At first, Fig. 1 is the block diagram of the mobile communications network of first embodiment of the invention.
With reference to Fig. 1, the mobile communication terminal 10 of first embodiment of the invention is to have to support asynchronous mobile communiation service and synchronous mobile communication to serve DBDM (DBDM) mobile communication terminal of the ability of the two, and mobile communication terminal 10 comprises synchronous modem at the synchronous mobile communication service, at the asynchronous modem controller and the shared module of asynchronous mobile communiation service.Therefore, mobile communication terminal 10 can connect asynchronous mobile communiation system 20 or synchronous mobile communication system 30, so that use the voice-and-data service that they provide.
Asynchronous mobile communiation system 20 comprises Node B/RNC 210, asynchronous mobile switching centre (MSC) 220, GPRS (GPRS) network 240, service type GPRS Support Node (SGSN) 230 and Gateway GPRS Support Node (GGSN) 250.Node B/RNC 210 representative be used to support the radio communication of carrying out with mobile communication terminal 10 the base station Node B or be used for Control Node B and mobile communication terminal 10 carries out the RNC (radio network controller) 210 of radio communication.Asynchronous mobile switching centre 220 links to each other with Node B/RNC 210, and calls out exchange by Node B/RNC 210 with mobile communication terminal 10, so that provide service to mobile communication terminal 10.SGSN 230 is connected between Node B/RNC 210 and the GPRS network 240, with position and execution access control and the security function that continues tracing mobile commutation terminal 10.GGSN 250 links to each other with SGSN 230 and links to each other with IP network 70 by GPRS network 240, with the intercommunication of supporting to divide into groups with the external system exchange.
Synchronous mobile communication system 30 comprises BTS/BSC 310, synchronous mobile switching centre 320, PDSN 330 and data core network (DCN) 340.BTS/BSC 310 representative is used to support the BTS (base transceiver machine station) of the radio communication of carrying out with mobile communication terminal 10 or is used to control BTS and mobile communication terminal 10 carries out the BSC (base station controller) of radio communication.Synchronously mobile switching centre 320 link to each other with at least one BSC and with its switched call.PDSN 330 links to each other with BSC, is used for providing packet data service to the user.DCN 340 supports being connected between PDSN 330 and the IP network 70.
Asynchronous mobile switching centre 220 and synchronous mobile switching centre 320 are interconnective by No.7 global semaphore network 40, and they link to each other with two stack home location registers (D-HLR) 50 by this No.7 global semaphore network 40.The asynchronous mobile communiation system user profile and the corresponding synchronous mobile communication system user information of two stack home location register 50 storages and management DB DM mobile communication terminal 10, thus make asynchronous mobile switching centre 220 and synchronous mobile switching centre 320 when carrying out the work such, to consult these information such as handing-over.
In the network of the structure of on have, introducing, be in mobile communication terminal 10 in the service area of asynchronous mobile communiation system 20 and periodically measure, and measured intensity is reported to serving node B from the intensity of the signal of the serving node B of mobile communication terminal 10 current connections with from the intensity of the signal of the adjacent node Bs adjacent with serving node B.When the intensity from the signal of serving node B was lower than predetermined threshold, serving node B took place to asynchronous mobile switching centre 220 report handing-over incidents by RNC.In this case, Node B/RNC 210 sends to asynchronous mobile switching centre 220 with this report together with the information by mobile communication terminal 10 detected contiguous emitter regions, base station IDs etc.
When receiving handover request message from RNC, asynchronous mobile switching centre 220 with reference to from contiguous emitter region that RNC receives, judgements such as the base station IDs handing-over of asking be asynchronous mobile communiation system 20 interior be close between the emitter regions handing-over or to the handing-over of synchronous mobile communication system 30.When the handing-over of being asked was the handing-over that is close between the emitter region, then asynchronous mobile switching centre 220 was close to the handing-over between the emitter region.On the contrary, when the handing-over of being asked was handing-over to synchronous mobile communication system 30, asynchronous mobile switching centre 220 and operation between mobile switching centre 320 nets synchronously were to carry out the handing-over to synchronous mobile communication system 30.
Hereinafter, introduce the processing procedure of handing-over in detail with reference to Fig. 2.
Fig. 2 is the flow chart of the processing procedure that joins between asynchronous network and synchronizing network of first embodiment of the invention.
