The Evolved Universal Mobile Telecommunication System Territorial Radio Access Network (E-UTRAN) and the System Architecture Evolution (SAE) scheme evolved on the mobile core network. Evolved Packet Core (EPC). In the LTE/SAE architecture, the EPS network only provides packets because some operators want to provide voice services by the traditional 2/3G radio access network and Circuit (CS) domain core network after deploying the EPS network. Packet Switching (PS) domain data service access, the EPS network coexists with the traditional 2/3G circuit domain core network for a period of time.

Step 202: The core network node device or other access control node device determines that the private message needs to be transited according to the foregoing transit identifier, and forwards the private message to the target access control node device corresponding to the target node device ID.

In this step, if the core network node device determines that the private message is not required according to the foregoing transit identifier To transit, the private message content information carried in the private message is further parsed according to a preset policy of the manufacturer.

In this embodiment, when the source eNB in the E-UTRAN delivers a private message to the target RNC in the UTRAN, the source eNB sends a private message to be transmitted to the MME to which the MME belongs, through the S1 interface, and the relay carried in the private message The identifier is an identifier indicating that the relay needs to be transferred, and the target node device ID is the identifier of the target RNC. The identifier of the target RNC may be a Location Area Identity (LAI) and a target RNC-ID. After receiving the private message, the MME determines that the transit is required according to the transit identifier, and sends the private message to the SGSN or MSC to which the location area (LA) corresponding to the target LAI belongs according to the target LAI. After receiving the private message, the SGSN or the MSC determines that the transit is required according to the transit identifier, and sends the private message to the target RNC corresponding to the target RNC-ID through the IU interface according to the target LAI and the target RNC-ID, so that the target RNC can obtain the target RNC. The private message sent by the source eNB improves the processing efficiency of the private message. The sending of the message flow in turn corresponds to the RNC in the UTRAN to the eNB in the E-UTRAN, and will not be described here.

In this example, if there is an X2 interface between eNB1 and eNB2, and eNB2 and eNB3 have an x2 interface, but there is no X2 interface between eNB1 and eNB3, then when eNB1 wants to send a private message to eNB3, it can pass the S1 interface. The MME relay can also be transferred through the eN B2 of the X2 interface. A similar process is also adapted to the IUR interface between RNCs.

>>> Routing Area Code (RAC) Optional (0) Step 302: The core network node device or other access control node device determines that the private message needs to be transferred according to the target node device ID, and the target corresponding to the target node device ID is connected. The incoming control node device forwards the above private message.

In this step, if the core network or other access control node device determines that the private message does not need to be transferred, that is, the target node device ID is its own ID, according to the target node device ID, the private message is further parsed according to a preset policy of the manufacturer. Private message content information carried in.

In this embodiment, when the source eNB in the E-UTRAN delivers a private message to the target RNC in the UTRAN, the source eNB sends a private message to be transmitted to the MME to which the MME belongs, through the S1 interface, and the target carried in the private message. The node device ID is the identifier of the target RNC. The identifier of the target RNC may be the LAI and the target RNC-ID. After receiving the private message, the MME determines that the relay needs to be transferred according to the target LAI and the target RNC-ID, and sends the private message to the SGSN or MSC to which the LA corresponding to the target LAI belongs according to the target LAI. After receiving the private message, the SGSN or the MSC determines that the transit is required according to the target LAI and the target RNC-ID, and sends the private message to the target RNC corresponding to the target RNC-ID through the IU interface according to the target LAI and the target RNC-ID, thereby The target RNC can acquire the private message sent by the source eNB, thereby improving the processing efficiency of the private message. The sending of the message flow in turn corresponds to the RNC in the UTRAN to the eNB in the E-UTRAN, and will not be described here.

In this example, if there is an X2 interface between eNB1 and eNB2, and eNB2 and eNB3 have an x2 interface, but there is no X2 interface between eNB1 and eNB3, then when eNB1 wants to send a private message to eNB3, it can pass the MME of the S1 interface. Transit, can also pass eNB2 through X2 interface Transit. A similar process is also adapted to the IUR interface between RNCs.
