Description

Method for coordinating communication resources and related product

The present application is a divisional application, the original application having application number 201910766372.8, the original application having application date of 2019, 08 and 16, the entire content of the original application being incorporated by reference in the present application.

Technical Field

The present application relates to the field of communications technologies, and in particular, to a method for coordinating communication resources and a related product.

Background

With the development of wireless communication Technology, the types of Radio Access Technology (RAT) in commercial use are various, and due to different RAT types, an operator sells different Subscriber Identity Module (SIM) cards at different times, different SIM support different RAT types, and due to different RAT types, different communication resources are used by different SIMs to communicate with the network side. Therefore, a plurality of (two) different SIMs can be installed on the UE to meet different communication requirements of the user, but for the existing dual-SIM UE, the UE can only use one SIM for communication at the same time, which results in SIM resource waste.

In addition, when the UE capability changes, the UE needs to report the UE capability to the network side again, and the UE needs to request the network side to initialize a non-access stratum (NAS) and reconfigure a transmission link parameter of the UE, which causes communication interruption of the UE. For a UE with dual SIMs, when the UE is switched from SIM1 to SIM2, for example, the RAT types supported by SIM1 and SIM2 are different, which results in different UE capabilities used by SIM1 and SIM2, when the UE is switched to SIM2, the UE needs to report the UE capability that can be used by SIM2 to the base station again, execute an update process of the UE capability, request the network side to initialize an NAS procedure, reconfigure a transmission link parameter of the UE, interrupt a communication process of the UE, and affect user experience.

Therefore, the resource utilization rate of the multi-SIM UE to the SIM is low, and when the working state of the SIM is switched, the communication process of the UE is interrupted, which affects the user experience.

Disclosure of Invention

The application provides a communication resource coordination method and a related product, which can dynamically coordinate communication resources of UE (user equipment) when the working state of an SIM (subscriber identity module) changes, complete the switching of the working state of the SIM, and can not interrupt the communication process of the UE, thereby improving the user experience.

In a first aspect, a method for coordinating communication resources is provided, where the method is applied to a user equipment UE including a first subscriber identity module SIM and a second SIM, and includes:

when the working state of the first SIM and/or the working state of the second SIM are/is changed and the current working state of at least one SIM in the first SIM and the second SIM is a connected state, the UE sends a request message to access network equipment according to the current working state of the first SIM and the current working state of the second SIM, wherein the request message is used for requesting the access network equipment to coordinate communication resources of the UE;

and the UE receives response information of the access network equipment responding to the request message, wherein the response information carries a first coordination result of the communication resources of the UE.

In this example, when the working states of the first SIM and/or the second SIM are changed and the current working state of one SIM is a connected state, the UE sends a request message to the access network device, and the access network device coordinates communication resources of the UE to maintain the normal working states of the two SIMs, so that the utilization rate of the SIM resources is improved; moreover, when the working state of the SIM changes, the access network device coordinates the communication resources of the UE without executing the UE capability update procedure, without participation of the core network device, without executing the initialization NSA procedure, without interrupting the communication process of the UE, thereby improving the user experience.

With reference to the first aspect, in a possible implementation manner of the first aspect, when the first SIM is always in the connected state and the second SIM is changed from the first idle state to the connected state, the UE originally uses only the first SIM for communication, so that the first SIM occupies all communication resources of the UE, and when the second SIM is changed from the first idle state to the connected state, the first SIM competes for communication resources of the UE with the first SIM. At this time, in order to use two SIMs for communication simultaneously, the UE reports the capability information of the two SIMs to the access network device through the first SIM, requests the access network device to coordinate the communication resources of the UE according to the capability information of each SIM, and allocates corresponding communication resources to each SIM, so that each SIM uses the communication resources allocated to itself for communication.

With reference to the first aspect, in a possible implementation manner of the first aspect, when the first SIM is always in the connected state and the second SIM is changed from the second idle state to the connected state, the UE originally uses only the second SIM to monitor the paging message, so that the second SIM only occupies a downlink communication resource for supporting paging in the downlink communication resource of the UE, and when the second SIM is changed from the second idle state to the connected state, the communication resource required by the second SIM changes and needs to compete with the first SIM for the communication resource of the UE. At this time, in order to use two SIMs for communication at the same time, the UE reports the capability information of the two SIMs to the access network device, requests the access network device to coordinate the communication resources of the UE according to the capability information of each SIM, and allocates corresponding communication resources to each SIM, so that each SIM uses the communication resources allocated to it for communication.

With reference to the first aspect, in a possible implementation manner of the first aspect, when the first SIM is always in the connected state and the second SIM is also in the connected state, the communication resources of the UE are originally occupied by the two SIMs, and when the second SIM is changed from the connected state to the first idle state, the access network device may release all the communication resources occupied by the second SIM, and the part of the communication resources may be in the idle state. At this time, in order to reasonably utilize the communication resources of the UE, the UE may send the capability information of the first SIM to the access network device, request the access network device to coordinate the communication resources of the UE, and allocate more communication resources to the first SIM to support the communication of the first SIM.

