Description
Technical field
The present invention relates to trunking communicating technology, particularly relate to a kind of method that realizes press-and-talk business.
Background technology
In trunking communication, (Push-to-Talk PTT) refers to direct-connected " point-to-point " and " putting multiple spot " voice communication service in real time to press-and-talk.The professional half-duplex operation mode of using of PTT promptly only allow people's speech at one time, and other people can only receive this teller's voice messaging.Use the PTT business, the calling party is as long as need not dialing and wait for that the other side's off-hook just can make a call to a people or lineup by a button, particular talk group is set up in the phone demand working rapidly, therefore be convenient to very much between team, working group and other colony collaborative work with exchange.
PTT has the demand higher than plain old telephone based on the characteristics of " press-and-talk " to access delay.Simultaneously, because the characteristics of " half-duplex " that PTT had communication generally need to adopt dedicated network or transform and realize, develop into special-purpose cluster network on the basis of original telephone network.
Fig. 1 is a kind of cluster network schematic diagram of realizing the PTT business in the prior art.Referring to Fig. 1, in the cluster network of realizing the PTT business, the travelling carriage (MS) in group links to each other with cluster server (PTT Server) by one or more wireless access networks (RAN).RAN can be integrated entity, also can be the entity that comprises base station controller (BSC) and Packet Control Function entity a plurality of equipment such as (PCF).So in order to distinguish, in cluster network shown in Figure 1, RAN1 is integrated entity, RAN2 then comprises BSC and two network entities of PCF.Here, be example with cluster network structure shown in Figure 1, illustrate prior art is how to set up each MS to the link of PTT Server and realize the PTT business.
Referring to Fig. 1, MS1 belongs to same group to MS5, is designated as group 1.MS1 and MS2 are by RAN1 access set group network, and MS3, MS4 and MS5 are by RAN2 access set group network.
Fig. 2 sets up the flow chart of each MS to PTT Server link in the prior art.Referring to Fig. 1 and Fig. 2, when the call setup of group 1, insert successively to MS5 such as MS1, set up each MS in the group 1 so in the prior art and may further comprise the steps to the detailed process of PTT Server link:
Step 201:MS1 inserts RAN1, sets up the dedicated link of link 10 as MS1 between MS1 and RAN1, then, sets up the dedicated link of link 11 as MS1 between RAN1 and PTT Server.
Step 202:MS2 inserts RAN1, sets up the dedicated link of link 20 as MS2 between MS2 and RAN1, then, sets up the dedicated link of link 21 as MS2 between RAN1 and PTT Server.
Step 203:MS3 inserts RAN2, between MS3 and RAN2, set up the dedicated link of link 30 as MS3, between the BSC of RAN2 inside and PCF, set up the dedicated link of link 30 ', between RAN2 and PTT Server, set up the dedicated link of link 31 then as MS3 as MS3.
Step 204:MS4 inserts RAN2, between MS4 and RAN2, set up the dedicated link of link 40 as MS4, between the BSC of RAN2 inside and PCF, set up the dedicated link of link 40 ', between RAN2 and PTT Server, set up the dedicated link of link 41 then as MS4 as MS4.
Step 205:MS5 inserts RAN2, between MS5 and RAN2, set up the dedicated link of link 50 as MS5, between the BSC of RAN2 inside and PCF, set up the dedicated link of link 50 ', between RAN2 and PTT Server, set up the dedicated link of link 51 then as MS5 as MS5.
So far, set up that each MS is to the link of PTT Server in the group 1 that is over, relevant link and group information then can be preserved in RAN1, RAN2 and PTT Server inside.Such as,
Preserve in RAN1 inside: group's group number is a group 1, and the MS of access is MS1 and MS2, and link 10 and link 11 are the dedicated link of MS1, and link 20 and link 21 are the dedicated link of MS2.Preserve in RAN2 inside: group's group number is a group 1, the MS that inserts is MS3, MS4 and MS5, link 30, link 30 ' and link 31 are the dedicated link of MS3, and link 40, link 40 ' and link 41 are the dedicated link of MS4, and link 50, link 50 ' and link 51 are the dedicated link of MS5.Preserve in PTT Server inside: group group number be group 1, the MS of access be MS1 to MS5, link 11, link 21, link 31, link 41 and link 51 are respectively the dedicated link of MS1 to MS5.
