It should be apparent that the described embodiments are only some of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application. "and/or" in various embodiments of the present specification means at least one of front and rear.
It should be understood that the technical solutions of the embodiments of the present invention may be applied to various communication systems, for example: a Long Term Evolution (LTE) System, an LTE Frequency Division Duplex (FDD) System, an LTE Time Division Duplex (TDD) System, a Universal Mobile Telecommunications System (UMTS) or Worldwide Interoperability for Microwave Access (WiMAX) communication System, a 5G System, a New Radio (NR) System, or a subsequent Evolution communication System.
In the embodiment of the present invention, the Terminal device may include, but is not limited to, a Mobile Station (MS), a Mobile Terminal (Mobile Terminal), a Mobile phone (Mobile Telephone), a User Equipment (UE), a handset (handset), a portable device (portable Equipment), a vehicle (vehicle), etc., and the Terminal device may communicate with one or more core networks through a Radio Access Network (RAN), for example, the Terminal device may be a Mobile phone (or referred to as a "cellular" phone), a computer with a wireless communication function, and the Terminal device may also be a portable, pocket, handheld, computer-embedded, or vehicle-mounted Mobile apparatus.
In the embodiment of the present invention, the network device is a device deployed in a radio access network to provide a wireless communication function for a terminal device. The network device may be a base station, and the base station may include various macro base stations, micro base stations, relay stations, access points, and the like. In systems employing different radio access technologies, the names of devices having the function of a base station may differ. For example, in an LTE network, called an Evolved node B (eNB or eNodeB), in a third Generation (3G) network, called a node B (node B), or a network device in a later Evolved communication system, etc., although the words are not limiting.
As shown in fig. 1, an embodiment of the present invention provides a method 100 for processing a protocol data unit session, which may be performed by a UE, in other words, the method may be performed by software or hardware installed in the UE, and the method includes the following steps:
s112: and acquiring the maximum number of Protocol Data Unit (PDU) sessions supported by the network.
The network may be a PLMN, that is, this step may be to obtain the maximum number of PDU sessions supported by the PLMN, N1.
S114: and processing the PDU session according to the maximum number of the PDU sessions supported by the network.
The UE may process the PDU session, e.g., establish or release the PDU session, according to the maximum number of PDU sessions supported by the network N1.
Therefore, according to the method for processing the protocol data unit session provided by the embodiment of the invention, the maximum number of the Protocol Data Unit (PDU) sessions supported by the network is obtained, and the PDU session is processed according to the maximum number of the PDU sessions supported by the network, so that the UE can acquire the maximum number of the PDU sessions supported by the network without trying to establish the PDU session for many times, and the PDU session is processed according to the maximum number of the PDU sessions supported by the network, thereby avoiding the rejection of the request for establishing the PDU session by the network, and further improving the efficiency of establishing the upper layer service.
As shown in fig. 2, an embodiment of the present invention provides a method 200 for processing a protocol data unit session, which may be performed by a UE, in other words, the method may be performed by software or hardware installed in the UE, and the method includes the following steps:
s212: and acquiring the maximum number of Protocol Data Unit (PDU) sessions supported by the network.
The network may be a PLMN, that is, this step may be to obtain the maximum number of PDU sessions supported by the PLMN, N1.
In one implementation, the maximum number of PDU sessions supported by the network may be pre-configured in the UE. For example, as part of the subscription data, operator a may pre-configure the parameters of network a in the UE, including the maximum number of PDU sessions supported by the PLMN N1.
In another implementation, the maximum number of PDU sessions supported by the network may also be received from the network device, that is, the network device sends the maximum number of PDU sessions supported by the PLMN N1 to the UE.
In this case, the maximum number N1 of PDU sessions supported by the network may be included in a mobility management message or a PDU session message or a Radio Resource Control (RRC) message sent by the network device.
The mobility management message may include: a registration accept message or a configuration update message. For example, an Information Element (IE) may be added to the existing 5G registration accept message to indicate the maximum number of PDU sessions supported by the PLMN, N1. In particular, the UE may send a registration request message to the network device, which in response sends a registration accept message to the UE containing the maximum number of PDU sessions supported by the PLMN N1.
In one implementation, for a roaming scenario, the maximum number of PDU sessions is the lesser of the maximum number of PDU sessions supported by the roaming network and the maximum number of PDU sessions supported by the home network.
For roaming scenarios, the maximum number of PDU sessions may also be preconfigured in the UE, e.g., operator a may subscribe to two other roaming-capable operators B/C, and thus operator a may provision parameters of 3 networks A, B, C within the UE, including the maximum number of PDU sessions supported by network A, B, C. In this way, when the UE is in the network A, B, C, the maximum number of PDU sessions supported by the network corresponding to each network is read from the UE and compared.