With reference to Fig. 2, along with the mobile communication terminal 10 that carries out voice communication in the service area of asynchronous mobile communiation system 20 moves to the service area of synchronous mobile communication system 30, mobile communication terminal 10 detects from the signal of synchronous mobile communication system 30, periodically measure from the intensity of the signal of the current service Node B of asynchronous mobile communiation system 20 and neighbor base station (Node B s) and to the measured intensity of current service Node B report.When the intensity from the signal of the current service Node B of mobile communication terminal 10 current connections was lower than predetermined value, mobile communication terminal 10 sent handover request message (IU-Reloc Required) (step S101) by RNC to asynchronous mobile switching centre 220.
This handover request message (IU Reloc Required) comprises the handing-over related news that are used in the synchronous mobile communication system.Here, RNC will send to asynchronous mobile switching centre 220 with handover request message from contiguous emitter region information that mobile communication terminal 10 receives, neighbor base station information (contiguous Bs ID) etc.According to this information, asynchronous mobile switching centre 220 judge the handing-over of being asked be between the contiguous emitter region in the asynchronous mobile communiation system 20 handing-over or to the handing-over of synchronous mobile communication system 30.
When receiving handover request message, asynchronous mobile switching centre 220 sends handing-over Indication message (Facilities Directive2) (step S102) to synchronous mobile switching centre 320.Then, mobile switching centre 320 sends handover request message (HandoffRequest) (step S103) to BTS/BSC 310 synchronously.
Sending handing-over Indication message (Facilities Directive2) before to synchronous mobile switching centre 320, asynchronous mobile switching centre 220 produces charging identifier (ID) and is inserted in handing-over Indication message (Facilities Directive2).And asynchronous mobile switching centre 220 will join region corresponding inner exchanging central circuit ID (InterMSCCircuitID) with each and be inserted in the handing-over Indication message (Facilities Directive2) that is sent.Charging ID comprises the ID of the synchronous mobile switching centre 320 that asynchronous mobile switching centre 220 will connect.
When receiving the handover request message of motor synchronizing mobile switching centre 320, BTS/BSC310 sends empty frame (empty forward communication channels frame) by downlink communication channel to the synchronous modem of mobile communication terminal 10, thereby realizes the distribution (step S104) of downlink channel.Then, BTS/BSC 310 sends response message (Handoff Request Ack) (step S105) in response to the handover request message of coming motor synchronizing mobile switching centre 320 to synchronous mobile switching centre 320.Then, mobile switching centre 320 sends response message (FacilitiesDirective2 Ack) (step S106) in response to the handing-over Indication message from asynchronous mobile switching centre 220 to asynchronous mobile switching centre 220 synchronously.As a result, asynchronous mobile switching centre 220 and the synchronous trunk line between the mobile switching centre 320 have been set up.
More specifically, asynchronous mobile switching centre 220 is provided with physical relay line and as the mapping relations between the dedicated channel of the identifier that is used to set up logical trunk, this information setting is sent to synchronous mobile switching centre 320 for the inner exchanging central circuit ID (InterMSCCircuitID) of handing-over Indication message (Facilities Directive2) and with set ID.After this, when response message (Facilities Directive2 Ack) when synchronous mobile switching centre 320 sends, just set up asynchronous mobile switching centre 220 and the trunk line between the mobile switching centre 320 synchronously.The handing-over Indication message (Facilities Directive2) that transmits between asynchronous mobile switching centre 220 and synchronous mobile switching centre 320 comprises the parameter such as charging ID, ESN, inner exchanging center ID and MIN, and its response message (Facilities Directive2Ack) comprises the parameter such as CDMA Channel data and CDMA Channel tabulation.
After the trunk line of having set up in the mode of introducing above between the switching center, asynchronous mobile switching centre 220 finishes (IURelocation order) (step S107) to Node B/RNC 210 reports at the resource allocation of handing-over.When receiving this report (IU Relocation order), the asynchronous modem controller of Node B/RNC 210 indication mobile communication terminals 10 is carried out handing-over (Handover from UTRAN order) (step S108).
