Description
Technical Field
The present invention relates to a paging technology for a terminal device in mobile communication, and more particularly, to a method and an apparatus for optimizing paging.
Background
Mobile and broadband are The developing direction of modern communication technology, and The third generation Partnership Project (3 GPP), The 3rd generation Partnership Project, is dedicated to The evolution of 3G systems with The goal of developing 3GPP radio access technologies towards high data rate, low latency and optimized packet data applications. Long Term Evolution (LTE), a Long term evolution of the Universal Mobile Telecommunications System (UMTS) technology standard established by the 3GPP organization, is now well known and formally established and initiated at 3GPP multi-session at 12 months 2004.
The basic architecture of the LTE system mainly includes three parts: evolved UMTS Terrestrial Radio Access Network (E-UTRAN), Evolved packet Core Network (EPC), and User Equipment (UE). The E-UTRAN is an LTE access network, and is composed of a plurality of Evolved node bs (enbs); the EPC is a core network of LTE, and is composed of a Mobility Management Entity (MME), a Serving GateWay (SGW), and a packet data GateWay (PGW). The UE is interconnected with the eNB through a Uu interface, the eNB is interconnected with the EPC through an S1 interface, and the eNB is interconnected with the eNB through an X2 interface.
In the current network evolution, a large number of small base stations and home base stations are introduced, and the power consumption of the intelligent terminal is much larger than that of a common functional terminal, so that the time for the intelligent terminal to enter a sleep mode is required to be shortened in order to save power. However, when the intelligent terminal enters the sleep mode, the downlink data packet of the network cannot be directly sent to the intelligent terminal, but the MME is required to send a paging message to wake up the intelligent terminal from the sleep mode, so that the downlink data packet can be sent.
To implement the paging function, the LTE network may send a paging message to a UE in an IDLE state (IDLE) or a CONNECTED state (CONNECTED), that is: the MME issues the paging message through Tracking Area Identity (TAI) list information supported by the UE. Since the paging message is sent to the eNB by the MME and then related UEs are searched in the coverage of the eNB, the radio resources of the eNB are occupied. In order to improve the paging success rate and the service experience of the terminal user, the MME needs to send a large amount of paging messages to expand the paging range, however, the more paging messages the MME sends, the larger the paging range is, the more radio resources are consumed, and thus, the pressure on the network is increased; meanwhile, as various push services are more and more, a large amount of paging messages are sent to dormant intelligent terminals, if the push services are sent to high-density people in a stadium, for example, a signaling storm in an LTE/EPC network is likely to be induced, if the signaling storm is light, network element equipment is overloaded, and if the signaling storm is heavy, paralysis of the whole network is caused.

Here, the optimizing the cell range to which the paging message is issued within the determined range of the base station specifically means: and sending the paging message to one or more cells in the range of the base station where the UE to be paged is most probably located at present.
The following is a detailed description of a specific implementation process of the paging optimization method according to the embodiment of the present invention.
Example two:
fig. 2 is a schematic diagram of an interaction flow of a paging optimization method according to an embodiment of the present invention, and as shown in fig. 2, an implementation flow of the paging optimization method according to the embodiment of the present invention includes the following steps:
step 201: the UE reports the position information of the UE to be paged to the eNB, wherein the position information of the UE to be paged is carried in the TAU request message;
here, the location information of the UE to be paged, which is reported by the UE, is obtained, estimated, and reported by the UE itself.
The position information acquired by the UE is the position information of the UE in a certain time period; the position information of the UE in a certain time period is historical position information of the UE in a connected state and/or an idle state, and can be set arbitrarily according to the user requirements. In other words, the location information of the UE to be paged in the same time period is estimated according to the historical location information of the UE, and the estimation result is reported to the eNB.
