Communication method and device

Technical Field

The present disclosure relates to the field of communications technologies, and in particular, to a communications method and apparatus.

Background

In the long term evolution (long term evolution, LTE) wireless communication specifications set by the third generation partnership project (the 3rd generation partnership project,3GPP), when a User Equipment (UE) is not engaged in a call or accessing the internet, an idle state is entered for power saving. In the idle state, the UE is in a sleep state most of the time, and only periodically wakes up to receive paging (paging) messages at the system side at Paging Occasion (PO) time points, and if no paging message of the UE exists, the UE continues to sleep to reduce power consumption.

At present, there are two cards on a physical terminal device, namely a main card and an auxiliary card, where the main card and the auxiliary card may belong to the same operator or may belong to different operators. When the main card and the sub card belong to the same operator, for the UE, it is assumed that the two UEs execute the same signaling flow, for example, when receiving paging messages, in the prior art, the two UEs are independent from each other, for example, the two UEs are UE1 and UE2 respectively, the PO of the UE1 is PO1, the PO of the UE2 is PO2, that is, the UE1 wakes up to receive the paging message of the UE1 at the PO1 time point, and the UE2 wakes up to receive the paging message of the UE2 at the PO2 time point, so that the signaling overhead of the UE is relatively large and the power consumption is relatively large.

For convenience of description, in the embodiment of the present application, two cards (a primary card and a secondary card) located in the same entity terminal device are understood as two UEs, i.e., a first UE and a second UE. Of course, the first UE may be any one of the primary card and the secondary card, that is, when the first UE is the primary card, the second UE is the secondary card, and when the first UE is the secondary card, the second UE is the primary card.

It should be noted that, the communication method provided in the embodiment of the present application may be applicable to a dual-card scenario, or may be applicable to a multi-card (three-card or more) scenario, where only dual-card is taken as an example for illustration.

S21: the first UE sends a first message to the network device, which receives the first message from the first UE.

The first message is used for indicating the binding relation between the first UE and the second UE, and the first message can carry the first identification information of the first UE and the first identification information of the second UE. In the embodiment of the application, the binding relationship between the first UE and the second UE may be indicated by the first identification information of the first UE and the first identification information of the second UE. Alternatively, the binding relationship of the first UE and the second UE may be indicated by the displayed indication field, and the first identification information of the first UE and the first identification information of the second UE may be indicated at the same time.

In the embodiment of the present application, the first identification information of the first UE and the first identification information of the second UE may include, but are not limited to, the following identification information: a 5G globally unique temporary identity (globally unique temporary identifier, GUTI), a permanent terminal identity (permanent equipment identity, PEI), a 5G temporary mobile subscriber identity (S-temporary mobile subscription identifier, S-TMSI), an inactive radio network temporary identity (inactive radio network temporary identifier, I-RNTI), an international mobile subscriber identity (international mobile subscriber identity, IMSI).

Before step S21, in the embodiment of the present application, the second UE may send the first identification information to the first UE, or may also send the first identification information of the first UE to the second UE, and at the same time, send the first identification information of the second UE to the first UE.

S22: the network device configures a paging relationship for the first UE and the second UE.

After the network device receives the first message, the first UE and the second UE may be configured according to the binding indicated by the first message. In particular, the network device may indicate that paging messages for both cards are received by one of the cards and by which card the paging message is received, e.g., may indicate that the paging message is received by the first UE, or may indicate that the paging message is received by the master card, or may indicate which UE is receiving the paging message depending on the connection state (connected state or idle state) of the UE.

Configuring the paging relation of the first UE and the second UE for the network device may include the following three cases:

first case: when two cards are simultaneously in a connected (connected) state, the network device may instruct reception of a paging message by either card. For example, the network device may instruct reception of the paging message at the master card, and assuming the master card is the first UE, the paging message of itself and the paging message of the second UE may be received by the first UE. Of course, it is understood that the master card may also be the second UE, which is not limited in this application.

