Definitions
- the present invention relates to mobile telecommunication switching networks. More specifically, the present invention relates to the interrogation of mobile stations that are statically employed (i.e., immobile), such as mobile stations employed in telemetry applications, and how a mobile telecommunications switching network can take advantage of this immobility to conserve the limited supply of subscriber numbers and to reduce the ever increasing workload on network components such as the home location register (HLR).
- HLR home location register
- Mobile telecommunications networks such as the Personal Digital
- SMS Short message service
- USSD unstructured supplementary service data
- SMS it is characteristic for a host computer to contact one or more telemetry sites over a mobile link, wherein each telemetry site is supported by mobile station.
- the host computer uses short message packets to interrogate each of the one or more telemetry sites.
- the interrogation generally involves a request that each of the sites transmit certain information back to the host computer.
- a utility company such as an electric power company
- the billing computer transmits to the one or more electric meters a short message requesting that each meter transmit their current meter reading back to the billing computer.
- the request includes a unique subscriber number for each meter so that the short message containing the request is properly delivered by the telecommunications switching network.
- the host computer upon receiving the requested information, can then automatically bill its customers.
- each subscriber is assigned a unique numerical identity.
- the unique numerical identity is called the mobile subscriber number (MSN).
- MSN mobile subscriber number
- MSISDN mobile subscriber ISDN
- MSNs and the MSISDNs is to provide each subscriber with a unique address within the PDC and GSM networks respectively.
- the MSNs and the MSISDNs are part of the E.164 international number plan.
- MSN and MSISDN are frequently referred to as subscriber numbers, for the purpose of simplicity.
- the radio interface between each subscriber and the network is assigned an international mobile subscriber identity (IMSI), in accordance with the E.212 numbering plan.
- IMSI international mobile subscriber identity
- the IMSI is also used for distinguishing between mobile stations operating within a given network.
- a MSN or a MSISDN associated with a called party uses the subscriber number to access a subscriber record corresponding to the called party in the network HLR.
- the subscriber record contains, among other things, the information and procedures necessary for routing calls, short messages, and other services to the mobile switching center (MSC) service area in which the called party is located, and eventually to the mobile station corresponding to the called party.
- This information may include, for example, a mobile switching center identification number (MSC-ID) or a routing number, and an IMSI.
- the MSC-ID or routing number is used for routing the call or message to the appropriate MSC which controls the MSC service area in which the called party is located.
- the IMSI is then used to send the call or message from the MSC to the mobile station.
- every subscriber has a unique subscriber number. This is true whether the subscriber subscribes to a cellular voice service or a non-voice service, such as telemetry.
- a telecommunications switching network can limit the number of subscriber numbers assigned, thereby preventing the exhaustion of the E.164 numbering plan, and to reduce the workload on network components, particularly the HLR, to prevent network performance degradation.
- the present invention takes advantage of the fact that in some mobile telecommunications network applications, for example, in most telemetry applications, the mobile stations are not truly mobile. In other words, the location of mobile stations employed for such purposes does not change. Since the location of these mobile stations is already known, the present invention does not require that the calling party (e.g., a host computer) specify a subscriber number to locate such mobile stations. Accordingly, there is no need to assign unique subscriber numbers to these mobile stations. Therefore, the present invention reduces the number of required subscriber numbers by eliminating the need to assign such numbers to mobile stations employed for static applications. Moreover, the present invention reduces the traffic into and out of the network HLR, as there is no longer any need to access the HLR database to obtain location information. Accordingly, it is an objective of the present invention to reduce the number of subscriber numbers for mobile stations operating within a mobile telecommunications network.
- a method and/or an apparatus for routing a message to a called party in a telecommunications network involves generating a message, in a node that is external to the telecommunications network, for the called party.
- the message includes a subscriber identity code corresponding to the called party .
- the method and/or apparatus also involves transmitting the message from the external node to a network switching center associated with a service area, in which the called party is located, in accordance with an area identification code; and forwarding the message from the switching center to the called party as a function of the subscriber identity code, wherein the called party is statically located in the service area.
