Abstract

A method for sharing an associated control channel in a mobile communication system is disclosed, which comprises the steps of: assigning a physical associated control channel between a mobile station and a base station and assigning a number of logical channels to the associated control channel, in order that a number of users can request communication service simultaneously through the mobile station; setting a logical link identification and a link setting flag not used when the mobile station receives a request for a new call setting, and transmitting a connection setting request to the base station through the physical associated control channel; informing the mobile station that the connecting and setting of logical link identification is completed through the physical associated control channel when the base station receives the connection request from the mobile station; and setting a traffic channel for transmitting user information after completing the connection setting.

Claims

1. A method for sharing an associated control channel in a mobile communication system, comprising the steps of:

assigning a physical associated control channel between a mobile station and a base station and assigning a number of logical channels to the associated control channel, in order that a number of users can request communication service simultaneously through the mobile station;

setting a logical link identification and a link setting flag not used when the mobile station receives a request for a new call setting, and transmitting a connection setting request to the base station through the physical associated control channel;

informing the mobile station that the connecting and setting of logical link identification is completed through the physical associated control channel when the base station receives the connection request from the mobile station; and

setting a traffic channel for transmitting user information after completing the connection setting.

2. The method according to claim 1, wherein the setting a logical link step comprises the steps of:

transmitting a connection request intention to a mobile station hierarchy 2 protocol entity to connect calls using a desired primitive defined between hierarchies when a mobile station hierarchy 3 protocol entity receives a request for setting new calls from users;

transmitting the logical link identification and the link setting flag to the base station hierarchy 2 communication entity through the physical associated control channel when the protocol entity of the mobile station hierarchy 2 sets logical link identification and link setting flag is not used;

transmitting a connection request intention to a base station hierarchy 3 protocol entity using a suitable primitive defined between hierarchies when the base station hierarchy 2 protocol entity receives the logical link identification and the link setting flag from the mobile station hierarchy 2 protocol entity through the physical associated control channel; and

transmitting a connection setting request of the mobile station to an application hierarchy using a base station hierarchy 3 protocol entity.

3. The method according to claim 1, wherein the informing step comprises the steps of:

informing a hierarchy 3 protocol entity of the base station of the connection setting when a base station application hierarchy can accept the connection setting, and transmitting a connection acceptance intention to a hierarchy 2 protocol entity of the base station using a primitive of the hierarchy 3 protocol entity of the base station;

setting the same logical link identification that a communication entity transmitted by way of a physical hierarchy by the hierarchy 2 protocol entity base station, and then transmitting the logical link identification to the hierarchy 2 protocol entity of the mobile station;

informing a hierarchy 3 protocol entity that the requested connection setting has been completed using a suitable primitive defined between hierarchies by the hierarchy 2 protocol entity of the base station which received the same logical link identification that the mobile station transmitted; and

informing that the connection was set to the application hierarchy which received the connection request from the user using a hierarchy 3 protocol of the mobile station.
