Embodiment 1

[0075] In this embodiment, the eNB uses the original radio resource allocation message to send the 2G / 3G CS domain registration information to the UE. When sending the original radio resource establishment / reconfiguration message, the information in the message can be redefined. Element (IE), the redefined IE is used to carry location update related information, specifically, radio resource setup / reconfiguration messages include: Radio bearer setup, Radio bearer reconfiguration, Transport channel reconfiguration and Physical channel reconfiguration. There is an optional IE in these four messages, that is, CN Information info. The two IEs, CN CommonGSM-MAP NAS system information and CS domain specific system information contained in this IE, are redefined to carry the location update information corresponding to the eNB. Information, including LAI, T3212, ATT.

[0076] Such as Figure 2B shown, for Figure 1A and Figure 1B In the case where the MME is connected to the MSC th...

Embodiment 2

[0083] In this embodiment, the eNB sends 2G / 3G registration information to the UE by adding a new message, such as Figure 2D shown, for Figure 1A and Figure 1B In the case where the MME is connected to the MSC through the IWE, the specific process of UE registration in 2G / 3G in this embodiment includes:

[0084] Step 221: The eNB judges that the voice call carried by SAE / LTE has been established. One of the methods is to check whether there is media data in the RLC receiving buffer of the bearer. If there is, the voice call is considered to be established;

[0085] Step 222: The eNB sends a newly defined notification message (CS information) to the UE, and the message carries location update information corresponding to the eNB;

[0086] Step 223: When the UE receives the notification message, it records the location update related information in the notification message, and sends a location update request according to the LAI stored in the SIM / USIM and the received locat...

Embodiment 3

[0089] In this embodiment, the MME sends 2G / 3G registration information to the UE by adding a new message, such as Figure 2F shown, for Figure 1A with Figure 1B In the case where the MME is connected to the MSC through the IWE, the specific process of UE registration in 2G / 3G in this embodiment includes:

[0090] Step 241: MME judges that the voice call carried by SAE / LTE is established;

[0091] Step 242: The MME sends a notification message (CS information) to the UE, and the message carries location update related information corresponding to the MME;

[0092] Step 243: When the UE receives the notification message, it records the location update related information in the notification message, and sends a location update request according to the LAI stored in the SIM / USIM and the received location update related information, and the request is sent via The eNB, MME and IWE arrive at the MSC, and the MSC performs location update according to the request, completes the ...

Abstract

The embodiment of the invention discloses a method for location updating by a terminal which is accessed in an SAE / LTE network. The method comprises: when determining that the terminal needs to update location to the 2G / 3G network, the node of the SAE / LTE network sends location updating relevant information to the terminal; when the terminal receives the location updating relevant information, location updating in the 2G / 3G network is realized by a network interconnection entity of the SAE / LTE network and the 2G / 3G network according to the location updating relevant information. The embodiment of the invention also discloses a system for location updating by a terminal and a device thereof. By adopting the invention, the terminal accessed in the SAE / LTE network can obtain the location updating relevant information, so as to initiate Update location to the 2G / 3G network according to the location updating relevant information.

Description

technical field [0001] The present invention relates to the field of mobile communication, in particular to a method, system and device for terminal location update. Background technique [0002] After years of deployment, the second / third generation (2G / 3G) mobile communication network can be regarded as a comprehensive coverage to some extent. With the development of system architecture evolution / long-term evolution (SAE / LTE) network technology With the development, the SAE / LTE network has covered some urban areas and traffic hot spots, making SAE / LTE network and 2G / 3G network coexist in the current communication network. [0003] According to different network bearer mechanisms, mobile communication voice calls can be divided into the following categories: [0004] The first type is conversational services carried by the circuit (CS) domain, such as voice calls; [0005] The second type is the session service carried by the Packet Switching (PS) domain, also known as Vo...
