Embodiment
The present invention basic thought be：When application server needs to obtain the monitoring data of certain terminal or some terminals, need
Triggering terminal is wanted to establish the connection with application server.But when being triggered to terminal, since the state of terminal is different,
Need the triggering mode of selection also can be different, interoperability functional entity passes through core after receiving for the triggering instruction of terminal
Heart network entity obtains the state of terminal, and corresponding triggering instruction is sent to terminal according to the SOT state of termination by core network entity,
The triggering established so as to the connection that ensure that to different conditions terminal.
It is by the following examples and referring to the drawings, right for the object, technical solutions and advantages of the present invention are more clearly understood
The present invention is further described.
Embodiment one
Fig. 2 is the flow chart of the terminal access method of the embodiment of the present invention, as shown in Fig. 2, the terminal of the embodiment of the present invention
Cut-in method specifically includes following steps：
201st, when machine type communication (MTC, Machine Type Communication) application server was needed from end
When end obtains real time data, the triggering sent to interoperability functional entity to the terminal indicates.Outside is included in triggering instruction
Mark, is triggered the effective time of instruction, or/and the maximum times sent, the address of MTC application servers.
In this example, the mark that terminal uses outside mobile communications network is known as outer logo；In mobile communications network
The mark that inside uses is known as internal indicator.And the inside and outside mark of each terminal is preserved in the functional entity that interoperates
The table of comparisons.
202nd, after interoperability functional entity receives the triggering instruction of terminal, the outer logo of reading terminals, inquiry control
Table, obtains the internal indicator of the terminal.
203rd, interoperate internal indicator of the functional entity according to acquisition, builds new triggering instruction, original triggering is referred to
Show that middle outer logo is substituted for internal indicator, and triggering instruction is sent to home subscriber service network element (HSS/HLR).
204th, the internal indicator during HSS/HLR is indicated according to triggering inquires about terminal state in which, if terminal is in
Wire state, then HSS/HLR is sent to the mobility management unit (MME/SGSN) of the terminal current service by instruction is triggered；Such as
Fruit terminal is in off-line state, then triggering instruction is sent to signing positional information by HSS/HLR according to the signing information of terminal
Associated MME/SGSN.
205th, after MME/SGSN receives triggering instruction, local terminal contextual information is inquired about according to the mark of terminal.
If terminal is online, MME/SGSN need preserve terminal status information, such as online terminal whether with net
Network has data connection.Specifically, can also be described as when terminal does not have data connection with network, MME/SGSN record terminals
State is Idle states, when terminal has data connection with network, Connected shapes when MME/SGSN records the state of terminal
State.
If terminal is online, and has data connection with network, then MME/SGSN passes through Non-Access Stratum
(NAS, Non Access Stratum) signaling is sent to terminal by instruction is triggered；
If terminal is online, and does not have data connection with network, then MME/SGSN sends paging message
To terminal；
If terminal is in off-line state, then MME/SGSN can send paging message and refer to terminal, or by triggering
Show and be sent to base station, triggering instruction is sent by base station broadcast.
Meanwhile the effective time that triggerings of the MME/SGSN in triggering instruction indicates, a timer is being locally located.
If receiving the attach request of terminal in timer, stop the timer.If end is not received by timer
The attach request at end, and trigger in instruction comprising the maximum times sent, then MME/SGSN can be sent again triggers instruction, most
Big number subtracts one, and resets timer；Until counts are 0 or receive the attach request of terminal；If indicated in triggering
In do not include send maximum times, then MME/SGSN send triggering failed message to HSS/HLR, or directly will triggering failure
Message is sent to interoperability functional entity.
206th, after terminal receives triggering instruction, attach request is initiated to MME/SGSN first, is being connected to mobile communication
After network, further according to the MTC application server address provided in triggering instruction, the connection with MTC application servers is established.
In the present invention, to realize that MTC terminal is set to MTC application server reported datas, IWF is connected to IWF
For example current mobile communications network of communication network and Data Management Network such as remote meter reading company's internal network etc..So as to fulfill
MTC terminal reports corresponding monitoring data etc. by mobile network etc. to Data Management Network.On technical solution of the present invention institute
Applicable specific business, due to not being related to the emphasis of technical solution of the present invention, nor (prior art is real for technological difficulties
It is existing), the present invention repeats no more.
The present invention also describes a kind of terminal access system, including belonging to interoperability functional entity, terminal, the terminal
Communication network, wherein：
Interoperate functional entity, after the triggering instruction of terminal is directed to for receiving, the triggering instruction is passed through described
The core net of the affiliated communication network of terminal is sent to the terminal；
The terminal, for establishing connection according to the triggering instruction.
The core net of the affiliated communication network of terminal includes home subscriber service network element and mobility management unit, its
In：
The interoperability functional entity is further used for, and the triggering instruction is sent to the home subscriber service network
Member；
The home subscriber service network element is used for, the identification information of the terminal in the triggering instruction, by institute
State the mobility management unit that triggering instruction is sent to the terminal association；
The mobility management unit, for the triggering instruction to be sent to the terminal.
The mobility management unit is further used for, by way of NAS signaling, system broadcasts or paging, by described in
Triggering instruction is sent to the terminal.
The home subscriber service network element is HSS or HLR；
The mobility management unit is MME or SGSN.
The HSS or HLR are further used for, and the state of the terminal are searched according to the identification information of the terminal, in institute
When stating terminal and being online, the triggering instruction is sent to the MME/SGSN of the terminal current service；At the end
When end is in off-line state, the triggering instruction is sent to the associated MME/SGSN of terminal unit contractual positional information.
The MME/SGSN is further used for,
When the terminal is online and has data connection, the triggering instruction is sent to by institute by NAS signaling
State terminal；
Alternatively, when the terminal is online and is connected with network no data, by paging message by the triggering
Instruction is sent to the terminal；
Alternatively, when the terminal is in off-line state, the triggering instruction is sent to by the terminal by paging message；
Alternatively, the triggering instruction is sent to base station, the terminal is sent to by system broadcasts by base station.