Here, the UE positioning includes the following types: the first type is that Global Positioning System (GPS) positioning is realized by satellites, and the accuracy of the positioning mode is between 3 meters and 5 meters; the second type is that a base station network is used for rough positioning, which is called CELL IDentity (CELL IDentity) positioning, and compared with a GPS positioning mode, the positioning mode has smaller precision, and the general positioning error is 100 meters; the third type is Assisted Global Positioning System (AGPS) Positioning, which is a Positioning technology combining CELLID and GPS Positioning methods, and it is most accurate to perform UE Positioning using the Positioning method.
The UE can acquire historical position information of the UE in a connected state and/or an idle state in any positioning mode, wherein the historical position information comprises a moving route in a time period; determining a subsequent location after the user migration based on the historical location information and the data of the movement route; the post-migration subsequent location may include one or more location information. Specifically, the UE estimates the possible position of the UE at a certain time point by collecting the position information of the movement trajectory of the UE in a certain time period, analyzing a large amount of position information in the certain time period, and according to the big data analysis result, for example: the position information of the moving track of the user in a certain time, such as 24 hours, is collected, so that the actual position of the user at each time point in the time period is obtained, the possible position information of the user in the next 24-hour time period can be estimated accordingly, and the estimated position information is reported to the eNB.
Here, how to predict the possible location information of the user in the next 24-hour time period belongs to the prior art, and is not described in detail herein.
Here, the location information of the UE includes cell information of the UE in a connected state and/or an idle state, and the cell information includes but is not limited to: the cell information of the UTRAN system, the cell information of the GERAN system, the cell information of the LTE system and the cell information of the CDMA system, wherein the cell information comprises a cell global identifier.
It should be noted that due to the mobility of the UE, the called UE may be located anywhere in the network before communicating. The cellular mobile communication system initiates a call to an idle UE using a paging procedure. Based on the mobility management strategy controlled by the UE, the network is decided to know the position of the UE only in the TA level, therefore, when the network needs to page the UE, the paging message can be sent only on all cells in the whole TA level. Generally, a TA includes tens or even hundreds of cells, and obviously, sending the same paging message to all cells at the same time in the TA level consumes a large amount of air interface resources, so to avoid the above problem, it is necessary to reduce the number of cells sending pages as much as possible.
Step 202: the eNB reports the position information of the UE to be paged carried in the TAU request message to the MME;
here, in the connected state, the UE sends the location information to the MME, which means that the UE completes in the TAU procedure. In order to confirm the location of the mobile station, the network coverage area will be divided into several TAs, and when the UE moves from one TA to another TA, the location registration must be re-performed on the new TA to inform the network to change the stored mobile station location information, a procedure known as TAU. The TAU process in the idle state and/or the connection state is as follows:
in an idle state: the UE sends an RRC Connection Setup Complete (RRC Connection Setup Complete) message to the eNB, wherein the RRC Connection Setup Complete (RRC Connection Setup Complete) message comprises a Non-Access Stratum (NAS) TAU request message; carrying the position information of the UE in the TAU request message; the eNB selects an MME and sends an initialization UE MESSAGE (INITIAL UE MESSAGE) to the MME, wherein the initialization UE MESSAGE comprises a TAU request MESSAGE of an NAS layer; the MME acquires the location information of the UE.
In the connected state: in the Detach (Detach) process, the UE sends an uplink direct transfer (ULInformationTransfer) message to the eNB, wherein the ULInformationTransfer message comprises a TAU request message of an NAS layer; carrying the position information of the UE in the TAU request message; the eNB selects an MME and sends an UPLINK NAS TRANSPORT (UPLINK NAS TRANSPORT) message to the MME, wherein the message comprises a TAU request message of an NAS layer; the MME acquires the location information of the UE.
Step 203: and the MME optimizes the range of the issuing of the paging message according to the position information of the UE to be paged, which is reported by the eNB.
First, a corresponding relationship between the UE to be paged and the TA information, a corresponding relationship between the TA information and the base station, and a corresponding relationship between the base station and a cell under the jurisdiction need to be preset; determining the range of a base station to which the paging message needs to be sent according to the reported position information of the UE to be paged and each preset corresponding relation; then, optimizing the range of the cell to which the paging message is sent within the determined range of the base station.
