Therefore, by the present invention, no longer need operator to manufacture extraly IP network and carry out transmission of location information, but can utilize the existing network architecture to provide the function of sharing position information for client, thereby saved cost.
Various aspects of the present invention are by the explanation of the specific embodiment by hereinafter and more clear.
Accompanying drawing explanation
By reading the detailed description that non-limiting example is done of doing with reference to the following drawings, other features, objects and advantages of the present invention will become more apparent:
Fig. 1 shows according to an embodiment of the invention for the method flow diagram in PSTN network transmission of location information.
In the drawings, run through different diagrams, same or similar Reference numeral represents identical or corresponding parts or feature.
Embodiment
Fig. 1 shows according to an embodiment of the invention for the method flow diagram in PSTN network transmission of location information.
As shown in Figure 1, user terminal 1 is connected with gateway A by IP network, and gateway A is connected with gateway B by PSTN network, and gateway B transfers to be connected with user terminal 2 by IP network.Although what it may be noted that only shows two gateway A and B at this, but those skilled in the art is to be understood that, gateway A represents that user terminal 1 is to first gateway of signal post's use of user terminal 2 directions, and gateway B represents that user terminal 1 is to last gateway of signal post's use of user terminal 2 directions.Between these two gateway A and B, can also there is the gateway (for example, according to the length of the distance of telephone communication, for example, when carrying out toll telephone, needing more gateways to communicate) of any amount.Certainly, in the situation that distance is shorter, gateway A and gateway B also can become one, and only have a gateway, and it is connected with user terminal 2 with user terminal 1 respectively.
With reference to Fig. 1, first, in step S11, user terminal 1 and user terminal 2 obtain respectively the positional information of self.This positional information can be obtained by the GPS module on user terminal 1 and user terminal 2.For example, user terminal 1 and user terminal 2 all can obtain its current positional information from satellite respectively.
In step S12, user terminal 1 is initiated a phone.In this process, it can, when initiating phone, select this option of sharing position information.Thus, user terminal 1 will send SIP call setup message (SIP INVITE Message) to gateway A by IP network, and this message comprises the positional information of obtaining in step S11 of user terminal 1.
In step S13, gateway A receives the SIP INVITE Message from user terminal 1, and is mapped to the initial address message (ISUP IAM) of ISUP, and wherein the UUI parameter in IAM comprises the positional information of user terminal 1.
In step S 14, gateway A is sent to gateway B by ISUP IAM by PSTN network.In this embodiment, gateway B is the gateway being connected with user terminal 2, so it is without this ISUP IAM being transferred to again to other gateway.
In step S15, gateway B is mapped to the ISUP IAM receiving the SIP INVITE Message of the positional information that comprises user terminal 1.
In step S 16, gateway B is sent to user terminal 2 by this SIP INVITE Message by IP network then.
In step S17, user terminal 2 has received SIP INVITE Message, and has therefrom obtained the positional information of user terminal 1.This positional information can be translated and be presented on the display screen of user terminal 2 by the position translation software of user terminal 2.User terminal 2 can determine whether reply based on this positional information.If replied, user terminal 2 will send SIP180 message (SIP 180Message) by IP network to gateway B in response to this SIP INVITE Message, and this message has comprised the positional information of user terminal 2.This positional information is obtained in step S11.
In step S18, gateway B receives the SIP180 message from user terminal 2, and is mapped to the Address Complete Message (ISUP ACM) of ISUP, and wherein the UUI parameter in ACM comprises the positional information of the second user terminal.
In step S19, gateway B is sent to gateway A by ISUP ACM by PSTN network.In this embodiment, gateway A is the gateway being connected with user terminal 1, so it is without this ISUP ACM being transferred to again to other gateway.
In step S20, gateway A is mapped to the ISUP ACM receiving SIP 180 Message of the positional information that comprises user terminal 2.
In step S21, gateway A is sent to user terminal 1 by this SIP180Message by IP network then.Thus, user terminal 1 also obtains the positional information of user terminal 2, this positional information can be translated and be presented on the display screen of user terminal 1 by the position translation software of user terminal 1, thereby user terminal 1 can be checked the positional information of user terminal 2 on display screen.
Then, as shown in Figure 1, user terminal 2 sends 2000K message by IP network to gateway 2, and it is mapped to ANM by gateway B and then by PSTN network, is transferred to gateway A.Then, gateway A is mapped to ANM again 2000K message and to user terminal 1, sends 2000K by IP network.So far, user terminal 1 is set up with user terminal 2 and has been started call.
After setting up call, if the position of user terminal 2 changes, there is variation in the positional information that is user terminal 2, in step S22, user terminal 2 will send the Session Initiation Protocol message (SIP INFO Message) of the new positional information that comprises user terminal 2 to gateway B by IP network so.
In step S23, gateway B is mapped to the SIP INFO Message receiving the call progress message (ISUP CPG) of ISUP, and wherein the UUI parameter in ISUP CPG comprises the new positional information of user terminal 2.
In step S24, gateway B is sent to gateway A by ISUP CPG by PSTN network.
In step S25, gateway A is mapped to the ISUP CPG receiving the SIP INFO Message of the new positional information that comprises user terminal 2.
In step S26, gateway A is sent to user terminal 1 by this SIP INFO Message by IP network then.Thus, user terminal 1 obtains the new positional information of user terminal 2.Therefore, when the positional information of user terminal 2 changes, user terminal 1 can obtain the up-to-date positional information of user terminal 2 in real time, and vice versa.That is,, when the positional information of user terminal 1 changes, also can utilize the UUI parameter in ISUP CPG to come by PSTN network the new position informing user terminal 2 of user terminal 1.
It should be noted that, above-described embodiment is only exemplary, but not limitation of the present invention.Within any technical scheme that does not deviate from spirit of the present invention all should fall into protection scope of the present invention, this comprises the different technologies feature that use occurs in different embodiment, and installation method can combine, to obtain beneficial effect.In addition, any Reference numeral in claim should be considered as limiting related claim; " comprise " that a word do not get rid of device unlisted in other claims or specification or step.