- a method and/or an apparatus for controlling the routing of a message in a mobile telecommunications network involves generating a message, in a node that is external to the mobile telecommunications network, to a mobile station statically located in an area of the mobile telecommunications network; appending a mobile station identification code to the message, wherein the mobile station identification code uniquely identifies the mobile station; and translating the mobile station identification code into an area identification code and an international mobile subscriber identity code.
- the method and/or apparatus forwards the message to the mobile telecommunications network.
- the message is then routed to a switching center associated with the network area in which the mobile station is located, in accordance with the area identification code, and sent from the switching center to the mobile station using the international mobile subscriber identity code.
- FIG. 1 is diagram depicting a host computer placing a short message to a mobile station in the PDC system, in accordance with the prior art
- FIG. 2 is a diagram depicting a host computer transmitting a short message to a mobile station in the GSM system, in accordance with the prior art
- FIG. 3 is a diagram of a host computer transmitting a short message to a mobile station in the PDC system, in accordance with the present invention.
- FIG. 4 is a diagram of a host computer transmitting a short message to a mobile station in the GSM system, in accordance with the present invention.
- FIG. 5 is a diagram of an external node transmitting information to a mobile station using USSD.
- FIG. 1 illustrates how a host computer 105 interrogates a mobile station 110 in the PDC system, in accordance with the present state of the art.
- the host computer 105 submits (1) a request for a message to be delivered to one or more mobile stations (e.g., mobile station 110).
- the message request is submitted to a short message service center (SMS-C) 115.
- SMS-C 115 is a node external to the switching network.
- the function of the SMS-C 115 is to take the host computer's request and construct one or more appropriate messages in accordance with the short message service protocol. In order to ensure that each message reaches the intended mobile station, each message has appended to it a MSN.
- the SMS-C 115 transmits (2) the message, along with the MSN, to an inter- working/gateway mobile switching center (IW/G-MSC) 120.
- the IW/G-MSC 120 then forwards (3) the MSN to the home location register (HLR) 125.
- HLR home location register
- the HLR 125 is essentially a large database that contains a subscriber record for each subscriber in the network.
- the subscriber record includes, among other things, information identifying which of the many service areas the subscriber is currently located in, as one skilled in the art will readily appreciate. Accordingly, the HLR 125 forwards to the IW/G-MSC 120, what is called a pursuit routing number (PRN) and an IMSI.
- PRN pursuit routing number
- IMSI IMSI
- PRN is essentially an identification number or address for the mobile switching center (MSC), or visiting mobile switching center (VMSC) 130, controlling the service area in which the mobile station 110 is located.
- MSC mobile switching center
- VMSC visiting mobile switching center
- the IW/G-MSC 120 packages the IMSI into an end-to-end information field of a message packet, as is well-known in the art.
- the IW/G-MSC 120 then forwards (4) the message packet to the appropriate VMSC 130, in accordance with the PRN, using an ISDN user part (ISUP) signalling protocol.
- the VMSC 130 then unpacks the message packet, pages the mobile station 110 using the IMSI, and delivers the short message containing the host computer's request to the mobile station 110.
- FIG. 2 illustrates how a host computer 205 similarly interrogates a mobile station 210 in the GSM system using a short message service protocol, in accordance with the present state of the art. First, the host computer 205 generates a short message request.
- SC short message service center
- MSISDN MSISDN that corresponds to the intended mobile station 210.
- the host computer 205 transmits (1) the short message request to the SC-A 215 over an SME interface (e.g., a GSM 03.49 interface), as is well understood by those skilled in the art.
- the SC-A 215 then forwards (2) the short message to the GSM network.
- the SC-A 215 transmits the short message, for example, in accordance with a well- known SMS mobile application protocol 03.49 (e.g., SMS-MAP).
- SMS-MAP short message service, gateway mobile switching center
- the SMS-GMSC 220 uses the SMS-MAP to transmit (3) a send routing information for short message (SRIFSM) instruction to the HLR 225.
- the SRIFSM instruction also contains the MSISDN corresponding to the intended mobile station 210.
- the HLR 225 uses the MSISDN to access the subscriber record corresponding to mobile station 210.
- the subscriber record contains, among other things, information relating to the location of the mobile station 210.
- the HLR 225 sends (4) an MSC-ID code and an IMSI to the SMS-GMSC 220, wherein the MSC-ID code is the network address for the VMSC 230 controlling the service area in which the mobile station 210 is located.
