Description

A kind of method and system for realizing UE controls

Technical field

The present invention relates to the communications field, and in particular to one kind realizes the method and system of user equipment (UE) control.

Background technology

At present, the communication service of machine to machine (Machine to Machine, M2M) is gradually used widely, For example, applied in logistics system, remote meter reading, smart home etc..M2M service providers are mainly carried out using existing wireless network M2M business, for example, General Packet Radio Service (General Packet Radio service, GPRS) network, evolution packet The PS networks such as system (Evolved Packet System, EPS) network.Due to M2M business and interpersonal communication (Human to Human, H2H) business has obvious otherness, therefore, it is necessary to carry out necessary optimization to network deployment, with Meet to obtain optimal network management and network communications quality while M2M applications.

System Architecture Evolution (System Architecture Evolution, SAE) is proposed to so that evolution Packet net (Evolved Packet System, EPS) can provide the transmission rate of higher, shorter transmission delay, optimization point Group, and support UTRAN (Evolved UTRAN, E-UTRAN), UTRAN, WLAN (the Wireless Local of evolution Area Network, WLAN) and other non-3 gpp access network between mobile management.

Fig. 1 is the Organization Chart of EPS, as shown in Figure 1, wherein, wireless access network (the Evolved Radio Access of evolution Network, E-RAN) in the network element that includes be enode b (Evolved NodeB, eNodeB), for the access for user Radio Resource is provided；Packet Data Network (Packet Data Network, PDN) is the network for the business that provides to the user；EPC is carried Lower delay has been supplied, and has allowed more wireless access systems to access, it includes following network element：

Mobile management entity (Mobility Management Entity, MME), is chain of command functional entity, deposits temporarily The server of user data is stored up, is responsible for and stores the context of UE (for example, user identifier, mobility management states, user Security parameter etc.), distribute temporary mark for user；When UE quarters at the tracing area or the network, it is responsible for the user Authenticated.

Gateway (Serving Gateway, SGW or S-GW), is a user entity, is responsible for user face data road By handling, the downlink data of UE of the termination in idle (ECM_IDLE) state.Management and the SAE carryings (bearer) of storage UE Context, such as IP bearer services parameter and network internal routing iinformation etc..SGW is the anchor point in 3GPP system internal user face, One user can only have a SGW a moment.

Packet data network gateway (PDN Gateway, PGW or P-GW), is responsible for the gateway of UE access PDN, distributing user IP address, and the mobility anchor of 3GPP and non-3 GPP access system, the function of PGW further include strategy implement, charging branch Hold.User has access to multiple PGW in synchronization.Strategy implements functional entity (Policy and Charging with charging Enforcement Function, PCEF) it also is located in PGW.

Strategy and charging regulation function entity (Policy and Charging Rules Function, PCRF), are responsible for Policy control and charging regulation are provided to PCEF.

Home subscriber server (Home Subscriber Server, HSS), is responsible for permanently storing user contracting data, The content of HSS storages includes international mobile subscriber identity (the International Mobile Subscriber of UE Identification, IMSI), the IP address of PGW.

Physically, above-mentioned SGW and PGW may unify, and EPC system user plane network element includes SGW and PGW.

MTC server is mainly responsible for the work such as information gathering and the data storage/processing to MTC UE, and can be to MTC UE Carry out necessary management.

MTC UE are generally responsible for collecting the information of some collectors, and by RAN node core network access, with MTC Server interaction datas.

In Fig. 1, MTC UE are needed by EPS networks to MTC Server or others MTC UE transmitting data informations. SAE networks establish the GTP tunnel between SGW-PGW for this transmission, and data message realizes transmitting by GTP tunnel.

Fig. 2 is under the prior art, and UE access to EPS networks simultaneously performs the flow chart in EPS network attachments.As shown in figure 3, Related attachment flow mainly includes the following steps that：

S201, in order to be linked into SAE networks, UE initiates network attachment request to eNodeB, carries IMSI, UE wherein Network accessibility, the information such as instruction of request distribution IP；

S202, eNodeB select a MME serviced for it for UE, and attach request is forwarded to the MME, while by UE The important information such as mark be also carried to the MME；

S203, MME send authorization data request message (containing IMSI) to HSS, and HSS first determines whether the corresponding signings of IMSI Data, have been put on the blacklist if searched less than any subscription data or IMSI, and HSS returns to authorization data to MME and rings Suitable error reason and should be carried；If finding the corresponding subscription data of IMSI, HSS returns to authorization data response to MME Message (contains authentication vector)；

MME performs authorizing procedure to verify the legitimacy of terminal IMSI, and performs safe mode flow and connected with enabling safety Connect.

