Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, 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 invention.
An embodiment of the present invention provides a service establishment method, where the method is applied to a terminal in an idle state for radio resource control and connection management, as shown in fig. 1 and 6, and the method includes:
step 1100, responding to a data transmission demand, and sending a radio resource control configuration request to a network side; so that the network side acquires the context setting request from the core network and allocates air interface resources for the terminal;
in some embodiments, the terminal is a terminal already registered to the network, and the radio resource control and connection management of the terminal are both in an IDLE state in order to save resources when there is no data transmission, for example, the terminal enters a state of RRC _ IDLE, CM _ IDLE. At this time, the terminal and the network side do not need to store the terminal context data related to the service. The network side can carry some encryption or security completion algorithms used by the recommended terminal in the radio resource control release message for the terminal to subsequently access the network side for use. When the terminal has uplink data to be transmitted or sends a paging message to the terminal because the network side has downlink data to be transmitted, a non-access stratum of the terminal triggers a service request, and radio resource control of the terminal sends a radio resource control configuration request RrcConfigurationRequest on an air interface. After receiving the radio resource control configuration Request RrcConfigurationRequest, the network side sends a Message Initial UE Message of an initialization terminal to the core network, and after receiving the Message Initial UE Message of the initialization terminal, the core network sends an initialization Context Setup Request Initial Context Setup Request to the network side.
As an optional implementation manner, the sending the radio resource control configuration request to the network side includes: and carrying more than one complete security and encryption algorithm, the content of the service request, the terminal identity information and the selected network identity information in the radio resource control configuration request so that the network side stores the complete security and encryption algorithm and the terminal identity information and sends the service request content and the selected network identity information to a core network. In some embodiments, the rrc configuration request carries one or more of the security and encryption algorithms desired by the terminal, the service request content, the terminal Identity information ue-Identity, and the selected network Identity information selected plmn-Identity. After receiving the Message, the network side stores the information such as the complete security and encryption algorithm expected by the terminal, the terminal Identity information UE-Identity and the like, and simultaneously sends the service request content service request, the selected network Identity information UE-Identity and the like to the core network through initializing the Message Initial UE Message of the terminal. In other embodiments, the message content carried by the rrc configuration request may not include the security completion and encryption algorithm.
Step 1200, receiving radio resource control configuration information sent by a network side, establishing a connection for carrying control plane signaling data or a connection for carrying user plane data according to the radio resource control configuration information, and activating access stratum security verification;
in some embodiments, after receiving the initial Context Setup Request, the network side allocates air interface resources and issues radio resource control configuration information RrcConfiguration to the terminal, where the radio resource control configuration information RrcConfiguration includes configuration information such as control plane signaling data SRB, user plane data DRB, medium access control layer MAC, physical configuration dedicated data physical configured modified configured and security algorithm configuration secure algorithm configured. As an optional implementation manner, before sending the rrc configuration message, the base station selects an algorithm for performing security completion and encryption on the rrc configuration message, then performs security completion on the message using the selected security completion algorithm, then encrypts the message using the selected encryption algorithm, and preferentially uses the security completion and encryption algorithm carried in the rrc configuration request message in step 1100. After the terminal receives the rrc configuration, the terminal decrypts the message and performs security check to determine that the received message is valid rrc configuration, and after the UE determines that the valid rrc configuration is received, the UE establishes a connection for carrying control plane signaling data SRB and a connection DRB for carrying user plane data according to the information provided by the rrc configuration, and activates an access stratum security authentication AS security.
Step 1300, sending radio resource control configuration completion information to a network side, so that the network side sends a context setting response to a core network, and establishes a connection between an air interface and the core network.
In some embodiments, the terminal sends Rrc Configuration Complete information Rrc Configuration Complete to the network, where the Rrc Configuration Complete information Rrc Configuration Complete may perform security completion and/or encryption using a security completion encryption algorithm carried by the Rrc Configuration Request. After receiving the radio resource control configuration completion information Rrc configuration Complete, the network side sends a Context Setup Response to the core network, thereby completing establishment of connection between the air interface and the core network, and then performing data transmission by using the establishment service.