With reference to the first aspect, in a possible implementation manner of the first aspect, when the first SIM is always in a connected state and the second SIM is also in a connected state, the communication resource of the UE is originally occupied by the two SIMs, and when the second SIM is changed from the connected state to the second idle state, the access network device releases the communication resource occupied by the second SIM, and in addition, the UE needs to use the second SIM to monitor the paging message. At this time, in order to maintain the first SIM operating in the connected state and the second SIM operating in the second idle state, the UE sends the capability information of the first SIM and the second capability information of the second SIM to the access network device, requests the access network device to coordinate the communication resources of the UE, and allocates corresponding communication resources to each SIM, so that each SIM uses the communication resources allocated to it to perform communication.

With reference to the first aspect, in a possible implementation manner of the first aspect, when a radio resource control RRC state of any one of the first SIM and the second SIM is in an idle state, and the UE does not receive a paging message of the SIM, an operating state of the SIM is in a first idle state, that is, in a completely idle state, and at this time, the UE uses another SIM for communication, where the RRC state of the SIM is used to characterize whether the UE establishes an RRC connection with the access network device through the SIM;

when the RRC state of the SIM is an idle state and the UE receives the paging message of the SIM, the working state of the SIM is a second idle state, that is, the UE can use the SIM to receive the corresponding paging message, and at this time, another SIM can be in any working state;

when the RRC state of the SIM is a connected state, the operating state of the SIM is the connected state, that is, the UE uses the SIM to perform communication, at this time, another SIM may be in any operating state, if another SIM is also in a connected state, the UE may simultaneously use two SIMs to perform communication, and if another SIM is in a second idle state, the UE may use a paging message for monitoring another SIM while performing communication using the SIM.

In this example, the working state of each SIM is not affected by the working state of another SIM, and may be in a completely idle state, a second idle state, or a connected state, so that when the UE communicates, the working mode of the UE is increased, and the working state of each SIM is controlled according to the requirement, thereby improving the utilization rate of the SIM resources.

With reference to the first aspect, in a possible implementation manner of the first aspect, the request message carries capability information of an SIM, where the SIM is an SIM in the first SIM and the second SIM whose current working state is the connected state or an SIM in the first SIM and the second SIM whose current working state is the second idle state, that is, when the SIM needs to communicate (including uplink and downlink communication and paging) with a base station, the capability information of the SIM is reported to an access network device, so as to coordinate communication resources, thereby implementing a communication process;

the capability information of the SIM comprises at least one of:

a first band combination for supporting uplink communications for the SIM, a second band combination for supporting downlink communications for the SIM, and a third band combination for supporting paging for the SIM.

In this example, the UE reports the capability information of the SIMs, so as to request the access network device to perform communication coordination, thereby maintaining normal switching of the working states of the two SIMs, ensuring that each SIM can work in any one of the three working states, increasing the communication mode of the UE, and improving user experience.

With reference to the first aspect, in a possible implementation manner of the first aspect, when the current working state of the first SIM is the connected state and the current working state of the second SIM is the first idle state, the request message carries a first frequency band combination and a second frequency band combination of the first SIM, that is, one of the two SIMs is the connected state and the other is the first idle state, the UE reports capability information of the SIM in the connected state to the access network device, and requests the access network device to allocate a communication resource to the SIM;

the first coordination result comprises a fourth frequency band combination and a fifth frequency band combination, the fourth frequency band combination is used for supporting the uplink communication of the first SIM after the UE receives the first coordination result, and the fifth frequency band combination is used for supporting the downlink communication of the first SIM after the UE receives the first coordination result;

the fourth frequency band combination is a part or all of a first frequency band combination of the first SIM, and the fifth frequency band combination is a part or all of a second frequency band combination of the first SIM.

In this example, when one of the two SIMs is in a connected state and the other is in a first idle state, the access network device is requested to allocate communication resources to the SIM in the connected state, so that the SIM has the largest communication resources, and reasonable allocation of the communication resources is realized; moreover, the communication resource coordination is carried out through the access network equipment, the participation of core network equipment is not needed, the NAS initialization process is not needed to be executed, and therefore the communication of the UE is not interrupted when the working state of the SIM is switched.

With reference to the first aspect, in a possible implementation manner of the first aspect, when the current working state of the first SIM is the connected state and the current working state of the second SIM is the second idle state, the request message carries a first frequency band combination and a second frequency band combination of the first SIM and a third frequency band combination of the second SIM, that is, when one of the two SIMs is the connected state and the other working state is the second idle state, the UE needs to report capability information of the SIM in the connected state and capability information of the SIM in the second idle state to the access network device, so as to request the access network device to coordinate communication resources;

the first coordination result comprises a fourth frequency band combination, a fifth frequency band combination and a sixth frequency band combination;

In this example, through coordination of communication resources, the UE may monitor a paging message of the SIM in the second idle state while using the SIM in the connected state for communication, so as to implement communication using two SIMs at the same time; moreover, the communication resource coordination is carried out through the access network equipment, the participation of core network equipment is not needed, the NAS initialization process is not needed to be executed, and therefore the communication of the UE is not interrupted when the working state of the SIM is switched.

