Problems solved by technology

This method tightly couples the UE's external ID to the UE's internal ID, and loses the flexibility of the application layer to control the UE's external ID, which brings inconvenience
[0027] The mapping relationship between the UE's internal ID and external ID in the related art is stored in the HLR / HSS as the UE's subscription data. When the application layer needs to change the UE's external ID for some purpose, the HLR / HSS must be notified To change the subscription data, this method tightly couples the UE's external ID to the UE's internal ID, and loses the flexibility of the application layer to control the UE's external ID. At present, no effective solution has been proposed

Embodiment 1

[0096] Figure 5 It is a flow chart determined according to Embodiment 1 provided by the present invention. In this example, the UE registers internal and external IDs with the MTC IWF through PCO, and the specific processing flow is as follows.

[0097] Step S502, the UE sends the external ID of the UE to the GGSN / PGW through the PCO message;

[0098] PCO is used to negotiate protocol configuration parameters between UE and GGSN / PGW, for example: UE tells GGSN / PGW the type of IP protocol supported, the version number of GTP protocol, etc., or UE requests PGW to allocate P- CSCF, etc. PCO parameters are usually provided when the UE requests a PDP / PDN connection, and are transparently transmitted to the GGSN / PGW through the SGSN / MME. It is only transparently transmitted during transmission.

[0099] Step S504, after receiving the external ID sent by the UE, the GGSN / PGW notifies the MTC IWF of the UE's internal ID and external ID.

[0100]When the UE establishes an IP beare...

Embodiment approach

[0130] The UE registers the identity of the UE with the MTC IWF through NAS. There may also be multiple implementations, wherein the transmission entities or servers involved in each implementation may be the same or different. Specifically, a preferred implementation includes:

[0131] The UE sends the external identity of the UE to the serving general packet radio service support node SGSN / mobility management entity MME through a NAS message; the SGSN / MME acquires the internal identity of the UE according to the context of the UE; the SGSN / MME sends the UE's The external logo and internal logo are notified to MTC IWF and registered.

[0132] Another preferred embodiment for the UE to register the UE's identity with the MTC IWF through NAS includes: the UE sends the UE's external identity to the SGSN / MME through a NAS message; the SGSN / MME determines the UE's internal identity according to the UE's context; The SGSN / MME sends the UE's external identity and internal identity t...

Embodiment 2

[0136] Figure 8 It is a flowchart determined according to Embodiment 2 of the present invention. In this example, the UE registers internal and external IDs with the MTC IWF through NAS signaling;

[0137] Step S802, the UE sends the external ID of the UE to the SGSN / MME through a non-access stratum (NonAccess Stram, NAS) message;

[0138] NAS message is a message type used for communication between UE and SGSN / MME. The endpoints of NAS message are UE and SGSN / MME. Any other nodes (such as wireless nodes) on the message transmission path will not parse NAS message.

[0139] Step S804, after receiving the external ID sent by the UE, the SGSN / MME notifies the MTC IWF of the mapping relationship of the UE's internal / external ID.

[0140]When the UE accesses the network, the SGSN / MME can learn the internal ID of the UE. For example, the IMSI is provided by the UE during the Attach process (Attach process), and the MSISDN is obtained by the SGSN / MME from the subscription data of ...

Abstract

The invention discloses a mapping method, a device and a system for terminal identifications. The mapping method includes that a machine type communication interworking function (MTC IWF) stores a mapping relation between an internal identification (ID) and an external ID of user equipment (UE); and the MTC IWF completes conversion from the external ID to the internal ID of the UE according to the mapping relation while receiving information sent to the UE. By using the mapping method, the device and the system, the mapping relation of the internal ID and the external ID of the UE can be stored in the MTC IWF rather than in a home location register / home subscriber server (HLR / HSS), when the external ID of the UE is needed to change on the application layer out of certain purposes, the HLR / HSS is not needed to be informed to change signing data, therefore the external ID of the UE is prevented from being closely coupled on the internal ID of the UE, and control flexibility of the application layer on the external ID of the UE is improved.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a terminal identification mapping method, device and system. Background technique [0002] In mobile communications, an application server (Application Server, AS) often needs to communicate with a user terminal (User Equipment, UE). In related technologies, there are two ways of communication between application services and user terminals: user plane communication (referred to as user plane communication for short) through the IP addresses of both parties, and control plane communication (referred to as control plane communication for short) via mobile network control plane nodes. communication). In user plane communication, the application server and the user terminal know each other's IP address, and the IP address is reachable, so they can communicate directly through the IP address. The control plane communication is usually applied in the case where the application ser...
