Problems solved by technology

Since the terminal may establish connections with multiple base stations, the network side does not know the base station corresponding to the random access report reported by the terminal
In addition, for carrier aggregation (CA), since the terminal may also initiate random access on multiple carriers, based on the currently reported random access report, it is difficult to distinguish which carrier the random access is initiated on

Embodiment Construction

[0060] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0061] For dual connectivity, due to the difference between the main base station (MeNB) and the secondary base station (SeNB), if the network side can distinguish the main base station and the secondary base station according to the random access report (RACH-report), it will help the network to locate the random access (RACH) problem. For CA, similarly, if the network can distinguish which carrier the RACH is on, it will also help the network location problem.

[0062] Please refer to figure 1 The embodiment of the present invention provides a method for obtaining a connection state of a terminal in a multi-connection scenario, which is applied between the network side and the terminal, where the terminal establishes connections with multiple base sta...

Abstract

The embodiment of the invention provides a method and device for obtaining the connection state of a terminal in a multi-connection scene, and the method comprises the steps that a network side transmits a request message to the terminal, and the terminal is connected with a plurality of base stations, wherein the request message is used for requesting a random access state of a preset base station, and the preset base station is a base station which is appointed by the network side and the terminal or is a base station specified in the request message; the network side receives a response message returned by the terminal for the request message, wherein the response message comprises a random access report among the preset base stations. The method can enable the network side to obtain the specific connection state information of the terminal.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, and in particular to a method and device for acquiring terminal connection status in a multi-connection scenario. Background technique [0002] Hotspot coverage is the focus of Long Term Evolution (LTE) systems. It is estimated that since most (such as 90%) of the business takes place indoors and in hotspot areas, smallcells for solving hotspot coverage and providing high-speed access have been proposed, and have been proposed in the 3rd Generation Partnership Project (3GPP) wireless access The network access (RAN) plenary meeting established the project, and most operators and manufacturers paid close attention to and actively participated in it. SmallCell refers to various wireless access points with low power, small coverage, and flexible deployment. The main significance of Smallcell enhancement lies in its large-scale deployment. Since the number of smallcells under a...
