[0083] Statically configure SGs / Gs related information in the ISR activation judgment network element. According to the capabilities of the network (including whether the EPS network supports CSFB and ISR functions, whether the SGSN supports the Gs interface and ISR functions), configure SGs and Gs related information in the MME and / or SGSN through static configuration. When the MME and / or SGSN are used as ISR activation judgment network elements, it is determined whether to activate the ISR function according to the static configuration information therein.

[0084]Specifically, the following information needs to be configured in the MME: whether the connected SGSN is currently working in the mode supporting the Gs interface; whether the MME is currently working in the mode supporting the SGs interface and whether it supports the ISR function. The following information needs to be configured in the SGSN: whether the connected MME works in the mode supporting the SGs interface...

[0092] In this embodiment, the ISR activation judging network element dynamically acquires SGs / Gs related information during the ISR activation process, and the SGs / Gs related information is information on whether the context request responder network element is working in a mode supporting the Gs / SGs interface.

[0093] The MME / SGSN does not need to statically configure whether the SGSN / MME connected to itself is working in the mode of supporting the Gs / SGs interface, but the ISR activates the peer SGSN / MME to carry whether it is working in the mode of supporting the Gs / SGs interface in the context response message information. When MME / SGSN updates TAU / RAU, it judges whether it wants to establish an SGs / Gs association relationship, and whether the ISR activates the other party to support the Gs / SGs interface. If the SGs interface is supported but the Gs interface is not supported, even if the UE and the network Supports ISR activation judgment conditions such as ISR function...

[0124] In this embodiment, the ISR activation judging network element dynamically obtains SGs / Gs related information through the ISR activation process, and the SGs / Gs related information is the information on whether the network element of the context request responder has established the SGs / Gs association relationship.

[0125]SGSN / MME carries the information of whether the Gs / SGs association relationship has been established in the context response message to the MME / SGSN; when MME / SGSN judges whether to activate the ISR, it judges whether the SGs and Gs association relationships will be established; if the SGs is established In the case of an association relationship, the Gs association relationship is not established, and the ISR is not activated even if the ISR activation judgment condition such as that both the UE and the network support the ISR function are met.

Abstract

The invention relates to a method and a system for determining activation of signaling-saving function in idle mode. The method comprises the following steps that: after receiving an update request of a routing area or a tracking area sent by a terminal, a signaling-saving ISR activation determining network element in idle mode sends a context request to a response side of the context request; after receiving a context response sent by the response side of the context request, the ISR activation determining network element determines that ISR function is not activated when meeting the following conditions that an MME works in a mode supporting an SGs interface and an SGSN works in a mode not supporting the SGs interface, or the MME establishes SGs correlation and the SGSN does not establish SGs correlation; moreover, the ISR activation determining network element and the response side of the context request are respectively one of the mobility management entity (MME) and the general packet radio service support node (SGSN). The method and system of the invention solve the problem that an MSC / VLR probably cannot realize UE paging after introducing the ISR function.
