Description

Paging method and device

The present application claims priority to Chinese Patent Application No. 200910278590.8, entitled "A Method and Apparatus for Transmitting Paging Information", filed on April 25, 2017, the entire contents of In this application.

Technical field

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

Background technique

In the Long Term Evolution (LTE) wireless communication technology specification developed by the 3rd Generation Partnership Project (3GPP), when a user equipment (User Equipment, UE) is not in a call or access When the Internet is on, it enters the idle state to save power. In the idle state, the UE's wireless transceiver is in a dormant state most of the time, and only periodically wakes up at the Paging Occasion (PO) time point to try to receive the paging message on the system side, if there is no UE. The paging message continues to sleep. The PO time point is calculated by the UE and the base station according to the same parameters known to both parties.

An application scenario in which the UE is used as a relay is proposed in the LTE R14 version. The wearable device also accesses the network through cellular communication technologies such as LTE. In order to reduce power consumption, the wearable device tries to connect to the user's mobile phone and access the cellular network through the user's mobile phone. The user's mobile phone is a relay user equipment (Relay UE), and the wearable device connected to the mobile phone is called a remote user equipment (Remote UE).

After the remote UE is connected to the relay UE, if there is no communication and enters the idle state to save power, both the network side and the relay UE know the current state of the remote UE. The remote UE also needs to wake up periodically to receive the paging message when it is in the idle state.

In order to allow the remote UE that does not access the relay UE to discover the relay UE, or let the remote UE that has been connected to the relay UE determine whether it is still in the vicinity of the relay UE, the relay UE periodically sends a discovery message ( Discovery Message). The discovery message includes information such as the identity of the relay UE.

In a solution, the remote UE connected to the relay UE can still wake up to receive the paging message from the base station at the PO time point jointly calculated by the base station in the idle state, and the remote UE needs to be relayed again. When the UE wakes up to receive the discovery message at the time when the UE sends the discovery message, the remote UE wakes up more times and consumes more power.

In another solution, the relay UE may receive the paging message of the remote UE from the base station instead of the remote UE, and then forward the paging message to the remote UE, that is, the relay UE, at the PO time jointly calculated by the relay UE and the remote UE. The remote UE plays the role of a base station. At this time, the remote UE needs to wake up at the PO time point negotiated with the relay UE to try to receive its own paging message, and needs to wake up to receive the discovery message at the time when the relay UE sends the discovery message, and the remote UE Wake up more times and consume more power.

Summary of the invention

After the remote UE is connected to the relay UE, if it does not communicate with other devices, it will enter the idle state to save power. However, when the remote UE is in the idle state, it needs to wake up periodically to receive the paging message sent by the base station. The remote UE wakes up more frequently than the discovery message sent by the UE, resulting in a large power consumption of the remote UE.

In view of the above problems, the embodiment of the present application provides a paging method and apparatus, which solves the problem that the existing remote UE frequently wakes up to receive paging messages and discover messages when the UE accesses the network by the relay UE, resulting in large power consumption. . The method and the device are based on the same concept. Since the principles of the method and the device for solving the problem are similar, the implementation of the device and the method can be referred to each other, and the repeated description is not repeated.

FIG. 1b is a schematic flowchart of a paging method provided by an embodiment of the present application. The process may be implemented by hardware, software programming, or a combination of hardware and software.

The functional modules for performing the paging scheme provided by the embodiments of the present application may be specifically implemented by hardware, software programming, and a combination of hardware and software, and the hardware may include one or more signal processing and/or application specific integrated circuits.

As shown in FIG. 1b, the process specifically includes the following processes:

Step 11: The relaying UE obtains the first device identifier of the remote UE. In this application, the UEID is used to indicate the first device identifier of the remote UE.

It should be noted that a first device identifier uniquely identifies a remote user device in a global scope.

Optionally, the UEID may be a SAE-Temporary Mobile Subscriber Identity SAE (System Architecture Evolution, S-TMSI) or an International Mobile Subscriber Identity (IMSI).

