Description

The residence reselecting of mobile terminal and device

Technical field

The present invention relates to the communications field, particularly the method and apparatus of the cell reselection of mobile terminal.

Background technology

Along with the development of network, mobile terminal is from single deck tape-recorder list double-card dual-standby (DualSimcardDualStandby till now to be developed, be called for short " DSDS "), there are in the fuselage of DSDS mobile terminal two User Identity module (SubscriberIdentityModule, be called for short " SIM ") card, or two soft SIM card (virtual SIMs, the SIM information of corresponding software form), or in a SIM card, there are 2 parts of SIM information, hereinafter by two independently SIM card, or there is a SIM card of two user SIM information or two soft SIM card are referred to as two SIM cards.Therefore, two SIM cards not only represent the SIM card of two example, in hardware.User only needs use DSDS mobile terminal, just conveniently can operate two SIM cards in this DSDS.Existing DSDS mobile terminal can have two kinds of mode of operations: the first is single pass mode, wherein one data connection state can only be in two SIM cards, an other card is in holding state, namely the same radio frequency (RadioFrequency in two SIM cards multiplexing DSDS mobile terminal, be called for short " RF ") resource, the second is bilateral pattern, and two SIM cards can be in data connection state, and namely two SIM cards have independently RF resource.But for the consideration of technology and cost, major part DSDS mobile terminal only supports single pass mode, now, when mobile terminal standby, two SIM cards of DSDS pattern are all in holding state, except monitoring except ICQ, also need to carry out adjacent cell synchronous, receive adjacent domain system message, receive serving cell system message etc.When user uses mobile terminal Internet access, one SIM card of DSDS pattern can be in data connection state, need the RF resource always taking mobile terminal, and an other SIM card is in holding state, still need to monitor ICQ, read system message and execution synchronously, and judge whether to start cell reselection, if when standby SIM card performs cell reselection, need to seize RF resource with the SIM card being in data connection state.

In prior art, mobile terminal is in the process of movement, mobile terminal will meet the re-selecting cell of community as SIM card of C1 criterion and C2 criterion in the adjacent cell of standby SIM card, C1 criterion is that path loss parameter is greater than zero, C2 criterion is that reselecting parameters is maximum, then standby SIM card is from current persistent district gravity treatment to this re-selecting cell, like this, as long as the current persistent district of standby SIM card does not meet C1 criterion or C2 criterion, just need to carry out gravity treatment continually, and SIM card standby during gravity treatment takies RF resource, the SIM card of transmission data abdicates RF resource, cause the time decreased of the SIM card transmission data transmitting data, and then transmit speed and the performance reduction of data.

Fig. 2 shows residence reselecting 200 schematic diagram of the mobile terminal that the embodiment of the present invention provides, this mobile terminal comprises the first SIM card and the second SIM card, in first SIM card and the second SIM card, SIM card can use the radio frequency resource of mobile terminal, suppose that this first SIM card is in holding state, this second SIM card is in data connection state, this second SIM card takies radio frequency resource, and namely this mobile terminal belongs to dual-card dual-standby single-pass mobile terminal.The method 200 such as can be performed by mobile terminal, and this mobile terminal is such as mobile phone.As shown in Figure 1, the method 200 comprises:

S210, at least one adjacent cell path loss parameter of this first SIM card is greater than first threshold to mobile terminal and the adjacent cell with maximum reselecting parameters adds the candidate camping cell list of this first SIM card, this candidate camping cell list comprises at least one candidate camping cell, namely, when mobile terminal determination target persistent district, in the list of candidate camping cell, there is candidate camping cell;

S220, when this mobile terminal determines that the current persistent district of this first SIM card meets trigger condition, this mobile terminal determines the target persistent district of this first SIM card from this candidate camping cell list, wherein, this trigger condition comprise following at least one item: the channel quality parameter of this mobile terminal and this current persistent district is lower than Second Threshold, the message of this current persistent district that this mobile terminal receives has error code, or the path loss parameter of this current persistent district is lower than this first threshold;

S230, this mobile terminal by this first SIM card from this current persistent district gravity treatment to this target persistent district.

The C1 value that path loss parameter can specify for prior art reselection protocol, C1=moves RLA_C-RXLEV_ACCESS_MIN-MAX ((MS_TXPWR_MAX_CCH-P), 0); Wherein RLA_C represents that mobile terminal receives the average level (reflecting the signal strength signal intensity of this community) of community, and RXLEV_ACCESS_MIN represents that community allows the minimum levels (minimum permissible value) of mobile terminal access; MS_TXPWR_MAX_CCH represent mobile terminal access community time spendable maximum transmit power level; P represents the peak power output of mobile terminal.C1 criterion, for being greater than first threshold when C1 value, if this first threshold can be zero, namely meeting adjacent cell that C1 value is greater than first threshold and can think and meet C1 criterion at least one adjacent cell of the current persistent district of a SIM; Reselecting parameters is the C2 value that in prior art, agreement specifies, C2=C1+/-CELL_RESELECT_OFFSET, CELL_RESELECT_OFFSET represents cell reselection offset, agreement regulation is also different according to the value of the different CELL_RESELECT_OFFSET of make-up time, and C2 criterion is as re-selecting cell using community maximum for C2 value.Mobile terminal is greater than first threshold and the maximum adjacent cell of C2 value adds candidate camping cell list by meeting C1 value in the adjacent cell of the current persistent district of a SIM, when current persistent district meets trigger condition, select target persistent district from this candidate camping cell list.