In the technical solution provided in this embodiment, both the radio resource control and the connection management of the terminal are in an idle state, and when data transmission is required, the establishment of an air interface data path and data transmission may be completed only through 3 air interface messages, namely, the radio resource control configuration request, the radio resource control configuration information, and the radio resource control configuration completion information. Meanwhile, the technical scheme provided by the embodiment does not change the original message interaction flow between the network side and the core network, and the initialization setting of the context information is realized through the interaction between the network side and the core network, so that the context information of the terminal does not need to be stored. Therefore, the technical scheme in the embodiment not only reduces the energy consumption of the terminal, but also does not bring extra memory requirements to the network side and the core network.
As an alternative implementation, as shown in fig. 2, in step 1200, the decrypting and integrity check of the rrc configuration information includes:
step 1210, acquiring a complete security and encryption algorithm set supported by the terminal;
in some embodiments, the set of integrity protection and encryption algorithms refers to the set of all integrity protection and encryption algorithms that the terminal is capable of supporting.
Step 1220, sequentially adopting the algorithms in the algorithm set to decrypt the radio resource control configuration information;
in some embodiments, the terminal performs decryption and re-security check on the received rrc configuration message in sequence by using each security completion and encryption algorithm in the algorithm set, and when the security completion check is successful, it may be determined that the decryption and security completion algorithm currently used by the terminal is an algorithm for performing security completion and encryption on the rrc configuration message at the network side. And the terminal obtains the contents of the rrc configuration message through the decryption operation. In order to improve efficiency, the terminal preferentially uses the security completion and encryption algorithm expected by the terminal carried by the Rrc Configuration Request in step 1100.
Step 1230, when the algorithm in the algorithm set fails to decrypt the rrc configuration information, the validity of the rrc configuration information is checked.
In some embodiments, after all the security and encryption algorithms in the algorithm set are tried, a security and encryption algorithm with successful security check is not found yet, and one possibility is that the network side does not encrypt and complete security for Rrc Configuration, at this time, the content of the Rrc Configuration message is directly checked, and if the content is legal, the Rrc Configuration message is a legal message, and the terminal may continue to process the message; another possibility is that the network side encrypts and finishes the radio resource control Configuration information Rrc Configuration using an encryption or a finishing algorithm that is not supported by the terminal, and at this time, the terminal can only discard the received radio resource control Configuration information Rrc Configuration.
As an alternative implementation manner, as shown in fig. 3, in step 1200, after receiving the radio resource control configuration information sent by the network side, the method includes:
step 1240, when the radio resource control configuration information has an error;
in some embodiments, when some parameters indicated by the Rrc Configuration information are not compatible or have errors (for example, there is an error in the physical layer parameter Configuration check), the UE may be unable to process the parameters.
In order to process the error, the processing is required to be carried out according to the current cell updating state, so the current cell state is acquired firstly;
step 1251, when the cell is not updated, initiate a radio resource control setup request procedure;
in some embodiments, when the cell is not updated, that is, the access is still initiated in the original cell, since the Rrc Configuration has already occurred, it is indicated to some extent that the success rate of continuing to use the Rrc Configuration on the current cell may be relatively low, and in order to increase the success rate, the new access procedure uses an Rrc setup request rrcstupreq/RrcSetup procedure. In other embodiments, since the reason for the failure may not be caused by the Rrc Configuration procedure, the reason for the failure may have been eliminated when the connection is performed next time, in which case, the use of the Rrc Configuration procedure can save air interface signaling. Therefore, it is possible to attempt to establish a connection using the rcconfiguration flow a plurality of times, and when failing a plurality of times, it is possible to initiate a request for establishing a connection using the Rrc Configuration/rcsetup flow.
Step 1252, when the cell is updated, initiate a radio resource control setup request procedure or reinitiate a radio resource control configuration request.
In some embodiments, when the new cell supports Rrc Configuration information Rrc Configuration, an Rrc Configuration request RrcConfiguration req/RrcConfiguration procedure may be selected, and an Rrc setup request rrcstupreq/RrcSetup procedure may be selected. In some embodiments, the terminal may acquire whether the new cell supports radio resource control Configuration information Rrc Configuration through broadcast information on the network side.
An embodiment of the present invention provides a service establishment method, which is applied to a network side device, and as shown in fig. 4 and fig. 6, the method includes:
step 2100, receiving a radio resource control configuration request sent by a terminal, and sending a message for initializing the terminal to a core network according to the radio resource control configuration request; wherein radio resource control and connection management of the terminal are in an idle state;
