Description

Cell registration method and device

Technical Field

The present application relates to the field of electronic technologies, and in particular, to a cell registration method and apparatus.

Background

The long Term Evolution (L ong Term Evolution, L TE) is a long Term Evolution of UMTS (Universal mobile telecommunications System) technical standard organized by 3GPP (The 3rd generation partnership Project, third generation partnership Project), L TE System network architecture is more flat and simplified, and reduces network node and System complexity, thereby reducing System delay, not only providing communication requirements in high-speed movement, but also reducing network deployment and maintenance costs.

However, due to various reasons such as service promotion and investment cost, the 3G and L TE networks can only achieve hot spot coverage in advance in a long period of time, and cannot achieve wide coverage as Global System for mobile communications (GSM) networks, on the other hand, GSM networks have already been very comprehensive in coverage after a long-term large-scale commercial construction, and the network quality is also relatively ideal, and is an optimal means for providing general Circuit Switched (CS) service and Packet Switched (PS) domain service.

For example, after a User Equipment (UE) moves from a coverage of an L TE network or a 3G network to a coverage of a GSM network, the UE needs to re-register with the GSM network, but in some GSM coverage areas with weak network signals, there may be a problem of UE registration failure, which may result in that the UE cannot perform normal communication and the User experience is poor.

Fig. 1 is a schematic flowchart of a cell registration method provided in an embodiment of the present application, and a detailed description will be given below, with reference to fig. 1, from a terminal device side, of the cell registration method in the embodiment of the present application, where the method includes the following steps S101 to S103.

Step S101: reading a system message SIB3 of a first cell when a terminal device moves to a coverage area of a GSM network and needs to perform cell reselection, wherein the SIB3 comprises a first signal strength threshold value of the first cell where the terminal device resides.

Specifically, the terminal device may move from the coverage of the L TE network or the 3G network to the coverage of the GSM network, or may move from the coverage of the GSM network with strong signal strength to the coverage of the GSM network with weak signal strength, that is, if the terminal device finally moves to the coverage of the GSM network and causes a cell to be reselected for registration at a GSM frequency point, the terminal device belongs to the coverage protection range of the coverage of the GSM network in this application.

After the terminal device or a related processor or a related processing module (the same shall not be described again) in the terminal device moves to the coverage of the GSM network, a power scan is initiated under GERAN, that is, under the frequency point of GSM, to obtain and read a System Information Block type3 (SIB 3), which may also be referred to as SI3, of the first cell that needs to be accessed currently. The system message SIB3 includes a minimum access signal strength value required by the terminal device to camp on the first cell, i.e. a first signal strength threshold. The meaning and definition of SIB3 can be referred to the specification of GSM protocol, and specifically, can be referred to the specification in 3GPP TS 44.018. It can be understood that the terminal device will scan the information of multiple cells after initiating the power scan, i.e. receive the received signal strengths of multiple cells. Optionally, the first cell may be a cell with the strongest signal strength among the plurality of cells, or may be a cell that needs to camp on according to other calculation rules, which is not specifically limited in this application.

Step S102: and if the current signal intensity of the first cell is smaller than the first signal intensity threshold and larger than a preset cell resident signal intensity threshold of the terminal equipment, registering the first cell.

Specifically, in the prior art, when it is determined that the current signal strength of the first cell is smaller than the first signal strength threshold, that is, if it is determined that the signal strength (the current signal strength of the first cell) of the terminal device receiving the first cell is smaller than the first signal strength threshold carried in the system message SIB3, it is determined that the terminal device does not satisfy the most basic cell camping condition, that is, cannot camp on the first cell normally. However, each terminal device actually has a different lowest signal strength size of the lowest accessible and camped cell, that is, as long as the cell signal strength received by the terminal device is greater than the lowest signal strength size, the terminal device can register with the cell, but only there may be a problem of poor communication condition due to weak network signals, but at least normal communication can be performed. For example, if the current signal strength of the cell is smaller than the minimum signal strength camping condition of the cell but meets the minimum camping condition of the terminal device, that is, at this time, by using the embodiment of the present application, the first signal strength threshold may be ignored, and the first cell is still continuously registered for communication when it is further determined that the signal strength is greater than the preset cell camping signal strength threshold of the terminal device. Therefore, as long as the condition in this step is satisfied, the terminal device is controlled to continue the registration of the first cell to perform the subsequent communication procedure.

In a possible implementation manner, a Modem layer of the terminal device prestores a preset cell residence signal strength threshold (for example, -105dbm) of the terminal device, where the threshold may be factory setting performed by a technician before factory shipment, or may be a flexibly changed value calculated by combining a relevant algorithm according to cell residence history information during use of the terminal device, and the present invention is not particularly limited to this.

