[0045] 7. Possible certification process;
When a terminal in dual-network registration mode shuts down in a single-network coverage area, since the detach process is only initiated on the single-network, the terminal-related information saved on the heterogeneous The heterogeneous network element information cannot be deleted in time. At this time, the terminal is already in an unreachable state. When there is a call or a short message that needs to be routed to the terminal, the heterogeneous network element and the HSS cannot correctly and timely transfer the unreachable information of the terminal. to respond
In addition, if a terminal in dual-network registration mode shuts down in the dual-network coverage area, it needs to initiate a similar detach process to both networks, which will cause waste of signaling

Embodiment 1

[0097] This embodiment describes the process of a dual-mode terminal (hereinafter referred to as the terminal) first attaching to the 2G / 3G system and then moving to the SAE / LTE system, and the process of first attaching to the SAE / LTE system and then moving to the 2G / 3G system. The HSS realizes the parallel registration of the terminal on the dual networks according to the instruction to deregister the heterogeneous network entity (Digister Inhomogenous NetworkEntity).

[0098] see Figure 5 , which is a schematic flow diagram of the dual-mode terminal first attaching to the 2G / 3G system and then moving to the SAE / LTE system according to the embodiment of the present invention. The specific steps include:

[0099] 1. The terminal initiates an attach request to the SGSN, and carries the IMSI in the Attach Request message;

[0100] 2a-2b. If the ID brought by the terminal is not an IMSI, the new SGSN requests the IMSI from the old SGSN;

[0101] 3a-3b. If the new SGSN fails t...

Embodiment 2

[0137] This embodiment describes the process of the terminal first attaching to the 2G / 3G system and then moving to the SAE / LTE system, and the process of first attaching to the SAE / LTE system and then moving to the 2G / 3G system. , to realize the parallel registration of the terminal on the dual network.

[0138] In this embodiment, the dual-mode terminal first attaches to the 2G / 3G system and then moves to the SAE / LTE system. Figure 5 The flow shown is similar, except that the indication information carried in the location update message is an update type identifier. Specific process and Figure 5 Similar as shown, the different steps are:

[0139] In steps 5a-5h, the new SGSN sends a registration message to the HSS, carries the update type identifier in the registration message, and sets the update type as attach; after receiving the message, the HSS triggers the old SGSN according to the indication that the update type is attach and old MME delete the information of the...

Embodiment 3

[0150] This embodiment describes the process of the terminal first attaching to the 2G / 3G system and then moving to the SAE / LTE system, and the process of first attaching to the SAE / LTE system and then moving to the 2G / 3G system, the HSS registers the network element address as needed , to realize the parallel registration of the terminal on the dual network.

[0151] In this embodiment, the dual-mode terminal first attaches to the 2G / 3G system and then moves to the SAE / LTE system. Figure 5 The flow shown is similar, except that the indication information carried in the location update message is the address of the network element that needs to be registered. Specific process and Figure 5 The flow shown is similar, the different steps are:

[0152] In steps 5a-5h, the new SGSN sends a registration message to the HSS, carries the address of the network element to be registered in the registration message, and sets this address as the address of the new SGSN; after the HSS r...

Abstract

The present invention discloses a multi-mode terminal register method in heterogeneous network and a device using the same. The method includes steps as follows: first internet element sends register message to HSS after receiving multi-mode terminal request; an indicator message is carried in register message for indicating HSS informing heterogeneous element to delete message relative to said multi-mode terminal, or indicating HSS keeping heterogeneous element message relative to said multi-mode terminal; HSS device processes corresponding register according with said indicator message. The invention also discloses a multi-mode terminal register method in heterogeneous network and a device using the same. When processing register by using the method, HSS can be various processed appointing to various register request, and unnecessary message is deleted in time at the same time realizing double-internet register. When processing register by using the method, terminal relative message of heterogeneous internet and heterogeneous element message can be deleted in time, and signaling cost can be saved.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a method and device for registering a multi-mode terminal in a heterogeneous network. Background technique [0002] After 3GPP (Third Generation Mobile Communications Standardization Organization) introduces SAE / LTE (System Architecture Evolution / Long Term Evolution) technology, the original 3GPP communication system will coexist with the new technology SAE / LTE for a period of time, and it is under construction In the early stage of the network and for a long period of time, it will be in the state of wide coverage of the original 3GPP communication system and hot spot coverage of the SAE / LTE system. In order to use network resources, in the original 3GPP system and SAE / LTE system, the terminal needs to initiate a registration process to the network, and the network element HSS (Home Subscriber Server, Home Subscriber Server) needs to record the terminal's subscripti...