After this, the asynchronous modem controller of mobile communication terminal 10 is to synchronous modem transmitting channel assignment information (Channel Assigment) (step S109).The synchronous modem of mobile communication terminal 10 is finished (step S111) by uplink communication channel to the BTS/BSC of synchronous mobile communication system 310 transmit frames or lead code (Reverse Traffic Channel Frame or Traffic ChannelPreamble) (step S110) and report (Handoff Completion message) handing-over.When receiving this report (Handoff Completion message), BTS/BSC 310 sends response signal (BS Ack Order) (step S112) in response to this report.Then, synchronous modem has been set up fully with the calling of synchronous mobile communication system to the asynchronous modem controller report and has been connected (step S113).
Simultaneously, BTS/BSC 310 finishes (Handoff Complete) (step S114) to the 320 report handing-over of synchronous mobile switching centre, and mobile switching centre 320 finishes (Mobile On Channel) (step S115) to the 220 report handing-over of asynchronous mobile switching centre synchronously.Then, the asynchronous 220 requesting node B/RNC 210 of mobile switching centre remove this connection (IU Release order) (step S116).When asynchronous mobile switching centre 220 receives when removing the response (IU Release Complete) that request makes, remove be connected (the step S117) between asynchronous mobile switching centre 220 and the Node B/RNC210.
In the service area of having finished according to the processing procedure of introducing above at asynchronous mobile communiation system, carry out after the handing-over of mobile communication terminal in synchronous mobile communication system of voice communication, come call disestablishment to connect (step S118) by request (Facilities Release, Facilities Ack) from one of two mobile communication terminals.
The handing-over of introducing above can carrying out when correctly having exchanged message error-free between mobile switching centre and the asynchronous mobile switching centre is synchronously handled.In other words, synchronously mobile switching centre and asynchronous mobile switching centre are undertaken interconnectively by the tie trunk that is used to join, and can provide high quality services to the user when trunk line is correctly worked.
In order to check whether trunk line works really correctly, mobile switching centre and asynchronous mobile switching centre use circuit replacement message (ResetCircuit), circuit interruption message (Blocking), circuit interruption to remove message, trunk line test post (TrunkTest) and trunk line test and remove message synchronously.Will call ' trunk line administrative messag ' to above-named these message in the present invention.Asynchronous mobile switching centre or synchronously mobile switching centre to after making response from the call (paging) of the other side mobile switching centre, it sends the trunk line administrative messag to the other side mobile switching centre, receives the response that this trunk line administrative messag is made then.So the state of trunk line can obtain confirming.
In other words, in asynchronous mobile switching centre and the synchronous mobile switching centre any one can at first send the trunk line administrative messag to the other side when it is in the state of calling, and the other side sends the response that received trunk line administrative messag is made.So the mobile switching centre that at first sends the trunk line administrative messag can confirm the state of trunk line.
Fig. 3 is to be used for the state of the special use handing-over trunk line between the mobile switching centre is confirmed in graphic extension by transmission/reception trunk line administrative messag method and the view that is used to show the tabulation of the parameter that is included in each trunk line administrative messag to Figure 11.In the present embodiment, will asynchronous mobile switching centre at first to synchronous mobile switching centre send the trunk line administrative messag and synchronously mobile switching centre send this situation of response that received trunk line administrative messag is made then and come as an example to be discussed.
Fig. 3 and Fig. 4 are the views that is used for being presented in the circuit replacement message (ResetCircuit) that the method for the trunk line between the management mobile switching centre of first embodiment of the invention uses.As shown in Figure 3, when asynchronous mobile switching centre uses asynchronous mobile switching centre and synchronously goes to pot circuit in the trunk line between the mobile switching centre or for the state information of reproducing destroyed circuit and replacement at needs, use circuit replacement message (ResetCircuit).When receiving circuit replacement message (ResetCircuit), mobile switching centre sends the response message (ResetCircuit Ack) of the state information that comprises trunk line to asynchronous mobile switching centre synchronously.
As shown in Figure 4, circuit replacement message (ResetCircuit) comprises the parameter (InterMSCCircuitID) corresponding to inner exchanging central circuit ID, and response message (ResetCircuit Ack) comprises the parameter (TrunkState) corresponding to trunk state information.
Fig. 5 is to be used for being presented in the view that circuit interruption message (Blocking) that the method for the trunk line between the management mobile switching centre of first embodiment of the invention uses and circuit interruption are removed message to Fig. 8.
