Abstract
A packet transmission control method is achieved by borrowing a first one of a plurality of channels for a first one of a plurality of existing users in response to a packet receiving request, and by transmitting packets to a new user using the first channel.
Claims17
A packet transmission control method, comprising:
- borrowing a first channel of a plurality of channels from one of a plurality of existing users in response to a packet receiving request and in response to detection of an empty period in use by said existing user of said first channel;
- transmitting packets to a new user using said first channel;
- and
- transmitting packets to said one of said plurality of existing users using said first channel, wherein the first channel is allocated to a base station serving said one of said plurality of existing users and the new user.
1 more element
A packet transmission control apparatus, comprising:
- a control unit monitoring a transmission situation to an existing user via a channel in response to a monitor request, and controlling a new user to receive packets;
- and
- a base station outputting said monitor request to said control unit in response to said packet receiving request from said new user, and transmitting the packets to said new user in response to the control of said new user by said control unit;
- wherein said channel is a voice channel, and wherein said control unit controls said existing user to stop a receiving operation when said control unit detects a voiceless portion of said channel, and controls said base station to transmit the packets to said new user.

A packet transmission control apparatus, comprising:
- a control unit monitoring a transmission situation to an existing user via a channel in response to a monitor request, and controlling a new user to receive packets;
- and
- a base station outputting said monitor request to said control unit in response to said packet receiving request from said new user, and transmitting the packets to said new user in response to the control of said new user by said control unit;
- wherein said channel is a data channel, and
- wherein said base station allocates a spreading code and a time slot of a frame to said new user in response to said packet receiving request and in response to detection of an empty period in use by said existing user of said data channel.
