Detailed Description
The following describes specific embodiments of the present invention in detail with reference to the drawings. It should be understood that the detailed description and specific examples, while indicating and illustrating the invention, are not intended to limit the invention. It will be apparent to one skilled in the art that the present invention may be practiced without some of these specific details. The following description of the embodiments is merely intended to provide a better understanding of the invention by showing examples of the invention.
It should be noted that, in this document, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising … …" does not exclude the presence of other like elements in a process, method, article, or apparatus that comprises an element.
Typical circuit switched fallback (Circuit Switched Fallback, CSFB) traffic flows mainly include joint attach, location update, caller (Mobile Origination Call, MO) CSFB flow, callee (Mobile Termination Call, MT) CSFB flow, detach, etc. The attachment procedure of the mobile terminal of the CSFB-enabled subscriber is based on a joint GPRS/international mobile subscriber identity (International Mobile SubscriberIdentification Number, IMSI) attachment procedure.
The multimode single standby handheld terminal carries an indication of supporting CSFB capability in an attach request message sent to the MME. After receiving the combined attachment request of the user, the MME performs the attachment of the evolved packet system (Evolved Packet System, EPS), deduces the information of the visitor location register (VisitedLocation Registor, VLR) of the related Circuit Switched (CS) domain, and initiates a location update request to the VLR, and after receiving the location update request, the VLR marks the user as having performed the attachment of the EPS and saves the Internet protocol (Internet Protocol, IP) address of the MME of the user,
thus, the VLR creates SGs association between the VLR and MME of the user. Wherein, the liquid crystal display device comprises a liquid crystal display device,
the SGs interface is the interface between MSC/VLR and MME through which the joint attach function can be implemented.
The MSC Server/VLR then performs CS domain location update and passes the temporary Mobile subscriber identity (Temporary Mobile Subscriber Identity, TMSI) and LAI (location area identity) of the subscriber to the MME, thereby establishing SGs association in the MME. Finally, the MME includes TMSI and LAI information allocated to the user by the VLR in an attach request acceptance message and sends the information to the UE, and then the combined attachment of the user is indicated to be successful. After the joint attachment is successful, the CSFB-capable user can process the circuit-domain service in the LTE network.
In the EPS system, in order to reduce air interface signaling between the UE and the core network, a function of ISR (Idle mode Signaling Reduction) is introduced. When this functionality is activated, a mobile terminal (UE) having both evolved universal terrestrial radio access network (Universal Terrestrial Radio Access Network) UTRAN/radio access network (GSM EDGE Radio Access Network, GERAN) and evolved UMTS terrestrial radio access network (Evolved UMTS Terrestrial Radio Access Network, E-UTRAN) access functionality may register with both MME and general packet radio service (General Packet Radio service, GPRS) serving support node (Serving GPRS Support Node, SGSN). In this way, when the UE moves under two different access networks, the UE does not initiate a routing area update (Routing Area Update, RAU) or a tracking area update (Tracking Area Update, TAU) across radio access technologies (Inter Radio Access Technology, inter RAT), thereby reducing unnecessary signaling.
At present, a mobile terminal with ISR capability is firstly combined attached on a fourth generation mobile information system (The 4th Generation Mobile Communication Technology,4G) network, ISR is not activated at this time, when The mobile terminal moves to The edge of a 4G network coverage area and The coverage area of a 2G/3G network, the mobile terminal resides in The 2/3G network, if The LAI of a mobile terminal resident 2G/3G network cell is The same as The combined attached LAI, the mobile terminal does not perform location update (Location Area Update, LAU), MSC does not delete SGs interface, the mobile terminal performs RAU, SGSN sends context request information to MME after receiving RAU request, and after receiving The context response information of The MME, SGSN sends routing area update (Routing Area Update, RAU) acceptance information including ISR activation indication to The mobile terminal. When the mobile terminal has an incoming call, the MSC sends a paging request to the MME, the MME pages within the TAI list of the mobile terminal and sends the paging request to the SGSN, the SGSN pages within the RAI range, and after receiving the paging request of the SGSN, the mobile terminal is connected to the MSC to perform paging response to establish a call.
For a better understanding of the present invention, the active paging method according to embodiments of the present invention will be described in detail below with reference to the accompanying drawings, and it should be noted that these embodiments are not intended to limit the scope of the present disclosure.