With reference to Fig. 5, in order to report that the trunk line that is distributed between the mobile switching centre is interrupted, in other words, when the connection between the unnecessary maintenance mobile switching centre, asynchronous mobile switching centre is to synchronous mobile switching centre's transtation mission circuit interrupt message (Blocking), and mobile switching centre sends response message (Blocking Ack) to asynchronous mobile switching centre synchronously.
With reference to Fig. 7, when the connection between the mobile switching centre is interrupted by circuit interruption message (Blocking), asynchronous mobile switching centre is to synchronous mobile switching centre's transtation mission circuit replacement message (Unblocking), so that trunk line is switched to upstate, and synchronous mobile switching centre sends the response message (Unblocking Ack) at circuit replacement message (Unblocking).
As shown in Figure 6, circuit interruption message (Blocking) comprises the parameter (InterMSCCircuitID) of representing inner exchanging central circuit ID, and as shown in Figure 8, circuit replacement message (Unblocking) also comprises the parameter (InterMSCCircuitID) of representing inner exchanging central circuit ID.
Fig. 9 is the view that is used for describing the trunk line test post (TrunkTest) that the method for the trunk line between the management mobile switching centre of first embodiment of the invention uses to Figure 11.
As shown in Figure 9, whether correctly work in order to check trunk line, asynchronous mobile switching centre sends trunk line test post (TrunkTest) to synchronous mobile switching centre, and mobile switching centre sends response message (TrunkTest Ack) to asynchronous mobile switching centre synchronously.
When the test that needs finish trunk line is carried out, asynchronous mobile switching centre sends the trunk line test to synchronous mobile switching centre and removes message (TrunkTestDisconnect), and mobile switching centre sends response message (TrunkTestDisconnectAck) to asynchronous mobile switching centre synchronously.
As shown in figure 10, trunk line test post (TrunkTest) comprises and is used for inner exchanging central circuit ID (InterMSCCircuitID) and the parameter of the line is busy type (SeizureType), and as shown in figure 11, trunk line test releasing message (TrunkTestDisconnect) comprises the parameter corresponding to inner exchanging central circuit ID (InterMSCCircuitID).
What top specification was discussed is by using MAP at first to send the situation of trunk line administrative messag to synchronous mobile switching centre from asynchronous mobile switching centre.But, also can be with opposite mode supervisory relay line, promptly mobile switching centre at first sends the trunk line administrative messag and receives response message from asynchronous mobile switching centre then to asynchronous mobile switching centre synchronously.In addition, except the parameter shown in the figure, according to the function expansion of carrying out between the mobile switching centre, each trunk line administrative messag can also comprise other parameter.

In the network of the structure of on have, introducing, be in mobile communication terminal 410 in the service area of asynchronous mobile communiation system 420 and periodically measure, and measured intensity is reported to serving node B from the intensity of the signal of the serving node B of mobile communication terminal 410 current connections with from the intensity of the signal of the adjacent node Bs adjacent with serving node B.When the intensity from the signal of serving node B was lower than predetermined threshold, serving node B was by the generation of RNC to asynchronous mobile switching centre 620 report handing-over incidents.In this case, Node B/RNC 610 sends to asynchronous mobile switching centre 620 with this report with the information by mobile communication terminal 410 detected contiguous emitter regions, base station IDs etc.
When the handover request message that receives from RNC, asynchronous mobile switching centre 620 with reference to from contiguous emitter region that RNC receives, judgements such as the base station IDs handing-over of asking be asynchronous mobile communiation system 420 interior be close between the emitter regions handing-over or to the handing-over of synchronous mobile communication system 430.
When being close to the handing-over between the emitter region in the handing-over of being asked is asynchronous mobile communiation system 420, asynchronous mobile switching centre 620 is close to the handing-over between the emitter region.On the contrary, when the handing-over of being asked is handing-over to synchronous mobile communication system 430, the handing-over that asynchronous mobile switching centre 620 carries out to synchronous mobile communication system 430 IIF unit 460.In order to join, IIF unit 460 asynchronous message is converted to synchronization message and will change after synchronization message send to synchronous mobile switching centre 720.In order to carry out this operation, need IIF unit 460 to work out and manage the synchronous mobile communication system database of information in advance.This database comprises the information, signaling point of switching center, information of the trunk line relevant with dedicated channel etc.According to synchronous mobile communication system information with from the handover request of asynchronous mobile switching centre 620, the target that 460 selections of IIF unit will be handed off to, in other words, mobile switching centre 620, and produce the charging ID of the ID that comprises handing-over target mobile switching centre, this charging ID can obtain using in handing-over is after this handled.
