Detailed ways

In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

FIG. 1 shows a schematic diagram of a communication system to which the technical solution provided by the present application is applicable. The communication system may include an access network device 100 and a user equipment (User Equipment, UE) 200. Fig. 1 is only a schematic diagram, and does not constitute a limitation on the applicable scenarios of the technical solution provided by the present application.

The access network device 100 may be a transmission reception point (transmission reception point, TRP), a base station, a relay station, or an access point, etc. The access network device 100 may be an access network device in a 5G communication system or an access network device in a future evolution network; it may also be a wearable device or a vehicle-mounted device. In addition, it can also be: a base transceiver station (BTS) in a global system for mobile communication (GSM) or a code division multiple access (CDMA) network, or a broadband The NB (NodeB) in code division multiple access (wideband code division multiple access, WCDMA) can also be the eNB or eNodeB (evolutional NodeB) in long term evolution (long term evolution, LTE). The access network device 100 may also be a wireless controller in a cloud radio access network (cloud radio access network, CRAN) scenario. Hereinafter, the present application will take a base station as an example for description.

The user equipment 200 includes a personal digital assistant (PDA), a handheld device with a wireless communication function, a computing device or other processing equipment connected to a wireless modem, a vehicle-mounted device, a wearable device, user equipment in a 5G network or future A user equipment in an evolved public land mobile network (public land mobile network, PLMN) network, etc.

At present, during the process of establishing a communication connection between a user equipment and an access network device, the access network device will inquire about the carrier aggregation (Carrier Aggregation, CA) capability of the user equipment, and the user equipment will report the CA capability to the access network device, so that the access network device The network access device can control the user equipment to complete corresponding service access according to the CA capability of the user equipment.

The carrier aggregation capability refers to the capability of a UE to simultaneously transmit and receive data on two or more continuous or non-contiguous cells or carriers. The carrier aggregation capability includes the CA capability of the fourth generation (4th-Generation, 4G), or the CA capability of the fifth generation (5th-Generation, 5G), or the CA capability of 4G-5G, or the CA capability of 5G and 4G-5G CA capability, etc. The CA capability of 4G-5G refers to the Evolved Universal Terrestrial Radio Access New Air Interface Dual Connection (EUTRA-NR Dual Connection, EN-DC) capability, and the EN-DC capability refers to the 4G wireless access network and 5G New Air Interface (New Radio, NR ) dual connectivity capability. Alternatively, the carrier aggregation capability may also include the CA capability that needs to be reported in the next generation cellular mobile communication system and other mobile communication systems that will be developed subsequently. Among them, EUTRA is Evolved Universal Terrestrial Radio Access, and the full name of EUTRA is Evolved Universal Terrestrial Radio Access.

In the prior art, the UE can send the CA combination to the access network device based on the order of frequency bands (bands) inquired by the access network device, and based on the UE's own radio frequency hardware support and the maximum transmission capacity supported by the user equipment itself, so that the access network device The network device can configure the serving cell or the measurement gap according to the CA combination sent by the UE.

Wherein, the frequency band (band) inquired by the access network device may include a 4G band and a 5G band. For the convenience of introduction, below, B represents a 4G band, and N represents a 5G band. For example, 4G band EUTRA 1 is referred to as B1, band EUTRA 3 is referred to as B3, 5G bandNR1 is referred to as N1, and bandNR3 is referred to as N3.

If the bands queried by the access network device include 4G bands and 5G bands, the 4G bands queried by the access network device are B1, B3, B7, and B8 in sequence, and the 5G bands queried are N1 and N3 in sequence. If the radio frequency hardware of the user equipment can support the band inquired by the access network device, the user equipment needs to send the 4G-5G CA capability and the 5G CA capability to the access network device. Among them, the CA capability of 4G-5G includes the CA combination of 4G-5G, the CA combination of 4G-5G refers to the EN-DC capability, and the CA capability of 5G includes the NR-CA combination. However, due to the limitation of the maximum transmission capacity of 8K bytes of the CA combination supported by the user equipment itself, the total transmission capacity of the user equipment to send 4G-5G CA capabilities and 5G CA capabilities to the access network device at one time cannot exceed 8K bytes . That is to say, for example, if the user equipment sends 124 4G-5G CA combinations to the access network device, the transmission capacity occupied by the 124 4G-5G CA combinations is greater than 4K bytes, and the remaining transmission capacity is used to send 5G CA combinations. ability.

It should be noted that if the user equipment only needs to send the 4G-5G CA capability to the access network device, sending at most about 199 sets of 4G-5G CA combinations takes up 8K bytes of sending capacity. That is to say, limited by the maximum transmission capacity of 8K bytes of the CA combination supported by the user equipment itself, the number of CA combinations included in the 4G-5G CA capability sent by the user equipment is about 124-199.