S204, MME send position updating request to the HSS of home network, and mark, the mark of UE of MME are carried in message, with Inform the region that UE is currently accessed；

S205, HSS go out contracted user's data of UE according to the identifier lookup of UE, are then forwarded to MME.It is main in user data Include the information such as default access point title (Access Point Name, APN), amount of bandwidth；

MME receives user data, checks whether UE is allowed access to network, is returned to HSS and receives user response；If MME has found that UE has the problems such as roaming limitation or access restriction, and MME will forbid UE to adhere to, and notify HSS.

S206, HSS are sent to MME confirms location updating response；

S207, MME select a S-GW for UE, and are sent to establish the request of default bearing.In the request, MME Inform the necessary information of S-GW：The mark of UE, the mark of MME, for UE distribute the indicating of IP address, default bandwidth information, PDN GW addresses etc.；

S208, S-GW send the request for establishing default bearing to PDN GW.In the request, S-GW informs that PDN GW must The information wanted：The address of S-GW, default bandwidth information, be instruction that UE distributes IP address etc.；

S209, if it is necessary, PDN GW are asked as the UE strategies configured and charging regulation, decision information to PCRF；

S210, PDN GW establish default bearer, and return to S-GW according to the PCRF strategies returned and charging decisions information Response is established in carrying；

S211, S-GW send the response of default bearing foundation to MME；

S212, MME send attachment to eNodeB and receive response, show that UE is attached to the request of network and is received, wherein Carry Serving GW addresses and TEID (Tunnel Endpoint Identifier, tunnel port mark)；

S213, eNodeB send voice bearer to UE and establish request, it is desirable to which UE preserves the important information that carrying is established, and opens Put corresponding port.Carried in the request message：Bearer network ID, PDN GW addresses, the IP address for distributing to UE, bandwidth letter Breath etc.；

S214, UE send radio bearer to eNodeB and establish response；

S215, eNodeB notice MME attaching process are completed；

S216, MME send more new bearer request to S-GW, notify the mark for the UE eNodeB serviced, address；

S217, S-GW send the response of more new bearer to MME；

S218, is specified if PDN GW are not HSS, and MME sends notice request to HSS, and notice HSS is serviced by UE PDN GW address information, HSS updates the information.

It can be received according to existing terminal devices such as the existing PS network architectures described in Fig. 1 and Fig. 2, mobile phones and wirelessly connect Enter the wireless signal that network is sent, and be attached to by Radio Access Network in carrier network, then can carry out voice and lead to The business such as words.

Fig. 3 is the system architecture diagram according to the UTMS of correlation technique.UTMS networks by Universal Mobile Communication System land without Line access (Universal Terrestrial Radio Access Network, UTRAN), GPRS serving GPRS support nodes (SERVICING GPRS SUPPORT NODE, SGSN), GPRS gateway support node (Gateway GPRS Support Node, GGSN), attaching position register (Home Location Register, HLR) composition.

In figure 3, SGSN have this SGSN coverages end packet data packet by and forwarding capability, and with pair Terminal carries out the functions such as mobile management.GGSN provides route and encapsulation of the data packet between GPRS nets and external data network. PDN is the network for the business that provides to the user.HLR is used for storing user subscription data.Connect between SGSN and UTRAN using Iu-PS Port communications, by interface SGSN completions and the communication between UTRAN systems, terminal, to complete grouped data transmission, mobility Function in terms of management and session management.Foundation, release and the control of IP channels are completed between SGSN and GGSN by gn interface Etc. function.Data of the SGSN by Gr interface from HLR acquirements on terminal, the HLR preserve GPRS user data and routing iinformation. Gi interfaces are the interfaces between GPRS and outside PDN.GPRS is grouped net (such as Internet by Gi interfaces and the various public Or ISDN (Integranted Services Digital, ISDN)) realize interconnection, needed on Gi interfaces into When encapsulation/decapsulation of row agreement, address conversion (for example, privately owned net IP address conversion is publicly-owned net IP address), user access Authentication and the operation such as certification.

The definition of M2M in the narrow sense is the communication of machine to machine, it is sensu lato definition be using machine terminal intelligent interaction as Application and service of core, networking.It is to be based on intelligence machine terminal, using communication as access means, for visitor The informatization resolve scheme that family provides, for meeting information of the client to monitoring, command scheduling, data acquisition and measurement etc. Change demand.

