[0136] Before describing the embodiments of this application, the relevant technologies are briefly introduced below:

[0137] I. User plane solution for Evolved Packet System (EPS) network supporting IMS

[0138] As shown in Figure 2, steps 1 to 3 constitute the establishment process of a Packet Data Network (PDN) connection (or session) carrying IMS signaling and data. For 5G systems, the process is similar, establishing a Protocol Data Unit (PDU) session. During this process, the Mobility Management Entity (MME) learns the UE's Radio Access Technology (RAT) type and Access Point Name (APN), thus knowing that the UE's access technology and session are used for IMS. The UE also obtains information about the Proxy-Call Session Control Function (P-CSCF). The related connection / session will be referred to as an IMS session. In this scheme, the IMS session uses the EPS user plane. Steps 4 to 5 involve the UE initiating an IMS registration process with the P-CSCF through the IMS session, achieving registration in the IMS system. After completing IMS registration, the UE can use various subscribed IMS services. Steps 6 to 10 are the process of the UE initiating IMS calling communication. Step 6 is the UE initiating a call to the peer UE. Step 7 is the peer UE responding to the call. Steps 8 to 9 are the acknowledgment responses between the UE and the peer UE being received. Step 10 is the peer UE responding, completing the IMS communication establishment. The UE and the peer UE can then transmit IMS media data (such as voice).

[0139] The called party process is similar, except that the UE receives the IMS Invitation (INVITE) message, responds to the IMS INVITE and the IMS Provisional Response with Acknowledgment (PRACK), and finally replies.

[0140] II. Control plane scheme for EPS network supporting IMS

[0141] As shown in Figure 3, the difference between this scheme and the user plane scheme in Figure 2 is that the IMS session uses the control plane of EPS, and the subsequent IMS process is forwarded through MME and Serving Gateway (SGW) / Packet Data Network Gateway (PGW). It uses the control plane of MME and eNB and the control plane of MME and SGW, instead of using the user plane between eNB and SGW.

[0142] In the aforementioned EPS network IMS-supported scheme, the UE can transmit other related information or data while conducting IMS communication. However, in certain access scenarios, such as when the UE and eNB are connected via a high-bandwidth narrowband connection, each UE has extremely limited bandwidth. If this bandwidth is used to transmit voice data, there is almost no available bandwidth to transmit other related information or data, which would lead to interruption of voice data transmission. For example, if the UE's signal strength in the eNB network is low, transmitting other related information and data while transmitting voice data would interfere with voice data transmission. Furthermore, Non-Access Stratum (NAS) signaling always has a higher priority than user plane data (including IMS-related data, as it is carried over the IMS session). NAS signaling does not have different priorities based on its purpose (i.e., first-come, first-served). During IMS communication, NAS signaling may still be transmitted between the MME and the UE, causing contention for IMS media data transmission resources, resulting in increased jitter or even short-term interruptions in media transmission. As a result, users perceive severe voice jitter or even a brief inability to hear voice. Therefore, ensuring the effectiveness of IMS communication is a problem that needs to be solved in certain access scenarios.

[0143] In view of this, embodiments of this application provide an information processing method, an information processing apparatus, and a communication device to solve the problem of poor IMS communication performance in some access scenarios in related technologies.

[0144] The information processing method provided in this application will be described in detail below with reference to the accompanying drawings, through some embodiments and application scenarios.

[0145] Figure 4 shows a flowchart of an information processing method provided in an embodiment of this application. As shown in Figure 4, the information processing method includes the following steps:

[0146] Step 401: Based on access-related information, the terminal performs a first operation, which includes at least one of the following:

[0147] Send first information to a first network node or a second network node, the first information being used to instruct the terminal to support local invalidation or deactivation of a first bearer, the first bearer being a bearer different from the bearer associated with the terminal's IMS session;

[0148] When the terminal is in IMS communication mode, the transmission of the second information is prohibited or stopped;

[0149] When the terminal is in IMS communication mode, sending third-party information is permitted;

[0150] The access-related information includes at least one of the following: the type of RAT, the signal strength of the access network, and the available bandwidth provided by the access network to the terminal.

[0151] In this application embodiment, "network node" can be expressed as or replaced by "network function" or "network device".