The implementation manner of the UE that obtains the UE ID of the remote UE may include, but is not limited to, the following two types:

Implementation 1: The remote UE first connects to the base station, and obtains the S-TMSI allocated by the network side to the remote UE. Then, the remote UE discovers the relay UE, and requests to establish an end-to-end with the relay UE (Device-to-Device). , D2D) connection. The relay UE may obtain the UE ID of the remote UE in the process of establishing a D2D connection with the remote UE. Optionally, the remote UE may place the UE ID in the request message requesting the establishment of the D2D connection to enable the relay UE to obtain the far The UE ID of the UE, or the remote UE reports its own UEID to the relay UE after establishing a D2D connection with the relay UE.

Implementation 2: The remote UE discovers the relay UE, and accesses the network through the relay UE, and also establishes a D2D connection with the relay UE. At this time, the relay UE can interact with the base station by the remote UE through the relay UE. Obtaining the S-MTSI of the remote UE sent by the base station to the remote UE. Of course, the relay UE may not parse the message that the remote UE interacts with the base station by using the relay UE. At this time, the remote UE requests the establishment of the D2D connection to the relay UE after the UE is accessed by the relay UE, and is established. The D2D connection transmits its own UEID to the relay UE at the same time or after.

In summary, the relay UE can obtain the UE ID of the remote UE from the remote UE, and obtain the UE ID of the remote UE from the base station. This application does not limit how the relay UE obtains the UE ID of the remote UE. At the same time, the network side sends the first device identifier (S-TMSI or IMSI) to the remote UE, and the relay UE should obtain the first device identifier of the remote UE. The relay UE can also obtain the S-TMSI and the IMSI of the remote UE at the same time, which is not limited in this application.

Step 12: The relay UE sends the second device identifier of the remote UE to the remote UE. In this application, the LID indicates the second device identifier of the remote UE.

It should be noted that a second device identifier uniquely identifies a remote UE in the plurality of remote UEs connected to the relay UE, and the value range of the second device identifier is smaller than the first device identifier.

In all remote UEs connected by one relay UE, each remote UE has a local identity LID for uniquely identifying itself in all remote UEs connected by the relay UE, that is, the relay UE can be unique through the LID. Identify a remote UE that is connected to itself.

The LID may be allocated by the relay UE or may be allocated by the base station, which is not limited in this application.

Optionally, the relaying UE sends the LID of the remote UE to the remote UE in the process of establishing a D2D connection with the remote UE, or relays the UE after the remote UE reports the UEID of the remote UE to the relay UE. When the response message is sent to the remote UE, the LID is sent to the remote UE through the response message.

For a wearable application scenario, the relay UE may be the user's smartphone, and the wearable device may be a smart watch, a smart bracelet, smart glasses, smart sports shoes, smart helmet, smart apparel, and other possible smart personal devices including Implantable smart device. Since the number of personal smart wearable devices is limited, the maximum number of remote UEs that a relay UE can access, for example, 7 or 15, can be specified, and the value range of the LID is 1 to 7 or 1 to 15.

Step 13: The relay UE receives the first paging message sent by the base station.

The first paging message is used to page the at least one remote UE that is connected to the relay UE, and the first paging message includes a first device identifier corresponding to the remote UE.

It is worth mentioning that after the remote UE establishes a D2D connection with the relay UE, the message sent by the network side to the remote UE is forwarded by the relay UE, and the network side may be remotely located after the remote UE enters the idle state. The paging message sent by the UE. The remote UE can connect to the network through the relay UE, and the remote UE can still negotiate the PO time point with the base station to which the relay UE is connected, and then the relay UE can receive the paging message sent by the base station to the remote UE at the PO time point. . Since the remote UE accesses the network through the relay UE, the PO time point between the remote UE and the base station can also directly use the PO time point negotiated by the relay UE and the base station, so that the relay UE can be in a PO time. The point receives the paging message sent by the base station to itself and the paging message of all the remote UEs connected to itself, avoiding waking up at multiple PO time points to receive their own paging message and connecting to each of their own remote UEs. Paging message, which is beneficial to save power consumption of the relay UE.

Step 14: The relay UE establishes a paging bit table after receiving the first paging message sent by the base station.

