Abstract
When a mobile terminal launches a call within a group, the call through base station is sent to PDSN, and passing through PDSN is forwarded to a cluster server. Based on group calling target group, the cluster server launches a group calling service to all terminals within the group. Copying grouped data brought by calling party is carried out, and the said data through PDSN are distributed to users within the group. In the invention, selection distributing grouped data is adopted to support very large amount of users in a group, and performance is raised. Index of 20-30 users processed in a channel is raised to capability of processing 100 thousands users.
Description
Technical field:
The present invention relates to mobile communication system, relate to the mobile communication system and the method that realize group service specifically.
Background technology:
Cluster communication system is the specific-dispatching communication system, comprises special-purpose commander, dispatching communication, is a kind of communication mode that occurs very early.It is got ready to go into action in hundreds from the form of intercommunication machine one to one, joining common-frequency simplex network construction form, alien frequencies list (two) worker network construction form to single channel and further with the system of selective call, develops into the multichannel automatic dialing system.And over past ten years, the specific schedule system becomes the dispatching patcher that the multichannel user shares again to higher development, and this system is called trunked communication system.A group system will possess two functions at least, and one is group call; Another is that the user presses the response that does not need to obtain other users behind " adding " key and can converse.
Trunked communication system can be divided into simulation trunked communication system and digital clustering communication system according to the technology standard that its internal system adopts.Many trunked communication system suppliers have adopted digital signalling in order to increase the reliability that communicates to connect in trunked communication system, make the speed that connects increase, and systemic-function is also corresponding to be increased.But such communication system can not be at last truly digital clustering communication system.Real digital clustering communication system requires all to carry out digital processing on each link, except digital signalling, the multi-access mode that wherein the most important thing is to be adopted, voice coding technology, modulation-demodulation technique etc. in addition, also comprise simultaneous techniques, error-detection error-correction technology and diversity technique etc.
The digital cluster system of two kinds of TDMA standards of extensive use at present comprises iDEN digital clustering communication system and land trunked radio TETRA (Terresttial Trunked Radio) communication system, iDEN is developed by Motorola Inc., working frequency range 800MHz adopts vector sum excited linear prediction speech coding (VSELP) and 16QAM modulation technique.The TETRA communication system, the digital cluster communication standard operation frequency range that adopts ETSI (ETSI) to recommend is 400MHz or 800MHz, is an aerial signaling interface open system.Its adopt advanced ACELP speech coding and/the 4-DQPSK modulation.
More than two kinds of cluster common networks realize it all being that the second generation digital communication technology that adopts is realized, use be the multi-access mode of TDMA; In the third generation communication technology ripe day by day today, the limitation of TDMA standard also is very tangible: as can not also just not protecting the investment interests of operator smoothly to 3G evolution; The capacity of TDMA standard and throughput all are subjected to the restriction of technology itself, under the situation of sacrificing speech quality, have increased a part of capacity, but still can't satisfy growing communication requirement.
Realize the trunking communication also having standard based on CDMA to realize except the above-mentioned multi-access mode of TDMA that utilizes.As Chinese patent 01132112.1 " method of a kind of mobile communication system and realization group service thereof " a kind of circuit domain trunking communicating technology of realizing based on CDMA is proposed.This patent increases video conferencing equipment at exchanger side, increases secret algorithm simultaneously voice are carried out encryption, is fit to the needs of small-sized trunking communication; But the shortcoming of this patent is the communication requirement that only can be fit to 20-30 node, and in the present practical application to the requirement of trunking communication, such as the flood-fighting commander, what need is to surpass thousands of group to communicate.
The CDMA2000 system has the wide-band spread spectrum air interface, can satisfy the demand of third generation wireless communication system, and traditional voice service not only is provided, and Packet data service at a high speed can be provided.This system has adopted reverse pilot technology, aerial coding method, diversity receiving technology and fast power control technology efficiently widely, in the modulation gain that increases channel, reduced interference again to other users, make the availability of frequency spectrum of CDMA2000 obtain increasing, guaranteed when supporting a plurality of high-speed data users, not reduce original voice user's number, in addition since CDMA exclusive soft handover function, can guarantee the transmission that data service is more stable.If the technology of the system of CDMA2000 can be combined with group system, not only can bring into play the technical advantage of CDMA2000 technology, can also realize user's group service requirement, as group busy, group calling etc.But existing C DMA system is at public network user, can not support the functional requirement of group system.
Summary of the invention
The technical problem to be solved in the present invention is to realize the basic function of group service in existing mobile communications system, make group system satisfy the requirement of 3G system, to adapt to the demand of Development of Communication, a kind of mobile communication system and method that realizes group service proposed thus.
In order to solve above-mentioned technical problem, the system that the present invention proposes comprises the CDMA2000 system at least, supports the travelling carriage and the group data service node (PDSN) of VoIP business; It is characterized in that further comprising: cluster server and dispatching desk; Described cluster server is connected with PDSN by Fast Ethernet, realizes the processing of dispatch call function, the distribution of control dispatch call services; Described dispatching desk is as in the Operation and Maintenance
(3) the cluster server informing base station distributes special-purpose Traffic Channel for user in the group, and all users monitor this channel in the group;
(4) terminal makes a call by the VoIP mode in the group;
(5) base station sends to PDSN after receiving this calling, and PDSN arrives cluster server with this call forward;
(6) the cluster server informing base station is set up reverse traffic channel for this user, and this user stops to listen to forward channel simultaneously;
(7) base station and this user carry out the mutual of data message, and this user data is sent to PDSN;
(8) PDSN sends this user profile to all users in the group on the Traffic Channel of setting up in advance.
The present invention has adopted grouped data to select distribution, can support very large group in the user, have greatly improved on the performance, by circuit domain only can processed group in 20 ~ 30 users' index, rise to the disposal ability that can handle every group 10 general-purpose family.Simultaneously, the present invention combines the function of group system (being private network system) and the function of phone user system (being the public network system), therefore provide more profit growth point for operator, give the user with more selection, change group system in the past owing to the apparatus expensive that monopolization causes, can effectively utilize resource.
