Abstract

Provided in embodiments of the present invention are a method and device for displaying a network name. During a joint attachment process or a joint tracking domain location update process, a mobility management entity (MME) in a first network determines whether or not the operator to which a public land mobile network identifier (PLMN ID) corresponding to the first network belongs is identical to the operator to which a PLMN ID corresponding to a second network belongs. If not identical, then the MME transmits network name information to the UE, thus allowing the UE to display the network name corresponding to the network name information, where the first network and the second network are networks that the UE jointly registered to during the joint attachment process or the joint tracking domain update process, the first network is a long term evolution (LTE) network, and the second network is either a 2G network or a 3G network. Use of the technical solution ensures that the network name displayed by a terminal is consistent with the network name that is recorded by a network device to have been displayed by the UE.

Description

Network name display method and device

The present invention relates to the field of wireless communications, and in particular, to a network name display method and apparatus. Background technique

The third-generation partner, the 3rd generation partnership project (3GPP), is based on the existing second-generation mobile communication (2nd generation, 2G) and third-generation mobile communication (3rd generation, 3G) networks. Evolved packet system (EPS). The EPS network includes an evolved universal mobile telecommunication system territorial radio access network (E-UTRAN) and an evolved packet core network (EPC). In the initial stage of EPS network construction, operators already have mature circuit switch (CS) networks, while EPS networks only deal with packet switched (PS) services. Due to the protection of CS network investment and the deployment strategy of EPS network, operators can use the original CS mobile management device to provide CS services. Based on this requirement, 3GPP has extended the mobile switching center/visitor location register (MSC/VLR) and the monthly GPRS support node in the existing 2G or 3G network. , SGSN) Gs interface function, the SGs interface between the MSC/VLR and the mobility management entity (MME) is defined in the EPC network, where GPRS is a general packet radio service (general packet radio service) )abbreviation of. Based on the SGs interface function, 3GPP proposed "CS fallback" (CSFB) technology and SGs short message over SGs (SMS) technology. The CSFB technology enables the user equipment (UE) under the E-UTRAN coverage to fall back to the CS domain of the 2G/3G network through the E-UTRAN when the CS voice service needs to be processed to complete the CS voice service processing; the SMS over SGs technology allows The UE residing under the E-UTRAN reuses the existing CS domain device to implement short message transmission in the CS domain.

In order to greatly reduce operators' heavy wireless access network deployment costs, 3GPP proposes the idea of network sharing, that is, public land mobile network of multiple operators (public land mobile network, PLMN), or multiple PLMNs of one operator, can share the same radio access network to provide wireless communication services. For CSFB technology and SMS over SGs technology, operators also put forward the need for CS domain network sharing, mainly in the following two scenarios.

Scenario 1, the traditional carrier upgrades the existing CS domain network (including 2G network and 3G network) to support CSFB technology and SMS over SGs technology, that is, operators can share multiple PLMNs operated by themselves, or by signing roaming agreements. The PLMNs of other operators are shared to provide CS services for UEs residing under E-UTRAN.

Scenario 2, the emerging pure PS service operator leases the traditional carrier's CS domain network by signing the agreement to support CSFB technology and SMS over SGs technology.

In the above CS domain network sharing scenario, for the same UE residing in the E-UTRAN, there may be multiple available PLMNs to provide CS services. In the UE-initiated joint attach process or the joint tracking area update process, if multiple available PLMNs provide CS services for the UE, the MME is currently tracking according to the PLMN reported by the evolved base station (eNB). Select the appropriate PLMN for the location information of the zone and the CS domain network selection policy of the operator. The UE is assigned a corresponding CS domain location area identification (LAI) based on the location information of the selected PLMN and the tracking area where the UE is located, and the associated MSC/VLR is selected based on the LAI. After the joint attach process is completed, the UE receives the attach accept sent by the MME, the attach accept carries a tracking area identity list (TAI list), the LAI and the VLR temporary mobile user recognizes another ll code (temporary Mobile subscriber identity, TMSI ). For the UE, the UE acquires the LAI and VLR TMSI means that the attached CS domain succeeds.