[0152] The first network node can be, for example, a base station, and the second network node can be, for example, an MME, an AMF, or an SMF.

[0153] Deactivating the first bearer, also known as deactivating the first bearer, can be understood as putting the first bearer into an inactive state.

[0154] An IMS session can include a PDU session or a PDN connection used to transmit IMS signaling and IMS media data.

[0155] The terminal supports local invalidation or deactivation of the first bearer, which can be understood as the terminal being able to locally invalidate or deactivate a bearer that is different from the bearer associated with the IMS session when conducting IMS communication, thereby ensuring that IMS communication is not interfered with or interrupted by other non-IMS communication bearers.

[0156] When the terminal is in IMS communication mode, prohibiting or stopping the transmission of second information can be understood as prohibiting or stopping the transmission of information that would interfere with or interrupt IMS communication. Second information can be understood as information that interferes with IMS communication.

[0157] The third information can be understood as information related to IMS communication. Therefore, when the terminal is in IMS communication state, the terminal is allowed to send the third information.

[0158] In this embodiment, the terminal performs the first operation by taking into account access-related information, which can effectively prevent IMS voice communication from being interfered with or even interrupted by other services, thereby ensuring the IMS communication effect under various access scenarios.

[0159] It should be noted that the UE can establish IMS communication (or IMS voice call) through LTE. The specific steps for establishing IMS communication can be found in Figures 2 and 3. Specifically, it can be done using either the User Plane (UP) method or the Control Plane (CP) method.

[0160] In some embodiments, the terminal being in IMS communication state includes at least one of the following:

[0161] The terminal is performing IMS communication;

[0162] The terminal's IMS call has been answered, or the terminal has answered the IMS call;

[0163] A second bearer is established, which is a bearer for transmitting IMS media data of the terminal.

[0164] In some embodiments, the terminal performs a first operation based on access-related information, including at least one of the following:

[0165] When the RAT type is Geostationary Orbit (GEO) RAT type, the terminal performs the first operation;

[0166] When the RAT type is Medium Earth Orbit (MEO) RAT type, the terminal performs the first operation;

[0167] When the RAT type is a geostationary narrowband Internet of Things (NB-IoT (GEO)) RAT type, the terminal performs the first operation;

[0168] When the RAT type is Medium Earth Orbit Narrowband Internet of Things (NB-IoT(MEO)) RAT type, the terminal performs the first operation;

[0169] If the signal strength of the access network is lower than or equal to a first threshold, the terminal performs a first operation;

[0170] If the available bandwidth provided to the terminal by the access network is less than or equal to a second threshold, the terminal performs a first operation.

[0171] In some embodiments, when the RAT type is GEO RAT, the available bandwidth of the terminal is small. In this case, the terminal can perform a first operation to ensure the IMS communication effect in the access scenario.

[0172] When the RAT type is MEO RAT, the signal strength of the access network is low or unstable. In this case, the terminal can perform the first operation to ensure the IMS communication effect in this access scenario.

[0173] When the RAT type is NB-IoT (GEO) RAT, the available bandwidth of the terminal is relatively small. In this case, the terminal can perform the first operation to ensure the IMS communication effect in this access scenario.

[0174] When the RAT type is NB-IoT (MEO) RAT, the available bandwidth of the terminal is relatively small. In this case, the terminal can perform the first operation to ensure the IMS communication effect in this access scenario.

[0175] If the signal strength of the access network is lower than or equal to a first threshold, the signal strength of the access network is low. In this case, the terminal can perform a first operation to ensure the IMS communication effect in this access scenario.

[0176] If the available bandwidth provided to the terminal by the access network is less than or equal to the second threshold, the available bandwidth of the terminal is relatively small. In this case, the terminal can perform the first operation to ensure the IMS communication effect in this access scenario.

[0177] In some embodiments, the second information includes at least one of the following:

[0178] IMS signaling other than hang-up signaling;

[0179] Non-access tier NAS messages, or NAS messages other than those that transmit Short Message Service (SMS);

[0180] At least one of the pre-agreed IMS signaling and NAS messages;

[0181] At least one of the pre-configured IMS signaling and NAS messages;

[0182] Data unrelated to IMS.

[0183] In some embodiments, the hang-up signaling can be Session Initialization Protocol (SIP) BYE signaling.