In addition, when the user equipment sends the CA combination to the access network device, it needs to be based on the order of the frequency bands inquired by the network. Among the CA combinations included in the 4G-5G CA capability sent by the user equipment, the combination with the highest ranking is B1. CA combinations, followed by CA combinations with B3 in front, and so on, where CA combinations with B1 in front are, for example, B1-B3-B7-B8-N1, B1-B3-B7-B8-N3, B1-B3-B7 -N1, B1-B3-B7-N3, etc. In the current method for the user equipment to report the CA combination to the access network device, there is a case that the CA combination sent to the access network device is not the CA combination supported by the access network device.

For example, during the process of user equipment accessing China Unicom's access network equipment, the CA combination supported by China Mobile or China Telecom's access network equipment is reported to China Unicom's access network equipment. Even if the user equipment can successfully access the network, the access network equipment of China Unicom will not receive the important CA combination, so the access network equipment will not allocate these important CA combinations to the user equipment. The resources corresponding to the CA combination. Therefore, how to use the limited capacity to send the CA combination to the access network device becomes an urgent problem to be solved by those skilled in the art.

In order to solve the above technical problem, based on the communication system shown in FIG. 1 , the present application provides a method for transmitting a carrier aggregation capability. Referring to FIG. 2, FIG. 2 is a schematic flowchart of a method for reporting a carrier aggregation capability provided by an embodiment of the present application. The execution subject of this embodiment is a user equipment, and the method includes the following steps:

S201. Receive a capability query request sent by an access network device. The capability query request is used to query the carrier aggregation CA capability of the user equipment, and the capability query request carries a frequency band identifier.

Wherein, the capability inquiry request may be UECapability Inquiry, the identifiers of the bands carried in the UECapability Inquiry, for example, the identifiers B1, B3, B7, and B8 of the carried bands.

The frequency band carried in the capability query request may be the frequency band where the same-frequency frequency point configured by the access network device for the user equipment is located, for example: the frequency band where the frequency point of the serving cell currently accessed by the user equipment is located, and the access network device is the frequency band where the user equipment repeats The frequency band where the frequency point of the configured serving cell is located, etc.;

The frequency band where the access network device configures the user equipment for other frequency points except the same frequency frequency point, for example: the frequency band where the target frequency point for inter-frequency measurement is located, etc.; the frequency band where the frequency point is not configured for the user by the access network device; The frequency band where the frequencies of other access network devices adjacent to the access network device are located.

S202. Send device capability information to the access network device according to the capability query request. The device capability information includes the identifier of the first CA combination, the first CA combination includes carriers in the frequency band, and the first CA combination is the identity card of the user equipment. The CA combinations supported by both the operator's network and user equipment.

The user equipment may determine the carrier aggregation (Carrier Aggregation, CA) combination supported by the operator network and the user equipment according to the operator network to which the Subscriber Identity Module (SIM) card in the user equipment belongs.

Wherein, the SIM card can be understood as a key for the user equipment to access the mobile network. For the convenience of description, the SIM card and its evolution are collectively referred to as the SIM card in the embodiment of the present application. For example, the SIM card can be an identification card of a global system for mobile communications (GSM) digital mobile phone user, which is used to store the user's identification code and key, and supports the authentication of the user by the GSM system. For another example, the SIM card may also be a universal subscriber identity module (USIM), and may also be called an upgraded SIM card.

The user equipment manufacturer may pre-configure CA capability information in the user equipment before the user equipment leaves the factory, and the CA capability information configured in the user equipment may include CA combinations supported by multiple operators. The CA capability information may be stored in a memory (such as a non-volatile memory) of the user equipment.

Wherein, the CA capability information may include the identifier of each operator and the identifiers of the CA combinations supported by the corresponding operator.

In some implementations, the operator's identity may be the operator's PLMN. Among them, the PLMN consists of the MCC and the Mobile Network Code (MNC) of the country where the operator is located. Among them, MCC is uniformly allocated and managed by the International Telecom Union (ITU) worldwide, and is used to uniquely identify different countries in the global mobile communication system, with a total of 3 digits. For example, China's MCC is 460. MNC usually consists of 2 to 3 digits. The MNCs of different operators are different, and the MNCs of mobile networks of different standards of the same operator are also different.

In some embodiments, the identifier of the operator may be the MCC of the country where the operator is located. Among them, when the CA capability information of multiple operators is pre-configured in the user equipment, if the CA combination supported by operator A is not collected, the default CA combination configured in the country where operator A is located can be used as the CA supported by operator A combination. In this case, the MCC of the country where operator A is located is used as the identifier of operator A. That is, the CA capability information may include: the MCC of the country where the operator A is located and the identifier of the default CA combination configured for the country where the operator A is located.

