Method for acquiring terminal wireless capability information, core network entity, base station and terminal

Abstract

Embodiments of the present invention relate to a method for acquiring terminal wireless capability information, a core network entity, a base station and a terminal. When the first terminal changes from the first communication path through which the first terminal directly accesses the network to the second communication path through which the first terminal accesses the network through the second terminal, the first terminal receives the first message sent by the base station for Acquiring the wireless capability information of the first terminal, and then sending the wireless capability information of the first terminal to the base station, wherein the wireless capability information includes connection mode information between the first terminal and the second terminal and identification information of the second terminal, or, the first terminal The wireless capability information includes connection mode information between the first terminal and the second terminal and wireless capability information of the second terminal. In this method, when the first terminal changes between accessing the network independently and through a relay terminal, the network side can obtain the wireless capability information of the first terminal according to the access mode of the first terminal, so as to set the Best quality of service.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a method for acquiring terminal wireless capability information, a core network entity, a base station and a terminal. Background technique [0002] Today's smartphone industry is mature, the market is about to become saturated, and the access and data card markets have declined. Wearable devices are one of the future strategic directions of various companies. At present, the industry has launched a watch that can be installed with a subscriber identity module (English: subscriber identity module, SIM) card, so that the watch can be directly connected to the network. Due to the size limitation of wearable devices, wearable batteries and antennas are the main problems affecting wearable devices: small battery capacity, direct communication with the base station network will lead to fast battery consumption and short standby time; wearable devices generally have specia...

Problems solved by technology

Due to the size limitation of wearable devices, wearable batteries and antennas are the main problems affecting wearable devices: small battery capacity, direct communication with the base station network will lead to fast battery consumption and short standby time; wearable devices generally have special shapes, Antenna design is difficult. At present, only a single antenna can be realized. Therefore, compared with multi-antenna devices, such as mobile terminals, it takes more time and consumes a lot of network resources to send the same amount of data.

However, when the wearable device changes between accessing the network independently and accessing the network through a relay terminal, since the wearable device does not notify the network that its ability to access the network has changed, the network side It is impossible to provide the best QoS for wearable devices according to the access method of wearable devices. Among them, QoS refers to a network that can use various basic technologies to provide better service capabilities for specified network communications. It is a security mechanism of the network , is a technology that can solve problems such as network delay and congestion

[0004] It can be seen that the network in the prior art cannot provide the wearable device with the best transmission rate according to the access method of the wearable device, that is, the network cannot provide the wearable device with the best transmission rate according to the access method of the wearable device QoS
