Core network device, access network device, and data offloading method and system

Abstract

Embodiments of the present disclosure provide a core network device, an access network device, and a data offloading method and system, and relate to the field of mobile communications. In the system, the access network device receives an offloading inclination indication of service data from the core network device; the access network device allocates, according to the offloading inclination indication, a transmission resource used for transmitting the service data; and the access network device transmits the service data by using the allocated transmission resource. In the present disclosure, quality of service (QoS) in the transmission process can be ensured even if data is offloaded by using a first resource such as an unlicensed spectrum, a transmission resource provided by Wireless Local Area Networks (WLAN), or a transmission resource provided by the secondary eNodeB.

What is claimed is: 
     
         1 . A data offloading method, wherein the method comprises:
 receiving quality of service (QoS) information of service data;   allocating, according to the QoS information, a transmission resource used for transmitting the service data, wherein the transmission resource comprises a transmission resource that belongs to a first resource and a transmission resource that belongs to a non-first resource, and the first resource comprises a long term evolution (LTE) carrier in an unlicensed spectrum, a transmission resource provided by a wireless local area network (WLAN), or a transmission resource provided by a secondary eNodeB; and   sending an offloading inclination indication of uplink service data to a terminal.   
     
     
         2 . The method according to  claim 1 , wherein the method further comprising:
 obtaining traffic statistics information respectively corresponding to the transmission resource that is used for transmitting the service data and belongs to the first resource and/or the transmission resource that is used for transmitting the service data and belongs to the non-first resource; and   sending the traffic statistics information to a core network device.   
     
     
         3 . The method according to  claim 2 , wherein the method further comprises:
 sending the traffic statistics information to the core network device through a primary base station.   
     
     
         4 . A method, comprises:
 receiving an offloading inclination indication of service data sent by an access network device;   determining a transmission resource used for transmitting the service data according to the offloading inclination indication;   wherein the offloading inclination indication comprises:   prohibiting transmission on a first resource; or   allowing transmission on a first resource; or   preferably transmission scheduling on a first resource; or   preferably transmission scheduling on a non-first resource.   wherein the first resource comprises a carrier in a spectrum, a transmission resource provided by a wireless local area network (WLAN), or a transmission resource provided by a secondary eNodeB.   
     
     
         5 . The method according to  claim 4 , wherein
 the spectrum is an unlicensed spectrum.   
     
     
         6 . The method according to  claim 4 , wherein
 the service data is uplink service data.   
     
     
         7 . An apparatus, comprising:
 one or more processors, and   a non-transitory storage medium configure to store program instructions;   wherein, when executed by the one or more processors, the instructions cause the apparatus to perform:   receiving quality of service (QoS) information of service data;   allocating, according to the QoS information, a transmission resource used for transmitting the service data, wherein the transmission resource comprises a transmission resource that belongs to a first resource and a transmission resource that belongs to a non-first resource, and the first resource comprises a long term evolution (LTE) carrier in an unlicensed spectrum, a transmission resource provided by a wireless local area network (WLAN), or a transmission resource provided by a secondary eNodeB; and   sending an offloading inclination indication of uplink service data to a terminal.   
     
     
         8 . The apparatus according to  claim 7 , wherein the instructions cause the apparatus further to perform:
 obtaining traffic statistics information respectively corresponding to the transmission resource that is used for transmitting the service data and belongs to the first resource and/or the transmission resource that is used for transmitting the service data and belongs to the non-first resource; and   sending the traffic statistics information to a core network device.   
     
     
         9 . The apparatus according to  claim 8 , wherein the instructions further cause the apparatus to perform:
 sending the traffic statistics information to the core network device through a primary base station.   
     
     
         10 . An apparatus, comprising:
 one or more processors, and   a non-transitory storage medium configure to store program instructions;   wherein, when executed by the one or more processors, the instructions cause the apparatus to perform:   receiving an offloading inclination indication of service data sent by an access network device;   determining a transmission resource used for transmitting the service data according to the offloading inclination indication;   wherein the offloading inclination indication comprises:   prohibiting transmission on a first resource; or   allowing transmission on a first resource; or   preferably transmission scheduling on a first resource; or   preferably transmission scheduling on a non-first resource.   wherein the first resource comprises a carrier in a spectrum, a transmission resource provided by a wireless local area network (WLAN), or a transmission resource provided by a secondary eNodeB.   
     
     
         11 . The apparatus according to  claim 10 , wherein
 the spectrum is an unlicensed spectrum.   
     
     
         12 . The apparatus according to  claim 10 , wherein
 the service data is uplink service data.