With reference to the first aspect, in a possible implementation manner of the first aspect, when current operating states of the first SIM and the second SIM are both the connected states, the request message carries a first frequency band combination and a second frequency band combination of the first SIM and a first frequency band combination and a second frequency band combination of the second SIM, and the first coordination result includes a fourth frequency band combination, a fifth frequency band combination, a sixth frequency band combination, and a seventh frequency band combination, that is, when both the SIMs are in the connected states, capability information of the two SIMs needs to be reported to the access network device, so as to coordinate communication resources, and enable the UE to communicate using the two SIMs;

the fourth frequency band combination is configured to support uplink communication of the first SIM after the UE receives the first coordination result, and the fifth frequency band combination is configured to support downlink communication of the first SIM after the UE receives the first coordination result;

the sixth frequency band combination is used for supporting uplink communication of the second SIM after the UE receives the first coordination result, and the seventh frequency band combination is used for supporting downlink communication of the first SIM after the UE receives the first coordination result;

In this example, through coordination of communication resources, the UE can use two SIMs to communicate at the same time, thereby improving the utilization rate of the SIM resources; moreover, the communication resource coordination is carried out through the access network equipment, the participation of core network equipment is not needed, the NAS initialization process is not needed to be executed, and therefore, the communication of the UE is not interrupted when the working state of the SIM is switched.

"and/or" describes the association relationship of the associated objects, meaning that there may be three relationships, e.g., a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone, wherein A and B can be singular or plural. The character "/" generally indicates that the former and latter associated objects are in an "or" relationship. "at least one of the following" or similar expressions refer to any combination of these items, including any combination of the singular or plural items. For example, at least one (one) of a, b, or c, may represent: a, b, c, a-b, a-c, b-c, or a-b-c, wherein a, b, c may be single or multiple.

And, unless stated to the contrary, the embodiments of the present application refer to the ordinal numbers "first", "second", etc., for distinguishing a plurality of objects, and do not limit the sequence, timing, priority, or importance of the plurality of objects. For example, the first information and the second information are different information only for distinguishing them from each other, and do not indicate a difference in the contents, priority, transmission order, importance, or the like of the two kinds of information.

To facilitate an understanding of the present application, relevant technical knowledge related to embodiments of the present application will be first introduced herein.

In the 3GPP standardization of UTRAN, the3rd Generation Partnership Project (3 GPP), it has been agreed to transmit Radio Resource Control (RRC) signaling for UE capability information related to a Radio network, i.e., UE capability, from the UE to the NodeB. That is, in this application, user equipment capabilities may be understood as UE capabilities, which are consistent. Different UEs have different support capabilities due to different hardware or software versions, and the network side needs to know the capabilities of the UEs when making various event decisions or executing various algorithms to configure a proper working mode for the UEs to make the most appropriate decision.

The UE capabilities include various capabilities related to the RAN and various capabilities related to the CN, which may include: packet Data Convergence Protocol (PDCP) capabilities (e.g., supporting a compression header type, etc.), transport channel capabilities (e.g., maximum transport channel, received bits, etc.), and measurement capabilities (e.g., multi-carrier frequency measurement, etc.), among others. The CN-related UE capabilities may include: inter-system Packet Switch (PS) domain switching capability, and Multicast Service (MBMS) capability, among others.

As the requirements of the UE on the traffic transmission rate and the data volume become higher and higher, the network side needs the UE to report its Carrier Aggregation (CA) capability, where the CA capability includes multiple band (band) combinations. Referring to fig. 1, fig. 1 is a schematic diagram of a CA capability structure. As shown in fig. 1, the CA capability includes n types of band combinations, where n is a positive integer greater than 1, and each band combination includes different types of bands, each band corresponds to a different type of carrier combination, the different types of carrier combinations correspond to different numbers of carriers, carrier bandwidths, subcarrier spacings, and numbers of layers in a Multiple-Input Multiple-Output (MIMO) system, etc. For example, the band combination 1 includes a band 1, a band 2, and a band 3, where the carrier combination corresponding to the band 1 is of a type a, which may indicate that the UE supports only one downlink carrier, the carrier combination corresponding to the band 2 is of a type B, which may indicate that the UE supports downlink carrier aggregation of two CCs, and the carrier combination corresponding to the band 3 is of a type C, which may indicate that the UE supports downlink carrier aggregation of three CCs. The band combination 2 includes a band 1, a band 2, and a band 3, where the carrier combination corresponding to the band 1 is of a type a, the carrier combination corresponding to the band 2 is of a type D, and may indicate that the UE supports carrier aggregation of four CCs in downlink, and the carrier combination corresponding to the band 3 is of an type E, and may indicate that the UE supports carrier aggregation of 5 CCs in downlink. After acquiring the CA capability of the UE, the network side can know which frequency band combinations are specifically supported by the UE, and can perform appropriate carrier aggregation configuration for the UE according to the frequency band combinations, so as to perform communication transmission with the UE.

It should be noted that, in the technical solution of the present application, CA capability of the UE is mainly coordinated, that is, carrier aggregation capability of the UE is coordinated, but the coordinated UE capability is not limited uniquely.