After the joint attach process is completed, the UE is successfully registered to the operator's network, and the UE should display the registered network name. Alternatively, after the joint tracking area update process, the UE should display the registered network name. Currently, the UE displays the network name based on two strategies.

Strategy 1: The network side does not configure, and the UE displays the network name according to its configuration.

Specifically, the UE displays the network name corresponding to the PLMN ID according to the PLMN identity (ID) of the currently registered network.

However, in some scenarios, the UE cannot determine which network name the corresponding PLMN ID corresponds to. Policy 2: The network name to be displayed is sent to the UE by the network side.

When receiving the network name sent by the network side, the UE may update the network name configured by the UE with the received network name, and display the updated network name.

(1) The MME notifies the UE of the network name to be displayed by the E-UTRAN mobile management information (EMM information) message, and the UE displays the notified network name. The network name notified by the MME is determined by the MME according to the home PLMN (home PLMN, HPLMN) of the MME.

(2) The MSC/VLR sends the registered network name of the CS domain network to the MME through the SGs interface.

The MME notifies the UE of the network name to be displayed through the EMM Information message, and the UE displays the notified network name. The network name notified by the MME is the name of the MME according to the policy of the MME.

The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. It is a partial embodiment of the invention, and not all of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

For the policy 2 in the above, the EMM Information message sent by the MME is an optional message, that is, the MME may not send an EMM Information message to the UE. However, if the MME does not send an EMM Information message to the UE, the MME does not know whether the UE displays the network name corresponding to the PLMN ID of the LTE network or the network name corresponding to the PLMN ID of the CS domain network.

On the other hand, for example, when the UE is on a 3G network (such as high-speed uplink packet access (High Speed)

Uplink Packet Access (HSPA) Network) Switches to the LTE network when performing VoIP services. At this time, when the user dials or accepts or triggers the VoIP service, the UE displays the network name of the 3G network, and the user determines, according to the network name displayed by the current UE, that the network currently camped or served is a 3G network. However, if the UE performs a PS handover (handover, HO) and switches to the LTE network in the process of performing the VoIP service, the UE receives the LTE network in the LTE network performing the combined tracking area update process. The EMM information message sent by the MME. At this time, the UE displays the network name notified by the EMM information message. If the network name of the 3G network It is said that the network name notified by the EMM Information message is different, which may reduce the user's feelings and cause complaints. Therefore, in order to avoid this problem, in the VoIP service process, the network name displayed by the UE due to the execution of the PS HO should be avoided.

Alternatively, when the UE performs the voice service of the CS domain on the 2G network or the 3G network, the network name displayed by the UE may be the network name of the 2G network or the 3G network. However, when the reverse voice service continuity (RSRVCC) needs to be performed in the continuous process of performing the voice service, and is switched to the LTE network or the 3G network, the UE will receive the current according to the current The GMM information or the EMM information message sent by the SGSN or the MME of the LTE network or the 3G network, and the UE displays the network name notified by the GMM Information and the EMM information message. In this case, the network name displayed by the UE when triggering the voice service of the CS domain may be inconsistent with the network name displayed when the UE switches to the LTE or 3G network.

Network or lxRTT network of code division multiple access (CDMA) networks.

In order to solve the above problem, an embodiment of the present invention provides a network name display method. As shown

As shown in 1, the method includes the following steps.

Step 110: In the process of the joint attach process or the joint tracking domain location update process, the mobility management entity MME in the first network determines that the public land mobile network identifier PLMN ID corresponding to the first network belongs to the operator and the second Whether the operator to which the PLMN ID corresponding to the network belongs is the same; Step 120, if not the same, the MME sends the network name information to the UE, so that the UE displays the network name corresponding to the network name information, where The first network and the second network are networks that are jointly registered by the UE in the joint attach procedure or the joint tracking domain update procedure, where the first network is a long term evolution LTE network, and the second The network is a 2G network or a 3G network.

