Embodiment 1

[0060] Embodiment 1 takes the attachment process of the PS domain as an example, and describes a method for the terminal and the base station subsystem to obtain the information of the control network element of the PS domain. Wherein, the base station subsystem obtains the information of the PS domain control network element during the process of selecting the PS domain control network element serving the terminal; the terminal obtains the information of the PS domain control network element when receiving the attach acceptance message. Such as image 3 As shown, the attach process includes:

[0061] In step 301, the terminal sends a wireless connection establishment request message to the base station subsystem, requesting to establish a wireless connection between the terminal and the base station subsystem.

[0062] Step 302, the base station subsystem sends a wireless connection establishment response message to the terminal, allowing the establishment of a wireless conn...

Embodiment 2

[0075] Embodiment 2 describes that after the terminal obtains the information of the control network element in the PS domain, it sends the information of the control network element in the PS domain to the base station subsystem during the establishment of the wireless connection; the base station subsystem sends a message to the control network element in the CS domain , the information of the control network element in the PS domain is carried in the sent message. Such as Figure 4 As shown, the process for the CS domain control network element in Embodiment 2 to obtain the information of the PS domain control network element includes:

[0076] Step 401, the terminal obtains the information of the PS domain control network element;

[0077] For example, the terminal can obtain the information of the PS domain control network element from the initial configuration; or obtain the information of the PS domain control network element during the location update process; or obta...

Embodiment 3

[0094] Embodiment 3 describes that the terminal obtains the information of the control network element in the PS domain, and after the terminal establishes a wireless connection with the base station subsystem, the terminal sends the information of the control network element in the PS domain to the base station subsystem through a message on the wireless side. Such as Figure 5 As shown, the process for the CS domain control network element in Embodiment 3 to obtain the information of the PS domain control network element includes:

[0095] Step 501, the terminal obtains the information of the PS domain control network element;

[0096] For example, the terminal can obtain the information of the PS domain control network element from the initial configuration; or obtain the information of the PS domain control network element during the location update process; or obtain the PS domain control network element information during the attachment process of the PS domain as shown ...

Abstract

The invention discloses a method and system for a CS domain control network element to obtain information of a PS domain control network element. The method includes: the base station subsystem obtains the information of the PS domain control network element, and sends the obtained information of the PS domain control network element to the CS domain control network element; or, the base station subsystem obtains the information of the PS domain control network element , and during the handover process, the information of the PS domain control network element is sent to the target base station subsystem; the target base station subsystem sends the information of the PS domain control network element to the CS domain control network element. The present invention can be used without modifying the HSS / HLR and the query messages between it and the CS domain control network element.

Description

technical field [0001] The present invention relates to information acquisition technology, in particular to a method and system for obtaining information of PS (Packet Switched, Packet Switched) domain control network elements by CS (Circuit Switched, Circuit Switched) domain control network elements. Background technique [0002] With the development of mobile communication technology and the evolution of the core network, 2G / 3G networks emerged and gradually evolved to 4G networks. 2G / 3G and 4G networks will coexist for a period of time. Generally speaking, there are two types of circuit switching services and packet switching services in the existing network. Correspondingly, the control network elements of the core network are also divided into two types: CS domain control network elements and PS domain control network elements. [0003] The background network involved in the present invention is a mobile communication network composed of a base station subsystem, CS d...
