Detailed Description
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.
The embodiment of the invention discloses a radio resource control protocol stack system, which is shown in figure 1 and comprises the following components:
a first functional unit 101, a second functional unit 102, and a control unit 103;
specifically, the inventive idea of the Radio Resource Control protocol stack system provided in the embodiment of the present invention is to perform function division on a Radio Resource Control (RRC) protocol stack function originally integrated or coupled in a set of complete processing procedures and code logic for implementing the RRC protocol stack function, and divide the originally complex processing function and code logic into small functional units, so as to make the function division of the entire RRC protocol stack clearer.
Based on the above inventive concept, the RRC protocol stack system provided in the embodiment of the present invention is divided into a first functional unit 101, a second functional unit 102, and a control unit. The first functional unit 101 is configured to implement a relatively complete upper RRC protocol stack function, the second functional unit 102 is configured to implement a relatively detailed function process in a lower layer, and the first functional unit 101 and the second functional unit 102 jointly implement the RRC protocol stack function under the control of the control unit 103.
It should be noted that, in the embodiment of the present invention, only the first functional unit 101 and the second functional unit 102 are used to describe the inventive idea of dividing the RRC protocol stack function. However, the technical solution of the embodiment of the present invention does not limit that the function of the RRC protocol stack system must be divided into two functional units, and when the technical solution of the embodiment of the present invention is actually implemented, complicated or large-scale system functions may be divided according to requirements or system performance.
The first functional unit 101 includes a plurality of rrc function modules, each rrc function module is configured to implement an rrc protocol processing function by calling a function processing module in the second functional unit 102; wherein, the implementing a radio resource control protocol processing function includes completing the transition of a radio resource control state in the process of implementing the processing function;
specifically, in the embodiment of the present invention, complex and large-scale RRC protocol stack functions are modularized, and in the first functional unit 101, each radio resource control functional module is used to implement an RRC protocol stack processing function, for example, to implement functions such as radio connection control, cell search and cell selection, and mobility management. Each function module is relatively independent, information interaction is realized through a communication interface, and all the function modules cooperate with each other to realize all RRC protocol stack functions.
Further, in the process of implementing the RRC protocol stack function, the transition change of the RRC state is accompanied. Since the RRC protocol stack is complex in function, the change of RRC state is also various. In the embodiment of the present invention, the complex RRC state change is divided according to the RRC protocol stack function, specifically, the RRC state change when the same RRC protocol stack function is implemented is divided into the radio resource control function module for implementing the RRC protocol stack function. That is, in one RRC function module, while implementing a certain RRC protocol stack function, RRC state transition in the process of implementing the function is completed.
And, the change of the RRC state is realized in a state machine mode. It can be understood that, in a specific implementation, each radio resource control function module is implemented in a state machine, and each state machine implements an RRC protocol stack function while implementing RRC state transition. The implementation of each state machine includes definitions of states, events, and event handlers.
Furthermore, in the embodiment of the present invention, the object-oriented encapsulation characteristic is adopted for encapsulating each state machine, and the realization of the state machine is encapsulated through macro definition, so that when the state machine is added and modified, the internal operation principle is hidden for developers, and only the encapsulated interface is needed.
The second functional unit 102 includes a plurality of function processing modules, each of which stores a processing function, and when the radio resource control functional module in the first functional unit 101 calls the function processing module, the function processing module runs the processing function stored therein;
a control unit 103, configured to control the first functional unit 101 and the second functional unit 102 to implement a radio resource control protocol processing function.
Specifically, the second functional unit 102 includes a plurality of function processing modules, each function processing module stores a processing function for implementing a processing procedure, and runs the function, that is, a certain processing procedure implementing the RRC protocol stack function. For example, the connection establishment process may be implemented by running a connection establishment processing function in the connection establishment module.
