technical field

Embodiments of the present invention relate to the field of communication technologies, and in particular, to a terminal access method, device, and system.

Background technique

With the popularization and rapid development of the network, the number of terminals deployed in the network is increasing day by day, especially in the machine-to-machine (M2M) network technology, the number of deployed terminals can be measured by mass. In practical applications, when a terminal needs to access the network through a base station, since different terminals have different service data types and different delay-sensitive characteristics, at the same time, in different application scenarios, the uploaded data of the terminal has different priority levels , so under various combinations of states, it is necessary to select a corresponding access strategy for the terminal, so as to avoid various disadvantages caused by unreasonable access strategies during the access process.

In the prior art, there are usually two schemes to select the access strategy of the terminal: the first scheme is that the terminal selects the corresponding access policy according to its own user level information, service level information and other state conditions when accessing the network. Strategy, corresponding to different user levels and business service levels, the terminal can choose different access strategies to access the network; the second solution is that after the terminal selects the corresponding access strategy, it sends the corresponding access random code to the The base station on the network side, the base station judges whether it is necessary to re-allocate the access random code for the terminal according to the received access random code, various levels of status information of the terminal and the load status of the network side itself, so that the terminal can be allocated according to different The access policy is connected to the network.

However, the inventor found in the process of implementing the present invention that both of the above two solutions have certain defects: for the first solution, since in practical applications, the network access process of the terminal is not only related to the capability status of the terminal itself, It is also related to the current real-time load status of the network. In solution 1, the terminal selects an access strategy according to its own status, without considering the current load status on the network side, which may cause the resources on the network side to be unable to be fully utilized in a timely manner; and for In the second solution, the selection and control of terminal access policies are mainly carried out on the network side. Therefore, when there are a large number of terminals that need to access the network at the same time, the base station not only needs to handle the centralized transmission of a large amount of data, but also needs to be responsible for Terminal access is controlled, which will not only cause a large number of conflicts on the access channel, but also cause a large processing burden on the base station itself.

In order to make the purpose, 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 in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

FIG. 1 is a flow chart of Embodiment 1 of the terminal access method of the present invention. As shown in FIG. 1, the method of this embodiment includes the following steps:

Step 100, when it is determined that there is a need for network access, determine a corresponding access strategy according to the service level corresponding to the service to be accessed and the current load status of the network;

In a data communication network, when a terminal judges that it needs to access the network according to the message sent by the network side, such as the paging message for the offline terminal on the network side, or according to the upload requirement of the data in the cache, it needs to access the network to realize the data access Sending or receiving, that is, when it is judged that the terminal has a network access requirement, it will perform a network access operation according to a certain access strategy. In practical applications, since the working mode and service information of the terminal can be in many different states, and corresponding to the connected network side, it can be in many different application scenarios. Therefore, how to select the terminal according to the actual situation A reasonable access strategy is used to access the network to avoid various disadvantages that may occur when the terminal accesses, and it is a problem that must be considered before the terminal performs an access operation.

Specifically, in this embodiment, when the terminal learns that it has a network access requirement, it will first detect its own business service status, specifically referring to the delay-sensitive information of the service to be accessed by the terminal that requires data transmission. , Quality of Service (Quantity of Service, referred to as QoS) and other business service type information detection, to determine its own business service level. Furthermore, since in practical applications, terminal access is also closely related to the current real-time load status of the network, for example, when the real-time load of the network is heavy, the terminal should first transmit data with higher service priority to the In the network, the transmission of data with lower priority can be temporarily ignored, and at the same time, a high-priority access strategy can be selected for the terminal; when the real-time load of the network is in a lighter state, the terminal should allow low-priority Users with high-level and low-priority service types can access in time, and can select a high-priority access strategy for the terminal to quickly access the network, so that the resources on the network side can be fully utilized in a timely manner.

