Problems solved by technology

[0058] With the development and maturity of M2M technology and the diversification of M2M applications, the number of M2M terminals (ie MTC devices) will increase explosively. It is estimated that the number of MTC devices will reach two orders of magnitude of the number of handheld terminals. Due to MSISDN The length has a 16-bit length limit in the international standard, which will lead to insufficient MSISDN resources and cannot allocate an MSISDN for each MTC device, which will cause addressing problems when the MTC device sends business messages (such as short messages)

Embodiment 1

[0117] When the MTC device accesses the visited access network, it sends a location update request message to the HSS of its home network, and the MTC IWF intercepts the message as a signaling transfer node, and obtains the IMSI (private number) of the MTC device carried in the message; When the HSS of the home network returns a location update response message to the MTC device, the MTC IWF intercepts the message and, according to the instructions in the location update response message, registers with the home network (IMS network element) of the MTC device instead of the MTC device. Process such as Figure 6 shown, including:

[0118] Step 601, when the MTC device accesses the visited access network, it sends an attach request message to the network element (MSC, or SGSN, or MME) of the visited access network, and the message carries the IMSI (private number) of the MTC device;

[0119]Step 602, after receiving the attachment request message, the network element of the vis...

Embodiment 2

[0132] The home network of the MTC device supports IMS. The MTC server sends the short message to the MTC IWF through the home network, and the process of forwarding the short message to the MTC device through the MTC IWF is as follows: Figure 7 shown, including:

[0133] Step 701, the MTC server sends a short message in common format to the SC or SMS-GMSC, and the destination address is the PUI of the destination MTC device;

[0134] Step 702, after receiving the short message, the SC or SMS-GMSC forwards the normal format short message to the IP-SM-GW according to the PUI;

[0135] Steps 703-704, IP-SM-GW converts the common format short message into the SIP format short message that can be transmitted in the IMS network (home network), and sends the SIP format short message to the IMS network element (home network); The network element determines the corresponding MTC IWF according to the registration information of the MTC device, and forwards the short message in SIP fo...

Embodiment 3

[0140] The home network of the MTC device supports IMS. The MTC device sends a normal-format short message to the MTC IWF. The MTC IWF converts the normal-format short message into a SIP-format short message, and sends the short message to the MTC server through the home network. Figure 8 shown, including:

[0141] Step 801, the MTC device sends a normal-format short message to the network element of the visited access network, the source address is the IMSI of the MTC device, the destination address is the address of the MTC server, and the short message carries the SC or SMS-IWMSC address;

[0142] Step 802: After receiving the normal format short message, the network element of the visited access network updates the source address from IMSI to P-MSISDN (as described in step 606, when the MTC device is attached, the network element of the visited access network saves the P-MSISDN), and forwarded to MTC IWF. Here, the MTC IWF associated with the network element of the visit...

Abstract

The invention discloses a method for sharing a subscriber number of machine type communication (MTC) equipment. The method comprises the following steps that: an MTC inter-working function (IWF) of a logic function entity is set; when the MTC equipment accesses a visiting place access network, the MTC IWF stores a correspondence relationship between a public number and a private number of the MTC equipment to generate a comparison table of the public number and the private number of the MTC equipment; and the MTC IWF routes the service of the MTC equipment according to the comparison table of the public number and the private number of the MTC equipment. By the invention, the problem of lacking in resources of mobile station international integrated service digital network numbers (MSISDN) during allocation of the MSISDN to the MTC equipment can be solved.

Description

technical field [0001] The present invention relates to machine-to-machine communication (M2M) technology, in particular to a method and system for sharing user numbers of machine-type communication (MTC) equipment. Background technique [0002] In recent years, M2M (Machine to Machine, machine-to-machine communication) services have gradually begun to be applied, such as logistics systems, remote meter reading, smart home and other applications. M2M service providers use existing wireless networks, such as GPRS (General Packet Radio service, General Packet Radio Service) network, EPS (Evolved Packet System, Evolved Packet System) network and other Packet Switching (PS) networks to carry out M2M services. [0003] M2M business is a networked application and service centered on the intelligent interaction of machine terminals. It uses intelligent machine terminals to transmit information through wireless networks, and provides customers with information solutions to meet cust...
