Wireless communication paging and registration utilizing multiple types of node identifiers

A first node for wireless communication, comprising:

• a list generator configured to determine a list comprising identifiers of nodes where the first node wishes to be paged, wherein the identifiers comprise at least one first type of identifier and at least one second type of identifier;
• and
• a registration controller configured to provide the list in conjunction with registering the first node,
• wherein the first type of identifier comprises an identifier of an individual node, a cell identifier, or an identifier of a subscriber group,
• wherein the second type of identifier relates to a subscriber group,
• wherein the list generator configured to determine the list is configured to identify at least one node for the list based on how frequently the first node will be paged via the at least one node,
• wherein the registration controller is further configured to receive an indication relating to registration at a second node, and
• wherein the indication indicates that an identifier of the first type and not an identifier of the second type shall be used for the registration.

A first node for wireless communication, comprising:

• means for determining a list comprising identifiers of nodes where the first node wishes to be paged, wherein the identifiers comprise at least one first type of identifier and at least one second type of identifier;
• and
• means for providing the list in conjunction with registering the first node,
• wherein the first type of identifier comprises an identifier of an individual node, a cell identifier, or an identifier of a subscriber group,
• wherein the second type of identifier relates to a subscriber group,
• wherein the means for determining the list is configured to identify at least one node for the list based on how frequently the first node will be paged via the at least one node,
• wherein the means for providing is configured to receive an indication relating to registration at a second node, and
• wherein the indication indicates that an identifier of the first type and not an identifier of the second type shall be used for the registration.

A computer-program product, comprising:

• a non-transitory computer-readable medium comprising code for causing a computer to:
• determine, by a first node, a list comprising identifiers of nodes where the first node wishes to be paged, wherein the identifiers comprise at least one first type of identifier and at least one second type of identifier;
• provide, by the first node, the list in conjunction with registering the first node,
• wherein the first type of identifier comprises an identifier of an individual node, a cell identifier, or an identifier of a subscriber group,
• wherein the second type of identifier relates to a subscriber group, and
• wherein the code for causing the computer to determine the list is configured to identify at least one node for the list based on how frequently the first node will be paged via the at least one node;
• and
• receive, by the first node, an indication relating to registration at a second node, wherein the indication indicates that an identifier of the first type and not an identifier of the second type shall be used for the registration.