Second case: when two cards are simultaneously in an idle state, the network device may instruct reception of a paging message by either card. For example, the network device may instruct reception of the paging message at the secondary card, and assuming the secondary card is the first UE, the paging message of itself and the paging message of the second UE may be received by the first UE. Of course, it is understood that the secondary card may also be the second UE, which is not limited in this application.

Third case: when one of the two cards is in a connected state and the other card is in an idle state, the network device may instruct the reception of the paging message by the card in which the card is in the connected state. For example, if the main card is in connected state, the sub card is in idle state, the main card is the first UE, the sub card is the second UE, and the first UE (main card) receives its paging message and the paging message of the second UE (sub card).

S23: the network device sends a second message to the first UE, which receives the second message.

The second message is used for indicating and confirming paging binding of the first UE and the second UE, and the second message may carry a configuration result of the network device, that is, which card receives the paging message, for example, confirms that the first UE receives the paging message of the first UE and the paging message of the second UE.

Optionally, after receiving the second message, the first UE may send the second message to the second UE, or send the configuration result of the network device to the second UE. Alternatively, the network device may also send a second message to the second UE, which receives the second message. For example, acknowledging receipt of the paging message of the first UE and the paging message of the second UE by the first UE, the second UE need not itself receive the paging message of the second UE.

S24: the network device sends a paging message to the first UE.

S25: the first UE receives a paging message at a first paging occasion.

For convenience of description, the timing of the first UE receiving the paging message is referred to as a first paging timing (PO) and the timing of the second UE receiving the paging message is referred to as a second paging timing.

The first paging occasion and the second paging occasion may be the same or different, which is not limited in this application.

In the embodiment of the present application, the first UE may be instructed to receive the paging message of the first UE and the paging message of the second UE, that is, the first UE receives the paging message of the first UE and the paging message of the second UE at the first paging occasion. It is understood that the paging message includes the paging message of the second UE and the paging message of the first UE. Thus, the first UE can receive the paging message of the second UE at the first paging occasion, so that the second UE does not need to wake up to receive the paging message at the paging occasion, thereby reducing signaling overhead and reducing power.

Further, the first UE may acquire second identification information of the second UE, where the second identification information is identification information carried in the paging message, and the first UE acquires second identification information of the second UE carried in the paging message, and may determine whether the second UE is paged. And if the paging message carries the identification information of the second UE, determining that the second UE is paged. Similarly, if the paging message carries the second identification information of the first UE, it is determined that the first UE is paged.

Wherein, the second identification information can be any one of the following identification information: IMSI, S-TMSI, I-RNTI.

The second identification information is the identification information of the UE carried in the paging message, and may be the same as or different from the first identification information, which is not limited in this application.

In the embodiment of the present application, the network device may be a base station or a core network, and the communication method related to the present application will be described in detail below by taking the core network and the base station as examples. Referring to fig. 3, the method specifically includes the following steps:

s31: the first UE sends a message 1 to the core network device, and the core network device receives the message 1.

In the application, a first UE sends a non-access stratum (NAS) message to a core network device, where the NAS message may be used to indicate a binding relationship between the first UE and a second UE.

Before step S31, the first UE and the second UE may interact with the first identification information, and then when the first UE sends the message 1 to the core network device, the first identification information of the first UE and the first identification information of the second UE may be carried in the message 1.

It is to be understood that the first UE is either one of two UEs (two cards).

S32: the core network device sends a message 1 to the base station.

S33: and the base station configures the paging relation of the first UE and the second UE according to the message 1.

After receiving message 1 (NAS message), the core network device may send the message to the base station, where the base station configures the paging relationship of the first UE and the second UE. As one example, the base station may instruct the primary card to receive a paging message for the primary card and a paging message for the secondary card.

S34: the base station sends a message 2 to the first UE.

After the base station completes configuration of the paging relation between the first UE and the second UE, the configured paging relation may be sent to the UE that receives the paging message.

