Abstract

The invention discloses a method for establishing a service connection. In the method, when the user terminal is idle, the user terminal selectively initiates a cell reselection process to reside in a suitable cell, and then initiates a corresponding service request. And before the user terminal initiates a service request to the network, it first judges whether the current cell can provide the service initiated by the user terminal. If the network cannot provide the service, it will not send the service request to the current cell, and then send the service request to the cell where the network resides. Initiate a service request and establish a service connection. This method greatly reduces the processing load of the current network, and at the same time greatly improves the service connection rate and service quality, and enhances user satisfaction.

Description

A method of establishing a business connection

technical field

The invention relates to mobile communication technology, in particular to a method for establishing service connection.

Background technique

With the development of wireless technology, wireless networks of multiple access technologies have emerged, such as GSM and CDMA in the second generation of mobile communication and WCDMA and CDMA2000 in the third generation of mobile communication. In this case, after the user equipment (UE) is turned on, it needs to select a certain network to camp in a suitable cell, and needs to monitor the system message and paging message of the cell in the idle state, so as to initiate a certain Service requests and receiving service requests from other UEs. Here, the user terminal may be a single-mode or multi-mode terminal.

Referring to Fig. 1, in the prior art, the user terminal initiates a service request, and the process of establishing a service connection is: UE initiates a service request to the network side (step 101); after the network side receives the service request, the network side judges Whether the service can be provided, if it can be provided, establish a service connection with the network side, otherwise, the service request fails (step 102).

At present, after the UE is turned on, it will select a suitable PLMN network according to the list of available PLMNs maintained by itself, and then camp on a suitable cell where the PLMN network is located, and register location area information. Moreover, after the UE camps on a suitable cell, it can periodically initiate cell reselection to camp on a more suitable cell according to the monitored signals of other cells in the idle state. Of course, it is also possible to reselect a cell of the PLMN network to camp on. During the process of PLMN selection/reselection and cell selection/cell reselection, the cell with the best monitored signal is always selected for camping.

However, when the UE needs to request a certain service, if the user terminal does not consider whether the network of the cell is capable of the requested service, it initiates a service request in the cell it is currently camping on, and camps on the cell with the best signal detected. , if the network to which the cell belongs cannot provide the service requested by the UE, even if the UE actually applies for the service, the network where the UE resides will reject the service request initiated by it. Therefore, the method in the prior art where a user initiates a service request and establishes a service connection has a high possibility of service failure, and the access rate of the user terminal is low, which causes dissatisfaction of the user.

Contents of the invention

In view of this, the purpose of the present invention is to provide three methods for establishing service connections, so as to enhance the access rate of user terminals.

In order to achieve the above object, a method for establishing a service connection provided by the present invention includes:

A11. The user terminal searches all the cells in the current coverage area, and judges whether there is a cell that can provide the service to be initiated. If it does not exist, then jump out of this process. If it exists, execute step A12;

A12. Determine whether the number of cells that can provide the service exceeds one, if so, select a cell to reside in, and execute step B, otherwise, execute step A13;

A13. Determine whether the cell is the cell where the cell is currently residing, if not, perform cell reselection, and reside in the reselected cell, and then perform step B, otherwise, perform step B;

B. The user terminal sends a service request to the cell, and establishes a service connection with the cell.

Wherein, selecting a cell to camp on from the cells that can provide the service in step A12 is: the user terminal selects a cell to camp on from the cells that can provide the service according to the prefabricated conditions of the user saved by itself.

The prefabricated conditions are set according to the sequence of tariff, service quality, signal quality or prefabricated conditions.