Fig. 2 is a schematic diagram of a UE capability reporting process. The method comprises the steps that firstly, RRC connection is established between UE and a NodeB, the UE enters a connection state from an idle state, after the RRC connection is established, the NodeB sends UE capacity query information to an MME, after the MME receives the information, whether UE capacity information corresponding to the UE is stored or not is checked, if the MME stores the UE capacity information of the UE, the MME sends UE context establishment request information to the NodeB, the UE capacity information of the UE is carried in the information, after the NodeB receives the UE context establishment request information, the carried UE capacity information is stored, and parameters of a transmission link of the UE are modified according to the UE capacity information so that the UE can carry out data transmission. If the MME does not store the UE capability information of the UE, the MME sends a UE context establishment request message to the NodeB, the NodeB sends the UE capability request message to the UE after receiving the message and sends UE context establishment response information to the MME, the UE sends the UE capability information message to the NodeB after receiving the request message and carries the UE capability of the UE after receiving the message, the NodeB stores the carried UE capability information and sends a UE capability information indication message or a special S1 message introduced for the purpose to the MME and carries the UE capability information in the indication message or the S1 message, and the MME stores the carried UE capability information after receiving the message, thereby completing the UE capability reporting process.

When reporting the UE capability of the UE comprising a plurality of SIMs, the reported UE capability is the capability of the current SIM in the connected state every time, when switching the SIMs, the UE capability reporting process shown in FIG. 2 needs to be executed again, the capability of the SIM in the connected state after switching needs to be reported, the UE needs to request the network side to execute an NAS initialization process, the transmission link parameters of the UE are reconfigured, the communication process of the UE is interrupted, and further the user experience is reduced.

In order to understand the scheme of the present application, first, the operating state of the SIM and the capability information of the SIM are explained.

The working state of the SIM includes a first IDLE state, a second IDLE state and a CONNECTED state, the RRC state between the UE and the NodeB includes RRC _ CONNECTED and RRC _ IDLE, and in the present application, the RRC state of the UE and the RRC state of the SIM are essentially identical.

Specifically, the RRC state of the SIM is used to characterize whether the UE uses the SIM to establish an RRC connection with the NodeB, when the RRC state of the SIM is RRC _ IDLE, the UE does not use the SIM to establish the RRC connection with the base station, and when the RRC state of the SIM is RRC _ CONNECTED, the UE uses the SIM to establish the RRC connection with the NodeB; the RRC state of the SIM in the first IDLE state is RRC _ IDLE, and the UE does not use the SIM to receive the paging message of the NodeB, namely the SIM is completely in the IDLE state; the RRC state of the SIM in the second IDLE state is RRC _ IDLE, but the UE receives a paging message of the NodeB using the SIM, and the RRC state of the SIM in the CONNECTED state is RRC _ CONNECTED.

It should be noted that the NodeB mentioned above includes a NodeB in a Universal Mobile Telecommunications System (UTMS), an evolved Node B (NodeB or eNB or e-NodeB) in a Long Term Evolution (LTE) System or an LTE-a System, or may also include a next generation Node B (gNB) in a fifth generation Mobile communication technology (5G) NR System.

It should be noted that, in the 5G system, the RRC states of the UE and the gNB further include RRC _ INACTIVE, and since RRC _ INACTIVE and RRC _ IDLE do not need a large amount of communication resources as well, when the scheme of the present application is applied to the 5G system, RRC _ INACTIVE can be handled as RRC _ IDLE, and will not be described in detail.

The capability information of the SIM comprises a first frequency band combination for supporting the SIM to perform uplink communication, a second frequency band combination for performing downlink communication and a third frequency band combination for SIM paging, wherein each frequency band combination is the maximum frequency band combination of the SIM card.

Referring to fig. 3A, fig. 3A is a schematic diagram of a system architecture according to an embodiment of the present disclosure. As shown in fig. 3A, the system architecture includes user equipment 110 (including a first SIM and a second SIM) and access network equipment 120. Access network devices 120 provide wireless access services to user equipment 110, and each access network device 120 corresponds to a service coverage area in which user equipment 110 entering the area may communicate with access network device 120 via wireless signals.

Based on the system architecture shown in fig. 3A, the user equipment 110 receives the UE capability information request message sent by the access network equipment 120, and reports the UE capability, the capability of the first SIM and the capability of the second SIM to the access network equipment 120 in the form of an RRC message, and sends the UE capability, the capability of the first SIM and the capability of the second SIM to the core network equipment 130 for storage. When the working state of the first SIM and/or the working state of the second SIM are/is changed and the current working state of at least one SIM in the first SIM and the second SIM is a connected state, in order to meet the communication requirements of the two SIMs, the communication resources of the user equipment 110 need to be coordinated. The user equipment 110 sends a request message to the access network equipment 120 according to the current working state of the first SIM and the current working state of the second SIM, the access network equipment 120 is requested to coordinate the communication resources of the user equipment 110, the user equipment 110 receives response information of the access network equipment 120 responding to the request message, the response message carries a coordination result of the communication resources of the user equipment 110, and the user equipment 110 performs communication according to the coordination result, that is, the user equipment 110 performs related communication by using the first SIM and the second SIM based on the communication resources allocated to each SIM by the access network equipment 120.

In this example, when the working state of the SIM changes, the user equipment reports the current required capability information of each SIM to the access network equipment, coordinates the communication resources of the user equipment, allocates the communication resources that can be used by each SIM, and implements communication by using two SIMs at the same time, and coordinates the communication resources through the access network equipment without the participation of core network equipment, so that an NAS initialization procedure does not need to be executed, and thus, when the working state of the SIM is switched, the communication process of the user equipment is not interrupted, and further, the user experience is improved.