The relay UE first converts the UEID of the remote UE in the first paging message into an LID, and then generates a paging bit table according to the LID, and the length of the paging bit table is determined by the value of the valid maximum LID, such as LID. When the maximum value is 7, the paging bit table length may be 8 bits, wherein a bit corresponding to LID 0 may be used as a reserved bit, and when the LID maximum value is 15, the paging bit table length may be 16 bits, in the bit table. Each bit represents a remote UE, and the position of the bit represents the value of the LID. The value of the bit indicates whether the remote UE is paged. The first value indicates that the remote UE corresponding to the bit is paged. Taking the second value indicates that the remote UE corresponding to the bit is not paged. For example, taking "1" means being paged, and "0" means not being paged. According to the UEID converted in the paging message, the bit in the paging bit table corresponding to the LID is set to "1" to indicate that the bit is set, and the other bits in the paging bit table are set to "0" to indicate that the bit corresponds to the far The end UE is not paged.

Optionally, the first paging message may also be configured with core network domain information, that is, whether the paging information is from the circuit domain core network or the packet domain core network, so the relay UE also needs to establish a core network domain bit table. The length of the core domain bit table may be the same as the length of the paging bit table, where each bit corresponds to a remote UE, and the position of the bit represents the value of the LID, and the value of the bit represents the paging message of the remote UE. From the circuit domain core network or the packet domain core network, if the core network domain information indicates that the remote UE is paged by the circuit domain core network, the bit corresponding to the remote UE in the core network domain bit table is set to a third value. If the core domain information indicates that the remote UE is paged by the packet domain core network, the core is The bit corresponding to the remote UE in the domain bit table is set to a fourth value. For example, taking "1" means that the page is from the circuit domain core network, and "0" means that the page is coming from the packet domain core network. It is meaningless to take a value other than the bit corresponding to the LID corresponding to the UEID in the first paging message in the core domain bit table, because the remote UE corresponding to the bit is not paged.

Since the remote UE that is not paged does not need a bit to indicate which core domain the page is from, the core domain bit table does not need as many bits as the paging bit table, but only needs to be The number of remote UEs that are paged can be as many as the number of bits, so that the core domain bit table is relatively short, each of which indicates the core domain of a paged remote UE, and the meaning of the bit position It is the first few remote UEs that are paged. Assume that the number of "1" in the paging bit table is paged, and "0" means that it is not paged, then the number of "1" in the paging bit table is the effective number of bits in the core domain table. The sequence number k of one bit in the field bit table corresponds to the kth "1" of all "1"s in the paging bit table.

Figure 2a shows a schematic diagram of a specific paging bit table and core domain bit table. It is assumed that the paging bit table length is 16 bits, and the effective value of the LID is 1 to 15. Each bit in the paging bit table corresponds to one LID value. For example, the serial number value of the bit is used as the LID value. Of course, the bit number may be incremented by 1 as the LID value, or the bit number may be added to a set value. The starting value is taken as the LID value. A LID value of 0 may be used as a reserved value, that is, an LID of 0 does not specifically indicate a remote UE. Each bit in the paging bit table corresponds to a LID value, and each valid LID value corresponds to a remote UE. Of course, the remote UE corresponding to each bit in the paging bit table may not actually exist yet, that is, the LID value has not been assigned to a remote UE. Bits 1, 4, 5, 10, and 13 in the paging bit table shown in FIG. 2 are "1", indicating that the remote UE whose LID values are 1, 4, 5, 10, 13 are paged, and the like. The remote UE is not paged or the corresponding remote UE does not exist. After the paging bit table, it is an 8-bit core domain bit table. Since only 5 remote UEs are paged, the number of valid bits in the core domain bit table is only 5, that is, the sequence number is 0. 5 bits to 4, which respectively indicate the paging core domain of the far-end UE corresponding to 5 bits of the paging bit table corresponding to "1".