Another method for establishing a service connection provided by the present invention includes:

A21. The user terminal judges whether the cell where it currently resides can provide the service to be initiated, and if so, execute step B, otherwise, execute step A22;

A22, the user terminal searches for the cells in the current coverage area, and judges whether there is a cell that can provide the service, if it exists, then execute step A23, otherwise, jump out of this process;

A23, the user terminal judges whether there is only one cell that can provide the service, if yes, then perform cell reselection, and reside in the reselected cell, and then perform step B, otherwise, display the cell list, and perform step A24;

A24. After receiving the cell information selected by the user according to the displayed cell list, the user terminal performs cell reselection according to the cell information selected by the user, and resides in the cell selected by the user;

B. The user terminal sends a service request to the cell, and establishes a service connection with the cell.

Another method for establishing a service connection provided by the present invention includes:

A31, the user terminal searches all the cells in the current coverage area, and judges whether there is a cell that can provide the service, if not, then jump out of this process, otherwise, execute step A32;

A32, the user terminal judges whether there is more than one sub-district, and if so, displays a list of sub-districts that can provide the service, and executes step A33, otherwise, executes step A34;

A33. After receiving the information that the user selects a cell triggered by the cell list, the user terminal performs cell reselection according to the user's selection, and resides in the reselected cell, and then performs step B;

A34. Determine whether the cell is the current resident cell, if not, perform cell reselection, select the cell to reside in, and then perform step B, if yes, directly perform step B;

B. The user terminal sends a service request to the cell, and establishes a service connection with the cell.

It can be seen from the above process that in the method of the present invention, when the UE is idle, the UE selectively initiates a cell reselection process to camp on a suitable cell, and then initiates a corresponding service request. And before the UE initiates a service request to the network, it first judges whether the current cell can provide the service initiated by the UE. If the network cannot provide the service, it will not send a service request to the current cell, and then initiate a service request to the network to establish a service connection . This method greatly reduces the processing load of the current network, and at the same time greatly improves the service connection rate and service quality, and enhances user satisfaction.

Moreover, selecting a cell includes two selection methods, manual and automatic. In the automatic selection mode, the user terminal selects the cell that best meets the user's needs from the list of cells that meet the preconditions, which greatly meets the interests of the user. For the automatic mode, the entire selection process is shielded for the user, and the user's feeling is consistent with initiating services in the current cell, so that the user himself does not need to care whether the cell where the mobile phone is currently residing can provide the initiated service. Automatic search by mobile phone brings great convenience to users. When using the manual selection method, the user can select his favorite cell from the cell list that meets the service requirements, and at this time, the requirements of the user can be satisfied to the greatest extent.

Detailed ways

In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

The core content of the present invention is: in the idle state, the user terminal selects and resides in a cell that can support the service to be initiated; then sends a service request to the cell and establishes a service connection with the cell.

Here, the user terminal may select a cell in two ways, that is, automatic and manual selection. The automatic selection method is that the user terminal reselects a cell directly according to the prefabricated conditions and the currently searched cell; the manual selection is that the user terminal obtains the cell list according to the prefabricated condition and the currently searched cell, and provides the cell list to the user. Trigger selection is performed, and the user terminal then performs cell reselection according to the cell information triggered by the user.

In the actual application process, when the automatic selection method is adopted, user prefabricated conditions can be set in the user terminal, including the service type and the prefabricated conditions corresponding to each service required by the user, such as optimal tariff, optimal service quality, and signal quality. Conditions such as optimal or prioritization of cells according to a certain list. When the user terminal initiates a service request, the user terminal selectively re-initiates cell reselection according to the service type corresponding to the service request and the preset conditions, and resides in the network that can provide the service and best meet the user's preset conditions. Then send a service request to the resident network. When the manual selection method is adopted, the user can select a cell arbitrarily according to his own needs.

The technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

As shown in Figure 2, when the UE is in an idle state and initiates a service request, the following processes need to be completed:

Step 201: UE searches all the cells in the current coverage area, and judges whether there is a cell that can provide the service to be initiated, if not, execute step 205, and if yes, execute step 202;

Step 202: The UE judges whether the number of cells that can provide the service exceeds one, and if more than one, select a qualified cell to camp on according to user preset conditions, such as optimal tariff, optimal service quality, and optimal signal quality Or arrange the order of priority according to a certain list, and then perform step 204, if there is only one cell, perform step 203;

Step 203: UE judges whether the cell is the current cell to reside on, if not, performs cell reselection, selects the cell to camp on, and then executes step 204, if yes, directly executes step 204;

Step 204: The UE initiates a service request to the network side, and establishes a service connection with the network side, and ends this process.

Step 205: The service request fails, and this process ends.

