Embodiment Construction
[0034] The communication process generally starts with random access. The random access request is generally initiated by the upper layer of the user terminal and executed by the lower layer, such as initiated by the circuit domain mobility management (MM, Mobility Management) layer, which sends a connection establishment request to the radio resources (RR, Radio Resources) layer, and then by The RR sends a channel request to the network to establish a random access channel. The RR will also initiate a random access request. For example, after receiving a notification from the network, a paging message, or detecting a change in a received location code message, the RR can initiate a paging response, a notification response process, or a location update process (including random access channel establishment process).