Fig. 3 is the flow chart of transmission MS voice messaging when realizing Prepaid ﹠ Postpaid Telephony Service in the prior art.Referring to Fig. 1 and Fig. 3, obtaining speaking right with the MS5 in the group 1 is example, in the prior art, utilizes the detailed process of the dedicated link transmission MS5 voice messaging of each MS that is set up may further comprise the steps:
Step 301:MS5 is link 50 sends self to RAN2 a voice messaging by its dedicated link.
BSC among the step 302:RAN2 receives voice messaging by link 50, knows that this voice messaging sent by MS5, and then the dedicated link by MS5 is that link 50 ' sends to PCF with this voice messaging.
Here, the relevant link information that BSC preserves according to inside is that link 50 is the dedicated link of MS5, and knows that voice messaging sent by MS5.
Step 303:PCF receives voice messaging by link 50 ', knows that this voice messaging sent by MS5, and then the dedicated link by MS5 is that link 51 sends to PTT Server with this voice messaging.
Step 304:PTT Server receives voice messaging by link 51, knows that this voice messaging sent by MS5, and PTT Server duplicates 4 parts with the voice messaging of MS5 then, sends by link 11, link 21, link 31 and link 41 respectively.
Here, after PTT Server receives voice messaging by link 51, relevant link and group information according to the inside preservation, be that link 51 is the dedicated link of MS5, MS5 belongs to group 1, comprises also in the group 1 that MS1 is to MS4, and know that voice messaging is to be sent by the MS5 in the group 1, therefore, PTT Server is that other MS duplicates 4 parts of voice messagings in the group 1, sends by respective link.
After step 305:RAN1 receives voice messaging by link 11, know that this voice messaging should send to MS1, so this voice messaging is sent to MS1 by link 10, after RAN1 receives voice messaging by link 21, know that this voice messaging should send to MS2, so this voice messaging is sent to MS2 by link 20.
In RAN2 inside, after PCF receives voice messaging by link 31, know that this voice messaging should send to MS3, so by link 30 ' this voice messaging is sent to BSC, BSC sends to MS3 by link 30 with this voice messaging again; After PCF receives voice messaging by link 41, know that this voice messaging should send to MS4, so by link 40 ' this voice messaging is sent to BSC, BSC is sent to MS4 by link 40 with this voice messaging again.
So far, each MS receives voice messaging, has realized the PTT business.
If the MS in a plurality of groups is by same RAN access set group network, and carry out the PTT business simultaneously, in the prior art, the relevant information that RAN and PTT Server preserve according to inside is distinguished the link and the voice messaging of each group.Fig. 4 is two groups schematic diagram of access set group networks simultaneously in the prior art.Here, be that example explanation prior art is how to be embodied as different groups the PTT business is provided simultaneously with network configuration shown in Figure 4.
Referring to Fig. 4, such as when the PTT of group 1 business is carried out, the call setup of group 2, terminal MS 6 in the group 2 and MS7 are by RAN1 access set group network, then identical with the above-mentioned link Principle of Process of setting up each MS in the group 1, when prior art inserts at MS6, between MS6 and RAN1, set up the dedicated link of link 60, between RAN1 and PTT Server, set up the dedicated link of link 61 as MS6 as MS6.When MS7 inserts, between MS7 and RAN1, set up the dedicated link of link 70 as MS7, between RAN1 and PTT Server, set up the dedicated link of link 71 as MS7.Correspondingly, the inner and inner relevant information of preserving group 2 of PTT Server of RAN1.
Therefore, when voice messaging arrived RAN1 and PTT Server, RAN1 and PTT Server distinguished the voice messaging of group 1 and group 2 according to link that receives voice messaging and inner relevant information of preserving, and transmit by corresponding link.
This shows that in cluster network, the link that uses prior art to set up realizes that there is following shortcoming in the PTT business:
1, prior art be between RAN and PTT Server, set up with group in the identical link of quantity of MS, therefore can take a large amount of network bandwidths.And, when if RAN inside comprises a plurality of network entity, prior art also need set up between per two network entities that directly link to each other of RAN inside with this RAN under the identical link of MS quantity, when the network entity of RAN inside is a lot, the inner link of setting up of RAN will roll up, therefore, greatly consume the network bandwidth, wasted Internet resources.