The method and the related device according to the embodiments of the present application are described in detail below with reference to the accompanying drawings. It should be noted that the display sequence in the embodiments of the present application only represents the sequence of the embodiments, and does not represent the advantages and disadvantages of the technical solutions provided by the embodiments.

Referring to fig. 3B, fig. 3B is a flowchart illustrating a method for coordinating communication resources according to an embodiment of the present application, where the method is applied to a UE including a first SIM and a second SIM, and the method includes, but is not limited to, the following steps:

301: and when the working state of the first SIM and/or the working state of the second SIM are/is changed, and the current working state of the first SIM is a connection state and the current working state of the second SIM is a first idle state, the UE sends a first request message to the access network equipment according to the current working state of the first SIM and the current working state of the second SIM.

Wherein, the first request message carries the capability information of the first SIM.

Specifically, the capability information of the first SIM includes a first band combination for supporting uplink communication of the first SIM and a second band combination for supporting downlink communication of the first SIM.

Specifically, the change process of the working state of the SIM is specifically described by taking six combinations of a first idle state (first SIM) + a first idle state (second SIM), a first idle state (first SIM) + a second idle state (second SIM), a first idle state (first SIM) + a connected state (second SIM), a second idle state (first SIM) + a second idle state (second SIM), a second idle state (first SIM) + a connected state (second SIM), and a connected state (first SIM) + a connected state (second SIM) as examples.

Optionally, when the current working state of the first SIM is a connected state and the current working state of the second SIM is a first idle state, the change condition of the working states of the first SIM and the second SIM may be any one of the following:

(1) the first idle state (first SIM) + the first idle state (second SIM) → the connected state (first SIM) + the first idle state (second SIM), the UE firstly establishes an RRC connection with the access network device using the first SIM, and then sends a first request message to the access network device through the first SIM.

(2) The first idle state (first SIM) + the second idle state (second SIM) → the connected state (first SIM) + the first idle state (second SIM), the UE establishes an RRC connection with the access network device using the first SIM first, and then sends a first request message to the access network device through the first SIM.

(3) The first idle state (first SIM) + connected state (second SIM) → connected state (first SIM) + first idle state (second SIM), the UE firstly establishes an RRC connection with the access network device using the first SIM, and then sends a first request message to the access network device through the first SIM.

Optionally, when the second SIM is changed from the connected state to the first idle state, the access network device synchronously releases the RRC connection of the second SIM, so as to release the communication resource occupied by the second SIM.

(4) The second idle state (first SIM) + the second idle state (second SIM) → the connected state (first SIM) + the first idle state (second SIM), the UE firstly establishes an RRC connection with the access network device using the first SIM, and then sends a first request message to the access network device through the first SIM.

(5) The second idle state (the first SIM) + the connected state (the second SIM) → the connected state (the first SIM) + the first idle state (the second SIM), the UE firstly establishes an RRC connection with the access network device using the first SIM, and then sends a first request message to the access network device through the first SIM.

Optionally, before receiving the first request message, the access network device releases the communication resource used by the second SIM.

(6) In a connected state (first SIM) + connected state (second SIM) → connected state (first SIM) + first idle state (second SIM), when the first SIM is in the connected state and the second SIM is in the connected state, communication resources of the UE are originally occupied by the two SIMs, and when the second SIM is changed from the connected state to the first idle state, the access network device releases all communication resources occupied by the second SIM, and the part of communication resources are in the idle state. At this time, in order to reasonably utilize the communication resources of the UE, the UE may send first request information to the access network device, request the access network device to coordinate the communication resources of the UE, and allocate more communication resources to the first SIM to support communication of the first SIM.

Specifically, when sending the first request message, the UE may send the first request message to the access network device through the RRC layer of the first SIM, where the UE may send the first request message to the access network device in the form of an RRC message.

Optionally, when the first request message is sent to the access network device in the form of an RRC message, the first frequency band combination of the first SIM carried by the first request message may be specific frequency band information of the first frequency band combination, or identification information of the first frequency band combination.

For example, when the first band combination is the band combination 1 shown in fig. 1, the RRC message may carry the number of carriers per band of the band 1, the band 2, and the band 3, the carrier credit, the number of MIMO layers, etc. in the band combination 1, or carry identification information corresponding to the band combination 1, for example, N1 corresponding to the band combination 1, M1 representing the bandwidth of the band 1 and the band combination 1, K1 representing the number of carriers of the band combination 1, and L1 representing the number of MIMO layers of the band combination 1, N1, M1, K1, and L1, that is, specific information of the first band combination that can inform the access network device of the first SIM, may be carried in the RRC message.

302: and the access network equipment coordinates the communication resources of the UE according to the first request message.

Optionally, after receiving the first request message, the access network device parses the first request message to obtain a first frequency band combination of the first SIM, and coordinates the communication resource of the UE according to the stored CA capability of the UE, the first frequency band combination of the first SIM, and the communication resource in the area managed by the access network device to obtain a first coordination result.

