Method of time sequence control for access layer and non-access layer message

Abstract

The invention discloses a time sequence control method of the message of access layer and disaccess layer that can avoid the time sequence failure occurred when it sends and receives the direct-access message and signaling message, and can avoid the drop caused by the signaling message arriving at user device before the direct-access message. The method includes the following steps: A. the core network sends signaling message to wireless network controller; B. the ground wireless access network side of the general communication mobile system judges whether the current corresponding domain is sending down direct-access message, if yes, the step C would be executed, else turn into step D; C. the ground wireless access network side of the general mobile communication system waits for the finish of the direct-access message and turn into step D; D. the wireless network controller sends signaling message to user device.

Description

technical field [0001] The invention relates to a timing control method for sending and receiving messages in a mobile communication system, in particular to a timing control method for sending and receiving messages between an access layer and a non-access layer in the mobile communication system. Background technique [0002] In the existing Wideband Code Division Multiple Access (WCDMA) communication system, when a call is made, the signaling plane of the access layer (including the transmission network layer and the wireless network layer signaling plane) is first established. ), and then establishes the non-access stratum signaling plane. When releasing, the non-access stratum message of the core network and the user equipment first completes the interaction, and then the core network triggers the release of the access stratum signaling plane. [0003] The interaction process between the access layer signaling message and the non-access layer direct message in the above...

Problems solved by technology

[0007] As mentioned above, the signaling message "RRC CONNECTION RELEASE" is sent from the radio link control layer corresponding to SRB1, and the direct transfer message "DIRECT TRANSFER" is sent from the radio link control layer corresponding to SRB3 or SRB4. From the perspective of the level, SRB1 is higher than SRB3 and SRB4, and the signaling message is smaller. In addition, there may be more data packets on the radio link control layer corresponding to SRB3 or SRB4. The out-of-sequence of the direct transmission message and the signaling message appears on the UU interface between them, that is, as shown in Figure 1, on the IU interface, the direct transmission message arrives at the UTRAN side before the signaling message "IU RELEASE COMMAND", but on the UU interface However, the direct transmission message arrives at the user equipment side slower than the signaling message "RRC CONNECTION RELEASE"

[0008] In this case, the user equipment will release the access layer after receiving "RRC CONNECTION RELEASE", so that the received non-access layer direct message will be discarded and cannot be transmitted to the user equipment's non-access layer
