First embodiment
Referring to fig. 2, fig. 2 is a flowchart illustrating a method for updating carrier aggregation capability according to a preferred embodiment of the present invention. The method is applied to the user terminal 100. The specific procedure of the carrier aggregation capability updating method is described in detail below.
Step S110, generating a carrier aggregation capability pool of the user terminal 100 according to the configuration file of the SIM card of the user terminal 100.
Referring to fig. 3, fig. 3 is a schematic flow chart illustrating sub-steps of step S110 in fig. 2 according to a preferred embodiment of the present invention, where the step S110 may include sub-step S111, sub-step S112, sub-step S113, and sub-step S114.
And a substep S111, detecting the type of the SIM card.
In this embodiment, the type of the SIM card may be, but is not limited to, different types of SIM cards provided by different operators (e.g., unicom, mobile, telecommunication, etc.).
And a substep S112, activating a configuration file corresponding to the SIM card according to the detected type of the SIM card.
In this embodiment, the user terminal 100 activates the configuration file corresponding to the SIM card based on the detected operator type of the SIM card, and obtains information included in the corresponding configuration file. In this embodiment, the configuration file is stored in the memory 110 of the user terminal 100. The configuration file includes: roaming rule information of an operator, local network frequency band combination information, carrier aggregation combination initial information and the like.
Substep S113 detects all network bands supportable by the ue 100.
In this embodiment, the ue 100 detects all network band combination information that the hardware condition of the ue 100 can support.
And a substep S114, generating a carrier aggregation capability pool of the user terminal 100 according to the configuration file and all network frequency bands supportable by the user terminal 100.
In this embodiment, the ue 100 generates a carrier aggregation capability pool based on the information obtained from the configuration file and all network frequency band information that can be supported by the ue 100 hardware. Wherein, the carrier aggregation capability pool refers to a carrier aggregation combination list which can be maintained and supported by the user terminal 100 in a local network. The carrier aggregation combination list information is stored in the memory 110 of the user terminal 100.
Step S140, detecting the serving cell information and the neighboring cell information of the network where the user terminal 100 is currently located, so as to obtain the network frequency band coverage information of the user terminal 100.
In this embodiment, the serving cell information refers to network frequency band information included in a local network cell currently used by the ue 100, and the neighboring cell information refers to network frequency band information included in a neighboring cell not currently used by the ue 100. The network frequency band coverage information includes network frequency band coverage information of a serving cell where the user terminal 100 is located and network frequency band coverage information of an adjacent cell.
Step S150, updating the carrier aggregation capability pool of the user terminal 100 according to the obtained network frequency band coverage information.
In this embodiment, the user terminal 100 adjusts the carrier aggregation combination corresponding to the network coverage frequency band based on the acquired network frequency band coverage information, so that the carrier aggregation combination corresponding to the network coverage frequency band is within the preset reporting information range of the carrier aggregation capability pool, thereby ensuring that the carrier aggregation combination corresponding to the network coverage frequency band is preferentially reported. The preset reporting information range refers to a maximum number of carrier aggregation combinations reported by the user terminal 100, which are limited by parameter standards (e.g., maxBandComb-r10, maxBandComb-r11, maxBandComb-r10+ maxBandComb-r11, etc.) specified by 3GPP (3rd Generation partnership project, third Generation partnership project) protocol.
Referring to fig. 4, fig. 4 is a flowchart illustrating another step of a carrier aggregation capability updating method according to a preferred embodiment of the invention. The method comprises the following steps in addition to the steps:
step S160, receiving a carrier aggregation capability query instruction sent by the base station, and reporting the updated carrier aggregation capability pool information to the base station.
In this embodiment, after the ue 100 successfully establishes an RRC (Radio Resource Control) connection, the ue 100 may report capability information (ue capability information) of the ue 100 at an initial time by itself or according to a carrier aggregation capability query (uecapabilityinquiry) issued by a base station (eNodeB, Evolved Node B, i.e., name of the base station in LTE). The ue 100 fills the UECapabilityInformation according to the priority order of the non-carrier aggregation combination information, the 2DL +1UL CA combination of all frequency bands, and the other carrier aggregation combinations of all frequency bands, and reports the information to the base station according to the existing 3GPP protocol.
In this embodiment, RRC refers to radio resource control, and handles the third layer information of the control plane between the user terminal 100 and the base station. CA (Carrier Aggregation) is a technology that aggregates a plurality of continuous or discrete Carrier units (CCs) together to form a wider spectrum, and the application of this technology not only meets the requirement of LTE-Advanced in terms of bandwidth, but also can improve the utilization rate of spectrum fragments. The carrier unit includes an uplink (Up Link) CC and a downlink (Down Link) CC. The 2DL +1ULCA combination refers to a currently common carrier aggregation combination form of two downlink carrier units + one uplink carrier unit.
