Description
Technical Field
The invention relates to the technical field of communication, in particular to a verification method and a base station for UE capability information report based on LTE.
Background
This section is intended to introduce the reader to various aspects of art that may be related to various aspects of the present invention, and is believed to provide the reader with useful background information to facilitate a better understanding of the various aspects of the present invention. Accordingly, it should be understood that the description in this section is for purposes of illustration and is not an admission of prior art.
The special network device based on the LTE technology is usually transplanted on the basis of a public network device, and is developed according to specific requirements, and software protocol stacks of the terminal and the base station are also consistent with the 3GPP standard. However, since the band information of the dedicated network terminal is not consistent with the band information of the public network terminal, the band information verification process of the dedicated network terminal is omitted in the transplanting process, and the band information used by the non-dedicated network is stored in the terminal. In the process that the terminal accesses the network, the base station does not verify the band information of the UE (user terminal), the terminal storing the non-private network band information is allowed to access the private network, and the terminal reports the non-private network band information. The base station prepares to configure the pilot frequency point information of the adjacent cell to the terminal according to an A2 event (the signal intensity of a serving cell is lower than a set threshold) reported by the terminal, but the base station verifies that the band information reported by the terminal is inconsistent with the band information in the adjacent cell, so that the base station does not configure the pilot frequency point information to the terminal, the terminal cannot measure the specified pilot frequency point, and the terminal is far away from the serving cell, thereby finally causing the bad consequence of terminal offline.
At present, according to 3GPP protocols 36.331 and 36.304, after reading SIB1 and obtaining band information of a cell, a terminal may camp on a correct cell through frequency sweeping or stored frequency point information. In the following terminal access process, the UE capability information reported by the UE has band information, the base station only stores the band information, and does not check the band information and the band information in the pilot frequency point information on the base station, so that the terminal can initiate an RA and complete access. When the terminal meets the A2 event (triggering start of pilot frequency measurement), the base station issues to the terminal according to the configured pilot frequency point information, and the terminal is enabled to measure the pilot frequency point of the neighboring cell configured by the base station, but since the base station checks the band in the UE capability information report and the band of the pilot frequency point configured by the base station at the moment, the check is not performed due to the inconsistency of the two band information, and finally the base station does not configure the pilot frequency point information of the neighboring cell to the terminal, and the terminal cannot know the frequency point information to be measured.
