[0076] The present application will be further described in detail below with reference to the accompanying drawings and embodiments.

[0077] Off-network roaming is to use the network of another communication operator through a SIM card signed with a communication operator. Currently, there are two ways of off-network roaming: The first way is the co-construction and sharing of radio access networks, as shown in Figure 1 shown; The second way is the off-network interworking of radio access networks + core networks, as shown in Figure 2 shown.

[0078] Based on the second way, off-network roaming users (referring to users signed with a specific communication operator accessing different operator networks, abbreviated as "off-network") and on-network users (referring to users signed with a specific communication operator accessing the network of a specific communication operator, abbreviated as "on-network") in the wireless network use the same service scheduling standard for services. And currently, the measurement data reported by users is mainly on-network data. The terminal measurement data automatically collected by the minimization of drive-tests (MDT) technology can be used to detect and optimize the on-network wireless network, perform coverage optimization, capacity optimization, and Quality of Service (QoS) parameter optimization. Users can report longitude and latitude information to accurately locate and obtain data service-related information of users at different positions in the cell, and evaluate the user experience. Currently, on-network and off-network users are not distinguished.

[0079] Considering the accelerated commercialization of off-network roaming in the future, there will be on-network and off-network users in the wireless network. Currently, the service scheduling management for off-network roaming users accessing the on-network cannot be accurately located, which occupies on-network user resources and affects the user experience.

[0080] The present application provides a service scheduling method for off-network roaming users, focusing on the service management of off-network roaming users. Through the MDT technology, various network coverage situations are diagnosed, the service distribution situation and service quality are detected, network problems are located and solved, and service scheduling management for off-network roaming users is carried out to prevent off-network roaming users from occupying on-network user resources and affecting the on-network user experience.

[0081] An embodiment of the present application provides a service scheduling method, which is applied to a first network device, as shown in Figure 3 shown. The method includes:

[0082] Step 101: Receive the first information sent by the terminal, where the first information is used to determine the minimized drive test information.

[0083] In practical applications, the service scheduling method provided in this application can be applied to a communication network, which can be a fifth-generation (5G) mobile communication network, a fourth-generation (4G) mobile communication network, or other actual mobile communication networks. This application does not make specific limitations on this.

[0084] In practical applications, the first network device can be a base station, which is used to implement radio physical layer functions, resource scheduling, radio resource management, radio access control, and mobility management functions. The second network device can be a network device included in the core network of Operator A, such as a server or other devices. The third network device can be a network device included in the core network of Operator B, such as a server or other devices. The core network is used to provide data services for the terminal.

[0085] In practical applications, the terminal can be a user equipment (UE), such as a mobile phone, a computer, and can also be a cellular phone, a cordless phone, a session initiation protocol (SIP) phone, a smart phone, a personal digital assistant (PDA), a laptop computer, a handheld communication device, a handheld computing device, a satellite wireless device, a wireless modem card, a customer premise equipment (CPE), and / or other devices used for communication on a wireless system.

[0086] In an embodiment, minimized drive test mainly refers to coordinating the terminal to measure and report corresponding information through the radio access network, so that the operator can detect problems existing in the radio access network and optimize the radio access network according to the information reported by the terminal.

[0087] Step 102: Receive the second information sent by the second network device, where the second information indicates a list of services of the type with priority scheduling for off-net roaming users, and when the user corresponding to the terminal is an off-net roaming user, the list includes the user corresponding to the terminal.

[0088] In practical applications, taking the access of on-net and off-net users to the core network of Operator A as an example, this application establishes a mechanism for the list of services of the type with priority scheduling for off-net roaming users, and the list of services of the type with priority scheduling for off-net roaming users is used as one of the reference factors for service scheduling.

[0089] In one embodiment, the list of services of the off-net roaming user priority scheduling type includes off-net roaming users and services of the priority scheduling type. The list of services of the off-net roaming user priority scheduling type may further include the priority of the services. Exemplarily, the initial setting of the priority is: voice and SMS of on-net users > voice and SMS of off-net users > other data services of on-net users > other data services of off-net users. Among them, the priority of the services can be formulated based on the actual service situation, and the present application does not make specific limitations thereon.