2, since the PTT business be used for more between team, working group and other colonies collaborative work with exchange, require that other people can in time receive teller's voice messaging when a people talks, therefore the synchronism that voice messaging is arrived each MS requires very high.But in the prior art, at first, PTT Server by and RAN between the dedicated link of each MS the voice messaging that duplicates is sent respectively, because the speed difference of each MS dedicated link transmitting voice information, therefore, from PTT Server to RAN the time, there is one time transmission time difference.When the dedicated link of RAN by each MS sends to each MS respectively with voice messaging, because there is transmission time difference again one time in the difference of transmission link.And, when if RAN inside comprises a plurality of network entity, per two network entities of this RAN inside are the dedicated link transmitting voice information by each MS all, therefore all there is transmission time difference one time between these per two network entities, and network entity is many more, and voice messaging is just big more in the transmission time of RAN inside difference.Therefore, when the contact of RAN inner tight, when not comprising a plurality of network entity, there is transmission time difference twice in prior art when transmitting voice information, when RAN inside comprises a plurality of network entity, there is transmission time difference at least three times in prior art when transmitting voice information, and, the network entity of RAN inside is many more, transmission time difference is just big more, so it is very big to cause teller's voice messaging to arrive time interval of each MS, thereby be unfavorable for realizing the synchronism of each MS receiving speech information.
3, in the prior art, PTT Server need duplicate a voice messaging for each MS except that the MS that obtains speaking right, and the voice messaging branch that duplicates is sent out by the dedicated link of each MS, so when the One's name is legion of MS, then processing speed and the disposal ability to PTT Server proposed higher requirement, and then increased the cost of cluster network.
Summary of the invention
In view of this, main purpose of the present invention is to provide a kind of method that realizes press-and-talk business, makes its conserve network resources greatly.
In order to achieve the above object, technical scheme of the present invention is achieved in that
A kind of method that realizes press-and-talk business, when the MS for first access RAN in the group connects, between this RAN and cluster server, set up the shared link of this group, when follow-up MS inserts by this RAN in this group, the shared link of being set up is set to the transmission link of follow-up MS between this RAN and cluster server in this group, and this method is further comprising the steps of:
The MS that makes a speech in A, the described group sends to the RAN that self inserts with business information, and this RAN is sent to cluster server by the shared link of described group with business information;
B, cluster server are according to the quantity duplication service information of the shared link of described group between self and the RAN that have set up, and each the bar shared link by described group sends to all RAN that MS inserts in the described group with the business information of duplicating then;

When described RAN inside comprised a plurality of network entity, this method further comprised: when the MS for first access RAN in the described group connects, set up the shared link of this group between per two network entities that directly link to each other of this RAN inside;
Steps A comprises: the MS that makes a speech in the described group sends to business information the network entity that the RAN inside self inserted and this MS directly link to each other, after should receiving business information with the network entity that MS directly links to each other, by the shared link of inner this group that sets up of this RAN with business information transfer to this RAN inner with the direct-connected network entity of cluster server, should and the direct-connected network entity of cluster server by the shared link of this group between this RAN and the cluster server business information is sent to cluster server again;
Step C comprises: the RAN inside that MS inserts in described group, the network entity that receives the business information that cluster server sends by at the inner shared link of setting up of this RAN business information is transferred to this RAN inner with this group in the direct-connected network entity of MS, should again business information be sent to MS in this group with the direct-connected network entity of MS.
When described press-and-talk business was applied in the CDMA systems, what set up between inner per two network entities that directly link to each other of RAN was sharing A 8 links.
When described RAN inside comprises base station controller BSC and two network entities of Packet Control Function entity PCF, and BSC directly links to each other with MS, when PCF directly links to each other with cluster server,
Steps A comprises: the MS that makes a speech in the described group sends to business information the BSC that self inserts, this BSC transfers to PCF by sharing A 8 links with business information, this PCF again by and cluster server between the shared link of this group business information is sent to cluster server;
Step C comprises: PCF receives the business information that cluster server is sent, and by sharing A 8 links business information is transferred to BSC, and BSC sends to business information the MS in this group again.
When described press-and-talk business was applied in the cdma system, what set up between RAN and cluster server was to share the GMP link.
After RAN described in the step C receives business information, duplicate and distribution service information according to the quantity of the MS by its access in this group.
Behind the end of calling of described group, this method further comprises: be released to all links that MS set up in this group.

Fig. 5 is a kind of cluster network schematic diagram of realizing the PTT business in the present invention.Below in conjunction with cluster network structure shown in Figure 5, illustrate how the present invention sets up each MS to the link of PTT Server and realize the PTT business.
