Background

Currently, the process of accessing a network and establishing service transmission by a terminal device includes: carrier access and service connection are established in two stages. In the carrier access phase, the terminal device may select and access a corresponding carrier by cell search, and use the base station where the carrier is located as a serving base station of the terminal device. In the service connection establishment phase, the terminal equipment firstly sends service request information to the service base station, and the service base station forwards the service request information to the core network equipment, so that signaling connection from the terminal equipment to the core network equipment is established. Then, through a session establishment flow, a data plane channel of the session is established between the terminal device and the serving base station, the core network, and user plane data transmission of the service of the terminal device is carried.

In the carrier access phase, the terminal device generally selects and accesses the carrier with the largest signal strength. However, different types of services, such as voice services and data services, which can be initiated by the terminal device, have different carriers required by the different types of services. Therefore, the service requirement of the terminal device may not be satisfied only by determining the carrier accessed by the terminal device according to the magnitude of the signal strength.

Detailed Description

With the development of the mobile internet, the application of the 5G network is also maturing. Compared with a 4th generation (4G) network, the 5G network not only considers the connection between people, but also between people and objects, and the 5G network supports the low-power-consumption wide coverage of the enhanced mobile broadband represented by the virtual reality service and the connection between mass Internet of things and the service in three large scenes represented by the industrial Internet and the Internet of vehicles, such as low time delay and high reliability. The service under different scenes has difference in requirements on data transmission rate and data transmission delay. Therefore, differentiated requirements are also put on the traffic transmission capability of the network.

The service transmission capability of the network may be embodied as the service transmission capability of a carrier of the network device. The network device may support the network. After the terminal device accesses the network, the terminal device may transmit the service data with the network device through the carrier. For example, transmission of voice traffic and data traffic may be performed.

When the terminal device needs to access a carrier or initiate a service request, the terminal device generally accesses the carrier with the maximum signal strength, and initiates the service request on the carrier after successfully accessing the carrier, thereby establishing transmission of service data.

However, the terminal device generally initiates different types of services, and the characteristic parameters of the different types of services are different. Moreover, the service support capabilities of different carriers also differ. Therefore, the following problems may exist in determining the access carrier of the terminal device according to the signal strength of the carrier:

problem 1, the carrier with the maximum signal strength does not support the service type initiated by the terminal device. For example, the carrier with the largest signal strength only supports data services, but the service type initiated by the terminal device is voice services.

Problem 2, the load capacity of the carrier and the transmission resources are limited. That is, the number of terminal devices accessible to the carrier is limited and the configured bandwidth is limited. If the low-speed service uses the carrier supporting the high-speed service for data transmission, it may occupy more transmission resources, which may result in that the subsequent high-speed service cannot normally perform data transmission, and affect the user use.

In view of this, an embodiment of the present application provides a carrier determining method, including: receiving a carrier wave which is used for triggering the terminal equipment to be accessed and is determined for the terminal equipment; determining the terminal type of the terminal equipment, wherein the terminal type of the terminal equipment is determined according to the service characteristic parameters of the terminal equipment in a first preset time period; and determining a target carrier accessed by the terminal equipment in a second preset time period according to the terminal type of the terminal equipment, wherein the second preset time period is behind the first preset time period.

The method provided by the embodiment of the application is described in detail below with reference to the attached drawings.

The technical solution of the embodiment of the present application may be applied to any communication system supporting communication, and the communication system may be a 3GPP high frequency wireless communication system, for example, a 5G mobile communication system, a New Radio (NR) system, an NR vehicle-to-electrical (V2X) system, and other next generation communication systems, and may also be a non-3 GPP communication system, without limitation. The following describes a method for determining antenna parameters according to an embodiment of the present application, with reference to fig. 1 as an example.

It should be noted that the communication system described in the embodiment of the present application is for more clearly illustrating the technical solution of the embodiment of the present application, and does not constitute a limitation to the technical solution provided in the embodiment of the present application, and as a person having ordinary skill in the art knows along with the evolution of the communication system and the appearance of other communication systems, the technical solution provided in the embodiment of the present application is also applicable to similar technical problems.

Fig. 1 is a schematic diagram illustrating a communication system according to an embodiment of the present application. As shown in fig. 1, the communication system may include a plurality of network devices (e.g., network device 1 and network device 2, network device 3) and terminal devices. The terminal device may be communicatively coupled to the plurality of network devices. The carrier determining device is used for determining carriers to be accessed for terminal equipment in a preset area, and can perform information interaction with each network equipment respectively. The carrier waves in the preset area and the identification information of the network equipment are preset in the carrier wave determining device.

