Accompanying drawing explanation
Accompanying drawing described herein is used to provide further understanding of the present application, forms the application's a part, and the application's schematic description and description is used for explaining the application, does not form the improper restriction to the application.
Fig. 1 is the functional block diagram after the communication system of one embodiment of the invention is simplified.
Fig. 2 is in the communication system of Fig. 1, for a plurality of subscriber equipmenies are set, carries out the flow chart after an embodiment that minimum road test records the method for returning of metric data simplifies.
Embodiment
Below will coordinate relevant drawings that the present invention's embodiment is described.In these accompanying drawings, identical label represents same or similar element or method flow.
Fig. 1 is the functional block diagram after the communication system 100 of one embodiment of the invention is simplified.Communication system 100 comprises minimum road test server 110, remote access network node (remote access network node, RAN node) 130 and 150, and subscriber equipment (user equipment, UE) 160 and 180.In order to make drawing concisely be easy to explanation, other elements and annexation are not illustrated in Fig. 1.For example, communication system 100 can separately comprise one or more minimum road test servers, more remote access network node and/or more subscriber equipment.
In network terminal, minimum road test server 110 is used for arranging the relevant running that minimum road test measures (Minimization of Drive Tests measurement).
Remote access network node 130 and 150 is configured to carry out wireless telecommunications with subscriber equipment 160 and 180, and can by modes such as Node B (node B), enode b (evolved node B), home node-b (home node B) and base transceiver station (base transceiver station), realize respectively.
Fig. 2 is in the communication system 100 of Fig. 1, for a plurality of subscriber equipmenies are set, carries out the flow chart after an embodiment that minimum road test records the method for returning of metric data simplifies.Below arrange in pairs or groups Fig. 1 and Fig. 2 further illustrates the function mode of communication system 100.In order to make drawing simple and clear, minimum road test server 110 and remote access network node 130 and 150 represent to describe with " network terminal " in Fig. 2.
In flow process 200, network terminal can transmit configuration information (configuration message) to subscriber equipment 160 and 180, with equipment for indicating user 160 and 180, is exclusively used in the first lead code that return minimum road test records metric data.For example, can from the set of existing 64 lead codes, select one of them as the first lead code, and to assign the first selected lead code be to be exclusively used in the return that minimum road test records metric data.In one embodiment, network terminal can be used " record measures configuration information " (Logged Measurement Configuration message) to be exclusively used in to subscriber equipment 160 and 180 the first lead code that return minimum road test records metric data.
In flow process 210, network terminal can transmit the call information (paging message) that includes report pointer (reporting indicator), in order to the subscriber equipment 160 and 180 arranging in idle mode, carries out the return running that minimum road test records metric data.
In addition, in the coverage of remote access network node, may have a plurality of subscriber equipmenies, and different subscriber equipmenies can use (paging cycle) receipt of call information of different calling cycles.Therefore, network terminal can be sent call information to a plurality of subscriber equipmenies in the different calling cycles, make network terminal to the minimum road test that obtains sufficient amount, record one or more subscriber equipmenies of metric data, obtain more efficiently minimum road test and record metric data.
In one embodiment, when subscriber equipment meets one or more report condition (reporting constraint), subscriber equipment can be returned minimum road test to network terminal and record metric data.Report condition can in be built in the memory storage of subscriber equipment, or send in advance subscriber equipment to by network terminal.For example, network terminal can transmit report pointer with configuration information and/or call information, with equipment for indicating user, uses which kind of report condition.For example, network terminal can transmit report condition table to subscriber equipment, a plurality of thresholds of the data volume that this report condition table comprises minimum road test metric data.When report pointer equipment for indicating user, answering the threshold in operation report condition table is 20KB, and the subscriber equipment that has a minimum road test metric data that is greater than 20KB data volume just can be returned minimum road test to network terminal and record metric data.
In flow process 220, when subscriber equipment receives after call information, if subscriber equipment meets report condition, can transmit the first lead code to network terminal.In the present embodiment, subscriber equipment can use entity direct access communications channels (physical random access channel, PRACH) to carry out RAP for the first time, to transmit the first lead code.
In flow process 230, the quantity of the first lead code that network terminal meeting foundation receives, and determine that in the second RAP, authorizing subscriber equipment records the ascending resource of metric data for returning minimum road test.In one embodiment, network terminal can be used for transmitting according to subscriber equipment the arbitrary access resource of the first lead code, and calculates the quantity of the first lead code receiving.In another embodiment, network terminal also can be according to the power ratio (power ratio) of arbitrary access resource, and calculates the quantity of the first lead code receiving.If network terminal does not receive the first lead code, at entity direct access communications channels, do not detect suitable power ratio yet, representative does not have subscriber equipment need to carry out the return running that minimum road test records metric data, and network terminal can not authorized ascending resource and carried out the return running that minimum road test records metric data to subscriber equipment.