Referring to Fig. 5, MS1 belongs to same group to MS5, is designated as group 1.MS1 and MS2 are by RAN1 access set group network, and RAN1 is integrated entity, and MS3, MS4 and MS5 are by RAN2 access set group network, and RAN2 inside comprises BSC and two network entities of PCF.
Fig. 6 sets up the flow chart of each MS to PTT Server link in the present invention.Referring to Fig. 5 and Fig. 6, in the present invention, when the call setup of group 1, insert successively to MS5 such as MS1, the present invention sets up each MS in the group 1 and may further comprise the steps to the detailed process of PTT Server link so:
Step 601:MS1 inserts, and sets up the dedicated link A of MS1 between MS1 and the RAN1, and set up a shared link M1 between RAN1 and PTT Server.
Step 602:MS2 inserts, and sets up the dedicated link B of MS2 between MS2 and the RAN1, and directly shared link M1 is set to the link of MS2 between RAN1 and PTT Server.
Here, because MS1 and MS2 belong to same group 1, all by RAN1 access set group network, and, between RAN1 and PTT Server, set up shared link M1, so no longer be that MS2 is based upon the link between RAN1 and the PTT Server separately.
Step 603:MS3 inserts, and sets up the dedicated link C of MS3 between MS3 and the RAN1, and sets up a shared link M2 between the BSC of RAN2 inside and PCF, sets up a shared link M3 then between RAN2 and PTT Server.
Step 604:MS4 inserts, and sets up the dedicated link D of MS4 between MS4 and the RAN2, and directly shared link M2 is set to the link of MS4 in RAN2 inside, and shared link M3 is set to the link of MS4 between RAN2 and PTT Server.
Here, because MS4 and MS3 belong to same group 1, all by RAN2 access set group network, and, between the BSC of RAN2 inside and PCF, set up shared link M2, between RAN2 and PTT Server, also set up shared link M3, so, no longer be that MS4 sets up the link between RAN2 inside or RAN2 and the PTT Server separately.
Step 605:MS5 inserts, and sets up the dedicated link E of MS5 between MS5 and the RAN2, and directly shared link M2 is set to the link of MS5 in RAN2 inside, and shared link M3 is set to the link of MS5 between RAN2 and PTT Server.
Here, because MS5 belongs to same group 1 with MS3 and MS4, all by RAN2 access set group network, and, between the BSC of RAN2 inside and PCF, set up shared link M2, between RAN2 and PTT Server, also set up shared link M3, so, no longer be that MS5 sets up the link between RAN2 inside or RAN2 and the PTT Server separately.
So far, the present invention sets up the link of each MS in the group 1 that is over.Relevant link and group information then can be preserved in RAN1, RAN2 and PTT Server inside.Such as,
RAN1 preserves inside: group's group number is a group 1, and the MS of access is MS1 and MS2, and link A and link B are respectively the dedicated link of MS1 and MS2, and shared link M1 is the transmission link of group 1 between RAN1 and PTT Server.RAN2 preserves inside: group's group number is a group 1, the MS that inserts is MS3, MS4 and MS5, link C, link D and link E are respectively the dedicated link of MS3, MS4 and MS5, and shared link M2 and shared link M3 are respectively the transmission link of MS between RAN2 inside and RAN2 and PTT Server in the group 1.PTT Server preserves inside: group group number be group 1, the MS of access be MS1 to MS5, shared link M1 is the transmission link of group 1 between RAN1 and PTT Server, shared link M3 is the transmission link of group 1 between RAN2 and PTT Server.
Fig. 7 is the flow chart of the present invention's transmission MS voice messaging when realizing Prepaid ﹠ Postpaid Telephony Service.Referring to Fig. 5 and Fig. 7, obtaining speaking right with MS5 is example, utilizes the link of each MS in the group 1 that is set up, and the detailed process of the present invention's voice messaging of transmission MS5 when realizing that PTT is professional may further comprise the steps:
To be link E by its dedicated link send to RAN2 with self voice messaging to step 701:MS5.
BSC among the step 702:RAN2 receives voice messaging, by shared link M2 this voice messaging is sent to PCF.
Here, after BSC among the RAN2 receives voice messaging by link E, relevant link and group information according to the inside preservation, be that link E is the dedicated link of MS5, MS5 belongs to group 1, and know that voice messaging is to be sent by the MS5 in the group 1, and therefore, by being the shared link M2 transmission voice messaging that group 1 sets up.
