources.And for appointed responsible consumer in the cluster, it inserts success rate, handover success rate, speech quality and mobility and all is greatly improved.And has only the situation of indivedual designated users for a certain zone, trunking dispatch server just can not send public user's connection request to this regional base station system, this base station system just can not set up a cover shared resource yet, thereby has reached the purpose of conserve network resources.
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 are when making various corresponding changes and distortion according to the present invention; in the group system that is applied to different systems, these change and are out of shape the protection range that all should belong to the appended claim of the present invention accordingly.
For example, according to basic thought of the present invention, in another embodiment, can also carry out user's appointment in real time, its step is as follows:
The first step, the caller colony terminal is initiated the group calling request, and call message is sent to trunking dispatch server;
In second step, trunking dispatch server is judged current state or its distribution situation of described group user, and qualified user as designated user, was carried out for the 4th step, to other domestic consumer, carries out for the 3rd step;
The 3rd step, trunking dispatch server is notified the base station system paging domestic consumer at this domestic consumer of group place, base station system is set up shared resource for this group, press group descriptor and initiate paging, domestic consumer's terminal is received behind this group beep-page message connecting system automatically, share the shared resource that is distributed, finish;
The 4th step, trunking dispatch server is passed through the corresponding base station system to each designated user in this group, initiate paging with this user descriptors respectively, behind the page response of receiving the designated user terminal, base station system and trunking dispatch server are set up a cover resource separately for it and are transmitted voice and signaling, finish.
Judge in second step that the user distribution situation can be meant that whether number of users in each base station system of judging the group user place is less than a threshold value, in this way, with the user under this base station system as designated user, otherwise with the user under this base station system as domestic consumer.Judge that user's current state can be whether to judge it in high-speed mobile, as judge that whether its translational speed surpasses a threshold value, if, with this user as designated user, otherwise as domestic consumer.But, the present invention is not limited to above two kinds of situations to user's real-time appointment.
Concrete steps and first embodiment in the 3rd step and the 4th step can be identical, no longer repeat here.As can be seen, this embodiment can reach the saving Internet resources equally by real-time designated user, technique effects such as the mobility of raising designated user conversation, flexibility, success rate.