In this embodiment, the mobility management device of the first network sends network name information to the UE, so that the UE can display the corresponding network name according to the received network name information, thereby avoiding moving. The network name corresponding to the PLMN ID of the network, and the problem that the UE is not sure which network name corresponding to the PLMN ID is displayed.

Another embodiment of the present invention further provides a network name display method. As shown in Figure 2, the method includes the following steps.

Step 210: In the process of the joint attach process or the joint tracking domain location update process, the mobility management entity MME in the first network determines that the public land mobile network identifier PLMN ID corresponding to the first network belongs to the operator and the second Whether the carrier to which the PLMN ID corresponding to the network belongs is the same.

The first network is one of the networks to which the UE is jointly attached, such as an LTE network. Step 220: If not, the MME sends network name information to the UE. After receiving the network name information sent by the MME, the UE displays a network name corresponding to the network name information, where The first network and the second network are networks that are jointly registered by the UE in the joint attach procedure or the joint tracking domain update procedure, where the first network is a long term evolution LTE network, and the second The network is a 2G network or a 3G network.

The network name information may be a network name, a PLMN ID, or a network name and a PLMN ID.

Specifically, if the joint attach procedure or the joint tracking domain location update procedure is performed, the UE is jointly attached to the LTE network and the 2G network or jointly attached to the LTE network and the 3G network, where the MME may be an MME of the LTE network, and the MME The network name information may be sent to the UE through an EMM information message. Different from the prior art, in this embodiment, if the MME determines that the operator to which the PLMN ID of the LTE network belongs and the operator to which the PLMN ID of the CS domain network belongs are different, the EMM information message is a message that must be sent, instead of Is an optional message.

If the operator to which the PLMN ID of the LTE network belongs is different from the carrier to which the PLMN ID of the 2G or 3G network belongs, the MME sends the network name information to the UE, where the network name information may be the home PLMN ID of the MME. It may also be the PLMN ID of the LTE network, and may also be the PLMN ID of the CS domain network.

Further, in this embodiment, if the operator to which the PLMN ID of the LTE network belongs is the same as the carrier to which the PLMN ID of the 2G or 3G network belongs, the MME may send the EMM information to the UE. The message may also not send an EMM information message to the UE. That is, if the operator to which the PLMN ID of the LTE network belongs is the same as the operator to which the PLMN of the 2G or 3G network belongs, the EMM information message is still an optional message.

In the embodiment of the present invention, if the MME determines that the operator to which the PLMN ID of the LTE network belongs and the operator to which the PLMN ID of the 2G or 3G network belongs is different, the MME sends an EMM Information message to the UE, and the message is a message that must be sent. Therefore, the UE cannot determine which network name is displayed during or after the execution of the CSFB joint attach and joint tracking area update process, and ensures that the network name displayed by the terminal and the UE recorded by the mobility management device are displayed. The network name is consistent, which avoids the problem that the network name displayed by the UE changes and sends changes during the execution process, ensures the consistency of the network name displayed by the UE, and improves the user experience.

Further, if the first network is an LTE network, during the execution of the CSFB service, the UE falls back from the first network to the second network. At this time, the network name displayed by the UE may change, which is easy. Causes a bad user experience. Similarly, the UE may encounter the same problem when performing voice services. In order to overcome this problem, the above may also include the following steps.

In step 230, the UE changes to the second network in the process of performing a service, and the MME sends the network name information to the first mobility management device of the second network, so that the second network is configured. The first mobility management device sends the network name corresponding to the network name information to the UE for display; or, in the process of performing a service, the UE changes to a third network, where the MME sends the network name information Sending to the second mobility management device of the third network, so that the second mobility management device of the third network sends the network name corresponding to the network name information to the UE for display.