Therefore, in this embodiment, after the terminal obtains the service level corresponding to the service to be accessed through its own detection, in order to fully refer to the impact of the load status on the network side on the terminal access process, it will further obtain from the base station The current real-time load status information of the network is used to understand and analyze the current load status of the network side. After the terminal knows its own business service level and the load status of the network side, it can determine the corresponding access strategy for itself according to the two related information. The access strategy is related to the terminal access process. Access policies adapted to the terminal state and network state respectively.

Step 101, access to a corresponding network according to a determined access policy.

After the terminal selects the corresponding access strategy according to the influence factors of itself and the network side on the current access process, it will access the corresponding network through the corresponding base station according to the selected access strategy. Since the selected access strategy fully considers the influence of the service level status of the terminal itself and the current real-time load status of the network side on the access process, the terminal accesses the network according to the access strategy, and can follow the current network load status. The load state makes full use of the current network resources, so as to avoid the situation that the terminals that could have been connected to the network cannot be connected to the network in time due to the resources on the network side not being effectively used. Furthermore, since the selection and control of the access strategy in the embodiment of the present invention are all performed on the terminal side, even if there are a large number of terminals performing the network access process at the same time, since the base station does not need to control the terminal access process, thus The processing burden of the base station is greatly reduced, and the network access process of the terminal is accelerated.

In the terminal access method of this embodiment, during the process of terminal access to the network, the terminal itself selects the corresponding access strategy according to the service level of the service to be accessed and the real-time load situation on the network side, so that the selected The selected access policy can fully consider the influence of the network side on the access process, so that when the terminal performs network access operations according to the selected access policy, it can make full use of network side resources in a timely manner. Further, due to In the embodiments of the present invention, the control of the access process is performed on the terminal side, thereby reducing the processing burden of the base station when a large number of terminals access, and accelerating the process of terminal access.

FIG. 2 is a flowchart of Embodiment 2 of the terminal access method of the present invention. As shown in FIG. 2, the method of this embodiment includes the following steps:

Step 200, the terminal queries service level information corresponding to the service to be accessed according to the delay sensitivity of the service to be accessed;

In this embodiment, in order to clarify the business service status of the terminal, the business is divided into corresponding multiple business service levels according to different business delay sensitivities in advance on the terminal side, and each business service level is related to a certain delay sensitivity of the business. Correspondingly, when the terminal judges that it needs to access the network, according to the delay sensitivity of the service to be accessed in this access demand, it can query and obtain the service level information corresponding to the service to be accessed. Specifically, in this step, the terminal queries its own business service level by establishing a mapping relationship list corresponding to business delay sensitivity and business service level in the terminal in advance, and when the terminal has a network access requirement, according to the pending The delay sensitivity corresponding to the incoming business is realized by querying the business service level of the incoming business in the pre-established mapping relationship list.

It should be noted that, if in a certain network access requirement of the terminal, there is a data transmission requirement corresponding to multiple services to be accessed at the same time, since each service to be accessed can be included in the above mapping relationship list Query the business service level corresponding to the business, and in order to ensure that the high-level business of the terminal can be quickly connected to the network during the network access process, the terminal will select the business service level information corresponding to the business with the highest business service level As the service level information corresponding to the terminal in this access process, the selection control of the access policy is performed.

Step 201, the terminal receives load level information sent by the base station, the load level information indicates the current real-time load level of the base station;

In addition to querying the service level information of the service to be accessed by the terminal, in this embodiment, in order to know the influence of the network side on the access process, the terminal will also obtain the network current status from the base station on the network side. real-time load status. Specifically, the high or low state of the load is learned by the terminal receiving the load level information fed back by the base station. In this embodiment, corresponding to various high and low load states of the network, the load state on the network side can be divided into multiple levels. A list of mapping relationships. The network side can determine the current corresponding network load level by detecting its own load level in real time and querying the preset mapping relationship list, and then the network side sends the corresponding load level in the form of load level information through the base station To the terminal, so that the terminal can know the current load level of the network.

In practical applications, the base station can periodically send the latest current load level information of the network to the terminal in the form of broadcasting. Furthermore, in the embodiment of the present invention, the network side can also broadcast the information in a multicast or unicast manner. , and send the load level information to the terminal.