An important factor for development of wireless technology is M2M market developments, it breaches the space-time limitation of conventional communication mode With region obstacle, enterprise and the public has been broken away from cable constraint, allow client more effectively control cost, reduce mounting cost and It is easy to use.Constantly advance in addition, growing demand driving M2M：With information processing capability and Netowrk tape Wide constantly to increase paradoxically, the means of acquisition of information lag far behind.And M2M meets this demand of people very well, lead to External environment condition can be monitored in real time by crossing its people, realize the information gathering of a wide range of automation.Therefore, M2M can be applied to go Industry application, domestic applications, individual application etc..Sector application is such as：Traffic monitoring, warning system, rescue at sea, automatic vending machine, Driving payment etc.；Domestic applications are such as：Automatic data logging, temperature control etc.；Individual application is such as：Life detection, remote diagnostics etc..

The communication object of M2M is Machine To Machine, Human-to-Machine.Data communication between one or more machines is defined as MTC (Machine Type Communication, machine type communication), in this case less need for human-computer interaction.Participate in The machine of MTC is defined as MTC device.MTC device is the terminal of MTC user, can be taken by PLMN networks and MTC device, MTC Business device communicates.ME (Mobile Equipment) is the subsidiary functional block of MTC device, which is used for MTC device It is linked into EPS systems.MTC server (MTC Server) is managed and monitors to MTC device.

Since MTC device is mostly the equipment of concrete application, different set is used as automatic data logging is detected from life It is standby etc..The MTC device of different application has different characteristics, and there is such as elevator lifter apparatus Hypomobility, PS only to belong to Property, and monitor, alert device in addition to Hypomobility, PS only, also with the attribute such as low data transfer and high availability. Therefore different system optimizations is carried out for the MTC device of different application, effectively MTC device can be managed, monitored, paid Take.

It is by time control to have a kind of communication of MTC applications, i.e., allows MTC device to connect within some specific periods Enter network or carry out sending and receiving for data, allowing then limit MTC equipment progress aforesaid operations outside the period.In HSS Contract time control：Access duration (access duration), it is allowed to period (grant time interval) and taboo Only period (forbidden time interval).SGSN/MME is obtained during attachment, position/routing update from HSS The signing information of time control is taken, and combines local policy as one call duration time window not less than access duration of device definition (communication window), and this communication time window is handed down to MTC device.In order to prevent during the communication of large number of equipment Between window is overlapping causes network congestion, network needs allowing randomized communication time window in the period.When SGSN/MME is by communication Between window MTC device is accessed or Service control.MTC device whether is allowed to carry out Signalling exchange and receipts outside communication time window Data are sent out, then are determined by carrier policy.There are two kinds of strategies in the prior art：One kind is refused outside time window, another It is that can be accessed outside time window, but charging is different.

In MTC applications, there are some scenes to need MTC Server triggering MTC devices to initiate the communication with MTC Server To carry out the transmission of data, such as：In the application of some supervision and reporting classes, except setting MTC equipment periodically on MTC Server Reporting outside monitoring report, MTC Server also can aperiodically ask MTC equipment to measure reporting for data, in this case, Just need MTC Server to MTC device send instruction with trigger MTC device be connected to network or establish data connection with MTC Server communicates.MTC Server can be by area triggering, can also be by a group triggering.But in the prior art, if Network is controlled MTC device according to call duration time window, and using the strategy refused outside time window, then it is all to be signed with time control The equipment MTC SERVER of system have no idea to trigger.This cause the equipment with signing time control attribute can not by region or By a group triggering.

Further, since the permission period of network contraction and disable time section are nonoverlapping periods, network is being forbidden Can be set in period does not allow to trigger MTC device, and at this moment network needs to refuse the triggering of MTC device.Otherwise, MTC Server has attempted to trigger request, can aggravate network burden, wastes Internet resources.

Embodiment

Technical solution of the present invention is described in further detail with specific embodiment below in conjunction with the accompanying drawings.

Applications trigger is to send triggering instruction to MTC device by network from application server, MTC device response triggering A kind of behavior.But in some cases, network may refuse touching for MTC equipment response application servers for various reasons Hair.Mainly there are following several situations：

1) triggering has the MTC device of time control attribute, and the triggered time is located at the disable time section of MTC device signing It is interior；

2) MTC device of the triggering with time control attribute, triggered time are in the permission period of MTC device signing Outside, but migration efficiency determines that MTC device is allowing not allow to trigger outside the period；

3) network congestion when triggering, migration efficiency determine whether the triggering (trigger) of application server urgent (such as： Can be determined whether urgent by trigger values), if non-emergent trigger networks can be refused.

