Below in conjunction with Figure of description, each embodiment of the present invention is described in detail.
Embodiment one:
As shown in Figure 1, for the schematic flow sheet of the method for a kind of paging terminal called of the embodiment of the present invention one, in the scene that when embodiment of the present invention one is applied in calling terminal paging terminal called, terminal called occurrence positions switches, the MSC that the embodiment of the present invention one relates to is MSC affiliated before terminal called carries out position switching, the 2nd MSC is MSC affiliated after terminal called carries out position switching.Described method comprises:
Step 101: the first moving exchanging center MSC receives the location change message that the second moving exchanging center MSC sends.
Wherein, the address information of the identification information of terminal called and described 2nd MSC belonging to described terminal called is carried in described location change message.
In a step 101, terminal called is registered in a described MSC, when this terminal called called, the MSC address information that Visited Location Registor HLR registers according to terminal called, PRN(Provide Roaming Number is sent to a described MSC, roaming data is provided) instruction, and receive the PRN ACK instruction that a described MSC returns.
The PRN ACK instruction that described HLR is receiving a described MSC and returns, returns SRI ACK to GMSC; Described GMSC sends MSRN message according to the described SRI ACK received to a described MSC.
A described MSC, when receiving described MSRN message, according to the network formats of the communication network at the current place of terminal called, selects suitable interface to send beep-page message to described terminal called.
Particularly, when the network formats of the communication network at the current place of terminal called is GERAN, send beep-page message by A interface to described terminal called;
When the network formats of the communication network at the current place of terminal called is UTRAN, send beep-page message by Iu interface to described terminal called;
When the network formats of the communication network at the current place of terminal called is E-UTRAN, send beep-page message by SGs interface to described terminal called.
Now, when the MSC belonging to described terminal called changes, the 2nd MSC is changed to by a MSC, so now terminal sends position to the 2nd MSC after change and changes message, wherein, the address information that the identification information that carries described terminal called in message and described terminal called are registered in the first moving exchanging center MSC in Visited Location Registor HLR is changed in described position.
Such as: TMSI and the old LAI carrying terminal called and be assigned with is changed in message in described position.
It should be noted that, send in beep-page message this process by SGs interface to described terminal called when the network formats of the communication network at the current place of terminal called is E-UTRAN, the time that terminal sends position replacing message will be slightly later to a MSC by SGs interface to described terminal called transmission beep-page message.
When the network formats of the communication network at the current place of terminal called is GERAN, send in the process of beep-page message by A interface to described terminal called, and when the network formats of the communication network at the current place of terminal called is UTRAN, send in the process of beep-page message by Iu interface to described terminal called, the time that terminal sends position replacing message will send beep-page message by A/Iu interface to described terminal called in a MSC a little earlier.
Described 2nd MSC changes according to the position that the described terminal called received sends the address information that the described terminal called carried in message is registered in the first moving exchanging center MSC in Visited Location Registor HLR, location change message is sent to a described MSC, wherein, the address information of the identification information of terminal called and described 2nd MSC belonging to described terminal called is carried in described location change message.
Wherein, described location change message is sent by MAP SendIdentification message, and wherein, the address information of described 2nd MSC belonging to the described terminal called carried in described location change message is carried by following at least mode:
Carried by the GT field of MAP SendIdentification message SCCP layer CallingPartyAddress;
Or, carried by MSC_Number, VLR_Number field of MAP SendIdentification message MAP layer;
Or, carried by MSC_Number, VLR_Number field of MAP CancelLocation message MAP layer.
Step 102: described 2nd MSC sends location update message to Visited Location Registor HLR.
Wherein, described location update message is used to indicate the address information that HLR upgrades the registration of described terminal called, carries the address information of the identification information of terminal called and described 2nd MSC belonging to described terminal called in described location update message.
In a step 102, after described 2nd MSC have sent location update message to HLR, described HLR is according to the address information of described 2nd MSC carried in the described location update message received belonging to described terminal called, and the address information of the first moving exchanging center MSC of the described terminal called registration stored this locality changes to the address information of described 2nd MSC.
Alternatively, described HLR sends to a described MSC and cancels address message.