Specifically, performing a circuit switched fallback CSFB service to drop the UE to the second network, where the MME sends the information of the network name to the mobility management device of the second network, and the mobility management device of the second network The information about the network name is sent to the UE, and the UE displays the network name corresponding to the information of the network name. At this time, the first network is an LTE network.

Or performing voice service to switch the UE to a second network, where the MME sends the network name information to a mobility management device of the second network, where the mobility management device of the second network uses the network name The information is sent to the UE, and the UE displays information corresponding to the network name. Network name.

Sending, by the MME, the information of the network name previously sent to the UE to the mobility management device of the second network, where the mobility management device of the second network sends the information of the network name to the UE, so that the UE displays The network name is the same as the previously displayed network name

Another embodiment of the present invention provides a network name display method.

Considering the prior art, after the UE attaches to the LTE network, the UE displays the network name of the LTE network. However, when the CSFB service triggers the UE to fall back to the 2G network or the 3G network or switch the voice service to the 2G network or the 3G network or the 4G network (such as the LTE network), the UE displays the 2G network or the 3G network or 4G where the UE is currently camped. The network name of the network. Or, if the UE falls back to the 2G network or the 3G network or switches the voice service to the 2G network or the 3G network or the 4G network (such as the LTE network), and the UE receives the GPRS mobility management information sent by the SGSN of the 2G network or the 3G network. (GPRS mobile management information, GMM information) message, or if the UE receives a mobility management information (MM Information) message sent by the MSC/VLR of the 2G network or the 3G network, the UE displays the GMM information message or the MM information. The network name of the message notification, or if the UE receives the E-UTRAN mobile management information (EMM Information) message sent by the MME of the 4G network, the UE displays the network name notified by the EMM information message.

Or

In the prior art, when the UE performs a Voice over Internet Protocol (VoIP) service on the 3G network, the UE switches to the LTE network. At this time, when the user dials or accepts or triggers the VoIP service, the UE displays the network name of the 3G network, and the user determines whether the currently camped network or the network serving the UE is the 3G network according to the network name displayed by the current UE. However, if the UE performs a PS handover (PS handover) in the execution of the VoIP service procedure and switches to the LTE network, and performs a joint tracking area update procedure on the LTE network, the UE displays the network name of the received EMM information notification, or If the UE does not receive the EMM information, the UE displays the network name of the current network.

However, if the UE is attached to the LTE network, the network name displayed and the UE fall back to the 2G network or 3G. The network name displayed on the network is inconsistent, or the network name displayed by the UE during the VoIP service execution process is inconsistent, which may result in a poor user experience and may cause user complaints.

For example, in the process of performing the CSFB service, when the user dials or accepts or triggers the CSFB service, the network name displayed by the UE may be the network name of the LTE network. However, when the UE falls back to the 2G network, the UE displays the corresponding network name according to the PLMN ID of the currently used 2G network, or when the UE falls back to the 3G network, the UE displays the corresponding according to the PLMN ID of the currently used 3G network. Network name. Or, if the UE receives the GMM information message sent by the SGSN of the 2G network or the 3G network, or the UE receives the MM information message sent by the MSC/VLR of the 2G network or the 3G network, the UE displays the network notified by the GMM information message or the MM information message. name. In this case, the network name displayed by the UE when dialing or accepting or triggering the CSFB service may be inconsistent with the network name displayed when the UE falls back to the 2G network or the 3G network.

For example, after the UE triggers the VoIP service on the LTE network, the user determines, according to the network name displayed by the current UE, the network currently camped by the UE or the network currently serving the UE. At this time, the network name displayed by the UE may be an LTE network. Network name. However, when a single radio voice call continuity (SRVCC) needs to be performed in the process of performing a VoIP voice service, the UE switches to a 2G network or a 3G network, and the UE may be based on the currently used 2G network or The PLMN ID of the 3G network displays the corresponding network name, or if the UE receives the GMM information message sent by the SGSN of the 2G network or the 3G network, or if the UE receives the MM information message sent by the MSC/VLR of the 2G network or the 3G network, The UE displays the network name of the GMM information message or the MM information message notification. In this case, the network name displayed by the UE when the VoIP service is triggered may be inconsistent with the network name displayed when the UE falls back to the 2G network or the 3G network.