[0090] Step 103: Obtain third information, where the third information indicates the wireless load information of the first network device.

[0091] In actual application, the wireless load information of the first network device can reflect the network situation of the first network device. The network situation includes, but is not limited to, low load situation, medium load situation, and high load situation; among them, the high load situation can further include high load situation in a specific area and general high load situation.

[0092] Step 104: Manage the service scheduling of off-net roaming users based on the first information, the second information, and the third information.

[0093] In actual application, the first network device manages the service scheduling of off-net roaming users based on the first information (corresponding to the perspective of roaming user measurement data based on the MDT technology), the second information (corresponding to the perspective of off-net user service scheduling management), and the third information (corresponding to the perspective of network optimization).

[0094] In the service scheduling method provided by the present application, the first network device receives the first information sent by the terminal, where the first information is used to determine the minimized drive test information; receives the second information sent by the second network device, where the second information indicates the list of services of the off-net roaming user priority scheduling type, and when the user corresponding to the terminal is an off-net roaming user, the user in the list includes the user corresponding to the terminal; obtains the third information, where the third information indicates the wireless load information of the first network device; manages the service scheduling of off-net roaming users based on the first information, the second information, and the third information; this method is applied to the off-net roaming scenario, solves the problem that the service scheduling management of off-net roaming users cannot be refined when accessing the home network, occupies the resources of home network users, and affects the service quality of users, realizes the refined management of the service scheduling of off-net roaming users accessing the home network, and improves the network service quality.

[0095] In one embodiment, step 104 manages the service scheduling of off-net roaming users based on the first information, the second information, and the third information, including:

[0096] If the third information indicates that the wireless load of the first network device belongs to the first load range, set the services of the off-net roaming users in the list whose service priorities need to be improved and the services of the on-net users of the second network device to the same priority.

[0097] In practical applications, the wireless load of the first network device belongs to the first load range, corresponding to a low load situation. In this regard, in this application, the services of the off-net roaming users in the list whose service priorities need to be improved and the services of the on-net users of the second network device are set to the same priority. At this time, the service priorities of the off-net roaming users in the list whose service priorities need to be improved and the on-net users are the same, ensuring the service experience.

[0098] In one embodiment, step 104 manages the service scheduling of off-net roaming users based on the first information, the second information, and the third information, including:

[0099] If the third information indicates that the wireless load of the first network device belongs to the second load range, set the services of those who require improved voice and / or SMS services in the list and the services of the on-net users of the second network device to the same priority.

[0100] In practical applications, the wireless load of the first network device belongs to the second load range, corresponding to a medium load situation. In this regard, in this application, the services of those who require improved voice and / or SMS services in the list and the services of the on-net users of the second network device are set to the same priority. At this time, the priorities of the off-net roaming users who require improved voice and / or SMS services in the list and the on-net users are aligned, ensuring the voice and / or SMS service experience.

[0101] In one embodiment, the service scheduling method further includes:

[0102] Obtain the fourth information, where the fourth information indicates the wireless air interface resource information of the first network device;

[0103] Based on the fourth information, determine the scheduling order of the remaining services in the list.

[0104] In practical applications, the wireless air interface resource information includes, but is not limited to, the number of remaining resource blocks (RB), interference, etc.

[0105] In practical applications, the wireless load of the first network device belongs to the second load range, corresponding to a medium load situation. In this regard, in this application, for other types of data services except for voice and / or SMS services, based on the wireless air interface resource information, the first network device dynamically determines the scheduling order. Next, as Figure 4 shown, taking the uplink as an example:

[0106] The list indicating the service types with priority scheduling for off-net roaming user A indicates that the uplink live service data needs to be given a higher priority. For the uplink data request of off-net roaming user A, the first network device (such as a base station) determines the scheduling type of the user (such as off-net roaming user A). If it is an uplink live service (identifiable by protocol 5QI 71-74), at this time, it is first determined whether there is an uplink demand from the users of this network. Further, perform the relevant operations for scheduling users: if there is an uplink demand from the users of this network, schedule with priority; if there is no uplink demand from the users of this network, then schedule the time-frequency resources of the Physical Uplink Shared Channel (PUSCH) with less interference in the remaining RB resources to off-net roaming user A whose "uplink live service data needs to be given a higher priority", and the off-net roaming users without additional demands are next. Further, select the Modulation and Coding Scheme (MCS) and allocate Demodulation Reference Signal (DMRS) resources for the users.

