The present disclosure relates to a field of communication technology, and more particularly, to a method for establishing a shared session, an apparatus for establishing a shared session and a communication device.
At present, a mobile network formulates a related mobility management procedure, a related session management procedure, and other characteristics mainly for a single user equipment (UE). At the same time, in terms of UE management and UE resource allocation, the mobile network also performs related operations for a single UE.
With the rapid development of the mobile network, an era of Internet of Everything is coming. Limited by the capability of a single device, a single UE may not be capable of completing the complex tasks and mission. In this case, multiple UEs may be needed to cooperate closely to complete the complex tasks and mission.
However, current standardized protocol can only establish a session for a single UE. Therefore, how to achieve a solution of multiple UEs sharing a session remains a problem to be solved.
Embodiments of a first aspect of the disclosure provide a method for establishing a shared session, performed by a session management function (SMF). The method includes: receiving a protocol data unit (PDU) session establishment request from a user equipment (UE), in which the PDU session establishment request includes a multimodal service identifier; determining a corresponding PDU session based on the PDU session establishment request; and binding the PDU session with a shared N4 session corresponding to the multimodal service identifier, so that a plurality of PDU sessions corresponding to the multimodal service identifier share the shared N4 session.
Embodiments of a second aspect of the disclosure provide another method for establishing a shared session, performed by a user equipment (UE). The method includes: sending a protocol data unit (PDU) session establishment request to a session management function (SMF), in which the PDU session establishment request includes a multimodal service identifier, and the SMF binds a PDU session corresponding to the PDU session establishment request with a shared N4 session corresponding to the multimodal service identifier, and a plurality of PDU sessions corresponding to the multimodal service identifier share the shared N4 session.
Embodiments of a third aspect of the disclosure provide another method for establishing a shared session, performed by an access network device. The method includes: receiving a protocol data unit (PDU) session establishment request from a user equipment (UE), in which the PDU session establishment request includes a multimodal service identifier; and sending the PDU session establishment request to an access and mobility management function (AMF), and sending the PDU session establishment request to a session management function (SMF) through the AMF, in which the SMF binds a PDU session corresponding to the PDU session establishment request with a shared N4 session corresponding to the multimodal service identifier, and a plurality of PDU sessions corresponding to the multimodal service identifier share the shared N4 session.
Embodiments of a fourth aspect of the disclosure provide another method for establishing a shared session, performed by an access and mobility management function (AMF). The method includes: receiving a protocol data unit (PDU) session establishment request from a user equipment (UE), in which the PDU session establishment request includes a multimodal service identifier; determining a target session management function (SMF) based on the multimodal service identifier; and sending the PDU session establishment request to the target SMF.
Additional aspects and advantages of embodiments of present disclosure will be given in part in the following descriptions, become apparent in part from the following descriptions, or be learned from the practice of the embodiments of the present disclosure.
These and other aspects and advantages of embodiments of the present disclosure will become apparent and more readily appreciated from the following descriptions made with reference to the drawings, in which:
provided by an embodiment of the present disclosure;
Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. The following description refers to the accompanying drawings in which the same numbers in different drawings represent the same or similar elements unless otherwise represented. The implementations set forth in the following description of exemplary embodiments do not represent all implementations consistent with the disclosure. Instead, they are merely examples of apparatuses and methods consistent with aspects related to the disclosure as recited in the appended claims.
The terms used in the disclosure are only for the purpose of describing specific embodiments, and are not intended to limit the disclosure. The singular forms of “a” and “the” used in the disclosure and appended claims are also intended to include plural forms, unless the context clearly indicates other meanings. It should also be understood that the term “and/or” as used herein refers to and includes any or all possible combinations of one or more associated listed items.
It should be understood that although the terms “first”, “second”, and “third” may be used in this disclosure to describe various information, the information should not be limited to these terms. These terms are only used to distinguish the same type of information from each other. For example, without departing from the scope of the disclosure, the first information may also be referred to as the second information, and similarly, the second information may also be referred to as the first information. Depending on the context, the term “if” as used herein can be interpreted as “when”, “while” or “in response to determining”.
Embodiments of the present disclosure are described in detail below, examples of which are illustrated in the accompanying drawings. The same or similar elements are denoted by like reference numerals throughout the descriptions. The embodiments described herein with reference to drawings are explanatory, illustrative, and used to generally understand the present disclosure. The embodiments shall not be construed to limit the present disclosure.
