Description

Method and device for generating and configuring mobility management parameters, SCOP and MME

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a method and an apparatus for generating and configuring mobility management parameters, an SCOP, and an MME.

Background

The 3rd Generation Partnership Project (3 GPP) organization initiated standard formulation work for two important projects, Long Term Evolution (LTE) and System Architecture Evolution (SAE), at stage R8 in order to enhance the competitive power of future networks. In terms of core networks, a completely new architecture of pure packet domain core networks was introduced, as shown in fig. 1.

The access network (E-UTRAN) in fig. 1 mainly implements a radio resource management function, and a corresponding network element is a base station (eNodeB). A Mobility Management Entity (MME) provides the main control for the LTE access network and is responsible for mobility management of the core network, including paging, security control, bearer control of the core network, and mobility control of the terminal in the idle state, etc. The serving gateway (S-GW) is responsible for the transfer, forwarding, and route switching of user plane data for user terminals (UEs), etc., and also serves as a mobility anchor for the user plane during inter-transfer between enodebs, as well as for LTE and other 3GPP technologies. The public data network gateway (P-GW) is a gateway facing a Public Data Network (PDN), and is mainly responsible for a packet filtering function based on a user, a lawful interception function, a protocol (IP) address allocation function of interconnection between networks of a UE, packet marking at an uplink and downlink transport layer, charging, gating, quality of service (QoS) control, bearer control, and the like. The Home Subscriber Server (HSS) is mainly responsible for subscription information management and authentication of the user. A Policy and Charging Rules Function (PCRF) is mainly responsible for policy charging and policy control for a user.

At present, LTE networks actually deployed by each operator are basically deployed according to the above architecture, and an individual operator may optionally deploy PCRF.

In order to ensure the normal and efficient operation of the network, various parameters need to be configured in network elements such as eNodeB, MME, S-GW, P-GW, HSS, PCRF and the like to ensure that each network element in the network can work cooperatively. These configuration parameters include the length of various timers, the size of various thresholds, the level of various priorities, various local control strategies, etc. These configuration parameters are currently statically configured locally on the network element or statically configured remotely through an Operation and Maintenance system (OAM), and most of them are configured at the network element level, and there are few parameters configured for individual users.

Therefore, the existing network element parameter configuration mode has certain limitations, for example, only static configuration is available, dynamic adjustment cannot be performed according to the running state of the network element, the number of users in the network, the user behavior, the user type, and the like, and different network element parameters cannot be configured for different users. Especially, for a UE with low mobility, the number of times for updating TAU in the periodic tracking area is too many, which results in low operating efficiency of the LTE network and waste of network resources.

Detailed Description

In order to make the technical problems, technical solutions and advantages of the present invention more apparent, the following detailed description is given with reference to the accompanying drawings and specific embodiments.

The invention provides various solutions for solving the problems that in the prior art, for a client UE with low mobility, the running efficiency of an LTE network is low and network resources are wasted due to the fact that the TAU is updated by a periodic tracking area for too many times, and the method comprises the following specific steps:

example one

As shown in fig. 2, a method for generating and configuring mobility management parameters in an embodiment of the present invention is applied to a core network self-configuration self-optimization platform SCOP, where the SCOP platform is connected to a network element in an Evolved Packet Core (EPC) network and/or connected to a data synthesis server in a unified Deep Packet Inspection (DPI) architecture, and the method includes:

step 21: acquiring a UE identifier of a client UE and a corresponding tracking area change frequency;

step 22: and if the change frequency of the tracking area is lower than a preset threshold value, sending a configuration message to a Mobility Management Entity (MME), wherein the configuration message is used for prolonging the Tracking Area Update (TAU) period of the UE corresponding to the UE identifier.

The configuration message may include the UE identity and corresponding TAU period modification information, such as which time period of the timer is modified, how long the time period is modified, and the like; the SCOP platform can be directly connected with a network element in an Evolved Packet Core (EPC) network or indirectly connected through an operation maintenance system (OAM).

In the method for generating and configuring mobility management parameters provided in the embodiment of the present invention, when the change frequency of the tracking area corresponding to the UE identifier is lower than the preset threshold, a configuration message is sent to the mobility management entity MME, where the configuration message is used to extend the tracking area update TAU period of the UE corresponding to the UE identifier, so that the MME can extend the TAU period of the corresponding UE according to the configuration message, and further correspondingly reduce the update frequency of the periodic tracking area of the UE with low mobility, thereby effectively reducing signaling, reducing network load, improving the operation efficiency of the LTE network, and saving network resources.

Wherein, the step of obtaining the UE identity of the client UE and the corresponding tracking area change frequency includes: receiving user signaling information of the UE reported by the MME; or, acquiring user signaling information of the UE from a data synthesis server in the DPI architecture, wherein the user signaling information of the UE includes a tracking area update signaling message of the UE; and counting the change frequency of the tracking area of the UE according to the tracking area update signaling message of the UE.