- the SMS-MSC 220 sends (5) the short message to the VMSC 230, which forwards the message to the mobile station 210 using the IMSI.
- the host computer 205 may alternatively employ a USSD signalling protocol to communicate with a desired mobile station, as described in co- pending U.S. Patent Application No. 08/303,027.
- the host computer 205 typically interfaces directly with the network HLR 225 or with the VMSC 230.
- the request generated by the host computer 205 contains or includes the MSISDN corresponding to the intended mobile station 210.
- the MSISDN is then translated into a VMSC-ID and/or an IMSI.
- FIG. 3 illustrates how a host computer 305, in accordance with the present invention, interrogates one or more mobile stations in the PDC system, wherein the mobile stations are employed in a static application such as a telemetry application, or a remote programming application.
- a static application such as a telemetry application, or a remote programming application.
- the mobile station may in fact be restricted in mobility with respect to a particular area or region within the network such as a mobile station service area and/or a paging area.
- the host computer 305 submits (1) a request to transmit a message, using a SMS, to one or more mobile stations such as the mobile station 310 and/or the mobile station 315.
- the mobile stations 310 and 315 are identified in the message request by a unique, though preferably descriptive alpha-numeric address, rather than an MSN.
- the host computer 305 is a billing computer for a utility company, such as an electric power company, and the mobile stations 310 and 315 are electric company meters, the host computer 305 might employ descriptive alphanumeric addresses such as METER00310 and METER00315 to uniquely identify the mobile stations 310 and 315.
- any unique sequence such as a unique binary sequence, or a unique sequence of recognizable characters and/or symbols may be used to compose a mobile station address.
- the SMS-C 320 receives the message request, and with the aid of a database 325 or a lookup table (not shown), the SMS-C 320 translates the one or more descriptive mobile station alpha-numeric addresses.
- the SMS-C 320 and the database 325 translate each mobile station address into a PRN and an IMSI, wherein the PRN is a network address for the VMSC controlling the service area in which the intended mobile station is located.
- each mobile station has a unique combination of PRN and IMSI .
- each mobile station in the network has a unique IMSI.
- a service area under the control of a single VMSC might include several paging areas.
- each paging area is assigned a unique PRN, so that two mobile stations located in different paging areas (i.e., different paging areas associated with one MSC/VMSC or different paging areas associated with different MSCs/VMSCs) could share the same IMSI, thereby conserving the number of available IMSI codes, as well as MSNs.
- the SMS-C 320 and the database 325 may translate the descriptive address of a mobile station into a pursuit routing address, an IMSI, and an MSN.
- the MSN by itself, is not relied upon to uniquely identify the intended mobile station.
- this information is more conveniently stored in the database 325 associated with the SMS-C 320. Therefore, aside from conserving the number of MSNs and, if desired, the number IMSIs assigned to the various subscribers and mobile stations, the present invention also reduces the workload on the network HLR, thereby increasing the efficiency of the network and decreasing message delivery latency rates.
- the SMS-C 320 submits (2) a short message packet using the ISUP signalling protocol to the switching network through an IW/G-MSC 330.
- the IW/G-MSC 330 routes (3) the short message packet to the appropriate VMSC, for example, VMSC 335, in accordance with the PRN.
- the VMSC 335 locates the intended mobile station within its service area utilizing the IMSI, for example mobile station 315.
- the VMSC 335 then sends (4) the message packet to the mobile station 315 through a base station 345.
- the mobile station 315 then unpacks the message packet and extracts the short message sent by the host computer 305.
- the host computer 305 contains the database or lookup table to translate a descriptive mobile station alpha-numeric address into a PRN and an IMSI.
- the host computer 305 then submits (1) the message, along with the PRN and the IMSI, to the SMS 320.
- the SMS 320 primarily handles the messaging protocols that are required for interfacing with the mobile network.
- the advantage of this embodiment is that the task of translating the descriptive mobile station alpha-numeric address into a PRN and an IMSI is performed in a node that is less likely to be affected by a non-real time task.
