Technical field
The present invention relates to communication technical field, relate more specifically to based on the inter-system measuring method of single baseband chip dual link framework and the method that realizes the single mode to be accessed of multimode based on single baseband chip dual link framework.
Background technology
Along with the development of mobile communication technology, support simultaneously the multimode terminal of 2G/3G/4G wireless access technology to arise at the historic moment.At present, two kinds of frameworks of the general employing of this multimode terminal are namely singly treated framework based on the multimode dual link framework of single baseband chip with based on the multimode of single baseband chip.In order both to take full advantage of ripe 2G/3G (for example GSM/UMTS) network, can utilize again simultaneously LTE bandwidth of network advantage, the multi mode terminal terminal can adopt GSM/UMTS and LTE multimode dual link framework, so that the GSM/UMTS module is in CS (circuit switching) business, simultaneously so that the LTE module be in PS (packet switching) business.And for this class multimode terminal of card of surfing Internet (for example dongle card of surfing Internet and MIFI card of surfing Internet), it mainly utilizes based on the multimode of single baseband chip and singly treats framework, namely support the single mode to be accessed of multimode, but only with a kind of access module as holotype (pattern of activation).For example, card of surfing Internet with the LTE pattern as holotype, and with the GSM/UMTS pattern as auxiliary pattern, realize data service in order to take full advantage of LTE bandwidth of network advantage.
Fig. 1 shows the schematic block diagram of singly treating the terminal of framework based on single baseband chip multimode dual link/multimode.As shown in Figure 1, baseband chip 10 comprises a RF interface 101 and the 2nd RF interface 102.The one RF interface 101 for example is used for the RF chip of coupling LTE pattern, and the 2nd RF interface 102 for example is used for the RF chip of coupling EDGE/UMTS mode common.Baseband chip 10 can be controlled independently via a RF interface 101 and the 2nd RF interface 102 operation of two RF chips.
In Fig. 2, the interaction diagrams of protocol layer and physical layer when showing the terminal that adopts framework shown in Figure 1 as an example of LTE and GSM/UMTS multimode example and carrying out isosystem measurement.As shown in Figure 2, in LTE and GSM/UMTS multimode dual link situation, the protocol layer 21a of LTE module respectively under the physical layer 21b of LTE module and the LTE GSM/UMTS measurement module 21c send native system measurement demand and isosystem measurement demand, measure and isosystem measurement to realize native system.GSM/UMTS measurement module 21c carries out measuring process based on measurement demand separately respectively under the physical layer 21b of LTE module and the LTE, and measurement result is separately sent to the protocol layer 21a of LTE module.In like manner, the protocol layer 22a of GSM/UMTS module respectively under the physical layer 22b of GSM/UMTS module and the GSM/UMTS LTE measurement module 22c send native system measurement demand and isosystem measurement demand, measure and isosystem measurement to realize native system.LTE measurement module 22c carries out measuring process based on measurement demand separately respectively under the physical layer 22b of GSM/UMTS module and the GSM/UMTS, and measurement result is separately sent to the protocol layer 22a of GSM/UMTS module.
Similarly, singly treat in the situation at LTE and GSM/UMTS multimode, one in LTE pattern and the GSM/UMTS pattern as holotype (pattern of activation), and another is as auxiliary pattern (nonactivated pattern).For example, in the situation that the LTE pattern is holotype and the GSM/UMTS pattern is auxiliary pattern, the RF chip that is used for the GSM/UMTS pattern is not worked, isosystem measurement process and the isosystem measurement process in LTE and the GSM/UMTS multimode dual link situation for the GSM/UMTS pattern under the LTE pattern are similar, need to carry out measuring process based on the isosystem measurement demand by GSM/UMTS measurement module 21c under the LTE equally, and measurement result be sent to the protocol layer 21a of LTE module.
This shows, in existing inter-system measuring method, most of work realizes in physical layer, has increased the weight of the burden of physical layer, for power saving, to save memory resource unfavorable.

Embodiment
In first aspect, embodiments of the present invention provide a kind of inter-system measuring method based on single baseband chip dual link framework.The below is with reference to Fig. 3 and Fig. 4 description inter-system measuring method according to the embodiment of the present invention.
Fig. 3 shows the flow chart according to the inter-system measuring method of an embodiment of the invention.As shown in Figure 3, at step S301, in response to receiving measurement request message from network side, the protocol layer of the first communication pattern module sends measurement demand for the second communication pattern to the protocol layer of second communication mode module.For example comprise the information of adjacent cells for the second communication pattern in this measurement demand.The first communication pattern for example can be the LTE pattern, and the second communication pattern for example can be GSM/UMTS double-mode single-standby pattern.More specifically, the second communication pattern for example can be GSM/TD-SCDMA double-mode single-standby pattern.