[0184] For example, when a terminal is in response to a Mobile Originated (MO) operation, it can stop sending IMS signaling except for BYE and stop sending NAS messages.

[0185] For example, for MO operations, the terminal can stop sending NAS messages other than MO-SMS (including stopping the establishment of new sessions, updating sessions, etc.). It should be noted that MO-SMS will cause voice interruption, and the terminal can perform a HOLD-like operation. For example, after the UE clicks the send button, it can generate a voice notification to the remote end and the terminal user, and display a confirm send button. The terminal user decides whether and when to confirm sending the SMS (e.g., receiving a voice confirmation from the remote user).

[0186] For example, for MO operations, the terminal can be configured to prohibit sending relevant signaling to the EPS network according to an agreement or policy, or to prohibit sending relevant IMS messages to the IMS network according to an agreement or policy.

[0187] In some embodiments, the third information includes at least one of the following:

[0188] Hang-up signaling in IMS signaling;

[0189] Transmit NAS messages via SMS;

[0190] At least one of the pre-agreed IMS signaling and NAS messages;

[0191] At least one of the pre-configured IMS signaling and NAS messages;

[0192] Data related to IMS.

[0193] For example, a terminal may allow itself to send BYE signaling in IMS signaling for MO operations.

[0194] For example, a terminal can allow itself to send MO-SMS for MO operations.

[0195] For example, a terminal may allow itself to send pre-agreed or pre-configured relevant signaling for MO operations.

[0196] The above are implementation examples of the method on the terminal side. The following describes implementation examples of the method on the second network node side.

[0197] Figure 5 shows a flowchart of an information processing method provided in an embodiment of this application. As shown in Figure 5, the information processing method includes the following steps:

[0198] Step 501: The second network node performs a second operation based on the first target information, the second operation including at least one of the following:

[0199] Send a fourth message to the first network node, the fourth message being used to instruct the terminal to support local invalidation or deactivation of the first bearer, the first bearer being a bearer different from the bearer associated with the terminal's IMS session;

[0200] When the terminal is in IMS communication state, a fifth message is sent to the first network node, the fifth message being used to indicate the release or deactivation of the first bearer;

[0201] When the terminal is in IMS communication state, a sixth message is sent to the third network node. The sixth message is used to indicate to stop forwarding the first data to the terminal. The first data is data that is not related to the associated session of the IMS communication of the terminal.

[0202] When the terminal is in IMS communication state, target parameters are set, including the allocation and reservation priority (ARP) parameter of the second bearer, the second bearer being a bearer used to transmit the IMS media data of the terminal;

[0203] When the terminal is in IMS communication mode, the transmission of the seventh information to the terminal is prohibited or stopped;

[0204] When the terminal is in IMS communication state, it is allowed to send the eighth message to the terminal;

[0205] The first target information includes at least one of the following:

[0206] First information from the terminal, the first information being used to instruct the terminal to support local invalidation or deactivation of the first bearer;

[0207] The access-related information of the terminal includes at least one of the following: RAT type, signal strength of the access network, and available bandwidth provided to the terminal by the access network.

[0208] In this embodiment of the application, the second network node may be, for example, an MME, the first network node may be, for example, a base station, and the third network node may be, for example, a PGW or a UPF.

[0209] The fourth message is sent to the first network node so that the first network node knows that when the terminal is conducting IMS communication, the terminal can locally invalidate or deactivate a bearer that is different from the bearer associated with the IMS session, so that the first network node and the terminal understand each other.

[0210] When the terminal is in IMS communication state, sending the fifth message to the first network node can be understood as the first network node releasing or deactivating a bearer that is different from the bearer associated with the IMS session when the terminal is conducting IMS communication, thereby ensuring that IMS communication is not interfered with or interrupted by other non-IMS communication bearers.

[0211] When the terminal is in IMS communication mode, sending the sixth message to the third network node can be understood as the third network node not forwarding data unrelated to the terminal's IMS communication session to the terminal while the terminal is conducting IMS communication, thereby ensuring that IMS communication is not interfered with or interrupted by other non-IMS communication bearers.