- maintaining the database or lookup table in the host computer 305 provides added security and helps to preserve customer confidentiality
- FIG. 4 illustrates how, in the GSM system, a host computer 405 may interrogate a mobile station, for example mobile station 410, using a SMS as a message bearer, in accordance with the present invention, wherein the mobile station 410 is employed in a static application such as a telemetry application or a remote programming application.
- the host computer 405 submits (1) a mobile terminated short message (MT-SM) to a short message SC 415.
- the MT- SM includes an identification code other than the MSISDN for the mobile station 410.
- the identification code may be descriptive in nature, and preferably alpha-numeric, although any unique sequence, such as a binary sequence or a sequence of recognizable characters and/or symbols may be utilized. Then, in a manner similar to the SMS-C 320 in FIG. 3, the SC 415 translates the identification code into an IMSI corresponding to the mobile station 410 and a VMSC-
- the SC 415 transmits (2) the MT-SM into the switching network via a gateway MSC (GMSC) 420.
- the GMSC 420 then routes (3) the MT-SM to the VMSC 425 controlling the MSC service area in which the mobile station 410 is located.
- the VMSC 425 then transmits (4) the MT-SM to the mobile station 410 through the appropriate base station controller 430 and the base station transmitter 435.
- a SRIFSM instruction need not be sent to the HLR to locate the mobile station 410.
- the workload on the network HLR is again reduced.
- the unique combination of a VMSC-ID and IMSI is used to identify the MSC service area and the mobile station 410, respectively, not an MSISDN. Therefore, the utilization of an MSISDN can be avoided, thereby conserving the limited number of available MSISDNs.
- the same MSISDN is assigned to each and every mobile station being employed for a particular static application, for use by various network services and applications, wherein each mobile station is still identified by a unique combination of VMSC-ID and IMSI.
- each paging area within a single MSC service area may be identified by a unique MSC-ID number.
- two or more mobile station may share the same IMSI, as long as they are located in different paging areas.
- two or more mobile stations may share the same IMSI if they are located in different MSC service areas.
- This aspect of the present invention reduces the number of required IMSIs, as well as the required number of MSISDNs.
- the mobile station 410 can also initiate a message, for example, in response to a message sent by the host computer 405.
- the mobile station 410 inserts its MSISDN into the mobile originated short message (MO-SM) as an originator address.
- MO-SM mobile originated short message
- each mobile station being employed for the same application can be assigned the same MSISDN.
- the host computer 405 would then distinguish MO-SMs by the IMSI and or the unique combination of VMSC-ID and IMSI.
- the host computer 405 translates the identification code into a VMSC-ID and an IMSI.
- the host computer 405 then submits (1) the MT-SM to the SC 415, wherein the MT-SM already includes the VMSC-ID and the IMSI.
- the SC 415 still handles the messaging protocols required for interfacing with the mobile network.
- the advantage of this embodiment is that the task of translating the identification code into a VMSC-ID and an IMSI is performed by a node (i.e., the host computer 405) that is less likely to be affected by a non-real time task.
- maintaining the database or lookup table in the host computer provides added security and helps to preserve customer confidentiality.
- FIG. 5 illustrates yet another alternative embodiment of the present invention.
- the external node e.g., a host computer
- the external node generates a message, or a text string, which already includes the VMSC-ID and the IMSI needed to uniquely identify the mobile station 510.
- USSD typically interfaces directly with a network HLR 515 or a VMSC 520 which controls the service area in which the mobile station 510 is located.
- the external node might interface with the HLR 515, there is no need to access the subscriber record in the HLR 515 to obtain the information needed to send the message to the mobile station 510, because the external node 505 already provides the VMSC-ID and the IMSI.
- the external node 505 may interface with the network through a gateway MSC 525. Accordingly, FIG. 5 depicts the gateway MSC 525 as a dashed line.
- the host computer may be part of the network. In accordance with this alternative, the host computer would be able to transmit a message directly without having to interface with a GMSC or a HLR.
- SMS or USSD is used as a message bearer
- the number of MSISDNs assigned to mobile stations employed for static applications can be reduced and/or avoided all together by relying on the IMSI or unique combination of VMSC-ID and IMSI to identify each mobile station.
- the various embodiments of the present invention provide a number of advantages.
- Second, the number of IMSIs allocated to mobile stations can be reduced by ensuring that no two mobile stations sharing the same IMSI are located in the same paging area.