The method for reporting the carrier aggregation capability provided in this embodiment is to receive a capability query request sent by an access network device. The capability query request is used to query the carrier aggregation CA capability of the user equipment. The capability query request carries the identification of the frequency band. According to the capability query request Send the device capability information to the access network device, the device capability information includes the identification of the first CA combination, the first CA combination includes the carrier in the frequency band, the first CA combination is the operator network and the user equipment to which the identity card of the user equipment belongs Commonly supported CA combinations. Because in the traditional reporting method, the user equipment reports the CA combination to the access network device based on the order of the frequency bands inquired by the network, there is a CA combination not supported by the access network device that is reported to the access network device. However, in this embodiment of the application, the device capability information reported by the user equipment includes the first CA combination identifier, and the first CA combination is a CA combination supported by both the operator network to which the user equipment's identification card belongs and the user equipment, to avoid The CA combination not supported by the access network device is reported to the access network device. Therefore, the CA combination supported by the access network device can be reported to the access network device by utilizing the limited sending capacity as much as possible.

Optionally, the device capability information includes identifiers of multiple first CA combinations, and the identifiers of the multiple first CA combinations are sorted according to priorities of the multiple first CA combinations.

In this embodiment, the pre-configured CA combination supported by the operator network in the user equipment corresponds to a priority, and the priority of the CA combination is set according to the importance of the CA combination supported by the operator network. For example, the user equipment must be connected to the network. The priority of the supported CA combinations is set to the highest.

In this embodiment, since the identifiers of the multiple first CA combinations are sorted according to the priorities of the multiple first CA combinations, it can be ensured that the user equipment reports important CA combinations to the access network device as much as possible.

Optionally, the capability query request is specifically used to query multiple CA capabilities of the user equipment;

The device capability information includes a plurality of identification sets respectively corresponding to various CA capabilities, each identification set includes identifications of a plurality of first CA combinations related to the corresponding CA capabilities, and the plurality of first CA combinations included in each identification set The identities are sorted by priority.

In this embodiment, the device capability information includes multiple identifier sets respectively corresponding to multiple CA capabilities. It should be noted that, when the access network device queries multiple CA capabilities of the user equipment, the user equipment may carry multiple CA capabilities in one UECapabilityInformation message.

When multiple CA capabilities are carried in one UECapabilityInformation message, the device capability information includes multiple identifier sets respectively corresponding to the multiple CA capabilities. For example, the device capability information includes an identifier set 1 corresponding to the 4G-5G CA capability and an identifier set 2 corresponding to the 5G CA capability, and the identifier set 1 includes identifiers of multiple first CA combinations related to the 4G-5G CA capability , the identification set 2 includes the identifications of multiple first CA combinations related to 5G CA capabilities, and the multiple first CA combinations included in the identification set 1 are sorted according to priority, and the multiple first CA combinations included in the identification set 2 Sort by priority.

Among them, the multiple first CA combinations included in each identification set are sorted according to priority, which means that among the multiple first CA combinations included in the identification set, which first CA combinations have the highest priority, these first CA combinations are sorted The higher the priority, the first CA combination with higher priority in each identification set is reported first. For example, due to the capacity limitation of the CA combination reported by the user equipment, if there are 124 first CA combinations related to the 4G-5G CA capability reported by the user equipment to the access network device, the 124 first CA combinations are sorted The top first CA combination is the first CA combination with the highest priority.

In this embodiment, since the identities of the multiple first CA combinations are sorted according to the priorities of the multiple first CA combinations from high to low, it can be ensured that the user equipment reports important CA combinations to the access network device as much as possible.

In the method for reporting carrier aggregation combinations provided in this embodiment, when the user equipment reports multiple CA capabilities, the identities of multiple first CA combinations related to various CA capabilities are sorted according to the priorities of multiple first CA combinations. , which can ensure that the user equipment reports important CA combinations to the access network equipment as much as possible with limited transmission capacity.

Optionally, the capability query request is specifically used to query multiple CA capabilities of the user equipment; the above step S202 can be implemented in the following manner:

sending a plurality of device capability information respectively corresponding to multiple CA capabilities to the access network device according to the capability query request;

Wherein, each device capability information includes identifiers of multiple first CA combinations related to corresponding CA capabilities, and the identifiers of multiple first CA combinations included in each device capability information are sorted according to priority.

In this embodiment, the capability query request is specifically used to query multiple CA capabilities of the user equipment. It should be noted that when the access network device queries multiple CA capabilities of the user equipment, the user equipment may send multiple CA capabilities to the access network device, and send device capability information corresponding to one CA capability each time.

For example, when the capability query request is specifically used to query the 4G-5G CA capability and the 5G CA capability of the user equipment, the user equipment sends the CA capability to the access network device twice, and sends the device capability information corresponding to a CA capability each time . For example, the user equipment first sends the device capability information corresponding to the 4G-5G CA capability to the access network device, and then sends the device capability information corresponding to the 5G CA capability.