[0212] When the terminal is in IMS communication mode, setting the target parameters can be understood as the second network node being able to ensure that IMS communication is not interfered with or interrupted by other non-IMS communication bearers by setting the ARP of the bearer used to transmit the terminal's IMS communication media data when the terminal is conducting IMS communication.

[0213] When the terminal is in IMS communication mode, prohibiting or stopping the transmission of the seventh message to the terminal can be understood as the second network node prohibiting or stopping the transmission of information that would interfere with or interrupt IMS communication while the terminal is conducting IMS communication. The seventh message can be understood as information that interferes with the terminal's IMS communication.

[0214] The eighth message can be understood as information related to the terminal's IMS communication. Therefore, when the terminal is in IMS communication state, the second network node is allowed to send the eighth message.

[0215] In this embodiment of the application, the second network node performs the second operation based on the first target information, which can effectively prevent the terminal's IMS voice communication from being interfered with or even interrupted by other services, thereby ensuring the IMS communication effect of the terminal under various access scenarios.

[0216] In some embodiments, the UE can establish IMS communication (or IMS voice call) via LTE. The specific steps for establishing IMS communication can be found in Figures 2 and 3. Specifically, it can be done using either the User Plane (UP) method or the Control Plane (CP) method.

[0217] In some embodiments, the terminal being in IMS communication state includes at least one of the following:

[0218] The terminal's IMS session is activated;

[0219] The second bearer is established;

[0220] The second network node receives data related to the IMS session, bearer, or channel of the terminal;

[0221] The second network node receives IMS-related data sent by the terminal.

[0222] In some embodiments, the data received by the second network node related to the terminal's IMS session, bearer, or channel can be understood as data related to downlink IMS communication in the control plane scheme.

[0223] In some embodiments, the IMS-related data received by the second network node from the terminal can be understood as uplink IMS communication-related data in the control plane scheme, and the information transmitted is known from the NAS signaling to be related to IMS communication.

[0224] For example, the second network node can learn that the IMS session is activated through a NAS Service Request or NAS Attach message sent by the UE (the message indicates that the IMS session is activated).

[0225] For example, the second network node can learn that a voice bearer with QCI=1 has been established through the bearer establishment process initiated by the PGW / SGW, thereby knowing that an IMS voice bearer (used for transmitting voice data) has been established.

[0226] For example, in a scheme that establishes IMS communication using the CP method, if the second network node receives data related to the associated session of the terminal's IMS communication, it indicates that the terminal is in the IMS communication state.

[0227] In some embodiments, the IMS session, bearer, or channel includes any one of the following:

[0228] Sessions that transmit IMS signaling and IMS media data;

[0229] Bearer or channel for transmitting IMS signaling;

[0230] Bearer or channel for transmitting IMS media data;

[0231] Bearer or channel for transmitting IMS signaling and IMS media data.

[0232] A session that transmits IMS signaling and IMS media data may contain one or more bearers or channels.

[0233] In some embodiments, the first target information includes access-related information of the terminal;

[0234] The second network node performs a second operation based on the first target information, including at least one of the following:

[0235] When the RAT type is geostationary orbit GEO RAT type, the second network node performs the second operation;

[0236] When the RAT type is a Medium Earth Orbit (MEO) RAT, the second network node performs the second operation;

[0237] In the case where the RAT type is Geostationary Orbit Narrowband Internet of Things (NB-IoT) (GEO) RAT type, the second network node performs the second operation;

[0238] In the case where the RAT type is Medium Earth Orbit Narrowband Internet of Things (NB-IoT) (MEO) RAT type, the second network node performs the second operation;

[0239] If the signal strength of the access network is lower than or equal to the first threshold, the second network node performs the second operation;

[0240] If the available bandwidth provided to the terminal by the access network is less than or equal to the second threshold, the second network node performs the second operation.

[0241] In some embodiments, setting the target parameter includes at least one of the following:

[0242] Raise the priority of the second bearer to the target priority;

[0243] Set the second bearer to be non-preemptible;

[0244] Configure the second bearer to preempt other bearers.

[0245] For example, the second network node can prevent the second bearer from being preempted by setting the voice to the highest priority (but cannot prevent the transmission of IMS signaling), or it can directly set the second bearer to be non-preemptible, or set the second bearer to be preemptible of other bearers.