Specifically, the tracking area signaling message includes a periodic trigger and a trigger due to a tracking area change; the step of counting the change frequency of the tracking area of the UE according to the tracking area update signaling message of the UE comprises the following steps: and screening out tracking area updating signaling messages of the UE triggered by the change of the tracking area, and further counting to obtain the change frequency of the tracking area of the UE.

The tracking area signaling message corresponding to the above-mentioned content aware tracking area includes two TAU types, i.e., a periodic TAU and a list changed TAU; in practical applications, a UE needs to perform both periodic TAU and list changed TAU, but the trigger reasons are different, such as: the user brings the UE to shopping, a certain counter is just a critical point of two List lists, the UE instantly crosses the two List lists, and at the moment, the network needs to carry out TAU (task execution Unit) changing based on TA List on the UE; for another example: the user keeps the station with the UE still, and there is no way to trigger the TAU changed by the TA List, but the network needs to know the position of the UE to ensure that the UE receives the WeChat message and the short message, so the network can send the periodic TAU to the UE to acquire the position of the UE. The first trigger of TAU is location change, and the second trigger is that the timer set at the network side is overtime, and the network will actively make TAU.

Further, the method further comprises: and screening out the tracking area updating signaling message of the UE which is triggered periodically, and further obtaining the original TAU period information corresponding to the UE.

The original TAU period information is generally 54 minutes, but may be other values, and the present invention is not limited thereto.

Further, before the sending a configuration message to a mobility management entity MME if the tracking area change frequency is lower than a preset threshold, where the configuration message is used to extend a tracking area update TAU period of a UE corresponding to the UE identity, the method further includes: and judging whether the change frequency of the tracking area is lower than a preset threshold value or not.

In order to make the determination result more reasonable and reliable, before the determining whether the tracking area change frequency is lower than a preset threshold, the method further includes: and correspondingly setting the preset threshold according to the obtained UE identification and the corresponding original TAU period information.

In order to make the modified TAU period more practical and reasonable, if the tracking area change frequency is lower than a preset threshold, sending a configuration message to a mobility management entity MME, where the step of the configuration message for extending the tracking area update TAU period of the UE corresponding to the UE identity includes: and generating the configuration message according to the UE identification and the corresponding tracking area change frequency.

That is, the timer on the network side is extended by the change frequency corresponding to the TAU whose location is changed; such as: the motion trail of the UE is collected, and if the position of the UE is not changed from 8 am to 5 pm on the Internet on Monday to Friday, the periodic TAU time of the UE from 8 am to 5 pm is set to be 8 hours, and the rest time is still 54 minutes (the TAU period of the current network).

It should be noted that, the extending of the timer of the periodic TAU does not affect the network side to acquire the location information of the UE, because if the location of the UE changes, the TAU will still occur, but the TAU is changed based on the TA List.

Example two

As shown in fig. 3, a method for generating and configuring mobility management parameters in the second embodiment of the present invention is applied to a mobility management entity MME, and the method includes:

step 31: receiving a configuration message issued by a core network self-configuration self-optimization platform SCOP according to user signaling information of a client UE, wherein the configuration message is used for prolonging a tracking area update TAU period of the UE corresponding to a UE identifier in the user signaling information, and the SCOP platform is connected with a network element in an Evolved Packet Core (EPC) network and/or a data synthesis server in a unified Deep Packet Inspection (DPI) architecture;

step 32: and modifying the TAU period of the corresponding UE according to the configuration message.

The method for generating and configuring the mobility management parameters provided in the second embodiment of the present invention receives the configuration message issued by the network self-configuration self-optimization platform SCOP according to the user signaling information of the client UE, and extends the TAU period of the corresponding UE according to the configuration message, so that the update frequency of the periodic tracking area of the UE with low mobility is correspondingly reduced, and thus the signaling can be effectively reduced, the network load can be reduced, the LTE network operation efficiency can be improved, and the network resources can be saved.

Further, before the receiving a configuration message issued by the core network self-configuration self-optimization platform SCOP according to the user signaling information of the client UE, the method further includes: and reporting user signaling information of the UE to the SCOP platform, wherein the user signaling information of the UE comprises a tracking area updating signaling message of the UE.

In addition, after the modifying the TAU period of the corresponding UE according to the configuration message, the method further includes: and performing TAU on the corresponding UE according to the modified TAU period.

Considering an actual application scenario, after the modifying the TAU period of the corresponding UE according to the configuration message, the method further includes: and sending the configuration message to a base station, so that the base station modifies the TAU period of the corresponding UE according to the configuration message, and performs TAU on the corresponding UE according to the modified TAU period.

It should be noted that, the TAU period (timer of periodic TAU) of the UE is extended, and does not affect the network side to acquire the location information of the UE, because if the location of the UE changes, the TAU will still occur, but the TAU is changed based on the TA List.

EXAMPLE III

The method for generating and configuring the mobility management parameters provided by the third embodiment of the present invention is summarized as follows:

the SCOP collects signaling information of a user from the MME, such as a user identifier, a user location, a user TAU frequency, and the like, or receives all user signaling information and data plane information in the EPC network from a data synthesis server in the unified DPI architecture, and counts the mobility rule of the user according to the collected information, thereby generating a suitable network configuration parameter to be issued to the MME, and to be issued to the eNodeB through the MME, where the specific flow is shown in fig. 4:

step 41: the MME reports signaling information of the user, including a tracking area update signaling message of the UE, that is, a tracking area update TAU type (periodicity, TA List tracking area List change, etc.) and location change content.