According to the reporting method of carrier aggregation combination provided in this embodiment, the user equipment can send the CA capability to the access network device multiple times, and send the device capability information corresponding to a CA capability each time. Since the device capability information corresponding to the CA capability is sent each time The maximum sending capacity of the CA is 8K bytes, so as many device capability information corresponding to each CA capability as possible can be sent to the access network device. Moreover, since the identifiers of multiple first CA combinations included in each device capability information are sorted according to priority, it can be ensured that the user equipment can report important CA combinations to the access network device as much as possible with limited transmission capacity.

Optionally, if there are multiple first CA combinations of the same priority, the identifiers of the multiple first CA combinations of the same priority are sorted according to the query order, and the query sequence is the same as the sort of the identification of the frequency band carried in the capability query request unanimous.

If the 4G bands inquired by the access network device are B1, B3, B7, and B8 in sequence, and the 5G bands inquired are N1 and N3 in sequence, the first CA combination with the same priority includes B1-B3-B7-B8-N1, B1-B3-B7-B8-N3, B7-B8-N3, B3-B7-B8-N1, B8-N3, since the 4G bands inquired by the access network equipment are B1, B3, B7, B8 in turn, the same The identifiers of the first priority CA combination are B1-B3-B7-B8-N1, B1-B3-B7-B8-N3, B3-B7-B8-N1, B7-B8-N3, B8-N3 logo.

In this embodiment, when there are multiple first CA combinations with the same priority, the identifiers of the multiple first CA combinations with the same priority are sorted according to the query order, so that the user equipment can query according to the access network equipment. Inquiry order of the frequency band, using the limited transmission capacity to report important CA combinations to the access network equipment as much as possible.

Optionally, as shown in FIG. 3 , FIG. 3 is a schematic flowchart of a method for acquiring a first CA combination provided in an embodiment of the present application. This embodiment relates to an optional implementation manner of how to obtain the first CA combination. The steps involved in this embodiment are before step S202. On the basis of the foregoing embodiments, the method also includes the following steps:

S301. Determine a plurality of second CA combinations according to the identification of the frequency band, where the second CA combination includes carriers in the frequency band, and the second CA combination is a CA combination supported by the operator's network and the user equipment.

Wherein, if the frequency band carried in the capability query request includes only 5G bands, the determined multiple second CA combinations may include CA combinations related to 5G CA capabilities among the CA combinations supported by the operator network and the user equipment. If the frequency band carried in the capability query request includes 4G bands and 5G bands, the determined multiple second CA combinations may include CAs related to the 4G-5G CA capabilities in the CA combinations supported by the operator network and the user equipment. Combinations and CA combinations related to 5G CA capabilities.

S302. Acquire a first CA combination from multiple second CA combinations in order of priority according to the first transmission capacity limitation threshold, wherein the acquired first CA combination identifies a data volume that is less than or equal to the first transmission capacity limitation threshold .

In this embodiment, the identification of the first CA combination is obtained from multiple second CA combinations in order of priority, which means that the second CA combination with high priority is obtained first, and the second CA combination with high priority is used as the first CA combination. CA combination.

The method for reporting the carrier aggregation capability provided in this embodiment determines multiple second CA combinations according to the identification of the frequency band, and obtains the first CA combination from the multiple second CA combinations according to the order of priority, so as to realize the acquired first CA combination. The combination is an important CA combination, so as to effectively use the limited capacity to report the important CA combination to the access network device, and the reported CA combination is the CA combination supported by the access network device.

Optionally, step S301 may be implemented in the following manner:

According to the identification of the frequency band, the second CA combinations corresponding to multiple CA capabilities are respectively determined.

For example, if the capability query request is specifically used to query the 4G-5G CA capability and 5G CA capability of the user equipment, then according to the identification of the frequency band, determine the second CA combination corresponding to the 4G-5G CA capability and the 5G CA capability corresponding The second CA combination.

Correspondingly, in step S302, obtaining the first CA combination from the plurality of second CA combinations according to the order of priority may be implemented in the following manner:

For each CA capability, the first CA combination is obtained from multiple second CA combinations corresponding to the CA capability in order of priority, wherein the data volume of the obtained identifier of the first CA combination is less than or equal to the first CA combination corresponding to the CA capability. Send capacity limit threshold.

In this embodiment, the order of priority refers to the order of priority of each second CA combination in the multiple second CA combinations corresponding to the CA capability from high to low, and is obtained from multiple second CA combinations corresponding to the CA capabilities. First CA combination.

