Description
Technical Field
The present invention relates to a setting technique of a periodic timer, and in particular, to a method and a system for setting a periodic timer.
Background
Fig. 1 is a schematic diagram of an EPS system and an access network architecture in the prior art, and as shown in fig. 1, an Evolved Packet System (EPS) in the third generation partnership project (3 GPP), which is composed of an evolved universal mobile telecommunications system terrestrial radio access network (E-UTRAN), an evolved universal terrestrial radio access network (evolved universal terrestrial radio access network), a mobility management unit (MME), a serving gateway (S-GW, serving gateway), a packet data network gateway (P-GW, packet data networking gateway), a Home Subscriber Server (HSS), a policy and charging rules function entity (PCRF), a policy and charging rules function AAA, and other support nodes such as a 3GPP Authentication Authorization account (Authentication, Authorization, and Accounting server). The core network part in EPS is called packet core evolution (EPC, EvolvedPacketCore).
The MME is responsible for the related work of control planes such as mobility management, management of user mobility management context such as mobility management state and user security parameters, processing of non-access stratum signaling and the like; the S-GW is an access gateway device connected with the E-UTRAN, forwards data between the E-UTRAN and the P-GW, and is responsible for caching paging waiting data; the P-GW is a border gateway of the EPS and a Packet Data Network (PDN) and is mainly responsible for accessing the PDN, forwarding data between the EPS and the PDN and the like; the PCRF is a policy and charging rule function entity, and is connected to an operator network protocol (IP) service network through an Rx interface to obtain service information, and is also connected to a P-GW through a Gx interface, connected to a trusted non-3 gpp IP access network through a Gxa interface, and connected to an S-GW through a Gxc interface, and is responsible for initiating establishment of an IP bearer, ensuring quality of service (QoS) of service data, and performing charging control.
Fig. 2 is a system architecture diagram of a UTMS in the prior art, and as shown in fig. 2, a universal mobile telecommunications system (UTMS) network is composed of a universal mobile telecommunications system terrestrial radio access network (UTRAN), a Serving GPRS Support Node (SGSN), a GPRS Gateway Support Node (GGSN), and a Home Location Register (HLR). The SGSN has a function of routing and forwarding a packet data packet of a terminal in a service area of the SGSN, and a function of performing mobility management and the like for the terminal. The GGSN provides routing and encapsulation of data packets between the GPRS network and external data networks. The PDN is a network that provides services to users. The HLR is used for storing the subscription data of the user. The SGSN and the UTRAN use Iu-PS interface communication, and the SGSN completes the communication with the UTRAN system and the terminal through the interface, so as to complete the functions of packet data transmission, mobility management, session management and the like. The establishment, release and control of the IP channel are completed between the SGSN and the GGSN through a Gn interface. The SGSN retrieves data about the terminal from the HLR, which holds GPRS subscriber data and routing information, via the Gr interface. The Gi interface is the interface between GPRS and the external PDN. GPRS is interconnected with various public packet networks (e.g., Internet or Integrated Services Digital Network (ISDN)) through a Gi interface, and the Gi interface needs to perform operations such as encapsulation/decapsulation of protocols, address conversion (e.g., converting private network IP addresses into public network IP addresses), authentication and authentication when a user accesses.
The narrow definition of M2M (MachinetoMachine) is machine-to-machine communication. The broad definition is networked applications and services with machine terminal intelligent interaction as core. The intelligent machine terminal is based on an intelligent machine terminal, various communication modes are used as access means, an informatization solution is provided for a client, and the intelligent machine terminal is used for meeting informatization requirements of the client on monitoring, commanding and scheduling, data acquisition, measurement and the like.
The development of the wireless technology is an important factor for promoting the development of the M2M market, and the wireless technology breaks through the space-time limitation and the geographical barrier of the traditional communication mode, so that enterprises and the public get rid of the cable constraint, the cost can be more effectively controlled, the installation cost is reduced, and the use is simple and convenient. In addition, the increasing demand pushes M2M to move forward, but in contradiction to the increasing information processing capability and network bandwidth, the means for information acquisition is far behind. The M2M well meets the requirement of people, and people can monitor the external environment in real time through the M2M, so that large-scale and automatic information acquisition is realized. Thus, M2M may be applied to industrial applications, home applications, personal applications, and the like. Industrial applications are as follows: traffic monitoring, alarm systems, rescue at sea, vending machines, driving payment, etc. Household applications are as follows: automatic meter reading, temperature control and the like. Personal applications such as: life detection, remote diagnostics, etc.
In M2M applications, a considerable number of Machine Type Communication (MTC) devices are devices with low mobility characteristics, and some devices, such as meter reading, vending machines, etc., are fixed without moving for a certain time. If these devices perform mobility management according to the original method, resources are wasted. In addition, the power saving characteristic is also a basic requirement of the MTC equipment, but frequent mobility management causes unnecessary power loss.