For example, the CA capability of the UE is related to UE type (format), the capability information of the first SIM is related to RAT type of the SIM, such as the band combination supported by the UE can be band combination 1-band combination n, wherein, the frequency band combination 1-frequency band combination j is used for supporting the uplink communication, the frequency band combination j + 1-frequency band combination n is used for the downlink communication, and the first SIM belongs to a mobile operator, the supported band combination may be band combination 1-band combination m, m < n, wherein, the frequency band combination 1-frequency band combination i is used for supporting the uplink communication, the frequency band combination i + 1-frequency band combination m is used for supporting the downlink communication, when the UE uses the first SIM for communication, the access network device needs to coordinate uplink communication resources for the first SIM in band combination 1 to band combination j supported by the UE, coordinating downlink communication resources for the first SIM in band combination j +1 through band combination n.

The following describes the coordination of uplink resources in detail.

When it is determined that the band combination 1 to the band combination i are all band combinations supported by the UE and each band combination has an idle band, the UE is allowed to support uplink communication of the first SIM using all of the band combinations 1 to the band combination i, when the band combination 1 to the band combination i are all band combinations supported by the UE but only some of the band combinations 1 to the band combination i (e.g., the band combination 1 to the band combination k, k < i) have idle bands, the band combination 1 to the band combination k is coordinated to the first SIM so that the UE supports uplink communication of the first SIM using the band combination 1 to the band combination k, and when it is determined that the band combination 1 to the band combination i do not have an idle band, the response to the first request message is rejected.

Further, the communication resources are coordinated to obtain a first coordination result, where the first coordination result includes a fourth frequency band combination and a fifth frequency band combination that can be used by the first SIM card, where the fourth frequency band combination is used to support uplink communication of the first SIM after the UE receives the first coordination result, and the fifth frequency band combination is used for downlink communication of the first SIM after the UE receives the first coordination result, and because other communication devices occupy the communication resources and there may be overlapping frequency band combinations in the two SIMs, the fourth frequency band combination is part or all of the first frequency band combination of the first SIM, and the fifth frequency band combination is part or all of the second frequency band combination of the first SIM.

303: the access network equipment sends response information responding to the first request message to the UE.

Wherein, the response information carries the first coordination result.

Specifically, the response information may be sent to the UE in the form of an RRC message, similarly, the specific information of the first coordination result may be sent to the UE in the form of an RRC message, or the identification information corresponding to the first coordination result may be sent to the UE in the form of an RRC message, and after the UE analyzes the identification information, the specific information of the first coordination result may be obtained, which is not described again.

In this example, when the working states of the first SIM and/or the second SIM are changed, and the current working state of the first SIM is a connected state, and the current working state of the second SIM is a first idle state, the access network device dynamically coordinates the communication resources of the UE according to the working states of the two SIMs to maintain the normal working states of the two SIMs, so as to improve the utilization rate of the SIM resources.

Referring to fig. 4, fig. 4 is a flowchart illustrating another method for coordinating communication resources according to an embodiment of the present application, where the method is applied to a user equipment UE including a first SIM and a second SIM, and the method includes, but is not limited to, the following steps:

401: and when the working state of the first SIM and/or the working state of the second SIM are/is changed, and the current working state of the first SIM is a connection state and the current working state of the second SIM is a second idle state, the UE sends a second request message to the access network equipment according to the current working state of the first SIM and the current working state of the second SIM.

And the second request message carries the capability information of the first SIM and the capability information of the second SIM.

Specifically, the capability information of the first SIM includes a first band combination and a second band combination of the first SIM, and a third band combination of the second SIM.

Optionally, referring to 301, when the current operating state of the first SIM is the connected state and the current operating state of the second SIM is the second idle state, the change condition of the operating states of the first SIM and the second SIM may be any one of the following:

(1) the first idle state (first SIM) + the first idle state (second SIM) → the connected state (first SIM) + the second idle state (second SIM), the UE firstly establishes an RRC connection with the access network device using the first SIM, and then the UE sends a second request message to the access network device through the first SIM.

(2) The first idle state (first SIM) + the second idle state (second SIM) → the connected state (first SIM) + the second idle state (second SIM), the UE firstly establishes an RRC connection with the access network device using the first SIM, and then the UE sends a second request message to the access network device through the first SIM.

(3) The first idle state (the first SIM) + the connected state (the second SIM) → the connected state (the first SIM) + the second idle state (the second SIM), the UE firstly establishes an RRC connection with the access network device using the first SIM, and then sends a second request message to the access network device through the first SIM.

Optionally, when the second SIM changes from the connected state to the idle state, the access network device releases the communication resource occupied by the second SIM.

(4) The second idle state (the first SIM) + the second idle state (the second SIM) → the connected state (the first SIM) + the second idle state (the second SIM), the UE firstly establishes the RRC connection with the access network device using the first SIM, and then, the UE sends the second request message to the access network device through the first SIM.

(5) In a second idle state (first SIM) + connected state (second SIM) → connected state (first SIM) + second idle state (second SIM), the UE establishes an RRC connection with the access network device using the first SIM, and then, the UE sends a second request message to the access network device through the first SIM.

Optionally, before the UE establishes the RRC connection with the access network device using the first SIM, the access network device releases the RRC connection with the second SIM to release the communication resources occupied by the second SIM.