Specifically, considering that the probability that multiple remote UEs are simultaneously paged is small, the core domain bit table may be set to be shorter to obtain a compressed version of the core domain bit table, for example, at most 15 or 16 far In the case of a UE, the core domain bit table can be set to 8 bits, or further 4 bits can be used, and the paging bit table can also be compressed in some way to obtain a compressed version of the paging bit table, for example. Use 4 bits to indicate the LID value of the far-end UE that is being paged, followed by a local bit table of 4 or 8 bits to indicate the number of the far-end UE being paged, the number of each bit in the local bit table. Adding the starting LID value is the LID value of the true paged remote UE. If more remote UEs are actually being paged, the compressed version of the bit table format cannot indicate all the remote UEs being paged, and the relay UE may first forward the paging messages of the partially paged remote UEs. The remaining paging messages are forwarded again the next time to ensure that each paging message does not occupy too many bits. For example, the LID of the remote UE is valid from 1 to 15, and the LID of the remote UE being paged is 3, 7, 8, 9, and 10. The length of the paging table is set to 8 bits. The 4 bits identify the LID value of the far-end UE that is initially paged, which is 0011. The sequence number of each of the following 4 bits plus the LID value of the far-end UE that is initially paged is true. The LID value of the paged remote UE, that is, 4+3=7,5+3=8,6+3=9,7+3=10, as shown in FIG. 2b.

If the core domain of all the remote UEs is not related to the circuit domain, for example, a certain type of wearable device, the core paging information may not be involved in the first paging message forwarded by the relay UE, that is, the core domain does not exist. Bit table.

Step 15: The relay UE sends a discovery message, where the discovery message includes first bit table indication information indicating the paging bit table.

The first bit table indication information herein may directly include a paging bit table or a compressed version of the paging bit table.

The relay UE periodically sends a discovery message, so that the remote UE that is not connected to the relay UE can discover the relay. The UE, or the remote UE that has been connected to the relay UE, can continuously determine whether it is still within the signal coverage of the relay UE according to whether to detect the discovery message of the relay UE.

Since the discovery message carries the first bit table indication information of the remote UE indicating the paging bit table, the remote UE no longer needs to wake up to receive the paging message at the PO time point, which is beneficial to the remote UE to save power consumption. . In the case that the paging is frequent, the relay UE does not need to send both the discovery message and the paging message, and is also beneficial for the relay UE to save power.

Optionally, the discovery message further includes second bit table indication information indicating the core network domain bit table, where the second bit table information may include a compressed version of the core network domain bit table or the core network domain bit table.

Step 16: After receiving the discovery message, the remote UE parses the first bit indication information in the discovery message to determine whether it is paged.

The remote UE parses the first bit indication information in the discovery message to obtain a paging bit table. If the bit corresponding to its own LID in the paging bit table is set to a first value, for example, “1”, it indicates that it is being searched. Call, otherwise you are not being paged. If the remote UE finds that it is being paged by parsing the paging bit table, it may need to further parse the discovery message to obtain the core network domain indication information, and determine whether it is the circuit domain core network paging according to the corresponding bit in the core network domain bit table. Packet domain core network paging. For a method for parsing the core domain bit table, refer to step 14 for a description of the core domain bit table, and details are not described herein again.

Further, after transmitting the discovery message, the relay UE generates a second paging message, where the second paging message includes paging information for paging at least one remote UE; and the PO determined by the remote UE Transmitting the second paging message at a time point, so that the remote UE receives the second paging message at the PO time point after determining that the remote UE is paged according to the first bit table information And obtaining paging information of the remote UE. It should be noted that, if the remote UE determines that the remote UE is not paged according to the first bit table indication information, the second paging message does not need to be received, thereby achieving power saving. purpose. In addition, the second paging message may include more paging information related to the remote UE, for example, if the core network indication information is not included in the discovery message, optionally, the second paging message The core domain indication information may be carried in the remote UE to know which core domain is paged.

If the remote UE determines that it is not paged, it continues to sleep, otherwise it performs related operations after being paged, for example, notifying the core network to switch from the idle state to the active state, and performing other interactions with the core network, such as establishing a call. Complete the call, or receive the packet message sent by the network side server.

Through the foregoing process, the relay UE helps the remote UE to receive the paging message from the base station, and converts it into a paging bit table, occupies less bit resources, so that paging information of multiple remote UEs that are simultaneously present can be carried in the discovery. The message is transmitted, so that the remote UE can only determine whether it is paged by receiving the discovery message of the relay UE, and does not use the relay UE to forward the paging message at another PO time point, which is beneficial for the relay UE to save power. At the same time, the remote UE can determine whether it is paged by periodically waking up to receive the discovery message of the relay UE after connecting to the relay UE, without waking up to receive the paging message at another PO time point, which is beneficial to The remote UE saves power.