[0107] In one embodiment, step 104 manages the service scheduling of off-net roaming users based on the first information, the second information, and the third information, including:

[0108] If the third information indicates that the radio load of the first network device in the first area belongs to the third load range, set the priorities of the voice and / or SMS services of the users of this network of the second network device, the voice and / or SMS services of off-net roaming users, the remaining services of the users of this network, and the remaining services of off-net roaming users to decrease in sequence.

[0109] In practical applications, when the radio load of the first network device in the first area belongs to the third load range, corresponding to the high-load situation in a specific area, for this, this application sets the priorities of the voice and / or SMS services of the users of this network of the second network device, the voice and / or SMS services of off-net roaming users, the remaining services of the users of this network, and the remaining services of off-net roaming users to decrease in sequence. At this time, the data service performs the initial scheduling priority setting, for example: voice and SMS of users of this network > voice and SMS of off-net users > other data services of users of this network > other data services of off-net users; for access, retransmission and other signaling services, the users of this network are high-priority services and are guaranteed with priority.

[0110] In one embodiment, when the radio load of the first network device in the first area belongs to the third load range, corresponding to the high-load situation in a specific area, for this, the first network device can also perform the handover or reselection of off-net roaming users to other cells / frequency points. In this way, when off-net roaming users are concentratedly distributed, occupy a large amount of resources, and squeeze the users of this network, this application performs the handover or reselection of off-net roaming users to other cells / frequency points to reduce resource consumption.

[0111] In one embodiment, step 104 manages the service scheduling of off-net roaming users based on the first information, the second information, and the third information, including:

[0112] If the third information indicates that the wireless load of the first network device in multiple regions belongs to the third load range, set the priority of the services of off-net roaming users in the list to be lower than the threshold priority.

[0113] In practical applications, when the wireless load of the first network device in multiple regions belongs to the third load range, corresponding to the generally high load situation, for this, the present application sets the priority of the services of off-net roaming users in the list to be lower than the threshold priority, that is, performs low-priority scheduling for off-net roaming users and does not guarantee the user experience of off-net roaming users.

[0114] In one embodiment, step 104 manages the service scheduling of off-net roaming users based on the first information, the second information, and the third information, including:

[0115] Based on the first information, obtain the fourth information, and the fourth information indicates a user profile including at least one of location, time, and service type;

[0116] Manage the service scheduling of off-net roaming users based on the fourth information, the second information, and the third information.

[0117] In practical applications, the core network A receives the list of service types with priority scheduling for off-net roaming users and feeds back the situation to the first network device, that is, the wireless network. The wireless network performs priority sorting based on the network load and the user profile. In this way, the wireless network performs priority sorting based on at least one of location, time, and service type, and further combines the network load.

[0118] In one embodiment, step 101 receives the first information sent by the terminal, including:

[0119] Receive the first signaling sent by the terminal. The first field of the first signaling includes the first information. The first field is used to group user data of different operators, and the group identifiers of the home network users and off-net roaming users of the second network device are different.

[0120] In practical applications, the terminal reports measurement data, and the first network device forms an M1-M9 measurement report based on the measurement data. Further, the present application groups the measurement data of home network and off-net users. Since MDT does not distinguish between home network and off-net users, it is not easy to distinguish them separately in the case of a large amount of data and cannot be refined. The present application can add corresponding fields to the MDT-related acquisition signaling, as follows:

[0121]

[0122] Add new fields in MDT-Configuration for grouping user data of different operators:

[0123]

[0124] Add fields MDTPLMNGroup and Plmnsubgroup[N] to group-differentiate user data of different operators. In this way, refined differentiation between home network and foreign network users is achieved.