For another example, when the UE performs the voice service of the CS domain in the 2G network or the 3G network, the network name displayed by the UE may be the network name of the 2G or 3G network. However, when the reverse single radio voice call continuity (rSRVCC) needs to be performed in the continuous process of performing the voice service, the UE switches to the LTE network or the 3G (such as HSPA) network. The UE may send the GMM information message sent by the SGSN of the LTE network or the 3G network according to the current request, or receive the EMM information message sent by the MME, or if the UE receives the MSC/VLR of the 3G network. The MM information message sent by the UE, the UE displays the network name notified by the GMM information, EMM information message or MM information message. In this case, the network name displayed by the UE when triggering the voice service of the CS domain may be inconsistent with the network name displayed when the UE switches to the LTE or 3G network.

For another example, when the UE performs the voice service of the 2G network or the 3G network CS domain, the network name displayed by the UE may be the network name of the 2G network or the 3G network. However, when the UE needs to perform CS handover (CS HO) in the continuous process of performing the voice service, thereby switching to another 2G network or a 3G network, the UE will be based on the 2G network or the 3G network used after the handover. The PLMN ID displays the corresponding network name, or if the UE receives the GMM information message sent by the SGSN/MME of the 2G network or the 3G network, or if the UE receives the MSC/VLR of the 2G network or the 3G network; Information message, the UE displays the network name of the GMM information message or the MM information message notification. In this case, the network name displayed by the UE when triggering the voice service of the CS domain may be inconsistent with the network name displayed when the UE switches to another 2G network or 3G network.

In response to the above problem, another embodiment of the present invention provides a network name display method. It should be noted that the method of this embodiment may be performed after step 230 of the above embodiment, for example, step 240, or may be performed separately from the above embodiment. As shown in FIG. 3, the embodiment includes the following steps.

Step 310: The first mobility management device in the first network acquires the first network name information, where the first network name information is a network name currently displayed by the user equipment UE and/or a current registration of the current UE of the UE Network, or a network in two networks that are currently jointly registered by the UE.

Step 320: If the UE changes to the second network in the process of performing the service, the first mobility management device sends the first network name information to the second mobility management device in the second network, so that the The second mobility management device sends the network name corresponding to the first network name information to the UE for display.

In this embodiment, the information about the network name displayed by the current UE is sent by the first mobility management device to the second mobility management device in the second network, where the mobility management device of the second network uses the network name. The information is sent to the UE for display, such that the network name displayed by the UE is the same as the previously displayed network name. Correspondingly, in another aspect of the present invention, a method for displaying a network name is provided, and the method is a method performed by a second mobility management device in the second network. As shown in FIG. 4, this embodiment includes the following steps.

Step 410: If the user equipment UE is in the service process of the first network, the UE changes from the first network to the second network, and the second mobility management device in the second network receives the first network. The network name information sent by the first mobility management device, wherein the network name information is a network name currently displayed by the UE and/or a public land mobile network identifier PLMN corresponding to the network name currently displayed by the UE ID.

Step 420: The second mobility management device sends the network name corresponding to the network name information to the UE for display.

In this embodiment, the information about the network name displayed by the current UE is sent by the first mobility management device to the second mobility management device in the second network, where the mobility management device of the second network uses the network name. The information is sent to the UE for display, such that the network name displayed by the UE is the same as the previously displayed network name.

Correspondingly, another embodiment of the present invention provides a network name display method. As shown in FIG. 5, this embodiment includes the following steps.

Step 510: The first mobility management device in the first network acquires network name information corresponding to the network name currently displayed by the UE.

