Pseudo-random cell reselection
View Patent ↗An apparatus comprising a processor configured to initiate re-selection and/or re-registration procedures and, responsive to a first parameter, delay initiation of re-selection and/or re-registration procedures for a random and/or pseudo-random delay value.
1. An apparatus comprising:
a memory configured to store one or more parameter values;
a processor configured to at least:
initiate at least one of a cell re-selection procedure and a cell re-registration procedure;
delay, responsive to a first parameter, initiation of at least one of the cell re-selection procedure and the cell re-registration procedure, wherein the delay comprises at least one of a random delay value and a pseudo-random delay value, wherein the first parameter comprises a maximum delay value and an indicator to delay initiation of the at least one of the cell-reselection procedure and the cell re-registration procedure, wherein at least one of the random delay value and the pseudo-random delay value is less than or equal to the maximum delay value; and
generate at least one of the random delay value and the pseudo-random delay value responsive to the apparatus at least one of deciding to reselect to a new cell and receiving a message requesting re-registration.
2. The apparatus as claimed in claim 1 , wherein the memory is further configured to store the first parameter.
3. The apparatus as claimed in claim 1 , wherein the indicator comprises a distribution flag having a value of true.
4. The apparatus as claimed in claim 1 , further comprising a communications interface configured to send a message relating to at least one of the cell re-selection procedure and the cell re-registration procedure.
5. The apparatus as claimed in claim 4 , wherein the message is at least one of:
a re-registration message;
a cell update message; and
a location update message.
6. The apparatus of claim 1 , wherein the apparatus is configured to receive the first parameter from another device.
7. The apparatus as claimed in claim 1 , wherein the other device comprises an access node comprising at least one of:
a node B;
an enhanced node B;
a base station;
a local node B; and
a wireless communication access point.
8. The apparatus as claimed in claim 1 , wherein the apparatus is comprised in a user equipment.
9. A method comprising:
initiating at least one of a cell re-selection procedure and a cell re-registration procedure, using a processor;
delaying, responsive to a first parameter, initiating at least one of the cell re-selection procedure and the cell re-registration procedure, wherein the delay comprises at least one of a random delay value and a pseudo-random delay value, wherein the first parameter comprises a maximum delay value and an indicator to delay initiation of the at least one of the cell-reselection procedure and the cell re-registration procedure, wherein at least one of the random delay value and the pseudo-random delay value is less than or equal to the maximum delay value; and
generating at least one of the random and the pseudo-random delay value responsive to at least one of deciding to reselect to a new cell and receiving a message requesting re-registration.
10. The method as claimed in claim 9 , further comprising storing the first parameter.
11. The method as claimed in claim 9 , wherein the indicator comprises a distribution flag having a value of true.
12. The method as claimed in claim 9 , further comprising sending a message relating to at least one of the cell re-selection procedure and the cell re-registration procedure.
13. The method as claimed in claim 12 , wherein the message is at least one of:
a re-registration message;
a cell update message; and
a location update message.
14. The method as claimed in claim 9 , further comprising receiving the first parameter from another device.
15. The method as claimed in claim 9 , wherein the other device further apparatus comprises an access node comprising at least one of:
a node B;
an enhanced node B;
a base station;
a local node B; and
a wireless communication access point.
16. A non-transitory computer-readable medium encoded with instructions that, when executed by a computer, perform at least the following:
initiate at least one of a cell re-selection procedure and a cell re-registration procedure;
delay, responsive to a first parameter, initiating at least one of the cell re-selection procedure and the cell re-registration procedure, wherein the delay comprises at least one of a random delay value and a pseudo-random delay value, wherein the first parameter comprises a maximum delay value and an indicator to delay initiation of at least one of the cell-reselection procedure and the cell re-registration procedure, wherein at least one of the random delay value and the pseudo-random delay value is less than or equal to the maximum delay value; and
generating at least one of the random and the pseudo-random delay value responsive to at least one of deciding to reselect to a new cell and receiving a message requesting re-registration.
17. The non-transitory computer-readable medium as claimed in claim 16 , further performing storing the first parameter.
18. The non-transitory computer-readable medium as claimed in claim 16 , wherein the indicator comprises a distribution flag having a value of true.
19. The non-transitory computer-readable medium as claimed in claim 16 , further performing generating the random delay value and the pseudo-random delay value.
20. The non-transitory computer-readable medium as claimed in claim 16 , further performing sending a message relating to at least one of the cell re-selection procedure and the cell re-registration procedure.
21. The apparatus as claimed in claim 1 , wherein the first parameter is received in a broadcast message.
