Communication method and system for machine-type communication UE
First Claim
1. A communication method for a Machine-Type Communication (MTC) User Equipment (UE), comprising:
- at least one MTC UE in an MTC UE group receiving broadcast information carrying group trigger information from an MTC server based on group paging information received, wherein the group trigger information is used for triggering the at least one MTC UE in the MTC UE group; and
the at least one MTC UE communicating with the MTC server based on the group trigger information;
wherein the at least one MTC UE in the MTC UE group receiving the broadcast information carrying the group trigger information from the MTC server comprises;
the at least one MTC UE determining that the group paging information is received by itself, wherein the group paging information is used for indicating change of the broadcast information;
the at least one MTC UE detecting, based on the group paging information, whether the group trigger information carried in the broadcast information is the one needed by itself;
if so, the at least one MTC UE acquiring the group trigger information from the broadcast information;
if not, the at least one MTC UE discarding the group trigger information.

Abstract
A communication method and system for a Machine-Type Communication (MTC) User Equipment (UE) are disclosed. The method includes that: at least one MTC UE in an MTC UE group receives, based on group paging information received, broadcast information carrying group trigger information from an MTC server, wherein the group trigger information is used for triggering the at least one MTC UE in the MTC UE group; and the at least one UE communicates with the MTC server based on the group trigger information. In the disclosure, the group trigger information is broadcast to the MTC UE group through the broadcast information, so that a plurality of MTC UE in one group is triggered simultaneously, thus optimizing group triggering process, and reducing network resources occupied in the group triggering process.

13. A Machine-Type Communication (MTC) User Equipment (UE), comprising:
-
a receiving entity configured to receive, based on group paging information received, broadcast information carrying group trigger information from an MTC server, wherein the group trigger information is used for triggering the MTC UE in the MTC UE group; and a communication entity configured to communicate with the MTC server based on the group trigger information; wherein the receiving entity comprises; a determining unit configured to determine that the group paging information is received by itself, wherein the group paging information is used for indicating change of the broadcast information; a detecting unit configured to detect, based on the group paging information, whether the group trigger information carried in the broadcast information is the one needed by itself; an acquiring unit configured to acquire the group trigger information from the broadcast information based on a condition that a detecting result is positive; and a discarding unit configured to discard the group trigger information based on a condition that the detecting result is negative. - View Dependent Claims (14)

15. A communication system for a Machine-Type Communication (MTC) User Equipment (UE), comprising:
- an MTC server, an MTC-Interworking Function (MTC-IWF), a Packet Data Network Gateway (PGW)/Gateway General Packet Radio Service Support Node (GGSN), an MTC UE group, a service node of the MTC UE group and a piece of access network equipment, wherein
the MTC server is configured to generate group trigger information; the MTC-IWF is configured to send the group trigger information through a T4 interface or a T5 interface or a Cell Broadcast Centre (CBC) or a Broadcast Multicast Service Centre (BMSC); the PGW/GGSN is configured to send the group trigger information through a user plane; the service node of the MTC UE group is configured to send group paging information to the MTC UE group, and send the group trigger information to the access network equipment; the MTC UE in the MTC UE group comprises; a receiving entity configured to receive, based on the group paging information received, broadcast information carrying the group trigger information from the MTC server, wherein the group trigger information is used for triggering the MTC UE in the MTC UE group; and a communication entity configured to communicate with the MTC server based on the group trigger information; wherein at least one MTC UE in the MTC UE group is configured to perform the following operation; the at least one MTC UE determining that the group paging information is received by itself, wherein the group paging information is used for indicating change of the broadcast information; the at least one MTC UE detecting, based on the group paging information, whether the group trigger information carried in the broadcast information is the one needed by itself; if so, the at least one MTC UE acquiring the group trigger information from the broadcast information; if not, the at least one MTC UE discarding the group trigger information.
- an MTC server, an MTC-Interworking Function (MTC-IWF), a Packet Data Network Gateway (PGW)/Gateway General Packet Radio Service Support Node (GGSN), an MTC UE group, a service node of the MTC UE group and a piece of access network equipment, wherein