In addition, Network Check is not limited to case above, may there are other situations, network needs to refuse application service at this time The trigger request of device.Fig. 4 is the flow chart whether the Network Check triggering of the embodiment of the present invention one allows.The inspection of network is divided into Two kinds, one kind is that HSS/HLR checks whether triggering allows, and one kind is that MME/SGSN checks whether triggering allows.Specifically include as Lower step：

Step 401a, application server is to HLR/HSS sending application trigger requests；

Step 402a, HSS/HLR check triggering of the application server to UE whether in the disable time section of UE, if In disable time section, HSS/HLR sends refuse information by step 403a to application server；

HSS/HLR is also possible to check whether triggering of the application server to UE runs counter to migration efficiency, the HSS/HLR if running counter to Refuse information is sent to application server by step 403a.Migration efficiency is such as：

A) being only allowed in allows period internal trigger, if then triggering allowed outside the period；

B) under particular case (such as：Network congestion etc.) if non-emergent trigger；

Step 403a, HSS/HLR return to reason for rejection (such as to application server：Send UE applications triggers refusal respond), Wherein carry suitable cause value.

401b~403b is the embodiment that MME/SGSN is checked.

Step 401b, application server is directly or indirectly to MME/SGSN sending application trigger requests；

Step 402b, MME/SGSN checks triggering of the application server to UE whether in disable time section, if prohibited Only in the period, MME/SGSN sends refuse information by step 403b to application server；

MME/SGSN is also possible to check whether triggering of the application server to UE runs counter to migration efficiency, the MME/ if running counter to SGSN sends refuse information by step 403b to application server；Migration efficiency is such as：

Step 403b, MME/SGSN directly or indirectly return to reason for rejection (such as to application server：Send UE applications triggers Refusal respond), wherein carrying suitable cause value.

Due to the particularity of the UE such as MTC device applications, some applications do not require UE real-time onlines, only require on certain time Count off evidence.This kind equipment most of time is in off-line state.At this moment triggering equipment, which is reached the standard grade, to be touched by broadcast triggering, short message The mode of hair.Triggering equipment can know that it is application layer by broadcasting triggering mode or short message triggering mode or other modes Triggering, by UE informing networks.Fig. 5 is the flow chart of the method for the invention.Specifically comprise the following steps：

Step 501, UE receives applications trigger request；

Step 502, UE sends NAS message request to eNodeB/RNC, and the instruction of UE applications triggers, the instruction are carried in request It is to receive the NAS message request initiated after applications trigger to show UE；NAS message requests mainly include：Attach request, business At least one of request, position updating request, routing update request.

Step 503, NAS message request is forwarded to MME/SGSN and (can be collectively referred to as mobile management list by eNodeB/RNC Member), the instruction of UE applications triggers is carried in the message；

Step 504, MME/SGSN checks the NAS message request of UE, if the UE applications triggers instruction in NAS message request It is the request received after applications trigger to show it, and then confirms that UE is that the request is initiated because of applications trigger, then MME/SGSN The UE operation flows initiated are controlled according to migration efficiency, specific strategy is：

1st, the NAS message request time of UE initiations is checked in disable time section；

2nd, migration efficiency is run counter in the NAS message request for checking UE initiations, such as：

A) being only allowed in allows period internal trigger, but the NAS message request that UE is initiated occurs allowing outside the period；

B) under particular case (such as：Network congestion etc.) NAS message initiated for non-emergent applications trigger response asks Ask；

MME/SGSN sends refuse information through eNodeB/RNC to UE, and suitable cause value is carried in message.

Step 505, if the NAS message request of UE passes through the inspection of step 504, after performing corresponding NAS message requests Afterflow journey；

Step 506, if MME/SGSN according to strategy (such as UE response applications trigger NAS message request allow the time In section but outside call duration time window；The non-emergent triggering of UE response applications) it is that UE regenerates a call duration time window, Then UE can be handed down to by NAS message response.MME/SGSN sends NAS message response to eNodeB/RNC, in the response message Carry new call duration time window；

NAS message response mainly includes：Attachment receives request, initialization context establishes request, location updating receives to disappear Breath and route received message etc..

Step 407, eNodeB/RNC sends NAS message response to UE, and new call duration time is carried in the response message Window.The replaceable original time window of the call duration time window or the call duration time window to use temporarily.