The network name information is a network name currently displayed by the UE and/or a PLMN ID corresponding to a network name currently displayed by the UE, where the first network is a network currently registered by the UE. The UE can register two networks at the same time, for example, by a joint attach procedure to register to two networks, such as a 2G or 3G network, and an LTE network.

The first mobility management device may obtain network name information corresponding to the network name currently displayed by the UE in multiple manners.

For example, after the UE successfully registers with the network, the UE displays the network name of the registered network, the network name, as described in the above embodiment or the background art. In this case, the UE In the process of successfully registering to the first network, the first mobility management device sends the network network information to the UE. Therefore, the first mobility management device can obtain the network name corresponding to the network name information sent by itself.

Alternatively, the UE may also display the network name according to a prior configuration. In this case, in order to keep the network name information displayed by the UE recorded by the first mobility management device and the network name actually displayed by the UE, the first mobility management device has the same configuration as the UE side, so that the first The mobility management device can obtain the identifier of the PLMN corresponding to the network name displayed by the UE according to the configuration.

The UE displays the network name according to the configuration of the UE. The configuration may be implemented in multiple manners. For example, the configuration may be: the UE displays the network name corresponding to the PLMN identifier of the registered network, or The UE displays the network name and the like corresponding to one of the obtained multiple PLMN identifiers. But no matter what configuration, the same configuration will exist on the mobility management device.

It should be noted that, for different networks, the first mobility management device may be different, for example, may be an MME, an SGSN, or an MSC server.

For example, the first mobility management device is an MME. After the UE performs the combined attach process or the combined tracking area update process, the UE receives the network name to be displayed sent by the MME through the EMM information or through a combined attach accept message or The PLMN ID sent by the combined tracking area accept message, and displays the network name corresponding to the received PLMN ID or displays the received network name, where the PLMN identifier is the PS network to which the MME belongs. The PLMN identity (ie, the LTE PLMN ID), or the PLMN identity is the PLMN identity (ie, the CS PLMN ID) of the CS network that the MME registers with through the MSC server. The MME may determine, according to the PLMN identifier sent to the UE, the PLMN identifier as the PLMN identifier corresponding to the network name displayed by the UE. The MME does not send the mobility management information to the UE, and the UE displays the network name according to the configuration of the MME. The MME also determines the PLMN identifier corresponding to the network name displayed by the UE according to the same configuration on the MME. Alternatively, the MME may determine the network name displayed by the UE according to the network name that is sent to the UE.

As another example, the mobility management device is an SGSN or an MSC server. The SGSN or the MSC server carries the network name information in the GMM information or the MM Information message according to the registered PLMN identity. The UE sends the message to the UE, and the UE displays the message to the user according to the received network name. The PLMN identifier is a PLMN identifier registered by the SGSN or the MSC server. Alternatively, the SGSN or the MSC server may determine the network name displayed by the UE according to the network name that is sent to the UE. Obtain and so on by interacting with the UE. Any method capable of acquiring the network name information can be applied to the embodiment of the present invention.

Step 520: Perform the service process to change the UE to the second network, where the first mobility management device sends the network name information to the second mobility management device in the second network, where the second mobility management device The network name corresponding to the network name information is sent to the UE, and the UE displays the received network name.

Specifically, the UE is returned to the second network in the process of performing the CSFB service, where the first mobility management device sends the network name information to the second mobility management device, where the second mobility management device uses the network name information. A corresponding network name is sent to the UE, and the UE displays the received network name. In this case, the first network is an LTE network, and the second network is a CS domain network. If the UE is attached to the third network when attached to the LTE, the second network may be the same as or different from the third network.

Or, the UE is switched to the second network in the process of performing the voice service, where the first mobility management device sends the network name information to the second mobility management device, where the second mobility management device corresponds the network name information The network name is sent to the UE, and the UE displays the received network name. In this case, the first network and the second network may be one of an LTE network, a 2G network, and a 3G network, and the first network is different from the second network. If the UE is attached to the third network when attached to the first network, the second network may be the same as or different from the third network.

