Problems solved by technology

According to the implementation of the existing technology and the above-mentioned multi-connection operation, it is possible for the UE to have no service interruption during the mobility event, but for the multi-connection UE, the anchor point will not be kept unchanged, which will bring many disadvantages to the system The result, such as too long transmission path, too concentrated processing load, etc., thus degrading the performance of the whole system
With the continuous evolution of the network, the mobile events between nodes under the traditional network architecture cannot meet the higher requirements for mobile performance

[0136] Such as Figure 4 As shown, the embodiment of the present invention provides a handover method of a network entity, including:

[0137] Step 41: Receive a new configuration parameter of a second network entity that maintains connection with the terminal sent by the first network entity that maintains connection with the terminal. It is sent by a network entity to configure the instruction information of the anchor point change operation from the first network entity to the second network entity;

[0138] Step 42: When the new configuration parameters take effect, do not perform reset / or reconstruction of underlying transmission, and send an anchor point change confirmation message to the second network entity.

[0139] In this embodiment, the trigger conditions for the new configuration parameters of the terminal to take effect include:

[0140] 1) When the terminal receives the new configuration parameter, it takes effect immediately, and sends a trigger message to n...

Abstract

The invention discloses a network entity switching method, a terminal, and network entity equipment. The network entity switching method comprises steps that new configuration parameters of a second network entity connected with the terminal, which are transmitted by a first network entity connected with the terminal, are received; the new configuration parameters are transmitted by the second network entity according to indication information, which is transmitted by the first network entity, and is configured to switch an anchor point from the first network entity to the second network entity; when the new configuration parameters come into force, resetting and / or rebuilding of underlying transport are / is prevented, and an anchor point switching confirmation message is transmitted to thesecond network entity. By adopting the abovementioned technical scheme, seamless transfer of business data can be guaranteed, and therefore negative influences on a system are improved.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method for network entity switching, a terminal and network entity equipment. Background technique [0002] After the UE (User Equipment) moves to the signal coverage overlap of two network entities (eNB, evolved Node B), the network will trigger a mobility event, such as figure 1 As shown, it is a common dual connectivity mobile scenario, and the UE maintains wireless connections with both the first eNB and the second eNB. [0003] figure 2 For the traditional handover process, including: [0004] 0. Regional restriction setting between source eNB and target eNB, MME (Mobility Management Entity) and SG (Serving Gateway); [0005] 1. The source eNB sends measurement control to the terminal, the terminal transmits data packets with the source eNB, transmits data packets between the source eNB and the serving gateway, and the source eNB performs uplink configur...