and S130, before the timer is overtime, if the mobile terminal has an incoming call, the mobile terminal preferentially pages in the range of the location area indicated by the location area identification of the mobile terminal.
According to the method for activating paging provided by the embodiment of the invention, after the MSC receives the mobile terminal ISR activation information sent by the MME, if the mobile terminal is judged to activate the ISR in the home network, the MSC starts a timer, the time length is the same as that of the periodic LAU, and the paging is preferentially carried out on the LAI when the call comes before the time-out of the timer, instead of sending a paging request to the MME, the paging request is prevented from being carried out in two networks, so that air interface resources are saved, the interactive information between network devices is reduced, and the paging activating efficiency is improved.
In some embodiments, before the timer expires, activating the paging method further comprises: s11, if the mobile terminal does not respond, the paging request is directly sent to the MME.
In the embodiment, when the timer is overtime and has an incoming call, the LAI is preferentially paged, and if the mobile terminal does not respond to the paging, the mobile terminal sends the paging to the MME, so that the air interface resource can be saved, the interactive information between network devices can be reduced, and the paging activating efficiency can be improved.
In some embodiments, before the timer expires, activating the paging method further comprises: s21, if a position update request of the MME is received, closing a timer; s22, when the mobile terminal has an incoming call, the paging request is directly sent to the MME.
In the step, MSC receives the position update of MME before the timer overtime and then closes the timer, and when the timer comes, the MSC directly sends paging to the MME to avoid the paging request to be carried out in two networks, thereby saving air interface resources, reducing the interaction information between network devices and improving the paging activating efficiency.
In some embodiments, before the timer expires, activating the paging method further comprises: s31, deleting an SGs interface under the condition that the periodical tracking area update TAU timer is overtime and a position update request of the mobile terminal is received, so that the mobile terminal activates ISR; s32, if the mobile terminal has an incoming call, the mobile terminal is directly paged on the 2G/3G network.
In this step, if the periodic TAU timer expires before the timer expires, the mobile terminal performs LAU, the MSC deletes the SGs interface, and the mobile terminal deactivates the ISR. When there is an incoming call, MSC directly pages the mobile terminal on the 2/3G network. Therefore, the paging request can be prevented from being carried out in two networks, the air interface resources are saved, the interactive information between network devices is reduced, and the paging activating efficiency is improved.
In some embodiments, after the timer expires, activating the paging method further comprises: s41, if the mobile terminal has an incoming call, the mobile terminal directly sends a paging request to the MME, and informs the MME that the paging request does not need to be sent to the SGSN.
In the step, MSC directly sends paging request to MME when timer has time out, and informs that it is not necessary to send paging request to SGSN, so as to avoid paging request in two networks, save air interface resource, reduce interactive information between network devices, and improve paging activating efficiency.
According to the method for activating paging in the embodiment of the invention, after the MSC receives the mobile terminal ISR activation information sent by the MME, the MSC judges that the mobile terminal activates the ISR in the home network, the MSC starts a timer, the time length is the same as that of the periodic LAU, and when the timer is overtime and has an incoming call, the MSC preferentially carries out paging in the LAI, and if the timer does not respond, the MSC sends paging to the MME. The MSC receives the position update of the MME before the timer is overtime, then closes the timer, and directly sends paging to the MME when the call comes. If the periodic TAU timer times out the mobile terminal to carry out LAU before the timer times out, the MSC deletes the SGs interface, and the mobile terminal deactivates the ISR. When there is an incoming call, MSC directly pages the mobile terminal on the 2/3G network. MSC directly sends paging request to MME when timer has expired, and informs that it is not necessary to send paging request to SGSN, so as to avoid paging request in two networks, save air interface resource, reduce interactive information between network devices, and improve paging activating efficiency.