Specifically, the MME analyzes a base station ID where the UE may currently reside, through the location information reported by the UE; the MME determines which eNB the paging information needs to be sent to, namely determines the range of the base station to which the paging information needs to be sent according to the TA information corresponding to the UE to be paged, the corresponding relation between the TA and the eNB, the corresponding relation between the eNB and the cell under jurisdiction and the analyzed ID of the base station where the UE possibly resides currently; then, the eNB determines the air interface of which cell the paging message needs to be sent at according to the received TA information corresponding to the UE to be paged and the corresponding relationship between the cells under the jurisdiction of each base station and the TA.
It should be noted that, according to the correspondence between the TA information and the base station and the correspondence between the base station and the cell under the jurisdiction, the correspondence between the cell under the jurisdiction of each base station and the TA information can be obtained.
Here, the optimizing the cell range to which the paging message is issued specifically includes: and sending the paging message to one or more cells in the range of the base station where the UE to be paged is most probably located currently.
Here, the paging message is transmitted to at least one base station within range of the determined base station in the form of an S1-AP message.
Example three:
as shown in fig. 3, the implementation procedure of the paging optimization method in the embodiment of the present invention includes the following steps:
step 301: acquiring the position information of UE to be paged from a position server;
here, according to the positioning function of the location server, the location of the UE to be paged can be positioned at any time, and the location information of the UE to be paged is acquired; the location server may also be used to store the location information of the UE, and the location server may be any one of a GPS server, a base station network location server, and an AGPS server, or any other server capable of storing location information.
Fig. 4 is a schematic diagram of a system structure corresponding to the paging optimization method in the embodiment of the present invention, and as shown in fig. 4, an a1 interface is an interface between a location server and an MME, that is: the location server is connected with the MME through an A1 interface, in other words, the MME acquires the location information of the UE to be paged from the location server through an A1 interface. The location information may be cell information where the UE currently resides; the cell information includes at least one of: cell information of UTRAN system, cell information of GERAN system, cell information of LTE system, cell information of CDMA system.
Here, the location server may perform coarse positioning, referred to as CELLID positioning, through the base station network to obtain the cell location information where the UE is currently located, and send the location information to the MME.
Step 302: and the MME determines the base station range to which the paging message needs to be issued according to the acquired position information of the UE to be paged, and optimizes the cell range to which the paging message is issued within the determined base station range.
Specifically, the MME analyzes the base station ID where the UE may reside currently according to the acquired location information of the UE to be paged; the method comprises the following steps that an MME determines which eNBs need to be sent by paging information according to preset TA information corresponding to UE to be paged, corresponding relation between the TA and the eNB, corresponding relation between the eNB and a cell under the jurisdiction and analyzed base station ID (identity) where the UE possibly resides currently, namely determines the range of the base station to which the paging information needs to be sent; then, the eNB determines the air interface of which cell the paging message needs to be sent at according to the received TA information corresponding to the UE to be paged and the corresponding relationship between the cells under the jurisdiction of each base station and the TA.
It should be noted that, according to the correspondence between the TA information and the base station and the correspondence between the base station and the cell under the jurisdiction, the correspondence between the cell under the jurisdiction of each base station and the TA information can be obtained.
Here, the optimizing the cell range to which the paging message is issued specifically includes: and sending the paging message to one or more cells in the range of the base station where the UE to be paged is most probably located currently.
Here, the paging message is transmitted to at least one base station within range of the determined base station in the form of an S1-AP message.
The UE paging optimization is realized through any one of the two realization schemes, the UE paging message issuing range can be optimized through the reporting of the paging optimization auxiliary information in the existing communication network and the complex small base station or home base station environment, the network performance is favorably improved, the phenomenon of overlarge wireless resource consumption can be avoided to a certain extent while the occurrence of signaling storm is prevented, and therefore the paging experience of a terminal user and the consumption of wireless resources are well balanced.
