What is Work of Paging Channel in CDMA?The Paging Channel in CDMA (Code Division Multiple Access) serves a crucial role in the efficient functioning of the communication system. As a dedicated control channel, the Paging Channel is responsible for transmitting important information, such as incoming calls and system messages, to mobile devices within a CDMA network.
By utilizing specific coding techniques and spreading sequences, the Paging Channel ensures that mobile devices remain in an idle state while awaiting incoming calls or system notifications. This first para provides an overview of the essential function and purpose of the Paging Channel in a CDMA network.
The paging channel transmits:
- System parameters message
- Access parameters
- Neighbors list
- CDMA channels list message
The paging channel accomplishes:
- Paging to MS
- Assign traffic channel to MS
- The frame length of a paging channel is 20ms
- W1 ~ W7 are spared for the Paging Channels spreading.
What is access channel and paging channel in mobile communication?
In mobile communication, the Access Channel and Paging Channel are two important components that facilitate communication between mobile devices and the network infrastructure.
The Access Channel is a dedicated channel used by mobile devices to establish initial communication with the network. It allows mobile devices to send signals to the base station, indicating their presence and the need to initiate a call or transmit data. The Access Channel is primarily used during call setup, call termination, and when a mobile device needs to request resources from the network. This channel is crucial for enabling mobile devices to access the network and establish communication links.
On the other hand, the Paging Channel serves as a control channel used by the network to alert mobile devices of incoming calls, messages, or other system notifications. It broadcasts paging messages to multiple mobile devices simultaneously, indicating that there is an incoming call or message waiting for them. Mobile devices monitor the Paging Channel periodically to check for any paging messages addressed to them. When a mobile device receives a paging message on the Paging Channel, it responds accordingly by establishing a connection on the Access Channel.
In summary, the Access Channel enables mobile devices to initiate communication with the network, while the Paging Channel allows the network to alert mobile devices of incoming calls or messages. Both channels play integral roles in mobile communication, ensuring efficient and effective communication between mobile devices and the network infrastructure.
