A communication procedure may be used for multiple access. A wireless device may be capable of simultaneously accessing a plurality of networks that are associated with a visited network. The visited network may or may not allow the wireless device to simultaneously access the plurality of networks, for example, based on a status of the visited network. Prior to a wireless device requesting access to a plurality of networks, a visited network may indicate whether the visited network supports, for the wireless device, simultaneous access to a plurality of networks.

The application discloses a modulation and coding adaptive selection method for a mobile ad hoc network based on separation of a control plane and a data plane. In the mobile ad hoc network based on separation of the control plane and the data plane, a carrier sense multiple access (CSMA) mechanism is adopted in a control time slot to compete for sending fused situation information of itself, so as to complete survey and perception of neighbor nodes. The situation information includes link transmission quality and node queue length. In the data plane, the CSMA mechanism is also adopted, but the situation information of the control plane needs to be utilized to form certain 'network order', so as to reduce the decline of throughput caused by error packets and collision. On the basis of a traditional rate adaptive algorithm based on a signal-to-noise ratio (SNR), the algorithm is improved and applied to a mobile ad hoc network device based on separation of the control plane and the data plane.
