Description
Technical Field
The invention relates to the technical field of communication, in particular to a method, a device and a system for a mobile terminal to rapidly reside in an AP cell.
Background
With the explosion of Internet services and the wide application of broadband access networks and wireless networks, high-speed, convenient and fast access to networks is gaining wide attention. Users need to enjoy wireless data services using handheld wireless devices at high speed, convenience, and low cost. Meanwhile, in order to better utilize resources of the existing network and better protect the cost of network equipment operators, a subminiature mobile phone base station equipment FEMTO-CELL is introduced into the wireless Access network, and the corresponding network equipment is called an Access Point (AP).
Fig. 1 shows a network topology after an AP device is introduced into an existing UMTS network, which takes a Universal Mobile Telecommunications System (UMTS) as a wireless access System, and illustrates an application of the AP device. The AP directly goes out of the Gi interface and can directly access the Internet, so that the impact of high-speed data service on a mobile network is greatly reduced, and the existing wireless network can access more wireless high-speed data users. The introduction of the AP also solves the bottleneck problem of air interface resources of the wireless data service, and high-speed data service users in the macro cell are distributed.
The inventor finds that the AP is generally deployed in the home of the user, and the AP cell and the macro cell form the same coverage relationship in the process of implementing the present invention. The positional relationship between the AP cell and the macro cell is uncertain, and may be in the middle of the macro cell or at the edge of the macro cell. The positional relationship is shown in fig. 2.
When a user returns home, it is desirable to be able to automatically reselect/switch from the macro cell to within the range of the AP cell, reducing the burden on the macro cell while enjoying better service. To do this, the macro cell needs to give a detailed measurement instruction including the AP cell, but since the AP device automatically configures and autonomously selects scrambling resources, and the installation, use, and deactivation of the AP device are also user behaviors, an operator cannot give an accurate neighbor relation in the macro cell, and thus, the current user cannot normally reselect/switch to the AP cell.

The scheme of the first embodiment of the invention overcomes the energy consumption caused by blind search of the AP cell by the mobile terminal by sending the associated AP information and the parameters to the mobile terminal, and realizes the rapid residence of the AP cell by the mobile terminal.
An embodiment of the present invention provides a method for a mobile terminal to quickly camp on an AP cell, as shown in fig. 4, including the following steps:
step 1: the mobile terminal receives the associated AP information and parameters;
the AP information and parameters include: the method comprises the following steps of AP cell information, parameters of the AP cell participating in cell reselection, adjacent macro cell information of the AP cell and measurement starting parameters. The explanation of each information is the same as that of the first embodiment, and is not repeated here.
The AP information and parameters may be requested from the assisted reselection/handover server or actively transmitted by the assisted reselection/handover server for acquisition. The AP cell information and the neighboring macro cell information of the AP cell may be actively sent to an assisted reselection/handover server by the AP; the parameters of the AP cell participating in cell reselection, the adjacent macro cell information of the AP cell and the measurement starting parameters can be configured for the AP by an auxiliary reselection/switching server; the association relationship between the mobile terminal and the AP cell is configured by the auxiliary reselection/switching server. The neighboring macro cell information and the measurement start parameter of the AP cell may be sent to the mobile terminal together with the AP cell information and the parameter of the AP cell participating in cell reselection, or may be sent separately.
The auxiliary reselection/switching server can send the AP information and parameters through a short message in an SIM data download mode. The short message content starts with APCELL, if the short message content only contains APCELL, the short message content indicates that the mobile terminal is required to delete the relevant AP information and parameters stored by the mobile terminal, otherwise, the short message content indicates that the mobile terminal is required to update the relevant AP information and parameters stored by the mobile terminal. That is, if the mobile terminal does not have an associated AP cell, the short message sent by the assisted reselection/handover server only includes "APCELL", and at this time, the mobile terminal deletes the stored AP information and parameters.