Step 703:PCF sends to PTTServer with the voice messaging that receives by shared link M3 again.
After step 704:PTT Server receives voice messaging, this voice messaging is duplicated 2 parts send to RAN1 and RAN2 by shared link M1 and shared link M3 respectively.
Here, PTT Server receives voice messaging by shared link M3, according to the relevant link and the group information of inside preservation, be that shared link M3 is the transmission link of group 1, also comprise MS1 in the group 1 to MS4, therefore, PTT Server is the MS copying voice information in the group 1.And PTT Server duplicates voice messaging according to the quantity of the shared link of being set up.Owing between RAN1 and PTT Server, have shared link M1, between RAN2 and PTT Server, there is shared link M3, promptly there are 2 shared links, therefore, PTT Server only needs the voice messaging that receives is duplicated 2 parts.
After step 705:RAN1 receives voice messaging, this voice messaging is duplicated 2 parts also send to MS1 and MS2 by link A and link B respectively.
In RAN2 inside, after PCF receives voice messaging, this voice messaging is sent to BSC by shared link M2, BSC duplicates 3 parts with the voice messaging that receives and sends to MS3, MS4 and MS5 respectively by link C, link D and link E.
Here, because BSC receives voice messaging by shared link M2, BSC distinguishes the purpose MS of voice messaging by dedicated link can't be in prior art, therefore BSC also can duplicate concurrent sending voice information for MS5, MS5 can avoid causing echo by not receiving or not playback shields the voice messaging that this is sent by self.
So far, MS1 has realized the PTT business to the voice messaging that MS4 receives MS5.
If the MS in a plurality of groups is by same RAN access set group network, and carry out the PTT business simultaneously, in the present invention, the voice messaging that relevant link that RAN and PTT Server preserve according to inside and group information are distinguished each group.Fig. 8 is two groups schematic diagram of access set group networks simultaneously in the present invention.Below, be example with network configuration shown in Figure 8, illustrate how the present invention is embodied as different groups the PTT business is provided simultaneously.
Referring to Fig. 8, such as when the PTT of group 1 business is carried out, the call setup of group 2, terminal MS 6 in the group 2 and MS7 are by RAN1 access set group network successively, then to set up the link Principle of Process of each MS in the group 1 identical with the invention described above, when the present invention inserts at MS6, between MS6 and RAN1, set up the dedicated link of link F, and between RAN1 and PTT Server, set up a shared link N1 as MS6.When MS7 inserts, between MS7 and RAN1, set up the dedicated link of link G, and directly shared link N1 is set to the link of MS7 between RAN1 and PTTServer as MS7.
Correspondingly, the inner and inner relevant information of preserving group 2 of PTT Server of RAN1.Such as, RAN1 preserves inside: group's group number is a group 2, and the MS of access is MS6 and MS7, and link F and link G are respectively the dedicated link of MS6 and MS7, and shared link N1 is the transmission link of group 2 between RAN1 and PTT Server.Preserve in PTT Server inside: group's group number is a group 2, and the MS of access is MS6 and MS7, and shared link N1 is the transmission link of group 2 between RAN1 and PTT Server.
Therefore, when the PTT of group 1 business is carried out, if the voice messaging of a MS in the group 2, voice messaging such as MS6, when arriving RAN1 by link F, RAN1 knows that according to link F that receives voice messaging and the inner relevant group information of preserving this voice messaging is to be sent by the MS6 in the group 2, then by the shared link N1 that sets up for group 2 this voice messaging is sent to PTT Server; PTT Server knows that according to shared link N1 that receives voice messaging and inner relevant information of preserving this voice messaging is to be sent by the MS in the group 2, then by the shared link N1 that sets up for group 2 voice messaging that duplicates is sent to RAN1; RAN1 is known that this voice messaging should send to each MS in the group 2, thereby is finished distribution by shared link N1 that receives voice messaging and inner relevant information of preserving, realizes the PTT business of group 2.
For saving Internet resources, after the PTT of group service ending, the present invention is released to all links of the MS foundation of this group.
In the present invention, when above-mentioned PTT service application is in code division multiple access (CDMA) system, inner all shared links set up of RAN2 can be sharing A 8 links, and all shared links of setting up between RAN1 or RAN2 and PTT Server can be to share the GMP link.
