摘要

The present invention provides a method for adding a secondary serving cell, an apparatus, a device, and a network system. The method includes: communicating, with each other to acquire a unified serial number of a random access preamble code, a unified serial number of a PRACH mask code, and a unified cell radio network temporary identifier of a terminal; scrambling the serial number of the random access preamble code and the serial number of the PRACH mask code, and then sending the serial number of the random access preamble code and the serial number of the PRACH mask code to the terminal; and determining, a time advance command TAC according to a random access request message that carries the random access preamble code, and sending the TAC to the terminal.

說明書

According to the method for adding a secondary serving cell, the apparatus, the device, and the network system that are provided in the embodiments of the present invention, a secondary base station sends a secondary serving cell addition response message to a primary base station, so that after the primary base station sends a reconfiguration message to a terminal, it is ensured that the secondary base station can correctly receive a random access request message sent by the terminal, and the secondary base station then can determine, according to the random access request message, content of a random access response message and a time for sending the message to the terminal. According to the embodiments of the present invention, a primary serving cell and a secondary serving cell can still work properly in a case in which the primary serving cell and the secondary serving cell belong to different base stations, or when a delay over a connection between the primary serving cell and the secondary serving cell is relatively long and a capacity is relatively small.
