Method and apparatus for paging UE smartly in MME pool
First Claim
1. A method for paging User equipment (UE) smartly in MME pool, comprising:
- transmitting a paging request to a first eNodeB which the UE last accessed;
if no response is received in response to transmitting the paging request to the first eNodeB which the UE last accessed, transmitting the paging request to all eNodeBs belonging to a first Tracking Area to which the first eNodeB belongs;
if no response is received in response to transmitting the paging request to all eNodeBs belonging to the first Tracking Area to which the first eNodeB belongs, determining, in a Tracking Area list assigned to the UE, a first group of Tracking Areas adjacent to the first Tracking Area, and transmitting the paging request to all eNodeBs belonging to the first group of Tracking Areas; and
if no response is received in response to transmitting the paging request to all eNodeBs belonging to the first group of Tracking Areas, determining, in the Tracking Area list, a second group of Tracking Areas which are adjacent to the first group of Tracking Areas except the ones which have been paged, and transmitting the paging request to all eNodeBs belonging to the second group of Tracking Areas.

Abstract
This disclosure provides a method for paging User equipment (UE) smartly in MME pool, comprising: transmitting a paging request to a first eNodeB the UE last accessed; if the UE is not paged, transmitting the paging request to all eNodeBs belonging to a first Tracking Area (TA) to which the first eNodeB belongs; and if the UE is not paged, determining, in a Tracking Area list assigned to the UE, a first group of Tracking Areas (TAs) adjacent to the first Tracking Area, and transmitting the paging request to all eNodeBs belonging to the first group of Tracking Areas. This disclosure also provides an apparatus for paging User equipment (UE) smartly in MME pool. This may largely decrease the paging load and save the radio resources without perceivable paging quality degradation.

16. An apparatus for paging User equipment (UE) smartly in MME pool, comprising:
-
a first module configured to transmit a paging request to a first eNodeB the UE last accessed; a second module configured to transmit the paging request to all eNodeBs belonging to a first Tracking Area (TA) to which the first eNodeB belongs, if no response is received to the paging request to the first eNodeB the UE last accessed; a third module configured to determine, in a Tracking Area list assigned to the UE, a first group of Tracking Areas (TAs) adjacent to the first Tracking Area, and transmit the paging request to all eNodeBs belonging to the first group of Tracking Areas, if no response is received to the paging request to all eNodeBs belonging to the first Tracking Area to which the first eNodeB belongs; and a fourth module configured to, if no response is received to the paging request to all eNodeBs belonging to the first group of Tracking Areas, determine, in the Tracking Area list, a second group of Tracking Areas which are adjacent to the first group of Tracking Areas except the ones which have been paged, and transmit the paging request to all eNodeBs belonging to the second group of Tracking Areas. - View Dependent Claims (17)