Specifically, along with the movement of mobile terminal, second is in data connection state takies radio frequency resource, the community needing constantly to select Received signal strength best is resident, networking paging is monitored when first SIM card is standby, receive adjacent domain system message, receive serving cell system message, it is synchronous etc. to carry out adjacent cell.Better data are transmitted in order to make the second SIM card, the adjacent cell of the first SIM card is when meeting path loss parameter and be greater than first threshold and having maximum reselecting parameters, do not carry out gravity treatment, but be greater than first threshold and the adjacent cell with maximum reselecting parameters puts into candidate camping cell list by meeting path loss parameter, namely the first SIM card also can receive signal in current persistent district, the signal just received in current persistent district is not greater than first threshold and the signal quality that receives of the community with maximum reselecting parameters is good meeting path loss parameter, until a current persistent district of SIM meets: the channel quality parameter of mobile terminal and this current persistent district is lower than Second Threshold, the message of this current persistent district that mobile terminal receives has error code, when the C1 value of current persistent district is less than at least one in first threshold three conditions, mobile terminal determines target persistent district in the list of candidate camping cell, mobile terminal by the persistent district of the first SIM card from the gravity treatment of current persistent district to target persistent district, the paging of monitoring networking is carried out in target persistent district, receive adjacent domain system message, receive serving cell system message, it is synchronous etc. to carry out adjacent cell.Gravity treatment is not carried out when meeting path loss parameter and be greater than first threshold and there is maximum reselecting parameters, but the signal quality that mobile terminal is receiving the first SIM card is deteriorated, the message received has error code or path loss parameter to be less than or equal to first threshold (as zero), current persistent district cannot make this mobile terminal normal received signal, as caused network monitor, adjacent cell is synchronous, the reception of system message makes a mistake, in the list of candidate camping cell, now determine that gravity treatment is carried out again in the target persistent district of the first SIM card.

Therefore, list community, candidate camping cell is determined by path loss parameter and reselecting parameters, when the current persistent district of the first SIM card meets trigger condition, a target persistent district is determined from the list of persistent district to be selected, like this, the adjacent cell of the first SIM card is when meeting path loss parameter and be greater than first threshold and having maximum reselecting parameters, do not carry out gravity treatment, but be greater than first threshold and the adjacent cell with maximum reselecting parameters puts into candidate camping cell list by meeting path loss parameter, gravity treatment is carried out again when meeting trigger condition, reduce the number of times of the first SIM card persistent district gravity treatment, avoid frequent gravity treatment to cause and seize the RF resource used when the second SIM card transmits data, thus the resource that the second SIM card takies RF can be improved, the time of the second SIM card transmission data can be increased, also the performance of the second SIM card transmission data can be improve.

As an embodiment, mobile terminal determines the target persistent district of the first SIM card from the list of candidate camping cell, comprise: mobile terminal using candidate camping cell maximum for reselecting parameters in the list of candidate camping cell as this target persistent district, when current persistent district meets trigger condition, the candidate camping cell that C2 value can be selected in the list of candidate camping cell maximum is as target persistent district, also can in the list of candidate camping cell, select any one candidate camping cell as Target cell, the embodiment of the present invention be not limited thereto.

As an embodiment, when mobile terminal determines that the reselecting parameters (C2 value) of the first candidate camping cell in the list of candidate camping cell is less than reselecting parameters (the C2 value) of current persistent district, first candidate camping cell is deleted by mobile terminal from the list of candidate camping cell, namely carry out resident in order to the candidate camping cell in real-time guarantee candidate camping cell list is all more suitable for the first SIM card than current persistent district, this candidate camping cell list will upgrade dynamically.

As an embodiment, the channel quality parameter of mobile terminal and current persistent district is lower than Second Threshold, comprise: the signal energy that mobile terminal receives current persistent district receives the signal to noise ratio of the signal of current persistent district lower than the 4th threshold value (as 5dB) lower than the 3rd threshold value (as-85dB) and/or mobile terminal, namely signal energy and/or signal to noise ratio can be adopted to represent channel quality parameter, when adopting the signal energy received to represent channel quality parameter, 3rd threshold value (as-85dB) can be Second Threshold, or channel quality algorithm determination Second Threshold can be utilized according to the 3rd threshold value, when adopting the signal to noise ratio of the signal received to represent channel quality parameter, the 4th threshold value can be Second Threshold, or can utilize channel quality algorithm determination Second Threshold according to the 4th threshold value, when adopting signal energy and signal to noise ratio to represent channel quality parameter, also can utilize channel quality algorithm determination Second Threshold according to the 3rd threshold value and the 4th threshold value simultaneously, channel quality parameter also can represent by other parameter, as signal and noise distortion ratio or Signal to Interference plus Noise Ratio come, the embodiment of the present invention is not limited thereto.
