Definitions
- the present invention relates to mobile communication technology, and particularly to a method for establishing a service connection. Background of the invention
- wireless networks with multiple access technologies have emerged, such as the Global System for Mobile Communications (GSM), Code Division Multiple Access (CDMA) in the second generation of mobile communications, and broadband in the third generation of mobile communications.
- Code Division Multiple Access (WCDMA) Code Division Multiple Access
- CDMA2000 network.
- the user equipment (UE) After the user equipment (UE) is powered on, it needs to select a certain network to camp on in a suitable cell, and in an idle state, it needs to listen to the system messages and paging messages of the cell, so as to be able to initiate a certain Service requests and receive service requests from other UEs.
- the user terminal may be a single-mode or multi-mode terminal.
- a user terminal initiates a service request, and a process of establishing a service connection is:
- the UE initiates a service request to a network side (step 101); when the network side receives the service request, the network side judges Whether the service can be provided, and if it can be provided, establish a service connection with the network side; otherwise, the service request fails (step 102).
- the UE After the UE is powered on, it will select a suitable PLM N 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. In addition, after the UE camps on a suitable cell, in the idle state, it can periodically initiate cell reselection based on the signals of other cells monitored to camp on a more suitable cell. Of course, it is also possible to reselect a cell of the PLMN network for camping. In the process of PLMN selection / reselection, cell selection / cell reselection, the cell with the best signal is always selected for camping.
- the UE when the UE needs to request a certain service, if the user terminal does not consider whether the cell's affiliated network is capable of the requested service, it initiates a service request in the currently camping cell, and camps on the cell with the best monitored signal. If the cell-affiliated network cannot provide the service requested by the UE, even if the UE actually applies for the service, the network on which the UE resides will reject the service request initiated by it. Therefore, in the prior art, a method in which a user initiates a service request and establishes a service connection has a high possibility of service failure and a low access rate of the user terminal, which causes dissatisfaction of the user. Summary of the invention
- an object of the present invention is to provide a method for establishing a service connection so as to enhance the access rate of a user terminal.
- the present invention provides a method for establishing a service connection.
- the method includes:
- the user terminal sends a service request to the cell and establishes a service connection with the cell.
- the cell supporting the service to be initiated in step A is selected by the user terminal according to the pre-built conditions of the user saved by itself.
- the prefabrication conditions may be set according to a sequence of tariffs, service quality, signal quality, or prefabrication conditions.
- the service cell to be initiated in step A is the user terminal's manual trigger selection based on the user.
- Step A can include:
- the user terminal searches all the cells in the current coverage area, and determines whether there is a cell that can provide the service to be initiated. If it does not exist, the process is skipped, and if it exists, execute Step A12;
- A13 Determine whether the cell is currently camped. If not, perform cell reselection and stay in the reselected cell, and then perform step B. Otherwise, perform step B.
- Step A can include:
- the user terminal determines whether the currently camping cell can provide the service to be initiated, and if so, performs step B, otherwise, performs step A22;
- step A22 The user terminal searches for a cell in the current coverage area, and determines whether there is a cell that can provide the service. If so, step A23 is performed; otherwise, the process is skipped.
- the user terminal determines whether there is only one cell that can provide the service, and if so, performs cell reselection and camps on the reselected cell, and then performs step B, otherwise, displays a cell list and performs step A24;
- the user terminal 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 camps on the cell selected by the user.
- Step A can include:
- step A31 The user terminal searches all cells in the current coverage area to determine whether there is a cell that can provide the service. If it does not exist, the user terminal skips this process. Otherwise, step A32 is performed.
- the user terminal determines whether there are more than one cell, and if so, displays a list of cells that can provide the service, and performs step A33, otherwise, performs step A34;
- the user terminal After receiving the information of the user selecting the 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 currently camped. If not, perform cell reselection, select the cell to camp, and then perform step B. If yes, perform step B directly.
- the UE when the UE is in an idle state, the UE has Selectively initiate a cell reselection process to camp on a suitable cell, and then initiate a corresponding service request. And before the UE initiates a service request to the network, it first determines 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, while greatly improving the service connection rate and service quality, and enhancing user satisfaction.
- selecting a cell includes two manual and automatic selection methods.
- the user terminal selects the cell that best meets the user's needs from the list of cells that meet the pre-conditions, which greatly meets the interests of the user.
- the entire selection process is obscure to the user, and the user ’s feeling is consistent with the initiation of the service in the current cell, so that the user does not need to care whether the cell where the mobile phone currently resides can provide the initiated service.
- Automatic search by mobile phone brings great convenience to users.
- manual selection is adopted, the user can select his favorite cell from the list of cells that satisfy the service. At this time, the user's requirements can be met to the greatest extent.

- FIG. 4 is a schematic flowchart of a third embodiment for implementing the method of the present invention. Mode of Carrying Out the Invention
- the core content of the present invention is: in an idle state, the user terminal selects and resides in a cell that can support the service to be initiated; and then sends a service dependency to the cell and establishes a service connection with the cell.
