1. A method for organizing random access (RA) resources, the method comprising:
- forming a device group including a plurality of group members and at least one group representative;
providing the at least one group representative with priority access to RA resources;
sending, by the at least one group representative, a primary event message to a central unit in the RA resources;
sending, by the central unit, a response message, responsive to the primary event message, to the group members for managing access of the group members to the RA resources; and
wherein at least one RA preamble sequence is reserved for the at least one group representative.

Abstract
A method for organizing random access (RA) resources, comprising: forming a device group including a plurality of group members and at least one group representative; providing the at least one group representative with priority access to RA resources; sending, by the at least one group representative, a primary event message to a central unit in said RA resources; and sending, by the central unit, a response message, responsive to the primary event message, to the group members for managing access of the group members to the RA resources.

-
forming a device group including a plurality of group members and at least one group representative; providing the at least one group representative with priority access to RA resources; sending, by the at least one group representative, a primary event message to a central unit in the RA resources; sending, by the central unit, a response message, responsive to the primary event message, to the group members for managing access of the group members to the RA resources; wherein; the response message includes the primary event message; and requesting access to the RA resources for sending a secondary event message is stopped by a group member if the secondary event message corresponds to the primary event message. - View Dependent Claims (5, 6)

-
forming a device group including a plurality of group members and at least one group representative; providing the at least one group representative with priority access to RA resources; sending, by the at least one group representative, a primary event message to a central unit in the RA resources; sending, by the central unit, a response message, responsive to the primary event message, to the group members for managing access of the group members to the RA resources; wherein; at least one secondary event message from at least one group member is detected by the at least one group representative, and the at least one secondary event message is attached by the at least one group representative to the primary event message; the response message includes the primary event message and the at least one secondary event message; and requesting access to the RA resources for sending a secondary event message is stopped by a group member, if its secondary event message is included in the response message. - View Dependent Claims (8, 9)

10. A method for organizing random access (RA) resources, the method comprising:
-
forming a device group including a plurality of group members and at least one group representative; providing the at least one group representative with priority access to RA resources; sending, by the at least one group representative, a primary event message to a central unit in the RA resources; sending, by the central unit, a response message, responsive to the primary event message, to the group members for managing access of the group members to the RA resources; wherein the response message includes scheduling information for scheduling at least one selected group member for access to the RA resources; wherein the scheduling information includes priority information for providing multiple selected group members with a priority for access to the RA resources; and wherein each group member determines whether it is a selected group member, and the RA resources are accessed by each group member according to the priority information.

12. A system for organizing random access (RA) resources, the system comprising:
-
at least one device group including a plurality of group members and at least one group representative, wherein the at least one group representative is provided with priority access to RA resources and is configured to send a primary event message to the central unit in the RA resources; a central unit configured to send, responsive to the primary event message, a response message to the group members for managing access of the group members to the RA resources; and wherein at least one RA preamble sequence is reserved for the at least one group representative.

13. A central unit for organizing random access (RA) resources, the central unit comprising:
-
a controller for providing at least one group representative of at least one device group with priority access to RA resources for sending a primary event message to the central unit, the at least one device group including the at least one group representative and a plurality of group members; a receiver for receiving the primary event message from the at least one group representative; a transmitter for sending, responsive to the primary event message, a response message to the group members for managing access of the group members to the RA resources; and wherein at least one RA preamble sequence is reserved for the at least one group representative.