It should be noted that, it can be before change address information that described HLR sends to a described MSC time cancelling address message, can also be and the time synchronized changing address information, also can determine according to actual needs, not limit here.
Step 103: a described MSC receives the cancellation address message that Visited Location Registor HLR sends.
Wherein, carry the address information that the identification information of terminal called and described terminal called are registered in the described MSC in described HLR in described cancellation address message, and described cancellation address message be described HLR receive that described 2nd MSC sends carry the location update message of the identification information of terminal called after determine.
Alternatively, in step 103, a described MSC, according to carrying the address information that described terminal called is registered in the MSC of described first in described HLR in described cancellation address message, stops the beep-page message that the MSC of response belonging to calling terminal sends.
Like this, the old MSC further illustrating terminal called registration, when receiving cancellation address message, stops the beep-page message that belonging to response calling terminal, MSC sends, for the route of subsequent pages message lays the foundation, and the Internet resources of the old MSC simultaneously saved.
Step 104: the address information of described two MSC of a described MSC belonging to the described terminal called carried in the described location change message received, routes to described 2nd MSC by the beep-page message carrying the identification information of described terminal called that the MSC belonging to the described calling terminal received sends.
At step 104, first, after a described MSC receives the cancellation address message of Visited Location Registor HLR transmission, the address information of described 2nd MSC belonging to the described terminal called carried in the described location change message received, triggers to described 2nd MSC transmit path route messages.
It should be noted that, trigger to described 2nd MSC transmit path route messages can be MAP PRN message.
Wherein, the SSN of described MAP PRN message SCCP layer can be: when not disposing MTRF, from HLR to VLR; When disposing MTRF, from VLR to VLR.
In order to avoid the location updating of terminal called at HLR not yet terminates, one MSC controls a MSC after receiving HLR and sending the setting-up time threshold value cancelled after address message by optimum configurations, the address information of described 2nd MSC belonging to the described terminal called carried in the described location change message received, to described 2nd MSC transmit path route messages.
Wherein, described setting-up time threshold value can be determined according to the average delay of existing network location updating, can also determine, do not limit here according to other modes.
It should be noted that, the scheme of the embodiment of the present invention can be applied in paging way, can also be applied in pre-paging mode, if paging way, also needs to perform " secondly " this step.
Secondly, a described MSC receives the path route response message (i.e. MSRN message) that described 2nd MSC returns, the calling terminal that continues is called out, and the beep-page message carrying the identification information of described terminal called that the MSC belonging to the calling terminal received sends is routed to described 2nd MSC.
That is, if pre-paging mode, at step 104, the address information of described two MSC of a described MSC belonging to the described terminal called carried in the described location change message received, trigger to described 2nd MSC transmit path route messages.
Alternatively, described in the embodiment of the present invention one, a MSC at least belongs to following one:
Support the enhancement mode MSC across MSC calling;
Or, support the enhancement mode SGs MSC called out across MSC CSFB;
Or that supports CSFB calling acts on behalf of MSC.
The scheme of the embodiment of the present invention one is mainly used in the enhancement mode MSC of support across MSC calling when performing paging and pre-paging.
By the scheme of the embodiment of the present invention one, first moving exchanging center MSC receives the location change message of the address information of the identification information carrying terminal called of the second moving exchanging center MSC transmission and described 2nd MSC belonging to described terminal called, and receive the identification information carrying terminal called that Visited Location Registor HLR sends and described terminal called is registered in the cancellation address message of the address information of the described MSC in described HLR, wherein, described cancellation address message be described HLR receive that described 2nd MSC sends carry the location update message of the identification information of terminal called after determine, the address information of described 2nd MSC belonging to the described terminal called carried in the described location change message received, the beep-page message carrying the identification information of described terminal called that MSC belonging to the calling terminal received sends is routed to described 2nd MSC, like this, the old MSC of terminal called registration is according to the location change message receiving the new MSC transmission that terminal called is registered, can determine that the position of the MSC of terminal called registration in paging changes in time, and according to the cancellation address message that the Visited Location Registor received sends, stop the page response to calling terminal, and the beep-page message of calling terminal is routed to the new MSC of terminal called registration, the success rate of paging when the position that effectively improve the MSC of in paging terminal called registration changes.