[0246] In some embodiments, the seventh information includes at least one of the following:

[0247] Non-access stratum NAS messages;

[0248] NAS messages that are not related to the IMS session, bearer, or channel;

[0249] At least one of the pre-agreed NAS messages;

[0250] At least one of the pre-configured NAS messages.

[0251] For example, the second network node may stop sending NAS messages to the UE (including: stopping session updates, small data NAS), or stop sending NAS messages unrelated to the UE's IMS communication sessions. In the scheme of establishing IMS communication using the UP method, IMS-related signaling and data do not pass through the second network node.

[0252] In some embodiments, the eighth information includes at least one of the following:

[0253] NAS messages related to IMS sessions, bearers, or channels;

[0254] At least one of the pre-agreed NAS messages;

[0255] At least one of the pre-configured NAS messages.

[0256] For related descriptions of the embodiments of this application, please refer to the related descriptions of the method embodiments in Figure 4, which can achieve the same technical effects. To avoid repetition, they will not be described in detail here.

[0257] The above are method embodiments for the second network node side. The following describes method embodiments for the fourth network node side.

[0258] Figure 6 shows a flowchart of an information processing method provided in an embodiment of this application. As shown in Figure 6, the information processing method includes the following steps:

[0259] Step 601: The fourth network node performs a third operation based on the terminal's access-related information, the third operation including at least one of the following:

[0260] When the terminal is in IMS communication mode, the sending of the ninth message to the terminal is prohibited or stopped;

[0261] When the terminal is in IMS communication state, it is allowed to send the tenth message to the terminal;

[0262] When the terminal is in IMS communication state and receives the first message, a busy line (BUSY) message is sent to the sender of the first message. The first message is a message used to invite the terminal to make an IMS call.

[0263] When the terminal is in IMS communication state and receives the second message, a rejection message or failure response message is sent to the sender of the second message. The second message is IMS signaling sent to the terminal.

[0264] The access-related information includes at least one of the following: the type of wireless access technology (RAT), the signal strength of the access network, and the available bandwidth provided by the access network to the terminal.

[0265] In this embodiment of the application, the fourth network node may be, for example, a P-CSCF.

[0266] When the terminal is in IMS communication mode, prohibiting or stopping the transmission of the ninth message to the terminal can be understood as the fourth network node prohibiting or stopping the transmission of information that would interfere with or interrupt IMS communication when the terminal is conducting IMS communication. The ninth message can be understood as information that interferes with the terminal's IMS communication.

[0267] The tenth message can be understood as information related to the terminal's IMS communication. Therefore, when the terminal is in IMS communication state, the fourth network node is allowed to send the tenth message.

[0268] When the fourth network node receives an INVITE message sent to the UE, it can act as a proxy for the UE to return to Busy, thereby ensuring that the UE's current IMS communication is not interfered with or interrupted by the bearers of other IMS communications.

[0269] When the fourth network node receives other IMS messages, it can return a reject message or a failure response message, thereby ensuring that the UE's current IMS communication is not interfered with or interrupted by the bearer of other IMS communication.

[0270] In other words, the fourth network node can be configured to prohibit the sending of relevant IMS messages to the UE according to an agreement or policy, or the fourth network node can perform relevant processing on the received IMS messages sent to the UE.

[0271] In some embodiments, the fourth network node performs a third operation based on the terminal's access-related information, including at least one of the following:

[0272] In the case that the RAT type is geostationary orbit GEO RAT type, the fourth network node performs the third operation;

[0273] In the case that the RAT type is a Medium Earth Orbit (MEO) RAT, the fourth network node performs the third operation;

[0274] In the case where the RAT type is Geostationary Orbit Narrowband Internet of Things (NB-IoT) (GEO) RAT type, the fourth network node performs the third operation;

[0275] In the case that the RAT type is Medium Earth Orbit Narrowband Internet of Things (NB-IoT) (MEO) RAT type, the fourth network node performs the third operation;

[0276] If the signal strength of the access network is lower than or equal to the first threshold, the fourth network node performs the third operation;

[0277] If the available bandwidth provided to the terminal by the access network is less than or equal to the second threshold, the fourth network node performs a third operation.

