A wireless device sends, to a base station, at least one first radio resource control (RRC) parameter comprising at least one first identifier indicating at least one first closed access group (CAG) of a first cell. The at least one first RRC parameter is associated with a connection with the base station via the first cell. The wireless device receives at least one second RRC parameter comprising at least one second identifier indicating at least one second CAG that the wireless device is allowed to access. The wireless device selects a second cell associated with the at least one second CAG. The wireless device transmits a random access preamble via the second cell.

Systems, methods, and software described herein provide enhancements for the redirection of communication requests from a Long Term Evolution (LTE) network to a secondary wireless communication network. In one implementation, a method of operating a mobility management entity (MME) includes receiving, over a LTE network, channel status information for channels in a secondary wireless communication network from wireless communication devices. The method further provides receiving a communication request over the LTE network from a wireless communication device, and in response to the communication request, identifying a channel in the secondary wireless communication network to support the communication request based on the channel status information. The method also includes transferring a notification to the wireless communication device to indicate the identified channel.
