Embodiment 1

[0036] refer to figure 1 , which shows a flow chart of a method for accessing a machine type communication terminal in this embodiment, and this embodiment may specifically include the following steps:

[0037] S101, the machine type communication MTC terminal sends a random access message 1 to the base station;

[0038] In this embodiment, the MTC terminals are grouped, each group of MTC terminals is assigned a Group ID, and each corresponding MTC terminal in each group is assigned a Group ID and MTC UE ID, wherein the Group ID is a group ID, and the same group ID Indicates that the MTC device belongs to a group, and the MTC UEID is the ID of each MTC terminal in the group to which it belongs. The ID of each UE in the group is unique and allocated in advance, so no conflicts will occur.

[0039] In this embodiment, the random access message 1 includes the random access preamble sequence Preamble, and the random access preamble sequence Preamble is selected by the MTC termina...

Embodiment 2

[0062] In this embodiment, on the basis of Embodiment 1, the reception of the random access response message 2 and the conflict resolution message 4 by the MTC terminal is described in detail. figure 2 It is a flowchart of a method for accessing a machine type communication terminal in this embodiment, and this embodiment may specifically include the following steps:

[0063] S201, the machine type communication MTC terminal sends a random access message 1 to the base station, the random access message 1 includes a random access preamble sequence Preamble, and the random access preamble sequence Preamble is selected by the MTC terminal from the random access preamble sequences of the group to which it belongs get;

[0064] S202, the MTC terminal receives the random access response message 2 sent by the base station, the random access response message 2 includes random access responses corresponding to multiple groups of MTC terminals, and the random access response correspond...

Embodiment 3

[0140] This embodiment combines Figure 7 To illustrate the interaction process between the terminal and the base station. refer to Figure 7 is a flow chart of an interaction process between a terminal and a base station in this embodiment, wherein UE represents a terminal, and eNB is an abbreviation of eNodeB, referring to a base station.

[0141] The interaction between the terminal and the base station during the random access process includes several processes of MSG1, MSG2, MSG3, and MSG4, as follows:

[0142] MSG1, the terminal sends a random access message 1 to the base station;

[0143] The above random access message 1 includes a random access preamble sequence Preamble, and the above random access preamble sequence Preamble is selected by the MTC terminal from the random access preamble sequences of the group to which it belongs;

[0144] MSG2, the terminal receives the random access response message 2 sent by the base station;

[0145] The above random access r...

Abstract

The invention provides a machine-type communication terminal, an access method for the same and a base station. The problem that large quantities of MTC (machine-type communication) terminals randomly access a base station to cause excessively heavy signal load on the base station is solved. The access method for the machine-type communication (MTC) terminal includes that the machine-type communication (MTC) terminal transmits random access information I to the base station; the MTC terminal receives random access response information 2 which is generated according to the random access information 1 and is transmitted by the base station; the MTC terminal transmits random access information 3 to the base station when corresponding random access response in the random access response information 2 is matched with the MTC terminal; and the MTC terminal receives conflict resolution information 4 which is transmitted by the base station and corresponds to ID (identification) of a group containing the MTC terminal in the random access information 3, and whether the MTC terminal can access to the base station or not is determined according to information which is contained in the conflict resolution information 4 and is used for indicating access-granted MTC terminals in the group. The machine-type communication terminal, the access method and the base station have the advantages that network load is obviously reduced, and network congestion is avoided.

Description

technical field [0001] The invention relates to the technical field of testing, in particular to a method for accessing a machine type communication terminal, a base station, and a terminal. Background technique [0002] With the development of communication technology, Machine-Type Communication (MTC, Machine-Type Communication) technology has received extensive attention. MTC communication technology integrates data acquisition, remote monitoring, telecommunications and information technology to automate business processes, integrate real-time status of company information technology (IT) systems and non-IT equipment, and create value-added services. In an MTC communication system, a terminal device is called an MTC terminal. [0003] With the continuous maturity of the MTC communication technology, a large number of MTC terminals will be added to the MTC communication system. If the access operation of the MTC terminals is not optimized, the performance of the wireless n...