[0278] In some embodiments, the ninth information includes at least one of the following:

[0279] IMS signaling other than hang-up signaling;

[0280] Pre-agreed IMS signaling;

[0281] Pre-configured IMS signaling.

[0282] In some embodiments, the tenth information includes at least one of the following:

[0283] Hang up the signal;

[0284] Pre-agreed IMS signaling;

[0285] Pre-configured IMS signaling.

[0286] For related descriptions of the embodiments of this application, please refer to the descriptions of the method embodiments in Figures 4 or 5, which can achieve the same technical effects. To avoid repetition, they will not be described again.

[0287] The above are method embodiments for the fourth network node side. The following describes the method embodiments for the first network node side.

[0288] Figure 7 shows a flowchart of an information processing method provided in an embodiment of this application. As shown in Figure 7, the information processing method includes the following steps:

[0289] Step 701: The first network node performs a fourth operation based on the second target information, the fourth operation including at least one of the following:

[0290] If the second bearer is established, the first bearer is released or deactivated;

[0291] If the second bearer is established, stop or refuse to send eleventh information to the second network node. The eleventh information is used to notify the second network node that the first network node releases or deactivates the second bearer.

[0292] If the second bearer is established and the second data is received, stop or refuse to send the second data to the terminal, where the second data is data from the first bearer;

[0293] Wherein, the first bearer is a bearer different from the bearer associated with the Internet Protocol Multimedia Subsystem (IMS) session of the terminal, and the second bearer is a bearer used to transmit the terminal's IMS media data.

[0294] The second target information includes at least one of the following:

[0295] The access-related information of the terminal includes at least one of the following: the type of wireless access technology (RAT), the signal strength of the access network, and the available bandwidth provided by the access network to the terminal.

[0296] First information from the terminal, the first information being used to instruct the terminal to support local invalidation or deactivation of the first bearer;

[0297] The twelfth message from the second network node indicates at least one of the following: the terminal supports local invalidation or deactivation of the first bearer; or the first bearer is released or deactivated.

[0298] The first network node can be, for example, a base station.

[0299] When the second bearer is established, releasing or deactivating the first bearer can be understood as the first network node releasing or deactivating a bearer that is different from the bearer associated with the IMS session when the terminal is conducting IMS communication, thereby ensuring that the terminal's IMS communication is not interfered with or interrupted by other non-IMS communication bearers.

[0300] When the second bearer is established, stopping or refusing to send the eleventh message to the second network node can be understood as the first network node stopping or refusing to instruct the second network node to release or deactivate the second bearer when the terminal is conducting IMS communication, thereby ensuring that the terminal's IMS communication is not interrupted.

[0301] When the second bearer is established and data from the first bearer is received, stopping or refusing to send data from the first bearer to the terminal can be understood as the first network node stopping or refusing to send non-IMS communication data to the terminal while the terminal is performing IMS communication, thereby ensuring that the terminal's IMS communication is not interrupted.

[0302] In some embodiments, the second target information includes access-related information of the terminal;

[0303] The first network node performs a fourth operation based on the second target information, including at least one of the following:

[0304] If the RAT type is geostationary orbit GEO RAT type, the first network node performs the fourth operation;

[0305] In the case that the RAT type is a Medium Earth Orbit (MEO) RAT, the first network node performs the fourth operation;

[0306] In the case where the RAT type is Geostationary Orbit Narrowband Internet of Things (NB-IoT) (GEO) RAT type, the first network node performs the fourth operation;

[0307] In the case where the RAT type is Medium Earth Orbit Narrowband Internet of Things (NB-IoT) (MEO) RAT type, the first network node performs the fourth operation;

[0308] If the signal strength of the access network is lower than or equal to the first threshold, the first network node performs the fourth operation;

[0309] If the available bandwidth provided to the terminal by the access network is less than or equal to the second threshold, the first network node performs the fourth operation.

[0310] For related descriptions of the embodiments of this application, please refer to the descriptions of the method embodiments in Figures 4, 5, and 6, which can achieve the same technical effects. To avoid repetition, they will not be described again.

[0311] The following provides several specific embodiments to illustrate the solutions of the embodiments of this application.

[0312] In the following embodiments, the second network node is an MME and the fourth network node is a P-CSCF.

