M2M Terminal Group Network Access via Representative Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The large number of Machine to Machine (M2M) terminals accessing a cellular communication network simultaneously causes network access congestion, as existing systems are not equipped to handle such a high volume of connections simultaneously.
Innovation Solution
A network access method and apparatus where M2M terminals determine an access resource based on their group identifier, allowing at least one terminal to conduct network access on behalf of the group, thereby reducing the individual load and preventing congestion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If individual M2M terminals access the network separately, then each terminal can establish its own connection, but the base station becomes overwhelmed and network access congestion occurs
Solution Approach 1:
Multiple M2M terminals are merged into a single M2M terminal group, which then accesses the network as one unified entity. The group is represented by a specific M2M terminal that handles all network access procedures on behalf of the entire group, thereby consolidating multiple individual access attempts into a single collective access operation.
Solution Approach 2:
The M2M terminal group acts as an intermediary between individual M2M terminals and the base station. Instead of individual terminals directly communicating with the base station, the group representative serves as the intermediary that manages network access for all members, reducing the direct burden on the base station.
2Quantity of substance
If numerous M2M terminals access simultaneously, then comprehensive network coverage is achieved, but the access resource demand exceeds base station capacity
Solution Approach 1:
The large population of M2M terminals is segmented into multiple smaller M2M terminal groups. Each group is assigned dedicated access resources and is represented by a specific terminal, thereby dividing the overwhelming number of individual access requests into manageable group-level requests that the base station can handle efficiently.
Solution Approach 2:
The M2M terminal group representative performs multiple functions: it represents all members of the group for network access, manages resource allocation for the group, and communicates with the base station on behalf of all group members. This multi-functionality reduces the overall complexity by consolidating multiple individual terminal functions into a single representative entity.

AI summary
A network access method and an apparatus are provided. The Machine to Machine (M2M) terminal in one M2M terminal group determines an access resource according to an identifier of the M2M terminal group which the M2M terminal is a member of, and The M2M terminal of the M2M terminal group uses the determined access resource to conduct network access on behalf of the M2M terminal group. The method and apparatus can ensure that numerous M2M terminals can successfully access the network at the same time.
