| 摘要 |
The invention relates to a method for enhancing machine type communication between a mobile communication network on the one hand, and a plurality of machine type communication devices on the other hand, wherein the mobile communication network comprises at least one base station entity, wherein – at least temporarily – a radio connection between each of the machine type communication devices and the base station entity is established via a radio interface of the machine type communication devices, respectively, to the mobile communication network, wherein the plurality of machine type communication devices comprises at least a first machine type communication device, and – besides the first machine type communication device – at least one further machine type communication device, wherein the first machine type communication device and the at least one further machine type communication device both comprise – besides the radio interface to the mobile communication network – a further radio interface, respectively, wherein the further radio interface of the first machine type communication device and the further radio interface of the at least one further machine type communication device provide a communication link between the first machine type communication device and the at least one further machine type communication device, wherein the method comprises the following steps in case that the radio connection between the at least one further machine type communication device and the base station entity is functional, while the radio connection between the first machine type communication device and the base station entity being dysfunctional: -- transmitting, in a first step, an emergency mode message from the base station entity to the at least one further machine type communication device, the emergency mode message comprising a transmission command to retrieve machine type communication data from the first machine type communication device, -- transmitting, in a second step subsequent to the first step, a request from the at least one further machine type communication device to the first machine type communicationdevice to transmit machine type communication data to the at least one further machine type communication device, -- transmitting, in a third step subsequent to the second step, the machine type communication data from the first machine type communication device to the at least one further machine type communication device according to the transmission command, -- transmitting, in a fourth step subsequent to the third step, the machine type communication data from the at least one further machine type communication device to the base station entity. |