With the rapid development of a mobile network, the era of Internet of Everything is coming. Limited by a capability of a single device, a single UE may not complete a complex requirement and mission (also referred to as service). In this case, multiple UEs may need to cooperate closely to complete the complex requirement and mission. For example, in industrial scenarios, multiple different types of robots, monitors, and controllers need to be closely cooperate to complete a mission of the production line. For another example, in a future smart stage, multiple cameras, microphones, background processing servers, consoles and speakers may need to cooperate closely to present a perfect stage effect.
However, the current standardized protocol establishes a session only for a single UE. Therefore, how to realize a solution of multiple UEs sharing a session is a problem to be solved.
When the UE establishes a protocol data unit (PDU) session, for the PDU session, a session management function (SMF) and a user plane function (UPF) will establish N4 session context, respectively. The SMF and the UPF communicate through an N4 interface, and data transmitted through the communication between the SMF and the UPF can be included in a structure of the N4 session. The SMF may also store a relationship between the N4 session and the PDU session. For one PDU session, one N4 session is established.
The SMF can store UE session context and the N4 session context. The N4 session context can include at least one of the following information:
As an example, attribute information in the List of PDRs may be as shown in Table 1.
It can be understood that each element and each correspondence in Table 1 exist independently. These elements and correspondences are exemplarily listed in the same table, but it does not indicate that all elements, correspondence must exist simultaneously as shown in Table 1. The value of each element and each correspondence do not depend on any other element value or correspondence in Table 1. Therefore, those skilled in the art can understand that the value of each element in Table 1 or each correspondence in Table 1 may be considered as an independent embodiment.
In view of the above existing problems, the disclosure provides a method for establishing a shared session, an apparatus for establishing a shared session and a communication device.
As illustrated in
The UE may be a device that provides voice and/or data connectivity to a user, a handheld device with a wireless connection function, or other processing devices connected to a wireless modem, and the like. In different systems, the name of the UE may be different. The wireless UE can communicate with one or more core networks (CNs) via a radio access network (RAN), and the wireless UE can be a mobile terminal device, such as a mobile phone (or called “cellular” telephone) and a computer with a mobile terminal, such as a portable, pocket, hand-held, computer built-in or vehicle-mounted mobile device, which may exchange voice and/or data with the radio access network.
For example, the UE may be a personal communication service (PCS) phone, a cordless phone, a session initiated protocol (SIP) phone, a wireless local loop (WLL) station, a personal digital assistant (PDA) and other devices. The wireless UE may also be called a system, a subscriber unit, a subscriber station, a mobile station, a mobile, a remote station, an access point, a remote terminal, an access terminal, a user terminal, a user agent, and a user device, which is not limited in embodiments of the disclosure.
The access network device may be a base station, for example. The base station may include multiple cells providing services for UEs. Depending on the specific application, each cell can contain multiple TRPs (Transmission Reception Points or Transmit Receive Points), each TRP can contain one or more antenna panels. Or, the base station can be a device in the access network that communicates with a wireless terminal through one or more sectors on an air interface, or other names. For example, the base station involved in the embodiments of the disclosure may be a base transceiver station (BTS) in a global system for mobile communications (GSM) or code division multiple access (CDMA), it can also be a base station (NodeB) in wide-band code division multiple access (WCDMA), and it can also be an evolutional Node B (referred to as eNB or e-NodeB) in a long term evolution (LTE) system, a 5G base station (referred to as gNB) in the 5G network architecture (next generation system), or can also be a home evolved Node B (HeNB), a relay node, a femto, a pico, etc., which is not limited in embodiments of the disclosure.
In the embodiments of the disclosure, a multimodal service refers to a service or mission that requires cooperation of multiple UEs, that is, multiple UEs perform the same multimodal service.
In the embodiment of the disclosure, the UE may send the PDU session establishment request to the SMF through the access network device. The PDU session establishment request may include the multimodal service identifier, and the multimodal service identifier may be configured to identify a same multimodal service, or, the multimodal service identifier may be configured to identify multiple UEs sharing a PDU session.
Alternatively, the UE may send the PDU session establishment request to an access and mobility management function (AMF) through the access network device, and send the PDU session establishment request to the SMF through the AMF.
In a possible implementation of the embodiment of the disclosure, the AMF may send the PDU session establishment request to the SMF responsible for the above multimodal service.
In another possible implementation of the embodiment of the disclosure, the AMF may send the PDU session establishment request to the SMF to which multiple PDU sessions corresponding to the multimodal service identifier belong.
In the embodiment of the disclosure, after receiving the PDU session establishment request, the SMF may determine the PDU session corresponding to the PDU session establishment request.
