Problems solved by technology

[0015] It can be seen from the above solution that in the prior art, the UE uses the E.164 number format in the CS domain to call the MSC / VLR. When the UE is roaming, the VMSC may use different access numbers depending on the country or region, such as For the fire alarm, it is 119 in China, and it may be 911 in the United States. When the UE roams and attaches to the VMSC, it must use the access number recognized by the local VMSC to access the required services; the access in the VMSC is used for routing analysis The code is pre-configured based on local numbering and routing planning, and cannot be dynamically adjusted in real time. These data are information held by the operator, and the existing solutions for UE handover between the CS domain and the IMS are not based on the location of the UE. The mechanism of updating the UE access code in time, in this way, it is very likely that the VMSC cannot recognize the access code used by the UE, such as the E.164 number or the AS number, because the access code in the UE is inconsistent with the access code in the VMSC. PSI, so that the correct routing for the session cannot be performed, and the UE fails to switch to IMS during the CS call

Embodiment 3

[0153] Embodiment 3: The entity to which the re-allocation logic module and the re-allocation judgment module belong is both the HSS, and the AS has not changed. The UE can also initiate registration to trigger the update of the UE access code. When the HSS learns that the UE has successfully registered, the HSS uses the methods described in steps 304 to 306 to determine that the MSC / VLR to which the UE belongs changes and then reassigns the UE access code, and reassigns the obtained E.164 The number is sent to the UE in steps 307 to 308, and the UE updates the local E.164 number. It should be noted that if the UE is initially registered, that is, there is no location information of the UE before registration in the HSS, then the HSS directly reassigns the UE access code according to the current location information of the UE obtained in steps 304 to 306 . Here, the UE registration process and the HSS knowing that the UE has successfully registered belong to the existing known...

Embodiment 5

[0167] The difference between Embodiment 5 and Embodiment 4 is that in Embodiment 4, the IMS AS carries the reassigned AS PSI in the SIP Notify message and forwards it to the UE; in Embodiment 2, the reassigned AS PSI is carried in the SIP PUBLISH message and forwards to UE.

[0168] Figure 6 is a flow chart of Embodiment 6 of the present invention. In this embodiment, the entity to which the redistribution logic module belongs is IMS AS, the entity to which the redistribution judgment module belongs is STP, and the AS has not changed; assume that different MSC / MSCs are preset in IMSAS. The corresponding relationship between the VLR number and the UE access code, the position of the UE has changed, according to the agreement, after the MSC / VLR receives the routing update request sent by the UE, the method includes the following steps:

[0169] Step 600-Step 603: The CS domain STP intercepts the MAP_UPDATE_LOCATION message and MAP_UPDATE_LOCATION_ack message between the MSC / VLR...

Abstract

This invention discloses one method and device to update user terminal interface codes, which realizes UE interface codes re-layout logic module and comprises the following steps: pre-setting relationship between UE position information and UE interface codes and re-matching logic module to get UE position information; according to UE current position information to re-layout UE interface codes to get UE interface codes to call executive point UE or gems and UE.

Description

technical field [0001] The invention relates to a cross-domain call technology, in particular to a method and a device for updating an access code of a user terminal (UE) when the user terminal (UE) is in a roaming state. Background technique [0002] Starting from the 3rd Generation Partnership Release 5 (3GPP R5), the core network of the Universal Mobile Telecommunications System (UMTS) is divided into three subsystems: Circuit Switching (CS), Packet Switching (PS) and IP Multimedia Subsystem (IMS). ). Among them, the CS domain (Circuit Switched Domain) is used to provide users with circuit-type service connections, including several main entities such as Mobile Switching Center (MSC), GMSC, and Interoperability Function (IWF) modules, MSC (MSC Server / CS-MGW ) is used to complete the switching and signaling control functions of circuit-switched services; GMSC is an MSC that completes the routing addressing function of mobile users in a certain network, and can be set up t...