It can be understood that, in the RRC protocol stack system provided in the embodiment of the present invention, the processing function at the lower layer for implementing the RRC protocol stack function is made into an independent function processing module for being called by the module at the upper layer for implementing the RRC protocol stack function, so as to further simplify the function module in the first functional unit 101. In addition, the processing function in the function processing module is a common processing function, and any function module in the first functional unit 101 can call the function processing module in the second functional unit 102 as needed.
Further, the function processing module in the second functional unit 102 is also implemented in a state machine, and is encapsulated by using an object-oriented encapsulation property.
The control unit 103 mainly implements control over the state machines in the first functional unit 101 and the second functional unit 102, and specifically controls interaction between the state machines and start and stop of operation, so that the state machines operate in cooperation, and an RRC protocol stack function is implemented.
It can be understood that, in the embodiment of the present invention, since the relevance or coupling between the functional modules of the RRC protocol stack system is low, the functional modules in the RRC protocol stack system can be added or deleted conveniently. This is also one of the advantages of the RRC protocol stack system proposed by the embodiment of the present invention.
The radio resource control protocol stack system provided by the invention comprises a first functional unit 101, a second functional unit 102 and a control unit 103. The first functional unit 101 includes a plurality of radio resource control functional modules, each of which is configured to implement a radio resource control protocol processing function by calling a function processing module in the second functional unit 102; the second functional unit 102 includes a plurality of function processing modules, each of which stores a processing function, and when the radio resource control functional module in the first functional unit 101 calls the function processing module, the function processing module runs the processing function stored therein; the control unit is configured to control the first functional unit 101 and the second functional unit 102 to implement a radio resource control protocol processing function. In the radio resource control protocol stack system, a plurality of radio resource control function modules and function processing modules are arranged and are respectively used for realizing the functions of the radio resource control protocol stack, so that the coupling of all the functions of the radio resource control protocol stack is avoided, the function differentiation and the code logic of the whole protocol stack system are clearer, and the management and the maintenance are more convenient.
Optionally, in another embodiment of the present invention, referring to fig. 2, the first functional unit 101 includes:
a connection control module 1011 for implementing a connection control function of the radio resource control protocol;
a cell selection and search module 1012, configured to implement a cell selection and search function of a radio resource control protocol;
a public land mobile network searching and selecting module 1013 for implementing a public land mobile network searching and selecting function of a radio resource control protocol;
a system information acquisition module 1014, configured to implement a system information acquisition function of a radio resource control protocol;
a measurement control module 1015, configured to implement a measurement control function of a radio resource control protocol;
a protocol coding module 1016, configured to implement a protocol coding function of a radio resource control protocol;
a protocol decoding function 1017 for implementing a protocol decoding function of the radio resource control protocol.
Specifically, the RRC protocol stack function mainly includes seven functions, namely, a connection control function, a cell selection and search function, a Public Land Mobile Network (PLMN) search and selection function, a system information acquisition function, a measurement control function, a protocol coding function, and a protocol decoding function. In the embodiment of the invention, each function is realized by one functional module. Each functional module may call a function processing module in the second functional unit 102 to complete a necessary function processing procedure when implementing the RRC protocol stack function. Taking the flow for implementing the connection establishment function shown in fig. 3 as an example, when the connection control module 1011 receives a connection establishment request sent by the non-access stratum in the idle campedoncoCell state, it will call the connection establishment function processing module in the second functional unit 102 to implement the connection establishment process; after the connection establishment process is completed, the connection establishment function processing module feeds back the result to the connection control module 1011, and the connection control module 1011 transitions from the idle campedoncell state to the Connected state.
Each functional module in the first functional unit 101 is implemented as a state machine. And in order to simplify the realization of the state machine, only state definition, event definition and event processing function definition are needed, and the internal operation process of the state machine is packaged into a common interface for calling when the state machine is defined and used.