(6) Connected state (first SIM) + connected state (second SIM) → connected state (first SIM) + second idle state (second SIM), when the first SIM remains connected and the second SIM is also in connected state, communication resources of the UE are originally occupied by the two SIMs, and when the second SIM changes from connected state to second idle state, the access network device may release the communication resources occupied by the second SIM. In addition, the UE needs to use the second SIM to monitor the paging message, and at this time, in order to maintain the first SIM in the connected state and the second SIM in the second idle state, the UE sends the capability information of the first SIM and the second capability information of the second SIM to the access network device, requests the access network device to coordinate the communication resources of the UE, and allocates corresponding communication resources to each SIM, so that each SIM uses the communication resources allocated to communicate.

402: and the access network equipment coordinates the communication resources of the UE according to the second request message.

Optionally, after receiving the second request message, the access network device coordinates the communication resource according to the second request message to obtain the first coordination result.

Specifically, referring to 302, the access network device parses the second request message to obtain a first frequency band combination and a second frequency band combination of the first SIM and a third frequency band combination of the second SIM, coordinates the uplink frequency band combination supported by the UE according to the stored CA capability of the UE, the first frequency band combination of the first SIM and the communication resources in the management area of the access network device to obtain a fourth frequency band combination for supporting the uplink communication of the first SIM, and coordinates the downlink frequency band combination supported by the UE according to the stored CA capability of the UE, the second frequency band combination of the first SIM, the third frequency band combination of the second SIM and the communication resources in the management area of the access network device to obtain a fifth frequency band combination for supporting the downlink communication of the first SIM and a sixth frequency band combination for supporting the paging of the second SIM.

The fourth frequency band combination is part or all of the first frequency band combination of the first SIM, the fifth frequency band combination is part or all of the second frequency band combination of the first SIM, and the sixth frequency band combination is part or all of the third frequency band combination of the second SIM.

403: the access network equipment sends response information responding to the second request message to the UE.

Wherein the response information carries the first coordination result.

Optionally, the response message may be sent to the UE in the form of an RRC message.

In this example, when the working state of the first SIM and/or the second SIM changes, and the current working state of the first SIM is a connected state, and the current working state of the second SIM is a second idle state, the access network device coordinates communication resources required by the first SIM and the second SIM, so as to implement synchronous working of the two SIMs, and improve the utilization rate of SIM resources.

Referring to fig. 5, fig. 5 is a flowchart illustrating another method for coordinating communication resources according to an embodiment of the present application, where the method is applied to a user equipment UE including a first SIM and a second SIM, and the method includes, but is not limited to, the following steps:

501: and when the working state of the first SIM and/or the working state of the second SIM are/is changed, and the current working state of the first SIM is a connection state and the current working state of the second SIM is a connection state, the UE sends a third request message to the access network equipment according to the current working state of the first SIM and the current working state of the second SIM.

And the third request message carries the capability information of the first SIM and the capability information of the second SIM.

Specifically, the capability information of the first SIM includes a first band combination and a second band combination of the first SIM, and a first band combination and a second band combination of the second SIM.

(1) the first idle state (first SIM) + the first idle state (second SIM) → the connected state (first SIM) + the connected state (second SIM), the UE establishes an RRC connection with the access network device using the first SIM and the second SIM, respectively, and then sends the third request message to the access network device through the primary SIM in the first SIM and the second SIM.

The main SIM may be set by the user, or may be set by the system automatically, for example, the SIM in the card slot 1 is set as the main SIM, and the embodiment of the present application does not limit the manner of setting the main SIM.

(2) First idle state (first SIM) + second idle state (second SIM) → connected state (first SIM) + connected state (second SIM). The UE establishes RRC connection with the access network equipment by using the first SIM and the second SIM respectively, and then sends a third request message to the access network equipment through a main SIM in the first SIM and the second SIM.

(3) The first idle state (first SIM) + connected state (second SIM) → connected state (first SIM) + connected state (second SIM), the UE establishes an RRC connection with the access network device using the first SIM and the second SIM, respectively, and then sends the third request message to the access network device through the primary SIM of the first SIM and the second SIM.

(4) The second idle state (first SIM) + the second idle state (second SIM) → connected state (first SIM) + connected state (second SIM), the UE establishes an RRC connection with the access network device using the first SIM and the second SIM, respectively, and then sends the third request message to the access network device through the primary SIM of the first SIM and the second SIM.

(5) Connected state (first SIM) + first idle state (second SIM) → connected state (first SIM) + connected state (second SIM), when the first SIM keeps the connected state all the time and the second SIM changes from the first idle state to the connected state, the UE originally uses only the first SIM for communication, so the first SIM occupies all communication resources of the UE, and when the second SIM changes from the first idle state to the connected state, the UE competes with the first SIM for communication resources of the UE. At this time, in order to use two SIMs for communication simultaneously, the UE reports capability information of the two SIMs to the access network device through a first SIM (master SIM), requests the access network device to coordinate communication resources of the UE according to the capability information of each SIM, and allocates corresponding communication resources to each SIM, so that each SIM uses the communication resources allocated to itself for communication.