in some embodiments, the terminal is a terminal already registered to the network, and the radio resource control and connection management of the terminal are both in an IDLE state in order to save resources when there is no data transmission, for example, the terminal enters a state of RRC _ IDLE, CM _ IDLE. At this time, the terminal and the network side do not need to store the terminal context data related to the service. The network side can carry some encryption or security completion algorithms used by the recommended terminal in the radio resource control release message for the terminal to subsequently access the network side for use. When the terminal has uplink data to be transmitted or sends a paging message to the terminal because the network side has downlink data to be transmitted, a non-access stratum of the terminal triggers a service request, and radio resource control of the terminal sends a radio resource control configuration request RrcConfigurationRequest on an air interface. After receiving the radio resource control configuration Request RrcConfigurationRequest, the network side sends a Message Initial UE Message of an initialization terminal to the core network, and after receiving the Message Initial UE Message of the initialization terminal, the core network sends an initialization Context Setup Request Initial Context Setup Request to the network side.
As an optional implementation manner, the sending the radio resource control configuration request to the network side includes: and carrying more than one complete security and encryption algorithm, the content of the service request, the terminal identity information and the selected network identity information in the radio resource control configuration request so that the network side stores the complete security and encryption algorithm and the terminal identity information and sends the service request content and the selected network identity information to a core network. In some embodiments, the rrc configuration request carries one or more of the security and encryption algorithms desired by the terminal, the service request content, the terminal Identity information ue-Identity, and the selected network Identity information selected plmn-Identity. After receiving the Message, the network side stores the information such as the complete security and encryption algorithm expected by the terminal, the terminal Identity information UE-Identity and the like, and simultaneously sends the service request content service request, the selected network Identity information UE-Identity and the like to the core network through initializing the Message Initial UE Message of the terminal. In other embodiments, the message content carried by the rrc configuration request may not include the security completion and encryption algorithm.
Step 2200, receiving an initialization context setting request sent by a core network according to the message of the initialization terminal; sending wireless resource control configuration information to the terminal according to the initialization context setting request;
in some embodiments, after receiving the initial Context Setup Request, the network side allocates air interface resources and issues radio resource control configuration information RrcConfiguration to the terminal, where the radio resource control configuration information RrcConfiguration includes configuration information such as control plane signaling data SRB, user plane data DRB, medium access control layer MAC, physical configuration dedicated data physical configured modified configured and security algorithm configuration secure algorithm configured. As an optional implementation manner, before sending the rrc configuration message, the base station selects an algorithm for performing security completion and encryption on the rrc configuration message, then performs security completion on the message using the selected security completion algorithm, then encrypts the message using the selected encryption algorithm, and preferentially uses the security completion and encryption algorithm carried in the rrc configuration request message in step 2100. After the terminal receives the rrc configuration, the terminal decrypts the message and performs security check to determine that the received message is valid rrc configuration, and after the UE determines that the valid rrc configuration is received, the UE establishes a connection for carrying control plane signaling data SRB and a connection DRB for carrying user plane data according to the information provided by the rrc configuration, and activates an access stratum security authentication AS security.
Step 2300, receiving the radio resource control configuration completion information sent by the terminal, and sending an initialization context setup response to the core network according to the radio resource control configuration completion information, so as to complete the previous connection between the air interface and the core network.
In some embodiments, the terminal sends Rrc Configuration Complete information Rrc Configuration Complete to the network, where the Rrc Configuration Complete information Rrc Configuration Complete may perform security completion and/or encryption using a security completion encryption algorithm carried by the Rrc Configuration Request. After receiving the radio resource control configuration completion information Rrc configuration Complete, the network side sends a Context Setup Response to the core network, thereby completing establishment of connection between the air interface and the core network, and then performing data transmission by using the establishment service.
In the technical solution provided in this embodiment, both the radio resource control and the connection management of the terminal are in an idle state, and when data transmission is required, the establishment of an air interface data path and data transmission may be completed only through 3 air interface messages, namely, the radio resource control configuration request, the radio resource control configuration information, and the radio resource control configuration completion information. Meanwhile, the technical scheme provided by the embodiment does not change the original message interaction flow between the network side and the core network, and the initialization setting of the context information is realized through the interaction between the network side and the core network, so that the context information of the terminal does not need to be stored. Therefore, the technical scheme in the embodiment not only reduces the energy consumption of the terminal, but also does not bring extra memory requirements to the network side and the core network.

