Abstract

In multicarrier networks mobile devices can be distributed amongst carriers based on different criteria. However, prioritization may cause certain devices to end up on a carrier that is not optimal for the network. When there is a deployment of different types of cells (e.g., macro cells, small cells, etc.), the cells can use the same frequency. Consequently, a priority value contained within a system information broadcast message can override the mobile default cell transition procedures and thus select a neighboring cell based on additional criteria. Thus, small cells can be deployed to offload traffic from macro cells in spite of the small cells and macro cells operating in the same frequency band.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . A method, comprising:
 determining, by a user equipment comprising a processor, that inter-frequency cell reselection during idle mode is to be performed by the user equipment; and   reselecting, by the user equipment, a cell from cells based on a function of respective cell priorities of the cells, and respective frequency priorities of frequencies employed by the cells.   
     
     
         2 . The method of  claim 1 , wherein the function is further based on respective signal strengths of the cells. 
     
     
         3 . The method of  claim 1 , wherein the function is further based on respective user equipment priorities of a group of user equipment, comprising the user equipment, operating by using the cells. 
     
     
         4 . The method of  claim 1 , wherein the respective cell priorities are based on respective loads of the cells. 
     
     
         5 . The method of  claim 1 , wherein the respective cell priorities are based on respective bandwidths of the cells. 
     
     
         6 . The method of  claim 1 , wherein the cells comprise a small cell and a macro cell, and the smalls cell has a higher cell priority than the macro cell. 
     
     
         7 . The method of  claim 1 , wherein the function assigns respective weights to the respective cell priorities and the respective frequency priorities. 
     
     
         8 . A mobile device, comprising:
 a processor; and   a memory that stores executable instructions that, when executed by the processor, facilitate performance of operations, comprising:
 determining that inter-frequency cell reselection should be performed during idle mode according to a reselection criterion; and 
 in response to the determining that inter-frequency cell reselection should be performed, reselecting a cell from a group of candidate cells based on respective cell priorities of the candidate cells of the group, and respective frequency priorities of frequencies employed by the candidate cells of the group. 
   
     
     
         9 . The mobile device of  claim 8 , wherein the reselecting is further based on respective signal strengths of the candidate cells. 
     
     
         10 . The mobile device of  claim 8 , wherein the reselecting is further based on respective mobile device priorities of mobile devices operating using the candidate cells. 
     
     
         11 . The mobile device of  claim 8 , wherein the respective cell priorities are based on respective loads of the candidate cells. 
     
     
         12 . The mobile device of  claim 8 , wherein the respective cell priorities are based on respective bandwidths of the candidate cells. 
     
     
         13 . The mobile device of  claim 8 , wherein the group of candidate cells comprises macro cells and small cells, and the smalls cells have higher cell priorities than the macro cells. 
     
     
         14 . The mobile device of  claim 8 , wherein the operations further comprise assigning respective weights to the respective cell priorities and the respective frequency priorities. 
     
     
         15 . A non-transitory machine-readable medium, comprising executable instructions that, when executed by a processor of a user equipment, facilitate performance of operations, comprising:
 determining that inter-frequency radio node reselection should be performed during idle mode; and   in response to the determining, reselecting a radio node from a group of radio nodes based on respective radio node priorities of the radio nodes of the group, and respective frequency priorities of frequencies employed by the radio nodes of the group.   
     
     
         16 . The non-transitory machine-readable medium of  claim 15 , wherein the reselecting is further based on respective signal strengths of the radio nodes. 
     
     
         17 . The non-transitory machine-readable medium of  claim 15 , wherein the reselecting is further based on respective user equipment priorities of a group of user equipment, comprising the user equipment, connected to the radio nodes. 
     
     
         18 . The non-transitory machine-readable medium of  claim 15 , wherein the respective radio node priorities are based on respective loads of the radio nodes. 
     
     
         19 . The non-transitory machine-readable medium of  claim 15 , wherein the respective radio node priorities are based on respective bandwidths of the radio nodes. 
     
     
         20 . The non-transitory machine-readable medium of  claim 15 , wherein the group of radio nodes comprises macro radio nodes and small radio nodes, and the small radio nodes have higher radio node priorities than the macro radio nodes.
