Problems solved by technology

[0009] From the above analysis, it can be seen that the time zone information of the UE cannot be obtained from the existing 3GPP specification definition. Such bills have defects in user billing, bill query, settlement reconciliation, etc. If the discount is calculated in the user's local time, the information about the user's communication time point in the statistical information will also be wrong, resulting in a decrease in customer satisfaction and affecting the operator's revenue

Embodiment 1

[0132] This example Figure 7 In the shown network architecture, UE41 reports time zone information, PCSCF42 trusts the reported information of UE41 according to the configuration, time zone 1≠time zone 2, and adopts ANI mode to carry time zone information on the calling side (IMS-A), to implement the IMS charging method, Such as Figure 8 As shown, the method includes the following steps:

[0133] Step 501: UE41 carries the PANI header with added time zone information in the INVITE request sent to PCSCF42;

[0134] Specifically, the UE41 extends the PANI header, adds a time zone information field in the access information part, adds its own time zone information to the time zone information field, and then carries the PANI in the INVITE request sent to the PCSCF42. head.

[0135] Step 502: After receiving the INVITE request, PCSCF42 carries the PANI header with time zone information added in the INVITE request sent to SCSCF43;

[0136] Step 503: After receiving the INVITE...

Embodiment 2

[0151] This example Figure 7 In the shown network architecture, UE41 reports or does not report time zone information, and the access layer network element provides time zone information to PCSCF42, and PCSCF42 does not trust the reported information of UE41 according to the configuration, then implements the IMS charging method during offline charging, Such as Figure 9 As shown, the method includes the following steps:

[0152] Step 601: UE41 carries or does not carry time zone information in the SIP INVITE request sent to PCSCF42, and the access layer network element carries time zone information in the SIP INVITE request sent to PCSCF42;

[0153] In this step, the INVITE request sent by the UE41 or the access layer network element carries time zone information, specifically: the INVITE request sent by the UE41 or the access layer network element carries a PANI header with time zone information added.

[0154] Step 602: PCSCF42 carries the PANI header with added time zon...

Embodiment 3

[0174] This example Image 6 In the network architecture shown, UE41 and the access layer network elements do not provide time zone information, and PCSCF42 determines the time zone information of UE41 according to the location information, then implements the IMS charging method during offline charging, such as Figure 10 As shown, the method includes the following steps:

[0175] Step 701: UE41 sends a SIP INVITE request to PCSCF42;

[0176] Step 702: After receiving the INVITE request, PCSCF42 carries the PANI header with time zone information added in the INVITE request sent to SCSCF43;

[0177] In this step, the PCSCF maps the time zone information of the UE41 in its own configuration table according to the location information of the UE41 provided by the UE41 or the access layer network element, such as: Tracking Area (TA, TrackingArea) or CellID, etc. And the time zone information is added to the PANI header of the INVITE request sent to the SCSCF43; the configuration...

Abstract

The invention discloses a method for supporting multiple time zones by an IP multimedia subsystem (IMS). The method comprises the steps of: carrying time zone information in a session initializing protocol (SIP) message which is sent to control layer network elements except the proxy-call session control function (PCSCF) network element by a proxy-call session control function network element; after receiving the time zone information obtained by the control layer network element which receives the SIP message, carrying the time zone information in the SIP message sent to a business layer network element; and receiving the SIP message sent by the control layer network element and obtaining the time zone information carried by the SIP message by the business layer network element. At the same time, the invention discloses a system for supporting the multiple time zones by the IMS, and a charging method and system. According to the scheme of the invention, the time zone information can be transmitted to each network element in the IMS, and the charging data record carrying the user local time in a call is realized, thereby the charging accuracy is increased.

Description

technical field [0001] The present invention relates to the third generation partnership project (3GPP) technology, in particular to an IP multimedia subsystem (IMS, IPMultimediaSubsystem) method and system for supporting multiple time zones and a charging method and system. Background technique [0002] In the IMS network architecture described by the 3rd Generation Partnership Project (3GPP), a core network may cover users in multiple time zones in a country, such as the case of the United States. Therefore, user equipment (UE, UserEquipment), access layer network elements (AccessNetworkNodes), IMS control layer network elements, and service layer network elements are likely to be distributed in the same or different time zones. The time zone information where the UE is located is of great significance to the operation of the operator from the perspectives of billing, statistics, and quality of service (QoS) control. In the existing 3GPP protocol specification, the time s...