In fig. 1, information interaction interfaces exist between the carrier determining apparatus and the plurality of network devices in the preset area, and the information interaction interfaces may be used for information interaction between the network devices and other network devices, and between the network devices and the carrier determining apparatus. Each network device is configured with one or more carriers. For example, network device 1 may be configured with carrier 1 and carrier 2, network device 2 may be configured with carrier 3, and network device 3 may be configured with carrier 4 and carrier 5.

In one example, network device 1 and network device 2 in fig. 1 may be located in the same coverage area.

The same coverage area may refer to an area where the same wireless signal coverage exists. The same coverage area can be formed by a plurality of same coverage areas, and the same coverage areas can form a same coverage area information base. The co-coverage area information base may include an identification of each co-coverage area and an identification of a carrier included in each co-coverage area. The same coverage area identifier may be an identifier of a network device in which any one carrier included in the same coverage area is located.

For example, in connection with fig. 1, network device 1 and network device 2 are located in the same coverage area. That is, the carrier 1, the carrier 2, and the carrier 3 are carriers in the same coverage area. The carrier 4 and the carrier 5 of the network device 3 are carriers of the same coverage area. The co-coverage area information base in the preset area may be as shown in table 1.

TABLE 1

Same coverage area identification	Carrier identification contained in same coverage area
		Network device 1	Carrier 1, carrier 2, carrier 3
Network device 3	Carrier 4, carrier 5,

It should be noted that, if two same coverage areas contain the same carriers and the same coverage area identifiers are different, any one of the same coverage area identifiers is reserved, and the other same coverage area identifier is deleted, thereby avoiding the situation that the same coverage area corresponds to different same coverage area identifiers.

The following describes a method for determining carriers in the same coverage area:

the method 1 is that whether two carriers are the carriers in the same coverage area is calculated according to the azimuth angle parameters of the carriers or the longitude and latitude of the network equipment where the carriers are located.

For example, if the difference between the azimuth angles of two carriers is smaller than the preset angle threshold, the two carriers are carriers in the same coverage area.

For another example, the distance between the two network devices is calculated according to the longitude and latitude of the network device where the two carriers are located, and if the distance between the two network devices is smaller than the preset distance threshold, the two carriers are carriers in the same coverage area.

And 2, determining whether the multiple carriers are the carriers in the same coverage area according to the identifiers of the carriers in the measurement reports reported by the multiple terminal devices and the signal strength values of the carriers.

The measurement report of the terminal device may include the identities of the multiple carriers and the signal strength value of each carrier. The identity of the carrier is used to uniquely identify a carrier. For any carrier contained in the measurement report, determining the average value of the signal strength values of the carrier contained in the multiple measurement reports as the signal strength average value of the carrier; if the difference between the signal strength mean values of any two carriers included in the measurement report is smaller than the preset signal strength threshold, the two carriers are carriers in the same coverage area.

For example, the measurement report reported by the terminal device 1 includes the identifier of the carrier 1 and the signal strength value a of the carrier 1, the identifier of the carrier 2 and the signal strength value b of the carrier 2, and the identifier of the carrier 3 and the signal strength value c of the carrier 3, and the measurement report reported by the terminal device 2 includes the identifier of the carrier 1 and the signal strength value a1 of the carrier 1, the identifier of the carrier 2 and the signal strength value b1 of the carrier 2. That is, the measurement reports reported by terminal device 1 and terminal device 2 both include the identifier of carrier 1 and the identifier of carrier 2. The signal strength average value of the carrier 1 is (a + a1)/2, and the signal strength average value of the carrier 2 is (b + b 1)/2.

After determining that a plurality of carriers with the same coverage area exist according to the above method, all the same-coverage-area identifiers in the preset area and the carrier identifier included in each same-coverage-area can be counted, so that the same-coverage-area information base of the preset area can be obtained.

Fig. 4 provides a carrier determination method for an embodiment of the present application, and as shown in fig. 4, the method includes:

step 401, the carrier determining apparatus receives first request information from a terminal device.

The carrier determining apparatus may be the carrier determining apparatus in fig. 2. The terminal device may be the terminal device in fig. 1 or fig. 2.

The first request message may be used to trigger the carrier determining apparatus to determine a carrier to be accessed for the terminal device. For example, the first request message may be a service request message or a carrier access request message.