The sum of the first transmission capacity limitation thresholds corresponding to the respective CA capabilities is not greater than the maximum transmission capacity limitation threshold of the user equipment. For example, the sum of the first transmission capacity limit threshold corresponding to the 4G-5G CA capability and the first transmission capacity limit threshold corresponding to the 5G CA capability cannot be greater than 8K bytes.

In this embodiment, if the user equipment reports the 4G-5G CA capability and the 5G CA capability to the access network device. For the 4G-5G CA capability, if the 4G-5G CA capability corresponds to 300 second CA combinations, the 5G CA capability corresponds to 250 second CA combinations. Among the 300 second CA combinations, there are 50 second CA combinations with priority P0, 50 second CA combinations with priority P1, 100 second CA combinations with priority P2, and priority P3 The second CA combination has 100. Among them, P0 has the highest priority, P1 has a lower priority than P0, P2 has a lower priority than P1, and P3 has a lower priority than P2.

Due to the limitation of the capacity of the CA combination reported by the user equipment to the access network device, the user equipment can only send 124 second CA combinations to the access network device at most, then according to the priority order of the 300 second CA combinations, from the highest The first 124 second CA combinations with the highest priority are selected from the lowest. The 124 second CA combinations include 50 second CA combinations with priority P0, 50 second CA combinations with priority P1, and P2 priority 24 second CA combinations, and use the 124 second CA combinations as the 4G-5G CA capability corresponding to the first CA combination.

Similarly, for the 5G CA capability, if the 5G CA capability corresponds to 250 second CA combinations, according to the above-mentioned method for obtaining the first CA combination corresponding to the 4G-5G CA capability, from the 250 second CA combinations Obtaining the CA capability of 5G corresponds to the first CA combination. For example, if the first sending capacity limit threshold is 8K bytes, and the 124 identifiers of the first CA combination corresponding to the 4G-5G CA capability occupy 4.3K bytes, the remaining 3.7K bytes can be used to report the 5G CA The capability corresponds to the identity of the first CA combination. If the remaining 3.7K bytes can be used to report the identifiers of the first CA combinations corresponding to the 110 5G CA capabilities, select 110 second CA combinations with high priority from the 250 second CA combinations as the 5G CA Capabilities correspond to the first CA combination.

In this embodiment, when the capability query request is specifically used to query multiple CA capabilities of the user equipment, for each CA capability, the first CA is obtained from multiple second CA combinations corresponding to the CA capabilities in order of priority. combination, and the data volume of the identification of the first CA combination corresponding to various CA capabilities is less than or equal to the first transmission capacity limit threshold, so as to realize the effective use of limited capacity to report important CA combinations to the access network device.

Optionally, according to the identification of the frequency band, respectively determining the second CA combination corresponding to multiple CA capabilities may be implemented in the following manner:

For each CA capability, the CA combination table corresponding to the CA capability preset in the user equipment is queried according to the identification of the frequency band to obtain a plurality of second CA combinations corresponding to the CA capability, wherein the CA combination table stores operator CA combinations supported by both the network and the user equipment.

In this embodiment, a CA combination table corresponding to the CA capability may be preset in the user equipment, and the user equipment may obtain multiple second CA combinations corresponding to the CA capability by querying the CA combination table. For example, the CA combination table corresponding to the 4G-5G CA capability and the CA combination table corresponding to the 5G CA capability are preset in the user equipment.

Table 1

The user equipment may obtain multiple second CA combinations corresponding to CA capabilities by querying, for example, the combination table 1 above. According to the priority of each CA combination in the combination table 1, the user equipment may preferentially inquire about a high-priority CA combination as multiple second CA combinations corresponding to the CA capability.

Optionally, the CA capability includes Evolved Universal Terrestrial Radio Access New Air Interface Dual Connectivity EN-DC capability and New Air Interface Carrier Aggregation NR-CA capability; or, the CA capability includes New Air Interface Evolved Universal Terrestrial Radio Access Dual Connectivity NE-DC capability And new air interface carrier aggregation NR-CA capability.

It should be noted that, under Non Standalone (NSA), user equipment can simultaneously use 4G base stations and 4G base stations, with 4G base stations serving as primary base stations and 5G base stations serving as secondary base stations. When the user equipment is in 4G mode, it can report the EN-DC capability and New Radio Carrier Aggregation (NR-CA) capability to the 4G base station.

In NR Standalone (SA), user equipment can use 5G base stations and 4G base stations at the same time. The 5G base station is used as the primary base station, and the 4G base station is used as the secondary base station. The base station reports the Evolved Universal Terrestrial Radio Access New Air Interface Dual Connection (NR-EUTRA Dual Connection, NE-DC) capability and New Radio Carrier Aggregation (New Radio Carrier Aggregation, NR-CA) capability.

It should be noted that EN-DC is the CA capability of 4G-5G, and NE-DC is the CA capability of 5G-4G.

