Below in conjunction with Fig. 1 to system shown in Fig. 3 and equipment shown in Fig. 4 to terminal provided by the embodiments of the present application Connected state control method be specifically addressed.
First, in conjunction with the connected state control system 10 of terminal shown in FIG. 1, the connection of terminal provided by the embodiments of the present application State control method includes：Second network equipment determines whether the terminal in connected state has user plane data transfer；If the second net Network equipment determines that the terminal in connected state does not have user plane data transfer, second network equipment to refer to the transmission of first network equipment Show information, the user plane data transfer which is used to indicate the terminal in connected state is over.In this way, the first net Network equipment receives the instruction information from second network equipment, and according to the instruction information, initiates the connection release flow, the connection Release flow is used to terminal becoming Idle state from connected state.That is, the connected state controlling party of terminal provided by the embodiments of the present application In method, after introducing light weight connected state or inactive connected state, second network equipment can be perceived in connected state Whether terminal has user plane data transfer, and after determining that the terminal in connected state does not have user plane data transfer, refers to Show that first network equipment initiates the connection release flow, which is used to terminal becoming Idle state from connected state, from And solve network side because can not perception terminal user plane data transfer state and passively terminal can only be always maintained at The technology of connected state is limited to, and allows operator that can carry out control on demand to the terminal in connected state, for example will be in for a long time Connected state but the terminal of no user plane data transfer does not become Idle state from connected state, to save unnecessary network with Interface-free resources improve the runnability and efficiency of network.
Secondly, 4G LTE/EPC networks as shown in Figure 2 are applied to the connected state control system 10 of terminal shown in FIG. 1 For, expansion explanation is carried out to the connected state control method of above-mentioned terminal.
In a kind of possible realization method, as shown in figure 5, being a kind of connected state control of terminal provided by the embodiments of the present application Method flow schematic diagram processed.The connected state control method of the terminal is related to terminal, base station, the service MME of terminal and terminal SGW between interaction, include the following steps：
S501, terminal enter connected state from Idle state.
It could be carried out specifically, the transmission of user face data needs terminal to enter connected state from Idle state.
Uplink user face data is transmitted：Typically, terminal originating service request (Service Request) flow, The service request flow is used to terminal becoming connected state from Idle state.
Downlink user face data is transmitted：The SGW of terminal sends downlink data notification (Downlink Data to MME Notification, DDN) message, triggers MME and initiates to page to the terminal.In turn, as page response, terminal originating service Flow, the service request flow is asked to be used to terminal becoming connected state from Idle state.
It should be noted that different from the prior art in 4G networks, light weight connected state or inactive is being introduced After connected state, after the completion of the user plane data transfer of the terminal in connected state, in order to keep terminal network side always In connected state, the base station of 4G mobile communications networks can't start inactive (User Inactivity) timer of user, from And MME is caused not perceive the user plane data transfer state of the terminal, so that the terminal be allowed to keep connected state always.
S502, SGW start the first inactivity timer (inactivity timer).
Specifically, first inactivity timer is currently at the user face data of the terminal of connected state for SGW detections Whether transmission state is inactive, therefore the timer is referred to as user plane inactivity timer (user plane inactivity timer).Wherein, which can be set and changed by operator, also may be used To be pre-configured with a default value on SGW, for example 30s, the embodiment of the present application are not especially limited this.
It should be noted that in the embodiment of the present application, SGW is typically to be on connected state and terminal not having user in terminal Face data just starts first inactivity timer when transmitting.Certainly, SGW can also be on connected state and terminal in terminal and have Start first inactivity timer when upstream or downstream data transmission, the embodiment of the present application is not especially limited this.
If S503, in the first inactivity timer time-out, SGW does not receive the upstream or downstream signaling or data of terminal, Then SGW determines that terminal does not have user plane data transfer.
Optionally, if before the first inactivity timer time-out, SGW receives the upstream or downstream signaling or data of terminal, Then SGW stops the first inactivity timer.
Illustratively, it is assumed that the timing length of the first inactivity timer is set as 30s, and SGW is to be in connection in terminal There is no the first inactivity timer just started when user plane data transfer in state and terminal, then it is inactive to start first in SGW After timer：
If not receiving the upstream or downstream signaling or data of terminal within 30s, SGW determines that terminal does not have user plane number According to transmission.
If receiving the upstream or downstream signaling or data of terminal within 30s, SGW stops the first inactivity timer. After upstream or downstream signaling or the data transfer ends, SGW can restart the first inactivity timer, if 30s it The upstream or downstream signaling or data of terminal are not received inside, then SGW determines that terminal does not have user plane data transfer.If conversely, The upstream or downstream signaling or data of terminal are still received within 30s, then SGW stops the first inactivity timer, with reference to above-mentioned mistake Journey continues to execute, and details are not described herein.
Alternatively, illustrative, it is assumed that the timing length of the first inactivity timer is set as 30s, and SGW is in terminal There is the first inactivity timer started when upstream or downstream data transmission on connected state and terminal, then starts first not in SGW After active time：
If receiving the upstream or downstream signaling or data of terminal within 30s, SGW stops the first inactivity timer. After if SGW restarts the first inactivity timer, the upstream or downstream signaling or data of terminal are still received within 30s, then SGW Still stop the first inactivity timer.After SGW restarts the first inactivity timer, terminal is not received within 30s Upstream or downstream signaling or data, then SGW determine that terminal does not have user plane data transfer.
It is determined in connected state it should be noted that being merely exemplary a kind of SGW of offer in step S502 and S503 Whether terminal has the specific implementation of user plane data transfer, and certainly, SGW determines whether the terminal in connected state has user plane number Other realization methods are there may also be according to transmission, for example, SGW can preserve the user plane data transfer state of terminal, if terminal User plane data transfer state become inactive state from active state, then SGW can determine that terminal does not have user face data Transmission.Alternatively, the dimension of a time is may be incorporated into, but the dimension of time can be started without timer when realizing, For example judged by the inquiry system time twice, if inquire that terminal do not have user plane data transfer twice in succession is Interval between the system time equals or exceeds preset time interval, then SGW can determine that the terminal does not have user face data biography It is defeated.The embodiment of the present application determines whether the terminal in connected state has the realization method of user plane data transfer not make to have to SGW Body limits.