Step 202, selecting an access policy corresponding to the business service level information and the load level information from the preset access policy set;

After the terminal obtains its own business service level information and the high or low load status of the network side, it can select an access strategy corresponding to this access process according to the two status information. Specifically, in this embodiment, a variety of different access policies can be set correspondingly on the terminal side according to certain access parameters and access algorithms, and according to different combinations of various states of the terminal and the network. The strategy includes information such as different initial access window sizes, access backoff window algorithms, and access time delays formed according to a certain access algorithm. After multiple access strategies are set, the set multiple access strategies are combined into an Access Strategy Set (Access Strategy Set) on the terminal side. Each access strategy in the access strategy set is related to a certain terminal service The service level corresponds to the network load status, which is equivalent to a two-input-one-output mapping list. After the terminal knows its own business service level information and the load status of the access network, it can query and select the corresponding access policy from the preset access policy set, and the selected access policy A reasonable access strategy that conforms to the current terminal and network conditions.

At the same time, the terminal's determination of the access policy can also be calculated by the terminal according to a preset access algorithm. Specifically, in this embodiment, an access algorithm that can calculate the terminal access strategy can also be preset on the terminal side. The access algorithm is equivalent to a calculation function with two inputs and one output. The terminal determines its own After the business service level information and the load status of the network side are determined, the business service level information and network load level information are used as the input conditions of the preset access algorithm, and the access strategy of this access process can be calculated , and similarly, the calculated access policy is also a reasonable access policy conforming to the current terminal and network conditions.

Optimally, during the terminal's network access process, for the terminal, its influencing factors on the entire network access process include not only the service level corresponding to the service to be accessed, but also the corresponding service level of the user of the terminal. User level, that is, when the terminal selects or calculates the access strategy, if the terminal corresponds to different user priority levels, the specific strategy for the terminal to access the network can also be different accordingly, so as to ensure that users with high priority levels can access the network in advance. into the network.

Therefore, in this embodiment, the selection of the access strategy in this step can also be selected by the terminal according to the service level of the service to be accessed, the current load level of the network side, and the user level corresponding to itself. The preset access strategy and the corresponding selection are obtained, or are calculated according to the preset access algorithm. Correspondingly, a plurality of different access policies corresponding to different combinations of business service levels, user levels, and network load levels are set in the preset access policy set at this time, which is equivalent to a three-input and one-output Or, the preset access algorithm at this time also forms a calculation function equivalent to three inputs and one output in order to consider the influence of the terminal user level on the access strategy. Information can be queried and selected from the preset access strategy set, or the corresponding access strategy can be selected according to the preset access algorithm, and the three determined information can be used as the input conditions of the access algorithm to calculate Obtain the corresponding access policy. The access strategy selected at this time is a reasonable access strategy that conforms to the service level of the terminal, the user level, and the load level of the network.

Step 203, access to the corresponding network according to the selected access strategy.

After selecting the corresponding access strategy according to the above steps, the terminal can access the corresponding network through the corresponding base station according to the selected access strategy. In this embodiment, since the selected access strategy fully considers the characteristic state of the terminal itself and the current real-time load state of the network side, the terminal accesses the network according to the access strategy, and can follow the current load state of the network. Making full use of the current network resources can avoid the situation that the terminals that should be allowed to access the network on the network side fail to access the network in time due to the ineffective use of resources on the network side. Furthermore, since the selection and control of the access strategy in this embodiment are performed on the terminal side, even if there are a large number of terminals performing the network access process at the same time, since the base station does not need to control the access of the terminals, it greatly reduces the The processing burden of the base station accelerates the network access process of the terminal.

In the terminal access method of this embodiment, during the process of terminal access to the network, the terminal itself selects the corresponding Access strategy, so that the selected access strategy can fully consider the influence of the network side on the access process, so that when the terminal performs network access operations according to the selected access strategy, it can timely and fully use the resources on the network side Further, since the control of the access process in the embodiment of the present invention is performed on the terminal side, the processing burden of the base station when a large number of terminals are connected is also reduced, and the process of terminal access is accelerated.