Optionally, obtaining the first CA combination from multiple second CA combinations according to the order of priority may be implemented in the following manner:

If there are multiple second CA combinations of the same priority, the first CA combination is obtained from the second CA combinations of the same priority according to the query sequence, wherein the query sequence is the same as the identity of the frequency band included in the capability query request Sort consistent.

For example, in the above example, 50 second CA combinations with a priority of P0, 50 second CA combinations with a priority of P1, and 50 second CA combinations with a priority of P2 are selected from the 300 second CA combinations corresponding to 4G-5G CA capabilities 24 second CA combinations, and use the 124 second CA combinations as the 4G-5G CA capability corresponding to the first CA combination.

Among them, there are 100 second CA combinations with a priority of P2, and 24 second CA combinations are selected from the 100 second CA combinations according to the query sequence of the frequency band carried in the capability query request. For example, the 100 second CA combinations include CA combinations starting from B3 and CA combinations starting from B7. And the CA combinations starting from B3 include B3-B7-B8-N1-N3, B3-B8-N1-N3, etc. a total of 25 CA combinations, and the CA combinations starting from B7 include B7-B8-N3, B7-N3, B7-B8 -75 CA combinations such as N1-N3, according to the query order, obtain the first CA combination from the second CA combination of the same priority, that is to say, because B3 is located before B7 in the query sequence, therefore, this embodiment 24 CA combinations are selected from the 25 CA combinations starting from B3, and 24 CA combinations are not selected from the 75 CA combinations starting from B7.

In this embodiment, when there are multiple second CA combinations of the same priority, the first CA combination is obtained from the second CA combinations of the same priority according to the query order, so as to realize the effective use of limited capacity Report important CA combinations to access network devices.

Optionally, on the basis of the foregoing embodiments, the following steps may also be included:

If the user equipment fails to access the network after sending the device capability information, the device capability information of the user equipment is sent next based on the second sending capacity limit threshold, which is smaller than the first send capacity limit threshold.

It should be noted that if the user equipment fails to access the network after sending the device capability information, the first sending capacity limit threshold may be reduced, for example, the first sending capacity limit threshold may be reduced to half of the original value. For example, if the first sending capacity limitation threshold is 8K bytes, the reduced first sending capacity limitation threshold is 4K bytes. In this embodiment, the second sending capacity limit threshold is equal to the reduced first sending capacity limit threshold.

This embodiment is applicable in some individual environments, where the receiving and reporting capability of the network does not reach the upper limit of the 3rd Generation Partnership Project (3rd Generation Partnership Project, 3GPP) specification. The upper limit of the 3GPP specification is, for example, 8K bytes, causing users to The device failed to report device capability information. In this case, the user equipment may lower the first sending capacity limitation threshold, and transmit the device capability information of the user equipment next based on the second sending capacity limitation threshold. That is to say, there is also a maximum upper limit on the capacity of the access network device that can correctly receive and process the CA capability reported by the user equipment. Once the limit is exceeded, various exceptions will occur. In the slightest, the registration is rejected, the wireless resource connection is released by the network, etc., and in the worst case, random access is affected, resulting in the failure of various subsequent services, such as Short Message Service (Short Message Service, SMS) reception, telephone calls, data, etc. Through comparative tests, it can be clarified that the root cause of this is the failure of the user equipment to report equipment capability information due to the limitation of the receiving capacity of the access network equipment. Therefore, when the user equipment fails to report the equipment capability information, the user equipment can reduce the first transmission The capacity limit threshold is to transmit the equipment capability information of the user equipment next based on the second sending capacity limit threshold, so as to be compatible with the network.

For example, because the access network equipment has not been fully upgraded, the upper limit of the 3GPP specification supported by the access network equipment is less than the maximum reported capacity threshold of the user equipment, so the capacity supported by the access network equipment cannot reach 8K bytes. In some access network devices in Germany, Poland, and after the user equipment reported the equipment capability information, the access network equipment was abnormal because it could not reach 8K bytes, and the user equipment could no longer receive the called paging from the network. In this case, the device capability information of the user equipment may be sent next time based on the second sending capacity limit threshold.

Although this application is based on the official network deployment information of the operator's network, the user equipment has prepared a corresponding reporting combination, that is, the user equipment reports the operator's network to which the identity card belongs and the CA combination supported by the user equipment. However, since the receiving and reporting capability of the access network equipment is less than the maximum reporting capacity threshold supported by the mobile phone, the user equipment cannot receive the called page from the network after reporting the equipment capability information. In order to avoid various abnormalities caused by the limitation of the receiving and reporting capabilities of the access network equipment, such as abnormal phone calls, abnormal SMS messages, and unstable data networks, etc., after sending the equipment capability information in this embodiment, if the user equipment fails to access the network , the device capability information of the user equipment is sent next time based on the second sending capacity limit threshold, so that the user equipment is compatible and adaptable to the network in a timely manner.