For example, if the first network is an LTE network, the second network is a 2G network or a 3G network. After the UE switches from the first network or falls back to the second network, the MSC server or the SGSN in the second network sends mobility management information (such as MM Information or GMM Information) to the UE, where the mobility management information is Carrying the network name, the UE displays the network name received, so that the UE still keeps the displayed network name unchanged, without displaying the switch or the backward The network name of the network.

The second mobility management device may obtain the corresponding network name according to the network name information, and then send the network name to the UE, for example,

If the network name information is the network name currently displayed by the UE, the second mobility management device directly obtains the network name according to the network name information, and sends the network name to the UE;

If the first network name information is the PLMN ID corresponding to the network name currently displayed by the UE, the second mobility management device may acquire the network name corresponding to the PLMN ID according to the PLMN ID, and send the network name to the UE. The second mobility management device prestores a correspondence between each PLMN ID and a network name. Of course, the correspondence may also be obtained by other means. Or, if the first network name information is the network name currently displayed by the UE and the PLMN ID corresponding to the network name currently displayed by the UE, the second mobility management device may also directly obtain the network name information according to the network name information. The network name is sent to the UE. .

Optionally, the first mobility management device sends the network name information to the second mobility management device in multiple manners. For example, the first mobility management device sends a request message to the second mobility management device, where the request message includes the network name information; wherein the request message includes but is not limited to a location update request message or a service request message.

In the first example, when the UE performs the CSFB service, the MME may carry the network name information in a location update request message sent to the MSC server.

In the second example, the UE acts as the called party of the CSFB voice service, and the MME may carry the network name information in a service request message (service request) sent to the MSC server; or the UE acts as the calling party of the CSFB voice service. The MME may carry the network name information in a service request message or other request message sent to the MSC server.

In a third example, before the UE starts to perform the CSFB service, the first MSC server serves the UE, where the first MSC server is the mobility management device corresponding to the first 2G or the first 3G network, and the first 2G Or the first 3G network is a CS domain network in the network jointly registered by the UE. When the UE is the called party or the calling party of the CSFB voice service, the UE falls back to the second MSC server, and the second MSC server serves the UE in the second 2G or the second 3G network. If the first MSC server and The second MSC server is different, and the second MSC server needs to obtain the first network name information from the first MSC server. In this case, the second MSC server acquires the network name information from the first MSC VLR by "send identification message".

It should be noted that the embodiment of the present invention is not limited to the CSFB voice service, and includes all CSFB services, where the CSFB service includes CSFB voice service, CSFB location service (LCS) service, and CSFB call independent supplementary service. , CISS), and one of the CSFB short message services. Other CSFB services are the same as CSFB voice services, and will not be described in this article.

In the fourth example, when the UE performs a voice over internet protocol (VoIP) service on the LTE network, if the VoIP service is switched from the LTE network to another PS domain network, such as a high speed uplink packet access technology (high speed uplink) Packet access, HSUPA) The MME carries the network name information in the handover message sent to the SGSN.

In the fifth example, when the UE performs VoIP voice service on a 3G network (such as an HSUPA network), performs packet switched (PS) handover (HO), and switches to LTE. In the handover process, the SGSN is sent to the MME. The switching message carries the network name information.

In the sixth example, when the UE performs VoIP voice service on the LTE network, performs single radio voice call continuity (SRVCC), and switches to the CS domain of 2G or 3G, and the SGSN or MME may send to the MSC server. The network name information is carried in the PS to CS handover message.

In the seventh example, when the UE performs the CS voice service on the 2G or 3G network, and performs the voice service continuous process, the reverse single radio voice call continuity (SRVCC) needs to be performed, and the UE switches to LTE or The HSPA network, the MSC server carries the network name information in a CS to PS handover message sent to the SGSN or the MME.

