Description

Communication method, communication device, electronic equipment and computer-readable storage medium

Technical Field

The present application relates to the field of communications technologies, and in particular, to a communication method, an apparatus, an electronic device, and a computer-readable storage medium.

Background

In the 4G network era, once a terminal accesses a network, a default bearer is established, so that the terminal is in an always-on state. However, the 5G independent networking (SA) network is different from the 4G network, for example, whether the terminal needs to establish a bearer when the terminal is powered on depends on the behavior of the terminal, and the terminal can directly return to an idle state or a connected state when the terminal is powered on. A first initialization MESSAGE (INITIAL UE MESSAGE) when the terminal establishes NG connection with the core network carries a Non-Access Stratum (NAS) MESSAGE. If there is no session in the NAS message, a FOR parameter is carried to the core network.

When the FOR parameter value is 0, indicating that no signaling exists subsequently, the core network issues a downlink NAS transport (NAS transport) message to establish NG connection, and the terminal successfully starts up and registers to return to an idle state; the case that the FOR parameter value is 1 indicates that there is a signaling subsequently, the core network sends an initial context setup request (initial context setup request) message, and the terminal is in a connected state after successful registration. When the terminal has data transmission, UPLINK data status (UPLINK data status) information is carried to the core network through an NAS message in an UPLINK NAS TRANSPORT (UPLINK NAS TRANSPORT) signaling process, so as to establish a PDU Session (PDU Session) for the UE.

For a terminal in a connected state, when the terminal is in a weak coverage area, for example: when the terminal moves to the edge of a service cell or moves to an area with relatively poor network signals, a Measurement result meeting preset conditions is reported to network side equipment, and the base station switches the terminal to a proper cell based on the received Measurement Report (MR) and the adjacent cell relation.

In the existing Protocol, no matter switching is performed through an NG interface or an Xn interface, a switching request message must carry a Protocol Data Unit Session identifier (PDU Session ID FOR short) field, so that after a connected-state terminal with the FOR parameter of 1 but not carrying the PDU Session reports an MR meeting a switching condition, a base station cannot trigger switching, which causes a call drop of the terminal in an original serving cell, and at this time, if the terminal is paged, there is a problem that paging is not in time.

The System may further include a core network portion, such as an Evolved Packet System (EPS), a 5G System (5GS), and the like.

The terms referred to in this application will first be introduced and explained:

the terminal device referred to in the embodiments of the present application may refer to a device providing voice and/or data connectivity to a user, a handheld device having a wireless connection function, or another processing device connected to a wireless modem. In different systems, the names of the terminal devices may be different, for example, in a 5G system, the terminal device may be called a User Equipment (UE). A wireless terminal device, which may be a mobile terminal device such as a mobile telephone (or "cellular" telephone) and a computer having a mobile terminal device, e.g., a portable, pocket, hand-held, computer-included or vehicle-mounted mobile device, may communicate with one or more Core Networks (CNs) via a Radio Access Network (RAN), and may exchange language and/or data with the Radio Access Network. Examples of such devices include Personal Communication Service (PCS) phones, cordless phones, Session Initiation Protocol (SIP) phones, Wireless Local Loop (WLL) stations, and Personal Digital Assistants (PDAs). The wireless terminal device may also be referred to as a system, a subscriber unit (subscriber unit), a subscriber station (subscriber station), a mobile station (mobile), a remote station (remote station), an access point (access point), a remote terminal device (remote terminal), an access terminal device (access terminal), a user terminal device (user terminal), a user agent (user agent), and a user device (user device), which are not limited in this embodiment of the present application.

The network side device according to the embodiment of the present application may be a base station, and the base station may include a plurality of cells for providing services for a terminal. A base station may also be called an access point, or may be a device in an access network that communicates over the air-interface, through one or more sectors, with wireless terminal devices, or by other names, depending on the particular application. The network-side device may be configured to exchange the received air frame with an Internet Protocol (IP) packet as a router between the wireless terminal device and the rest of the access network, where the rest of the access network may include an Internet Protocol (IP) communication network. The network side device may also coordinate attribute management for the air interface. For example, the network side device according to the embodiment of the present application may be a network side device (BTS) in a Global System for Mobile communications (GSM) or a Code Division Multiple Access (CDMA), may also be a network side device (NodeB) in a Wide-band Code Division Multiple Access (WCDMA), may also be an evolved Node B (eNB or e-NodeB) in a Long Term Evolution (LTE) System, a 5G Base Station (gNB) in a 5G network architecture (neighboring) System, may also be a Home evolved Node B (Home evolved Node B, NodeB), a relay Node (relay Node), a Home Base Station (femto), a pico Base Station (pico Base Station), and the like, and is not limited in the embodiments of the present application.