In the embodiment of the disclosure, the shared N4 session corresponding to the multimodal service identifier refers to an N4 session corresponding to a PDU session established by the UE that performs a multimodal service corresponding to the multimodal service identifier.
In the embodiment of the disclosure, the SMF can bind the PDU session determined in step 102 with the shared N4 session corresponding to the multimodal service identifier, so that multiple PDU sessions corresponding to the multimodal service identifier can share the shared N4 session.
With the method for establishing a shared session according to the embodiment of the disclosure, the SMF receives the PDU session establishment request from the UE through the access network device, in which the PDU session establishment request includes the multimodal service identifier. The SMF determines the corresponding PDU session according to the PDU session establishment request, and binds the PDU session with the shared N4 session corresponding to the multimodal service identifier, so that multiple PDU sessions corresponding to the multimodal service identifier share the above-mentioned shared N4 session. In this way, when multiple UEs cooperate to complete the multimode service, multiple PDU sessions can share the same shared N4 session, that is, the multiple UEs can use the same shared N4 session, which can reduce network resource consumption.
The embodiments of the disclosure further provide another method for establishing a shared session.
As illustrated in
In the embodiment of the disclosure, step 201 may be implemented in any way described in the embodiments of the disclosure, which is not limited in the embodiment of the disclosure, and will not be repeated here.
In any embodiment of the disclosure, the multimodal service identifier may include one or more of a mission identifier (mission ID, also referred to as service ID), a shared session identifier (for example, the shared session identifier may be a shared PDU session ID) and a group identifier (group ID).
In the embodiment of the disclosure, after receiving the PDU session establishment request, the SMF can determine, according to the multimodal service identifier, whether another UE that performs a multimodal service corresponding to the multimodal service identifier has established a PDU session. In the case that another UE performing the above-mentioned multimodal service has established the PDU session, that is, there are the PDU session established for the multimodal service identifier, in this case, step 203 may be executed. In the case that no other UE performing the above-mentioned multimodal service establishes the PDU session, that is, there is no PDU session established for the multimodal service identifier, in this case, step 204 may be executed.
In the embodiment of the disclosure, in the case that another UE performing the above multimodal service has established the PDU session, the SMF can establish the PDU session corresponding to the UE that initiates the PDU session establishment request, or join the PDU session established by another UE performing the above multimodal service. A shared N4 session corresponding to the multimodal service identifier may be an N4 session corresponding to the PDU session established by the UE performing the above multimodal service.
In the embodiment of the disclosure, in the case that no other UE performing the above multimodal service establishes the PDU session, the SMF can establish the PDU session corresponding to the UE that initiates the PDU session establishment request and establish the N4 session corresponding to the PDU session. In this case, the N4 session may be the shared N4 session corresponding to the multimodal service identifier.
As an example, the SMF can determine whether another UE performing the multimodal service corresponding to the multimodal service identifier has established the PDU session according to the multimodal service identifier, such as mission ID or group ID, and if so, the SMF can establish a new PDU session and update N4 session context, or join the existing PDU session and update the N4 session context, and if no, the SMF can establish a new PDU session and new N4 session context.
In the embodiment of the disclosure, step 205 may be implemented in any way described in the embodiments of the disclosure, which is not limited in the embodiment of the disclosure, and will not be repeated here.
With the method for establishing a shared session according to the embodiment of the disclosure, the SMF receives the PDU session establishment request from the UE through the access network device, in which the PDU session establishment request includes the multimodal service identifier. The SMF determines the corresponding PDU session according to the PDU session establishment request, and binds the PDU session with the shared N4 session corresponding to the multimodal service identifier, so that multiple PDU sessions corresponding to the multimodal service identifier share the above-mentioned shared N4 session. In this way, when multiple UEs cooperate to complete the multimode service, multiple PDU sessions can share the same shared N4 session, that is, the multiple UEs can use the same shared N4 session, which can reduce network resource consumption.

In the embodiment of the disclosure, the SMF may send the updated QoS parameter to the UE and the access network device. The updated QoS parameter may be a part of the updated N4 context parameter. Correspondingly, after receiving the updated QoS parameter, the UE may determine a service level and configuration corresponding to itself according to the updated QoS parameter, so that a corresponding flow control measure can be taken. Correspondingly, after receiving the updated QoS parameter, the access network device can provide corresponding services for the UE according to the updated QoS parameter.
In a possible implementation of the embodiment of the disclosure, the updated QOS parameter may include updated QoS profile information and updated QoS rules, and the SMF may send the updated QoS profile information to the access network device and send the updated QoS rules information to the UE.