[0125] In one embodiment, step 102 receives second information sent by a second network device, including:

[0126] Receive a first message sent by a second network device. The corresponding fields of the first message include second information, and the corresponding fields include a user identifier and a service identifier of a service with a priority scheduling type.

[0127] In actual application, Core Network B sets priority recommendations based on foreign network roaming users, establishes a list of services with a priority scheduling type for foreign network roaming users, and can add corresponding information fields in Namf_Communication_N1MessageNotify to identify users and feedback to Core Network A. The field identification is shown as follows:

[0128] VIPUEpriority'00100000 00’B

[0129] Among them, each Bit can represent the priority requirements of different services, and corresponding rules can be set, such as:

[0130] '10000000 00’B indicates that the voice message service (5QI1) is recommended to increase the priority;

[0131] '01000000 00’B indicates that the live broadcast service (5QI 71~74) is recommended to increase the priority;

[0132] '11000000 00’B indicates that the voice message service (5QI1) and the live broadcast service (5QI 71~74) are recommended to increase the priority.

[0133] The embodiment of the present application also provides a service scheduling method, which is applied to a second network device, as Figure 5 shown. The method includes:

[0134] Step 301: When the second network device communicates with a third network device, receive second information sent by the third network device. The second information indicates a list of services with a priority scheduling type for foreign network roaming users.

[0135] In actual application, Core Network A notifies Core Network B of the parameters of off-net roaming users (including but not limited to PLMN, IMSI, GUAMI, DNN, S-NSSAI, TAI), and Core Network B completes the corresponding network element routing addressing selection and communicates with Core Network A.

[0136] Based on the priority recommendation set for off-net roaming users, Core Network B establishes a list of services of the off-net roaming user priority scheduling type.

[0137] Step 302: Send the second information to the first network device.

[0138] In actual application, Core Network B feeds back the second information indicating the list of services of the off-net roaming user priority scheduling type to Core Network A.

[0139] In one embodiment, receiving the second information sent by the third network device in step 301 includes:

[0140] Receiving the first message sent by the third network device, the corresponding fields of the first message include the second information, and the corresponding fields include the user identifier and the service identifier of the service of the priority scheduling type.

[0141] In one embodiment, sending the second information to the first network device in step 302 includes:

[0142] Sending the first message to the first network device.

[0143] In actual application, Core Network B can add the corresponding information field in Namf_Communication_N1MessageNotify to identify the user and feed it back to Core Network A.

[0144] Among them, the field identification is shown as follows:

[0145] VIPUEpriority'00100000 00’B

[0146] Among them, each Bit bit can represent the priority requirements of different services, and corresponding rules can be set, such as:

[0147] '10000000 00’B indicates that the voice message service (5QI1) is recommended to increase the priority;

[0148] '01000000 00’B indicates that the live broadcast service (5QI 71-74) is recommended to increase the priority;

[0149] '11000000 00’B indicates that the voice message service (5QI1) and the live broadcast service (5QI 71-74) are recommended to increase the priority.

[0150] In one embodiment, before receiving the second information sent by the third network device in step 301, it includes:

[0151] When the second network device and the third network device are interoperable, request the third network device to enable the minimized drive test function for the user.

[0152] In actual application, the core network of operator A and the core network of operator B interoperate with the information of off-net roaming users, and the core network of operator A requests the core network of operator B to enable the MDT function for the user.

[0153] The embodiment of the present application also provides a service scheduling method, which is applied to the third network device, as Figure 6 shown, the method includes:

[0154] Step 401: When the second network device and the third network device are interoperable, send the second information to the second network device, and the second information indicates the list of services of the off-net roaming user priority scheduling type.

[0155] In actual application, core network A notifies core network B of the off-net roaming user parameters, and core network B completes the corresponding network element routing address selection and interoperates with core network A. Among them, the off-net roaming user parameters include Public Land Mobile Network (PLMN) parameters, Globally Unique AMF Identifier (GUAMI), Data Network Name (DNN), Single Network Slice Selection Assistance information (S-NSSAI), and Tracing Area Identity (TAI).

