Embodiment Construction

[0022] The present invention aims to provide a method and system for realizing terminal access by using the public long code mask allocated by the base station, so as to realize the successful access of the terminal under the condition that the PLCM allocated to the terminal is unique in the same network segment .

[0023] Among them, the PLCM is 42 bits. The 3GPP2 C.S0072 protocol stipulates that in the case of allocation by the base station, the first 5 bits are fixed at 10100, and the rest is generated by a specific algorithm of the base station. In the present invention, various system information is used to generate PLCM, so as to ensure that it is unique in the network segment (the constitution of PLCM according to the embodiment of the present invention is as follows figure 2 shown).

[0024] Among them, the uniqueness of PLCM is guaranteed by the following characteristics of each component element: a) Mobile Switching Center (MSC) serial number distinguishes differen...

Abstract

The invention discloses a terminal access method and a corresponding system, wherein, the method includes the following steps: a terminal sends an access request message to a base station; once the base station judges that the base station supporting the terminal distributes a public long code and mask (PLCM) to the terminal according to the access request message, the base station generates the PLCM distributed to the terminal; the base station utilizes the PLCM to establish a traffic channel with the terminal and informs the terminal of the PLCM; and the terminal utilizes the PLCM to get access to the base station through the traffic channel. By the invention, the terminal supporting the mobile terminal identification can get access to the base station, thus being capable of avoiding the impact on the core network which is caused by that the terminal is identified by the mobile terminal identification.

Description

technical field [0001] The present invention relates to the field of communications, and more particularly to a terminal access method and system. Background technique [0002] In 2006, electronic serial number (Electronic Serial Number, ESN for short) resources of mobile terminals began to be in short supply. Many equipment manufacturers and operators are aware of this problem and need to find a new way to identify mobile terminals. Mobile Station Equipment Identifier (MEID for short) is a new identification method proposed by Code Division Multiple Access (CDMA) 2000 Release D. At present, all equipment manufacturers tend to use this identification instead of ESN. [0003] Pseudo ESN (pESN) is a 32-bit mobile terminal identifier generated from a 56-bit MEID through a specific algorithm, which can solve the problem of exhaustion of the original ESN. The manufacturer code (high 8 bits) of pESN is fixed at 0x80, and the low 24 bits use 56 bits Calculated by the SHA-1 hash al...