The MIMO transmission may be 2D-MIMO, 3D-MIMO, FD-MIMO, or massive-MIMO, or may be diversity transmission, precoding transmission, beamforming transmission, or the like, depending on the form and number of root antenna combinations.

A weak coverage area is an area where there is a signal but the signal strength cannot guarantee that the network will meet the requirements. The weak coverage problem is manifested as low call completing rate, high call dropping rate, poor user perception, etc.

When LTE is switched, UE needs to report measurement results (including Reference Signal Receiving Power (RSRP) and Reference Signal Receiving Quality (RSRQ), and reporting includes periodic reporting and event-triggered reporting. The periodic reporting is configured by the base station, and the UE directly reports the measurement result.

Event-triggered reporting is divided into events of the same-frequency system and events among different systems: the same-frequency switching reporting event comprises the following steps:

1. event a1, the serving cell measurement is better than the absolute threshold; this event can be used to turn off measurements between certain cells.

2. Event a2, the serving cell measurement is worse than an absolute threshold; this event may be used to turn on measurements between certain cells, since a handover or the like may occur after this event has occurred.

3. Event a3, the neighbor cell's measurement is better than the serving cell; this event occurrence can be used to decide whether the UE is handed over to a neighbor cell.

4. Event a4, the measurement result of the neighbor cell is better than the absolute threshold;

5. event a5, the serving cell measurement is worse than an absolute threshold and the neighbor cell measurement is better than an absolute threshold; this Event can also be used to support handover Event B1(Inter RAT neighbor tables from threshold): the quality of the adjacent cell of the different system is higher than a certain threshold, and when the event meeting the condition is reported, the source base station starts a different system switching request; similar to the 3C event of UMTS. Event B2(Serving belows word threshold1 and inter RAT neighbor tables threshold 2): indicating that the serving cell quality is below a certain threshold and the inter-system neighbor quality is above a certain threshold, similar to the 3A event of UMTS.

In the existing protocol, when a base station determines that the UE is switched based on the received MR meeting the condition, a PDU session field in a switching request message sent to the UE is sent. For the connected terminal device that does not establish the DRB, since the PDU session is not established, the handover request message does not have a PDU session field, and therefore the connected terminal device that does not establish the DRB cannot perform handover, which is specifically shown in fig. 1.

When the UE in the connected state does not establish a DRB, and the UE is located in a weak coverage area and reports a measurement report MR meeting requirements, for example, an MR reporting an a3 event, the base station does not perform any processing after receiving the MR, thereby causing the following problems:

1) increasing the probability of call drop of the UE in an environment with poor coverage;

2) the probability of paging unreachable is increased;

3) the terminal equipment reports the measurement event meeting the conditions, and cannot be processed by the network side, so that the terminal equipment is not beneficial to saving electricity;

4) affecting network performance metrics.

In view of the above, the present application provides a communication method, an apparatus, an electronic device, and a computer-readable storage medium, which are intended to solve the above technical problems in the prior art.

Specifically, the embodiments of the present application provide a communication method, which can solve the following problems: in a 5G SA network, when a terminal device moves to a weak coverage area, for example: when the terminal moves to the edge of the serving cell or the environment with relatively poor network signals, the network side can normally process the connected terminal device without establishing a Data Radio Bearer (DRB), that is, the connected terminal device without establishing a corresponding PDU Session (PDU Session), so as to avoid the problem that the terminal device is in the original serving cell and the call drop (is always dragged to be dead) due to poor signals, and the problem that the paging is not in time can occur if the terminal device is paged at the moment.

The following describes the technical solutions of the present application and how to solve the above technical problems with specific embodiments. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments. Embodiments of the present application will be described below with reference to the accompanying drawings.

In an embodiment of the present application, a communication method is provided, as shown in fig. 2, where the method 10 includes:

101. when a measurement report meeting a preset condition is acquired, determining an instruction sent to terminal equipment according to the type of the measurement report, wherein the terminal equipment is in a connection state and does not establish a data radio bearer, and the instruction is a switching instruction or a releasing instruction;

102. and sending the instruction to the terminal equipment.

