A management method and device for a dual-connection endc link

Abstract

The present invention relates to the communication field, in particular to a management method and device for a dual connection ENDC link. It is used to ensure the continuity of service transmission. The method is: OM receives the link status description information sent by DD, judges the establishment status of the SCTP link, and determines that the establishment status of the SCTP link is not established, and the ENDC type needs to be established When the link is connected, an SCTP link of type ENDC is established, and the connection status of the SCTP link is determined to be disconnected. If the link of type ENDC needs to be deleted, the SCTP link of type ENDC is deleted. In this way, OM can complete the management of ENDC-type SCTP links based on the received link status description information, and 5G GNB can use the core network of LTE ENB to transmit user services, ensuring uninterrupted services and improving the utilization of wireless resources , to meet the high-capacity needs of users, and further improve the system.

Description

technical field [0001] The present invention relates to the communication field, in particular to a management method and device for a dual connection ENDC link. Background technique [0002] Long Term Evolution (LTE) is a UMTS (Universal Mobile Telecommunications System, Universal Mobile Communications System) technical standard formulated by 3GPP (The 3rd Generation Partnership Project, Third Generation Partnership Project). The LTE system network architecture is flatter and simpler It reduces network nodes and system complexity, thereby reducing system delay, network deployment and maintenance costs. [0003] With the rapid development of mobile communication technology, the fifth generation mobile communication (Fifth Generation, 5G) system has begun to be put into the market, but the 5G system cannot completely replace the LTE system.

Problems solved by technology

[0003] With the rapid development of mobile communication technology, the fifth generation mobile communication (Fifth Generation, 5G) system has begun to be put into the market, but the 5G system cannot completely replace the LTE system. In the multi-base station communication scenario where the 5G system and the LTE system share the LTE core network , the 5G system needs to use the existing facilities of the LTE system to provide services for users and meet the business needs of users. Therefore, there will be a phenomenon of coexistence of the 5G system and the LTE system. However, there are currently two main transmission links in the LTE system. In other words, the S1 link from the base station to the core network and the X2 link from the base station to the base station, the existing solution has not yet established a transmission link between the 5G base station and the LTE core network, and the 5G system cannot use the core network of the LTE system to Transmitting all radio resource control (Radio Resource Control, RRC) messages, resulting in the user being unable to access the network

[0004] In addition, with the increase of demand for offloading in hotspot areas, dense networking is becoming more and more common as a common expansion method. Since multiple cells or base stations are concentrated in dense sites, if users frequently switch base stations when moving in dense sites, it will not only bring The interference problem may also affect the handover performance, cause call drop, fail to meet the user's capacity and coverage requirements, and reduce service reliability
