Fig. 5 is a schematic diagram of an embodiment of a system for implementing information interworking in an SCEF scenario according to the present invention. As illustrated in fig. 5, the system may include a SCEF device 501, a first apparatus 502, and a second apparatus 503. Wherein:
the SCEF device 501 is the device according to any of the embodiments in fig. 4.
The first device 502 is configured to send the first information to the SCEF means 501.
The second device 503 is configured to send the second information sent by the SCEF apparatus 501 to the receiving side.
The type of the first information is one of NB-IoT non-IP data packets and short messages, and the type of the second information is the other one of NB-IoT non-IP data packets and short messages.
In the first case, the type of the first information is a short message, and the first device 502 is a short message gateway to which the receiving party belongs; the type of the second information is NB-IoT non-IP packet, and the second device 503 is an MME (Mobility Management Entity) on the receiver side.
In the second case, the type of the first information is NB-IoT non-IP packet, and the first device 502 is the MME of the sender side; the type of the second information is a short message, and the second device 503 is a short message gateway to which the sending party belongs.
The MME and the SCEF can interact through an interworking function module IWK-SCEF.
The following describes the present invention by taking an example of short message interaction between a user terminal and a service provider SP.
The SP sends a short message to the user terminal as shown in fig. 6.
1. After editing the short message, the SP 61 submits the short message to the SP home short message gateway SMGW 62, and the destination address of the message is the user terminal 67.
2. The SP home SMGW 62 initiates authentication to the SP 61, and after the SP authentication is passed, the SP home SMGW 62 forwards the short message to the user home SMGW 63 according to the H code.
3. The SMGW 63 sends the short message to the subscriber service SCEF 64 according to the subscriber number field.
4. The SCEF 64 extracts the short message content in the SMPP message, queries the IMSI of the user according to the MSISDN number of the user, encapsulates the short message content in a non-IP data packet, and sends the non-IP data packet to the visited MME 66 through the IWK-SCEF module 65 by using the T6a connection established during attachment.
5. The MME 66 sends the non-IP packets to the target user terminal 67 through NAS signaling.
(II) the user terminal sends a short message to the SP as shown in FIG. 7.
1. After the user terminal 77 attaches, it sends a non-IP data packet (containing the short message content and the destination SP number) to the user visited MME 76.
2. The MME 76 forwards the message to the local IWK-SCEF function 75.
3. The local IWK-SCEF function 75 addresses the serving SCEF 74 to which the user has signed up.
4. The SCEF 74 extracts the short message content and the destination SP number from the non-IP data packet, looks up the user MSISDN number according to the user IMSI, re-encapsulates it into an SMPP message, and sends it to the user home SMGW 73.
5. The subscriber home SMGW 73 transmits a short message to the SP home SMGW 72 according to the SP number.
6. The SP home SMGW 72 transmits the short message to the target SP 71.
According to the example, the SCEF is arranged between the MME and the SMGW of the current network of the C network, so that the SCEF is equivalent to an SMSC to the SMGW, thereby realizing the conversion of short messages and non-IP data packets and meeting the short message requirement of NB-IoT. In the process, the user realizes the short message receiving and sending with the SP through the MME from the control plane, and the user terminal does not need to support the circuit domain attachment to receive the short message.
Furthermore, in the present invention, the SCEF may be further configured to:
the SCEF implements the conversion of short messages to control plane non-IP packets.
The user signs up for the serving SCEF, and at the time of attachment, a T6a connection is established between the MME to which the user is attached and the serving SCEF (through the IWK-SCEF connection in the roaming scenario). The SCEF needs to add the following functions to realize the docking with the current network short message gateway of the network C:
mapping between the IMSI and the MSISDN number of the subscriber is configured in advance (implemented by a uniform system or batch import), and the conversion between the IMSI and the MSISDN number of the subscriber is implemented.
Convert short message content in SMPP protocol to NB-IOT non-IP packets.
Through the analysis, the network elements of other core networks of the NB-IOT do not need to support the function related to the short message, and the terminal does not need to support the circuit domain to attach and receive the short message.
Meanwhile, service network elements such as a C-network current network short message gateway and the like do not need to be modified, and only the configuration of an NB-IOT user number segment needs to be increased, so that the user attributive SMGW can be addressed to an NB-SMSC.
Therefore, when the method and the device are implemented, the NB-IoT terminal is not required to be attached to and receive the short message in the circuit domain, the implementation is simpler, and the message transmission efficiency is not reduced.
It will be understood by those skilled in the art that all or part of the steps for implementing the above embodiments may be implemented by hardware, or may be implemented by a program instructing relevant hardware, where the program may be stored in a computer-readable storage medium, and the above-mentioned storage medium may be a read-only memory, a magnetic disk or an optical disk, etc.
The description of the present invention has been presented for purposes of illustration and description, and is not intended to be exhaustive or limited to the invention in the form disclosed. Many modifications and variations will be apparent to practitioners skilled in this art. The embodiment was chosen and described in order to best explain the principles of the invention and the practical application, and to enable others of ordinary skill in the art to understand the invention for various embodiments with various modifications as are suited to the particular use contemplated.