[0313] In one embodiment, as shown in FIG8, the following steps are included:

[0314] Step 0: The UE establishes an IMS voice call via LTE (using UP mode);

[0315] Step 1:

[0316] a) UE behavior for MO operations (based on GEO RAT type):

[0317] The UE stops sending IMS signaling except for BYE, and stops sending NAS messages; or,

[0318] The UE stops sending NAS messages other than MO-SMS (including: stopping the establishment of new sessions, updating sessions, etc.); or,

[0319] According to the agreement or policy configuration, sending relevant signaling to the EPS network and sending relevant IMS messages to the IMS network are prohibited.

[0320] b) MME behavior (based on GEO RAT type and IMS session activation / IMS voice bearer establishment):

[0321] The MME stops sending NAS messages to the UE (including: stop update session, small data NAS), and IMS-related signaling and data do not pass through the MME;

[0322] MME prevents voice bearer preemption by setting the voice to the highest priority.

[0323] c) P-CSCF behavior for mobile user called party (MT) operations (based on GEO RAT type):

[0324] P-CSCF stops sending IMS messages other than BYE to the UE; or...

[0325] The P-CSCF receives the INVITE message intended for the UE and, acting on behalf of the UE, returns Busy; or...

[0326] When the P-CSCF receives another IMS message, it rejects the message or returns a failure response message; or,

[0327] According to the agreement or policy configuration, sending related IMS messages to the UE and processing received IMS messages sent to the UE are prohibited.

[0328] In this embodiment, the MME can learn that an IMS session has been activated through a NAS Service Request or NAS Attach message sent by the UE (the message indicates that the IMS session is activated). Alternatively, the MME can learn that a voice bearer with QCI=1 has been established through a bearer establishment process initiated by the PGW / SGW, thereby knowing that an IMS voice bearer (used for transmitting voice data) has been established.

[0329] In this embodiment, during the IMS voice communication process of the UE, the network and the UE can prevent the transmission of IMS voice data from being interfered with by restricting or even prohibiting the sending of NAS and IMS messages.

[0330] In another embodiment, as shown in FIG9, the following steps are included:

[0331] Step 0: The UE establishes an IMS voice call via LTE (using CP method);

[0332] Step 1:

[0333] a) UE behavior for MO operations (based on GEO RAT type):

[0334] The UE stops sending IMS signaling except for BYE, and stops sending NAS messages; or,

[0335] The UE stops sending NAS messages other than MO-SMS (including: stopping the establishment of new sessions, updating sessions, etc.); or,

[0336] According to the agreement or policy configuration, sending relevant signaling to the EPS network and sending relevant IMS messages to the IMS network are prohibited.

[0337] b) MME behavior (based on GEO RAT type and IMS session activation / IMS voice bearer establishment / IMS data reception):

[0338] The MME stops sending non-IMS-related NAS messages to the UE (thus allowing BYE to pass, but not preventing other IMS signaling from passing); here, the MME needs to identify the services carried by the NAS. The MME can identify IMS services through the channel information between the SGW and the MME included in the DL Data notification.

[0339] c) P-CSCF behavior for MT operations (based on GEO RAT type):

[0340] P-CSCF stops sending IMS messages other than BYE to the UE; or...

[0341] The P-CSCF receives the INVITE message intended for the UE and, acting on behalf of the UE, returns Busy; or...

[0342] When the P-CSCF receives another IMS message, it rejects the message or returns a failure response message; or,

[0343] According to the agreement or policy configuration, sending related IMS messages to the UE and processing received IMS messages sent to the UE are prohibited.

[0344] In this embodiment, the MME can learn that an IMS session has been activated through a NAS Service Request or NAS Attach message sent by the UE (the message indicates that the IMS session is activated). Alternatively, the MME can learn that a voice bearer with QCI=1 has been established through a bearer establishment process initiated by the PGW / SGW, thereby knowing that an IMS voice bearer (used for transmitting voice data) has been established.

[0345] In this embodiment, during the IMS voice communication process of the UE, the network and the UE can prevent the transmission of IMS voice data from being interfered with by restricting or even prohibiting the sending of NAS and IMS messages.

[0346] The information processing method provided in this application can be executed by an information processing device. This application uses an information processing device executing the information processing method as an example to illustrate the information processing device provided in this application.