Described measurement demand can be carried in the measurement request message.For example, when terminal accesses the network of the first communication pattern, network side (for example base station) can send measurement request message to terminal, carry in this measurement request message under the demand of certainly measuring of the first communication pattern and the first communication pattern for the isosystem measurement demand of second communication pattern.
In addition, when the system mode of the first communication pattern changed, the isosystem measurement demand for the second communication pattern under the first communication pattern also can change.Therefore network side also can send measurement request message to terminal, carries the isosystem measurement demand that has changed in this measurement request message.For example, be GSM/UMTS double-mode single-standby pattern in the situation that the first communication pattern is LTE pattern, second communication pattern, the system mode of LTE pattern is RRC CONNECED (RRC connection) state or when being the IDLE state by RRC CONNECED state-transition, the isosystem measurement demand for GSM/UMTS double-mode single-standby pattern under the LTE pattern also can change by IDLE (free time) state-transition.For example, under the IDLE of the LTE pattern state and under the RRC CONNECED state, the adjacent cell of the different system of required measurement is different.Therefore, the system mode of LTE pattern by the IDLE state-transition be RRC CONNECED state or by RRC CONNECED state-transition be the IDLE state constantly, network side can send the measurement request message that carries the neighboring BS information that has changed to terminal.
According to an embodiment, the physical layer of the first communication pattern module receives the measurement request message that carries measurement demand from network side, the protocol layer of the first communication pattern module is in response to receive this measurement request message from network side, resolve this measurement request message with the acquisition measurement demand, and will send to for the measurement demand of second communication pattern the protocol layer of second communication mode module.The protocol layer of second communication mode module is determined measuring period based on measurement demand.For example, when the system mode of the first communication pattern changes, isosystem measurement demand for the second communication pattern under the first communication pattern also can change, and the protocol layer of second communication mode module can be determined corresponding measuring period according to different measurement demands.For example, when the first communication pattern was the LTE pattern, be confirmed as 5s the measuring period of carrying out isosystem measurement under the IDLE of LTE pattern state, and be confirmed as 480ms the measuring period of carrying out isosystem measurement under RRC CONNECED state.
Then, at step S302, the second communication mode module is carried out measuring process based on measurement demand and measurement result is sent to the protocol layer of the first communication pattern module via its protocol layer.Afterwards, the protocol layer of the first communication pattern module can be carried out based on this measurement result and measure judgement.Because it is well known in the art carrying out the process of measuring judgement based on measurement result, therefore omits its detailed description at this.
According to an embodiment, the second communication mode module is carried out measuring process based on measurement demand and comprised: the physical layer of second communication mode module receives measurement demand from the protocol layer of second communication mode module, carry out measuring process based on this measurement demand, and measurement result is sent to the protocol layer of second communication mode module.The protocol layer of second communication mode module sends to measurement result according to measuring period the protocol layer of the first communication pattern module.For example, within each measuring period, the protocol layer of second communication mode module only sends the one-shot measurement result to the protocol layer of the first communication pattern module.Consider for power saving, the protocol layer of second communication mode module can send measurement result by the protocol layer to the first communication pattern module during the first communication pattern module receives from the beep-page message of the first communication pattern network.
Should be appreciated that " protocol layer " mentioned in the embodiments of the present invention is the general designation to the high level more than the physical layer.It should also be understood that, in inter-system measuring method according to the embodiment of the present invention, because the first communication pattern module and second communication mode module are based on same baseband chip, communication protocol operates on the processor, thereby communicating by letter between the protocol layer of the protocol layer of easily realizing the first communication pattern module and second communication mode module.Therefore, the isosystem measurement module that is used for the execution isosystem measurement in the physical layer can be saved, but finished respectively the measurement of native system by each communication pattern module, and the measurement result of native system is sent to different system communication module, with as the isosystem measurement result.For example, the first and second communication pattern modules are finished respectively the measurement of native system, the second communication mode module sends to the measurement result of native system by its protocol layer the protocol layer of the first communication pattern module, with as under the first communication pattern for the measurement result of second communication pattern.Can reduce thus physical layer complexity, alleviate the burden of physical layer.
The below is with reference to Fig. 4, take the first communication pattern as the LTE pattern, the second communication pattern as GSM/UMTS double-mode single-standby pattern as example, a concrete application scenarios of inter-system measuring method shown in Figure 3 is described.As shown in Figure 4, schematically show the protocol layer of LTE module and the protocol layer of GSM/UMTS module with piece 401a and 402a respectively, and schematically show the physical layer of LTE module and the physical layer of GSM/UMTS module with piece 401b and 402b respectively.