In this embodiment, the information rule included in the capability information (UECapabilityInformation) of the user terminal 100 is as follows:
a. including all non-carrier aggregation frequency band information supported by the user terminal 100.
b. If the ue capability inquiry message sent by the base station includes required frequency band field information (requested frequency bands), and the user terminal 100 supports the report of the required frequency band field information, then:
including all 2DL +1UL CA combinations of the frequency bands listed in the required band field information;
including all other CA combinations that require a frequency band listed in the band field information, for example: CA combinations such as 3DL, 4DL, 5DL and 2 UL.
c. If the ue capability entity message sent by the base station does not include the required frequency band field information (requested frequency bands), or the user terminal 100 does not support the report of the required frequency band field information, then:
a 2DL +1UL CA combination including all frequency bands supported by the user terminal 100;
other CA combinations including all frequency bands supported by the user terminal 100, for example: CA combinations such as 3DL, 4DL, 5DL and 2 UL.
Referring to fig. 4 again, before the step S140, the method further includes:
step S120, performing local network registration on the user terminal 100 based on the configuration file corresponding to the SIM card and all network bands that can be supported by the user terminal 100.
In this embodiment, the user terminal 100 starts a network searching process, and performs local network registration on the user terminal 100 based on the configuration file corresponding to the SIM card and all network frequency bands that can be supported by the user terminal 100. If the registration is successful, step S130 is executed, and if the registration is unsuccessful, the registration operation is repeated until the registration is successful.
Step S130, determining a current roaming state of the SIM card based on the configuration file corresponding to the SIM card.
In this embodiment, the user terminal 100 determines whether the SIM card is currently in a roaming state based on the roaming rule of the operator included in the configuration file. The roaming rule of the operator is determined by comparing the PLMN of the home network currently registered by the user terminal 100 with the HPLMN in the SIM card; if the information of the registered home network PLMN is inconsistent with the information of the HPLMN in the SIM card, it indicates that the user terminal 100 is in a roaming state. In this embodiment, roaming (roaming) refers to a function that the user terminal 100 leaves a service area where the SIM card is registered, and after moving to another service area, the mobile communication system can still provide service to the user terminal, that is, the user terminal 100 moves to another service area using the SIM card of one operator to register with a network of another operator.
In the present embodiment, a PLMN (Public Land Mobile Network) is a Network established and operated by an operator approved by the government or government for the purpose of providing a Land Mobile communication service to the Public. The PLMN includes MCC and MNC, and the resources of MCC (Mobile Country Code) are uniformly distributed and managed by International Telecommunications Union (ITU), which uniquely identifies the Country to which the user terminal 100 belongs, and 3 digits in total, where china is 460. In the same country, if there are multiple PLMNs (generally, one PLMN corresponds to one operator in a certain country), the difference is made by using a Mobile Network Code (MNC), that is, each PLMN is assigned a unique MNC. The MNC is used to identify the mobile communication network to which the user terminal 100 belongs, and is composed of 2-3 digits. For example, china mobile systems use 00, 02, 04, 07, china unicom GSM systems use 01, 06, 09, china telecom CDMA systems use 03, 05, and china railway system use 20. The HPLMN (Home PLMN ) is a PLMN to which the SIM card of the user terminal 100 belongs, that is, MCC and MNC contained in the HPLMN of the SIM card of the user terminal 100 are identical to MCC and MNC contained in the operator network PLMN to which the SIM card belongs, and for a certain SIM card of the user terminal 100, there is only one PLMN to which the PLMN belongs.
In this embodiment, when the SIM card is in the roaming state, step S135 is executed.
In step S135, the frequency band range supported by the local network is detected based on the configuration file corresponding to the SIM card, and the carrier aggregation capability pool of the user terminal 100 is reconfigured.
In this embodiment, the user terminal 100 redetects the frequency range supported by the network where the user terminal 100 is currently located according to the network where the SIM card is currently located and the local network frequency range combination information included in the configuration file. And adjusting the detected carrier aggregation combination corresponding to the frequency range supported by the current network to be within the preset reporting information range of the carrier aggregation capability pool. So that the detected carrier aggregation combination corresponding to the frequency range supported by the current network can be preferentially reported to the base station.
In this embodiment, the local network frequency band combination information included in the configuration file refers to the network frequency band combination information supported by the operator network to which the SIM card belongs.
When the SIM card is not in the roaming state, the user terminal 100 performs step S140.