[0156] Based on the priority recommendation set for the off-net roaming user, core network B establishes a list of services of the off-net roaming user priority scheduling type, and core network B feeds back the second information indicating the list of services of the off-net roaming user priority scheduling type to core network A.

[0157] In one embodiment, sending the second information to the second network device in step 401 may include:

[0158] Send a first message to the second network device, and the corresponding field of the first message includes the second information, and the corresponding field includes the user identifier and the service identifier of the service of the priority scheduling type.

[0159] The core network B can add corresponding information fields to identify the user in Namf_Communication_N1MessageNotify and feedback to the core network A.

[0160] Among them, the field identification is shown as follows:

[0161] VIPUEpriority'00100000 00’B

[0162] Among them, each Bit can represent the priority requirements of different services, and corresponding rules can be set, such as:

[0163] '10000000 00’B means that the voice message service (5QI1) is recommended to increase the priority;

[0164] '01000000 00’B means that the live broadcast service (5QI 71~74) is recommended to increase the priority;

[0165] '11000000 00’B means that the voice message service (5QI1) and the live broadcast service (5QI 71~74) are recommended to increase the priority.

[0166] In an embodiment, before sending the second information to the second network device in step 401, it may include:

[0167] In the case where the second network device communicates with the third network device, authorize the second network device to request the user to enable the minimized drive test function.

[0168] In practical applications, as Figure 7 shown, the process of whether the third network device authorizes the second network device to request the user to enable the minimized drive test function is as follows:

[0169] Step 501: The home network and off-net users access the core network of operator A.

[0170] Step 502: The core network of operator A and the core network of operator B exchange off-net roaming user information, and the core network of operator A requests the core network of operator B to enable the MDT function for the user.

[0171] Step 503: Determine whether the core network of operator B agrees to authorize the opening of the MDT function.

[0172] Step 504: If the core network of operator B does not agree to authorize the MDT function, execute the off-net roaming user low-priority scheduling strategy and do not guarantee the experience of off-net roaming users.

[0173] Step 505: If the core network of Operator B agrees to authorize the MDT function, for off-net users who support the MDT function and report it normally, perform Step 506: Analyze the network environment based on the MDT M1-M9 measurement report, and perform different scheduling management for on-net and off-net users.

[0174] In actual application, for off-net users who do not support the MDT function or for whom the MDT cannot be reported normally (users not authorized), perform low-priority scheduling for off-net roaming users.

[0175] In actual application, for off-net users who support the MDT function and report it normally, perform refined service scheduling management based on user and network conditions: Identify the data of off-net roaming users with MDT over a period of time to obtain a user portrait of location, time, and service type, and know the user distribution: the uplink and downlink traffic, transmission duration, QoS information, longitude and latitude information, etc. of the Packet Data Convergence Protocol (PDCP) measured by each UE per Data Radio Bearer (DRB).

[0176] In actual application, for off-net roaming users who report MDT test data, perform the following policies:

[0177] There are no restrictions on the signaling related to the access of off-net roaming users to ensure the access experience of off-net roaming users; the data scheduling signaling is differentially controlled based on the service type.

[0178] A service scheduling method proposed in this application is applied in the off-net roaming scenario to solve the problem that when off-net roaming users access this network, they cannot perform refined service scheduling management, occupy the resources of on-net users, and affect the user experience. A mechanism for the priority scheduling service type list of off-net roaming users is proposed. By adding a corresponding information field (VIPUEpriority) to identify users in Namf_Communication_N1MessageNotify, setting priority rules (the rules can be formulated based on the actual service situation), and adjusting according to the network situation and the list mechanism; it is proposed to add MDTPLMNGroup and Plmnsubgroup[N] fields in MDT-configuration to group the data of users of different operators. Since MDT does not distinguish between on-net and off-net users, it is not easy to distinguish them separately in the case of a large amount of data and cannot be refined and distinguished for processing. Therefore, the measurement data of on-net and off-net users can be grouped.