Assuming that the primary card is the first UE, the base station indicates to acknowledge receipt of the paging message by the first UE, and the base station may send the configuration result to the first UE. It will be appreciated that the configuration result indicates which card acknowledges receipt of the paging message.

S35: the base station sends a message 3 to the first UE.

The base station transmits a message 3, i.e., a paging message, to the first UE, which may receive the paging message of the first UE and the paging message of the second UE at the first paging occasion. The paging message may carry UE identification information, and if the UE identification information carried in the paging message is the first UE identification information and/or the second UE identification information, it is determined that the first UE and/or the second UE is paged.

In this embodiment of the present application, the first UE may acquire the second identification information of the second UE, that is, the first UE acquires the identification information of the second UE carried in the paging message of the second UE, so that it may determine whether the second UE is paged, and send a result of whether the second UE is paged to the second UE.

Referring to fig. 4, a flowchart of another communication method provided in an embodiment of the present application may specifically include the following steps:

It should be noted that, steps S41 and S44 are the same as steps S31 and S35, and specific reference may be made to the related description in the method embodiment of fig. 3, and the detailed description is not repeated here.

S41: the first UE sends a message 1 to the core network device, and the core network device receives the message 1.

S42: the core network device configures the paging relation between the first UE and the second UE according to the message 1.

In the embodiment of the present application, the core network device may also configure the paging relationship between the first UE and the second UE according to the NAS message. In particular, the core network device may indicate which card receives the paging messages of the primary and secondary cards. I.e. the core network device indicates by which UE the paging message of the first UE and the paging message of the second UE are received.

S43: the core network device sends a message 2 to the base station, and the core network device or the base station sends the message 2 to the first UE.

In this step, the following two cases may be specifically included:

first case: after the core network device completes the configuration of the paging relation between the first UE and the second UE, the core network device may send a message 2 to the base station, where the message 2 may be understood as a configuration result. Meanwhile, the core network device may send a message 2 to the designated UE, notifying the designated UE of the configuration result. Specifically, the message 2 is sent by the core network device to the base station, and then forwarded by the base station to the designated UE, where the base station only forwards the message 2 transparently without parsing the message 2.

Second case: after the core network device completes the configuration of the paging relationship between the first UE and the second UE, the core network device may first send a message 2 to the base station, and then the base station sends the message 2 to the specified UE, and notifies the specified UE of the configuration result.

Assuming that the configuration result is that the paging message is received by the first UE, message 2 may be transmitted to the first UE, i.e., the first UE is informed to receive the paging message of itself and to receive the paging message of the second UE.

S44: the base station sends a message 3 to the first UE, wherein the message 3 is a paging message.

After the base station receives message 2, a paging message may be sent to the indicated UE, e.g., to the first UE.

As shown in fig. 5, a flowchart of another communication method provided in an embodiment of the present application may specifically include the following steps:

s51: the first UE sends message 1 to the base station.

In the embodiment of the present application, a first UE may send an Access Stratum (AS) message to a base station, where the AS message may be used to indicate a binding relationship between the first UE and a second UE.

S52: and the base station configures the paging relation between the first UE and the second UE according to the message 1.

S53: the base station sends a message 2 to the first UE.

S54: the base station sends a message 3 to the first UE.

It should be noted that, the steps S52 to S54 are the same as the steps S33 to S35, and the description of the method embodiment of fig. 3 can be referred to specifically, and the detailed description is not repeated here.

Fig. 6 is a flowchart of a communication method according to an embodiment of the present application. Step S61 is the same as step S51, and steps S63 to S65 are the same as steps S42 to S44, and the description of the method embodiment of fig. 4 will be referred to specifically, and the detailed description is not repeated here.

S61: the first UE sends message 1 to the base station.

S62: the base station sends a message 1 to the core network device.

After receiving the AS message, the base station may send the AS message to the core network device, where the core network device configures the paging relationship between the first UE and the second UE.

S63: the core network device configures the paging relation between the first UE and the second UE according to the message 1.

