Abstract

Method, apparatus, and computer program product example embodiments enable access to a wireless communications medium. In example embodiments, a method comprises receiving, by an apparatus, one or more wireless communications message frames including at least a dedicated a network type identifier that identifies an associated network type comprising at least one of a synchronized contention group and an isolated contention group; and determining, by the apparatus, the network type of a wireless communications network associated with the one or more wireless communication message frames, based on the received network type identifier.

Claims

1. A method, comprising:

receiving, by an apparatus, one or more wireless communications message frames including at least a dedicated a network type identifier that identifies an associated network type comprising at least one of a synchronized contention group and an isolated contention group; and

determining, by the apparatus, the network type of a wireless communications network associated with the one or more wireless communication message frames, based on the received network type identifier.

2. The method of claim 1, further comprising:

wherein the determined network type of the wireless communications network comprises a synchronized contention group and the apparatus currently operates in an existing contention group of the wireless communications network;

determining, by the apparatus, that the received one or more wireless communications message frames is from a foreign contention group in the wireless communications network and that the one or more wireless communications message frames include a received time value different from a local time value in the apparatus; and

deciding, by the apparatus, to adopt the discovery window schedule of the foreign contention group based on the received time value.

3. The method of claim 2, further comprising:

transmitting, by the apparatus, one or more synchronization frames to the existing contention group, when the apparatus moves its operations to the foreign contention group, the one or more synchronization frames including information about the foreign contention group, to enable wireless devices in the existing contention group to adopt the discovery window schedule of the foreign contention group.

4. The method of claim 2, wherein when the received time value is larger than the local time value, the discovery window schedule of the foreign contention group is adopted.

5. The method of claim 1, further comprising:

wherein the determined network type of the wireless communications network comprises an isolated contention group and the apparatus currently operates in an existing contention group of the wireless communications network;

determining, by the apparatus, that the received one or more wireless communications message frames is from a foreign contention group in the wireless communications network and that the one or more wireless communications message frames include a received time value different from a local time value in the apparatus; and

deciding, by the apparatus, to adopt the discovery window schedule of the foreign contention group based on the received time value.

6. The method of claim 5, further comprising:

ceasing, by the apparatus, operations in the existing contention group of which it has been a member, and immediately starting operations in the foreign contention group when the apparatus is moving its operations to the foreign contention group.

7. A method, comprising:

executing, by an apparatus, a programmed application that determines a network type for a wireless communications network associated with the apparatus, based on an active requirement associated with the apparatus; and

commanding, by the apparatus, a protocol stack in the apparatus, to operate the wireless communications network comprising at least one of a synchronized contention group and an isolated contention group, in response to the determined network type.

8. An apparatus, comprising:

at least one processor;

at least one memory including computer program code;

the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus at least to;

receive one or more wireless communications message frames including at least a dedicated a network type identifier that identifies an associated network type comprising at least one of a synchronized contention group and an isolated contention group; and

determine the network type of a wireless communications network associated with the one or more wireless communication message frames, based on the received network type identifier.

9. The apparatus of claim 8, further comprising:

wherein the determined network type of the wireless communications network comprises a synchronized contention group and the apparatus currently operates in an existing contention group of the wireless communications network;

the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus at least to;

determine that the received one or more wireless communications message frames is from a foreign contention group in the wireless communications network and that the one or more wireless communications message frames include a received time value different from a local time value in the apparatus; and

decide to adopt the discovery window schedule of the foreign contention group based on the received time value.

10. The apparatus of claim 9, further comprising:

the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus at least to;

transmit one or more synchronization frames to the existing contention group, when the apparatus moves its operations to the foreign contention group, the one or more synchronization frames including information about the foreign contention group, to enable wireless devices in the existing contention group to adopt the discovery window schedule of the foreign contention group.

11. The apparatus of claim 9, wherein when the received time value is larger than the local time value, the discovery window schedule of the foreign contention group is adopted.

12. The apparatus of claim 8, further comprising:

wherein the determined network type of the wireless communications network comprises an isolated contention group and the apparatus currently operates in an existing contention group of the wireless communications network;

the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus at least to;

determine that the received one or more wireless communications message frames is from a foreign contention group in the wireless communications network and that the one or more wireless communications message frames include a received time value different from a local time value in the apparatus; and

decide to adopt the discovery window schedule of the foreign contention group based on the received time value.

13. The apparatus of claim 12, further comprising:

the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus at least to;

cease operations in the existing contention group of which it has been a member, and immediately starting operations in the foreign contention group when the apparatus is moving its operations to the foreign contention group.

14. An apparatus, comprising:

at least one processor;

at least one memory including computer program code;

the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus at least to;

execute a programmed application that determines a network type for a wireless communications network associated with the apparatus, based on an active requirement associated with the apparatus; and
