Problems solved by technology

[0005] When the UE is at the edge of the cell, the signal quality will be affected. During the initial access, if the UECapabilityInformation is too long, it will increase the difficulty and time of transmitting the message to the base station, and it will easily cause retransmission, which increases the probability of access failure and prolongs the The time of the initial attachment process of the multimode terminal

Embodiment Construction

[0028] The following will clearly and completely describe the technical solution of the present invention in conjunction with the accompanying drawings of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0029] In the embodiment of the present invention, the system capability of the multimode terminal is the capability corresponding to the system that the multimode terminal currently accesses the base station, and the different system capability of the multimode terminal is the capability supported by the multimode terminal other than the system capability. other abilities.

[0030] Such as image 3 As shown, it is a schematic flowchart of a multi-mode terminal capability acquisiti...

Abstract

The invention discloses a capability acquisition method for a multimode terminal. The method comprises the following steps that a base station transmits a first terminal capability request to the multimode terminal according to the type of a current system to acquire the current system capability of the multimode terminal after receiving an attachment request sent by the multimode terminal; and the base station processes initial attachment initiated by the multimode terminal according to the system capability. According to the method, the multimode terminal can only report the capability of the multimode terminal for the current system in an initial attachment process, so that the number of bytes of a multimode terminal capability reporting message is reduced, the multimode terminal capability reporting message transmission failure rate and retransmission times in the initial attachment process are reduced, and the access time delay of the multimode terminal is further shortened.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular to a multi-mode terminal capability acquisition method, system and base station. Background technique [0002] During the initial attachment process of the LTE (Long Term Evolution, Long Term Evolution) system, the largest air interface message that the UE sends uplink on the air interface is a UE capability report message (UECapabilityInformation). Such as figure 1 As shown, it is a schematic diagram of the flow of the base station obtaining UE capabilities through the air interface message. When the UE initially attaches, the base station RRC (Radio Resource Control, radio resource control) receives the initial context establishment message of the core network and finds that there is no core network saved message. UE capability, it will send a UE capability request message on the air interface to obtain all RAT (Radio Access Type, wireless access type) types ...