In some embodiments, the paging module 230 is further configured to send a paging request directly to the MME and notify the MME that the paging request does not need to be sent to the SGSN if the mobile terminal has an incoming call after the timer expires.
According to the storage controller MSC provided by the embodiment of the invention, after receiving the mobile terminal ISR activation information sent by the MME, if the mobile terminal is judged to activate the ISR in the home network, the MSC starts a timer, the time length is the same as that of the periodic LAU, and the paging is preferentially carried out on the LAI when the incoming call is made before the time-out of the timer, instead of sending a paging request to the MME, so that the paging request is prevented from being carried out in two networks, thereby saving air interface resources, reducing the interaction information between network devices and improving the activation paging efficiency.
The method for activating paging and the storage controller MSC can optimize ISR activating paging. Illustratively, the mobile terminal is a 4G multimode card and selects CSFB technology to enable voice call.
When the mobile terminal is started, the combined attachment flow of the 4G multimode card is started, the 4G multimode card sends a combined attachment message to the MME, the MME sends a position update request to the MSC, and the VLR sends a 4G multimode card position update flow to the HLR.
After the joint attachment flow is finished, when the mobile terminal moves to the coverage edge of the 4G network and the coverage area of the 2G/3G network, the mobile terminal resides in the 2G/3G network, if the LAI of the mobile terminal in the 2G/3G network cell is the same as the LAI of the joint attachment, the mobile terminal does not carry out LAU, the MSC does not delete SGs interface, the mobile terminal carries out RAU, the SGSN sends context request information to the MME after receiving the RAU request, the MME sends a request for inquiring the SGs interface state of the mobile terminal to the MSC, the MSC returns the SGs interface state of the mobile terminal, the MME sends context response information to the SGSN and comprises ISR activation indication, and the SGSN sends the context response information to the MME to make ISR activation clear.
After receiving the ISR activation information, the MME sends mobile terminal ISR activation information to the MSC, including mobile terminal identification, ISR activation and network information where the ISR activation resides.
After receiving the ISR activation information of the mobile terminal sent by the MME, the MSC judges that the mobile terminal activates the ISR in the home network, the MSC starts a timer, the duration of the timer is the same as the duration of the periodic LAU, and the mobile terminal is preferentially paged in the LAI when the time of the timer is over, if the mobile terminal does not respond, the mobile terminal sends paging to the MME. The MSC closes the timer after receiving the position update of the MME before the timer is overtime, and directly sends paging to the MME when the call comes. If the periodic TAU timer times out the mobile terminal to carry out LAU before the timer times out, the MSC deletes the SGs interface, and the mobile terminal deactivates the ISR. When there is an incoming call, MSC directly pages the mobile terminal on the 2G/3G network. The MSC directly sends a paging request to the MME when the timer expires, and notifies that the paging request does not need to be sent to the SGSN.
Through the processing flow, the paging request can be prevented from being carried out in two networks, so that air interface resources are saved, interaction information among network devices is reduced, and paging activating efficiency is improved.

In some embodiments, the mobile terminal may be a fourth generation mobile information system (The 4th Generation Mobile Communication Technology, 4G) multimode card, and The 4G multimode card selects CSFB technology to enable voice calls. The specific flow of the method for activating paging in the embodiment of the invention is as follows:
s301, after the mobile terminal is started, starting a joint attachment flow of the 4G multimode card.

In this step, the location update request message includes parameters such as a new location area identifier (Location Area Identify, new LAI), IMSI of the 4G multimode card, MME identifier (MME Name), and location update type (Location Update Type).
S303, the VLR stores MME information and creates SGs association with 4G multimode cards under the MME.
S304, the VLR initiates a 4G multimode card position updating flow of the HLR according to the user information and the position area information.
S305, the VLR returns confirmation information to the MME.
S306, the MME sends an Attach Accept (Attach Accept) message to the mobile terminal to complete the joint attachment.
S307, when the mobile terminal moves to the coverage edge of the 4G network and the coverage of the 2G/3G network, the mobile terminal resides in the 2G/3G network.
In the embodiment of the invention, if the LAI of the mobile terminal resident in the 2G/3G network cell is the same as the jointly attached LAI, the mobile terminal does not carry out LAU, and the MSC does not delete the SGs interface.

S312, the MME sends context response information to the SGSN, including an ISR activation indication.
S313, the SGSN sends context response information to the MME to determine ISR activation.
S314, after receiving the ISR activation information, the MME sends the mobile terminal ISR activation information to the MSC.
The activation information includes: mobile terminal identification, ISR activation and network information on which it resides at the time of activation.
S315, after receiving the mobile terminal ISR activation information sent by the MME, if the mobile terminal is judged to activate the ISR in the home network, the MSC starts a timer, and the duration of the timer is the same as the duration of the periodic LAU.
Through the steps S301-S305, the mobile terminal interacts with the network side, and completes the attachment flow and the ISR activation flow of the mobile terminal, the MSC determines that the mobile terminal starts a timer under the condition that the ISR is activated by the home network, and the duration of the timer is the same as the duration of the periodic LAU, so as to be used in the subsequent processing flow of the active paging method of the present invention.
In the subsequent processing flow of the paging activation method, before the timeout of the timer, when the mobile terminal has an incoming call, the MSC preferentially carries out paging on the LAI, and if the mobile terminal does not respond, the MSC sends paging to the MME; before the timer is overtime, if the MSC receives the mobile terminal position updating information of the MME, the timer is closed, and paging is directly sent to the MME when an incoming call exists; before the timer is overtime, if the periodic TAU timer is overtime, the mobile terminal carries out LAU and sends an LAU request to the MSC; the MSC deletes the SGs interface and the mobile terminal deactivates the ISR. When there is an incoming call, MSC directly pages the mobile terminal on the 2G/3G network; the MSC directly sends a paging request to the MME when the timer expires, and informs the MME that the paging request does not need to be sent to the SGSN. Therefore, the paging request can be prevented from being carried out in two networks, so that the air interface resources are saved, the interactive information between network devices is reduced, and the paging activating efficiency is improved.
