Now, will describe in detail according to the present invention, under various user's service states, the process of the location-based service of carrying out among the MSC.
Fig. 5 a is illustrated in location-based viability, at the flow chart of the processing procedure of MSC treatment S MS.
During location-based service (LBS), when MSC received SMS, MSC utilized visitor location register (VLR) to keep SMS (S610), and the SMDPP results messages is sent to SMS service center (SMC) (S620).For example, the value of SMS_CauseCode that sends to the results messages of SMC is 0x24 (SMS transmits and postponed).At this, MSC normally carries out location-based service (S630).When location-based service finishes (S640), MSC sends to SMC (S650) with the SMS notification message, and receives SMS (S660).Therefore, when location-based service finished, the mode with identical when utilizing the standby mark of SMS to send this message by MSC sent the SMS notification message.
Fig. 5 b is illustrated in location-based viability, handles the flow chart of the processing procedure of handover at SMC.
Call out at MS, and when location-based service was provided, if handover takes place, then MSC only finished location-based service (S720), and keeps call business channel (S730).Then, MSC sends to PDE (S760) with the SMDPP results messages.For example, the value of the SMS_CauseCode of results messages is 0x06 (network interface that is not supported).
On the other hand, call out, and when location-based service was provided, if handover takes place, then MSC only finished location-based service (S740) and discharges Traffic Channel (S750) at MS.After this, MSC sends to PDE (S760) with the SMDPP results messages.For example, the value of the SMS_CauseCode of results messages is 0x06 (network interface that is not supported).
When MSC provided location-based service under call state, after successfully finishing handover, MSC sent to PDE with the SMDPP results messages.For example, the value of the SMS_CauseCode of results messages is 0x06 (network interface that is not supported).
Fig. 5 c is illustrated in the flow chart that MSC handles the processing procedure of the SMDPP message that PDE sends.
When sending the SMDPP request message of location-based service, the length of PDE SMS teleservice identifier parameter is set to " 0 ".The SMS teleservice identifier parameter does not send to MS, because do not have respective field in the CHARi of the data burst message that utilizes wireless transmission field.
Service indicator parameter in SMDPP message is set to CDMA_PDS, and during with treatment S MS carrying data parameters (S810 and S811), MSC extracts location-based service data message (S812).The location-based service data message of extracting is appended to the CHARi field of utilizing the wireless data burst message that sends in forward traffic channel, and it is sent to MS (S813).
Under the state in the user is not present in MSC or VLR, when MSC receives SMDPP request message (S820), if action code (Action Code) be 0x12 (resource allocation AllocateResources) (S830), then MSC carries out location registers again.That is, MSC asks qualification (S840), notification enrollment (S850) and carries out location-based service.In the time of in MS is present in corresponding MSC/VLR, the normal execution of MSC location-based service (S870), and in MS is not present in MSC/VLR the time, the SMS_CauseCode of MSC SMDPP results messages is set to 0x20 (not having page response), and this message is sent to PDE (S861).The operation that the action code parametric representation will be carried out by the appointed function unit, and SMS_CauseCode represents the SMS failure cause.
Under the situation in the user is not present in MSC or VLR, when MSC received the SMDPP request message, if action code is not 0x12 (resource allocation), then MSC sent to PDE (S831) with the SMDPP results messages.At this, the SMS_CauseCode of results messages is set to " Destination no longer at this address (this address no longer is the destination) ".
Fig. 5 d is the flow chart that is illustrated in the processing procedure of MSC processing resource allocation and release.
Now, will illustrate at MSC and carry out resource allocation (S910).Being in the free time during (IDLE) state (S911) at MS, is the SMDPP request message of 0x12 (resource allocation) if MSC receives action code from PDE, and then MSC distributes new business channel (S912), and starts location-based service (S913).Can not the distribution service channel time, the SMS_CauseCode of MSC SMDPP results messages be set to 0x20 (not having page response), and sends this message.On the contrary, when MS was in session status, MSC did not distribute the new business channel, and used the existing business channel to start location-based service (S914).