It can be seen from the above process that in Embodiment 1, when the UE is in an idle state, the UE selectively initiates a cell reselection process according to the initiated service and user preset conditions to camp on a suitable cell, and then initiates a corresponding business request. In this embodiment, the cell that best meets the needs of the user is selected from the list of cells satisfying the precondition, which greatly conforms to the interests of the user. And before the UE initiates a service request to the network, it first judges whether the current cell can provide the service initiated by the UE. If the network cannot provide the service, it will not send the service request to the current cell, which greatly reduces the processing load of the current network and greatly The service completion rate and service quality are improved. After cell reselection triggered by the service, a service request is initiated to the network and a service connection is established. The whole process is shielded for the user, and the user's feeling is consistent with initiating services in the current cell, so that the user himself does not need to care whether the cell where the mobile phone is currently residing can provide the initiated service, but the mobile phone automatically searches and gives It brings great convenience to users.

The technical solution of the present invention will be further described by citing specific embodiment 2 below.

Referring to Figure 3, in this embodiment, when the UE is in an idle state and initiates a service request, the following processes need to be completed:

Step 301: The UE judges whether the current cell can provide the service initiated by the UE, if it can provide it, execute step 305, if not, execute step 302;

Step 302: The UE searches for other cells in the current coverage area, and judges whether there is a cell that can provide the service, and if so, executes step 303, otherwise, executes step 306;

Step 303: The UE judges whether there is only one cell that can provide the service. If so, perform cell reselection, select this cell for camping, and then perform step 305. If there is more than one cell, it can be displayed according to the conditions set by the user. The cell list is provided to the user to trigger selection, and step 304 is executed;

Step 304: The UE receives the corresponding cell selected by the user trigger, performs cell reselection according to the cell selected by the user trigger, and camps on the cell selected by the user trigger;

Step 305: The UE initiates a service request to the network, establishes a service connection with the network, and ends this process.

Step 306: The service request fails, and this process ends.

As shown in Figure 4, in this embodiment, when the UE is in an idle state and initiates a service request, the following processes need to be completed:

Step 401: The UE searches all cells in the current coverage area, and judges whether there is a cell that can provide the service, and if not, executes step 406; otherwise, executes step 402.

Step 402: The UE judges whether there is more than one cell, and if so, executes step 404; otherwise, executes step 403.

Step 403: UE judges whether the cell is currently camped on, if not, performs cell reselection, selects the cell to camp on, and executes step 405, if yes, executes step 405.

Step 404: The UE displays a list of cells for the user to select; the user can trigger the selection of the corresponding cell in the list according to relevant factors, such as tariffs, service quality of the operator, etc., and the UE performs cell reselection according to the user's trigger selection, and selects the cell triggered by the user. The selected cell is camped on, and then step 405 is performed. Here, the UE may sort the cells according to the preset conditions set by the user.

Step 405: The UE initiates a service request to the network, establishes a service connection with the network, and ends this process.

Step 406: The service request fails, and this process ends.

Embodiment 2 and Embodiment 3 are both cases where the user manually triggers the selection of a cell. When the UE initiates a service request, according to the requested service type, the UE selectively re-initiates cell reselection, and selects a suitable cell to reside in before sending the service. ask. Moreover, if there are multiple suitable cells at the same time, a cell list may be displayed for the user to trigger selection of a cell. The difference between the two is that in the second embodiment, it is first judged whether the cell where the user terminal currently resides can provide the service to be initiated, and if it is satisfied, the cell reselection is not performed, and the service request is directly initiated. In the third embodiment, it is firstly searched whether there is a cell that can provide the service to be initiated among all the cells in the current coverage area, and if not, the service request will not be initiated. But no matter what steps are taken first, it is to ensure that the cell where the user terminal initiates the service request can support the service to be initiated, so the service completion rate and service quality are greatly improved, which will bring great convenience to wireless users. At the same time, the UE Not initiating a service to a cell that cannot provide the requested service greatly reduces the processing load of the current network. Of course, users can also choose their favorite cells from the list of cells that satisfy the service, so as to meet the user's requirements to the greatest extent.

In a word, the above descriptions are only preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention.