In flow process 240, network terminal can transmit first arbitrary access corresponding with the first lead code to subscriber equipment and respond (random access response), to indicate the first ascending resource and dedicated pointer.In the second RAP, subscriber equipment can use the first ascending resource to transmit the second lead code, and by dedicated pointer, carries out the reception running of the second arbitrary access response.For example, network terminal can be exclusively used in the interim identification code of special-purpose arbitrary access radio net (random access radio network temporary identifier, RA-RNTI) that return minimum road test records metric data by one and be set to dedicated pointer.
In flow process 250, when subscriber equipment receives after the first arbitrary access response, subscriber equipment can select a lead code be used as the second lead code at random, and with the first arbitrary access, responds the first indicated ascending resource and transmit the second lead code.In addition, the second lead code is configured to different from the first lead code.If subscriber equipment is not received the first arbitrary access response, subscriber equipment can be ended the return flow process that minimum road test records metric data, and maintains idle mode.
In flow process 260, network terminal can transmit the second arbitrary access response to subscriber equipment.The second arbitrary access is responded and is comprised one or more medium access control (media access control, MAC) packet data unit (packet data units, PDUs).Each medium access is controlled packet data unit and can be indicated one or more second ascending resource to transmit solicited message for subscriber equipment, and the up time reference of one or more correspondence (uplink timing reference) carries out the running of uplink synchronous for subscriber equipment.
In traditional arbitrary access flow process, subscriber equipment can use the interim identification code of the radio net of non-special use (radio network temporary identifier, RNTI), to find, carry the medium access control packet data unit that arbitrary access is responded, wherein the interim identification code of the radio net of non-special use can be correlated with and be used for transmitting the ascending resource of lead code with subscriber equipment.In the present embodiment, a plurality of subscriber equipmenies are configured to use the same interim identification code of special-purpose arbitrary access radio net that return minimum road test records metric data that is exclusively used in, and to find, carry the medium access control packet data unit that the second arbitrary access is responded.If control packet data unit because subscriber equipment continues to find medium access by the interim identification code of radio net of non-special use, the interim identification code of arbitrary access radio net that records metric data for returning minimum road test may produce and conflict with the situation of using the interim identification code of other networks.Therefore,, even if subscriber equipment uses different ascending resources, still can cause the generation of competition (contention).
In addition, because can receiving the second arbitrary access by the interim identification code of same special-purpose arbitrary access radio net, a plurality of subscriber equipmenies respond, therefore,, even if different subscriber equipmenies transmits the second lead code at different ascending resources, still cannot avoid the generation of competition.In order to address this problem, the second arbitrary access that network terminal can be controlled packet data unit at medium access increases special-purpose identification in responding.When a plurality of subscriber equipmenies transmit the second lead code in different ascending resources, special-purpose identification can be used to identify different subscriber equipmenies.For example, network terminal can transmit according to subscriber equipment the ascending resource of the second lead code, and produces the special use identification corresponding to this subscriber equipment.Therefore, even if subscriber equipment transmits identical lead code in different resources, network terminal still can be identified each subscriber equipment, and subscriber equipment also can correctly find the medium access that carries the second lead code to control packet data unit.
Because subscriber equipment records the interim identification code of special-purpose arbitrary access radio net of metric data report by using special-purpose identification and being exclusively used in return minimum road test, to find, carry the medium access of the second access response and control packet data unit.Therefore,, in flow process 270, subscriber equipment can use the second arbitrary access to respond the second indicated ascending resource and transmit solicited message.In addition,, for the function that provides competition to solve, subscriber equipment can transmit the subscriber equipment specific identity code (for example, subscriber equipment identity UE identity) that is specific to this subscriber equipment in solicited message.
In flow process 280, network terminal can receive solicited message, and the echo message that transmission includes scheduling plan is to subscriber equipment.Scheduling plan comprises for allowing subscriber equipment return minimum road test record the 3rd ascending resource of metric data.
In addition, network terminal also can transmit competition and solve identity code in echo message, is used for comparing running with the subscriber equipment specific identity code of flow process 270, with the mechanism that provides competition to solve.When competition solution identity code is identical with subscriber equipment specific identity code, competition solves successfully.If both are not identical, competition solves unsuccessfully, and subscriber equipment can be ended the return flow process that minimum road test records metric data.
In flow process 290, subscriber equipment can, according to the scheduling plan in echo message, record metric data and return minimum road test.
At subscriber equipment, complete return minimum road test and record after metric data, subscriber equipment can be removed running by being used for depositing the memory that minimum road test records metric data, to store follow-up minimum road test metric data or other data.And subscriber equipment still maintains idle mode.
In the above-described embodiment, network terminal can arrange a plurality of subscriber equipmenies of the coverage that is positioned at remote access network node efficiently, carries out the return running that minimum road test records metric data.In addition,, by operation report pointer in call information, network terminal can more flexiblely be adjusted the threshold that return minimum road test records metric data.
In the above-described embodiment, special use identification, subscriber equipment specific identity code and competition by user's equipment solve identity code etc., even if a plurality of subscriber equipmenies need to be returned minimum road test and record metric data, also can provide suitable competition settlement mechanism.