Step 42: SCOP counts the TAU type and frequency of the user, and sets a certain threshold value by combining with the traffic model, if the frequency of the TAU type related to the position movement (TA List change) is lower, the mobility of the user is lower, the SCOP generates configuration information and sends the configuration information to MME so as to inform the MME to prolong the TAU period of the user.

There are many data in the traffic model, such as the period of TAU and the timing time of the release of the user S1 interface, but here, the period of TAU is used, that is, 54 minutes used in the current network, which is a statistical value, and a guiding value obtained after counting the characteristics of many users' movements. The traffic model is a collection of such statistics.

The threshold value here is preferably set to a value corresponding to the TAU period; the configuration message may include the UE identity and corresponding TAU period modification information, such as which time period timer was modified, how long it was modified, etc.

Step 43: and the MME prolongs the period of the periodic TAU of the user according to the configuration information and performs corresponding TAU according to the modified TAU period.

Step 44: and the MME transmits the configuration information to the base station, so that the base station prolongs the period of the corresponding user periodic TAU according to the configuration information and performs the corresponding TAU according to the modified TAU period.

The scheme provided by the third embodiment of the invention can effectively reduce signaling and reduce network load by SCOP statistics and user-specific TAU period setting.

The SCOP mentioned in all the above embodiments is described in detail below.

As shown in fig. 7, the SCOP is divided into three layers: interface layer, intermediate processing layer, application layer (APP layer). Wherein, the three layers are responsible for the following main functions:

interface layer: the interface layer is responsible for connecting with each network element in the EPC network and the unified DPI platform, and performs link management such as link establishment and deletion, collection of network element information and user signaling information data plane information, and issuing of network configuration parameters.

The intermediate processing layer is responsible for preprocessing the information received by the SCOP, for example, filtering out user signaling in the range of a normal traffic model, and only sending users and signaling thereof outside the normal traffic model to the APP layer. The intermediate processing layer is also responsible for receiving the network configuration parameters from the APP layer, transmitting the network configuration parameters to the interface layer, and sending the network configuration parameters to the specific network element by the interface layer.

The application layer receives the network element information and the user signaling information data plane information from the intermediate processing layer, deduces network configuration parameters which enable the network to be optimal through a proper algorithm, and sends the network configuration parameters to the intermediate processing layer.

The interface between the application layer and the intermediate processing layer, namely the API1, can use an interface mode of a Restful architecture, and the format of interface messages is fixed, so that a third party can develop an APP as required.

In addition, the SCOP platform is used as a network element of the EPC network, and the relationship diagram of the SCOP platform and other existing network elements is shown in FIG. 8. The network element and the EPC network have network elements (eNodeB-base station, base transceiver station of BTS/NodeB-2G network/base transceiver station of 3G network, BSC/RNC-base station controller/radio network controller, MME/SGSN-mobility management entity/service GPRS support node, SAE GW/GGSN-SAE gateway/gateway GPRS support node, PCRF-policy and charging execution function unit, wherein SAE GW includes S-GW and P-GW) directly connected or transferred through OAM system (for example, eNodeB is connected with wireless OAM system, and wireless OAM system is connected with SCOP). The interface protocol of SCOP and each network element can adopt diameter, SOAP or other self-defined protocol. In addition, the SCOP can also be connected with a data synthesis server in the unified DPI architecture.

It should be noted that many of the functional components described in this specification are referred to as modules/sub-modules in order to more particularly emphasize their implementation independence.

In embodiments of the invention, the modules/sub-modules may be implemented in software for execution by various types of processors. An identified module of executable code may, for instance, comprise one or more physical or logical blocks of computer instructions which may, for instance, be constructed as an object, procedure, or function. Nevertheless, the executables of an identified module need not be physically located together, but may comprise disparate instructions stored in different bits which, when joined logically together, comprise the module and achieve the stated purpose for the module.

Indeed, a module of executable code may be a single instruction, or many instructions, and may even be distributed over several different code segments, among different programs, and across several memory devices. Likewise, operational data may be identified within the modules and may be embodied in any suitable form and organized within any suitable type of data structure. The operational data may be collected as a single data set, or may be distributed over different locations including over different storage devices, and may exist, at least partially, merely as electronic signals on a system or network.

When a module can be implemented by software, considering the level of existing hardware technology, a module implemented by software may build a corresponding hardware circuit to implement a corresponding function, without considering cost, and the hardware circuit may include a conventional Very Large Scale Integration (VLSI) circuit or a gate array and an existing semiconductor such as a logic chip, a transistor, or other discrete components. A module may also be implemented in programmable hardware devices such as field programmable gate arrays, programmable array logic, programmable logic devices or the like.

While the preferred embodiments of the present invention have been described, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention.