In the eighth example, when the UE performs the CS voice service on the 2G or 3G network, and performs the CS handover in the process of performing the voice service, switching to another 2G or 3G network, the MSC server is sent to the MSC server. The network name information is carried in the CS to CS handover message.

It should be noted that, in the foregoing example, the network name information may be carried in the foregoing message. A newly added information unit, the newly added information unit is dedicated to storing the network name information. It should be noted that the foregoing first mobility management device and the second mobility management device may include, but are not limited to, an MSC/VLR, ie, an MSC server, a Serving GPRS Support Node (SGSN), or an MME, where the MSC server may It is the MSC server of SRVCC, it can also be the MSC server of rSRVCC, or it can be the MSC server of CSFB.

In addition, if the second network is a pure PS domain network, such as an LTE network, the method in this embodiment ends, and the first mobility management device is a mobility management device in the pure PS domain network; The second network is a network in which the CS domain and the PS domain coexist, such as a 2G or 3G network, and the first mobility management device may be a mobility management device in the PS domain network, or may be a mobility management device in the CS domain network. The method of the example further includes step 530.

In this embodiment, the network name information is sent to the network device in the network after the UE is changed, so that the network device can send the network name information to the UE, thereby maintaining the network name displayed by the UE and the network name displayed before the change. Consistent, enhances the user experience.

Step 530: The first mobility management device sends a message indicating that the third mobility management device in the second network does not send the network name information to the UE.

The first mobility management device may indicate the PLMN ID of the second network by sending a request message, where the request message includes indication information for indicating that the second mobility management device is not the second in the second network. The mobility management device does not send a mobility management information message.

The request message includes but is not limited to a location update request message, a service request message, a handover request message (forward relocation request message), a context response message (context response), a context request message (context request), and a location update request message (location update Request ) or service request message.

In the first example, when the UE performs the CSFB service, the MME may carry the indication information in a location update request message sent to the MSC server.

In the second example, the UE acts as the called party of the CSFB voice service, and the MME may send it to the MSC. The service service request of the server carries the indication information. Alternatively, the UE is the calling party of the CSFB voice service, and the MME may carry the indication information in a service request or other request message sent to the MSC server.

In the third example, when the UE is the calling party of the CSFB voice service and performs the location update process, the MME may carry the indication information in the context request sent to the SGSN.

In a fourth example, before the UE starts to perform the CSFB service, the first MSC server serves the UE, where the first MSC server is the mobility management device corresponding to the first 2G or the first 3G network, and the first 2G Or the first 3G network is a CS domain network in the network jointly registered by the UE. When the UE is the called party or the calling party of the CSFB voice service, if the first MSC server and the second MSC server are different, the first MSC server sends the indication information to the second MSC server by using a "send identification" message.

In the fifth example, when the UE performs the VoIP voice service on the LTE network, the SRVCC is performed, and the CS domain is switched to the 2G or 3G CS domain, and the SGSN or the MME carries the indication information in the PS to CS handover message sent to the MSC server.

In the sixth example, when the service is a voice service, the MME or the SGSN carries the indication information in a handover message sent to the MSC server.

In the seventh example, when the service is the voice service, the MME carries the indication information in a PS to CS handover message sent to the MME.

It should be noted that, in the above example, the indication information may be carried in a new information unit in the message, and the added information unit is specifically configured to store the indication information.

In addition, if the second mobility management device is a mobility management device in a PS domain network, the third mobility management device is a mobility management device in a CS domain network, if the second mobility management device is in a CS domain network Mobile management device, the third mobility management device is a mobility management device in a PS domain network.

The mobile management device should send the network name information to another corresponding mobile in the CS domain or PS domain. The management device sends the indication information, so that the UE can obtain only the name information sent by one mobility management device, so that the network name displayed by the UE is consistent with the network name displayed before the change, and the user's body is fully enhanced.