Specifically, when the terminal device is in the carrier access phase, the first request information is carrier access request information, and the first request information may include an identifier of the terminal device; if the terminal device and the network device have established a communication connection, when the terminal device initiates a service request, the first request information may be service request information, and the first request information may include an identifier of the terminal device, an identifier of a service type, an expected value of a data transmission rate, and an expected value of a data transmission delay. The expected data transmission rate value may be used to characterize a data transmission rate required for transmitting the data service, and the expected data transmission delay value may be used to characterize a lowest data transmission delay for transmitting the data service.

It should be noted that, in the embodiment of the present application, the data transmission data may be an uplink data transmission rate, and may also be a downlink data transmission rate, which is not limited.

The identifier of the terminal device may be used to identify the terminal device, for example, the identifier of the terminal device may be a Media Access Control (MAC) address of the terminal device. The identification of the service type may be used to identify the service type of the terminal device. The identification of the type of service may be a number, a letter, or a combination of a number and a letter. For example, when the service type parameter is a first character (for example, 1), it indicates that the service of the terminal device is a voice service; when the service type parameter is the second character (for example, 2), it indicates that the service of the terminal device is a data service. The expected data transmission rate value and the expected data transmission delay value reflect the service performance requirements of the terminal equipment for the terminal equipment, and different services correspond to different expected data transmission rate values and different expected data transmission delay values.

In a possible implementation manner, when the terminal device sends the first request information to the anchor point device through the anchor point carrier under the condition that the carrier determination apparatus and the anchor point device are independent of each other. Accordingly, the anchor point device may forward the first request information to the carrier determination apparatus after receiving the first request information from the terminal device.

In yet another possible implementation manner, when the carrier determination apparatus is an anchor device or an apparatus in an anchor device, the terminal device may directly send the first request information to the carrier determination apparatus. Accordingly, the carrier determining apparatus receives the first request information from the terminal device.

Step 402, the carrier determining device determines the terminal type of the terminal equipment.

The terminal type carrier determining device of the terminal equipment determines the terminal type carrier according to the service characteristic parameters of the terminal equipment in the first preset time period.

The first preset time period may be a time period before the current time and having a preset time length. The duration of the first preset time period may be set according to needs, and may be, for example, 24 hours, 12 hours, and the like, without limitation.

The service characteristic parameter of the terminal device may reflect the requirement of the service of the terminal device on the data transmission performance and the service preference of the terminal device. For example, the service characteristic parameter of the terminal device may include a service type parameter, a data transmission rate of the data service, a data transmission delay, and the like.

The service types can include voice service and data service; the service type parameter indicates whether the service of the terminal equipment in the first preset time period is voice service or data service. For example, when the service type parameter is a first character (for example, 1), it indicates that the service of the terminal device is a voice service; when the service type parameter is the second character (for example, 2), it indicates that the service of the terminal device is a data service.

The data transmission rate of the data service may refer to a data transmission rate of the data service in each sub-period. The data transmission delay may refer to a data transmission delay of the data traffic in each sub-period. The data transmission rate and the data transmission delay of the data service of the terminal device may be statistically obtained by the service device of the terminal device.

It should be noted that the unit time period is a period of the service device counting parameters such as data transmission rate and data transmission delay of the data service, and the length of the unit time period may be less than or equal to the length of one sub-time period of the first preset time period. That is, at least one unit period is included in one sub-period. The data transmission rate of one sub-period may be an average of the data transmission rates of at least one unit period included in the sub-period. The data transmission delay in one sub-period may be an average value of data transmission delays of at least one unit period included in the sub-period.

It should be supported that when the terminal device is in an idle state without service data transmission, the service type parameter, the data transmission rate, and the data transmission delay of the terminal device are all 0.

The method for acquiring the service characteristic parameters of the terminal equipment in the first preset time period by the carrier determining device comprises the following steps: the carrier wave determining device sends a first parameter request message to all network equipment in a preset area, and the first parameter request message is used for requesting to acquire service characteristic parameters of terminal equipment; all network equipment in a preset area respectively sends a first parameter indication message to a carrier wave determining device, wherein the first parameter indication message can carry a terminal equipment identifier and a corresponding service characteristic parameter;

the following describes a method for acquiring a service type parameter of a terminal device:

method 1, the service type parameter of the terminal device may be carried in the service request information of the terminal device.

For example, the terminal device may send service request information to the serving device. Correspondingly, the service equipment receives the service request information from the terminal equipment. The service request information may include a service type parameter of the terminal device.

Method 2, the service type parameter of the terminal device may be stored in the core network device.