Currently, the timer of the SGSN/MME includes: periodic tracking area update timer, unreachable timer, delete user data timer. The duration of the periodic tracking area update timer is unique in the routing area, and the duration is sent to the terminal in a Routing Area Update (RAU) response or an attach response message. The value of the timer is sent by the SGSN/MME to each User Equipment (UE) registered therein. When the timer is overtime, the UE initiates periodic tracking area update. When the unreachable timer times out, the SGSN/MME clears the Paging Proceed Flag (PPF). Typically, in GPRS, the SGSN stops sending GPRS paging or CS paging messages. When the next active behavior of the terminal is detected, the PPF is reset. A mobility management and Packet Data Protocol (PDP) context needs to be saved in the SGSN. And when the timer for deleting the user data is overtime, the SGSN/MME deletes the mobility management and the PDP context of the UE, wherein the timer for deleting the user data is set by the network according to a network operation strategy.
For the characteristics of M2M application, there is a scheme called periodic location update timing time at HSS signed MTC device, which is issued to SGSN/MME for execution in the attach process. If HSS updates timer, network initiates detachment to current MTC device, and carries reattachment indication, requiring MTC device reattachment. This solution solves the problem that the network can tailor different location update times for different characteristics of the MTC devices. Fig. 3 is a flowchart illustrating an MME customizing mtue periodic routing area/tracking area update timer time in the prior art, and as shown in fig. 3, the flowchart specifically includes the following steps:
step 301: the MTCUE transmits an attach request to a base station (eNodeB);
step 302: the eNodeB sends an attachment request to the MME;
step 303: MME sends a location update request to HSS;
step 304: the HSS sends a location update response to the MME, wherein the response carries the relevant information of the periodic tracking area update timer of the MTCE;
step 305: MME sets a periodic tracking area update timer of MTCE, and the time value of the periodic tracking area update timer is a subscription value downloaded from HSS;
step 306: and finishing the subsequent process of the attachment flow.
However, the above solution is to configure the timer at the home, but in the roaming scenario, the timer is executed at the MME at the roaming location, so that such setting may cause that the time for configuring the timer at the home may not be consistent with the visited policy. And there is a certain association between the timers to which the mobility management network element belongs, for example, the set time of the unreachable timer is longer than that of the periodic routing area/tracking area update timer, and the timer for deleting the user data is started after the unreachable timer is overtime. If only the time of the periodic routing area/tracking area update timer is set, and the relationship between the timers is not considered, a system error may be caused: for example, if the tracking area update time is not reached and the unreachable timer times out, the system sets the user to unreachable, and so on.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail below with reference to the accompanying drawings by way of examples.
First, the periodic timer of the present invention will be briefly described below. The periodic timer in the present invention includes: periodic routing area/tracking area update timers, unreachable timers and delete user data timers. The basic idea of the present invention is to set a level of a periodic timer at the network side, which is determined according to the attribute information of the mtue, specifically, the attribute of the mtue includes whether the mtue is a mobile terminal, if it is a fixed terminal, the timer duration is set longer; if the mobile terminal is a mobile terminal, the time length of the timer is set to be shorter, and for example, for a terminal with basically no mobility of equipment such as an electric meter, a water meter and the like in a meter reading system, the time length of the timer is set to be relatively longer, and for a mobile device such as a vehicle-mounted device, the time length of the timer is set to be relatively shorter. In this way, different periodic timer levels may be set according to the type of MTCUE. The invention sets the level and sets the time length relationship among the periodic routing area/tracking area updating timer, the unreachable timer and the user data deleting timer, for example, in the periodic routing area/tracking area updating timer value of the same level, the time length of the unreachable timer is longer than that of the periodic routing area/tracking area updating timer. Specifically, the respective rank periodic timer values of the mtciue may be set in the manner shown in table 1 below:
TABLE 1
In table 1 above, the rank of the periodic timer is set according to the attributes of the mtue, for example, two ranks in table 1 are set according to the attributes of the fixed terminal and the mobile terminal, but of course, other ranks may be set according to other attributes of the mtue. In each level, the values of the periodic timers are determined, that is, the timers 11 to 31 and the timers 12 to 32 all represent specific durations, wherein the duration of the unreachable Timer in each level is greater than the duration of the periodic position updating Timer.
The method for configuring the periodic timer value is not limited, and other times may be calculated from one of the times. For example, if it is known that the periodic routing area/tracking area update Timer value corresponding to level 1 is Timer11, the unreachable Timer21 is Timer11+ m, and the delete user data Timer31 is Timer11+ n.
The essence of the present invention will be further described below with reference to specific embodiments.
Example one
The application scenario of this embodiment is that a user database signs a periodic timer level of mtue, when the mtue is attached, the user database issues the periodic timer level to a mobility management network element, the mobility management network element determines a time length of a periodic routing area/tracking area update timer, an unreachable timer, and a user data timer deletion according to the periodic timer level, and the mobility management network element sets a timer related to MTC devices according to the time length of the timer. Fig. 4 is a flowchart of a first embodiment of a method for setting a periodic timer according to the present invention, and as shown in fig. 4, the method for setting a periodic timer specifically includes the following steps:
step 401: the mtcu sends an attach request to an eNodeB/Radio Network Controller (RNC); the request is attached to the eNodeB. The attach request carries mtue attribute information, such as mtue identification information, device model or type, and the like.
