Embodiment 1

[0062] like figure 1 The shown invention provides a method for controlling equipment, the method includes:

[0063] Step 101: the network device sends an RBC message to the terminal, and starts a first timer, and the duration of the first timer is determined according to the transmission parameters of the network device and the terminal;

[0064] Step 102: before the first timer expires, if the network device detects an RLC unrecoverable error message reported by the local radio link control RLC layer or receives a specified type of message, perform resource fallback for the terminal;

[0065] Step 103: Request the serving base station of the terminal to delete the wireless link of the terminal to trigger the terminal to perform cell update.

[0066] Preferably, in step 102, the received message of a specified type includes but is not limited to one of the following:

[0067] A cell update message sent by the terminal;

[0068] A wireless link failure message sent by the se...

Embodiment 2

[0099] like figure 2 The shown flow of a method for RBC message processing provided by the embodiment of the present invention is based on application scenario 1, that is, before the first timer expires, the RNC receives the cell update message reported by terminal A, then the embodiment of the present invention The specific steps provided for processing RBC messages are as follows:

[0100] Step 201: RNC allocates local resources for terminal A;

[0101] Step 202: RNC sends a configuration Radio Link request message to the serving base station (Node B) of terminal A;

[0102] Step 203: RNC receives the configuration Radio Link response message fed back by Node B;

[0103] Step 204: RNC sends an RBC message to terminal A, and starts a first timer;

[0104] Wherein, the RBC message may be any one of Radio Bearer Setup, Radio Bearer Releaser, Radio Bearer Reconfiguration, Physical Channel Reconfiguration, and Transport Channel Reconfiguration messages.

[0105] Step 205: th...

Embodiment 3

[0113] like image 3 The flow of a method for processing an RBC message provided by the embodiment of the present invention is shown. The flow is based on application scenario 2, that is, before the first timer expires, the RNC on the network side detects the RLC unrecoverable error message reported by the local RLC, then The specific steps for processing the RBC message provided by the embodiment of the present invention are as follows:

[0114] Step 301: RNC allocates local resources for terminal A;

[0115] Step 302: RNC sends a configuration Radio Link request message to the serving base station (Node B) of terminal A;

[0116] Step 303: RNC receives the configuration Radio Link response message fed back by Node B;

[0117] Step 304: RNC sends an RBC message to terminal A, and starts a first timer;

[0118] Wherein, the RBC message may be any one of Radio Bearer Setup, Radio Bearer Releaser, Radio Bearer Reconfiguration, Physical Channel Reconfiguration, and Transport Cha...

Abstract

The invention discloses a radio bearer control (RBC) message processing method and device. A network device sends an RBC message to a terminal and starts a first timer, the timing duration of the first timer being determined according to the transmission parameters of the network device and the terminal; if the network device detects a wireless link failure message of the terminal or receives a designated type message sent by the terminal before time out of the first timer, resource return is carried out on the terminal, and a service base station of the terminal is requested to delete the wireless link of the terminal to trigger the terminal to carry out cell updating, an RNC is allowed to return network side resources in time according to the difference of the transmission parameters so as to prevent meaningless waiting, and meanwhile, the wireless link is deleted to urge the terminal to report the cell updating to carry out rescue.

Description

technical field [0001] The present invention relates to the communication field, in particular to a radio bearer control RBC message processing method and device. Background technique [0002] In the TD-SCDMA (Time Division-Synchronous Code Division Multiple Access, Time Division Synchronous Code Division Multiple Access) network, the RRC (Radio Resource Control) of the UTRAN (Universal Terrestrial Radio Access Network, Universal Terrestrial Radio Access Network) , radio resource control) layer through the RBC (Radio Bearer control, radio bearer control) process instructs the terminal to perform the service establishment, reconfiguration, release process of the cell or the handover process of the cell, and the network side RNC (Radio Network Controller, radio network controller) The RRC layer uses AM (Acknowledged Mode, confirmation mode) to send an RBC message to the terminal. After the RNC sends the RBC message, the air interface timer is started. The air interface timer i...
