Method, apparatus and system for sharing network resources

Abstract

A method for sharing network resources includes: setting a sharing group based on service types in the process of setting up a bearer and determining a maximum network resource for the sharing group; and allocating a resource for the bearer in the range of the maximum network resource. The present invention also provides a system and an apparatus for sharing network resources. The embodiments of the present invention implement the sharing of a maximum transmission rate among multiple bearers in an evolved network, solve the problem of low network resource utilization caused by the fact that each bearer occupies a fixed bandwidth resource, and implement maximum utilization of network resources.

What is claimed is: 
     
         1 . A method for sharing network resources, comprising:
 determining, by a Packet Data Network (PDN) gateway connecting a User Equipment (UE) and a PDN or by an Evolved NodeB (ENB) corresponding to the UE, a preset maximum network resource corresponding to the UE, on the PDN when the UE sets up a bearer with the PDN; and   allocating, by the PDN gateway or by the ENB , a resource for the bearer in a range of the preset maximum network resource according to the preset determined maximum network resource.   
     
     
         2 . The method of  claim 1 , wherein the determining, by the PDN gateway, the preset maximum network resource corresponding to the UE comprises:
 obtaining, by the PDN gateway, a present maximum network resource through a Mobility Management Entity (MME) from a Home Subscriber Server (HSS).   
     
     
         3 . The method of  claim 1 , wherein the allocating, by the PDN gateway, the resource for the bearer in the range of the preset maximum network resource comprises:
 configuring, by the PDN gateway, the preset maximum network resource; and   allocating, by the PDN gateway, the resource for the bearer in the range of the configured maximum network resource.   
     
     
         4 . The method of  claim 1 , wherein the preset maximum network resource is Packet Data Network - Aggregate Maximum Bit Rate (PDN-AMBR). 
     
     
         5 . The method of  claim 1 , wherein the determining, by the ENB, the preset maximum network resource corresponding to the UE comprises:
 obtaining, by the ENB, a present maximum network resource through a Mobility Management Entity (MME) from a Home Subscriber Server (HSS).   
     
     
         6 . The method of  claim 1 , wherein the allocating, by the ENB, the resource for the bearer in the range of the preset maximum network resource comprises:
 configuring, by the ENB, the preset maximum network resource; and   allocating, by the ENB, the resource for the bearer in the range of the configured maximum network resource.   
     
     
         7 . A Packet Data Network (PDN) gateway, comprising:
 an obtaining unit, configured to obtain a preset maximum network resource corresponding to a User Equipment (UE), on a PDN when the UE sets up a bearer with the PDN, and send the preset maximum network resource to the allocating unit; and   an allocating unit, configured to receive the preset maximum network resource and allocate a resource for the bearer in the range of the preset maximum network resource.   
     
     
         8 . The PDN gateway of  claim 7 , wherein the obtaining unit is configured to obtain the present maximum network resource through a Mobility Management Entity (MME) from a Home Subscriber Server (HSS). 
     
     
         9 . The PDN gateway of  claim 7 , wherein the allocating unit, is configured to configure the preset maximum network resource; and allocate the resource for the bearer in the range of the configured maximum network resource. 
     
     
         10 . The PDN gateway of  claim 7 , wherein the preset maximum network resource is Packet Data Network - Aggregate Maximum Bit Rate (PDN-AMBR). 
     
     
         11 . An Evolved NodeB (ENB), comprising:
 an obtaining unit, configured to obtain a preset maximum network resource corresponding to a User Equipment (UE), on a Packet Data Network (PDN) when the UE sets up a bearer with the PDN, and send the preset maximum network resource to the allocating unit; and   an allocating unit, configured to receive preset the maximum network resource and allocate a resource for the bearer in the range of the preset maximum network resource.   
     
     
         12 . The ENB of  claim 11 , wherein the obtaining unit is configured to obtain the present maximum network resource through a Mobility Management Entity (MME) from a Home Subscriber Server (HSS). 
     
     
         13 . The ENB of  claim 11 , wherein the allocating unit is configured to configure the preset maximum network resource; and allocate the resource for the bearer in the range of the configured maximum network resource.
