Description
Technical Field
The embodiment of the invention relates to the technical field of communication, in particular to a terminal access method, equipment and a system.
Background
With the popularization and rapid development of networks, the number of terminals deployed in the networks is increasing, and especially in a Machine to Machine (M2M) network technology, the number of terminals deployed can be measured by a large amount. In practical application, when a terminal needs to access to a network through a base station, different terminals have different service data types and different delay sensitivity characteristics, and meanwhile, in different application scenarios, uploaded data of the terminal have different priority levels, so that corresponding access strategies need to be selected for the terminal under various different state combinations, and various defects caused by unreasonable access strategies in the access process are avoided.
In the prior art, an access policy of a terminal can be generally selected through two schemes: the first scheme is that when a terminal is accessed to a network, the terminal selects a corresponding access strategy according to state conditions such as user grade information and service grade information of the terminal, and the terminal can select different access strategies to access the network corresponding to different user grades and service grades; the second scheme is that after selecting a corresponding access strategy, the terminal sends a corresponding access random code to a base station at the network side, and the base station judges whether the access random code needs to be allocated to the terminal again according to the received access random code, various grades of state information of the terminal and the load state of the network side, so that the terminal is accessed to the network according to different access strategies.
However, the inventor finds that the two schemes have certain defects in the process of implementing the invention: for the first scheme, in practical application, a network access flow of a terminal is not only related to the self-capability state of the terminal, but also related to the current real-time load state of a network, and in the first scheme, the terminal selects an access strategy according to the self-state, and the current load state of the network side is not considered, so that the resources of the network side cannot be fully utilized in time; as for the second scheme, the selection and control of the terminal access policy are mainly performed on the network side, so when there are a large number of terminals to be simultaneously accessed to the network, the base station needs to be responsible for controlling the access of the terminals in addition to processing the centralized transmission of a large amount of data, which not only causes a large number of conflicts on the access channel, but also causes a large processing burden to the base station itself.

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 some, but not all, embodiments of the present invention. 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.
Fig. 1 is a flowchart of a first embodiment of a terminal access method of the present invention, and as shown in fig. 1, the method of the present embodiment includes the following steps:
step 100, when determining that a network access requirement exists, determining a corresponding access strategy according to a service grade corresponding to a service to be accessed and a current load high-low state of a network;
in a data communication network, when a terminal determines that it needs to access to the network to implement sending or receiving of data according to a message issued by a network side, for example, a paging message of the network side for an offline terminal, or according to an upload requirement of data in a cache, that is, when it determines that there is a network access requirement for the terminal, it executes an operation of network access according to a certain access policy. In practical application, because the working mode and the service information of the terminal can be in various different states, and meanwhile, the terminal can be in various different application scenes corresponding to the accessed network side, how to select a reasonable access strategy for the terminal to be accessed into the network according to practical situations so as to avoid various defects possibly occurring when the terminal is accessed and solve the problem that the terminal needs to be considered before the access operation is executed.
Specifically, in this embodiment, when the terminal learns that there is a network access requirement, the terminal first detects a Service state of the terminal, specifically, the terminal determines a Service level of the terminal by detecting Service type information, such as delay sensitive information, quality of Service (QoS) and the like, of a Service to be accessed that has a data transmission requirement. Further, since in practical applications, the access of the terminal is also related to the current real-time load status of the network, for example, when the real-time load of the network is in a heavy situation, the terminal should first transmit data with higher service priority into the network, and may temporarily disregard the transmission of data with lower priority, and at the same time, may select an access policy with high priority for the terminal; when the real-time load of the network is in a light state, the terminal should allow users with low priority and low service type priority to access in time, and can select an access strategy with high priority for the terminal to access into the network quickly, so that the resources on the network side can be utilized sufficiently in time.