Taking the RRC module as an example, the state machine implementation can be defined by the states:
HSM_STATE_LIST_BEGIN(RRC)
HSM_STATE_ADD(RRC,IldeNoCell)
HSM_STATE_ADD(RRC,Connected)
HSM_STATE_LIST_END(RRC)
state machine event definition
HSM_EVENT_LIST_BEGIN(RRC)
HSM_EVENT_ADD(DC_CONNECTION_ESTABLISH_REQ)
HSM_EVENT_ADD(DC_CONNECTION_RELEASE_REQ)
HSM_EVENT_LIST_END(RRC)
Event handling function definition
HSM_STATE_DEF_BEGIN(RRC,Connected)
HSM_STATE_EVENT_HANDLE(RRC_Connected_Handle_NAS_ConnectionEstablishReq)
HSM_STATE_EVENT_HANDLE(RRC_Connected_Hanlde_NAS_ConnectionReleaseReq)
In addition to the above interfaces, the embodiments of the present invention further define interfaces such as SM _ HSM _ DEF (defining STATE machine), HSM _ SET _ NEXT _ STATE (STATE transition), and HSM _ TERMINATE _ FSM (terminating STATE machine). The packaging design of the state machine based on the object-oriented idea ensures that the event processing program does not need to know the details of the current state, thereby ensuring the stability of the system and simplifying the development process.
Optionally, in another embodiment of the present invention, referring to fig. 4, the second functional unit 102 includes:
a connection establishing module 1021 for storing a connection establishing processing function, and for operating the connection establishing processing function to realize a connection establishing function;
a cell search module 1022, storing a cell search processing function, configured to run the cell search processing function to implement a cell search function;
the resource configuration module 1023 is used for storing a resource configuration processing function and running the resource configuration processing function to realize a resource configuration function;
the resource release module 1024 is used for storing a resource release processing function and running the resource release processing function to realize a resource release function;
an L1A configuration module 1025 that stores an L1A configuration processing function, and is configured to run the L1A configuration processing function to implement an L1A configuration function;
an L1A reset module 1026, which stores an L1A reset processing function, and is configured to run the L1A reset processing function to implement an L1A reset function;
a security configuration module 1027, storing a security configuration processing function, configured to run the security configuration processing function to implement a security configuration function;
an SIA configuration module 1028 that stores an SIA configuration processing function, and is configured to run the SIA configuration processing function to implement an SIA configuration function;
Specifically, each function processing module in the second functional unit 102 stores a processing function, and the processing function is used for implementing a processing procedure of an RRC protocol stack function. Each function processing module in the second functional unit 102 is implemented as a state machine. And in order to simplify the realization of the state machine, only state definition, event definition and event processing function definition are needed, and the internal operation process of the state machine is packaged into a common interface for calling when the state machine is defined and used.
Based on the design, when the RRC protocol is modified according to special requirements, corresponding modules or processes can be added and deleted. If functions need to be added, only a new state machine needs to be defined, and the original software structure does not need to be changed. For example, adding a Handover function, a new process Handover may be defined, defining the corresponding state machine state, events and event handling functions.
Specifically, first, a process definition is added to the original architecture:
defining states WaitingfReconfigCnf and WaitingfForHandoverAccess Cnf corresponding to the Handover process;
timing state machine events HANDOVER _ TIMER _ EXPIRY _ IND, HANDOVER _ CONFIG _ CNF and HANDOVER _ ACCESS _ CNF;
processing HANDOVER _ TIMER _ EXPIRY _ IND and HANDOVER _ CONFIG _ CNF events in the Waitingforconfigucnf state, and processing HANDOVER _ TIMER _ EXPIRY _ IND and HANDOVER _ ACCESS _ CNF events in the WaitingforcandcoveraccessCf state, and defining corresponding processing functions.
After the Handover state machine is added, when the RRC module receives the reconfiguration information of the E-UTRAN, the Handover process is called, the lower layer state machine is triggered, and the switching process is completed.
The embodiment of the present invention discloses a method for implementing radio resource control, which is applied to the control unit 103 of the radio resource control protocol stack system, and as shown in fig. 5, the method includes:
s501, receiving wireless resource control processing request information;
specifically, the radio resource control processing request information may be radio resource control request information sent by a non-access stratum, and is used for requesting to implement RRC layer control protocol processing.
