Description

Network searching method and device

Technical field

The present invention relates to the field of communications, and in particular, to a network search method and apparatus.

Background technique

When the user uses China Telecom's 4th Generation mobile communication technology (4th Generation Mobile Communication Technology) mobile phone, when the LTE (Long Term Evolution) signal is poor, the mobile phone will fall back to CDMA 1X/EV-DO. On the network, when the LTE signal is restored, the mobile phone often takes a long time to return to the LTE. In particular, when the CDMA (Code Division Multiple Access) network fails to correctly configure the LTE neighboring cell, the mobile phone needs to take a few minutes. The time will trigger the automatic search for LTE.

Since the CDMA system belongs to the 3GPP2 (3rd Generation Partnership Project 2) protocol camp, the behavior of the search network in this camp is automatically controlled by the PRL (Preferred Roaming List), and the user cannot intervene. . LTE/WCDMA (Wideband Code Division Multiple Access) belongs to the 3GPP camp, and 3GPP can perform manual search to allow users to select the network type and carrier.

With the development of smart phones, the current CDMA/LTE/WCDMA/GSM (Global System for Mobile Communication) full-mode supports more and more mobile phones. It can be said that such products are integrated with 3GPP (3rd Generation). Partnership Project, 3rd Generation Partnership Project) and 3GPP2 camp products. However, due to long-term technical isolation and differences between 3GPP2 and 3GPP, CDMA 1X/EV-DO represented by 3GPP2 does not provide users with the function of manual search.

detailed description

In order to solve the problem of the prior art that the 3GPP2 network cannot be searched for in the 3GPP2 mode, the present invention provides a network search method and apparatus. The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It is understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Example 1

This embodiment provides a network search method, which can be applied to the terminal side. FIG. 1 is a flowchart of a network search method according to Embodiment 1 of the present invention. As shown in FIG. 1, the method includes the following steps:

Step 101: After knowing that the user has the requirement of manually searching for the network, setting the terminal to the 3GPP mode;

Specifically, in this embodiment, a function menu that allows the user to manually search for the 3GPP standard can be specified in the 3GPP2 system. After the user selects the function menu, the terminal learns the operation of the manual search network performed by the user, and then learns The user has the need to manually search the network and set the terminal to the 3GPP mode.

In the actual application, after knowing that the user has the requirement of manually searching the network, it may first determine whether the terminal is currently registered in the 3GPP2 format, and if so, set the terminal to the 3GPP mode, and if not, directly perform the process according to the 3GPP search network. The steps to search the network.

Step 102: Search for a network of the 3GPP standard in the 3GPP mode;

This step 102 can be specifically performed as follows:

The 3GPP network standard supported by the terminal is learned; the search is performed according to the priority of each network standard until the network is searched.

Step 103: Provide the user with the search result of the 3GPP standard network.

During the execution of step 102, if a network of the corresponding system is searched, a list of all networks of the system is provided to the user.

Based on the foregoing steps 101 to 103, the foregoing method may further include:

After providing the user with the search result of the 3GPP standard network, determining whether the user selects the network in the search result within the preset time period; if yes, registering the terminal to the network selected by the user; if not, determining the search In the case where the network in the result is higher than the system of the network used before the terminal, the terminal is registered on the network with the highest standard in the search results.

In one step, the method may further include:

Before setting the terminal to the 3GPP mode, it is determined whether the network currently registered by the terminal is a 3GPP2 standard, and if so, the terminal is set to the 3GPP mode after the service of the 3GPP2 system is disabled.

Example 2

This embodiment further describes the network search method provided by the present invention by disclosing more technical details. FIG. 2 is a flowchart of a network search method according to Embodiment 2 of the present invention. As shown in FIG. 2, the method may specifically Including the following operations:

Step 1: The user performs a manual search for the network. The mobile phone determines whether the current registration is a 3GPP2 standard network. If the current registration is not the 3GPP2 standard, the mobile network can be manually searched according to the standard procedure specified by the 3GPP. Registered in 3GPP2 format, then proceed to step 2.

Step 2: The mobile phone temporarily leaves the service from the 3GPP2 network, enters the 3GPP mode, searches the network according to the 3GPP standard procedure, and returns the search result. If the search result is empty, the empty list is returned, and the mobile phone automatically enters the 3GPP2 mode again. , return to the previous CDMA network, if the return list is not empty, proceed to step 3, the detailed search process is shown in Figure 3:

Step 2a: According to FIG. 3, the mobile phone enters the manual network selection mode, but unlike the existing 3GPP TS 23.122 solution, the present embodiment uses the priority search system according to the priority of the system and returns the search result. the way. The mobile phone in 3GPP TS 23.122 needs to search all the systems and all networks supported by itself, and returns a list of all the networks that have been searched for their own support. Due to the increasing frequency bands and formats supported by mobile phones, carrier networks are becoming more and more complex, often causing manual search to take a few minutes to return results, and it is also prone to search deadlocks, even to the middle of the network. The process has gone wrong. In this embodiment, the network system searches for each network standard in the order of priority of each network standard. For example, the LTE network is searched first, and after searching for the LTE network, the search result is returned immediately, that is, the list of the LTE network, so that the The user's usage habits provide users with a higher rate network standard.

The specific way to search the network is as follows:

Step 2b: The mobile phone sets its working mode to LTE mode, searches for the LTE network, and when searching for an optional PLMN (Public Land Mobile Network) that is excellent in signal and can reside (including HPLMN, HPLMN (home) The public land mobile network (original public land mobile (telephone) network), belonging to the public land mobile network, OPLMN (Operator Controlled PLMN operator control PLMN), immediately returns to all available LTE network list, proceeds to step 3.

Step 2c: When the useful LTE network cannot be searched in step 2b, the mobile phone sets its own working mode to WCDMA mode, searches for the WCDMA network, when the search for the signal is good and the optional PLMN can be camped on (including HPLMN, EHPLMN, OPLMN), immediately return to the list of all available WCDMA networks, go to step 3.

Step 2d: When step 2c cannot search for a useful WCDMA network, the mobile phone sets its own working mode to GSM mode, searches for the GSM network, and when searching for an optional PLMN with good signal and can reside (including HPLMN, EHPLMN, OPLMN) ), immediately return to the list of all available GSM networks, go to step 3 for the user to choose.

Step 3: When the search process described in FIG. 3 searches for an available 3GPP network, the user is returned to a network list, and the user can manually select any one of the entries. If the user does not select within a preset time, the mobile phone prioritizes all the currently searched networks with the previously served CDMA network. If a current 3GPP network has a higher priority than the CDMA network, the mobile device automatically registers with this. 3GPP network, otherwise return to CDMA network. Then the search list disappears automatically and the user's mobile phone enters the normal service state.