S64: the core network device sends a message 2 to the base station, and the core network device or the base station sends the message 2 to the first UE.

S65: the base station sends a message 3 to the first UE.

It should be noted that, the steps involved in the embodiments shown in fig. 3 to 6 may be further specifically described with reference to the method embodiment of fig. 2, which is not described herein.

Based on the above embodiments, the present application further provides a communication method, referring to fig. 7, including the following steps:

s71: the first UE determines to receive a paging message for the second UE.

In the embodiment of the application, the first UE and the second UE perform information interaction, and the paging message of the second UE is determined to be received by the first UE; or, the first UE may be preset to receive the paging message of the second UE, for example, the first UE may be preset to receive the paging message of the secondary card from the primary card, and may be other preset modes, which are not described herein in detail.

S72: the first UE receives a second paging message sent by the network equipment at a second paging occasion.

In the method, the first UE determines to receive the paging message of the second UE, and the first UE may receive the second paging message sent by the network device at the second paging occasion. The second paging message includes a paging message of the second UE, and an opportunity of the second UE for receiving the paging message is a second paging opportunity. Thus, the first UE can receive the paging message of the second UE at the PO of the second UE and send the received paging message to the second UE, so that the second UE does not need to wake up to receive the paging message at the paging occasion of the second UE, thereby reducing signaling overhead and reducing power consumption.

Further, the first UE may also receive a first paging message of the first UE at the first paging occasion. The first paging message includes a paging message of the first UE, and an opportunity of the first UE for receiving the paging message is a first paging opportunity.

Optionally, the first UE may receive information of a second paging occasion sent by the second UE.

Wherein the information of the second paging occasion includes at least one of the following information: paging occasion of the second UE, identification information of the second UE, discontinuous receiving period information and offset information.

It should be noted that the second Paging Occasion (PO) may be calculated by parameters such as discontinuous reception cycle information (DRX cycle), identification information (5G-S-TMSI or 5G-S-TMSI mod 1024) of the second UE, and offset information (pf_offset).

When the UE is in an idle state, if the UE needs to be paged, the core network can page all cells of a tracking area where the UE is located, namely all base stations in the tracking area can receive a paging message, and then the base stations send the received paging message to the UE so as to page the UE. Since the location of the terminal device may change, the tracking area TA of the UE may change along with the change of the location of the terminal device, which may be understood as that the tracking area needs to be updated.

Based on the above embodiments, the embodiments of the present application further provide a communication method, as shown in fig. 8, which specifically may include the following steps:

s81: the first UE sends a registration request message to the core network device.

The registration request message is used for indicating to update the positions of the first UE and the second UE, and the registration request message can comprise identification information of the first UE and identification information of the second UE. The identification information of the first UE and the identification information of the second UE may be any one of the identification information listed in step S21.

It should be understood that, when updating the location, the identification information of the first UE and the identification information of the second UE need to be updated simultaneously. For example, the GUTI of the first UE and the second UE may be updated.

S82: the core network device sends a registration accept message to the first UE.

The registration acceptance message may include identification information after the first UE performs the location update and/or identification information after the second UE performs the location update.

It should be noted that, in step S82, the core network device may or may not reassign the identifiers of the first UE and the second UE after receiving the registration request message, so that when the core network device sends the registration accept message to the first UE, if the identifier information of the first UE and/or the second UE is reassigned, the registration accept message may carry the identifier information after the location update of the first UE and/or the identifier information after the location update of the second UE.

Optionally, the core network device may also send the reassigned identification information to the base station, and the base station may then configure the paging relationship between the first UE and the second UE, instruct one of the UEs to receive the paging message, and send the paging message to the indicated UE.

In the embodiment of the application, the registration request message carries the identification information of the first UE and the identification information of the second UE, so that the core network can update the positions of the first UE and the second UE at the same time, and the two UEs do not need to be updated independently, thereby reducing signaling overhead and improving updating efficiency.