S502, according to the radio resource control processing request message, controlling the first functional unit 101 to call a function processing module in the second functional unit 102, thereby completing the radio resource control processing.
Specifically, in the embodiment corresponding to the radio resource control protocol stack system, various RRC protocol stack functions of the radio resource control protocol stack system are all implemented by the first functional unit 101 of the system. When the control unit 103 receives the RRC processing request, it first analyzes which RRC control processes need to be implemented; then, the first functional unit 101 is controlled to start operating, and the RRC control processing function to be implemented is implemented. When receiving the control instruction from the control unit 103, the first functional unit 101 calls a processing function in the function processing module in the second functional unit 102 to implement an RRC control processing function.
By adopting the method for realizing the radio resource control, the complex RRC protocol stack function is divided into different functional units for completion, the coupling degree of various RRC protocol stack functions and code logic is reduced, the realization process of each RRC protocol stack function is more convenient to know, and the management operations such as addition and deletion of the RRC protocol stack function are convenient to carry out.
Optionally, in another embodiment of the present invention, controlling the first functional unit 101 to call a function processing module in the second functional unit 102 to complete the radio resource control process includes:
the radio resource control function module in the first function unit 101, which is used for implementing the radio resource control processing function, is controlled to start to operate, so that the radio resource control function module completes the radio resource control processing by calling the function processing module in the second function unit 102.
Specifically, the first functional unit 101 includes a plurality of functional modules, and each functional module is configured to implement an RRC protocol stack function. When the control unit 103 controls the first functional unit 101 to implement the RRC protocol stack function, it actually controls the corresponding functional module in the first functional unit 101 to implement the RRC protocol stack function.
Based on the above principle, after receiving the radio resource control processing request message, the control unit 103 controls the function module in the first function unit 101 for implementing the radio resource control processing to start operating according to the request message, so that the function module completes the radio resource control processing by calling the function processing module in the second function unit 102.
The embodiment of the present invention discloses another method for implementing radio resource control, which is applied to the second functional unit of the radio resource control protocol stack system, and is shown in fig. 6, where the method includes:
s601, receiving calling request information sent by a first functional unit; the calling request information is sent by the first functional unit according to a radio resource control processing requirement and comprises calling request information of called function processing module information;
and S602, controlling the function processing module called by the first functional unit to start working according to the calling request information.
Specifically, when the first functional unit 101 calls a function processing module in the second functional unit 102 to implement the RRC protocol stack function, call request information is sent to the second functional unit 102, where the call request information includes information of the called function processing module.
After receiving the call request information, the second functional unit 102 controls the function processing module called by the first functional unit 101 to start working according to the call request information, runs the processing function stored in the function processing module, and assists the first functional unit 101 to implement the RRC protocol stack function.
When the method for realizing the radio resource control provided by the embodiment of the invention is adopted to realize the RRC protocol stack function, the function processing module in the functional unit at the lower level is called by the functional unit at the upper level to realize the RRC protocol stack function. The implementation process is layered, the code logic is clearer, and the implementation process of the RRC protocol stack function is convenient to manage and control.
Optionally, in another embodiment of the present invention, the starting of the function processing module called by the first functional unit 101 includes:
the function processing module that controls the first functional unit 101 to call starts to run the processing function stored in itself, and sends the running result to the first functional unit 101.
Specifically, the processing function in each function processing module of the second functional unit 102 is generally a function with a return value, so that the first functional unit can obtain the necessary parameters for implementing the RRC protocol stack function. Therefore, in the embodiment of the present invention, after the function processing module called by the first functional unit 101 starts to run the processing function stored in the function processing module, the function processing module is further controlled to return the function running result to the first functional unit 101, so that the first functional unit 101 acquires the data information necessary for implementing the RRC protocol stack function.
The embodiment of the present invention further discloses a device for implementing radio resource control, which is applied to the control unit of the radio resource control protocol stack system, and as shown in fig. 7, the device includes:
an information receiving module 701, configured to receive radio resource control processing request information;