Another situation, network can know the equipment that needs trigger, the information for the UE to be triggered stored in network, works as UE During to network request, network can judge that equipment is to initiate to ask because of triggering.Fig. 6 is the flow chart of the method for the invention. Specifically comprise the following steps：

Step 601, UE sends NAS message request to eNodeB/RNC；NAS message request mainly includes：Attach request, industry At least one of business request, position updating request, routing update request；

Step 602, NAS message request is forwarded to MME/SGSN by eNodeB/RNC；

Step 603, MME/SGSN checks the NAS message request of UE, if MME/SGSN is true according to the UE information itself stored The request is recognized to receive the NAS message request after applications trigger, the then business that MME/SGSN initiates UE according to migration efficiency Flow is controlled, and specific strategy is：

Step step 604, if MME/SGSN can not judge whether the NAS message request of UE is caused by response application triggering Request, can apply judging, the request message by position updating request to HSS/HLR (can be collectively referred to as location information management unit) In may be selected to carry the instruction of UE applications triggers；

Step 605, HSS/HLR judges whether UE initiates because response application triggers according to the triggering information locally preserved Request, and by location updating response will determine that result is sent to MME/SGSN；

Step 606, the follow-up corresponding flow of NAS message request is performed；

Step 607a, deletes the information that the network preserved in MME/SGSN triggers UE.Such as：Timer can be set, and Deleted in timer expiry；Or when receiving the flow response of request, triggering information is deleted by MME/SGSN；

Step 607b, deletes the information that the network preserved in HSS/HLR triggers UE.Such as：Timer can be set, and Deleted during timer expiry；Or deleted after receiving the notification message of MME/SGSN；

Step 608, if MME/SGSN according to strategy (such as UE response applications trigger NAS message request allow the time In section but outside call duration time window；The non-emergent triggering of UE response applications) it is that UE regenerates a call duration time window, Then UE can be handed down to by NAS message response.MME/SGSN sends NAS message response to eNodeB/RNC, in the response message Carry new call duration time window.

Step 609, eNodeB/RNC sends NAS message response to UE, and new call duration time is carried in the response message Window.The replaceable original time window of the call duration time window or the call duration time window to use temporarily.

Another situation, network can know the equipment that needs trigger, and the information for the UE to be triggered is stored in network.UE is received To carrying triggering mark during network request after to trigger request, but the triggering mark that network is also required to UE checks, judges Whether the request for going out equipment initiation is really caused by triggering.Fig. 7 is the flow chart of the method for the invention.Specifically include as follows Step：

Step 701, UE sends NAS message request to eNodeB/RNC, and the instruction of UE applications triggers, the mark are carried in request It is to receive the NAS message request initiated after applications trigger to show UE；NAS message requests mainly include：Attach request, business At least one of request, position updating request, routing update request.

Step 702, NAS message request is forwarded to MME/SGSN by eNodeB/RNC, and UE applications triggers are carried in the message Instruction；

Step 703, MME/SGSN checks the NAS message request of UE, if it is the request received after applications trigger, MME/ SGSN further judges whether UE initiates NAS message request because of applications trigger according to the triggering information being locally stored, and in root It is judged that result determines that UE is that then MME/SGSN is according to migration efficiency pair when initiating NAS message request because of response application triggering The operation flow that UE is initiated is controlled, and specific strategy is：

MME/SGSN sends refuse information by eNodeB/RNC to UE, and suitable cause value is carried in message.

Step 704, if MME/SGSN can not judge UE is asked caused by whether really triggering according to locally store information, It can also apply judging to HSS/HLR by position updating request, may be selected to carry the instruction of UE applications triggers in the request message；

Step 705, HSS/HLR judges whether UE initiates to ask because of triggering, and lead to according to the triggering information locally preserved Cross location updating response and will determine that result is sent to MME/SGSN；

Step 706, the follow-up corresponding flow of NAS message request is performed；

Step 707a, deletes the information that the network preserved in MME/SGSN triggers UE.Such as：Timer can be set, and Deleted in timer expiry；Or when receiving the flow response of request, triggering information is deleted by MME/SGSN；

Step 707b, deletes the information that the network preserved in HSS/HLR triggers UE.Such as：Timer can be set, and Deleted during timer expiry.Or receive the notification message deletion triggering information of MME/SGSN；

Step 708, if MME/SGSN according to strategy (such as UE response applications trigger NAS message request allow the time In section but outside call duration time window；The non-emergent triggering of UE response applications) generate a call duration time window again for UE, then UE can be handed down to by NAS message response.MME/SGSN sends NAS message response to eNodeB/RNC, is taken in the response message With new call duration time window.

NAS responses mainly include：Attachment receive request, initialization context establish request, location updating received message and It route received message etc..

Step 709, eNodeB/RNC sends NAS message response to UE, and new call duration time is carried in the response message Window.The replaceable original time window of the call duration time window or the call duration time window to use temporarily.

Above-mentioned NAS message request may include at least one in attach request, service request, TAU requests, RAU requests Kind.