Of course, for the roaming scenario, the maximum number of PDU sessions may also be received from the network device.
S214: and processing the PDU session according to the maximum number of the PDU sessions supported by the network.
In one implementation, the PDU session may be processed according to the maximum number of PDU sessions supported by the network, N1, and the maximum number of protocol-allowed PDU sessions (the maximum number of PDU session allowed by the protocol), N2.
In another implementation, the PDU session may also be processed according to the maximum number of PDU sessions supported by the network N1, the maximum number of protocol-allowed PDU sessions N2, and the maximum number of UE's implementation-specific maximum number of PDU sessions (PDU sessions) N3.
Therefore, according to the method for processing the protocol data unit session provided by the embodiment of the invention, the maximum number of the Protocol Data Unit (PDU) sessions supported by the network is obtained, and the PDU session is processed according to the maximum number of the PDU sessions supported by the network, so that the UE can acquire the maximum number of the PDU sessions supported by the network without establishing the PDU session for many times, the request for establishing the PDU session is prevented from being rejected by the network, and the efficiency of establishing an upper layer service is improved.
As shown in fig. 3, an embodiment of the present invention provides a method 300 for processing a protocol data unit session, which may be performed by a UE, in other words, the method may be performed by software or hardware installed in the UE, and the method includes the following steps:
s312: and acquiring the maximum number of Protocol Data Unit (PDU) sessions supported by the network.
The step may be similar to the steps S112 and S212, and is not described herein again.
S314: and determining the smaller of the maximum number of the PDU sessions supported by the network and the maximum number of the PDU sessions allowed by the protocol as the maximum number of the PDU sessions which can be established by the UE in the network.
The smaller of The maximum number of PDU sessions supported by The network N1 and The maximum number of PDU sessions allowed by The protocol N2 is determined as The maximum number of PDU sessions (The maximum number of PDU sessions of UE can be established in The network) N. In other words, N is the smaller of N1 and N2.
When an upper layer service requests to establish a new PDU session, the UE compares the values of n 'and n and judges whether the number n' of the PDU sessions established by the UE in the network reaches the maximum number of the PDU sessions which can be established by the UE in the network. Namely, whether n' is more than or equal to n is judged.
S316: and under the condition that the number of the PDU sessions established by the UE in the network reaches the maximum number of the PDU sessions which can be established by the UE in the network, releasing at least one PDU session in the established PDU sessions and sending a PDU session establishment request to the network equipment.
I.e. in case n' ≧ n, the UE may release at least one established PDU session and establish a new PDU session.
In another implementation, the step may also include: and under the condition that the number of the PDU sessions established by the UE in the network reaches the maximum number of the PDU sessions which can be established by the UE in the network, giving up sending the PDU session establishment request to the network equipment.
That is, under the condition that n' ≧ n, the UE may not release the established PDU session, maintain the established PDU session, and also not establish a new PDU session.
S318: and under the condition that the number of the PDU sessions established by the UE in the network does not reach the maximum number of the PDU sessions which can be established by the UE in the network, sending a PDU session establishment request to the network equipment so as to establish the PDU session.
In the case where n' < n, the UE sends a PDU session setup request to the network device, thereby establishing a new PDU session.
Therefore, the method for processing the protocol data unit session provided by the embodiment of the invention can enable the UE to acquire the maximum number of the PDU sessions supported by the network without establishing the PDU sessions for many times by acquiring the maximum number of the protocol data unit PDU sessions supported by the network and processing the PDU sessions according to the maximum number of the PDU sessions supported by the network, thereby avoiding the rejection of the request for establishing the PDU sessions by the network, reducing the network signaling flow, saving the signaling resources, improving the service response speed and improving the efficiency for establishing the upper service.
As shown in fig. 4, an embodiment of the present invention provides a method 400 for processing a protocol data unit session, which may be performed by a UE, in other words, the method may be performed by software or hardware installed in the UE, and the method includes the following steps:
s412: and acquiring the maximum number of Protocol Data Unit (PDU) sessions supported by the network.
The step may be similar to the steps S112 and S212, and is not described herein again.
S414: determining a minimum of the maximum number of PDU sessions supported by the network, the maximum number of protocol-allowed PDU sessions, and the maximum number of PDU sessions specifically implemented by the UE as the maximum number of PDU sessions that the UE can establish in the network.
The UE determines the minimum of the maximum number N1 of PDU sessions supported by the PLMN, the maximum number N2 of protocol-allowed PDU sessions and the maximum number N3 of UE-specific implemented PDU sessions as the maximum number N of PDU sessions that the UE can establish in the PLMN. In other words, N takes the minimum of N1, N2, and N3.
When an upper layer service requests to establish a new PDU session, the UE compares the values of n 'and n and judges whether the number n' of the PDU sessions established by the UE in the network reaches the maximum number of the PDU sessions which can be established by the UE in the network. Namely, whether n' is more than or equal to n is judged.