Hereinafter, introduce the processing procedure of handing-over in detail with reference to Figure 13.
Figure 13 is the flow chart of the processing procedure that is used for the handing-over between asynchronous network and the synchronizing network second embodiment of the invention.
With reference to Figure 13, when the mobile communication terminal 410 that carries out voice communication in the service area of asynchronous mobile communiation system 420 moved to the service area of synchronous mobile communication system 430, mobile communication terminal 410 detected from the signal of synchronous mobile communication system 430, periodically measure from the intensity of the signal of the current service Node B of asynchronous mobile communiation system 420 and neighbor base station (Node B s) and with measured intensity and report to the current service Node B.When the intensity from the signal of the current service Node B of mobile communication terminal 410 current connections was lower than predetermined value, mobile communication terminal 410 sent handover request message (IU-Reloc Required) (step S501) by RNC to asynchronous mobile switching centre 620.
This handover request message (IU Reloc Required) comprises the message of using in the synchronous mobile communication system relevant with handing-over.Here, RNC will send to asynchronous mobile switching centre 620 with handover request message from contiguous emitter region information that mobile communication terminal 410 receives, neighbor base station information (contiguous BS ID) etc.According to this information, asynchronous mobile switching centre 620 judges that the handing-over of being asked is the handing-over between the contiguous emitter regions or to the handing-over of synchronous mobile communication system 430 in the asynchronous mobile communiation system 420.The handover request message (IU Reloc Required) that sends to asynchronous mobile switching centre 620 from RNC comprises the parameter such as type of message, type of handover, handing-over reason, source base station controller ID, target base station controller ID, radio access carrier (RAB) information and wireless region related information.In addition, RNC is added to the parameter that is included in the handover request message ' on the Old BSS ToNew BSS Information ' with what use in the synchronous mobile communication system with the relevant information of handing-over.
When receiving handover request message, asynchronous mobile switching centre 620 sends the asynchronous message (MAP Prep Handover Req) (step S502) of request handing-over to IIF unit 460.Here, extension container is added on the asynchronous message, then the asynchronous identifier (MSISDN) of this asynchronous message with mobile communication terminal 410 is sent.This asynchronous message comprises the parameter such as calling ID, Target Launch Zone ID, target radio network controller ID and MSISDN.
After this, by consulting the async user's information (MSISDN) that receives from asynchronous mobile switching centre 220, IIF unit 460 request D-HLR 450 send user profile (Call DataRequest) (step S503).In other words, and the synchronizing network identifier of IIF unit 460 request mobile communication terminals 410 (MIN, ESN).In step S503, IIF unit 460 can be by using the synchronous network identifier information of asynchronous message (MAP_SEND_IMSI) to D-HLR 450 request users.
When the request that receives user profile, D-HLR 450 consults database, (MIN ESN) and then sends to the information of being extracted IIF unit 460 (Call Data Req Ack) (step S504) to extract the synchronous network identifier information of relative users.Here, the synchronizing network message (Call Data Req) of request user's synchronous network identifier information comprises such as the charging ID sum digit (promptly, MSISDN) and so on parameter, and response message (Call Data Req Ack) comprises the message such as ESN, MIN and MSCID.Simultaneously, when using asynchronous message (MAP_SEND_IMSI) in the process of the synchronous network identifier information of asking the user, asynchronous message (MAP_SEND_IMSI) comprises the parameter such as calling ID, MSISDN, IMSI and ESN.
When D-HLR 450 receives user profile, IIF 460 indications (FacilitiesDirective2) join (step S505) to synchronous mobile switching centre 720, and mobile switching centre 720 sends handover request message (Handoff Request) (step S506) to BTS/BSC 710 synchronously.
Sending handing-over Indication message (Facilities Directive2) before to synchronous mobile switching centre 720, IIF unit 460 produces charging identifier (ID) and is inserted in handing-over Indication message (Facilities Directive2).And IIF unit 460 is inserted into inner exchanging central circuit ID (InterMSCCircuitID) in the handing-over Indication message (FacilitiesDirective2) that is sent.Charging ID comprises the ID of the synchronous mobile switching centre 720 that asynchronous mobile switching centre 620 will connect.
