Method and apparatus for paging policy adaptation in a wireless network

摘要

Various methods and devices are provided to address the need to mitigate the effects of an overload and/or prevent an overload from cascading. In one method, devices are paged (101) according to a first paging policy regarding paging attempts. It is then determined (102) that a reduced availability condition exists for network equipment supporting the first paging policy. While this reduced availability condition exists, user equipment is paged (103) according to an adapted paging policy which is more limited in paging attempts than the first paging policy.

1. A method for paging policy adaptation, the method comprising:
paging devices according to a first paging policy regarding paging attempts; determining that a reduced availability condition exists for network equipment supporting the first paging policy; paging a UE (user equipment) according to an adapted paging policy while the reduced availability condition exists, wherein the adapted paging policy is more limited in paging attempts than the first paging policy; wherein determining that a reduced availability condition exists for network equipment supporting the first paging policy comprises determining that a network node supporting the first paging policy is overloaded; wherein paging the UE according to an adapted paging policy comprises at least one of
when the UE was last seen at the overloaded network node, making one page attempt to page the UE at the overloaded network node and making no additional attempts to page the UE at any other network nodes orwhen the UE was not last seen at the overloaded network node, making at least one page attempt to page the UE while excepting the overloaded network node from the at least one page attempt.