For example, after receiving the service request of the terminal device, the service device of the terminal device may send service type request information to the core network device. The service type request message may include an identifier of the terminal device, a service identifier, a service data packet type of the terminal device, and a data transmission protocol type of the terminal device and the service device. After receiving the service type request information from the service device, the core network device may determine a corresponding service type parameter according to a pre-configured mapping relationship. The mapping relationship may include a correspondence relationship between a service data packet type, a data transmission protocol type of the terminal device and the service device, and a service type. The core network device feeds back service type indication information to the service device, where the service type indication information may include an identifier of the terminal device, a service identifier, and a service type parameter.

Step 403, the carrier determining device determines a target carrier accessed by the terminal device in the second preset time period according to the terminal type of the terminal device.

And the second preset time period is positioned after the first preset time period. The target carrier and the anchor carrier are the same coverage area carrier. The same coverage area carrier can refer to the above description, and is not described herein again.

The specific implementation method of step 403 may refer to the following description, which is not repeated.

Based on the technical scheme of fig. 4, after the carrier determining apparatus receives the first request information from the terminal device, the carrier determining apparatus may be triggered to determine a carrier to be accessed for the terminal device. And the carrier wave determining device determines the terminal type of the terminal equipment according to the service type parameter of the terminal equipment in the first preset time period. The service type parameter of the terminal device can reflect the requirement of the service of the terminal device for the data transmission performance in the time period, and can also reflect the service type preference of the terminal device in the time period. Therefore, the carrier determining device can accurately determine the target carrier accessed by the terminal device in the second preset time period according to the terminal type of the terminal device.

In a possible implementation manner, the specific implementation manner of step 402 in fig. 4 may include the following manner 1 and manner 2.

In the method 1, the carrier determining apparatus may divide the first preset time period into a plurality of sub-time periods, and determine the service type parameter of the terminal device in each sub-time period. And the carrier wave determining device determines the terminal type of the terminal equipment according to the service characteristic parameters of the terminal equipment in the plurality of sub-time periods.

In one example, if the ratio between the number of the first type sub-period and the number of the plurality of sub-periods is greater than a preset ratio, the terminal device is a first type terminal device; if the ratio of the number of the second type sub-time periods to the number of the plurality of sub-time periods is greater than the preset ratio, the terminal equipment is second type terminal equipment; if the ratio of the number of the third type sub-time periods to the number of the plurality of sub-time periods is greater than the preset ratio, the terminal equipment is third type terminal equipment; and if the ratio of the number of the first type sub-time periods to the number of the plurality of sub-time periods, the ratio of the number of the second type sub-time periods to the number of the plurality of sub-time periods, and the ratio of the number of the third type sub-time periods to the number of the plurality of sub-time periods are smaller than the preset ratio, the terminal equipment is fourth type terminal equipment.

The first type time period may refer to a sub-time period in which the service type of the terminal device in the multiple sub-time periods is a voice service. The second type time period may refer to a sub-time period in which the service type of the terminal device in the multiple sub-time periods is a data service, the data transmission rate of the data service is greater than a preset second rate threshold, and the data transmission delay is less than a preset second delay threshold (also referred to as a high-speed low-delay data service). The third type time period may refer to a sub-time period in which the service type of the terminal device is a data service, the data transmission rate of the data service is greater than a preset second rate threshold, and the data transmission delay is greater than or equal to a preset second delay threshold (also referred to as a non-delay sensitive high-speed data service) in the plurality of sub-time periods. When the service type of the terminal device is data service and the data transmission rate of the data service is less than or equal to a preset second rate threshold (which may also be referred to as low-speed data service), the sub-period is a fourth type sub-time end.

It should be noted that the number of the divisions of the multiple sub-periods and the duration of the divisions may be set as required, for example, taking the duration of the first preset period as 24 hours, the first preset period may be divided into 120 sub-periods, and the duration of each sub-period is 12 minutes. The preset second speed threshold and the preset second delay threshold can be set according to needs, and are not limited.

It should be noted that, when the service type of the terminal device in a sub-period includes both voice service and data service, the sub-period may be used as the first type period to preferentially guarantee the voice service.

In the mode 2, the carrier determining apparatus may determine the type of the terminal device according to the duration of the voice service in the first preset time period and the durations of different data services.