It should be noted that the above-mentioned failure of the user equipment to report the equipment capability information includes: after the user equipment sends the equipment capability information to the access network equipment, although the access network equipment receives the equipment capability information of the user equipment, the access network equipment cannot Processing the device capability information of the user equipment means that the user equipment fails to report the device capability information.

When the access network equipment cannot normally process the equipment capability information of the user equipment, if the access network equipment no longer normally responds to the mobile phone signaling and registration process, but actively gives negative feedback to the user equipment, it can be determined that negative network feedback has occurred exception. Occurrence of network negative feedback includes negative feedback sent to the user equipment when the access network equipment cannot normally process the equipment capability information of the user equipment.

The above-mentioned first sending capacity limit threshold corresponding to each CA capability may be determined through an actual network environment measurement. Because in some individual environments, the access network equipment has various abnormalities when the EN-DC capability reported by the user equipment or the NR CA capability exceeds 4K bytes. Therefore, the first transmission capacity limitation threshold corresponding to the EN-DC capability and the first transmission capacity limitation threshold corresponding to the NR CA capability can be determined by testing the access network equipment.

For example, currently when testing a certain access network device, the data volume of the device capability information corresponding to the NR CA capability reported by the user equipment to the access network device is generally small, for example, about 2K bytes, and the NR CA capability corresponding to Set the first sending capacity limit threshold to 2K bytes, and fix the threshold, change the sending capacity limit threshold corresponding to the EN-DC capability to test the bottleneck value corresponding to the EN-DC capability, and use this bottleneck value as the EN-DC capability The corresponding first sending capacity limit threshold. For example, if the sending capacity limit threshold corresponding to the EN-DC capability is 6K bytes, 5.5K bytes, or 5K bytes, the user equipment fails to report the device capability information, but when the sending capacity limit threshold is adjusted to 4K bytes, If the user equipment successfully reports the equipment capability information to the access network device, the bottleneck value corresponding to the EN-DC capability is 4K bytes, and 4K bytes can be used as the first transmission capacity limit threshold corresponding to the EN-DC capability.

Optionally, the above-mentioned sending of the device capability information of the user equipment next time based on the second sending capacity limit threshold may be implemented in the following manner:

If the second sending capacity limit threshold is greater than or equal to the minimum sending capacity limit threshold, the device capability information of the user equipment is sent next time based on the second sending capacity limit threshold.

In this embodiment of the present application, if the user equipment receives the capability query request sent by the access network device, the data volume of the identification of the first CA combination included in the device capability information reported to the access network device for the first time is equal to that of the first sent capacity limit threshold, and the user equipment fails to connect to the network after sending the device capability information, the user equipment can first determine whether the second transmission capacity limit threshold is greater than or equal to the minimum transmission capacity limit threshold, if the second transmission capacity limit threshold is greater than or equal to the minimum If the sending capacity limit threshold is used, the device capability information of the user equipment is sent next time based on the second sending capacity limit threshold.

In the method for reporting carrier aggregation combinations provided in this embodiment, when the second transmission capacity limitation threshold is greater than or equal to the minimum transmission capacity limitation threshold, the next transmission of the user equipment capability information based on the second transmission capacity limitation threshold can avoid user equipment After the device fails to join the network, it continues to report device capability information to the network by lowering the limit threshold of the sending capacity.

It should be noted that, when the second sending capacity limit threshold is smaller than the minimum sending capacity limit threshold, it is forbidden to send the equipment capability information of the user equipment based on the second sending capacity limit threshold next time.

This embodiment realizes reducing the data amount of the first CA combination identifier reported by reducing the sending capacity limit threshold. If the reduced sending capacity limit threshold is smaller than the minimum sending capacity limit threshold, that is, the second sending capacity limit threshold is smaller than the minimum sending capacity limit the threshold, the user equipment does not need to send the device capability information of the user equipment next time based on the second sending capacity limit threshold. In a case where the second sending capacity limitation threshold is smaller than the minimum sending capacity limitation threshold, the user equipment may determine that an abnormality has occurred in the network.

Optionally, the failure of the user equipment to access the network includes the failure of the network registration of the user equipment. If the user equipment fails to access the network after sending the equipment capability information, the next transmission of the equipment capability information of the user equipment based on the second sending capacity limit threshold may be implemented in the following manner :

If the user equipment receives a message indicating network registration failure, then send the device capability information of the user equipment next time based on the second sending capacity limit threshold;

Wherein, the message used to indicate network registration failure includes any one of an attach reject message, a tracking area update reject message, a detach message, a radio resource control connection release message, a registration reject message, and a deregistration request message.

