- MOBILE COMMUNICATION SYSTEM MOBILE DEVICE AND COMMUNICATION PROCESSING END TIME REDUCTION METHOD USED FOR THEM
- the present invention relates to a mobile communication system, a mobile device, and a communication processing end time shortening method used for them, and more particularly to a communication processing end time shortening method for a 3G (Third Generation) mobile device (UE: User Equipment).
- 3G Third Generation
- UE User Equipment
- the transmission control apparatus When the transmission control apparatus requests transmission of control information indicating delivery confirmation for transmission information from the receiving side, the transmission control apparatus adds control information indicating delivery confirmation to the transmission information to be transmitted that exists at that time.
- RLC Radio Link Control
- STATUS PDU setting block and transmission information identification code with control information indicating delivery confirmation are stored in association with control information indicating delivery confirmation.
- STATUS PDU retransmission And a buffer.
- the above method requires a STATUS-PDU retransmission buffer that stores the identification code of transmission information provided with control information indicating delivery confirmation in association with control information indicating delivery confirmation. Control is complicated and an internal buffer is also required.
- the transmission / reception operation between the UE and the UTRAN is as follows. “RRC (Radio Resource Control) CONNECT! ON RELEASE COMPLETE MESSAGE” at the end of communication is the maximum number of retransmissions.
- RRC Radio Resource Control
- FIG. 1 shows a conventional process.
- Figure 1 shows the operation on the UTRAN side and the UE operation. is doing.
- "RRC CONNECTION RELEASE COMPLETE M ESSAGE" from the UE side is received by UTRAN (bl, b2 in Fig. 1)
- the UE enters an error monitoring state.
- B4 in Fig. 1 When synchronization is detected and a loss of synchronization is detected (b7 in Fig. 1), DCH ERR IND (INDicator) is detected (b9 in Fig. 1) and a DCH close request is issued. (BlO in Fig. 1).
- the T312 timer (Timer) value is specified in 3s (seconds)! /, It will take 3s until DCH close processing (until disconnection).
- Patent Document 1 Japanese Unexamined Patent Application Publication No. 2005-094230
- an object of the present invention is to provide a mobile communication system, a mobile device, and a method for shortening the communication processing end time used for them, which can solve the above-mentioned problems and reduce the time for communication end. is there.
- a mobile communication system includes mobile communication including a mobile device having a hierarchical structure of RRC (Radio Resource Control), RLC (Radio Link Control), MAC (Medium Access Control), and PHY (PHYsical 1 ayer).
- RRC Radio Resource Control
- RLC Radio Link Control
- MAC Medium Access Control
- PHY PHYsical 1 ayer
- the mobile station determines a threshold value of an RLC-UM (Unacknowledged Mode) transmission request from the RLC to the MAC based on the number of transmissions between the RLC and the MAC of the RLC-UM transmission request, and the determination result The number of transmissions of the RLC-UM transmission request is controlled accordingly.
- RLC-UM Unacknowledged Mode
- a mobile device includes RRC (Radio Resource Control), RLC (Radio Link).
- RRC Radio Resource Control
- RLC Radio Link
- the RLC-UM (Unacknowledged Mode) transmission request from the RLC to the MAC is determined as a threshold by the number of transmissions between the RLC and the MAC of the RLC-UM transmission request, and the RLC is determined according to the determination result. — The number of transmissions of UM transmission requests is controlled.
- the communication processing end time shortening method according to the present invention is used for a mobile device having a hierarchical structure of RRC (Radio Resource Control), RLC (Radio Link Control), MAC (Medium Access Control), and PHY (PHYsical layer).

- MAC Medium Access Control
- PHY PHYsical layer
- the mobile station determines a threshold value of an RLC-UM (Unacknowledged Mode) transmission request from the RLC to the MAC based on the number of transmissions between the RLC and the MAC of the RLC-UM transmission request, and the determination result The number of transmissions of the RLC-UM transmission request is controlled accordingly.
- the setting in the RLC (Radio Link Control) ⁇ MAC (Medium Access Control) layer in the UE (User Equipment: mobile device) is UTRAN (Universal Terrestrial Radio Access Network).
- the MAC-DATA-REQ transmission count is retained in the MAC, and the retained transmission count> threshold (MAC transmission count If the value exceeds the specified value, MAC-STATUS-IND (INDica tor) will cause RLC to shift to transmission stop processing.
- the transmission stop processing is performed by reducing the number of MAC-DATA-REQ repeated during execution of synchronization determination.
- the DCH close process is performed, the communication is terminated (dedicated resources and all procedures are terminated), and the communication termination time can be reduced.
- the present invention can achieve the effect of reducing the communication end time.