- the user terminal may select a cell in two modes, namely, an automatic and a manual selection mode.
- the automatic selection method is that the user terminal directly selects a cell again according to the prefabricated condition and the currently searched cell;
- the manual selection is that the user terminal obtains a 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 performs cell reselection according to the cell information selected and triggered by the user.
- user prefabricated conditions can be set in the user terminal, including service types and 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 ranking of cells in a certain list.
- service types and 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 ranking of cells in a certain list.
- the user terminal 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 condition, and camps on a network that can provide the service and meets the preset condition of the user. Then send a business request to the resident network.
- the manual selection method is adopted, the user can arbitrarily select a cell according to his own needs.
- Step 201 The UE searches all cells in the current coverage area to determine whether there is a cell that can provide the service to be initiated. If it does not exist, step 205 is performed, and if it exists, step 202 is performed;
- Step 202 The UE determines whether the number of cells that can provide the service exceeds one. If there is more than one, it selects a qualified cell for camping based on user preset conditions, such as optimal tariff, optimal service quality, and optimal signal quality. Or prioritize by a list, then Go to step 204, if there is only one cell, go to step 203;
- Step 203 The UE determines whether the cell is currently camped, and if not, performs cell reselection, selects the cell to camp, and then performs step 204, and if so, directly performs step 204;
- Step 204 The UE initiates a service request to the network side, establishes a service connection with the network side, and ends this process.
- Step 205 The service request fails, and the process ends.
- the UE when the UE is in an idle state, the UE selectively initiates a cell reselection process according to the initiated service and the preset conditions of the user to camp on the appropriate cell, and then initiates the corresponding cell.
- Business request This embodiment selects a cell that best meets the user's needs from the list of cells that meets the pre-conditions, which greatly conforms to the interests of the user.
- the UE initiates a service request to the network it first determines whether the current cell can provide the service initiated by the UE. If the network cannot provide the service, the service request will not be sent to the current cell, which greatly reduces the processing load of the current network and greatly Improved business connection rate and service quality.
- a service request is initiated to the network to establish a service connection.
- the whole process is shielded to the user, and the user ’s feeling is consistent with the initiation of the service in the current cell. In this way, the user does not need to worry about whether the cell where the mobile phone currently resides can provide the initiated service, and the mobile phone automatically searches for it. Users bring great convenience.
- Step 301 The UE determines whether the current cell can provide the service initiated by the UE, and if it can provide, then step 305 is performed, and if it cannot be provided, step 302 is performed;
- Step 302 The UE searches for other cells in the current coverage area to determine whether there is a cell capable of providing the service, and if so, performs step 303; otherwise, performs step 306;
- Step 303 The UE determines whether the cell that can provide the service has only one cell, and if so, performs cell reselection, selects the cell for camping, and performs step 305. If there is more than one cell, it may be displayed according to conditions set by the user The cell list is provided to the user to trigger selection, and step 304 is performed;
- Step 304 The UE receives the corresponding cell selected by the user trigger, performs cell reselection according to the cell triggered by the user, and camps on the selected cell triggered by the user;
- 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 the process ends.
- Step 401 UE searches for all cells in the current coverage area, determines whether the cell to provide the service exists, if not, step 406 is executed, otherwise, step 402.
- Step 402 The UE determines whether there is more than one cell, and if so, executes step 404, otherwise, executes step 403.
- Step 403 The UE determines whether the cell is the current camping cell, and if not, performs cell reselection, selects the cell for camping, and then performs step 405, and if so, performs step 405.
- Step 404 The UE displays a cell list for the user to select; the user may trigger the selection of the corresponding cell in the list according to related factors, such as tariffs, operator service quality, etc., the UE performs cell reselection according to the user's trigger selection, and selects the user trigger The selected cell camps, and step 405 is performed.
- the UE may sort the cells according to a condition preset 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 the process ends.
- the second embodiment and the third embodiment are cases where the user manually triggers the selection of a cell.
- the UE When the UE initiates a service debt request, according to the type of service requested, the UE selectively reinitiates a cell reselection, selects an appropriate cell to camp on, and sends it. Business request.
- a cell list may be displayed for a user to trigger selection of a cell. The difference between the two lies in: In the second embodiment, it is first determined whether the cell in which the user terminal currently resides can provide the service to be initiated, and if it is satisfied, the cell reselection is not performed, and a service request is directly initiated.
- the third embodiment is to first search whether there is a cell that can provide the service to be initiated among all the cells in the current coverage area. If not, the service request will not be initiated. However, 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. Therefore, the service connection rate and service quality are greatly improved, which will bring great convenience to wireless users. Not initiating a service to a cell that cannot provide the service it requested greatly reduces the processing load of the current network. Of course, the user can also select his favorite cell from the list of cells that satisfy the service, and meet the user's requirements to the greatest extent.