(6) When the first SIM is always in the connected state and the second SIM is changed from the second idle state to the connected state, the UE originally only uses the second SIM to monitor the paging message, so that the second SIM only occupies downlink communication resources for supporting paging in the downlink communication resources of the UE, and when the second SIM is changed from the second idle state to the connected state, the communication resources required by the second SIM are changed and need to compete with the first SIM for the communication resources of the UE. At this time, in order to use two SIMs for communication simultaneously, the UE reports capability information of the two SIMs to the access network device through a first SIM (master SIM), requests the access network device to coordinate communication resources of the UE according to the capability information of each SIM, and allocates corresponding communication resources to each SIM, so that each SIM uses the communication resources allocated to itself for communication.

502: and the access network equipment coordinates the communication resources of the UE according to the third request message.

Optionally, after receiving the third request message, the access network device coordinates the communication resource of the UE according to the third request message to obtain a first coordination result.

Specifically, referring to 302, the access network device parses the third request message to obtain a first band combination and a second band combination of the first SIM, and a first band combination and a second band combination of the second SIM, and coordinates the uplink band combination supported by the UE according to the stored CA capability of the UE, the first band combination of the first SIM, the second band combination of the second SIM, and the communication resource in the area managed by the access network device to obtain a fourth band combination for supporting the uplink communication of the first SIM and a sixth band combination for supporting the uplink communication of the second SIM; and coordinating the downlink frequency band combination supported by the UE according to the stored CA capability of the UE, the second frequency band combination of the first SIM, the second frequency band combination of the second SIM and the communication resources in the management area of the access network equipment to obtain a fifth frequency band combination for supporting the downlink communication of the first SIM and a seventh frequency band combination for supporting the downlink communication of the second SIM.

The fourth frequency band combination is part or all of the first frequency band combination of the first SIM, the fifth frequency band combination is part or all of the second frequency band combination of the first SIM, the sixth frequency band combination is part or all of the first frequency band combination of the second SIM, and the seventh frequency band combination is part or all of the second frequency band combination of the second SIM.

503: and the access network equipment sends response information responding to the third request message to the UE.

Wherein the response information carries the first coordination result.

In this example, when the working states of the first SIM and/or the second SIM are changed and the current working states of the first SIM and the second SIM are connected, the access network device coordinates communication resources required by the first SIM and the second SIM, so that the two SIMs simultaneously work in the connected state, so that the communication function of each SIM is utilized, the utilization rate of the SIM resources is improved, and the requirement of a user on multiple communications is met; in addition, when the working state of the SIM is switched, the communication resources are coordinately allocated through the access network equipment without the participation of core network equipment, so that the NAS initialization flow is not required to be executed, the communication process of the user equipment is not interrupted, and the user experience is further improved.

In some possible embodiments, when the working state of the first SIM and/or the working state of the second SIM are/is changed, and the current working state of the first SIM is the first idle state and the current working state of the second SIM is not the connection state, the method further includes: and the UE coordinates the communication resources of the UE according to the current working states of the first SIM and the second SIM to obtain a second coordination result.

Optionally, when the current operating states of the first SIM and the second SIM are the first idle state and the second idle state, respectively, the second coordination result includes an eighth frequency band combination, and the eighth frequency band combination is used to support paging of the second SIM, where the eighth frequency band combination is part or all of a third frequency band combination of the second SIM.

Specifically, if the first SIM and the second SIM are changed from the connected state to the current state, the base station releases the RRC connection with the first SIM and the second SIM, so that the UE does not use any SIM to establish the RRC connection with the access network device, and therefore cannot report a request message to the access network device, and the UE needs to autonomously coordinate communication resources.

For example, when the first SIM is in the first idle state and the second SIM receives the paging message, the UE may allocate a frequency band combination for supporting paging in the UE communication resource to the second SIM, so that the UE listens to the paging message of the second SIM in the frequency band combination and uses the eighth frequency band combination as the frequency band combination for supporting paging of the second SIM, so that the eighth frequency band combination is part or all of the third frequency band combination of the second SIM.

Optionally, when the current operating states of the first SIM and the second SIM are both the second idle state, the second coordination result includes an eighth frequency band combination and a ninth frequency band combination, where the eighth frequency band combination is used to support paging of the first SIM, the ninth frequency band combination is used to support paging after the second SIM, the eighth frequency band combination is part or all of the third frequency band combination of the first SIM, and the ninth frequency band combination is part or all of the third frequency band combination of the second SIM.

Specifically, when the first SIM and the second SIM are both in the second idle state, the UE needs to monitor paging of the first SIM and the second SIM, so that the frequency band combination for supporting paging in the UE communication resource needs to be coordinated, and the communication resource may be coordinated in a time division multiplexing or frequency division multiplexing manner, so as to obtain an eighth frequency band combination for supporting paging of the first SIM and a ninth frequency band combination for supporting paging of the second SIM.

For example, when the first SIM and the second SIM are SIMs of different operators, the corresponding frequency band combinations are different, so that the corresponding SIMs may be awakened in different time periods respectively in a time division multiplexing manner, and a paging message of the SIM is monitored in the frequency band combination of the SIM, and when the first SIM and the second SIM are SIMs of the same operator, the same frequency band combination is used, and corresponding communication resources are allocated to the first SIM and the second SIM in a frequency division multiplexing manner, so that the eighth frequency band combination is a part or all of the third frequency band combination of the first SIM, and the ninth frequency band combination is a part or all of the third frequency band combination of the second SIM.