Now, will illustrate that carrying out resource in MSC discharges (S920).When the Traffic Channel of being distributed only was used to carry out location-based service and do not have calling, MSC discharged the Traffic Channel (S931) that inserts MS, and the SMDPP results messages is sent to PDE (S950).At this, the SMS_BearerData parameter is set to the response message in the MS reception.On the contrary, when there is voice call in MS (S930), MSC keeps this Traffic Channel carrying out voice call, and finishes location-based service conversation (S940).After this, MSC sends to PDE (S950) with the SMDPP results messages.At this, the SMS_BearerData parameter is set to the response message in the MS reception.If location-based service conversation is invalid, then MSC SMS_CauseCode parameter is set to 0x6C (session is invalid), and the SMDPP results messages is sent to PDE.
Now, will the situation of the location-based service conversation of abnormal end in MSC be described.
Begin to carry out location-based service at the MS that is in idle condition, and this MS attempts to send when calling out, if MSC receives release message from MS, then MSC finishes location-based service conversation, and carries out the general calling procedure that sends.At this, MSC SMS_CauseCode parameter is set to 0x6C (session is invalid), and the SMDPP results messages is sent to PDE.
Begin to carry out location-based service at the MS that is in idle condition, and this MS is when attempting receipt of call, MSC finishes location-based service conversation.MSC SMS_CauseCode parameter is set to 0x21 (destination is busy), and SMDPP message is sent to PDE.
When the MS that is in busy condition began to carry out location-based service and terminated call, MSC finished location-based service conversation.MSC SMS_CauseCode parameter is set to 0x6C (session is invalid), and SMDPP message is sent to PDE.
On the other hand, at location-based viability, when MS and Traffic Channel disconnection, MSC finishes location-based service conversation.From MS reception release message the time, MSC SMS_CauseCode parameter is set to 0x6C (session is invalid), and the SMDPP results messages is sent to PDE.MSC not when MS receives Ack (affirmation) message (overtime) in the given time, MSC SMS_CauseCode parameter is set to 0x22 (unconfirmed), and the SMDPP results messages is sent to PDE.
At location-based viability, from MS receiving radio data access request the time, MSC finishes location-based service conversation, and carries out the wireless data access procedure.MSC SMS_CauseCode parameter is set to 0x6C, and the SMDPP results messages is sent to PDE.
In addition, at location-based viability, when MS cut off the power supply, MSC finished location-based service conversation, and the SMDPP results messages is sent to PDE.At this, the SMS_CauseCode parameter that sends is set to 0x6C (session is invalid).On the other hand, at location-based viability, the battery of MS and body portion from the time, MSC finishes the LBS session, and the SMDPP results messages is sent to PDE.At this, when MS received release message, MSC SMS_CauseCode parameter was set to 0x6C (session is invalid) at MSC, and when MSC did not receive Ack message, MSC SMS_CauseCode parameter was set to 0x22 (unconfirmed).
At location-based viability, whenever MSC when PDE receives the SMDPP request message, MSC just starts inactivity timer (inactivity timer).When the inactivity timer was terminated, MSC finished location-based service, and the SMDPP results messages is sent to PDE.At this, when action code was resource allocation, then MSC SMS_CauseCode parameter was set to 0x20 (not having page response).When MSC can not the distribution service channel, MSC SMS_CauseCode parameter was set to 0x42 (other radio interface problems).In addition, not when MS receives Ack message, MSC SMS_CauseCode parameter is set to 0x22 (unconfirmed) at MSC.
As previously mentioned, according to the present invention, according to the service function of the MS of mobile communication subscriber or the position service function of MSC, can optionally provide based on based on the sub-district and based on the service of the position of GPS.Therefore, can in all MS, finish location-based service.In addition,, utilize SMDPP message, can provide based on service, and can during the voice call of MS, realize this service based on the position of GPS by the N07 signal network.