It is understood that if the current signal strength of the first cell is greater than the first signal strength threshold, the first cell may be directly registered according to a cell registration procedure in the prior art.

Fig. 2 is a schematic flowchart of another cell registration method provided in this embodiment, and details of another cell registration method in this embodiment will be described below with reference to fig. 2 from a terminal device side, as shown in fig. 2, the method may include the following steps S201 to S207.

Step S201: the method comprises the steps of acquiring cell signal strength measurement information of a terminal device in a GSM network under the condition that the terminal device moves to the coverage of the GSM network and needs cell reselection.

Specifically, when a terminal device moves to a coverage area of a GSM network and needs to perform cell reselection, the terminal device obtains cell signal strength measurement information of the terminal device in the GSM network through a power scan, where the cell signal strength measurement information includes measurement information of a cell in which the terminal device can detect and receive a signal. For example, the cell signal strength measurement information may be a cell signal strength list including signals received by the terminal device.

Step S202: and determining the cell with the maximum current signal strength as the first cell according to the cell signal strength measurement information.

Specifically, according to the cell signal strength measurement information in step S201, the cell in which the terminal device needs to camp currently is determined, and it is assumed that the cell with the largest current signal strength is determined as the first cell according to the principle of camping on the cell with the largest current signal strength. For example, the terminal device may select a first cell with the strongest current signal strength from the cell signal strength list, and perform an attempt to register, that is, first need to acquire a system message of the first cell, and so on.

Step S203: reading a system message SIB3 of a first cell, wherein the SIB3 comprises a first signal strength threshold value of the first cell where the terminal device resides.

Step S204: and if the current signal intensity of the first cell is smaller than the first signal intensity threshold and larger than a preset cell resident signal intensity threshold of the terminal equipment, registering the first cell.

Specifically, step S203 to step S204 refer to step S101 to step S102 in the embodiment of fig. 1, which are not described herein again.

In a possible implementation manner, the terminal device may store the preset cell-camping signal strength threshold in advance. Further, the terminal device may update the preset cell camping signal strength threshold according to its own cell registration history. That is, the preset cell-resident signal strength threshold may be flexibly changed, and may be set individually according to the actual hardware, software or parameter setting condition of the terminal device, which is not specifically limited in this application.

Step S205: and if the current signal intensity of the first cell is smaller than the first signal intensity threshold and smaller than a preset cell resident signal intensity threshold of the terminal equipment, prohibiting the terminal equipment from registering the first cell within a preset time period.

Specifically, if the terminal device determines that the current signal strength of the first cell is smaller than the first signal strength threshold and smaller than a preset cell camping signal strength threshold of the terminal device, that is, the current signal strength of the first cell does not satisfy the camping condition of the first cell, or the minimum signal strength registration condition of the terminal device itself, the terminal device is prohibited from registering the first cell within a preset time period. The specific implementation manner may be that the cell identifier of the first cell is added to the forbidden registered cell list of the terminal device, that is, when the terminal device needs to perform re-registration subsequently, as long as it is detected that the cell identifier of the cell is stored in the forbidden registered cell list, the terminal device does not acquire the system message of the cell any more and does not initiate network registration within a preset time period, so as to save network resources and unnecessary network overhead.

It is to be understood that the preset time period is not specifically limited in the present application, and may be a shorter time, a longer time, or an infinite time.

Step S206: if the current signal strength of the first cell is smaller than the first signal strength threshold and smaller than the preset cell-camping signal strength threshold, acquiring a system message SIB3 of a second cell, where the system message SIB3 of the second cell includes a second signal strength threshold at which the terminal device camps on the second cell, and the current signal strength of the first cell is greater than the current signal strength of the second cell;

specifically, when it is determined that the terminal device cannot camp on the first cell, the camping target needs to be replaced, at this time, a second cell with the second signal strength may be selected according to the cell signal strength measurement information of the terminal device in step S201 to perform the same determination and operation as the first cell, that is, the system message SIB3 of the second cell is obtained, and it is subsequently determined whether the terminal device can camp on the second cell according to the second signal strength threshold of the second cell and the preset cell camping signal strength threshold of the terminal device, where the determination principle is similar to that of the first cell, and details are not repeated here.

Step S207: and if the current signal intensity of the second cell is smaller than the second signal intensity threshold and larger than a preset cell resident signal intensity threshold of the terminal equipment, registering the second cell.

Specifically, if the signal strength of the second cell is smaller than the second signal strength threshold and larger than the preset cell-camping signal strength threshold of the terminal device, it indicates that although the camping condition of the second cell is not satisfied, the condition that the terminal device camps on the cell is satisfied, so that a registration procedure is initiated to the second cell. It can be understood that, if the second cell cannot camp, the terminal device may continue to query the signal strength list for other cells that can camp, and so on until the terminal device can successfully register to the cell for normal communication.