In one example, when the duration of the voice service of the terminal device in the first preset time period is greater than the duration of the data service, the carrier determining apparatus may determine that the terminal device is a first type terminal device; when the duration of the data service of the terminal equipment in the first preset time period is longer than the duration of the voice service, and the duration of the high-speed low-delay data service is longer than the durations of the non-delay sensitive high-speed data service and the low-speed data service, the carrier determining device can determine that the terminal equipment is the second type terminal equipment; when the duration of the data service of the terminal device in the first preset time period is longer than the duration of the voice service, and the duration of the non-delay sensitive high-speed data service is longer than the durations of the high-speed low-delay data service and the low-speed data service, the carrier determining device may determine that the terminal device is a third type terminal device; when the duration of the data service of the terminal device in the first preset time period is longer than the duration of the voice service, and the duration of the low-speed data service is longer than the durations of the high-speed low-delay data service and the non-delay sensitive high-speed data service, the carrier determining device may determine that the terminal device is a fourth type terminal device.

In a possible embodiment, with reference to fig. 4, as shown in fig. 5, the method provided in this embodiment of the present application may further include:

step 501, a carrier determining device obtains a characteristic parameter of each carrier in one or more carriers having the same coverage area as an anchor carrier.

The characteristic parameter of the carrier may include one or more of a service type identifier of the carrier, a data transmission rate capability of the carrier, and a data transmission delay capability of the carrier. The anchor carrier is a carrier accessed by the terminal equipment at the current time of the terminal equipment. The target carrier is one of the one or more carriers.

The data transmission rate capability of the carrier may refer to a maximum service data transmission rate supported by the carrier. The data transmission rate capability of a carrier is related to the bandwidth, spectral efficiency of the carrier. Due to differences in signal transmission techniques supported by different carriers, the spectral efficiency of each carrier is also different. For example, compared with a 4G carrier, a 5G carrier supports technologies such as massive MIMO, high-order modulation, and carrier aggregation, and the spectrum efficiency is greatly improved. The transmission bandwidths supported by different carriers also differ, for example, the bandwidth of a 4G carrier is 20MHz at most, and the bandwidth of a 5G carrier is 100MHz (below 6GHz frequency) or 400MHz (above 6GHz frequency) at most.

The data transmission delay capability of the carrier may refer to a minimum data transmission delay supported by the carrier. The data transmission delay capability of the carrier is related to the low delay transmission technology supported by the carrier. For example, the 5G carrier may reduce the service transmission delay by supporting technologies such as a shorter time slot structure and resource pre-scheduling, so that the air interface transmission delay is reduced from 4ms to 1ms, and the requirement of the delay sensitive service is met.

In one possible implementation, the carrier determining apparatus may obtain one or more carriers having the same coverage area as the anchor carrier from the same coverage area information base. The information of the same coverage area may be configured in advance in the carrier determining apparatus, or may be acquired by the carrier determining apparatus from another device, for example, may be acquired from a core network device, without limitation. The information base of the same coverage area may refer to the above description, and is not repeated.

For example, in conjunction with table 1 above, if the anchor carrier is carrier 1, then the one or more carriers may include carrier 1, carrier 2, and carrier 3.

The method for the carrier determination device to obtain the characteristic parameters of each of the one or more carriers having the same coverage area as the anchor carrier may be: the carrier determining device sends a second parameter request message to the anchor point device and network devices where one or more carriers having the same coverage area as the anchor point carrier are located, and the second parameter request message is used for acquiring the characteristic parameters of each carrier; and the anchor point equipment and the network equipment where one or more carriers with the same coverage area as the anchor point carrier are located respectively send a second parameter indication message to the carrier wave determining device, wherein the second parameter indication message carries the characteristic parameters of each carrier wave.

Step 502, the carrier determining device determines the carrier type according to the characteristic parameters of the carrier.

The carrier type is used for representing the service support capability of the carrier.

In a possible implementation manner, the carrier determining apparatus may divide the carrier into multiple types according to the service type supported by the carrier, the data transmission rate capability of the carrier, and the data transmission delay capability of the carrier.

In one example, if the service type identifier of the carrier is used to indicate a voice service, and the data transmission rate of the carrier is greater than a preset first rate threshold, the carrier is a first voice carrier; if the service type identifier of the carrier is used for indicating voice service and the data transmission rate of the carrier is less than or equal to a preset first rate threshold, the carrier is a second voice carrier; if the service type identifier of the carrier is used for indicating a data service, and the data transmission rate of the carrier is greater than a preset first rate threshold, and the data transmission delay of the carrier is less than a preset first delay threshold, the carrier is a first data carrier; if the service type identifier of the carrier is used for indicating the data service, the data transmission rate of the carrier is greater than a preset first rate threshold value, and the data transmission delay of the carrier is greater than or equal to a preset first delay threshold value, the carrier is a second data carrier; and if the service type identifier of the carrier is used for indicating the data service and the data transmission rate of the carrier is less than or equal to a preset first rate threshold, the carrier is a third data carrier.