Step 2: the mobile terminal stores the AP information and the parameters;
after receiving the short message sent by the auxiliary reselection/switching server in the SIM data download manner, the mobile terminal processes the AP information and parameters according to the content of the short message, for example, if the content of the short message only includes "APCELL", the mobile terminal deletes the relevant AP information and parameters stored by itself, otherwise, the mobile terminal updates the relevant AP information and parameters stored by itself.
The mobile terminal can forward the AP information and the parameters to the memory card for storage through an SIM data download mode of the ENVELOPE COMMAND, the memory card updates the AP information and the parameters of the memory card according to the information forwarded by the mobile terminal, and sends the stored information to the mobile terminal when the mobile terminal needs, and the mobile terminal writes the measurement starting parameters into a physical layer as a basis for starting measurement. The memory card can inform the mobile terminal to update or delete and store the AP information and parameters through the newly added Proactive UICC command. The format of the Proactive UICC command for deleting and updating the mobile terminal AP Cell related information is as follows, the Text string of the command Update AP Cell Info for updating the AP Cell information carries the information of the AP Cell to be stored, the neighboring macro Cell information of the AP Cell, and the measurement start parameter.

And step 3: the mobile terminal judges whether the current service cell is an adjacent macro cell of the AP cell;
when the mobile terminal enters a cell in an idle state or is started to reside in a process processing system message SIB11 or SIB11bis of the cell, or when the mobile terminal enters a new cell process processing system message SIB12 in a connected state, whether the current serving cell is an adjacent macro cell of the AP cell is judged;
the mobile terminal can judge whether the current service cell is the adjacent macro cell of the AP cell according to the received AP cell adjacent macro cell information.
If yes, executing step 4; otherwise, processing according to the existing standard mode;
and 4, step 4: the mobile terminal informs the AP to start radio frequency, writes the AP cell information and parameters into a physical layer measurement monitoring set, and measures the AP cell;
once the mobile terminal enters the adjacent macro cell of the AP cell, the mobile terminal sends a short message to the short message server, the short message server forwards the short message to the access gateway AG, and the AG controls the AP to start a radio frequency; and once the mobile terminal leaves the adjacent macro cell of the AP cell, the mobile terminal sends a short message to the short message server, the short message server forwards the short message to the AG, the AG controls the AP and closes the AP radio frequency.
When the measurement result of the AP cell satisfies a predetermined condition, step 5 is executed, for example, when the signal quality of the AP cell is better than the signal quality of the current serving cell and a parameter for the AP cell to participate in cell reselection is satisfied, step 5 is executed; otherwise, continuing to reside in the existing cell;
the measurement of the AP cell is performed if the measurement initiation parameter is satisfied.
And 5: the mobile terminal enters the AP cell through switching or cell reselection;
step 6: receiving frequency, scrambling code, location indication and/or greeting and the like of the AP cell sent by the AP, for example, welcoming the user to use the greeting and the like information of the AP service;
once the mobile terminal successfully resides in the AP cell through the measurement, the AP may notify the mobile terminal of information such as frequency, scrambling code, location indication and/or greeting of the AP cell in a short message manner, and may also include information of the neighboring macro cell of the AP cell in the short message.
In the embodiment of the invention, the associated AP information and the associated parameters are sent to the mobile terminal, so that the energy consumption caused by blind search of the AP cell by the mobile terminal is overcome, and the mobile terminal realizes fast residence of the AP cell by measuring the associated AP cell.
In addition, the mobile terminal can control the opening and closing of the AP radio frequency in a short message mode according to the actual situation, and the energy consumption of the AP can be effectively saved.
In summary, the embodiment of the present invention realizes that the mobile terminal resides in the AP cell quickly, thereby saving the energy consumption problem caused by blind search of the AP cell, and the mobile terminal controls the AP to be turned on and off by a short message according to the actual situation, thereby effectively saving the energy consumption of the AP.
