Methods for enhancing paging operations, related wireless devices and related network nodes
A method performed in a wireless device, for enhancing paging operations with a network node is disclosed. The method comprises determining a group identifier based on a paging occurrence parameter, wherein the group identifier is indicative of a subset of wireless devices belonging to a paging group paged at a same paging occasion.
1. A method, performed in a wireless device, for enhancing paging operations with an associated network node, the method comprising:
determining, based on a paging occurrence parameter representative of a paging probability associated with the wireless device, a group identifier, wherein the group identifier is indicative of a subset of wireless devices belonging to a same paging group to be paged at a same paging occasion.
2. The method according to claim 1 , wherein the paging occurrence parameter is indicative of a paging occurrence frequency associated with the wireless device.
3. The method according to claim 1 , wherein the paging occurrence parameter is further representative of how often the wireless device is paged by the associated network node based on actual paging occurrences and/or estimated paging occurrences.
4. The method according to claim 1 , wherein the determining, based on the paging occurrence parameter, the group identifier comprises determining the paging occurrence parameter based on a number of paging occurrences during a time window.
5. The method according to claim 4 , wherein the determining the paging occurrence parameter based on a number of paging occurrences during the time window comprises analyzing data traffic pattern between the wireless device and the associated network node during the time window, and estimating the number of paging occurrences based on the analysis.
6. The method according to claim 5 , wherein the analyzing the data traffic pattern between the wireless device and the associated network node comprises identifying a paging pattern of the wireless device based on a data traffic parameter indicative of the data traffic pattern between the wireless device and the associated network node.
7. The method according to claim 4 , wherein the determining the paging occurrence parameter based on a number of paging occurrences during a time window comprises determining the number of actual paging occurrences during the time window.
8. The method according to claim 1 , wherein the determining, based on the paging occurrence parameter, the group identifier comprises determining the group identifier based on an overhearing parameter.
9. The method according to claim 1 , further comprising:
transmitting a group change request to the associated network node, the group change request comprising the determined group identifier.
10. The method according to claim 1 , further comprising:
proceeding with monitoring the paging occasion when the determined group identifier is received from the associated network node.
11. A method, performed in a network node, for enhancing paging operations with an associated wireless device, the method comprising:
determining, based on a paging occurrence parameter of the associated wireless device determined based on a paging probability associated with the associated wireless device over a time window, a group identifier of the associated wireless device, wherein the group identifier is indicative of a subset of associated wireless devices belonging to a same paging group to be paged at a same paging occasion; and
assigning the group identifier to the associated wireless device.
12. The method according to claim 11 , the method comprising: transmitting the group identifier and/or the paging occurrence parameter to the associated wireless device.
13. The method according to claim 11 , wherein determining, based on the paging occurrence parameter, the group identifier comprises determining, based on a group parameter indicative of a group size, the group identifier.
14. The method according to claim 11 , wherein determining, based on the paging occurrence parameter of the associated wireless device, the group identifier of the associated wireless device comprises determining the paging occurrence parameter based on a number of paging occurrences of the associated wireless device during a time window.
15. The method according to claim 14 , wherein determining the paging occurrence parameter of the associated wireless device based on a number of paging occurrences of the associated wireless device during the time window comprises analyzing data traffic between the associated wireless device and the network node during the time window, and estimating the number of paging occurrences based on the analysis.
16. The method according to claim 15 , wherein analyzing the data traffic between the associated wireless device and the network node comprises identifying a paging pattern of the associated wireless device based on one or more of a data traffic parameter indicative of the data traffic between the associated wireless device and the network node.
17. The method according to claim 14 , wherein determining the paging occurrence parameter based on a number of paging occurrences during a time window comprises determining the number of actual paging occurrences during the time window.
18. The method according to claim 11 , wherein determining, based on the paging occurrence parameter, the group identifier comprises calculating the paging occurrence parameter based on the number of actual paging occurrences during the time window and the estimated number of paging occurrences.
19. The method according to claim 11 , wherein the group identifier is arranged according to the paging occurrence parameter of the associated wireless device.