In application scenarios shown in Figure 4, the isosystem measurement process for the GSM/UMTS pattern under the LTE pattern is as follows.At first, the physical layer 41a of LTE module receives measurement request message from network side (for example base station), and it is reported the protocol layer 41b (step S401a) of LTE module.Carry in this measurement request message under the demand of certainly measuring of LTE pattern and the LTE pattern for the isosystem measurement demand of GSM/UMTS pattern.The protocol layer 41b of LTE module resolves this measurement request message obtaining under the LTE pattern isosystem measurement demand (being called for short " GSM/UMTS measurement demand ") for the GSM/UMTS pattern, and sends it to the protocol layer 42b (step S402a) of GSM/UMTS module.The protocol layer 42b of GSM/UMTS module is forwarded to the GSM/UMTS measurement demand physical layer 42a (step S403a) of GSM/UMTS module.The physical layer 42a of GSM/UMTS module carries out measuring process based on this GSM/UMTS measurement demand, and measurement result is sent to the protocol layer 42b (step S404a) of GSM/UMTS module.The protocol layer 42b of GSM/UMTS module is according to sending this measurement result (step S405a) to the protocol layer 41b of LTE module measuring period.
Similarly, in application scenarios shown in Figure 4, the isosystem measurement process for the LTE pattern under the GSM/UMTS pattern is as follows.At first, the physical layer 42a of GSM/UMTS module receives measurement request message from network side (for example base station), and it is reported the protocol layer 42b (step S401b) of GSM/UMTS module.Carry in this measurement request message under the demand of certainly measuring of GSM/UMTS pattern and the GSM/UMTS pattern for the isosystem measurement demand of LTE pattern.The protocol layer 42b of GSM/UMTS module resolves this measurement request message obtaining under the GSM/UMTS pattern isosystem measurement demand (being called for short " LTE measurement demand ") for the LTE pattern, and sends it to the protocol layer 41b (step S402b) of LTE module.The protocol layer 41b of LTE module is forwarded to the LTE measurement demand physical layer 41a (step S403b) of LTE module.The physical layer 41a of LTE module carries out measuring process based on this LTE measurement demand, and measurement result is sent to the protocol layer 41b (step S404b) of LTE module.The protocol layer 41b of LTE module is according to sending this measurement result (step S405b) to the protocol layer 42b of GSM/UMTS module measuring period.Afterwards, the protocol layer 42b of GSM/UMTS module can according to mode well known in the art, carry out the measurement judgement based on this measurement result.
Be to be understood that, with reference to the application scenarios that the inter-system measuring method of Fig. 3 and Fig. 4 description both can have been tackled single SIM card dual link and the double SIM card dual link (double SIM card jack per line) of same operator, the application scenarios that also can tackle the double SIM card dual link (double SIM card is jack per line not) of a plurality of operators.In the application scenarios for single SIM card dual link of same operator and double SIM card dual link, for example as shown in Figure 4, be GSM/UMTS double-mode single-standby pattern in the situation that the first communication pattern is LTE pattern, second communication pattern, can be with CS (circuit switching) service log-on/be based upon under the GSM/UMTS double-mode single-standby pattern, simultaneously with PS (packet switching) service log-on/be based upon under the LTE pattern, both can take full advantage of thus ripe GSM/UMTS network implementation realize voice professional, and can utilize again LTE bandwidth of network advantage to realize data service.
In addition, by the dual link framework based on single baseband chip is suitably configured, can singly treat mode so that Fig. 3 and the inter-system measuring method based on single baseband chip dual link framework shown in Figure 4 are equally applicable to multimode.Fig. 5 shows according to flow chart an embodiment of the invention, realize the method for the single mode to be accessed of multimode based on single baseband chip dual link framework.
In method shown in Figure 5, at first at step S501, access the first communication pattern network and standby under the first communication pattern by the first communication pattern module.Then, at step S502, by second communication mode module access second communication mode network, and under the second communication pattern paging receiving message but this beep-page message is not responded optionally.The first communication pattern module and second communication mode module are based on same baseband chip.
In the present embodiment, because the first communication pattern and second communication pattern all are in state of activation, therefore can under the second communication pattern, realize for the isosystem measurement of second communication pattern under the first communication pattern.This isosystem measurement for example can adopt above with reference to the described inter-system measuring method of Fig. 3 and realize.
According to a specific embodiment, the first communication pattern is the LTE pattern, and the second communication pattern is GSM/UMTS double-mode single-standby pattern.That is, terminal standby under the LTE pattern, paging receiving message under the GSM/UMTS pattern but this beep-page message is not responded is only finished the measuring process under the GSM/UMTS pattern; Perhaps terminal standby under the LTE pattern, paging receiving message not under the GSM/UMTS pattern.In the present embodiment, the isosystem measurement for the GSM/UMTS pattern can be realized under the GSM/UMTS pattern under the LTE pattern.This isosystem measurement for example can adopt above with reference to the described inter-system measuring method of Fig. 4 and realize.
