摘要： Techniques are provided for transmitting and receiving communications on behalf of wireless user equipment devices between a plurality of radio access point (RAP) devices and a gateway apparatus through a controller apparatus. A controller apparatus generates a plurality of first identifiers used for communications on behalf of corresponding wireless user devices between the controller apparatus and respective RAPs. Each first identifier identifies a wireless user device and a RAP to which the wireless user device is associated. The controller apparatus maps each first identifier to a corresponding one of a plurality of second identifiers for communications exchanged on behalf of the wireless user devices between the controller apparatus and a gateway apparatus in the wireless cellular communication network. The controller apparatus remaps a new first identifier to an existing second identifier when a particular wireless user device has handed over from a first RAP to a second RAP.

摘要： A method and apparatus are provided for managing radio access point (RAP) devices and enterprise controller devices in a wireless communication network. An enterprise controller device registers with a gateway device, and the enterprise controller device receives a registration request from multiple RAP devices that are serviced by the enterprise controller device. As the RAP devices register with the enterprise controller device, the enterprise controller device generates a list of the RAP devices registered with the enterprise controller. As the enterprise controller receives additional registration requests from additional RAP devices, the enterprise controller updates the list. The enterprise controller sends the list to the gateway device with which it registers so that the gateway device is aware of RAP devices serviced by the enterprise controller device. In this way, aggregated messages may be sent from the gateway device to the enterprise controller.