Therefore, in this embodiment, after the terminal detects itself to obtain the service class corresponding to the service to be accessed, in order to fully refer to the influence of the load state of the network side on the terminal access process, the terminal further obtains the current real-time load high-low state information of the network from the base station, so as to know and analyze the current load high-low state of the network side. After the terminal respectively acquires the service level of the terminal and the load state of the network side, a corresponding access strategy can be determined for the terminal according to the acquired two pieces of relevant information, wherein the access strategy is an access strategy which is respectively adaptive to the terminal state and the network state in the terminal access process.
And step 101, accessing to a corresponding network according to the determined access strategy.
And the terminal selects a corresponding access strategy according to the influence factors of the terminal and the network side on the current access process, and then accesses the terminal into the corresponding network through the corresponding base station according to the selected access strategy. The selected access strategy fully considers the influence of the access process of the service grade state of the terminal and the current real-time load state of the network side, so that the terminal is accessed into the network according to the access strategy, the current network resource can be fully utilized according to the current load state of the network, and the condition that the terminal which can be accessed into the network cannot be accessed into the network in time due to the fact that the resource of the network side is not effectively utilized can be avoided. Furthermore, because the selection and the control of the access strategy are carried out at the terminal side in the embodiment of the invention, even if a large number of terminals execute the network access process at the same time, the base station is not required to control the access process of the terminals, thereby greatly reducing the processing burden of the base station and accelerating the network access process of the terminals.
In the terminal access method of the embodiment, the terminal selects the corresponding access strategy according to the service grade of the service to be accessed and the real-time load condition of the network side in the process of accessing the terminal into the network, so that the selected access strategy can fully consider the influence of the network side on the access process, and the terminal can fully utilize the network side resource in time when executing the network access operation according to the selected access strategy.
Fig. 2 is a flowchart of a second embodiment of a terminal access method of the present invention, and as shown in fig. 2, the method of the present embodiment includes the following steps:
step 200, the terminal inquires the service grade information corresponding to the service to be accessed according to the time delay sensitivity degree of the service to be accessed;
in this embodiment, in order to clarify the service state of the terminal, the service is divided into a plurality of corresponding service levels on the terminal side in advance according to different service delay sensitivity degrees, each service level corresponds to a certain delay sensitivity degree of the service, and when the terminal determines that the terminal needs to access the network after judgment, the terminal can obtain the service level information corresponding to the service to be accessed according to the delay sensitivity degree of the service to be accessed in the access requirement. Specifically, in this step, the query of the terminal for its own service class may be implemented by establishing a mapping relationship list corresponding to the service delay sensitivity level and the service class in the terminal in advance, and when the terminal has a network access requirement, querying the service class of the service to be accessed in the pre-established mapping relationship list according to the delay sensitivity level corresponding to the service to be accessed.
It should be noted that, if there is a data transmission requirement corresponding to multiple services to be accessed in a certain network access requirement of the terminal, since a service class corresponding to the service can be queried in the mapping relationship list for each service to be accessed, in order to ensure that a high-level service of the terminal can be quickly connected to the network in the network access process, the terminal selects service class information corresponding to a service with the highest service class as service class information corresponding to the terminal in the network access process, and performs selection control of an access policy.
Step 201, a terminal receives load grade information sent by a base station, wherein the load grade information indicates the current real-time load high-low state of the base station;
in addition to querying the service class information of the service to be accessed by the terminal, in this embodiment, in order to obtain the influence of the network side on the access process, the terminal further obtains the current real-time load state of the network from the base station on the network side. Specifically, the load level state is known by the terminal receiving the load level information fed back by the base station. In this embodiment, the load status of the network side may be divided into a plurality of levels corresponding to various load statuses of the network, and accordingly, a mapping relationship list between the network load statuses and the load levels may be pre-established on the network side according to the level division. The network side can determine the current corresponding network load level by detecting the load state of the network side in real time and inquiring a preset mapping relation list, and then the network side sends the corresponding load level to the terminal in the form of load level information through the base station so that the terminal can know the current load state of the network.
In practical application, the base station may periodically issue the current latest load level information of the network to the terminal in a broadcast manner, and further, in the embodiment of the present invention, the network side may also issue the load level information to the terminal in a multicast or unicast manner.
