Abstract

The embodiments herein relate to a method in a transceiver (110) for permitting access to a cellular communications system (100). The transceiver (110) is configured to transmit traffic to a communication node (101,120). The transceiver (110) receives a permission message from the communication node (101,120). The permission message indicates permission to a group of transceivers to transmit an access request message indicating a request to transmit the traffic to the communication node (101, 120). The transceiver (110) determines whether the transceiver (110) is comprised in the group of transceivers having permission to transmit the access request message based on the received permission message.

Claims

1. A method in a transceiver for permitting access to a cellular communications system, the transceiver is configured to transmit machine to machine traffic to a communication node, the method comprising:

receiving a permission message from the communication node, said permission message indicates permission to a group of transceivers to transmit an access request message, said message indicating a request to transmit the machine to machine traffic to the communication node, and wherein the permission message is based on a current congestion situation in the cellular communications system; and

determining whether the transceiver is comprised in the group of transceivers having permission to transmit the access request message based on the received permission message,

wherein each transceiver in the cellular communications system is associated with an identity and the group of transceivers is associated with a range of transceiver identifiers, and

wherein the permission message indicates the range of transceiver identifiers by establishing a start number and end number such that a number between the start number and the end number identifies a transceiver included in the group of transceivers, the number corresponding to the digits comprised within a predetermined portion of a transceiver identifier and the predetermined portion comprising fewer digits than the transceiver identifier.

2. The method according to claim 1, further comprising:

transmitting the access request message to the communication node.

3. The method according to claim 1, further comprising:

determining a priority of the machine to machine traffic.

4. The method according to claim 3, wherein the determining a priority of the machine to machine traffic further comprising:

determining that the machine to machine traffic to the communication node has low priority; and

wherein the method further comprising;

transmitting the access request message indicating request to transmit low priority machine to machine traffic to the communication node based on the received permission message.

5. The method according to the claim 3, wherein the determining a priority of the machine to machine traffic further comprising:

determining that the machine to machine traffic to the communication node has high priority; and

wherein the method further comprising;

transmitting the access request message indicating a request to transmit high priority machine to machine traffic to the communication node independent of the received permission message.

6. The method according to claim 1, further comprising:

identifying a period of time in the permission message, during which period of time the permission message is valid.

7. The method according to claim 1, wherein the transceiver is a user equipment or a mobile station, and wherein the communication node is a evolved Node B, referred to as eNodeB, or a mobility management entity, referred to as MME.

8. The method according to claim 1, wherein the transceiver is a user equipment or a mobile station and the communication node is a UTRAN Node B or a Serving GPRS Support Node, referred to as SGSN, or wherein the transceiver is a user equipment or a mobile station and the communication node is a GERAN base station controller, referred to as BSC or a Serving GPRS Support Node, referred to as SGSN.

9. The method according to any of the claim 1, wherein the permission message is received before the access request message is transmitted.

10. The method according to claim 1, wherein the permission message comprises a validity time during which the transceiver is permitted to transmit access request messages.

11. The method according to claim 1, wherein the identity is based on at least one of an international mobile subscriber identity, an international mobile equipment identity, a telephone number or an in the transceiver configured group identity.

12. A method in a communication node for permitting access to a cellular communication system, the communication node is configured to receive machine to machine traffic from a transceiver, the method comprising:

transmitting a permission message to the transceiver, said permission message indicates permission to a group of transceivers to transmit an access request message, said message indicating a request to transmit the machine to machine traffic to the communication node,

wherein the permission to transmit the access request message is based on available capacity in the cellular communications system,

wherein each transceiver in the cellular communications system is associated with an identity and the group of transceivers is associated with a range of transceiver identifiers, and

wherein the permission message indicates the range of transceiver identifiers by establishing a start number and end number such that a number between the start number and the end number identifies a transceiver included in the group of transceivers, the number corresponding to the digits comprised within a predetermined portion of a transceiver identifier and the predetermined portion comprising fewer digits than the transceiver identifier.

13. A transceiver for permitting access to a cellular communication system, the transceiver comprising:

a transmitting unit configured to transmit machine to machine traffic to a communication node;

a receiving unit configured to receive a permission message from the communication node, said permission message indicates permission to a group of transceivers to transmit an access request message, said message indicating a request to transmit the machine to machine traffic to the communication node, and wherein the permission to transmit the access request message is based on available capacity in the cellular communications system; and

a determining unit configured to determine whether the transceiver is comprised in the group of transceivers having permission to transmit the access request message to the communication node based on the received permission message,

wherein each transceiver in the cellular communication system is associated with an identity and the group of transceivers is associated with a range of transceiver identifiers,

wherein the permission message indicates the range of transceiver identifiers by establishing a start number and end number such that a number between the start number and the end number identifies a transceiver included in the group of transceivers, the number corresponding to the digits comprised within a predetermined portion of a transceiver identifier and the predetermined portion comprising fewer digits than the transceiver identifier.

14. A communication node for permitting access to a cellular communication system, the communication node comprising:

a receiving unit configured to receive machine to machine traffic from a transceiver; and

a transmitting unit configured to transmit a permission message to the transceiver, said permission message indicates permission to a group of transceivers to transmit an access request message, said message indicating a request to transmit the machine to machine traffic to the communication node,

wherein the permission to transmit the access request message is based on available capacity in the cellular communications system,

wherein each transceiver in the cellular communication system is associated with an identity, and the group of transceivers is associated with a range of transceiver identifiers, and

wherein the permission message indicates the range of transceiver identifiers by establishing a start number and end number such that a number between the start number and the end number identifies a transceiver included in the group of transceivers, the number corresponding to the digits comprised within a predetermined portion of a transceiver identifier and the predetermined portion comprising fewer digits than the transceiver identifier.