S416: and under the condition that the number of the PDU sessions established by the UE in the network reaches the maximum number of the PDU sessions which can be established by the UE in the network, releasing at least one PDU session in the established PDU sessions and sending a PDU session establishment request to the network equipment.
I.e. in case n' ≧ n, the UE may release at least one established PDU session and establish a new PDU session.
In another implementation, the step may also include: and under the condition that the number of the PDU sessions established by the UE in the network reaches the maximum number of the PDU sessions which can be established by the UE in the network, giving up sending the PDU session establishment request to the network equipment.
That is, under the condition that n' ≧ n, the UE may also keep the existing established PDU session without releasing the established PDU session, and does not establish a new PDU session.
S418: and under the condition that the number of the PDU sessions established by the UE in the network does not reach the maximum number of the PDU sessions which can be established by the UE in the network, sending a PDU session establishment request to the network equipment so as to establish the PDU session.
In the case where n' < n, the UE sends a PDU session setup request to the network device, thereby establishing a new PDU session.
Therefore, according to the method for processing the protocol data unit session provided by the embodiment of the invention, the maximum number of the protocol data unit PDU sessions supported by the network is obtained, and the PDU session is processed according to the maximum number of the PDU sessions supported by the network, so that the UE can acquire the maximum number of the PDU sessions supported by the network without establishing the PDU session for many times, the rejection of the request for establishing the PDU session by the network is avoided, the network signaling flow can be reduced, the signaling resource is saved, the service response speed is increased, and the efficiency for establishing the upper service is improved.
As shown in fig. 5, an embodiment of the present invention provides a method 500 for processing a protocol data unit session, which may be performed by a network device and a UE, in other words, the method may be performed by software or hardware installed in the network device and the UE, and the method includes the following steps:
s522: the network equipment sends the maximum number of PDU sessions supported by the network to the UE.
The network equipment sends the maximum number N1 of PDU sessions supported by the PLMN to the UE, so that the UE can acquire the maximum number of PDU sessions supported by the network.
S512: and the UE receives the maximum number of the PDU sessions supported by the network and sent by the network equipment.
The UE receives the maximum number of PDU sessions supported by the PLMN N1.
S514: and the UE processes the PDU session according to the maximum number of the PDU sessions supported by the network.
The specific steps may be similar to those in embodiments 100-400, and are not described herein again.
S524: the network equipment sends the updated maximum number of network-supported PDU sessions N1' to the UE.
In one implementation, when the maximum number of PDU sessions supported by the network N1 changes, the updated maximum number of PDU sessions supported by the PLMN N1' may be sent to the UE through other core network messages, for example, may be included in a configuration update message sent by the network device. Of course, the network device may also send the updated maximum number of PDU sessions N1' supported by the PLMN through other commands or messages.
S516: receiving the updated maximum number of the PDU sessions supported by the network and sent by the network equipment, and processing the PDU sessions according to the updated maximum number of the PDU sessions supported by the network.
In one implementation, the UE may determine the maximum number N of PDU sessions that the UE can establish in the network according to the updated maximum number N1' of PDU sessions supported by the PLMN, and the maximum number N2 of protocol-allowed PDU sessions.
In another implementation, the UE may determine the maximum number N of PDU sessions that the UE can establish in the network according to the updated maximum number N1' of PDU sessions supported by the PLMN, the maximum number N2 of protocol-allowed PDU sessions, and the maximum number N3 of UE-specific implemented PDU sessions.
And, in one implementation, in case that the number n' of PDU sessions that the UE has established in the network has reached the maximum number n of PDU sessions that the UE can establish in the network, the UE may release at least one of the established PDU sessions and send a PDU session establishment request to the network device, thereby establishing a new PDU session.
In one implementation, in a case that the number n' of PDU sessions that the UE has established in the network has reached the maximum number n of PDU sessions that the UE can establish in the network, the UE may forego sending a PDU session establishment request to the network device, i.e. not releasing an established PDU session nor establishing a new PDU session.
In one implementation, in a case that the number n' of PDU sessions that the UE has established in the network does not reach the maximum number n of PDU sessions that the UE can establish in the network, the UE may send a PDU session establishment request to the network device, thereby establishing the PDU session.
The specific steps may be similar to those in embodiments 100-400, and are not described herein again.
Therefore, in the method for processing a protocol data unit session provided by the embodiment of the present invention, the maximum number of PDU sessions supported by the network is updated by receiving the PDU sessions sent by the network device; and processing the PDU session according to the updated maximum number of the PDU sessions supported by the network, so that the network signaling flow can be reduced, the signaling resource can be saved, the service response speed can be increased, and the efficiency of establishing an upper layer service can be increased.