When synchronous mobile switching centre 720 receives handover request message, BTS/BSC 710 sends empty frame (Forward Traffic Channel frame) by downlink communication channel to the synchronous modem of mobile communication terminal 410, thereby realizes the distribution (step S507) of downlink channel.Then, BTS/BSC 710 sends response message (Handoff Request Ack) (step S508) in response to the handover request message of coming motor synchronizing mobile switching centre 720 to synchronous mobile switching centre 720.Then, synchronous mobile switching centre 720 sends response messages (Facilities Directive2 Ack) (step S509) in response to the handing-over Indication message of step S502 to asynchronous mobile switching centre 620.As a result, asynchronous mobile switching centre 620 and the synchronous trunk line between the mobile switching centre 720 have been set up.
More specifically, IIF unit 460 is provided with physical relay line and as the mapping relations between the dedicated channel of the identifier that is used to set up logical trunk, this information setting is sent to synchronous mobile switching centre 720 for the inner exchanging central circuit ID (InterMSCCircuitID) of handing-over Indication message (Facilities Directive2) and with set ID.After this, when having sent response message (Facilities Directive2 Ack) from synchronous mobile switching centre 720, just set up the trunk line between asynchronous mobile switching centre 620 and the synchronous mobile switching centre 720.The handing-over Indication message (Facilities Directive2) that sends between asynchronous mobile switching centre 620 and synchronous mobile switching centre 720 comprises the parameter such as charging ID, ESN, inner exchanging central circuit ID and MIN, and its response message (Facilities Directive2 Ack) comprises the parameter such as CDMA Channel data and CDMA Channel tabulation.
After this, asynchronous mobile switching centre 620 sends initial address message (IAM) to IIF unit 460, and IIF unit 460 sends AC address complete message (ACM) in response to this IAM, thereby between asynchronous mobile switching centre 620 and synchronous mobile switching centre 720, be provided with trunk line, and can carry out Route Selection (route) (step S511 and S512) to calling by this trunk line.The message that is used for the trunk line setting between the mobile switching centre is by ISUP transmission/reception.
After the trunk line that is provided with in the mode of introducing above between the switching center, asynchronous mobile switching centre 620 finishes (IURelocation order) (step S513) to Node B/RNC 610 reports at the resource allocation of handing-over.When receiving this report (IU Relocation order), the asynchronous modem controller of Node B/RNC 610 request mobile communication terminals 410 is carried out handing-over (Handover from UTRAN order) (step S514).Here, report comprises the parameter that comprises that type of message, RRC container, the RAB that will remove tabulate etc. at the message (IU Relocation order) finished of resource allocation of handing-over.
After this, the asynchronous modem controller of mobile communication terminal 410 is to synchronous modem transmitting channel assignment information (step S515), and IIF unit 460 inserts signal (MAP Process Access Signaling Req) (step S516) to 620 requests of asynchronous mobile switching centre.This access signal comprises and calls ID, Application Protocol Data Unit (APDU), selected radio resource information etc.
In addition, the synchronous modem of mobile communication terminal 410 is finished (step S518) by uplink communication channel to the BTS/BSC of synchronous mobile communication system 710 transmit frames or lead code (step S517) and report (Handoff Completion Message) handing-over.When receiving this report (Handoff Completion Message), BTS/BSC 710 sends response signal (BS Ack Order) (step S519) in response to this report.Then, synchronous modem has been set up fully with the calling of synchronous mobile communication system to the asynchronous modem controller report and has been connected (step S520).
Then, BTS/BSC 710 finishes (step S521) to 720 report (HandoffComplete) handing-over of synchronous mobile switching centre, and synchronously mobile switching centre 720 to the IIF unit 460 report (Mobile On Channel) handing-over finish (step S522).When receiving this report, 460 requests asynchronous mobile switching centre 620 in IIF unit removes and connects (MAP SendEnd Signal Req) (step S523).
In addition, IIF unit 460 sends report mobile communication terminal and the message (ANSWER) (step S524) that is connected between the mobile switching centre 720 synchronously to asynchronous mobile switching centre 620.Then, will be connected releasing (IURelease order, IU Release Complete) (step 525 and 526) between asynchronous mobile switching centre 620 and the Node B/RNC 610.