the request module is used for responding to the data transmission requirement and sending a wireless resource control configuration request to the network side; so that the network side acquires the context setting request from the core network and allocates air interface resources for the terminal;
in some embodiments, the terminal is a terminal already registered to the network, and the radio resource control and connection management of the terminal are both in an IDLE state in order to save resources when there is no data transmission, for example, the terminal enters a state of RRC _ IDLE, CM _ IDLE.

The network side can carry some encryption or security completion algorithms used by the recommended terminal in the radio resource control release message for the terminal to subsequently access the network side for use. When the terminal has uplink data to be transmitted or sends a paging message to the terminal because the network side has downlink data to be transmitted, a non-access stratum of the terminal triggers a service request, and radio resource control of the terminal sends a radio resource control configuration request RrcConfigurationRequest on an air interface. After receiving the radio resource control configuration Request RrcConfigurationRequest, the network side sends a Message Initial UE Message of an initialization terminal to the core network, and after receiving the Message Initial UE Message of the initialization terminal, the core network sends an initialization Context Setup Request Initial Context Setup Request to the network side.

In some embodiments, the rrc configuration request carries one or more of the security and encryption algorithms desired by the terminal, the service request content, the terminal Identity information ue-Identity, and the selected network Identity information selected plmn-Identity.

In other embodiments, the message content carried by the rrc configuration request may not include the security completion and encryption algorithm.

As an optional implementation manner, before sending the rrc configuration message, the base station selects an algorithm for performing security completion and encryption on the rrc configuration message, then performs security completion on the message using the selected security completion algorithm, then encrypts the message using the selected encryption algorithm, and preferentially uses the security completion and encryption algorithm carried in the rrc configuration request message in step 1100.
As an optional implementation manner, the receiving module includes a checking sub-module, configured to perform decryption and integrity check on the rrc configuration information. In some embodiments, after the terminal receives the rrc configuration information, the terminal decrypts the message and performs security check on the message to determine that the received message is valid rrc configuration information, and after the UE determines that the valid rrc configuration information is received, the UE establishes a connection for carrying control plane signaling data SRB and a connection DRB for carrying user plane data according to information provided by the rrc configuration information, and activates an access stratum security AS security.

After receiving the radio resource control configuration completion information Rrc configuration Complete, the network side sends a Context Setup Response to the core network, thereby completing establishment of connection between the air interface and the core network, and then performing data transmission by using the establishment service.
In the technical solution provided in this embodiment, both the radio resource control and the connection management of the terminal are in an idle state, and when data transmission is required, the establishment of an air interface data path and data transmission may be completed only through 3 air interface messages, namely, the radio resource control configuration request, the radio resource control configuration information, and the radio resource control configuration completion information. Meanwhile, the technical scheme provided by the embodiment does not change the original message interaction flow between the network side and the core network, and the initialization setting of the context information is realized through the interaction between the network side and the core network, so that the context information of the terminal does not need to be stored. Therefore, the technical scheme in the embodiment not only reduces the energy consumption of the terminal, but also does not bring extra memory requirements to the network side and the core network.

And the terminal obtains the contents of the rrc configuration message through the decryption operation.

And the checking unit is used for checking the validity of the radio resource control configuration information when the algorithms in the algorithm set fail to decrypt and completely protect the radio resource control configuration information.
In some embodiments, after all the security and encryption algorithms in the algorithm set are tried, a security and encryption algorithm with successful security check is not found yet, and one possibility is that the network side does not encrypt and complete security for Rrc Configuration, at this time, the content of the Rrc Configuration message is directly checked, and if the content is legal, the Rrc Configuration message is a legal message, and the terminal may continue to process the message; another possibility is that the network side encrypts and finishes the radio resource control Configuration information Rrc Configuration using an encryption or a finishing algorithm that is not supported by the terminal, and at this time, the terminal can only discard the received radio resource control Configuration information Rrc Configuration.

in some embodiments, when some parameters indicated by the Rrc Configuration information are not compatible or have errors (for example, there is an error in the physical layer parameter Configuration check), the UE may be unable to process the parameters.
The state judgment submodule is used for acquiring the current cell state;
in some embodiments, in order to process the error, the processing needs to be performed according to the current cell update state, so the current cell state is obtained first;
the first request submodule is used for initiating a radio resource control setting request process when the cell is not updated;
in some embodiments, when the cell is not updated, that is, the access is still initiated in the original cell, since the Rrc Configuration has already occurred, it is indicated to some extent that the success rate of continuing to use the Rrc Configuration on the current cell may be relatively low, and in order to increase the success rate, the new access procedure uses an Rrc setup request rrcstupreq/RrcSetup procedure. In other embodiments, since the reason for the failure may not be caused by the Rrc Configuration procedure, the reason for the failure may have been eliminated when the connection is performed next time, in which case, the use of the Rrc Configuration procedure can save air interface signaling. Therefore, it is possible to attempt to establish a connection using the rcconfiguration flow a plurality of times, and when failing a plurality of times, it is possible to initiate a request for establishing a connection using the Rrc Configuration/rcsetup flow.
And the second request submodule is used for initiating a radio resource control setting request process or re-initiating a radio resource control configuration request when the cell is updated.
In some embodiments, when the new cell supports Rrc Configuration information Rrc Configuration, an Rrc Configuration request RrcConfiguration req/RrcConfiguration procedure may be selected, and an Rrc setup request rrcstupreq/RrcSetup procedure may be selected. In some embodiments, the terminal may acquire whether the new cell supports radio resource control Configuration information Rrc Configuration through broadcast information on the network side.
