Embodiment mono-
For the terminal of supporting resting state, if having described network side precognition, the present embodiment has downlink data transmission to this terminal after following a period of time, the temporal information that exits resting state is configured to this terminal, so that terminal enters after resting state at release connection, can in the corresponding time, exit resting state according to this temporal information.Its flow process can as shown in Figure 1, comprise:
Step 101: when terminal has data to send, initiate RRC and connect process of establishing, enter RRC_connected state, carry out transfer of data.Wherein, terminal sends to the RRC of network side to connect to set up in request message and carries sign, and to indicate whether to support resting state, network side knows according to this sign whether this terminal possesses the ability of resting state.Network side can also know whether this terminal has the ability of resting state by core network entity.
Step 102: for the terminal of supporting resting state, the long period does not have transfer of data if network side detects terminal, sends RRC connection release message, wherein carries and is used to indicate the temporal information that terminal exits resting state.
During concrete enforcement, network side is before sending RRC connection release message to terminal, if can know in advance, after following a period of time, (this time span is configurable) has downlink data need to be transferred to this terminal, in RRC connection release message, carry temporal information, with indicating terminal, in the corresponding time, exit resting state.If in a foreseeable future do not have downlink data need to be transferred to this terminal, network side sends RRC connection release message to terminal, and this message can adopt existing RRC connection release message form.
Such as, server need to carry out upgrade maintenance, due to the 0:00 after 3 days, reopens, and server notifies this information to core net.Core net, when terminal under this server sends RRC connection release message, is carried temporal information, is used to indicate terminal certain time after 3 days to exit resting state.The time that this temporal information is indicated can be that server reopens time+random delay.
Step 103: terminal is received after this RRC Connection Release request message, according to old process, enter resting state, if carry temporal information in RRC connection release message, after entering resting state, start timer QDT, the timing time of timer QDT is set, to exit resting state in the specified time of network side according to this temporal information.Specifically, the timing duration of timer QDT is: the moment of exiting resting state of notifying from current time to network side, then deduct the time span that terminal is carried out Cell searching and initiated to be connected.
Step 104: when timer QDT is overtime, terminal exits resting state.
During concrete enforcement, terminal exits after resting state, can have following several processing procedure:
Processing procedure one: terminal is carried out Cell searching, residently enters idle condition to a suitable community, monitoring ICQ in setting long-time section (this time span can arrange).Network side is this time point (being the time point that notification terminal exits resting state), if clearly there is downlink business demand, and request message is set up in the RRC connection of not receiving this terminal, to this terminal, send paging, after terminal and network side establish a communications link and complete transfer of data, if terminal is not received the time of exiting resting state next time, according to normal flow, enter resting state, otherwise according to aforementioned flow performing.If network side does not have business to communicate by letter at this time point (being the time point that notification terminal exits resting state), can there be two kinds of processing modes:
Mode one: this terminal of not paging of network side, terminal does not receive the paging of network side in the long-time section of this setting, reenters resting state;
Mode two: network side sends a special paging (carry special identifier, be different from conventional paging to indicate this paging) to this terminal, terminal needn't be initiated RRC connection foundation request after receiving this special paging, but enters resting state.Further, in this special paging, can carry the temporal information that exits resting state next time and (can certainly not carry the temporal information that exits resting state, need to be depending on the needs of transfer of data), in this case, terminal arranges the timing duration of timer QDT according to this temporal information, so that in corresponding duration backed off after random resting state.
Processing procedure two: terminal is resident behind a suitable community, initiates communication process one time, once communicates by letter with network.If network side has data need to send to this terminal, after terminal and network side establish a communications link to this terminal transmission downlink data, and after the end of transmission, discharge the communication connection with this terminal; If network side does not have data to need to send, after certain time length, discharge the communication connection with this terminal.Further, network side can carry the temporal information that exits resting state next time in connection release message, and terminal can be carried out respective handling after receiving this connection release message.
