Method and device for managing dual-connection ENDC link

Abstract

The invention relates to the field of communication, in particular to a method and device for managing a dual-connection ENDC link. The method is used for ensuring the continuity of service transmission. The method comprises the following steps of: through OM, receiving link state description information sent by DD, judging an establishment state of a SCTP link, when it is determined that the establishment state of the SCTP link is not established and the link of the ENDC type needs to be established, establishing a SCTP link of the ENDC type, and when it is determined that the connection state of the SCTP link is disconnected and the link of the ENDC type needs to be deleted, deleting the SCTP link of the ENDC type so that the OM can finish the management of the SCTP link of the ENDC typebased on the received link state description information and the 5G GNB can transmit the user service by using the core network of the LTE ENB, and thus the service is not interrupted, the utilization rate of wireless resources is improved, the high-capacity requirement of a user is met, and the systematicness is further improved.

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
