Description
Technical Field
The present invention relates to information acquisition technologies, and in particular, to a method and a system for a CS (Circuit Switched) domain control network element to acquire information of a PS (Packet Switched) domain control network element.
Background
With the development of mobile communication technology and the evolution of core networks, 2G/3G networks have emerged and gradually evolved to 4G networks. Both 2G/3G and 4G networks will coexist for a period of time. Generally speaking, there are two types of circuit switched services and packet switched services in the existing network, and accordingly, the control network elements of the core network are also divided into two types, namely CS domain control network elements and PS domain control network elements.
The background network related by the invention is a mobile communication network which is composed of a base station subsystem, a CS domain control network element, a PS domain control network element and the like. Fig. 1 shows a schematic architecture diagram of a background network, and various network elements in the background network are described as follows:
the terminal 101: such as a UE (User Equipment). The terminal is responsible for interaction with the user; and can access the network through different access modes such as PS/CS, etc., to replace the user to establish the session.
Base station subsystem 102: such as a Base Station subsystem including a BSC (Base Station Controller) and a BTS (Base Transceiver Station), or a Base Station subsystem including an RNC (Radio network Controller) and a Node B (Node B).
CS domain controlling network element 103: a control unit of the CS domain core network, such as an MSC (mobile switching center), or an MSCServer (mobile switching center server), etc.
PS domain controlling network element 104: a control unit of the PS domain core network, such as an SGSN (Serving GPRS support node), an MME (Mobile Management Entity), or the like.
The terminal can be accessed to the CS domain to establish a channel with the CS domain control network element, and can also be accessed to the PS domain to establish a channel with the PS domain control network element. In addition, the terminal may establish a connection with the CS domain or the PS domain, respectively, or may establish a connection with the CS domain and the PS domain simultaneously.
In some scenarios, the CS domain controlling network element needs to acquire information of the PS domain controlling network element. The information of the PS domain controlling network element may be information for directly positioning the PS domain controlling network element, such as a number, an address, or an identifier of the PS domain controlling network element, or may be information for indirectly positioning the PS domain controlling network element, such as index information of the PS domain controlling network element, or any combination of the above information. For example, the information of the PS domain controlling network element may be: the address, name, Identity, P-TMSI (packet Temporary mobile subscriber Identity), TLLI (Temporary Logical Link Identity), GUTI (global Unique Temporary subscriber Identity), or GUMMEI (global Unique MME Identity) of the PS domain controlling network element.
In the prior art, a CS domain control network element queries an HSS/HLR (home subscriber server/home location register) to obtain information of a PS domain control network element. As shown in fig. 2, a process of acquiring information of a PS domain control network element by a CS domain control network element in the prior art includes:
step 201, the PS domain control network element reports its own information to the HSS/HLR.
Step 202, the HSS/HLR stores the received information of the PS domain control network element.
In step 203, the HSS/HLR returns a response message to the PS domain control network element.
Step 204, when the information of the PS domain control network element changes, the PS domain control network element reports the latest information of the PS domain control network element to the HSS/HLR.
Step 205, the HSS/HLR updates the information of the PS domain control network element.
In step 206, the HSS/HLR returns a response message to the PS domain control network element.
Step 207, the CS domain controlling network element queries the information of the PS domain controlling network element from the HSS/HLR.
And step 208, the HSS/HLR returns the query result carrying the information of the PS domain control network element to the CS domain control network element.
In the existing protocol, the HSS/HLR does not support to notify the CS domain control network element of the information of the PS domain control network element, so in order to apply the procedure shown in fig. 2, the prior art needs to modify the HSS/HLR, and modify the query message between the HSS/HLR and the CS domain control network element so that the query message can carry the information of the PS domain control network element, thereby implementing that the HSS/HLR notifies the CS domain control network element of the information of the PS domain control network element in the query process. In addition, when the CS domain controlling network element serving the terminal is far away from the HSS/HLR, if the CS domain controlling network element obtains the information of the PS domain controlling network element according to the flow shown in fig. 2, the performance of the service processing may be affected.

The switching process through the core network can be a switching process through a CS domain control network element or a PS domain control network element; a handover procedure via a CS domain controlling network element, i.e. via a core network, is shown here.
Step 705, the CS domain control network element parses the information for positioning the target base station subsystem in the handover request message without parsing the information of the PS domain control network element, and forwards the handover request message carrying the information of the PS domain control network element to the base station subsystem 2 according to the information for positioning the target base station subsystem;

To this end, the base station subsystem 2 may obtain information of the PS domain control network element.
Step 706, the base station subsystem 2 sends a handover response message to the CS domain control network element.