Step 402: the eNode/RNC sends an attachment request to a mobility management network element; after receiving the attach request of the mtcu, the eNode/RNC forwards the attach request to a mobility management element, i.e., MME/SGSN.
Step 403: the mobile management network element sends a position updating request to a user database; after receiving the attachment request of the MTCU forwarded by the eNode/RNC, the mobility management network element sends a location updating request to a user database to acquire related subscription information of the MTCU, so as to further determine the time length of a periodic routing area/tracking area updating timer, an unreachable timer and a user data deleting timer of the MTCU according to the periodic timer grade in the related subscription information of the MTCU.
Here, the subscriber database is provided in the HSS or HLR on the network side, i.e. stored in the network element as the subscriber subscription information.
Step 404: the user database sends a location update response to the mobility management network element, wherein the response carries the periodic timer grade of the MTCE; here, the user database does not directly return the time length information of the periodic routing area/tracking area update timer, the unreachable timer and the delete user data timer to the mobility management network element, but returns the signed periodic timer level information to the mobility management network element.
Step 405: the method comprises the steps that a mobility management network element determines a periodic routing area/tracking area updating timer, an unreachable timer and the time length for deleting a user data timer of the MTCE corresponding to the periodic routing area/tracking area updating timer and the unreachable timer of the MTCE according to the periodic timer grade of the MTCE, and sets the periodic routing area/tracking area updating timer of the MTCE according to the determined time length; here, since the mobility management network element stores the periodic timer level and the corresponding time length information of the periodic routing area/tracking area update timer, unreachable timer and delete user data timer, after the level information is determined, the time lengths of the three timers can be determined.
Step 406: and issuing the periodical routing area/tracking area updating timer of the MTCE to the MTCE in the response flow of the attachment flow.
In this embodiment, since the time length information of the periodic routing area/tracking area update timer, the unreachable timer, and the delete user data timer at each level is set in advance, the time length configuration of each timer is configured strictly according to the advance requirement, and the conflict caused by the mismatch of the time length configuration of the timers is solved before the configuration.
Thus, even if the MTCU is in a roaming state, the corresponding mobility management network element can determine the time length of the periodic routing area/tracking area updating timer, the unreachable timer and the user data deleting timer of the MTCU according to the acquired periodic timer grade of the MTCU, so that the configuration of the timers is completely consistent with that in a non-roaming state.
Example two
In an application scenario of this embodiment, the mobility management element pre-configures periodic timer information, which includes the time length information of the periodic routing area/tracking area update timer, unreachable timer, and user data deletion timer at each level. And the mobility management network element determines the grade of the periodic timer according to the MTCE attribute reported by the MTCE or the signed MTCE attribute information in the user database, thereby determining the MTCE periodic timer, namely the periodic routing area/tracking area updating timer, the unreachable timer and the time length for deleting the user data timer. Or, the mobility management network element determines the unreachable timer and the time length for deleting the user data timer according to the time length of the periodic routing area/tracking area updating timer issued by the user database. Fig. 5 is a flowchart of a second embodiment of the method for setting the periodic timer according to the present invention, and as shown in fig. 5, the method for setting the periodic timer specifically includes the following steps:
step 501: the MTCUE sends an attachment request to the eNodeB/RNC, and the request message carries MTCUE attribute information. The attribute information is the attribute that the mtce ue can report, such as whether the mtce ue is in a power saving state, a device type (mapinetype), and the like.
Step 502: the eNode/RNC sends an attachment request to a mobility management network element; this step is the same as step 402.
Step 503: the mobile management network element sends a position updating request to a user database; this step is the same as step 403.
Step 504: the user database sends a location updating response to the mobility management network element, wherein the response carries the periodic routing area/tracking area updating timer information of the MTCE and/or the attribute information of the MTCE; the attribute information here is attribute information of an mtue subscription.
Step 505: the method comprises the steps that a mobility management network element determines a periodic timer grade according to MTCE attribute information reported by MTCE or MTCE attribute information signed by the MTCE, and determines a periodic routing area/tracking area updating timer, an unreachable timer and the time length for deleting a user data timer of the MTCE corresponding to the grade according to the periodic timer grade of the MTCE; or, when the location update response sent by the user database to the mobility management element directly carries the periodic routing area/tracking area update timer information, such as the time length of the periodic routing area/tracking area update timer, the mobility management element matches the periodic routing area/tracking area update timer in each level of the periodic timers stored in the mobility management element according to the time length information of the periodic routing area/tracking area update timer, that is, the periodic routing area/tracking area update timer level corresponding to the time length is matched in table 1, so as to determine the unreachable timer corresponding to the level and the time length of the user data deletion timer, and set the unreachable timer and the user data deletion timer according to the determined time length; and setting a periodic routing area/tracking area update timer of the mtue for the determined duration.
Step 506: and issuing the periodical routing area/tracking area updating timer of the MTCE to the MTCE in the response flow of the attachment flow.