The preset first rate threshold and the preset first time delay threshold can be set according to needs, and are not limited.

It should be noted that the number of the first voice carrier, the second voice carrier, the first data carrier, the second data carrier, and the third data carrier in the one or more carriers may be one or more, and may also be 0.

Based on the implementation manner of fig. 5, the carrier determination apparatus may divide the carriers into carriers of different types according to the service support capability of the carriers, so as to subsequently configure carriers of corresponding types for different services.

In a possible implementation manner, when the first request information is carrier access request information, a specific implementation manner of the step 401 may be:

if the terminal type of the terminal equipment is the first type terminal equipment, determining candidate carriers accessed by the terminal equipment according to the first priority sequence; if more than one candidate carrier exists, determining the target carrier as the carrier with the minimum load in the candidate carriers; the first priority order is that the priority of the first voice carrier is greater than the priority of the second voice carrier.

If the terminal equipment is the second type terminal equipment, determining candidate carriers accessed by the terminal equipment according to the second priority order; if more than one candidate carrier exists, determining the target carrier as the carrier with the minimum load in the candidate carriers; the second priority order is that the priority of the first data carrier is higher than the priority of the second data carrier, and the priority of the second data carrier is higher than the priority of the third data carrier.

If the terminal equipment is the third type terminal equipment, determining candidate carriers accessed by the terminal equipment according to a third priority sequence; if more than one candidate carrier exists, determining the target carrier as the carrier with the minimum load in the candidate carriers; the third priority order is that the priority of the second data carrier is higher than the priority of the third data carrier, and the priority of the third data carrier is higher than the priority of the first data carrier.

If the terminal equipment is the fourth type terminal equipment, determining that the target carrier is the carrier with the minimum load in the candidate carriers; the fourth priority order is that the priority of the third data carrier is higher than the priority of the second data carrier, and the priority of the second data carrier is higher than the priority of the first data carrier.

In another possible implementation manner, when the first request information is service request information, if the terminal type of the terminal device is a first type terminal device, but the first request information is used for requesting a data service, the carrier determining device determines, according to the characteristic parameter of the data service, that the target carrier accessed by the terminal device is a carrier with the highest priority and the smallest load among the first data carrier, the second data carrier, and the third data carrier.

For example, if the expected data transmission rate of the data service is greater than the second rate threshold and the expected data transmission delay value is less than the second delay threshold, determining the candidate carriers accessed by the terminal device according to the second priority order; if the expected data transmission rate value of the data service is greater than the second rate threshold and the expected data transmission delay value is greater than or equal to the second delay threshold, determining candidate carriers accessed by the terminal equipment according to a third priority sequence; if more than one candidate carrier exists, determining the target carrier as the carrier with the minimum load in the candidate carriers; and if the expected data transmission rate value of the data service is less than or equal to the second rate threshold, determining candidate carriers accessed by the terminal equipment according to the fourth priority sequence, and if more than one candidate carrier exists, determining the target carrier as the carrier with the minimum load in the candidate carriers.

If the terminal type of the terminal device is any one of the second type terminal device, the third type terminal device and the third type terminal device, but the first request information is used for requesting a voice service, the carrier wave determining device determines a candidate carrier wave accessed by the terminal device according to the first priority order. And if more than one candidate carrier exists, determining the target carrier as the carrier with the minimum load in the candidate carriers.

In a possible embodiment, the method provided in the embodiment of the present application may further include: the carrier wave determining device sends first indication information to the terminal equipment. Correspondingly, the terminal equipment receives the first indication information from the carrier wave determining device.

The first indication information may be used to indicate a target carrier, or the first indication information may also be used to indicate the terminal device to access the target carrier. The first indication information may include an identification of the target carrier.

In a possible implementation manner, if the carrier determining apparatus is not the anchor point device or an apparatus in the anchor point device, the carrier determining apparatus may send second indication information to the anchor point device, where the second indication information carries the terminal device identifier and the target carrier identifier. Correspondingly, after receiving the second indication information from the carrier determining device, the anchor point device sends a first indication message to the terminal device corresponding to the terminal device identifier.

The target carrier and the anchor carrier may be the same carrier or different carriers.
