Abstract

A method for machine-type communication between a mobile communication network and a machine-type communication device includes: determining, by the machine-type communication device, a waiting time interval based on identity information and time interval information stored in the machine-type communication type and based on application of a hash function operation applied to the identity information; and requesting, by the machine-type communication device, access to a random access resource of the mobile communication network after the determined waiting time interval has elapsed.

Claims

1. A method for machine-type communication between a mobile communication network and a machine-type communication device, the method comprising:

determining, by the machine-type communication device, a waiting time interval based on identity information and time interval information stored in the machine-type communication device, wherein determining the waiting time interval is further based on application of a hash function operation applied to the identity information; and

requesting, by the machine-type communication device, access to a random access resource of the mobile communication network after the determined waiting time interval has elapsed;

wherein the hash function corresponds to a modulo operation on the numerical value of a number derived from the identity information or to a modulo operation on the digit sum of a number derived from the identity information;

wherein a predetermined divisor value is used in the modulo operation; and

wherein the divisor value used in the modulo operation corresponds to a number of groups to which machine type communication devices are assigned.

2. The method according to claim 1, wherein the determined waiting time interval corresponds to the product of the length of the time interval corresponding to the time interval information and the result of the hash function operation applied to the identity information.

3. The method according to claim 1, wherein the identity information comprises an International Mobile Subscriber identity (IMSI) and/or an International Mobile Equipment Identity (IMET) and/or a Media Access Control (MAC) address.

4. The method according to claim 1, wherein the requesting is further based on a predetermined point in time, wherein the requesting occurs after the determined waiting time interval has elapsed relative to the predetermined point in time.

5. The method according to claim 1, wherein a spreading amongst different Random Access Channel (RACH) preambles is performed by applying a second hash function operating on a modified version of the identity information or on other identity information.

6. The method according to claim 5, wherein the second hash function corresponds to a second modulo operation.

7. A machine-type communication device capable of machine-type communication with a mobile communication network, the machine-type communication device being configured to:

determine a waiting time interval based on identity information and time interval information stored in the machine-type communication device, wherein determining the waiting time interval is further based on application of a hash function operation applied to the identity information; and

request, by the machine-type communication device, access to a random access resource of the mobile communication network after the determined waiting time interval has elapsed;

wherein the hash function corresponds to a modulo operation on the numerical value of a number derived from the identity information or to a modulo operation on the digit sum of a number derived from the identity information;

wherein a predetermined divisor value is used in the modulo operation; and

wherein the divisor value used in the modulo operation corresponds to a number of groups to which machine type communication devices are assigned.

8. The machine-type communication device of claim 7, wherein the determined waiting time interval corresponds to the product of the length of the time interval corresponding to the time interval information and the result of the hash function operation applied to the identity information.

9. The machine-type communication device of claim 7, wherein the identity information comprises an International Mobile Subscriber Identity (IMSI) and/or an International Mobile Equipment Identity (IMEI) and/or a Media Access Control (MAC) address.

10. A non-transitory computer-readable medium having processor-executable instructions stored thereon for machine-type communication between a mobile communication network and a machine-type communication device, the processor-executable instructions comprising instructions for:

determining a waiting time interval based on identity information and time interval information stored in the machine-type communication device, wherein determining the waiting time interval is further based on application of a hash function operation applied to the identity information; and

requesting access to a random access resource of the mobile communication network after the determined waiting time interval has elapsed;

wherein the hash function corresponds to a modulo operation on the numerical value of a number derived from the identity information or to a modulo operation on the digit sum of a number derived from the identity information;

wherein a predetermined divisor value is used in the modulo operation; and

wherein the divisor value used in the modulo operation corresponds to a number of groups to which machine type communication devices are assigned.

11. The non-transitory computer-readable medium according to claim 10, wherein the determined waiting time interval corresponds to the product of the length of the time interval corresponding to the time interval information and the result of the hash function operation applied to the identity information.

12. The non-transitory computer-readable medium according to claim 10, wherein the identity information comprises an International Mobile Subscriber Identity (IMSI) and/or an International Mobile Equipment Identity (IMEI) and/or a Media Access Control (MAC) address.

13. The non-transitory computer-readable medium according to claim 10, wherein the requesting is further based on a predetermined point in time, wherein the requesting occurs after the determined waiting time interval has elapsed relative to the predetermined point in time.

14. The non-transitory computer-readable medium according to claim 10, wherein a spreading amongst different Random Access Channel (RACH) preambles is performed by applying a second hash function operating on a modified version of the identity information or on other identity information.

15. The non-transitory computer-readable medium according to claim 10, wherein the second hash function corresponds to a second modulo operation.

16. A mobile communication network for enhancing machine type communication with a machine type communication device, the machine-type communication device being configured to:

determine a waiting time interval based on identity information and time interval information stored in the machine-type communication device, wherein determining the waiting time interval is further based on application of a hash function operation applied to the identity information; and

request, by the machine-type communication device, access to a random access resource of the mobile communication network after the determined waiting time interval has elapsed;

wherein the hash function corresponds to a modulo operation on the numerical value of a number derived from the identity information or to a modulo operation on the digit sum of a number derived from the identity information;

wherein a predetermined divisor value is used in the modulo operation; and

wherein the divisor value used in the modulo operation corresponds to a number of groups to which machine type communication devices are assigned;

the mobile communication device comprising a transmitting device configured to transmit the time interval information and an information related to the hash function operation.

17. The mobile communication network according to claim 16, wherein the information related to the hash function operation includes a predetermined devisor value used in the module operation.