Specifically, in this embodiment, the types of measurement reports include: if the measurement report meeting the preset condition is the measurement report of the A3824 event, sending a switching instruction to the terminal equipment; and if the measurement report meeting the preset condition is the measurement report of the A2 event, sending a release instruction to the terminal equipment.

It should be noted that, in order to ensure the user experience, only when the measurement report of the A3 event is not acquired, the UE is determined to be released based on the measurement report of the a2 event. That is to say, when the measurement report MR of the A3 event meeting the preset threshold can be acquired, the UE is switched to the neighboring cell based on the MR, so as to ensure that the UE does not drop the call, and only when the measurement report of the A3 event is not acquired, the UE is released based on the acquired measurement report MR of the a2 event meeting the preset threshold.

The method in the above embodiment is described in further detail with reference to fig. 3.

When the UE in the connected state, which does not carry the PDU Session, is located in a weak coverage area and reports a measurement report MR meeting the requirements, for example, the MR reporting the a3 event, the base station determines and sends a handover instruction to the UE after receiving the MR, so as to handover a serving cell of the UE.

Specifically, the handover command is used to instruct the UE to handover the serving cell based on the NG interface or the Xn interface.

That is to say, in the scheme of the embodiment of the present application, the base station does not determine whether the UE carries the PDU Session information any more, and normally sends the handover command to complete the handover process, thereby avoiding the problem that the UE is always dragged to death in the original serving cell due to a poor signal.

It should be understood that, in this embodiment, the specific procedure of the UE switching the serving cell based on the NG interface or the Xn interface may be implemented by using the prior art, and those skilled in the art can easily know the related prior art, and for brevity of description, the detailed description is omitted here.

When the UE which is in the connected state and does not carry the PDU Session is located in a weak coverage area and does not report the MR of the A3 event meeting the requirements, the UE is obtained to report the MR of the A2 event meeting the preset threshold, and the base station determines and sends a release instruction to the UE after receiving the MR so as to release the UE to the idle state.

That is to say, in the scheme of the embodiment of the present application, when the base station receives an a2 measurement report that the UE that does not carry a PDU Session reports that meets the preset condition, it indicates that the serving cell signal quality is poor, and the base station actively initiates a UE release process.

The above embodiment is based on the existing protocol, and optimizes the base station side processing, so that the UE in the connected state not carrying the PDU Session can perform normal handover or return to the idle state through normal release of the network when the conditions are met, thereby avoiding the problem that the UE in the weak coverage area is dragged to death and paging is not reachable due to the normal handover.

It should be noted that, in the foregoing embodiment, the specific process of determining whether the UE is in the weak coverage area may be implemented by using the prior art, and a person skilled in the art can easily know the related prior art, and for brevity of description, details are not described here again.

A communication method provided in the following embodiments optimizes core network side processing based on an existing protocol, where a specific process is shown in fig. 4 and 5, and as shown in fig. 4, the method 20 includes:

201. and after the terminal equipment is successfully registered, sending a release instruction to the terminal equipment so as to release the terminal equipment to an idle state, wherein the terminal equipment is in a connected state and does not establish a data radio bearer.

That is to say, as shown in fig. 5, when the UE in the connected state that does not carry the PDU Session completes registration, the core network device actively sends a release instruction to the UE to release the UE to the idle state.

For the case of the unregistered completion, the processing is the same as that in the prior art, and for the sake of brevity of description, the details are not repeated here.

In summary, in the communication method provided in the embodiment of the present application, when a base station performs a handover request, it is not determined whether a DRB is established by a UE, that is, whether a PDU Session exists; switching can be carried out when the measurement report reported by the connected state terminal not carrying the PDU Session meets the condition;

when the UE which does not carry the PDU Session is successfully registered, the core network can actively trigger the UE to release; when the base station receives an a2 event measurement report reported by a terminal which does not establish a DRB, the base station may actively trigger the UE to release.

Therefore, the communication method provided in the foregoing embodiment increases the number of idle terminals in the network to a certain extent, reduces the possibility of the number of inactive (inactive) terminals, and can also improve the paging reachable rate of the UE, thereby facilitating the network index improvement and optimizing the utilization rate of the air interface message.