When the user equipment is in LTE mode, if the user equipment receives negative feedback, that is, the user equipment receives a message indicating that the network registration fails, the device capability information of the user equipment is sent next time based on the second transmission capacity limitation threshold.

When the user equipment is in LTE mode, the message used to indicate network registration failure includes any of the following messages:

A: The user equipment receives the Attach reject message sent by the access network device;

B: The user equipment receives the TAU reject (tracking area update rejection) message sent by the access network device;

C: The user equipment receives a Detach (detach) message sent by the access network device;

D: The user equipment receives the RRC Connection Release (radio resource control connection release) message sent by the access network device.

When the user equipment is in NR SA mode, the message used to indicate network registration failure includes any of the following messages:

A: The user equipment receives the REGISTRATION REJECT message sent by the access network device;

B: The user equipment receives the RRC Connection Release (radio resource control connection release) message sent by the access network device;

C: The user equipment receives a DEREGISTRATION REQUEST (deregistration request) message sent by the access network device.

It should be noted that, when the number of consecutive receptions of messages indicating network registration failure exceeds a certain number of times, the user equipment may send the device capability information of the user equipment next based on the second sending capacity limitation threshold. For example, the certain number of times is, for example, 2 times.

Optionally, sending the device capability information of the user equipment next time based on the second sending capacity limit threshold may be implemented in the following manner:

For each CA capability, the device capability information of the user equipment is sent next time based on the second transmission capacity limit threshold corresponding to the CA capability.

In this embodiment, when the user equipment reports equipment capability information corresponding to multiple CA capabilities to the access network device, for each CA capability, the next transmission of the user equipment's device information may be based on the second transmission capacity limit threshold corresponding to the CA capability. capability information. For example, based on the second transmission capacity limit threshold corresponding to the 4G-5G CA capability, the device capability information of the user equipment is sent next time, and based on the second transmission capacity limit threshold corresponding to the 5G CA capability, the device capability information of the user equipment is sent next time .

Optionally, the failure of the user equipment to access the network includes the random access failure of the user equipment, and the method also includes:

After sending the device capability information, if the random access of the user equipment fails, re-initiate the network registration process, and receive the next capability query request sent by the access network device after re-initiating the network registration process, and based on the second transmission capacity The limit threshold sends the device capability information corresponding to the next capability query request to the access network device.

In this embodiment, after the device capability information is sent, if the random access of the user equipment fails, the user equipment can actively and intelligently enter and exit the flight mode, and then re-initiate the network registration process to retry the registration.

After re-initiating the network registration process, the user equipment receives the next capability query request sent by the access network device after re-initiating the network registration process, and sends the next capability query request to the access network device based on the second sending capacity limit threshold Corresponding device capability information.

The second sending capacity limit threshold corresponding to various CA capabilities may be half of the corresponding first sending capacity limit threshold. For example, if the first sending capacity limit threshold corresponding to the EN-DC capability is 4K, and the first sending capacity limit threshold corresponding to the NR-CA capability is 4K bytes, then the first sending capacity limit threshold corresponding to the EN-DC capability can be set to At least one of the first transmission capacity restriction thresholds corresponding to the NR-CA capability is reduced to 2K.

It should be noted that the first sending capacity limit threshold may also be a system default value, and when the first sending capacity limit threshold is the system default value, the system default value may be reduced to one-half of the system default value.

In this embodiment, after sending the device capability information, if the random access of the user equipment fails, the network registration process is re-initiated, and the next capability query request sent by the access network device after re-initiating the network registration process is received, and based on The second sending capacity limit threshold sends the device capability information corresponding to the next capability query request to the access network device, so as to be compatible with the network.

Optionally, if the random access of the user equipment fails, re-initiate the network registration process, including:

If the number of consecutive random access failures of the user equipment exceeds the number threshold, the network registration process is re-initiated.

For example, the number of times threshold is 5 times, and if the number of consecutive random access failures of the user equipment exceeds 5 times, the network registration process is re-initiated.

Optionally, if the random access of the user equipment fails, the network registration process is re-initiated, which can be achieved in the following ways:

If the signal strength of the access network device received by the user equipment is greater than the signal strength threshold and the signal-to-noise ratio of the signal is less than the signal-to-noise ratio threshold, and the number of consecutive random access failures of the user equipment exceeds the threshold, the network registration process is reinitiated .

If the signal strength of the access network device received by the user equipment is greater than the signal strength threshold and the signal-to-noise ratio of the signal is less than the signal-to-noise ratio threshold, it means that the signal of the access network device received by the user equipment is a strong signal without interference, Under such network conditions, if the number of consecutive random access failures of the user equipment exceeds the number threshold, the user equipment can determine that the network is abnormal, and then can actively enter and exit the flight mode and try network registration again.