Step 202, selecting an access strategy corresponding to the service grade information and the load grade information from a preset access strategy set;
after the terminal acquires the service level information of the terminal and the load high-low state of the network side, the access strategy corresponding to the access process can be selected according to the two state information. Specifically, in this embodiment, a plurality of different access policies may be set in advance on the terminal side according to a certain access parameter and access algorithm and according to different state combinations of various terminals and networks, where the access policies include different initial access window sizes, access backoff window algorithms, access time delays, and other information formed according to a certain access algorithm. After setting multiple Access strategies, the multiple Access strategies are combined into an Access Strategy Set (Access Strategy Set) at the terminal side, and each Access Strategy in the Access Strategy Set corresponds to a certain terminal service class and network load state and is equivalent to a two-input one-output mapping relation list. After the terminal knows the service level information of the terminal and the load high-low state of the access network, the terminal can inquire and select a corresponding access strategy from a preset access strategy set, and the selected access strategy is a reasonable access strategy according with the current terminal and network conditions.
Meanwhile, the determination of the access strategy by the terminal can be calculated by the terminal according to a preset access algorithm. Specifically, in this embodiment, an access algorithm capable of obtaining a terminal access policy through calculation may be further preset at the terminal side, where the access algorithm is equivalent to a calculation function with two inputs and one output, and after the terminal determines its own service level information and determines the load state of the network side, the service level information and the network load level information are used as input conditions of the preset access algorithm, so as to obtain an access policy in the current access process through calculation.
Optimally, in the network access process of the terminal, for the terminal, influence factors of the terminal on the whole network access process include the service grade corresponding to the service to be accessed and the user grade corresponding to the user of the terminal, that is, when the terminal selects or calculates the access strategy, if the terminal corresponds to different user priority levels, the specific strategy of the terminal for accessing the network can be correspondingly different, so as to ensure that the user with high priority level can be accessed into the network in advance.
Therefore, in this embodiment, the selection of the access policy in this step may also be obtained by the terminal through corresponding selection from the preset access policies and the current load high-low states of the network side according to the queried service class of the service to be accessed, and the user classes corresponding to the terminal, or through calculation according to a preset access algorithm. Correspondingly, a plurality of different access policies respectively corresponding to different combinations of service levels, user levels and network load high and low states are set in the preset access policy set, which is equivalent to a mapping relation list of three inputs and one output, or the preset access algorithm also forms a calculation function equivalent to three inputs and one output for considering the influence of the user level of the terminal on the access policy, and the terminal can inquire and select the corresponding access policy from the preset access policy set according to the obtained three information, or calculate the corresponding access policy by taking the determined three information as the input conditions of the access algorithm according to the preset access algorithm. The selected access strategy is a reasonable access strategy according with the service level of the terminal, the user level and the load level condition of the network.
Step 203, accessing to the corresponding network according to the selected access strategy.
And after selecting the corresponding access strategy according to the steps, the terminal can access to the corresponding network through the corresponding base station according to the selected access strategy. In this embodiment, the selected access policy fully considers the characteristic state of the terminal itself and the current real-time load state of the network side, so that the terminal accesses the network according to the access policy, and can fully utilize the current network resources according to the current load state of the network, thereby avoiding a situation that the network side should allow the terminal accessed into the network to fail to access the network in time due to the fact that the resources of the network side are not effectively utilized. Further, in this embodiment, since the selection and control of the access policy are performed on the terminal side, even when a large number of terminals execute the network access process at the same time, the base station does not need to control the access of the terminals, thereby greatly reducing the processing burden of the base station and accelerating the network access process of the terminals.
In the terminal access method of the embodiment, the terminal selects the corresponding access strategy according to the service level of the service to be accessed, the user level of the corresponding user and the real-time load condition of the network side in the process of accessing the terminal into the network, so that the selected access strategy can fully consider the influence of the network side on the access process, and the terminal can fully utilize the resources of the network side in time when executing the network access operation according to the selected access strategy.
