Embodiment 1

[0035] refer to figure 2 , shows a flow chart of steps of a terminal handover method according to Embodiment 1 of the present invention.

[0036] The terminal handover method of this embodiment is used for terminal handover in a base station without MME mode, including the following steps:

[0037] Step S102: the target BPOE of the base station receives the handover notification message.

[0038] Wherein, the handover notification message is used to notify the UE to handover from the source BPOE to the target BPOE of the base station.

[0039] In this embodiment, the handover notification message is sent by the upper layer of the base station, wherein the upper layer of the base station adopts the conventional meaning in this field, including PDCP (Packet Data Convergence Protocol, packet data convergence protocol) layer and RLC (Radio Link Control, wireless link control) layer.

[0040] Step S104: the target BPOE sends an ARP message to the service server to notify the se...

Embodiment 2

[0050] refer to image 3 , shows a flow chart of steps of a terminal handover method according to Embodiment 2 of the present invention.

[0051] In this embodiment, the source BPOE of the base station is set to be BPOE1, and the target BPOE is set to BPOE2. Taking UE switching from BPOE1 to BPOE2 as an example, the terminal switching solution of the present invention is described.

[0052] The terminal handover method of this embodiment is used for terminal handover in a base station without MME mode, including the following steps:

[0053] Step S202: the base station establishes an initial link from the UE to the service server via the BPOE1.

[0054] The eNodeB provides a transparent transmission channel for the UE and the service server. In the initial stage, if the UE is attached to the cell covered by BPOE1, the eNodeB sends the information of the UE and the service server (including the IP address of the UE, the IP address of the service server, gateway, code, etc.) o...

Embodiment 3

[0075] refer to Figure 4 , which shows a processing flow chart of terminal handover at the source side according to Embodiment 3 of the present invention.

[0076] This embodiment describes the terminal handover scheme of the present invention from the source BPOE side. The source-side terminal handover processing flow in this embodiment is used for the source-side processing of the terminal handover in the base station in the non-MME mode. The flow includes:

[0077] Step S302: The source-side BPOE board DD (Device Driver, device driver layer in the eNodeB) receives the initialization link establishment message sent by the HL.

[0078] Step S304: The DD of the source-side BPOE configures UE and service server information, including UE's IP address, Server's IP address, gateway, and mask.

[0079] Step S306: The DD of the source BPOE sends an ARP request to the service server to initiate an ARP learning process.

[0080] Step S308: The DD of the source BPOE receives the ARP...

Abstract

The invention provides a terminal switching method and a base station. The terminal switching method is used for intra-base-station terminal switching in an MME mode and comprises the steps that a BPOE of the base station receives a switching notification message; a target BPOE sends an ARP message to a service server to inform the service server of active updating of a saved ARP table; after the updating of the ARP table is accomplished by the service server, the target BPOE receives a message, sent to UE by the service server and cached in a source BPOE, from the source BPOE, and a message sent to the UE by the service server through the target BPOE is cached; the target BPOE sends the message received from the source BPOE to the UE firstly after receiving a switching completion message and then sends the message sent to the UE by the service server through the target BPOE to the UE. According to the terminal switching method and the base station, a transmission channel for switching can be provided fast, interruption of service during switching is avoided, and certain transmission rate is maintained.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a method for switching terminals in a base station in a mode without MME (Mobility Management Entity, Mobility Management Entity) and the base station. Background technique [0002] In the TD-LTE (Time Division-Long Term Evolution, Time Division Long Term Evolution) system, the communication between the terminal and the terminal and between the terminal and the service server is through eNodeB (base station) and EPC (Evolved Packet Core, evolved packet core) Open up the transmission path; and the service transmission between eNodeB and EPC is carried by GTP-U (GPRS Tunneling Protocol User, GPRS Tunneling Protocol User plane) message. In the scenario of no MME and no EPC, the eNodeB independently opens the path between the terminal and the terminal and between the terminal and the service server. [0003] In the communication between the terminal and the service ...
