[0098] In some embodiments, as shown in FIG. IB, in satellite access, the satellite can operate in a regenerative mode, FIG. IB shows a reference architecture. If the satellite operates in a regenerative mode, the satellite works together with a base station (eNB); the satellite payload performs all or part of the functions of the eNB. The satellite radio interface transmits data of S1, S1-MME and / or S1-U interfaces between the ground evolved packet core network (EPC) and the satellite eNB.

[0099] In some embodiments, if the satellite type is a Non-Geostationary Orbit (NGSO) satellite, it means that the eNB on the satellite serving the UE will move with the satellite. As shown in FIG. 1C: NB-IoT UE uses LEO constellation to access EPC. At time T1, satellite 1 (SAT-1) flies into the area of the UE and provides coverage to the UE. At time T2, satellite 1 flies out of the coverage area of the UE, while satellite 2 (SAT-2) flies into the coverage area of the UE. To ensure service continuity during satellite movement, the X2-based or S1-based handover process can be enhanced to be reused for satellite movement scenarios that support such service continuity. This can be applied to any type of terminal in addition to NB-IoT UE, such as mobile phones, MTC, LTE-M, etc. Alternatively, NB-IoT UE, which can be for NB-IoT terminals.

[0100] Since NB-IoT UE does not support mobility, the handover procedure in the related art cannot be applied to terminals using NB-IoT access. If the NB-IoT UE uses satellite access in a regenerative mode, since the eNB / gNB serving the UE access is constantly changing with the movement of the satellite, the NB-IoT UE cannot guarantee the continuity of service in the satellite access network based on the prior art. To overcome the problem, the embodiments of the present disclosure propose a method for NB-IoT UE to access using a satellite network in a regenerative mode to ensure the continuity of NB-IoT UE access in the case of satellite movement.

[0279] Optionally, the NB-IoT UE accesses the EPC through the SAT-eNB1, and downlink data is transmitted to the NB-IoT UE by the P-GW, the source S-GW, and the SAT-eNB1. Over time, the SAT-eNB1 will fly out of the coverage area of the UE, and the SAT-eNB1 decides to initiate S1-based handover to the SAT-eNB2. Here, the trigger can be due to the absence of an X2 connection to the target base station (eNodeB / SAT-eNB2) or an error indication from the target base station after the X2-based handover is unsuccessful.

[0280] In step S5202, the SAT-eNB1 sends a handover request to the source MME.

[0281] Optionally, the handover request includes a target TAI and indication information indicating that the NB-IoT UE uses satellite access in a regeneration mode; the target TAI is used for the source MME to select a suitable target MME; and the indication information is used to indicate that the satellite base station is working in the regeneration mode.

[0286] Optionally, the source MME selects the target MME based on the MME selection function, and sends a forward relocation request message to the target MME, the forward relocation request including the MME UE context, the identity (e.g. base station identity) of the target SAT-eNB2, and / or the target TAI, etc., and the forward relocation request is used to indicate that the handover is triggered by satellite movement.

[0288] Optionally, the target TAI is used by the target MME to determine whether a redirection of the S-GW is needed (i.e. whether a target S-GW needs to be determined).

[0289] At step S5205A, the target MME sends a create session request message to the target S-GW.

[0290] Optionally, the MME is redirected (i.e. the target MME is determined), and the target MME authorizes the handover if it determines that the handover is triggered by satellite movement. Optionally, the create session request message is the fourth request in the previous embodiments.

[0293] Step S5205B, the target S-GW sends a create session request response to the target MME.

[0294] Optionally, the create session request response can be the fourth response in the previous embodiments.

[0295] Step S5206, the target MME sends a handover request message to the SAT-eNB 2.

[0296] Optionally, the handover request message creates a UE context in the SAT-eNB 2, including information about the bearers and security context. The handover request message can be the first message in the previous embodiments.

[0297] Step S5207, the SAT-eNB 2 sends a handover request acknowledgement message to the target MME.

[0310] Step S5212, the SAT-eNB1 sends a Handover Command to the NB-IoT UE.

[0311] Compared with the S1-based handover procedure in the related art, the UE (NB-IoT UE) does not need to initiate a tracking area update procedure subsequently when receiving the Handover Command from the SAT-eNB1 (source base station) according to the embodiments of the present disclosure.

[0312] Embodiment Three:

[0313] Embodiment Three describes that the source base station (e.g. SAT-eNB1) provides current coverage, and after the SAT-eNB1 loses coverage, the target base station (e.g. SAT-eNB2) continues to provide coverage for the area. After the coverage of the SAT-eNB1 is switched to the coverage of the SAT-eNB2, the corresponding MME and S-GW do not change.

[0314] FIG. 5C is a flow diagram of an information processing method according to an embodiment of the present disclosure. As shown in FIG. 5C, the embodiments of the present disclosure relate to an information processing method, which comprises:

[0315] Step S5301, sending downlink data to the NB-IoT UE through the P-GW, the S-GW and the SAT-eNB1.

[0316] Optionally, the NB-IoT UE accesses the EPC through the SAT-eNB1; the downlink data is sent to the NB-IoT UE through the P-GW, the S-GW and the SAT-eNB1. With the passage of time, the SAT-eNB1 will fly out of the coverage area of the UE, and the SAT-eNB1 decides to initiate the S1-based handover to the SAT-eNB2. Here, the trigger can be due to no X2 connection to the target base station (eNodeB / SAT-eNB2) or an error indication from the target base station after the X2-based handover is unsuccessful.

[0317] Step S5302, the SAT-eNB1 sends a handover request to the MME.

[0318] Optionally, the handover request includes a target TAI and indication information indicating that the NB-IoT UE uses satellite access in the regeneration mode; the target TAI is used for the source MME to select a suitable target MME; the indication information is used to indicate to the satellite that the satellite-based base station is working in the regeneration mode.

[0319] Step S5303, the MME authorizes the handover.

[0320] Optionally, the source MME determines that the NB-IoT UE is in the regeneration mode and the access type of the NB-IoT (LEO) based on the handover request received from the SAT-eNB1, and then determines that the handover is triggered by the satellite movement instead of the NB-IoT UE movement; the MME authorizes the handover. Here, the source MME and the target MME are the same MME, i.e., both are the MME.

[0321] Step S5304A, the MME sends a create session request message to the S-GW. Optionally, the create session request message is the fourth request in the previous embodiment.

[0322] Optionally, the MME sends a create session request message to the S-GW for each PDN connection.

[0331] Step S5308, the SAT-eNB 1 sends a handover command to the NB-IoT UE.

[0332] Compared with the S1-based handover procedure in the related art, in the embodiments of the present disclosure, after receiving the handover command from the SAT-eNB 1 (source base station), the UE (i.e., the NB-IoT UE) does not need to subsequently initiate a tracking area update procedure.
